Abstract: A clutch sleeve assembly for an automotive clutch system includes a polymer sleeve having a snap ring groove and a metal bushing disposed within the polymer sleeve having a flange that acts as a reinforcement for the snap ring groove. There are two configurations of the snap ring groove on the polymer sleeve. In the first configuration, the polymer sleeve has a notch around an outer circumference along its edge adjacent the bushing flange. In this configuration, the bushing flange extends beyond the polymer sleeve edge to form a snap ring groove in conjunction with the notch. In the second configuration, the polymer sleeve has a snap ring groove around its outer circumference spaced apart from its edge that is adjacent the bushing flange.

Abstract: A rider having a centralizing or radially stabilizing bushing that reduces vibration and a longitudinal stabilizer element or lip to prevent longitudinal translation of the stabilizing bushing. The centralizing bushing maintains contact, alignment, and general stability between the bushing and the shaft and reduces noise and fluctuations between the bushing and the shaft when they are moving relative to each other. The bushing is mounted in the rider and includes a bearing engagable with the shaft and a cap engagable with the longitudinal stabilizing unit. There are high friction, elastomeric means engagable with the bearing for limiting movement of the bearing away from the shaft and the rider is under unbalanced radial load conditions. The coefficient of thermal expansion of the bearing is essentially the same as the coefficient of thermal expansion of the shaft.
