Abstract

A modular transmission assembly includes a transmission housing that defines a hollow interior. The transmission housing extends along a central axis between a front end and a rear end. A rear motor module is disposed in, and is operatively connected to, the transmission housing. An inner module is disposed in, and is operatively connected to, the transmission housing. A main shaft is disposed along the central axis such that each of the rear and inner modules radially surround the main shaft. A front motor is disposed in the transmission housing and radially surrounds the main shaft. The inner module is axially disposed between the rear motor module and the front motor. An input module is connected to the front end of the transmission housing. The front motor is axially disposed between the inner module and the input module.
