Abstract:
1. An automatic transmission, comprising: an input adapted to couple to a torque-generating mechanism; an output coupled to the input; a first rotating torque-transferring mechanism disposed along a first torque path, the first rotating torque-transferring mechanism being coupled to the input; a second rotating torque-transferring mechanism disposed along a second torque path, the second rotating torque-transferring mechanism being coupled to the input independent of the first torque-transferring mechanism; a first stationary torque-transferring mechanism, a second stationary torque-transferring mechanism, a third stationary torque-transferring mechanism, and a fourth stationary torque-transferring mechanism, each of the stationary torque-transferring mechanisms being disposed between the input and the output; and a first planetary gearset, a second planetary gearset, a third planetary gearset, and a fourth planetary gearset, where each planetary gearset includes a sun gear, a ring gear, and a carrier assembly; wherein, the ring gear of the third planetary gearset is coupled to the carrier assembly of the second planetary gearset and the carrier assembly of the fourth planetary gearset.
