Abstract
An axle assembly for a vehicle including a differential assembly, a first axle tube extending outwardly from the differential assembly and including an axle bore, a first axle shaft rotatably received in the axle bore of first axle tube and including a first annular groove, an annular ring holder disposed within the axle bore of the first axle tube, a radial bearing assembly including an outer race and a plurality of roller elements being axially fixed within the axle bore of the first axle tube, a first snap ring received in the annular groove of the first axle shaft, and a thrust ring, the thrust ring being axially disposed between the radial bearing assembly and the first snap ring so that the thrust ring bears against the plurality of roller elements.
Claims21
An axle assembly of a vehicle, comprising:
- a differential assembly;
- a first axle tube extending outwardly from a first side of the differential assembly, the first axle tube including a proximal end adjacent the differential assembly, an opposite distal end, an axle bore extending therebetween, and an annular groove in the axle bore of the axle tube;
- a first axle shaft rotatably received in the first axle tube, the first axle shaft including a proximal end disposed in the differential assembly, an opposite distal end extending outwardly from the distal end of the first axle shaft, and an annular groove extending radially inwardly from its outer surface;
- an annular ring holder axially fixed within the axle bore of the first axle tube;
- a radial bearing assembly including an outer race that is axially fixed with regard to the axle tube and a plurality of roller elements rotatably received therein, the radial bearing assembly being disposed within the axle bore of the first axle tube;
- a first snap ring received in the annular groove of the first axle shaft;
- a second snap ring received in the annular groove of the axle tube, wherein the annular groove is between the distal end of the axle tube and the radial bearing assembly and the second snap ring is adjacent the outer race of the radial bearing assembly;
- and
- a thrust ring, the thrust ring being disposed within the axle bore of the first axle tube between the radial bearing assembly and the first snap ring so that the thrust ring abuts the radial bearing assembly.
An axle assembly of a vehicle, comprising:
- a differential assembly;
- a first axle tube extending outwardly from a first side of the differential assembly, the first axle tube including a proximal end adjacent the differential assembly, an opposite distal end, an axle bore extending therebetween;
- a first axle shaft rotatably received in the first axle tube, the first axle shaft including a proximal end disposed in the differential assembly, an opposite distal end extending outwardly from the distal end of the first axle shaft, and an annular groove extending radially inwardly from its outer surface;
- a radial bearing assembly including an outer race and a plurality of roller elements rotatably received therein, the radial bearing assembly being disposed within the axle bore of the first axle tube;
- a first snap ring received in the annular groove of the first axle shaft;
- and
- a thrust ring that is being axially disposed between the radial bearing assembly and the first snap ring in the axle bore of the first axle tube so that the thrust ring bears against the radial bearing assembly,
- wherein the first snap ring transmits axially directed force from the first axle shaft to the radial bearing assembly.
An axle assembly of a vehicle, comprising:
- a differential assembly;
- a first axle tube extending outwardly from a first side of the differential assembly, the first axle tube including a proximal end adjacent the differential assembly, an opposite distal end, an axle bore extending therebetween, and an annular groove in the axle bore of the axle tube;
- a first axle shaft rotatably received in the first axle tube, the first axle shaft including a proximal end disposed in the differential assembly, an opposite distal end extending outwardly from the distal end of the first axle shaft, and an annular groove extending radially inwardly from its outer surface;
- a radial bearing assembly including an outer race that axially fixed with regard to the axile tube and a plurality of roller elements rotatably received therein, the radial bearing assembly being disposed within the axle bore of the first axle tube;
- a first snap ring received in the annular groove of the first axle shaft;
- and
- a second snap ring received in the annular groove of the axle tube, wherein the annular groove is between the distal end of the axle tube and the radial bearing assembly,
- wherein the first snap ring transmits axially directed force from the first axle shaft to the radial bearing assembly.
