1. A drive axle assembly comprising:
- an input shaft configured to receive a torque;
an output shaft that is spaced apart from the input shaft;
an interaxle differential unit disposed on the input shaft;
an intermediate shaft that is disposed between the input and output shafts and configured to be driven by the interaxle differential unit; and
an actuator unit configured to move the intermediate shaft between a first position in which the intermediate shaft engages and transmits torque to the output shaft and a second position in which the intermediate shaft does not engage or transmit torque to the output shaft.

Abstract
A drive axle assembly that may include an input shaft, an intermediate shaft, an output shaft, and an actuator unit. The actuator unit may move the intermediate shaft between a first position in which the intermediate shaft transmits torque to the output shaft and a second position in which the intermediate shaft does not transmit torque to the output shaft.

8. A drive axle assembly comprising:
-
an input shaft; an output shaft spaced apart from the input shaft; an intermediate shaft disposed between the input and output shafts, wherein the intermediate shaft is positionable in a first position in which the intermediate shaft engages the output shaft and a second position in which the intermediate shaft is spaced apart from the output shaft; and an interaxle differential unit disposed on the input shaft, wherein the interaxle differential unit includes an output gear that includes a center bore that receives the input shaft and the intermediate shaft; wherein the interaxle differential unit transmits torque from the input shaft to the intermediate shaft via the output gear. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A drive axle assembly comprising:
-
an input shaft, an intermediate shaft, and an output shaft disposed along a first axis of rotation; a pinion disposed along a second axis of rotation, the pinion being configured to provide torque to a wheel axle output shaft; a drive gear disposed on the input shaft; a driven gear that is disposed on the pinion and that engages the drive gear; and an interaxle differential unit disposed on and configured to be driven by the input shaft, wherein the interaxle differential unit is configured to rotate the drive gear and the intermediate shaft; wherein torque is transmitted from the input shaft to the output shaft and the wheel axle output shaft when the intermediate shaft engages the output shaft, and wherein torque is transmitted from the input shaft to the wheel axle output shaft but not to the output shaft when the intermediate shaft does not engage the output shaft. - View Dependent Claims (16, 17, 18, 19, 20)
