Description

Overland vehicle

Technical field

The invention belongs to overland vehicle, particularly be suitable for the overland vehicle that uses in cross-country locality specially.

Background technology

Continuous expansion along with the mankind's activity scope; Often need be deep into some cross-country locality and go work or life; So after automobile comes out soon; Just develop and some all-wheel powered cross-country cars (off-highway vehicle), so that utilize its whole adhesive ability to reduce the possibility of on muddy and slippery road surface, sliding and casting anchor because of wheel.This cross-country car is for the common vehicle of 4 * 2 drivings commonly used; Though the through performance on muddy and slippery road surface increases; But it can not reach the requirement that can go in most of cross-country locality far away, for example marshy area, soft seabeach or desert, water barrier, irrigation canals and ditches ...

In recent years, China is greatly developing green energy resource industry and marine industries, and a lot of areas all are in the location that existing cross-country car is difficult to turnover; Particularly China just builds several ten million multikilowatt wind power stations (field) in coastal beach area; Each wind energy turbine set all has nearly ten thousand wind power generating set, all needs the staff to keep in repair after building up, because beach is in the tidal effect area; The time and when water is arranged and be the beach, existing various cross-country cars all can not be born it and transport task; Existing water route amphibious vehicle is complex structure not only; Cost an arm and a leg; And under its tyre contact pressure height and the car outstanding driving axle housing (being commonly called as " tooth bag ") and draft hitch are arranged; Make it on soft surface, to be easy to sink, in case and overhang (for example " tooth bag ") contact to earth, its resistance to motion will increase suddenly and make it to skid and sink.Therefore, can make things convenient for, commute in time the work place in order to make the power station staff, be badly in need of developing a kind of overland vehicle, its principal feature is:

1) entry easily, water outlet, can resist certain stormy waves;

2) can on most of road surfaces that possibly run into, go for example soft road and marsh; Can cross over little irrigation canals and ditches ... Deng;

3) has the average velociity on higher waterborne and land;

4) simple in structure, cost is low, makes handy well.

Obviously; If this overland vehicle is succeeded in developing, it not only can satisfy the requirement of the exploitation of beach, and it can be used for landlocked various cross-country locality equally; For example desert, marsh, dense waterway net region, snowfield ... Deng, and a kind of actv. transportation means is provided for the developmental work in this type area.

Therefore, main purpose of the present invention is to develop a kind of cross-country traveling ability cross-country car that can satisfy above-mentioned requirements.

Summary of the invention

In order to reach the purpose of foregoing invention, the present invention has mainly taked following measures:

1) simplifies structure, to reach deadweight that alleviates vehicle and the purpose that reduces manufacturing cost as far as possible.For this reason, the design of cross-country traveling ability car of the present invention focuses on each item performance requriements when satisfying non-highway uses, in case of necessity, but proper longer some performance figure of on highway, going, for example maximum speed, ride comforts etc.

2) adopt the platybasic type vehicle underbody structure, i.e. hull shape or sled shape car bottom structure, and eliminate various projecting parts, to reduce the resistance that vehicle sinks to contacting to earth the back or in water, goes.

3) adopt the auxiliary drive that can increase propulsive effort, this device is after wheel sinks to a certain degree, to begin to contact with the road surface and can increase its tractive force significantly; Simultaneously, when in water, going, it can provide bigger thrust waterborne, and the speed of a ship or plane of vehicle in water greatly improved.Common this auxiliary drive is unwell on strong road surface and goes; When therefore designing; In the time of should making it on strong road surface; Leave suitable gap between its working portion and the ground, have only when vehicle at soft surface, just work in the time of for example in marshy area, sposh, loose dried sand ground and the water and after sinking to certain degree of depth.

4) adopt multi axle drive or endless track installation, make it to have lower ground pressure and the ability of crossing over little irrigation canals and ditches.

Concrete structure scheme of the present invention is:

1) adopting both sides is driving system and sliding (skid steering) steering swivel system of chain-type multi axle drive; Be that every limit is a string drive sprocket, each drive sprocket drives a drive wheels or crawler belt, and all drive sprockets on one side all fuse through chain gear; Make it to have identical rotating speed; Need only all driving crop rotation uniform movements that one of them drive sprocket is connected with axle drive shaft and can drives one side like this, promptly be equivalent to 4 * 4,6 * 6; 8 * 8,10 * 10 ... The multi axle drive form.Between two groups of chain-drivings axle drive shaft (drive axle that is equivalent to common vehicle) is being arranged about vehicle, diff is being arranged in the axle drive shaft and drive the chain drive system of the left and right sides through the output shaft on both sides respectively.Also have power-transfer clutch or drg on the output shaft on above-mentioned both sides and control the control of the rotating speed realization of two nearby vehicle (or crawler belt) travel direction through it.This structure can make a plurality of drivings " tooth bag " of traditional cross-country car reduce to one; Auxiliary gear box, transmission shaft have also been saved simultaneously; Like this; Its vehicle weight and productive costs are greatly descended, and it can also eliminate the main projecting part at the bottom of the car in addition, and resistance greatly reduces when making vehicle sink to contacting to earth or when in water, going.Adopt this driving system can also save suspension and steering track rod system, dead weight of vehicle further alleviated,, and eliminate the projecting part at the bottom of the car fully.

By the cross-country car that this programme is designed, its deadweight/load-carrying can be near 1: 1, and the cross-country car that adopts conventional confguration at the same level, this ratio is about 2～3: 1 (promptly from important big 1～2 times).The major defect of this scheme is that it has sacrificed some speed, ride comforts when on highway, going.Therefore, it is suitable for the basically whether go up various special vehicles that use in cross-country locality specially of road running, for example beach amph, dune buggy, marsh buggy, snow wagon ... Deng.

2) the car bottom structure of employing flat shape; Promptly make the car Bottom Shape of hull shape or sled shape and eliminate projecting part, except that drive wheel or crawler belt, have no prodger; Like this; Even vehicle on marsh, sposh, Song Sha, snowfield, go and sink to car at the bottom of bump when ground its resistance of taxing and can be reduced to minimum, as long as actuating device provides little propulsive effort, vehicle can continue to go.

3) adopt auxiliary blade to drive.Auxiliary blade wheel has identical installation dimension with all the other drive wheels, and can exchange installation, can install according to operating needs and a pair of or several blade taken turns.The blade external diameter of blade wheel should be more smaller than the external diameter of other drive wheel, and when making it on strong road surface, to go, blade does not contact with ground, thereby does not influence the riding comfort and the turning efficiency of vehicle.Can also improve the performance in the water through lengthening vehicle body, increase buoyancy if the blade wheel is loaded on the place ahead or the rear of vehicle.

4) through to whole-car parameters, about the choose reasonable and the coupling of the parameter of parts, give full play to each functions of components so that the average ground speed of vehicle in water and on the soft surface greatly improved.

Intending the overland vehicle scheme that several foundations concept design provided by the present invention of giving an example goes out below comes the present invention is further described.Should explain that these examples are just in order to make the reader be easier to understand the present invention, and can not be interpreted as that the present invention is limited within the embodiment.
