Abstract: A parallel axis gearbox is provided for a vehicle. The parallel axis gearbox includes an input shaft having a first axis of rotation and an intermediate shaft having a second axis of rotation parallel to the first axis of rotation. The intermediate shaft includes an intermediate driving gear, an intermediate driven gear, and a longitudinal bore passing through the intermediate shaft. The intermediate driven gear is meshingly engaged with a first driving gear on the input shaft. The input shaft and the intermediate shaft are contained within and supported by a cover fixedly coupled to a housing. A bolt fixedly couples the cover to the housing and passes through the longitudinal bore of the intermediate shaft.

Abstract: Bearings (72, 74) are arranged for a drive unit (10) having an electric motor for providing drive to an electric axle and a wheel assembly of a vehicle. The drive unit includes a pair of bearings and a reduction gear assembly (12) with a first drive gear mounted to and coaxial with the main shaft of the motor, and a first driven gear rotatably coupled to the first drive gear and mounted to and coaxial with an intermediate shaft to form an intermediate shaft assembly. The reduction gear assembly includes a second drive gear mounted to and coaxial with the intermediate shaft, and a second driven gear rotatably coupled with the second drive gear. A first bearing of said pair of bearings is mounted to a bulkhead and to said intermediate shaft assembly between the first driven gear and second drive gear to reduce the distance between the first and second bearings.

Abstract: A coaxial electrified drive axle is provided for a vehicle. The coaxial electrified drive axle has an electric motor connected to a gear box housing containing a stepped planetary gear set operatively coupling a drive shaft of the electric motor to a linkshaft and an output shaft through a differential assembly. The differential assembly is contained within a carrier which also supports the planet gears through planet pins. The carrier is supported by a single carrier support bearing. The drive shaft, the linkshaft, and the output shaft are coaxial and share a common axis of rotation.
