ABSTRACT:
A vehicle wheel suspension assembly capable of moving a vehicle wheel between a surface-engaging position and a retracted position wherein the assembly comprises a support structure, a connecting bracket for attaching the support structure to the undercarriage of the vehicle, an arm for rotatably supporting a vehicle wheel, the arm being pivotally connected to the support structure to permit reciprocal movement of the arm in a generally vertical plane, a resilient member supported by the support structure, and a combined connecting and lifting device connecting the arm to the resilient member; the device being movable between a first mode in which the vehicle wheel is in a surface-engaging position and the arm is rigidly connected to the resilient member and a second mode in which the vehicle wheel is in a retracted position, the device including a control mechanism for selectively moving the device between the first and second modes.
