Constant velocity joint for use in universal shaft of motor vehicle, has lateral and middle lubricant gaps delimited by tapered radial distances between retainer guiding and appropriate opposite surfaces in axial direction of joint

摘要

The joint (1) has two lateral lubricant gaps (S1, S2) and a middle lubricant gap, which are formed between a retainer guiding surface (7) and an appropriate opposite surface (12) of a retainer (4). The gaps are delimited by local tapered radial distances between the retainer guiding surface and the appropriate opposite surface in an axial direction of the joint. The middle lubricant gap is arranged between the two lateral lubricant gaps that are tapered respectively in a direction of the middle gap.
