Drive wheel bearing assembly
First Claim
1. A drive wheel bearing assembly having a fixed type constant velocity universal joint, coupled to a wheel bearing, mounted to one end portion of an intermediate shaft, and a sliding type constant velocity universal joint, coupled to a differential, mounted to the other end portion of said intermediate shaft, wherein an allowable plunging down to a bottom portion of an outer joint ring of said sliding type constant velocity universal joint is set substantially equal to a sum of a width of an inner joint ring of said fixed type constant velocity universal joint and a length of a projection of the intermediate shaft beyond an edge surface of said inner joint ring, at a minimum operative angle of the sliding type constant velocity universal joint.

Abstract
In a drive wheel bearing assembly, a fixed type constant velocity universal joint is coupled to a wheel bearing, mounted to one end of an intermediate shaft, and a sliding type constant velocity universal joint, is coupled to a differential, mounted to the other end portion of the intermediate shaft. One end portion of a stub shaft is connected to an inner joint ring of the constant velocity universal joint via torque transmission portions; one end portion of the intermediate shaft is connected to the other end portion of the stub shaft via torque transmission portions. A threaded portion is formed on an outer diameter portion of either the intermediate or stub shaft; a nut member threadedly engages the threaded portion; and a keeper ring is fitted into annular grooves formed on the outer diameter portion of the intermediate shaft or the stub shaft and an inner diameter portion of the nut member allowing the nut member to rotate, but not move axially.

30. A drive wheel bearing assembly having a fixed type constant velocity universal joint, coupled to a wheel bearing, mounted to one end portion of an intermediate shaft, and a sliding type constant velocity universal joint, coupled to a differential, mounted to the other end portion of said intermediate shaft,
wherein an allowable plunging down to a bottom portion of an outer joint ring of said sliding type constant velocity universal joint is set to at least a width of an inner joint ring of said fixed type constant velocity universal joint at a minimum operative angle of the sliding type constant velocity universal joint, wherein a stem portion of an outer joint ring of said fixed type constant velocity universal joint is made hollow, and the hollow portion is allowed to communicate with a house portion of the outer joint ring, wherein an end cap is mounted to a communicating region between the hollow portion of said stem portion and said house portion, and a communicating portion is formed substantially at a center of the end cap.
