Abstract
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.
Claims43
A wheel connecting assembly for an automobile, said assembly comprising a hub to support a wheel from a chassis of the automobile, said wheel including a disk defining a wheel plane perpendicular to the axis of rotation of the wheel and passing through the center of the area of contact with the ground of a tire mounted on said wheel, said wheel having a reference width (L.sub.R) and a reference diameter (.phi..sub.R), said assembly further comprising a wheel carrier defining an axis of rotation of the hub, a support having a guide member for guiding the wheel carrier in translational movement relative to the support, mounting means for mounting the support on the chassis, the wheel carrier being mounted on the guide member by means of a single elongate bar having two ends and sliding relative to and guided by the guide member so as to be fixed against rotation about the sliding axis, the wheel carrier being mounted on the bar at the two ends of the latter, said assembly further comprising means for supporting the automobile load transmitted by the support to the wheel carrier, wherein the wheel carrier, the bar and the guide member are accommodated in a limiting envelope defined radially by the reference diameter (.phi..sub.R) and axially, on one side, by a limit set by the disk of said wheel and, on the other side, by a virtual plane tangent to the wheel.
A wheel connecting assembly for an automobile, said assembly comprising a rotating hub designed to support a wheel, said wheel comprising a disk defining a wheel plane perpendicular to an axis of rotation of the hub and passing through the center of the footprint of a tire mounted on said wheel, said assembly comprising:
- a suspended support comprising mounting means designed to connect the support to the chassis of the automobile;
- a wheel carrier;
- a suspended guide member received on the support, the guide member and the support forming a pivot that allows a degree of freedom of steering of the wheel carrier relative to the support;
- a non-suspended single elongate bar sliding along an axis relative to and guided by the guide member so as to be non steerable with respect to the guide member about the sliding axis and to provide a suspension movement between the support and the wheel carrier along the sliding axis, said bar being received within the guide member;
- said wheel carrier being mounted on the bar at the two ends of the bar, the wheel carrier defining the axis of rotation of the hub;
- and
- spring means for supporting the automobile load transmitted by the support to the wheel carrier, said spring means acting between two bearing points, one of which is integral with the wheel carrier and the other of which is integral with the guiding member.
