Abstract: An electrically-variable transmission for a vehicle is disclosed. The transmission includes an input member and an output member each rotatable about a first axis. The transmission includes a casing defining a cavity between a first end wall and a second end wall. The transmission includes a first motor/generator and a second motor/generator disposed in the cavity with a second planetary gear set disposed between the first and second motor/generators along the first axis. The transmission includes a first torque-transmitting mechanism disposed between the first and second motor/generators along the first axis. The transmission includes a second torque-transmitting mechanism disposed between the first end wall and the first motor/generator along the first axis. The first motor/generator is disposed between the first and second torque-transmitting mechanisms along the first axis. The transmission includes a damper mechanism disposed between the second end wall and a first planetary gear set along the first axis.
