Abstract
A wheel bearing device comprises a rotor having a double row of raceway surfaces and having a wheel fixed thereto, an outer ring having a double row of raceway surfaces and a flange to be fixed to a knuckle disposed on the car body side, and a double row of rolling bodies interposed between the respective raceway surfaces of the rotor and outer ring. A pulser ring is disposed between the double row of raceway surfaces of the rotor, and a sensor opposed to the pulser ring is held by a holding member held between the flange of the outer ring and the knuckle, whereby the sensor can be disposed in the bearing inner space.

A wheel bearing device including a rotor having a double row of raceway surfaces and adapted to have a wheel fixed thereto, a stator having a double row of raceway surfaces and a flange for fixing to an attaching member on the car body side, and a double row of rolling bodies interposed between the respective raceway surfaces of the rotor and stator, the wheel being rotatably supported on the car body, characterized in that installed between said double row of raceway surfaces of the rotor is a sensed part, and a sensor opposed to said sensed part is held by a holding member held between said flange of the stator and said attaching member.
A wheel bearing device comprising a fixed member attached to a car body, an outer member fitted in said fixed member and formed with a double row of raceway surfaces on its inner periphery, an inner member formed with a double row of raceway surfaces on its outer peripheral surface opposed to the raceway surfaces of said outer member and having a wheel attaching flange, a double row of rolling bodies interposed between the raceway surfaces of said outer and inner members, the wheel being rotatably supported by the car body, said wheel bearing device being characterized in that an rpm detecting sensor is fitted in a hole formed to extend radially through said fixed and outer members and is opposed to a sensed part disposed between the raceway surfaces of said inner member.
A wheel bearing device including rotary raceway surfaces formed in a double row in a rotor rotating together with a wheel, fixed raceway surfaces formed in a double row on the car body side, a double row of rolling bodies interposed between the rotary raceway surfaces and the fixed raceway surfaces, the wheel being supported for rotation with respect to an attaching member extending from the car body, said wheel bearing device being characterized in that
- the inner peripheral surface of said attaching member is provided with an opposing portion disposed between the double row of rotary raceway surfaces and opposed to the outer peripheral surface of the rotor, and a pair of outer rings having said fixed raceway surfaces are fitted in the inner peripheral surface of the attaching member and on the axial opposite sides of the opposing portion.
