Abstract
An axle assembly having a gear reduction unit and an interaxle differential 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.
Claims20
An axle assembly comprising:
- a housing assembly that receives a differential assembly;
- an input shaft that is at least partially received in the housing assembly and is rotatable about a first axis;
- a gear reduction unit that is operatively connected to the input shaft, wherein the gear reduction unit includes a planetary gear set that has a sun gear and a planetary ring gear that are rotatable about the first axis and a planet carrier that rotatably supports a planet pinion that is in meshing engagement with the sun gear and the planetary ring gear, wherein the planetary ring gear is selectively rotatable about the first axis;
- a first coupling that is moveable between a first position in which the planetary ring gear is coupled to the housing assembly such that the planetary ring gear does not rotate about the first axis and a second position in which the planetary ring gear is not coupled to the housing assembly and is rotatable about the first axis;
- and
- an interaxle differential unit that is at least partially received in the planet carrier and that operatively connects the planetary gear set to the differential assembly and an output shaft.
