ABSTRACT:
An axle joint for connecting a removable tread member to the axle of a heavy vehicle. The tread member includes a window which provides ample clearance to loosely receive the end portion of an axle, which window and axle are then pivotally connected together by a pivot pin. A hydraulic cylinder is connected between the axle and the window and continuously applies a turning moment to the axle joint which firmly locks the axle within the window from relative movement in a vertical plane during operation of the vehicle.
