Embodiment Construction

[0076] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Fig. 1 shows a first embodiment of a bearing device for a wheel according to the present invention, (b) is a longitudinal sectional view, and (a) is a side view thereof.

[0077] This bearing device for a wheel has an inner member 1 , an outer member 10 and a plurality of rows of rolling bodies 20 , 20 . The inner part 1 is composed of a hub 2 and an inner wheel 3 . The inner ring 3 is press-fitted into a small-diameter stepped portion 4 formed at the inner end portion of the hub 2 . In addition, an inner inner rotational surface 3 a is formed on an inner inner rotational surface 2 a inside the outer circumference of the hub 2 and an inner inner rotational surface 3 a on the outer circumference of the inner ring 3 . In addition, a wheel mounting flange 5 for mounting a wheel (omitted in the figure) is integrally formed on the outer end of the hub 2, and ...

Abstract

The present invention provides a bearing device for a wheel in which the cross-sectional vibration accuracy of a side surface of a brake rotor of the bearing device for a wheel is improved. A bearing device for a wheel, in which a plurality of rows of rotating bodies (20) are stored between an inner part (1) and an outer part (10), and a rolling bearing for freely rotatably supporting a wheel is provided relative to a car body, and the inner part is constituted A wheel mounting flange (5) for fixing the wheel is formed on the wheel hub of (1). In addition, while an annular groove (7) having a predetermined width including hub bolts (6) is formed on the wheel mounting flange (5), the annular groove (7) is press-fitted after the hub bolts (6). The side (5a) of the wheel mounting flange (5) other than 7) is used as the secondary cutting surface for processing, so as to achieve the purpose of improving the vibration accuracy of the end wood on the side of the brake rotor. The outer diameter side of the aforementioned wheel mounting flange is designed to protrude slightly toward the wheel side.

Description

technical field [0001] The present invention relates to a bearing device for a wheel supporting a wheel of an automobile etc., in particular to a bearing device for a wheel which improves the vibration accuracy of the end surface of the flange on which the wheel is mounted and can suppress strong vibrations generated during braking. Background technique [0002] In general, contrary to the increasing popularity of disc brakes with excellent braking performance, when the disc brake rotor is clamped by the brake pads for braking, vibration will be generated when braking a vehicle traveling at low speed, This causes harsh noises at very low frequencies. This phenomenon is usually called strong vibration caused by braking. With the requirement of high performance and low noise of the vehicle, analyzing and improving this phenomenon has been paid more and more attention as a new technical subject. [0003] Although the mechanical principle of this strong vibration phenomenon has...
