1. A drive axle assembly comprising:
- an input shaft configured to receive a torque;
an interaxle differential unit disposed on the input shaft;
a drive gear disposed on the input shaft that is configured to be driven by the interaxle differential unit;
a pinion that is spaced apart from the input shaft and that engages a ring gear that is coupled to a wheel axle output shaft;
a sleeve fixedly disposed on the pinion;
a driven gear that is disposed on the sleeve;
a lock collar that is disposed on the sleeve; and
an actuator unit configured to move the lock collar between a first position in which the driven gear transmits torque to the pinion and a second position in which the driven gear does not transmit torque to the pinion.

Abstract
A drive axle assembly that may include an input shaft, an output shaft, a lock collar, and a pinion. The actuator unit may move the lock collar between a first position in which the torque is transmitted from the input shaft to the pinion and a second position in which torque is not transmitted to the pinion.

10. A drive axle assembly comprising:
-
an input shaft; an output shaft spaced apart from the input shaft; 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 output shaft, wherein the interaxle differential unit transmits torque from the input shaft to the output shaft via the output gear; a drive gear that engages the interaxle differential unit; a driven gear that engages the drive gear; a sleeve that extends through the driven gear; a pinion that extends through the sleeve and is operatively coupled to a wheel axle output shaft; and a lock collar that receives the sleeve, wherein the lock collar is positionable between a first position in which the lock collar engages the driven gear to transmit torque from the driven gear to the pinion and a second position in which the lock collar is spaced apart from the driven gear and does not transmit torque from the driven gear to the pinion. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A drive axle assembly comprising:
-
an input 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 receives the pinion and that engages the drive gear; a sleeve that engages the pinion and the driven gear; a lock collar that engages the sleeve and is configured to selectively engage the driven 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 output shaft; wherein torque is transmitted from the input shaft to the output shaft and the wheel axle output shaft when the lock collar engages the driven gear, and wherein torque is transmitted from the input shaft to the output shaft but not to the wheel axle output shaft when the lock collar does not engage the driven gear. - View Dependent Claims (19, 20)
