WIPO Patent Application WO/2002/078979
Kind Code:
A1
Abstract:
A bearing device for drive wheel, wherein the end part of a hub wheel (30) is elastically deformed to the outer radial side to form a radial crimped part (37) to integrally form the hub wheel (30) with an inner wheel (40) fitted onto the outer periphery of the hub wheel, the outside joint member (72) of a constant velocity universal joint (70) is press-fitted to the inner periphery of the hub wheel (30) to fit serrations (81) on the inner periphery of the hub wheel (30) to the serration shaft part (82) of the outside joint member (72), and the tooth profile of the serrations (81) on the inner periphery of the hub wheel (30) is controlled within a specified range through the entire axial length thereof to suppress a reduction in diameter of the serrations (81) according to the crimping.
