Abstract:
In an anti-creep device for a suspension having a pair of trailing arms with a first end rotatably mounted to opposite sides of a trailer frame, an air spring disposed between each trailing arm and the trailer frame to resiliently resist the upward movement of the trailing arms with respect to the frame, and an axle connected to the trailing arms, the axle having opposite ends adapted for mounting a wheel thereto, the anti-creep device comprising:a pair of support arms adapted to be mounted at opposite sides of the trailer frame for rotational movement between a retracted position and an extended position, the support arms in the extended position being adapted to abut the suspension at the opposite sides of the trailer frame to prevent movement of the axle toward the trailer frame and thereby prevent trailer frame creep, the support arms in the retracted position being disengageable from the suspension so that the axle is free to move with respect to the frame;an extension rod adapted to extend between the opposite sides of the frame, the pair of support arms being fixedly attached to opposite ends of the extension rod for rotational movement therewith; andan actuator operably connected to the extension rod and adapted to rotate the extension rod and thus the support arms between the retracted and extended positions; the improvement which comprises;a sensor switch adapted to be mounted to the frame in the vicinity of at least one of the support arms for sensing the position of the at least one support arm; and an indicator operably connected to the sensor for indicating when the at least one support arm is in the extended position.
