Patent ID: 7963538

Claim:
A wheel suspension assembly adapted for the suspension of a rear wheel of a motor vehicle having a vehicle body and an engine-transmission assembly, the assembly defining a longitudinal direction adapted to be parallel with the normal driving direction of the motor vehicle and a vertical direction being perpendicular to the longitudinal direction (X) and adapted to be vertical when the motor vehicle is in a normal driving state, the suspension assembly comprising: a wheel spindle housing, adapted to support a wheel spindle on which the rear wheel is mountable and defining a wheel center, a frame structure adapted to be connected to the vehicle body or the engine-transmission assembly, a spring link extending between and connecting the frame structure and the wheel spindle housing, the spring link carrying a vehicle spring, a first control link and a second control link extending between and connecting the frame structure and the wheel spindle housing, wherein the first and second control links are operable to control the wheel spindle housing to maintain the rear wheel substantially in parallel with the longitudinal direction, a first camber link extending between and connecting the frame structure and the wheel spindle housing, and a second camber link extending between and connecting the frame structure and the wheel spindle housing, wherein the first camber link and the second camber link intersect each other seen in the vertical direction, wherein the spring link, the first and second control links and the first and second camber links have a topology defining an instantaneous center of motion, wherein the instantaneous center of motion is located at a position far outside the wheel and then in the rear of the wheel spindle, or far inside the wheel and then in front of the wheel spindle, and wherein the first control link and the spring link together form a virtual lower triangular link swingable about a lower swing axis, wherein the first camber link and the second camber link together form a virtual upper triangular link swingable about an upper swing axis, wherein the lower swing axis and the upper swing axis are approximately parallel with each other.
