Patent ID: 7845658

Claim:
A liftable suspension system for use on a vehicle, the suspension system comprising: first and second wheel spindles which support respective first and second wheels having respective first and second camber angles; first and second support devices, each of the first and second spindles extending outwardly relative to a respective one of the first and second support devices, and the first and second support devices being spaced apart in a lateral direction; first and second arms, each of the first and second support devices being pivotably connected to a respective one of the first and second arms, whereby each of the first and second arms is pivotable about a pivot orthogonal to the lateral direction, and each of the first and second arms being configured for pivotable connection to a frame of the vehicle; and an actuator which lifts at least the first support device relative to the vehicle frame when the suspension system is attached to the frame, the actuator applying a force to the first arm and an oppositely directed force to a bracket when the first device is lifted relative to the vehicle frame, and the actuator being pivotably connected to the first arm, wherein the first and second camber angles do not change when the first and second support devices are raised and lowered, and wherein the first and second support devices are displaceable relative to the vehicle frame independently of each other when the suspension system is attached to the frame.
