Abstract

See full text

An electric vehicle drive unit includes an electric motor generating a torque. An input differential splits the torque into a first torque created by a first side gear and a second torque created by a second side gear. A first pinion gear shaft assembly receives the first torque and has a first pinion gear. A second pinion gear shaft assembly receives the second torque and has a second pinion gear. A first stage transfer gear assembly has a first, a second, a third, and a fourth transfer gear. A first stage speed reduction meshes the first pinion gear with the first transfer gear and the third transfer gear, and meshes the second pinion gear, the second transfer gear and the fourth transfer gear. A second stage gear assembly engages the first stage transfer gear assembly and includes a first final drive gear and a second final drive gear.
