A planar overrunning coupling for transfer of torque from a driving member to a driven member in one direction and which permits freewheeling motion between the members upon a torque reversal, the coupling comprising coupling plates situated in close proximity with a strut retainer plate disposed between them, one plate being connected to the driving member and the other plate being connected to the driven member, each plate having strut recesses, a series of struts located in the recesses of one plate so that each strut may be pivoted, thereby allowing the struts to engage the companion recesses in the other coupling plate, the retainer having angularly spaced apertures that register with the struts to permit pivotal movement of the struts when the retainer plate is in one rotary position, the retainer plate, when it is in a second rotary position, preventing pivotal motion of the struts, thereby permitting freewheeling relative motion of the coupling plates.

Controllable overrunning coupling

A damper assembly for use with a transmission structure having at least two spline tooth spaces. The damper assembly comprises a torque transmission plate having at least a first and second spline situated to engage the at least two splined tooth spaces and a damper element located such that when the torque transmission plate engages the transmission structure, the damper element will be compressed between the first spline and one of the at least two splined tooth spaces before the second spline engages the other of the at least two spline spaces. Accordingly, the engagement of the second spline with the other of the at least two splined tooth spaces is dampened.
