Suspension system for a motor vehicle
First Claim
1. A vehicle suspension system for coupling a set of wheels to a vehicle body structure, the suspension system comprising:
- independently pivotable swing arms attached at one end to a vehicle body structure and at the other end to a respective wheel;
a joining arm arranged to be slidably moveable in a vehicle lengthwise direction and rotateable about an attachment point;
a shock absorber assembly mounted to a vehicle structure, the shock absorber assembly including a biasing element and a linkage coupled to the joining arm and the biasing element; and
a tie rod connecting each respective swing arm to the joining arm, wherein the joining arm is arranged to move in a vehicle lengthwise direction under control of the biasing element in response to road input to both wheels, and rotate without lengthwise movement to allow the tie rods to translate in opposite lengthwise direction in response to leaning of the vehicle.

Abstract
An independent suspension system is provided for coupling a set of wheels to a vehicle body structure. The system includes independently pivotable swing arms, a shock absorber assembly, a joining arm and tie rods. The swing arms are attached to the vehicle body structure and to a respective wheel and the shock absorber assembly is mounted to the vehicle structure. The shock absorber assembly includes a biasing element and a linkage coupled to the joining arm and the biasing element. The suspension system further includes a tie rod connecting each swing arm to the joining arm. The joining arm is arranged to move in a lengthwise vehicle direction under control of the biasing element in response to road input to both wheels, and rotate about an attachment point without lengthwise movement to allow the tie rods to translate in opposite lengthwise direction in response to leaning of the vehicle.
