Abstract: Systems, devices, and methods are provided for the transmission of power in motor vehicles. Power can be transmitted in a smoother and more efficient manner, with smaller and even less mechanical components, by splitting torque into two or more torque paths. A power transmission apparatus comprises a power input shaft, a planetary gear set coupled to the power input shaft, and a variator, such as a continuously variable transmission (CVT), coupled to the gear set. The various components of the planetary gear set and the variator are arranged such that torque is split between two or more torque paths and then recombined before power is output to a gear box and a differential of the motor vehicle.

Abstract: An automatic transmission includes a continuously variable transmission mechanism, a planetary gear mechanism, a clutch causing an input shaft and a first rotation element to be engaged, a coupling member which transmits rotation of the input shaft to the first rotation element, and a brake which locks rotation of a third rotation element. The input shaft is coupled to an input unit. An output shaft is coupled to a second rotation element An output unit is coupled to a fourth rotation element. The constant speed ratio of the coupling member is so set that a rotation direction of the output shaft relative to the fourth rotation element changes from a forward direction to a reverse direction according to a change in a speed ratio of the continuously variable transmission mechanism when the clutch is engaged and the brake is released.
