Abstract
A wheel hub clutch assembly comprises a cylindrical body formed therein with a first set of clutch teeth and fastened to a wheel hub, a sleeve member fixed to the outer end of a drive axle and located within the body, a clutch member formed with a second set of clutch teeth and axially slidably mounted on the sleeve member for rotation therewith, a cam ring operatively coupled with the outer end of a stationary axle tube for the drive axle and rotatable on the sleeve member, a cam follower ring axially slidably mounted on the sleeve member for rotation therewith and cooperable with the cam ring to be displaced toward the clutch member in response to rotation of the drive axle, and a connecting member engaged with the cam follower ring and the clutch member to permit relatively inward movement between the cam follower ring and clutch member. The improvement comprises a first spring arranged between the cam follower ring and the clutch member for loading the cam follower ring toward the cam ring and cooperable with the connecting member for loading the clutch member for movement away from engagement with the first clutch teeth, and a second spring arranged in parallel with the first spring between the cam follower ring and the clutch member for loading the clutch member for movement toward engagement with the first clutch teeth.
