Abstract
A release assembly to a pull-type clutch releases the clutch by extracting the radially inward portion of a diaphragm spring in the direction toward an associated transmission. The release assembly comprises a release bearing and its retainer. The release bearing includes an outer race fixed onto the radially inward margin of the diaphragm spring and an inner race grooved by a concavity along its radially inward portion the focus of which coincides with the pivotal deviation center of the release assembly. A complementarily convex surface along the retainer slidably mates with the concavity of the inner race, allowing the retainer in this release assembly to be slidable along inner race of the release bearing. Accordingly, if the clutch and the transmission come into misalignment, the resultant slide of the retainer on the inner race of the release bearing compensates.
