Bearing device for drive wheel |
摘要 |
<p>The wheel hub 30 includes a radial swaged portion 37 formed by a radially outward plastic deformation of one end thereof, whereby an inner ring 40 fitted onto the wheel hub 30 is united therewith. An outer joint member 72 of a constant velocity joint 70 is press-fitted into the wheel hub 30, causing serrations 81 on the inner periphery of the wheel hub 30 and a serrated shaft 82 of the outer joint member 72 to engage with each other. The tooth profile of the serrations 81 on the wheel hub 30 is controlled within a predetermined specified range over the entire axial length thereof, whereby radial contraction of the serrations 81 caused by swaging is reduced. <IMAGE></p> |
