ABSTRACT:
A clutch release bearing wherein an annular wear plate is supported on the outer race structure of the bearing for limited displacement relative thereto by means of a resilient annular element. When the bearing is shifted axially of the clutch to uncouple driving and driven clutch members from each other, the wear plate contacts the release levers of the clutch at a location disposed radially displaced either inwardly or outwardly from the bulk of the resilient annular element. The bulk of the resilient annular element is also disposed axially between where it engages the annular wear plate and where it engages the outer race structure. In this way, the wear plate can assume a position wherein it generally uniformly engages all individual release levers of the clutch and with a minimum of relative movement occurring therebetween. Thus, the annular wear plate is considered self-aligning and provides a bearing construction which compensates for both out-of-square and eccentricity conditions which may exist. The annular wear plate may have an annular conical flange for engagement with the clutch release levers for increasing the tractive force between the clutch levers and wear plate which exists during conditions of eccentricity between the axis of the engine flywheel relative to the axis of the transmission input shaft.
