Motor vehicle equipped with a system for controlling the camber of the wheels of the vehicle on a bend
First Claim
1. A motor vehicle having a system for controlling the camber of at least one pair of front or rear wheels of the vehicle running on a bend, said vehicle comprising:
- a body;
front and rear axles each having a pair of hub carriers, each hub carrier carrying one wheel of said pair of front or rear wheels of the vehicle; and
for each wheel of at least one of said front and rear axles, a suspension means for linking a corresponding one of said hub carriers to said body, each of said suspension means having a pair of suspension arms including an upper arm and a lower arm, each of said upper and lower arms having an outboard end articulated to said corresponding one of said hub carriers and an inboard end articulated to a pivot transfer lever, the inboard end of said upper arm being articulated at a first point of said pivot transfer lever and the inboard end of said lower arm being articulated at a second point of said pivot transfer lever located below said first point, said pivot transfer lever being mounted on said body by an articulation device defining an axis of rotation which extends in a longitudinal and vertical plane of the vehicle at a level below said second point of the pivot transfer lever, said pivot transfer lever being capable of pivoting about said axis of rotation in such a way as to incline the wheel carried by said corresponding one of said hub carriers toward a right or left side of the vehicle depending on whether the vehicle is running on a bend to the right or to the left.

Abstract
A motor vehicle fitted with a system for controlling the camber (θ) of the wheels of the vehicle on a bend, including, for each wheel of at least one front axle and/or rear axle of the vehicle, a suspension having a pair of suspension upper and lower arms, articulated at their outboard ends to a hub carrier and attached at their inboard ends to the body of the vehicle. The lower and upper arms of each pair are articulated at their respective inboard ends to a pivot transfer lever which is, in turn, mounted on the body by an articulation, the axis of rotation of which is contained in a longitudinal and vertical plane of the vehicle, the pivot transfer lever being capable of pivoting in such a way as to incline the wheels on the appropriate side.

18. A motor vehicle having a control system for controlling the camber of at least one pair of front or rear wheels of the vehicle running on a bend, said vehicle comprising:
-
a body;
front and rear axles each having a pair of hub carriers, each hub carrier carrying one wheel of said pair of front or rear wheels of the vehicle; and
for each wheel of at least one of said front and rear axles, a suspension means for linking a corresponding one of said hub carriers to said body, said suspension means having an outboard end articulated to said corresponding one of said hub carriers and an inboard end pivotally attached to said body;
wherein each suspension means is articulated to said body with a degree of freedom in rotation about an axis parallel to a longitudinal direction of the vehicle in order to vary the camber of the associated wheel;
wherein said suspension means inclines said associated wheel with respect to ground toward the inside of the bend under effect of a centrifugal force applied to said body; and
wherein each said suspension means has at least one suspension arm having an outboard end articulated to said corresponding one of said hub carriers and an inboard end articulated to a point of a pivot transfer lever, said pivot transfer lever being mounted on said body by an articulation device defining an axis of rotation which extends in a longitudinal and vertical plane of the vehicle at a level below said point of the pivot transfer lever, said pivot transfer lever being capable of pivoting about said axis of rotation in such a way as to incline the wheel carried by said corresponding one of said hub carriers toward a right or left side of the vehicle depending on the vehicle running on a right or left bend. - View Dependent Claims (19, 20)
