Motor vehicle transmission device with torque vectoring functionality and with multiple connection to an electrical machine

摘要

Transmission device (1) for a motor vehicle (2), which has an input shaft (6) that can be operatively connected to a drive device of the motor vehicle (2) as well as a first output shaft (7) and a second output shaft (8) and via a spur gear differential (15 ) has which the input shaft (6) and an intermediate shaft (28) which can be coupled to an electrical machine (29) arranged coaxially with the input shaft (6) are coupled or can be coupled to the first output shaft (7) and the second output shaft (8) , the electrical machine (29) being coupled to the input shaft (6) in a first switching position of a switching device (30) and to the intermediate shaft (28) in a second switching position of the switching device (30), characterized in that the spur gear differential (15 ) a first coupling planetary gear (24) rotatably mounted on a planetary gear carrier (18) and one coaxial to the first coupling planetary gear (24) mounted second coupling planetary gear (24 '), one of the coupling planetary gears (24, 24') transmitting torque by means of a further switching device (42) with a stationary element (43) or with the intermediate shaft (28) or the respective other of the coupling planetary gears (24, 24 ') can be coupled.
