Drive wheel for use as driving belt wheel on crankshaft for traction drive of internal combustion engine, has hub held in impeller, where contact surface is axially supported at impeller and made from wear-stable polymeric material

摘要

The wheel (1) has a hub (4) held in an impeller (5). An overrunning clutch allows relative twist of the impeller opposite to the hub in a rotation direction by lock bodies (6) i.e. pinch rolls, arranged between the impeller and the hub, and blocks the twist of the impeller in another direction. The clutch comprises an inner ring (2) that is secured at the hub. A face surface of a radial board (15) of the inner ring is fastened against a contact surface axially supported at the impeller, where the contact surface is made from wear-resistant polymeric material i.e. polyetheretherketone.
