Abstract
A clutch assembly for a mobile vehicle clutch includes a sleeve axially disposed on a shaft and engaged to actuate clutch springs or levers for disengaging a clutch. The sleeve is attached to a clutch release bearing that is moved axially along the input shaft by a clutch fork. A contact surface of the release fork engages a contact surface disposed on lugs of the clutch release bearing. At least one of the contact surfaces includes a self-lubricating material to reduce friction between the release for and the clutch release bearing during actuation of the clutch assembly.
