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.

A vehicle wheel suspension assembly capable of moving a vehicle wheel between a surface-engaging position and a retracted position, said assembly comprising: a support structure, bracket means for attaching said support structure to a vehicle, an arm for rotatably supporting a vehicle wheel, said arm being pivotally connected to said support structure to permit reciprocal movement of said arm in A generally vertical plane, resilient means supported by said support structure, and combined connecting and lifting means connecting the free end of said arm to said resilient means; said connecting and lifting means being movable between a first mode in which the vehicle wheel is in a surface-engaging position and a second mode in which said vehicle wheel is in a retracted position, said connecting and lifting means including a collapsible link connected between the free end of said arm and said resilient means which maintains a fixed distance of separation between the points of connection when said connecting and lifting means is in said first mode and causes a reduction in the distance of separation upon collapse when said connecting and lifting means is moved toward said second mode to move said arm toward resilient means and control means operatively connected to said collapsible link for selectively moving said connecting and lifting means between said first and second modes.
