Abstract
In an infinitely variable transmission with a continuously variable transmission (CVT), a planetary gearset, a power recirculation mode clutch, and a direct mode clutch, a torque split mode reduction gear and clutch device is connected to a unit input shaft and located parallel to a power recirculation mode reduction gear and clutch device. The power recirculation mode clutch is provided for inputting a torque greater than a torque through the unit input shaft into the CVT with the power recirculation mode clutch engaged. The torque split mode clutch is provided for inputting a torque smaller than the torque through the unit input shaft into the CVT with the torque split mode clutch engaged. The power recirculation mode clutch, the direct mode clutch, and the torque split mode clutch are selectively engaged and disengaged for establishing either of a power recirculation mode, a direct mode, and a torque split mode.
