Abstract
A CVT drive train including an input drive is disclosed. A torque converter is downstream from the input drive in a power flow direction and contained within a torque converter housing, where the torque converter serves as a starting element. A disconnect clutch is contained within the torque converter housing along with a converter bridging clutch. The bridging clutch is combined with the disconnect clutch such that the impeller shell acts as a friction member for both clutches. In this way, the bridging clutch is positioned between a turbine shell and an impeller shell and the disconnect clutch is positioned between the impeller shell and housing of the torque converter. A continuously variable variator is operatively connected to and arranged downstream from the torque converter, and a rotation reversing device is downstream of the variator to enable a shift between a neutral position of the drive train and one of a forward driving position and a reverse driving position.
