Abstract
A bearing assembly for a vehicle includes an inner race having an interior surface and an exterior surface, an outer race having an interior surface and an exterior surface, a first sealing member disposed between the inner race and the outer race, the first sealing member having a sealing surface adjacent to the interior surface of the outer race, and a second sealing member disposed radially inward of the first sealing member and adjacent to a shoulder surface of the outer race, wherein the first sealing member permits grease bleed-off from the bearing prior to the first sealing member setting against the second sealing member.
Claims17
A bearing rotatable about a bearing axis and defining a center plane, comprising:
- an inner race having an interior surface and an exterior surface;
- an outer race having an interior surface and an exterior surface;
- a first sealing member disposed between the inner race and the outer race, the first sealing member having a sealing surface adjacent to the interior surface of the outer race;
- and
- a second sealing member disposed radially inward of the first sealing member and adjacent to a shoulder surface of the outer race;
- wherein the first sealing member permits grease bleed-off from the bearing prior to the first sealing member setting against the second sealing member;
- and
- wherein the first sealing member comprises a first leg extending radially parallel to the interior surface of the outer race and a second leg perpendicular to and radially outward of the first leg, and the first leg includes the sealing surface and at least a portion of the second leg extends above the sealing surface towards the interior surface of the outer race.
A cartridge bearing assembly for a propshaft of an automotive vehicle, comprising:
- a ball bearing in a bearing housing;
- an inner race having an interior surface adjacent to the ball bearing and an exterior surface coupled to the propshaft;
- an outer race having an interior surface adjacent to the ball bearing and an exterior surface;
- a first sealing member disposed between the inner race and the outer race, the first sealing member having a sealing surface adjacent to the interior surface of the outer race;
- and
- a second sealing member disposed radially inward of the first sealing member and adjacent to a shoulder surface of the outer race;
- wherein the first sealing member and the interior surface of the outer race define a groove and the groove is sealed when the first sealing member seats against the second sealing member and the first sealing member comprises a first leg extending radially parallel to the interior surface of the outer race and a second leg perpendicular to and radially outward of the first leg, and the first leg includes the sealing surface and at least a portion of the second leg extends above the sealing surface towards the interior surface of the outer race.
A propshaft bearing assembly for a vehicle, comprising:
- a shaft rotatable about an axis;
- a bearing rotatable about the axis, wherein the bearing defines a center plane and comprises
- an inner race having an interior surface and an exterior surface coupled to the propshaft;
- an outer race having an interior surface and an exterior surface;
- a first sealing member disposed between the inner race and the outer race, the first sealing member having a first leg extending radially parallel to the interior surface of the outer race and a second leg perpendicular to and radially outward of the first leg, the first leg including a sealing surface adjacent to the interior surface of the outer race such that the sealing surface and the interior surface form a groove and at least a portion of the second leg extends above the sealing surface towards the interior surface of the outer race;
- a second sealing member disposed radially inward of the first sealing member;
- a third sealing member extending between the inner race and the outer race and including at least one lip seal that interfaces with the exterior surface of the inner race;
- and
- a flange disposed radially outward of the third sealing member.
