Description

TECHNICAL FIELD

[001] The invention relates to a process and a system in a vehicle. Specifically, the invention provides a mechanism for the regulation of load transfer in a vehicle, comprising a bogie with at least one front wheel and one rear wheel.

BACKGROUND

[002] Vehicles with a bogie and/or a three-axle bogie are increasingly common in today's vehicle fleets, partly because of accessibility and partly because of carrying capacity. These vehicles are used in different applications and have different accessibility requirements and different requirement on how to use cargo transfers.

[003]Vehicle in this context means, for example, a truck, an articulated truck, a pickup truck, a van. a trailer, a service truck, a car, an emergency vehicle, a container, a moving truck, ATV, a drag platform, an excavator, a crane truck, a tanker, a motorcycle, a wheeled cargo vehicle, a cleaning vehicle, a scooter, a limousine, a sports car, a racing car, a car with shock absorbers, a bed truck, a watercraft trailer, a lawn mower, a tank , a sled, a snow tractor, a trailer, an all-terrain vehicle, a go-kart, a bus, a harvester and a harvester, a farm machinery, or a manned or unmanned motor vehicle, designed for land geographic transport.

[004]A trick is a device that is usually located under the rear section below a car or vehicle with 2, 3, 4, 5, etc. wheelsets, with the objective of distributing the vehicle load on several wheelsets, thereby reducing the pressure on the wheelset, increasing the load capacity and also distributing the wheel pressure on the tread, which, for example, ensures a less wear and tear on the raceways and displaces less gravel when the vehicle is driven on a gravel road.

[005] Trucks and similar vehicles are often built with a trick, especially when they are used for heavy transport. A trick has at least two wheelsets, which have a center distance of less than 2 meters. In cases where a vehicle is built with three wheelsets, and the distance between the first and third wheelsets is not less than five meters, this is often called a "three wheelset" rather than a trick.

[006] A truck bogie is usually non-rotating as in rail vehicles, which causes a certain type of wear. To eliminate or at least reduce this type of wear, the wheels on one of the wheelset are sometimes rotatable, so that they hang outward when the front wheels turn, following the oscillation radius.

[007] A three-wheeler truck is the term used for the special three-wheeler truck wheel. One or more wheels can be located at each end of the wheel.

[008] The wheel wheels, which are included in a truck wheel, can all be driven, in which case they are called traction wheels, or simply rolling, in which case they are called support wheels. A trick can be comprised of only traction wheels, or a combination of at least one traction wheels and one or more support wheels. If more than one wheel is driving, constructions are sometimes called tandem or three units in a row.

[009] When a load transfer is conducted on a vehicle with a three wheel truck, see Figure 1A, which has a support wheel and two traction wheels, according to the prior art, the weight is first transferred. wheel support wheel for both drive wheelset, see Figure 1B. The load is then transferred from one traction wheel to the other wheel, see Figure 1C. The reason for making this load transfer may be to increase the pressure against the base, to increase friction and thus obtain better traction.

[010]According to the existing technology, it is predetermined through parameters of which wheel drive the weight should be transferred, usually from the front wheel drive to the rear wheel drive. This means that the user does not have any possibility to adapt the load transfer to his needs. It is only possible to select whether all wheelsets in the truck are to be coupled, or whether the load transfer is to be made to a certain predetermined traction wheelset.

[011] To summarize, there is a need to improve the handling and control of load transfers in vehicles with bogie wheels.

ABSTRACT

[012] An object of this invention is, therefore, that it is possible to adapt and control load transfers in a vehicle with a bogie wheel, with two or more wheels, to solve at least one of the problems specified above, and, of that way, get an optimized vehicle.

