Problems solved by technology

However, in such a bearing device for a wheel, the hub bolts are pressed into the wheel mounting flange, and the heads of the hub bolts are in a state close to the outer member, so there is a problem that the replacement of the hub bolts cannot be performed if the height dimension of the weir portion is increased (see Figure 25 )

Embodiment Construction

[0081] Below, use Figure 1 to Figure 4 The wheel bearing device 1 of the present invention will be described. figure 1 It is a perspective view of the bearing device 1 such as a wheel. figure 2 of figure 1 A-A sectional view in . image 3 as well as Figure 4 yes figure 2 Enlarged view of a local area in .

[0082] The wheel bearing device 1 rotatably supports a wheel in a suspension device of an automobile or the like. The wheel bearing device 1 includes an outer member 2, an inner member 3 (a hub 4 and an inner ring 5), rolling elements 6, a seal member 7 (hereinafter referred to as "inner seal member 7"), and a seal member 10 (hereinafter referred to as "inner seal member 7"), and a seal member 10 (hereinafter referred to as " Outer sealing member 10"). Here, the inner side indicates the vehicle body side of the wheel bearing device 1 when mounted on the vehicle body, and the outer side indicates the wheel side of the wheel bearing device 1 when mounted on the v...

Abstract

A bearing device 1 for a vehicle wheel, wherein an annular weir part 20 is provided on the outer periphery of an outer-side end part of an outer member 2, the annular weir part 20 having the rotationaxis L of an inner member 3 as a center, the weir part 20 having a shape that is asymmetrical between the upper side Us and the lower side Ls of the outer member 2, and the weir part 20 being inclinedfarther toward the inner side the more a weir wall surface 20a faces outward in the radial direction in a part or all of the upper side Us. Also, the weir part 20 is inclined farther toward the outerside the more the weir wall surface 20a faces outward in the radial direction in a part or all of the lower side Ls.

Description

technical field [0001] The present invention relates to a bearing device for a wheel. Background technique [0002] Conventionally, a wheel bearing device that rotatably supports a wheel is known as a suspension device of an automobile or the like. In the wheel bearing device, an outer member is fixed to a knuckle constituting a suspension device. In addition, in the wheel bearing device, the inner member is arranged inside the outer member, and the rolling elements are interposed between the outer member and the inner member. In this way, the bearing device for a wheel constitutes a rolling bearing structure, and allows the wheel attached to the inner member to be rotatable. [0003] However, in such a bearing device for a wheel, when muddy water or dust enters the annular space formed between the outer member and the inner member, the rolling elements etc. are damaged and the life of the bearing is shortened. In addition, if the grease sealed in the annular space leaks ...
