Abstract
A wheel bearing assembly is provided. The wheel bearing assembly includes an outer ring, a wheel hub rotating relative to the outer ring, the wheel hub including a hub flange, an inboard surface of the hub flange facing an outboard surface of the outer ring and spaced a gap apart from the outboard surface of the outer ring in an axial direction, a plurality of rolling elements rotatably coupling the outer ring and the wheel hub, a first spacer disposed between the inboard surface of the hub flange and the outboard surface of the outer ring, and a second spacer disposed between the first spacer and the outboard surface of the outer ring. At least a portion of the first spacer and at least a portion of the second spacer are disposed in the gap.
Claims18
A wheel bearing assembly, comprising:
- an outer ring;
- a wheel hub rotating relative to the outer ring, the wheel hub including a hub flange, an inboard surface of the hub flange facing an outboard surface of the outer ring and spaced a gap apart from the outboard surface of the outer ring in an axial direction;
- a plurality of rolling elements rotatably coupling the outer ring and the wheel hub;
- a first spacer disposed between the inboard surface of the hub flange and the outboard surface of the outer ring, the first spacer including an axially extending inner portion extending in the axial direction to cover a radial outer surface of the outer ring, and the first spacer including an axially extending outer portion extending from the axially extending inner portion in the axial direction toward the inboard surface of the hub flange;
- and
- a second spacer disposed between the first spacer and the outboard surface of the outer ring,
- wherein at least a portion of the first spacer and at least a portion of the second spacer are disposed in the gap.
A vehicle comprising:
- a wheel bearing assembly configured to be coupled to a wheel of the vehicle, the wheel bearing comprising:
- an outer ring;
- a wheel hub rotating relative to the outer ring, the wheel hub including a hub flange, an inboard surface of the hub flange facing an outboard surface of the outer ring and spaced a gap apart from the outboard surface of the outer ring in an axial direction;
- a plurality of rolling elements rotatably coupling the outer ring and the wheel hub;
- a first spacer disposed between the inboard surface of the hub flange and the outboard surface of the outer ring;
- and
- a second spacer disposed between the first spacer and the outboard surface of the outer ring, the second spacer includes a radially extending outer portion that extends in a radial direction to cover the outboard surface of the outer ring, and an axially extending inner portion that extends in the axial direction to cover a radial inner surface of the outer ring, and a radially extending inner portion;
- wherein the radially extending inner portion is axially spaced from the radially extending outer portion with the axially extending inner portion disposed axially between the radially extending inner portion and the radially extending outer portion;
- and
- wherein at least a portion of the first spacer and at least a portion of the second spacer are disposed in the gap, and
- wherein the first spacer includes an axially extending inner portion extending in the axial direction to cover a radial outer surface of the outer ring, and the first spacer includes an axially extending outer portion extending from the axially extending inner portion in the axial direction toward the inboard surface of the hub flange.
A wheel bearing assembly, comprising:
- an outer ring;
- a wheel hub rotating relative to the outer ring, the wheel hub including a hub flange, an inboard surface of the hub flange facing an outboard surface of the outer ring and spaced a gap apart from the outboard surface of the outer ring in an axial direction;
- a plurality of rolling elements rotatably coupling the outer ring and the wheel hub;
- a first spacer disposed between the inboard surface of the hub flange and the outboard surface of the outer ring;
- and
- a second spacer disposed between the first spacer and the outboard surface of the outer ring;
- wherein at least a portion of the first spacer and at least a portion of the second spacer are disposed in the gap;
- wherein the second spacer includes an axially extending inner portion that extends in the axial direction to cover a radial inner surface of the outer ring;
- wherein the axially extending inner portion of the second spacer is disposed between the outer ring and a seal;
- and
- wherein the seal is a slinger seal.
