ABSTRACT:
Motor vehicle transmission, comprising an input shaft (27) adapted to be drivingly connected to an output shaft of an internal combustion engine, a variator in the form of two electric machines (22, 40) having a first and a second input/output shaft (21, 41), a planetary gear train (1) for splitting power between the input shaft (27) and one of the input/output shafts (21, 41) when transmitting torque to an output gear wheel (35) of the transmission and first clutch means (13) having an engaged position establishing torque transmission between one of the input/output shafts and the output gear wheel via the the planetary gear train and a disengaged position disrupting this torque transmission. A gear train (42, 34, 31) is arranged to enable torque transmission from one of the input/output shafts to the output gear wheel, thereby by-passing the planetary gear train. Second clutch means (39) has an engaged position to establish and a disengaged position to disrupt said last mentioned torque transmission. The gear train (42, 34, 31) has a first gear wheel (42) mounted on the input/output shaft (41) meshing with a gear wheel (34) on an intermediate shaft (33). A gear wheel31is rotatably journalled on the intermediate shaft and is lockable on the shaft by second clutch means (39) to transmit torque from the input/output shaft (41) to the output gear wheel (35).
