Abstract

An electrically driven axle for a motor vehicle comprising: an axle housing; an electric motor having an output shaft driven directly by a bevel pinion coupled thereto; a fixed ratio planetary gear arrangement; a differential unit comprising a differential gear device housed within the differential case; and a first clutch selectively operable to connect a portion of the planetary gear set to a stationary member of the drive axle such that the drive axle operates in a first gear ratio.

Description

[0001] Related Patent Applications [0002] This application claims priority to and the benefit of Provisional US Patent Application Serial No. 62 / 314,023, filed March 28, 2016. The contents of the aforementioned patent applications are expressly incorporated by reference into the detailed description of the present application. technical field [0003] The present invention relates to an electrically driven axle (also known as "axle" or "axle") for a motor vehicle, and more particularly to an electrically driven axle having a single electric motor that provides two-speed and three-speed Quick configuration. Background technique [0004] To reduce carbon emissions and air pollution, there is growing interest in hybrid and electric vehicles. Current technology for electrified electric motors used in motor vehicles has limited spread in terms of torque and speed. The use of the electric motor drive train can be optimized to efficiently transmit high torque at low speeds and...
