Abstract
A method of controlling a drive axle system. The drive axle system may include first and second drive axle assemblies. A drive axle assembly may be disconnected by operating a wheel end disconnect to discontinue transmission of torque between a wheel assembly and a differential and by discontinuing the transmission of torque to the differential.
Claims20
A method of controlling a drive axle system, the method comprising:
- providing an axle assembly having an interaxle differential unit, a shift collar, a differential, a wheel end assembly having a wheel end disconnect, and a wheel assembly;
- reducing an input torque to the interaxle differential unit that is operatively connectable to the differential with the shift collar;
- operating the wheel end disconnect to discontinue transmission of torque from the differential to the wheel assembly;
- and
- subsequently shifting the shift collar to discontinue transmission of torque to the differential.

A method of controlling a drive axle system, the method comprising:
- providing an axle assembly having an interaxle differential unit that is rotatable about a first axis, a shift collar, a differential, first and second axle shafts, a first wheel end assembly having a first wheel end disconnect and a first hub assembly, and a second wheel end assembly having a second wheel end disconnect and a second hub assembly;
- locking the differential such that the first and second axle shafts rotate together about a second axis;
- operating the first and second wheel end disconnects to enable torque transmission between the first and second hub assemblies and the differential;
- reducing an input torque to the interaxle differential unit that is operatively connectable to the differential with the shift collar;
- and
- shifting the shift collar to enable transmission of torque to the differential from the interaxle differential unit.
