PERFECCIONAMIENTOS EN LOS TOPES DE EMBRAGUE AUTOALINEADOS

摘要

A clutch release bearing assembly comprises a guide sleeve 16 having a cylindrical element 17 which surrounds a tubular guide 13 and by means of which the guide sleeve 16 can slide on the tubular guide with only a small frictional drag. The guide sleeve 16 also comprises a radially extending element 19 which is in contact with a radial flange 5 of an inner bearing ring 1 so as to guide the movement of the bearing in a radial plane. Resilient self-alignment of the assembly on the guide 13 is ensured by the provision of a number of ribs 18, which are an integral part of the cylindrical element 17 of the guide sleeve, and which are in contact with the bore of the inner bearing ring 1.
