Abstract

An outer member and an inner member constituting a wheel bearing device are assembled and the brake rotor is fixed to the hub ring of the inner member. In this state, the pad slide surfaces of the brake rotor are lathed with the reference provided by a wheel pilot end surface. Alternatively, the wheel pilot end surface of the hub ring by chucking the knuckle pilot of the outer member with the wheel bearing device put in its assembled state, and the pad slide surfaces of the brake rotor are lathed with the reference provided by the wheel pilot end surface.

First claim

The invention claimed is:

1. A processing method for cutting pad slide surfaces of a brake rotor of a brake rotor-equipped wheel bearing device which comprises: an outer member having a car body attaching flange at an outer periphery of the outer member and two raceways at an inner periphery of the outer member; an inner member having a hub ring with a wheel attaching flange at an outer periphery of the hub ring, an inner ring disposed at a small diameter section of the hub ring, and two raceways; two rows of rolling elements interposed between the raceways of the outer and inner members for relatively rotatably supporting the outer and inner members, and a brake rotor fixed to the wheel attaching flange of the hub ring,
the processing method comprising:
grinding, with the hub ring present singly, a hub ring outer peripheral surface with a wheel pilot end surface of the hub ring providing a reference;
assembling the outer and inner members and the rolling elements together;
fixing the brake rotor to the hub ring of the inner member; and
lathing the pad slide surfaces of the brake rotor with the wheel pilot end surface of the hub ring providing the reference.

2. The processing method as set forth in claim 1 , further comprising chucking a wheel pilot outer diameter of the hub ring during the lathing of the pad slide surfaces of the brake rotor.

3. The processing method as set forth in claim 1 , further comprising chucking a wheel pilot inner diameter of the hub ring during the lathing of the pad slide surfaces of the brake rotor.

4. The processing method set forth in claim 1 , further comprising of chucking a serration hole inner diameter of the hub ring during the lathing of the pad slide surfaces of the brake rotor.

5. The processing method as set forth in claim 1 , further comprising chucking a hat section outer diameter of the brake rotor during the lathing of the pad slide surfaces of the brake rotor.
