Abstract
An axle assembly that may include a housing assembly, a case, an interaxle differential unit, drive pinion, and an output shaft. The axle assembly may further include a clutch collar that is moveable between a first position and a second position to engage and disengage a rotatably drivable member and the drive pinion.
Claims20
An axle assembly comprising:
- a housing assembly;
- a case that is disposed in the housing assembly and is rotatable about a first axis;
- an interaxle differential unit that is disposed in the case and that has a rotatably drivable member;
- a drive pinion that is selectively connected to the interaxle differential unit and configured to provide torque to a differential assembly that includes a ring gear, wherein the drive pinion has a gear portion that has teeth that mate with teeth of the ring gear;
- an output shaft that is received in the drive pinion and that is operatively connected to the interaxle differential unit;
- and
- a clutch collar that is moveable along the first axis between a first position in which the rotatably drivable member is rotatable with respect to the case and the rotatably drivable member and drive pinion are configured to rotate together about the first axis, and a second position in which the rotatably drivable member is not rotatable with respect to the case and the rotatably drivable member and the case are rotatable with respect to the drive pinion.

An axle assembly comprising:
- a housing assembly;
- a case that is disposed in the housing assembly and is rotatable about a first axis, wherein the case includes a first case portion adapted to be rotated about the first axis by an input shaft, and a second case portion disposed on the first case portion, the second case portion defining an annular spline disposed about an aperture of the second case portion;
- an interaxle differential unit that is disposed in the case and that has a first side gear;
- a drive pinion that is selectively connected to the interaxle differential unit and configured to provide torque to a differential assembly;
- an output shaft that is received in the drive pinion and that is operatively connected to the interaxle differential unit;
- and
- a clutch collar that is moveable along the first axis between a first position in which the first side gear is rotatable with respect to the case and the first side gear and drive pinion are configured to rotate together about the first axis, and a second position in which the first side gear is not rotatable with respect to the case and the first side gear and the case are rotatable with respect to the drive pinion.

An axle assembly comprising:
- a housing assembly;
- a case that is disposed in the housing assembly and is rotatable about a first axis, wherein the case includes a first case portion adapted to be rotated about the first axis by an input shaft and a planet carrier disposed on the first case portion, the planet carrier defining an annular spline disposed about an aperture of the planet carrier;
- an interaxle differential unit that is disposed in the case and that has a sun gear;
- a drive pinion that is selectively connected to the interaxle differential unit and configured to provide torque to a differential assembly;
- an output shaft that is received in the drive pinion and that is operatively connected to the interaxle differential unit;
- and
- a clutch collar that is moveable along the first axis between a first position in which the sun gear is rotatable with respect to the case and the sun gear and drive pinion are configured to rotate together about the first axis, and a second position in which the sun gear is not rotatable with respect to the case and the sun gear and the case are rotatable with respect to the drive pinion.
