<p>A disc and wheel bearing assembly of a driven wheel includes: a hub type brake disc integrally formed with a hub and a brake disc made of cast iron; a wheel bearing assembly comprising rolling elements, at least one inner ring installed in the rolling elements, a bearing inner ring shaft having a rolling shoulder portion on its one end and a spline portion on its other end, and an outer ring; a knuckle connected to the wheel bearing assembly; and a driving shaft having a spline portion and a male thread formed on its ends, wherein the male thread of the driving shaft is combined with the disc and wheel bearing assembly assembled to the knuckle by a nut and thereby, an axial force is given to the wheel bearing assembly so as to pre-load the wheel bearing assembly. The disc and wheel bearing assembly of a driven wheel constructed as above can simplify the structure of an axle assembly; thereby reduce weight and cost, by removing a hub function of a conventional axle assembly, giving a portion of the function to an inner ring shaft portion and disc and integrating the disc and a bearing.</p> |
