摘要： A multi-speed transmission including a plurality of planetary gearsets and a plurality of selective couplers to achieve at least nine forward speed ratios is disclosed. The plurality of planetary gearsets may include a first planetary gearset, a second planetary gearset, a third planetary gearset, and a fourth planetary gearset. The plurality of selective couplers may include a number of clutches and a number of brakes. The multi-speed transmission may have four planetary gearsets and six selective couplers. The six selective couplers may include three clutches and three brakes.

摘要： 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.