[013] According to a first aspect of the invention, this object is achieved by a process to adjust the load transfers in a vehicle, which comprises a bogie with at least one front and one rear wheel. The process comprises determining the vehicle's drive conditions. Further, the process comprises determining a load transfer setting for the vehicle, based on the vehicle's determined driving conditions, by adjusting a driver-driven control to select a load transfer setting. The process also comprises the generation of a control signal in a control device, which can be effected by the driver-controlled control, to regulate the load transfer configuration according to the regulation made by the driver-controlled control. Even more, the process also comprises sending the control signal generated from the control device to a control mechanism, for transfer of load introduced together with the bogie. In addition, the process comprises the adjustment of load transfers in the truck through the control mechanism, according to the adjustment made by the control commanded by the driver.

[014] According to a second aspect of the invention, this object is achieved by a system in a vehicle. The system comprises a bogie, with at least a front wheel and a rear wheel, to adjust the load transfers on the vehicle. The system comprises a driver-driven control for selecting a load transfer setting based on the vehicle's determined driving conditions. In addition, the system comprises a control device, which can be effected by driver-controlled control and adapted to generate and send a control signal. Furthermore, the system comprises a control mechanism, adapted to receive the control signal and adjust the load transfer in the truck, according to the adjustment made by the control commanded by the driver.

[015] By providing the adjustment of the load transfer between the traction wheels, and, in this way, by varying the base of the wheel, it will be possible to adjust the characteristics of the vehicle, such as the inclination radius, the control characteristics and the wheel load, to the determined driving conditions that the driver experiences. In this way, an improvement of the vehicle is obtained.

[016] A variable load transfer between traction wheels can also make transport more efficient, considering other aspects such as time, wear and tear, and fuel consumption, according to some embodiments.

[017]Other advantages and other new features are presented in the detailed description of the invention below.

DETAILED DESCRIPTION OF THE INVENTION

[029] The invention is defined as a process and a system, which can be understood in one of the embodiments described below. This invention may, however, be conducted in many different forms and should not be considered limited to the embodiments described in this specification, which are rather intended to detail and illustrate different aspects of the invention.

[030]Other aspects and characteristics of the invention may be evident from the detailed description presented below, when considered in conjunction with the attached figures. The figures are not, however, to be considered as examples of the various embodiments of the invention and are not to be considered as limiting the invention, which is limited only by the appended claims. Furthermore, the figures are not necessarily drawn to scale and are, unless otherwise indicated, intended to conceptually illustrate aspects of the invention.

[031] Figure 2 shows a vehicle 200, adapted for load transfer by a three wheel truck. Vehicle 200 has a front wheeled wheel 210, and a rear truck 220, consisting of a first wheel drive 230-1, a second wheel drive 230-2, and a support wheel 230-3. Vehicle 200 is arranged to travel forward in a direction of travel 240. The terms front and rear refer, in this context, to the direction of travel of vehicle 240.

[032] The assembly of bogie 220 on vehicle 200, which is described above, i.e. a three wheel bogie, is merely an example. Vehicle 200 may be, for example, equipped with several front wheel wheels 210. Furthermore, vehicle 200 may have a rear bogie 220, consisting of any number of wheels 230-1, 230-2, 230-3 in some embodiments, such as two, three, four, five, six, ..., ~, etc. The rear bogie wheel can also comprise any combination of 230-1, 230-2 traction wheels and 230-3 support wheels in different embodiments. For example, all wheelsets 230-1, 230-2, 230-3 in bogie 220 may consist of drive wheelsets 230-1, 230-2 in certain embodiments. In other embodiments, all of the 230-1, 230-2, 230-3 wheelsets on load transfer 220, except one of them, may consist of 230-3 support wheelsets. This can also be expressed as: n = k + i , where n > 1 and k > 0,

[033]where: n = number of wheelsets on bogie 220, k = number of traction wheelsets 230-1, 230-2 and i = number of support wheelsets 230-3.

[034] In some embodiments, the wheelsets 230-1, 230-2, 230-3 on bogie 220 can be suspended on suspension devices, at least some of which have an elastic installation with adjustable stiffness. In this way, the pressure can be distributed between the wheelsets 230-1, 230-2, 230-3.

