Abstract
A pulser ring and a pickup sensor are sealingly housed by a seal so as to prevent the penetration of foreign matters. The pulser ring is fixedly mounted on one end face side of an inner ring that is mounted on a drive shaft side to thereby rotate together therewith. The seal has a resilient material mounted at a distal end of a metal ring, and is fixedly mounted on one end face side of an outer ring fixed to a vehicle body side which one end face side corresponds to the one end face side of the inner ring. The seal encompasses the pulser ring inside thereof. The resilient material of the seal is brought into close and slidable contact with an outer circumferential surface of a drive shaft. The pickup sensor is supported by the metal ring.
Claims19
A wheel bearing device comprising:
- an outer ring fixed to a vehicle body side;
- an inner ring rotatably supported by said outer ring through rolling members and mounted on a drive shaft side so as to rotate together therewith;
- a pulser ring fixedly mounted on one end face side of said inner ring;
- and
- a seal including a metal ring and an annular resilient member, a proximal end of said metal ring being fixedly mounted on one end face side of said outer ring corresponding to said one end face side of said inner ring, said annular resilient member being mounted on a distal end of said metal ring,
- wherein said pulser ring is encompassed by said seal,
- wherein said resilient member is in tight and slidable contact with an outer circumferential surface of a drive shaft,
- wherein a pickup sensor is supported by said metal ring to be opposed to said pulser ring, and
- wherein said metal ring comprises a bent portion formed at a distal end of a tapered portion.
