Abstract

The invention relates to a two axis electric drive. The electric drive for a vehicle includes an electric motor and a planetary gear assembly including a sun gear drivingly connected to a rotor of the electric motor. A ring gear of the planetary gear assembly is connected to a brake that can be released to provide the system with a disconnect. A first transfer gear is connected to the planetary carrier. A second transfer gear is drivingly engaged with the first transfer gear and rotatable about a second axis offset from an axis of the electric motor. A differential is drivingly connected to the second transfer gear and provides drive torque to a pair of drive shafts along the second axis.

Description

technical field [0001] The present disclosure relates to electric drives for vehicles, and more particularly to two-axle electric drives for vehicles. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Most of the motor vehicles currently in use are driven by fuel engines, which suffer from large mechanical losses and have low energy efficiency, thereby consuming large amounts of energy and causing environmental pollution. Hybrid electric vehicles and electric vehicles have grown in popularity in recent years as battery technology has improved. However, the packaging requirements of conventional electric motor drive systems have impacted vehicle design and efficiency. Accordingly, it would be desirable to provide an electric drive with a more compact arrangement and reduced weight to provide improved efficiency. Contents of the invention [0004] This section provides ...
