Abstract
An electric axle assembly is disclosed. The electric axle assembly includes a common housing with an electric motor, a continuously variable transmission, and a planetary differential. The electric motor includes an output shaft and the continuously variable transmission is connected to the output shaft. The continuously variable transmission includes a drive shaft configured to be variably driven by the output shaft. The planetary differential is connected to the drive shaft, and the planetary differential includes a carrier configured to be driven by the drive shaft and dual sun gears configured to be driven by the carrier. Wheel axles are in independent driving engagement with a respective one of the dual sun gears.
Claims16
An electric axle assembly comprising:
- a housing;
- an electric motor including an output shaft;
- a continuously variable transmission connected to the output shaft, the continuously variable transmission including a drive shaft configured to be variably driven by the output shaft;
- a planetary differential connected to the drive shaft, the planetary differential including a carrier configured to be driven by the drive shaft, and dual sun gears configured to be driven by the carrier, the planetary differential includes an outer ring that is fixed on the housing and the housing includes mounting tabs;
- and
- a first wheel axle and a second wheel axle, each said wheel axle in independent driving engagement with a respective one of the dual sun gears, wherein the electric motor, the continuously variable transmission, and the planetary differential are arranged within the housing.