[035] In some embodiments, the elastic installation may be pneumatically or hydraulically maneuverable, comprising, for example, an air suspension including an air source and a control valve to regulate the air supply.

[036]The vehicle 200, or also its driver instead, may sometimes need the load weight to be distributed across all wheelsets 230-1, 230-2, 230-3 on bogie 220. Thus, it is It is possible to maximize the magnitude of the payload, as the load weight can thus be distributed over all three wheel wheels 230-1, 230-2, 230-3. An example of this will be illustrated below and discussed in conjunction with the description of Figures 3A and 3B.

[037]However, the vehicle driver may, for example, when driving on a slippery surface, prefer a load transfer from the 230-1 front wheel drive wheel to the 230-2 rear wheel drive wheel, as illustrated and discussed in conjunction with the description of Figures 4A and 4B. For vehicles 200 driven on a slippery surface it may, in certain cases, it may be preferable to just unload the support wheel 230-3 and transfer this weight to the drive wheels 230-1, 230-2 for accessibility reasons. The support wheel 230-3 can also continue to roll on the running surface, but with a reduced or zero load; alternatively, the support wheel 230-3 can be lifted.

[038] However, to optimize the tilt radius it may be necessary to have a wheel base as short as possible, especially for vehicles 200 driven on a narrow roadway and/or to avoid unnecessary deterioration of the roadway. It is therefore advantageous and desirable to conduct a load transfer from the support wheel 230-3 and the rear wheel drive wheel 230-2 to the front wheel drive wheel 230-1, as illustrated in Figures 5A and 5B.

[039]With this type of load transfer, the tilt radius is improved, but vehicle 200 stability and accessibility on a slippery surface are significantly worse than when using the 230-2 rear wheel. Also, in this alternative, the support wheel 230-3 may also continue to roll on the running surface, but with reduced or zero load; alternatively, the support wheel 230-3 can be lifted.

[040] The present invention also relates to configurations in which in addition to the support wheel 230-3 can be lifted, also the traction wheel of the truck 230-1 can be lifted. Through this configuration, the 230-3 liftable support wheel and 230-1 liftable traction wheel configurations are obtained, and these load transfers can be conducted between the 230-1, 230-2 wheelset and 230-3. This results in more possibilities or combinations of the load transfer function as the wheel base and its tilt radius can be adapted to the driving conditions. For an example where if load transfers are conducted from the 230-1 front wheel drive wheel to the 230-2 rear wheel drive wheel, and the 230-1 front wheel drive wheel is raised, then the pressure on the 230-rear wheel drive wheel 2 is increased, and thus a longer wheelbase is achieved and better stability also in regular highway driving. It is not necessary to lift the wheelsets (230-1 and/or 230-3) to obtain a better inclination radius, it may be enough to transfer the load from any of them to the mechanical drive axle 230-02, and if so possible, also lift the 230-01 and/or the 230-13.

[041] It is not uncommon that all of these different configurations, illustrated in Figures 3 - 5 of wheelsets 230-1, 230-2, 230-3 on bogie 220, are required on one and the same vehicle 200. An example of this vehicle 200 is that of dairy trucks. To avoid unnecessary wear and tear on the apron and to additionally be able to rotate as little as possible, it is advantageous that vehicle 220, when moving through a apron, is able to select a transfer wheel loader to the front wheel drive 2301 in the bogie of vehicle 220. Other examples of vehicles 200, which can benefit from having a reduced tilt radius, are vehicles 200 that need to be driven in narrow spaces, such as a garage; emergency vehicles, such as fire trucks and the like, that need to move close to a fire, and forest vehicles that need to move between trees, etc.

[042] However, during road transport, it may be preferable to otherwise drive the vehicle 200 with a load shift to the 230-2 rear wheel drive, in particular in slippery road conditions. day for improved control, stability and traction.

