Abstract
A method and system for an axle assembly are provided. The axle assembly, in one example, includes a cover at least partially circumferentially surrounding a shaft, a bearing coupled to the shaft and the cover, the bearing including an outer race, and a bearing adjuster including a first axial side adjacent to the outer race and configured to set a bearing preload and/or end play. The assembly further includes a lubricant seal spaced axially away from the bearing adjuster and sealing a lubricant bore and the lubricant bore traverses the cover and extends axially toward the bearing adjuster.
Claims19
An axle assembly, comprising:
- a cover at least partially circumferentially surrounding a shaft;
- a bearing coupled to the shaft and the cover, wherein the bearing includes an outer race;
- a bearing adjuster including a first axial side adjacent to the outer race, wherein the bearing adjuster sets a bearing preload or end play;
- and
- a lubricant seal spaced axially away from the bearing adjuster and sealing a lubricant bore, wherein the lubricant bore traverses the cover and extends axially toward the bearing adjuster,
- wherein the shaft is an input shaft coupled to an output shaft of an electric machine and wherein the cover is coupled to a housing of the electric machine.
An electric axle assembly, comprising:
- a cover at least partially circumferentially surrounding an output shaft of an electric machine;
- an input shaft coupled to the output shaft and including an input shaft gear forming a mesh with a gear in a gear reduction;
- a bearing coupled to the input shaft and the cover, wherein the bearing includes an outer race;
- a bearing adjuster including a first axial side in face sharing contact with the outer race, the bearing adjuster sets a bearing preload or end play;
- and
- a lubricant seal spaced axially away from the bearing adjuster and sealing a lubricant bore, wherein the lubricant bore traverses the cover and extends axially toward the bearing adjuster.
