Abstract: Compact electric drive units and vehicles with such drive units are provided. An exemplary electric drive unit includes an electric motor configured to provide an electric motor torque; an input differential configured to split the electric motor torque into a first path and a second path; a final drive gear on each path; a pinion gear on each path; and a rear transfer shaft assembly and a front transfer shaft assembly on each path. Further, each pinion gear is configured to transfer torque to a respective rear transfer shaft assembly and a respective front transfer shaft assembly, and the respective rear transfer and front transfer shaft assemblies are configured to transfer torque to the respective final drive gear.

Abstract: 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.
