A vehicle suspension comprising first and second arms mountable to a vehicle frame for vertical swinging movement adjacent opposite sides of the vehicle frame, each of which mounts an axle for rotatably supporting at least one ground-engaging wheel thereon. Air springs are mounted between the arms and the frame in load-transmitting relation therebetween. An improved axle lift mechanism for lifting the axles and the at least one wheel responsive to relief of air pressure in the air springs is provided which comprises first and second telescoping guide members mountable to the frame, each of which have a distal end adapted to be positioned adjacent opposing sides of the frame and being movable between a retracted position and an extended position. A first lever mechanism is adapted to be mounted to the frame, and is mounted to the distal end of the first telescoping guide member and to the first arm. A second lever mechanism is adapted to be mounted to the frame, and is mounted to the distal end of the second telescoping guide member and to the second arm. The arms are raised with respect to the frame when the first and second telescoping guide members move between the extended and the retracted positions. A spring is mounted to the first and second telescoping guide member to bias the first and second telescoping guide members into the retracted position.

[ The embodiments for which an exclusive property or privilege is claimed are defined as follows:] [1.] A vehicle suspension comprising first and second arms mountable to a vehicle frame for vertical swinging movement adjacent opposite sides of the vehicle frame, each arm mounting an axle for rotatably supporting at least one ground-engaging wheel thereon, and air springs mounted to the arms and mountable to the frame in load-transmitting relation between the arms and the frame, an improved axle lift mechanism for lifting the axle and the at least one wheel responsive to relief of air pressure in the air springs which comprises:first and second telescoping guide members mountable to the frame transverse to a longitudinal axis of the frame, each of the first and second telescoping members having a distal end adapted to be positioned adjacent one of the opposite sides of the frame, the first and second telescoping members being axially movable with respect to each other between a retracted position and an extended position;a first lever mechanism adapted to be pivotally mounted to the frame, and mounted to the distal end of the first telescoping guide member and to the first arm;a second lever mechanism adapted to be pivotally mounted to the frame, and mounted to the distal end of the second telescoping guide member and to the second arm;wherein the arms are raised with respect to the frame when the first and second telescoping guide members move from the extended to the retracted positions; anda spring mounted between the first telescoping guide member and the second telescoping guide member to bias the first and second telescoping guide members into the retracted position.
