BEARING DEVICE FOR WHEEL, METHOD OF ASSEMBLING BEARING DEVICE FOR WHEEL, ASSEMBLY CONSTRUCTED FROM BEARING DEVICE FOR WHEEL AND FROM DRIVE SHAFT, AND METHOD OF ASSEMBLING ASSEMBLY |
摘要 |
The present invention provides a wheel bearing device, a method of assembling the wheel bearing device, an assembly configured by the wheel bearing device and a drive shaft, and a method of assembling the assembly, in which the wheel bearing device eliminates a nut tightening operation, is capable of reducing costs, and has a projection and recess mating structure that can firmly connect an outer joint member and a hub. Axial direction load is applied to a stepped surface 56 provided on an outer diameter surface of an outer joint member. A projection that extends in the axial direction and is provided on one of a stem shaft 9b of the outer joint member and an inner diameter surface of a hole section 29 of a hub 4 is press-fitted into a partner member along the axial direction, As a result, a recess that is in close contact with the projection over an overall mating contact area 45 is formed in the partner member, thereby configuring a projection and recess mating structure M. |
