Embodiment Construction

[0026] Below, according to figure 1 , the first embodiment of the present invention will be described. figure 1 It is a longitudinal sectional view of the wheel bearing device according to the first embodiment.

[0027] figure 1 The illustrated bearing device for a wheel includes an inner shaft 1 , a rolling bearing 2 , and a coupling ring 3 .

[0028] The inner shaft 1 has: a shaft portion 11; a flange portion 12 formed on an outer end portion of the shaft portion 11, and the flange portion 12 extends radially outward; Cylindrical dimple portion 13 . A wheel (not shown) is fastened to the flange portion 12 with bolts 12a. A rolling bearing 2 for rotatably supporting the inner shaft 1 on an unillustrated suspension device of a vehicle body is mounted on an outer peripheral surface of an axially central portion of the shaft portion 11 . As the rolling bearing 2, a multi-row tapered roller bearing can be used. Multi-row tapered roller bearings are usually used to accept...

Abstract

The present invention provides a bearing device for a wheel which has a rolling bearing (2); an inner shaft (1), on the outer periphery of which an inner ring (24) of the rolling bearing (2) is installed; a coupler ring (3) fitted to an end of the inner shaft (1); and a staking part (15) formed at the end of the inner shaft (1) to fix the coupler ring (3) and the rolling bearing (2) to the inner shaft (1) in such a way that they cannot move in the axial direction of the inner shaft (1). The outer diameter dl of the coupler ring (3) is set smaller than the diameter d2 of the shoulder part (23c) of the inner ring (24). Alternatively, projection parts (231, 301) are formed on either of mutually facing end faces of both the coupler ring (3) and the inner ring (24), which causes the coupler ring (3) to be disposed away from a seal member (26). Consequently, interference between the coupler ring (3) and the seal member (26) is prevented.

Description

technical field [0001] The present invention relates to a wheel bearing device mainly used in vehicles such as automobiles. Background technique [0002] As a wheel bearing device for a part-time four-wheel drive (Part-Time 4WD) vehicle that can be switched between 2-wheel drive (2WD) mode and 4-wheel drive (4WD) mode, there is known a bearing device that can be connected to the engine The drive shaft (axle) of the drive shaft (axle) is selectively connected to the wheel or uncoupled, that is, selectively allows or cuts off the wheel bearing device from the drive shaft to the wheel (for example, refer to Patent Documents 1 and 2). [0003] In such a bearing device for a wheel, a rolling bearing for rotatably supporting the inner shaft on a suspension device of a vehicle body is mounted on the outer periphery of an inner shaft (hub shaft) on which a wheel is mounted. A center hole is provided at the center of the inner shaft, and a drive shaft is inserted into the center hol...
