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 opening of a clutch. The sleeve is attached to a clutch release bearing that is moved axially along the input shaft by a clutch fork. Engagement pads of the release fork engage rollers disposed on the clutch release bearing. The rollers on the clutch release bearing substantially eliminate transmission of non-axial force to the clutch release bearing and sleeve. The clutch release bearing includes an internal cavity in communication with a lubrication fitting. The rollers include hollow shafts in communication with the internal cavity of the clutch release bearing such that the lubricant injected into the internal cavity lubricates the rollers.
