Abstract

Wheel Suspension System for a four-wheel vehicle, whereby each side of the vehicle is raised independently of the other side. Concurrently, the leverage ratio of the suspension of each wheel is modified according to the currently selected vehicle side height. Each wheel of the vehicle is elastically linked to the other wheel on the same side of the vehicle, in such a manner that, whenever the suspension of one wheel is compressed, the suspension of the other one tends to expand. In a more sophisticated version, each wheel is additionally linked in an elastic fashion to the wheel located diagonally on the opposite side of the vehicle, in such a manner that, whenever the suspension of a wheel is compressed, the suspension of the diagonally opposite one tends to get compressed, too. Auxiliary arm levers located between the wheels and the corresponding elastic units modify the leverage ratio between wheels and elastic units, in conjunction with the current position of the suspension of each wheel.

Claims

36AMENDED CLAIMS received by the International Bureau on 03 February 2006 (03.02.06)CLAIMS
1. Wheel Suspension System for a four-wheel vehicle comprising of longitudinal (2, 5) arms or transverse (52, 53) arms, or combination of longitudinal and transverse arms, each of which is articulated onto the body (100) of the vehicle and is linked to the corresponding wheel (3, 6) at its end or indirectly linked to the corresponding wheel through a rigid axle (39). Moreover, on each side of the vehicle, two of these four arms, one per wheel, are linked elastically with each other so that whenever a wheel is forced to move towards the vehicle body (100), the other wheel on the same vehicle side tends to move away from the vehicle body and this elastic linkage is performed through: two, one per side of the vehicle, carriers of axially deforming resilient elements (16), these carriers named Common Axially Flexible Units (15), through every one of which the suspensions of the two corresponding wheels of the same vehicle side are elastically interconnected, and each one of these Common Axially Flexible Units is connected to the rest of the Suspension
System in a floating manner enabling each one of its two linked ends (17, 18) to move in accordance to the motion of the corresponding wheel; rotating auxiliary arm levers (42, 43, 44), at least one per vehicle side, linked directly or indirectly with the corresponding Common Axially Flexible Unit (15) and one of the longitudinal (2, 5) arms or transverse (52, 53) arms through an appropriate linkage configuration consisting of pushing or pulling rods (41), resulting in a continuous differentiation between the magnitude of any minute displacement Δzi of the wheel moving towards the vehicle body and the magnitude of the corresponding minute displacement Δz2 of the other interconnected wheel at the same side of the vehicle, which is moving away from the vehicle body, when both of these wheels are in a distance from the ground and not in contact with it; two, one per side of the vehicle, variable length connecting members, named
Length Adjusting Devices (18), whose variable length is locally or remotely controlled, manually or automatically, and each one of the Length Adjusting Devices (18) is connected, directly or indirectly, in series with the corresponding Common Axially Flexible Unit (15), so that the controlled variation of the length in each one of the Length Adjusting Devices entails a controlled variation of the average distance between the body of the vehicle and the ground on the corresponding side and this Wheel Suspension System is characterized 37
by that when both wheels of the same side of the vehicle are not in contact with the ground and anyone of them is forced to move between points A1 and Bi for one wheel and, respectively, B2 and A2 for the other wheel, where A defines the maximum distance of a wheel from the vehicle body and B defines the minimum distance of a wheel from the vehicle body when this motion takes place without any further axial deformation of the corresponding Common Axially Flexible Unit (15), then the subsequent values of the function f=Δzi/Δz2, during the movement of one wheel from point Ai to point Bi and the simultaneous opposite movement of the other wheel from corresponding point B2 to corresponding point A2, are continuously decreasing, by that there is a point P in the path AiB1, between points Ai and B1, where the values of the function f=Δz-ι/Δz2 are bigger than 1 inside the path A1P and less than 1 inside the path PBi, and by that whenever the occasional length of the Length Adjusting Device (18) on one vehicle side ranges between two marginal values μ-i and μ2, then the increase of average distance between the ground and the vehicle body of the said side, caused by a certain length differentiation of the Length
Adjusting Device (18), entails a new position for the point P and a concurrent increase of both the average and maximum values of function f=Δz-i/Δz2, between points A-i and P, for the wheel moving towards the body of the vehicle.
2. Wheel Suspension System according to Claim 1 , characterized by that the increase, from hi to h2, of the average distance between the ground and the vehicle body, in any of its two sides, which is performed through a length differentiation of the corresponding Length Adjusting Device (18), entails a more compliant resilient behavior of the suspensions of the corresponding wheels of the certain side of the vehicle through a concurrent increase of the Combined Average Leverage Ratio (CALR) of both wheels, where CALR=(h3- h4)/ΔW, where h3 is an initial average distance of the vehicle body from the ground in this specific side, fu is a new, smaller, average distance from the ground after the appliance of an additional vertical load F on this side of the vehicle and ΔW is the work demanded for the corresponding axial deformation of the resilient element (16) incorporated in the Common Axially Flexible Unit (15) of this vehicle side, during this enforced movement of the vehicle body from its initial position h3 to the lower position h4.
3. Wheel Suspension System according to Claims 1 and 2, characterized by that the increase of the average distance between the ground and the vehicle body, at every side of the vehicle, is effected through the length increase of the corresponding Length Adjusting Device (18) in case it is connected, in series, with a Common Axially Flexible Unit (15) whose inner resilient element
(16) is compressed during the axial compression of the Common Axiaily Flexible Unit and by way of length decrease of the Length Adjusting Device (18) in case it is connected, in series, with the kind of Common Axially Flexible Unit, named Reverse Common Axially Flexible Unit (15A), whose inner resilient element (16) is compressed during the axial expansion of the Reverse Common Axially Flexible Unit.
4. Wheel Suspension System according to Claims 1 , 2, and 3, characterized by that the static load of the vehicle is counterbalanced exclusively by the forces produced from the axial compression of the elastic elements (16) incorporated in the two Common Axially Flexible Units (15) or the two
Reverse Common Axially Flexible Units (15A), consisting a self-balancing system under the static load of the vehicle where, for every wheel, whenever its distance from the vehicle body deviates from a certain value, then the forced opposite motion of the body portion which is above the other wheel at the same side of the vehicle, has such a magnitude so as to provoke an increase of the height of the gravity centre of the vehicle and a consequent self-stabilizing effect.
5. Wheel Suspension System, according to Claims 1 , 2 and 3, characterized by that in the case of an automatic length adjustment of the Length Adjusting
Device (18) of each side of the vehicle, this adjustment is performed through the processing of electric signals arriving to a processing unit from lateral acceleration sensors or vehicle body inclination sensors or a combination of lateral acceleration and inclination sensors.
