ANTI-CREEP DEVICE FOR A TRAILER WITH AIR SPRINGS

摘要

An anti-creep device for a trailer includes a support arm (250) adapted to be mounted to a trailer frame (14) proximate to a trailer axle (16) for rotational movement between a retracted position and an extended position. The support arm (250) includes a plurality of notches (252) extending along a length thereof. A support member (236) is adapted to be connected to the suspension and has at least one surface for receiving one of the support arm notches (252) when the support arm is in the extended position to prevent movement of the axle (16) toward the trailer frame (14) and thereby prevent the trailer frame from creeping. The notches (252) of the support arm (250) in the retracted position are disengaged from the support member (236) so that the axle is free to move with respect to the frame. An actuator (80) is associated with the support arm for rotating the arm at least to the extended position to thereby lock the frame at a selected height when the frame is raised with respect to the axle.
