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.
