Abstract
An axle assembly having a drive pinion assembly. The drive pinion assembly may have a drive pinion body, a pinion gear, and a side gear. The pinion gear may be fixedly disposed on a first end portion of the drive pinion body. The side gear may be fixedly disposed on a second end portion of the drive pinion body.
Claims20
An axle assembly comprising:
- a drive pinion assembly that includes:
- a drive pinion body that defines a drive pinion passage that extends around an axis, the drive pinion body having a first end portion and a second end portion disposed opposite the first end portion;
- a pinion gear that is fixedly disposed on the first end portion, wherein the pinion gear has a pinion gear hole that receives the drive pinion body;
- and
- a side gear that is fixedly disposed on the second end portion, wherein the side gear has a side gear hole that partially receives a spider of an interaxle differential unit that operatively connects an input shaft to an output shaft that extends through the drive pinion passage.
2 more elements
An axle assembly comprising;
- a drive pinion assembly that includes:
- a drive pinion body that defines a drive pinion passage that extends around an axis, the drive pinion body having a first end portion a second end portion disposed opposite the first end portion, and a flange that extends away from the axis, wherein the flange has a first flange surface that engages a roller bearing assembly that rotatably supports the drive pinion assembly and a second flange surface that is disposed opposite the first flange surface;
- a pinion gear that is fixedly disposed on the first end portion, wherein the pinion gear has a pinion gear hole that receives the drive pinion body;
- and
- a side gear that is fixedly disposed on the second end portion, wherein the side gear engages the second flange surface and has a side gear end surface that engages the second flange surface and a rim that extends from the side gear end surface toward the roller bearing assembly and at least partially around the flange.

An axle assembly comprising:
- a drive pinion assembly that includes:
- a drive pinion body that defines a drive pinion passage that extends around an axis, the drive pinion body having a first end portion, a second end portion disposed opposite the first end portion, and a flange that extends away from the axis;
- a pinion gear that is fixedly disposed on the first end portion, wherein the pinion gear has a pinion gear hole that receives the drive pinion body;
- and
- a side gear that is fixedly disposed on the second end portion and has a side gear hole that receives the drive pinion body, wherein the flange is received in the side gear hole and inhibits axial movement of the side gear away from the pinion gear.
