Abstract
An axle assembly for a motor vehicle includes a pair of axle half-shafts that are adapted to transfer rotational motion to a pair of spaced apart wheels. A differential is positioned between the axle half-shafts and a dual planetary gear set is positioned between and interconnects each axle half-shaft to the differential. Each dual planetary gear set includes a first planetary gear set and a second planetary gear set mounted adjacent one another, back to back, and having a shared ring gear.
Claims15
An axle assembly for a motor vehicle comprising:
- a pair of rotatably supported axle half-shafts adapted to transfer rotational motion to a pair of wheels spaced from one another;
- a differential positioned between the axle half-shafts and including a differential input adapted to receive rotational motion from a transmission of the motor vehicle;
- a dual planetary gear set positioned between and interconnecting each axle half-shaft and the differential, each of the dual planetary gear sets including a first planetary gear set and a second planetary gear set mounted adjacent one another and having a shared ring gear that is stationarily mounted within the axle assembly.
