Clamping element for drive unit pinion of internal combustion engine for motor vehicle, has clamping surface attached at drive unit in neutral position, and segments of needle bearing arranged directly at clamping surface

摘要

The element (6) has a inner surface (12) oriented towards a drive unit (4), where the element is rotatably supported around an rotational axle (11), which is arranged within a clamping element body. The inner surface comprises a clamping surface (13) that is convexly curved with respect to the rotation axle. The clamping surface is attached at the drive unit in a neutral position. Segments (23) e.g. roller bearings, of needle bearing are arranged directly at the clamping surface or arranged directly at a separate carrier element.