[043] When vehicle 200 needs to collect a load, for example, milk, in case vehicle 200 is in a dairy truck, it may be advantageous to distribute the load across all the various wheelset, or even across all the wheelset of wheels 230-1, 230-2, 230-3 on bogie 220.

[044] Activation of the function can be resolved with a control 300, for example, in the form of, or comprising, a 310 cable or a three-position switch, which allows the driver the ability to select between the various trans- load transfers, in some embodiments, which is illustrated in Figures 3B, 4B and 5B.

[045]The design of this control 300, in the figures, should only be considered as an example design. For example, the control 300 can be equipped with an indicator for different alternatives, such as "small tilt radius required", "heavy load" and/or "highway", or similar texts. Furthermore, the control 300 can be designed as a switch, multiple compression buttons, a cursor, a software button or similar.

[046] In this way, the driver receives the ability to adjust the vehicle's load transfer to the driving situation, lane condition and load, which leads to an optimized vehicle 200 with a con- improved duction, in particular, in situations where a small tilt radius is advantageous.

[047] Figure 6 illustrates an example of an embodiment for the invention. The flowchart illustrates, in Figure 6, a process 600 for controlling load transfers in a vehicle 200, comprising a bogie 220 with at least one front wheel 230-1 and one rear wheel 230-2. Boom 220 may comprise at least two traction wheels 230-1, 230-2 and at least one support wheel 230-3, in certain embodiments. Trick 220 can comprise a three-wheel trick, a four-way trick, a five-fold trick, a six-fold trick, a seven-fold trick, an eight-fold trick and/or a nine-fold trick, etc. in different embodiments.

[048] To regulate the load transfer to vehicle 200 correctly, process 600 may comprise several steps 601 - 605. However, it should be noted that certain parts of the steps described in this specification are only understood in some alternative embodiments of the invention. Furthermore, the steps 601 - 605 described in this descriptive report can be carried out in a chronological order somewhat different than that suggested by the numbering, and some of these can be completed in parallel with each other. Process 600 comprises the steps presented below.

Step 601The vehicle's driving condition is determined.

[049] This determined driving condition, which can be the existing or necessary condition, may comprise: a reduced inclination radius, improved traction and control characteristics, and/or load maximization. This driving condition can be confirmed or determined by the driver of the vehicle. The driver can, based on prevailing environmental conditions and/or information relating to the vehicle, determine said driving conditions. Environmental conditions include what the driver considers as a current running track condition, geographical position and/or environmental conditions. But the driver can also consider information relating to the vehicle, such as vehicle load and/or vehicle driving behavior. With the driving behavior of the vehicle, it is, for an example referred to it, if the vehicle leans or if there is a different handbrake on different wheels or instabilities in the traction wheel. The determination is made in conjunction with driving the vehicle and based on information relating to the vehicle. In this way, the adjustment of load transfers can be made based on the condition of the current runningway, geographic position, environmental condition, but also based on information about the driving behavior of the vehicle and/or the vehicle load. In certain driving situations, it may be advantageous to distribute load to the various wheelsets, or even to all wheelsets in the truck, to maximize the magnitude of the payload.

[050] In an alternative embodiment, the driver is informed of the prevailing environmental conditions and/or information relating to the vehicle through the communication module 740, and the driver can thereby determine the driving condition of the vehicle. Communication module 740 is adapted to receive environmental signals from control device 710, representing prevailing environmental conditions, but also vehicle-related information, such as vehicle load information and behavior information. driving the vehicle. The environmental signs (not shown in the figure) represent, for example, information regarding the friction between the vehicle and the running surface, the geographical position obtained by means of a positioning system, and/or the environmental conditions predominant. Control device 710 receives data from the vehicle's internal systems and sensors to generate the environmental signals and information relating to the vehicle. Examples of internal systems and vehicle sensors are tilt sensors, gyroscopes, accelerometers, wheel angle sensors, yaw rate sensors, but also information, for example, from the braking system and the system of stability can be used. Based on information relating to prevailing environmental conditions and information relating to the vehicle, the driver can determine the vehicle's driving conditions, and thus the regulation of load transfer can be done.

