Abstract
An axle assembly having a gear reduction unit and an interaxle different unit. The gear reduction unit may be operatively connected to an input shaft and may selectively provide gear reduction to a differential assembly and the interaxle differential unit. The interaxle differential unit may operatively connect the gear reduction unit to the output shaft.
Claims9
An axle assembly comprising:
- a housing assembly that receives a differential assembly;
- an input shaft that is rotatable about a first axis and is at least partially received in the housing assembly;
- a gear reduction unit that is disposed in the housing assembly and is operatively connected to the input shaft, wherein the gear reduction unit includes a planetary gear set that has a sun gear that is rotatable about the first axis, a planet carrier that rotatably supports a planet pinion, and a ring gear that is fixedly positioned with respect to the housing assembly;
- and
- a first coupling that is moveable between a first position in which the first coupling couples the input shaft to the sun gear such that the sun gear and input shaft are rotatable together about the first axis and a second position in which the first coupling couples the input shaft to the planet carrier such that the planet carrier and the input shaft are rotatable together about the first axis;
- and
- an interaxle differential unit that is received in a case that is at least partially defined by the planet carrier and that operatively connects the planetary gear set to the differential assembly and an output shaft.
