Problems solved by technology

Therefore, the outer end surface of the outer joint member cannot be pressed against, and stable press-fitting is difficult.
In addition, when a pressing force is applied to the shaft end surface of the outer joint member of the outboard constant velocity universal joint, the area of ​​the pressing portion is small, the application of pressing force (pressing force) is unstable, and the pressing force is applied It will cause damage to the internal components (inner wheel, box body, ball) of the constant velocity universal joint

Embodiment Construction

[0077] Below, according to Figure 1 to Figure 10 Embodiments of the present invention will be described. figure 1 Indicates an assembly composed of a bearing device for a wheel and a drive shaft. The bearing device for a wheel has a constant velocity universal joint 1 on the outboard side, a constant velocity universal joint 2 on the inboard side, and these constant velocity universal joints 1 and 2 Connected axis 3. In this case, on the outboard side, the hub 4 , the plurality of rows of wheel bearings 5 ​​, and the constant velocity universal joint 1 are connected to form a wheel bearing device. The outside of the vehicle in the state of being assembled on a vehicle such as an automobile is called the outboard (left side of the drawing), and the inside of the vehicle in the state of being assembled on a vehicle such as an automobile is called the outboard (right side of the drawing). ).

[0078] Constant velocity universal joint 1 on the outboard side, such as figure ...

Abstract

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 outerjoint 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 isprovided 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.

Description

technical field [0001] The present invention relates to a bearing device for a wheel, a method for assembling the bearing device for a wheel, an assembly composed of a bearing device for a wheel and a drive shaft, and an assembly method for the assembly. Background technique [0002] transmits power from the engine to the drive shaft that drives the wheels, such as Figure 11 As shown, there is a fixed type constant velocity universal joint 104 on the outboard side (constituting the outside of the vehicle in the state assembled on the vehicle) and the outboard side (constituting the outside of the vehicle in the state assembled on the vehicle) by an intermediate shaft not shown in the figure. inside) with a sliding type constant velocity universal joint (not shown). A constant velocity universal joint 104 on the outboard side is coupled to a hub 102 rotatably supported by a wheel bearing device. [0003] The third-generation wheel bearing device is provided with: a hub 102 ...
