    摘要: A bearing device for a drive wheel is provided with improved strength of coupling a hub wheel and an outer joint member without significantly raising the manufacturing cost. The bearing device for a drive wheel includes the hub wheel, a constant velocity universal joint and bearings arranged in inner races, the hub wheel, the universal joint and the bearings being unitized, at least the inner race being formed in the outer joint member of the constant velocity universal joint. In the bearing device, the hub wheel and the outer joint member are meshed with each other by way of serrations and coupled to each other by caulking. Undulations of serrations at near a caulked section being filled with plastic deformed part caused by the caulking.

    摘要: Provided is a power transmission shaft to achieve enhancement of a static torsional strength of a smooth portion. The power transmission shaft according to the present invention includes a torque-transmission teeth portion (2) formed on an outer peripheral surface on an end portion side, and a smooth portion (3) formed on the outer peripheral surface adjacent to the torque-transmission teeth portion (2) so as to have a stepwise reduced diameter. A ratio of a minimum diameter (D3min) of the smooth portion (3) to a minimum diameter (D2min) of the torque-transmission teeth portion (2) is set to 0.9 or more and 1.02 or less. Further, the torque-transmission teeth portion (2) and the smooth portion (3) undergo heat treatment so as to from a heat-treated hardened layer (4). The heat-treated hardened layer (4) is formed to increase in depth from a side of the torque transmission teeth portion (2) to a side of the smooth portion (3). At least a minimum diameter portion (3a) of the smooth portion (3) undergoes full hardening for forming the heat-treated hardened layer (4) from a surface to an axis (X).

    摘要: A constant velocity joint assembly for a vehicle, having a fixed-type constant velocity joint linked at one end of a shaft portion of a vehicle and a plunging type constant velocity joint linked to the other end of the shaft portion. The fixed type constant velocity joint includes an outer joint member having eight curved guide grooves axially formed in the spherical inner surface and an inner joint member having eight curved guide grooves axially formed in the spherical outer surface. Serrations (or splines) are formed on the inner surface for connection to a shaft portion. Eight torque transmitting balls are disposed in ball tracks defined between the guide grooves of the outer and inner joint members. A cage retains the torque transmitting balls.
