Abstract
A thrust plate for use in a drive assembly between an end of an axle shaft and a bearing, the bearing retained within a housing of a rotatable final drive component, the thrust plate having a first end that defines an axle engaging wear surface and a second end that includes an extension configured for fitted engagement with the bearing, the thrust plate further including a central axis of rotation, where the axle engaging wear surface is disposed transverse to the central axis. A thrust plate and bearing assembly for a final drive cover plate includes the thrust plate in combination with a spherical thrust bearing, these components also being provided in a rebuild kit.
Claims22
A thrust plate for use in a drive assembly between an end of an axle shaft and a bearing, the bearing retained within a housing of a rotatable final drive component, comprising:
- a first end defining an axle engaging wear surface;
- and
- a second end including an extension configured for fitted engagement with the bearing, wherein the thrust plate includes a central axis of rotation, the axle engaging wear surface disposed transverse to the central axis.
A thrust plate for a drive assembly between an end of an axle shaft and a bearing, the bearing retained within a housing of a rotatable final drive component, comprising:
- a first end including a cylindrical plate having an axle engaging surface and an opposing bearing engaging surface, the thrust plate having a central axis, the plate disposed transverse to the axis;
- and
- a second end including an axially aligned cylindrical extension connected to the bearing engaging surface of the cylindrical plate, the extension having a cylindrical bearing engaging outer surface configured for press fit engagement with the bearing, and an extension radius originating at the central axis.
A thrust plate and bearing assembly for a final drive cover plate, comprising:
- a spherical thrust bearing including a cone, cup and a plurality of spherical tapered rollers, the cone having an axial bore defined by an inner surface, a transverse outer cone surface, and a cone raceway, the cup having a cup raceway, the spherical tapered rollers being disposed between the cup and cone raceways;
- and
- a thrust plate having a first end, a second end, and a central axis, the first end including a cylindrical plate, the cylindrical plate including a first end surface having an axle engaging portion disposed transverse to the central axis, the cylindrical plate having a transverse bearing engaging surface opposing the first end surface, the second end including an axially aligned extension connected to the transverse bearing engaging surface, the extension having a bearing engaging outer cylindrical surface;
- wherein, the thrust plate extension is disposed within the axial bore with the transverse bearing engaging surface disposed adjacent the transverse outer cone surface.
A rebuild kit for a final drive cover plate, comprising:
- a spherical thrust bearing including a central axis, a cone, cup and a plurality of spherical tapered rollers, the cone having an axial bore defined by an inner surface, a transverse outer cone surface, and a cone raceway, the cup having a cup raceway, the spherical tapered rollers being disposed between the cup and cone raceways;
- and
- a thrust plate having a first end and a second end, the first end including a cylindrical plate, the cylindrical plate including a first end surface having an axle engaging portion disposed transverse to the central axis, the cylindrical plate having a transverse bearing engaging surface opposing the first end surface, the second end including an axially aligned extension connected to the transverse bearing engaging surface, the extension having a bearing engaging outer cylindrical surface, wherein the bearing engaging outer cylindrical surface has a radial dimension for a press fit engagement with the inner surface of the axial bore.
The rebuild kit of claim 20, further comprising a plurality of compression springs.