Step 602

[051] A load transfer configuration for vehicle 200 is determined, based on the determined driving condition 601 for the vehicle, by setting a driver commanded control 300 to select a transfer configuration of cargo. In this way, the load transfer configuration for vehicle 200 is determined based on the driving conditions that the driver has determined. If the driver assumes that he will drive the vehicle in a physical environment with slippery rolling conditions, then he selects to regulate, through a driver commanded control 300, the load transfer function that is best suited to the environmental conditions predominant for this case of slippery running conditions.

[052] The driver-controlled control 300, which is adjustable in a load transfer configuration, comprises: a load distribution across all wheelsets 230-1, 230-2, included in bogie 220, transfer load transfer to rear wheel 230-2 on truck 220, and load transfer to front wheel 230-1 on truck 220.

[053]Determining the load transfer setting can be made so that load transfer to front wheel 230-1 on bogie 220 can be done when the driver wants a smaller lean radius. Furthermore, load transfer to the 230-2 rear wheel on bogie 220 can be done when the driver desires improved traction and control characteristics. Load distribution can also be done on all wheelsets 230-1, 230-2 included in bogie 220, when load maximization is desired, according to some embodiments.

Step 603

[054] A control signal is generated in a control device 710, which can be effected by the driver commanded control 300, to regulate the load transfer setting according to regulation 602, made by the driver commanded control 300.

[055]The adjustment of load transfer from a first load transfer configuration, in which the load distribution is made on all wheelsets 230-1, 230-2, 230-3 included in bogie 220, for either the front wheel 230-1 or the rear wheel 230-2 on bogie 220, according to some embodiments. This adjustment of load transfer can be initiated with a load transfer from the 230-3 support wheelset to the 230-1, 230-2 traction wheelsets, according to some embodiments.

Step 604

[056]The generated control signal 603 is sent from the control device 710 to a control mechanism 720, for the charge transfers introduced in conjunction with the bogie 220.

[057] This control signal may be sent over an interface, which may consist of a wireless interface in some embodiments, but may consist of a wired interface. The wireless interface can consist of a radio transmitter, based on wireless communication technology such as a 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE), LTE-Advanced, Access Network by Evolved Universal Terrestrial Radio (R-UTRAN), Universal Mobile Telecommunications System (UMTS), Global System for Mobile Communications/GSM Evolution Optimized Data Rate (GSM/EDGE), Broadband Code Division Multiple Access (WCDMA) ), Worldwide Interoperability for Microwave Access (WiMax), Wireless Local Area Network (WLAN), Mobile Ultra Broadband (UMB), Bluetooth (BT) or an infrared transmitter, mentioned in this report as a few examples wireless communication.

[058] In some embodiments, communication may be over a communication bus. This communication bus can be arranged for connecting various electronic control devices (ECUs) or electronic controllers, and different components arranged in the vehicle 200.

Step 605

[059]The load transfer in bogie 220 is regulated by means of control mechanism 720, according to setting 602 made by driver commanded control 300.

[060] Figure 7 illustrates an embodiment of a system 700 in a vehicle 200, which system 700 comprises a bogie 220, with at least one front wheel 230-1 and a rear wheel 230-2, to adjust the transfer of load on the vehicle 200. The bogie 220 comprises at least two traction wheels 230-1, 230-2 and at least one support wheel 230-3.

[061] System 700 comprises a driver-driven control 300 for selecting a load transfer setting based on the vehicle's determined driving condition.

Communication module 740 is, according to one embodiment, adapted to receive environmental signals and/or vehicle-related information from control device 710 representing prevailing environmental conditions and vehicle-related information. Control device 710 receives data from the vehicle's internal systems and sensors so that it is capable of generating environmental signals and vehicle-related information.

