Disclosed is a wheel bearing assembly comprising a wheel hub fastened to a vehicle wheel so as to rotate as a unit and having a plurality of fastening protrusion portions, and a brake disc having a plurality of fastening protrusion portions respectively fastened to the plurality of fastening protrusion portions of the wheel hub. Thus, the wheel bearing assembly may facilitate weight reduction and improvement in ease of assembly, and enhance run-out properties of sliding surfaces of the brake disc.

Wheel bearing assembly

The present invention relates to a structure and a method for coupling a wheel bearing that include a wheel hub for mounting a vehicle wheel, a hollow inner ring press-fitted into an end portion of the wheel hub, an annular outer ring disposed at a radial exterior of the wheel hub and the inner ring, and rolling elements disposed between the wheel hub or the inner ring and the outer ring, wherein the wheel hub and the inner ring are splined to each other and the inner ring and the joint member are coupled through facial spline. According to the present invention, driving torque of a constant velocity joint may be stably delivered to the wheel hub and noise may be reduced.

Structure and method for coupling wheel bearings

A wheel bearing assembly includes an outer race in which a plurality of rows of track portions are formed at an inner side thereof; a hub that is coaxially disposed with the outer race to be rotatably disposed in the outer race; an inner race that is engaged with a portion of an outside surface of the hub to rotate together with the hub; a first roller that is interposed between the hub and the outer race to be rolled; and a second roller that is interposed between the inner race and the outer race to be rolled.
