Clutch bearing for friction clutch control in a car's IC engine includes a roller with oblique contacts so that when the axial load of the force is exerted on the external sleeve, it can move axially w.r.t the internal sleeve

摘要

The clutch release bearing includes a roller (21) having an internal sleeve (22) with arrangement for its coupling to declutching elements (9) of the clutch and an external sleeve (23) coupled to an interface unit (31) to be activated by this actuator, and adapted to exert on this interface, a traction force along the direction (T) axial to the rollers. The roller has oblique contacts, with the rolling elements (24) transmitting to the interior sleeve, the axial force of traction exerted on the external sleeve, by means of the interface unit, thus allowing an axial displacement of the external sleeve w.r.t the internal sleeve, when the axial load of the force is exerted on the external sleeve. An Independent claim is also included for the friction clutch using this type of clutch bearing.