Process (600) for regulating load transfers to a vehicle (200), comprising a bogie (220) with at least a front wheel axle (230-1) and a rear wheel axle (230-2) and at least minus one support wheel axle (230-3), CHARACTERIZED in that it comprises: confirmation (601) by the driver of the driving condition of the vehicle; determination (602) of a load transfer configuration for the vehicle (200), on the basis of in the confirmed driving conditions (601) for the vehicle, by adjusting a driver-controlled control (300) for selecting a load transfer setting; generating (603) a control signal in a device control (710), which can be influenced by the driver-controlled control (300), to adjust the load transfer setting according to the setting (602) made by the driver-controlled control (300); sending (604 ) of the control signal (603) generated from the control device (710) to a control mechanism control (720) for load transfers introduced together with the bogie (220); eregulation (605) of the load transfer in the bogie (220) by means of the control mechanism (720), according to the adjustment (602) made by the control commanded by the driver (300), in which the determination ( 602) of the load transfer configuration is done, so that:- the load transfer to the front wheel axle (230-1) on the bogie (220) is done when the driver decides that there are driving conditions with a small tilt radius;- load transfers to the rear wheel axle (230-2) on the bogie (220) are made when the driver decides that there are driving conditions with good stability; and - load distribution is made to all wheel axles (230-1, 230-2, 2303) included in the bogie (220), when the driver decides that there are load-maximizing driving conditions. 2. Process (600), according to claim 1, CHARACTERIZED by the fact that the load transfer of a load transfer configuration, in which the load distribution is made to all wheel axles (230-1, 230-2, 230-3) comprised in the bogie (220), begins with the load transfer being made from the support wheel axle (230-3) to the drive wheel axle (230-1, 2302). 3. System (700) on a vehicle (200) for regulating load transfers to a vehicle (200), comprising a bogie (220) with at least one front wheel axle (230-1) and one rear wheel axle (230-2) and at least one support wheel axle (230-3), CHARACTERIZED by comprising: a driver-controlled control (300) for the selection of a driver-based load transfer configuration , in the driving condition determined for the vehicle, in which, through the driver, it has been decided that the driving conditions comprise the following driving conditions: small tilt radius, good stability and load maximization; a control device ( 710), which can be adapted to generate and send a control signal in response to a driver-driven control signal (300); and a control mechanism (720), adapted to receive the control signal and adjust the load transfer to the bogie (220), according to the adjustment made by the driver commanded control (300), so that:- the transfer load for the front wheel axle (230-1) on the bogie (220) is made when the driver decides that driving conditions with a small tilt radius exist; - load transfers to the rear axle (230-2) in the bogie (220) are made when the driver decides that there are driving conditions with good stability; and - the load distribution is made to all wheel axles (230-1, 230-2, 2303) included in the bogie (220), when the driver decides that there are driving conditions with load maximization. 4. System (700), according to claim 3, CHARACTERIZED by the fact that the system (700) is arranged to conduct load transfer of a load transfer configuration, in which the load distribution is made to all. of the wheel axles (230-1, 230-2, 230-3) included in the truck (220), to either the front axle (230-1) or the rear axle (230-2) in the bogie (220), it starts with the load transfer being made from the support wheel axle (230-3) to the drive wheel axles (230-1, 230-2). 5. Vehicle (200), CHARACTERIZED by the fact that it comprises the system (700), as defined in claim 3 or 4. 6. Computer program for the regulation of load transfers to a vehicle (200), comprising a bogie (220) with at least one front wheel axle (230-1) and one rear wheel axle (230-2) and at least one support wheel axle (230-3), CHARACTERIZED by the fact that the process (600), as defined in claim 1 or 2, is conducted when a computer program is executed on a processor circuit (730) in a control device (710).
