ABSTRACT:
A drive assembly is provided including first and second torque input and torque output sections coupled together for relative rotation and limited relative displacement along the axis of relative rotation thereof. The input section includes structure for applying rotational torque thereto and the output section includes structure for applying rotary torque to a rotary driven member. Spring structure is connected between the sections yieldingly biasing the latter toward one set of limit positions of displacement along said axis and one of the units includes a spiral ramp concentric with the axis of relative rotation and the other of the sections includes a follower engaged with the ramp. The spiral ramp terminates at one end thereof in a circumferential race concentric with the axis of relative rotation of the sections and in which the follower is guidingly receivable for continuous movement therethrough after movement along the ramp from the end thereof remote from the race into the latter. The sections are displaced along the axis of relative rotation against the biasing action of the spring during movement of the follower along the ramp toward the race.
