The vehicle includes a suspended running chassis ( ) making it possible to define a longitudinal and vertical plane forming a reference on the chassis ( ), the preferred running direction being parallel to the longitudinal plane, and at least two wheel connecting systems, the wheels ( ) of which are not aligned relative to the longitudinal plane, the wheel connecting systems being mounted on the chassis ( ) on either side of the latter in the transverse direction, each of the wheel connecting systems including a wheel ( ) mounted on a support ( ) by means of a suspension device allowing vertical deflection of the wheel ( ) relative to the support ( ), the suspensions being independent of one another. Each support ( ) is mounted on the chassis ( ) by means of a camber mechanism which includes a camber lever ( ) and an actuating lever ( ) making it possible to vary the camber angle of the corresponding wheel ( ). The camber mechanism includes an arm ( ) mounted on the support ( ) on an axis of support oriented substantially parallel to the longitudinal plane, and mounted on the chassis ( ) without any possibility of tilting about a longitudinal axis relative to the chassis ( ), so as to transmit the weight carried by the chassis to the support ( ).

Vehicle suspension having active camber variation

A ground contact system for a vehicle having a wheel mounted on a wheel carrier, the wheel carrier being mounted on a support by a vertical suspension device, the support being mounted on a chassis by a load transfer arm on one side of which the support is articulated along an essentially horizontal geometrical camber axis, the load transfer arm being connected at its other side to the chassis along an essentially vertical geometrical axis, a camber control rod being pivotally mounted to the support some distance from the geometrical camber axis, the camber control rod being able to move transversely relative to the chassis, a triangulation-forming element connecting the load transfer arm to the chassis around the essentially vertical geometrical axis, such that it controls the moment about the essentially vertical geometrical axis.

Vehicle having suspension system with variable camber and vertical suspension in the plane of the wheel

The vehicle having a chassis extending towards the front end of the vehicle where it has an impact zone and a cabin for the transport of passengers. The vehicle embodies a mechanical device for raising at least the front of the cabin relative to the chassis while the cabin moves forwards relative to the chassis in the event of an impact, the mechanical device including at least one rocker articulated to the chassis on the one hand, and articulated to the cabin on the other hand.

Vehicle embodying a system for protection in case of impact

The vehicle includes a suspended running chassis ( ) making it possible to define a longitudinal and vertical plane forming a reference on the chassis ( ), the preferred running direction being parallel to the longitudinal plane, and at least two wheel connecting systems, the wheels ( ) of which are not aligned relative to the longitudinal plane, the wheel connecting systems being mounted on the chassis ( ) on either side of the latter in the transverse direction, each of the wheel connecting systems including a wheel ( ) mounted on a support ( ) by means of a suspension device allowing vertical deflection of the wheel ( ) relative to the support ( ), the suspensions being independent of one another. Each support ( ) is mounted on the chassis ( ) by means of a camber mechanism which includes a camber lever ( ) and an activating lever ( ) making it possible to vary the camber angle of the corresponding wheel ( ). The camber mechanism includes an arm ( ) mounted on the support ( ) on an axis of support oriented substantially parallel to the longitudinal plane, and mounted on the chassis ( ) without any possibility of tilting about a longitudinal axis relative to the chassis ( ), so as to transmit the weight carried by the chassis to the support ( ).

The vehicle includes a suspended running chassis (,) making it possible to define a longitudinal and vertical plane forming a reference on the chassis (,), the preferred running direction being parallel to the longitudinal plane, and at least two wheel connecting systems, the wheels (,) of which are not aligned relative to the longitudinal plane, the wheel connecting systems being mounted on the chassis (,) on either side of the latter in the transverse direction, each of the wheel connecting systems including a wheel (,) mounted on a support (,) by means of a suspension device allowing vertical deflection of the wheel (,) relative to the support (,), the suspensions being independent of one another. Each support (,) is mounted on the chassis (,) by means of a camber mechanism which includes a camber lever (,) and an actuating lever (,) making it possible to vary the camber angle of the corresponding wheel (,). The camber mechanism includes an arm (,) mounted on the support (,) an axis of support oriented substantially parallel to the longitudinal plane, and mounted on the chassis (,) without any possibility of tilting about a longitudinal axis relative to the chassis (,), so as to transmit the weight carried by the chassis to the support (,).

A wheel connecting assembly for an automobile which includes a wheel carrier and a support having a guide member for guiding the wheel carrier in translational movement relative to the support. The support has journals for mounting the support on the chassis of a vehicle. The wheel carrier is mounted on the guide member by means of a bar sliding in the guide member. The assembly includes a spring and an electromechanical device capable of being operated in order to control the deflecting movements of the suspension.
