Embodiment Construction

[0064] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0065] Figure 2 to Figure 6 A structure for coupling a wheel bearing according to a first exemplary embodiment of the present invention is shown.

[0066] Such as Figure 2 to Figure 6 As shown in , the structure for coupling wheel bearings according to the first exemplary embodiment of the present invention includes a hub 100 , an inner ring 200 , an outer ring 300 , rolling elements 400 , hollow pins 500 , joint members 600 and bolts 700 .

[0067] The hub 100 transmits driving torque of a joint member 600 such as a constant velocity joint (CVJ) to a vehicle wheel. The hub 100 is provided with a flange 101 and hub bolts 120 for mounting a vehicle wheel. Such as figure 2 As shown in , the flange 101 protrudes radially outward from the hub 100 and generally has a disc shape. A plurality of bolt holes are formed in the flange 101, ...

Abstract

The present invention relates to a structure and method for coupling a wheel bearing. The structure comprises: a wheel hub on which a vehicle wheel is mounted; a hollow inner wheel press-fitted into one side of the wheel hub; a ring-shaped outer wheel arranged outside the wheel hub and the inner wheel; and a rolling element interposed between the wheel hub or the inner wheel and the outer wheel. The wheel hub and the inner wheel are coupled together by a spline, and the inner wheel and a joint member are coupled together by a facial spline. According to the present invention, the driving force of a constant velocity joint can be stably transferred to the wheel hub, and noise can be reduced.

Description

technical field [0001] The present invention relates to a structure and method for coupling wheel bearings. More particularly, the present invention relates to a structure and method for coupling wheel bearings capable of improving the durability and quality of the wheel bearings. Background technique [0002] A wheel bearing used on an axle of a vehicle enables the vehicle wheel to rotate smoothly without friction loss and couples the vehicle wheel to the vehicle body. [0003] see figure 1 , figure 1 A cross-sectional view of a conventional vehicle bearing and a constant velocity joint assembled with each other is shown in . [0004] Such as figure 1 As shown in , a traditional wheel bearing includes a hub 4, an inner ring 3 press-fitted on the hub 4, an outer ring 5 arranged radially outside the inner ring 3, and a rolling mechanism provided between the inner ring 3 and the outer ring 5 element 2. In addition, a shaft of a constant velocity joint (CVJ) 6 is spline-c...
