摘要

The transmission has an electrical machine (8) provided as a starter and a generator and/or for partial electrical drive operation of a vehicle. The machine is connected with an internal combustion engine by a coupler (K4) and with a shaft of a planet wheel set (5) by a coupler (K5). The two couplers (K4, K5) connects the engine with an internal gear (17) of the planet wheel set and/or the electrical machine is connected with the internal gear of the planet wheel set by the coupler (K5).
