ABSTRACT:
A wheel hub clutch assembly which includes a body attached to a wheel hub, an inner sleeve contained within the body and fixed to a driveable axle, a clutch member splined to the sleeve to be maintained in its disengaged position during operation for two-wheel drive and to be engaged with the body in clutching operation to couple the wheel hub to the axle for four-wheel drive, a cam ring formed at one side thereof with a cam face and rotatable on the sleeve, a cam follower splined to the sleeve and oepratively connected with the clutch member, the cam follower being loaded toward the cam ring to cooperate with the cam face so as to move the clutch member to its engaged position in response to rotation of the sleeve, a brake assembly for applying the brake to the cam ring by engagement therewith in response to rotation of the cam follower, and a slide ring rotatably coupled over the cam ring and associated with the cam follower and brake assembly for releasing the brake by engagement with the brake assembly when rotated by engagement with the cam follower. The cam face of the cam ring reliably disengages the cam ring from the brake assembly by engagement with the cam follower in clutching operation.
