1. An electrically-variable transmission for a vehicle, the transmission comprising:
an input member and an output member each rotatable about a first axis; a casing including a side wall cooperating with a first end wall and a second end wall to define a cavity enclosed by the side wall and the first and second end walls, with the first and second end walls spaced from each other along the first axis and the side wall spaced radially away from the first axis; a first planetary gear set and a second planetary gear set each disposed in the cavity, and each having a sun gear, a carrier rotatably supporting a plurality of pinion gears, and a ring gear, with the pinion gears of the first planetary gear set meshing with the sun gear and the ring gear of the first planetary gear set, and the pinion gears of the second planetary gear set meshing with the sun gear and the ring gear of the second planetary gear set; a first motor/generator and a second motor/generator disposed in the cavity and spaced from each other along the first axis such that the second planetary gear set is disposed between the first and second motor/generators along the first axis, with the first motor/generator connected for rotation with the sun gear of the first planetary gear set and the second motor/generator connected for rotation with the sun gear of the second planetary gear set; a first support disposed inside the cavity of the casing and attached to the casing from inside the cavity, with the first motor/generator secured to the first support such that the first support supports the first motor/generator; a first torque-transmitting mechanism disposed in the cavity and selectively actuated to ground the ring gear of the second planetary gear set to the casing, with the first torque-transmitting mechanism disposed between the first and second motor/generators along the first axis; a second torque-transmitting mechanism disposed in the cavity and selectively actuated to connect the sun gear of the first planetary gear set with the ring gear of the second planetary gear set, with the second torque-transmitting mechanism disposed between the first end wall and the first motor/generator along the first axis, and with the first motor/generator disposed between the first and second torque-transmitting mechanisms along the first axis; and a damper mechanism coupled to the input member and the first planetary gear set in the cavity, with the damper mechanism disposed between the second end wall and the first planetary gear set along the first axis.
