ABSTRACT:
A rotationally-dependent free-wheeling coupling for a motor vehicle comprises a first ring which constitutes a driving element in the towing mode of the motor vehicle, a second ring which constitutes a driven element in the towing mode, clamping elements which act between the first and second rings to transfer torque therebetween in both directions of torque flow, a cage which holds the clamping elements, and a friction element which causes the cage to rotate with the second ring. The rotationally-dependent free-wheeling coupling further comprises a latch which acts between the first ring and the cage, the latch being mounted for swiveling movement on an axle and entering a recess in the cage, the recess having a wall which constitutes a stop for the latch and defining a neutral (free-wheeling) position, a retaining spring which presses the latch into the recess of the cage, and a slipping spring. The slipping spring has a loop which is coiled around a fixed ring in a direction of rotation such that a protruding spring arm causes the latch to disengage from the recess in opposition to the force of the retaining spring when the vehicle is in reverse travel.
