    摘要： An axle assembly for drive wheels of vehicles includes a steering knuckle, an axle housing coupled to an inside of the steering knuckle, a wheel disc that is fixed to the axle housing to be rotatable integrally with the axle housing, and a drive shaft that is coupled to the axle housing to be rotatable integrally with the axle housing. A hub bearing is disposed between the steering knuckle and the axle housing. A forming part is formed at an end of the axle housing in a state in which a bearing inner race of the hub bearing is coupled to an outer circumferential surface of the axle housing, and the bearing inner race is engaged with a side part of the axle housing by the forming part in a state in which the forming part is pressed against a side end of the bearing inner race.

    摘要： A constant velocity joint for a vehicle. The constant velocity joint includes: an axle housing fixed to a knuckle by a hub bearing, and a joint assembly inserted into the axle housing to transmit power from a shaft to the axle housing through a plurality of joint balls. In particular, the axle housing includes an extension portion which is extended from an end portion of the axle housing in a radial direction of the axle housing, and the extension portion provides a pressing force to an inner race of the hub bearing in an axial direction of the axle housing. The constant velocity joint further includes a boot surrounding an outer side of the extension portion and coupled to the extension portion so as to form a restraining force between the extension portion and the boot in the axial direction.

    摘要： An axle assembly for a driving wheel of a vehicle allows a wheel-side joint and a shaft to be rotated separately from a boot while driving so as to prevent generation of friction noise of the boot. The axle assembly includes the shaft rotated by receiving driving force from a powertrain; an axle housing disposed to pass through a center of a steering knuckle connected to a steering apparatus; a wheel bearing mounted between the steering knuckle and the axle housing; a joint bearing mounted on an outer part of the shaft; and a boot unit configured to have a first end coupled to an outer race of the joint bearing and a second end coupled to an outer race of the wheel bearing so as to form a space filled with a lubricant outside the shaft.
