Abstract
A wheel bearing (42) located between the wheel hub 14 and axle spindle (10) is supplied with lubricant located in an annular cavity between the hub and spindle. A lubricant seal (52) is fitted with slight interference between the hub and seal and defines a sealing lip (72), which is urged by a garter spring (70) into contact with an inner sleeve (76) of the seal. A slinger (58) is supported by tabs (88) on a surface of the bearing and provides a radial planar ring surface (86) located between the bearing race and seal. On assembly, the slinger provides a stop surface that limits axial movement of the inner sleeve of the seal toward the bearing.
Claims8
An assembly for an automotive vehicle axle, comprising:
- a first component;
- a second component adapted for rotation relative to the first component;
- a bearing located between the first component and second component, providing support for relative rotation therebetween;
- means for sealing a space between the first and second components against passage of fluid, having a first element contacting the first component, and second element contacting the second component, the first and second elements mutually axially displaceable and rotatable;
- and
- a slinger fixed against axial movement, having a surface located adjacent the seal for limiting movement of one of the first element and second element toward the bearing.
An assembly for an automotive vehicle axle, comprising:
- a wheel hub;
- an axle spindle adapted for rotation relative to the wheel hub;
- a bearing located between the wheel hub and axle spindle, providing support for relative rotation therebetween;
- means for sealing a space between the wheel hub and axle spindle against passage of fluid, having a radially outer sleeve frictionally contacting the wheel hub, a radially inner sleeve frictionally contacting the axle spindle, the inner and outer sleeves being mutually axially displaceable and rotatable;
- and
- a slinger fixed against axial movement, having a surface located adjacent the seal for limiting movement of one of the group consisting of the inner sleeve and the outer sleeve toward the bearing.
