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.
Claims5
A processing method for cutting the pad slide surface of the brake rotor of a brake rotor-equipped wheel bearing device which comprises an outer member having a car body attaching flange in the outer periphery and two rows of raceways in the inner periphery, an inner member consisting of a hub ring having a wheel attaching flange in the outer periphery and an inner ring disposed in the small diameter section of the hub ring, two rows of rolling elements interposed between the raceways of the outer and inner members for relatively rotatably supporting the two members, and a brake rotor fixed to the wheel attaching flange of the hub ring,
- said processing method comprising the steps of
- lathing, with the hub ring present singly, the wheel pilot end surface of the hub ring with the reference provided by the raceway of the hub ring,
- 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 reference provided by the pilot wheel end surface of the hub ring.
