Transmission with a motor and a speed reducer capable of being connected

In a transmission (6) having a motor (20) and a hydraulic reducer (36) comprising a rotor (34), the rotor (34) can be connected to a driven shaft(46) of the transmission (6) via a first switching element (40). The rotor (34) of the hydraulic reducer (36) can also be connected to the rotor (18) of the motor (20) via a second switching element (30). A third switching element (14) is arranged for connecting the rotor (18) of the motor (20) to the input shaft (12) of the transmission (6). The first switching element (40) and the second switching element (30) are engaged in order to form an auxiliary speed reducer composed of the hydraulic reducer (36) and the motor (20) and acting on the driven shaft (46). The second switching element (30) and the third switching element (14) are engaged in order to form a main speed reducer composed of a hydraulic reducer (36) and a motor (20) and acting on the input shaft (12). 在具有电机(20)和包括转子(34)的液力减速器(36)的传动装置(6)中，转子(34)能够经由第切换元件(40)与传动装置(6)的待制动的从动轴(46)连接。液力减速器(36)的转子(34)能够经由第
