Patent ID: 7785221

Claim:
A transmission unit for a motor vehicle, comprising: a drive shaft ( 11 ) for a connection to an internal combustion engine of the motor vehicle; an output shaft ( 15 ) for the driving of the motor vehicle; a change speed gearbox ( 21 ); an additional drive motor ( 23 ); and a planetary transmission ( 25 ), wherein the additional drive motor ( 23 ) is coupled to a first part ( 35 ) of the planetary transmission and the output shaft is coupled to a second part ( 37 ) of the planetary transmission, characterized in that the change speed gearbox ( 21 ) has at least one first selectable gear stage ( 3 , 5 ) via which the drive shaft ( 11 ) of the transmission unit can be operationally coupled directly to the output shaft ( 15 ) while bypassing the planetary transmission; and in that the change speed gearbox has at least one second selectable gear stage ( 1 , 2 , 4 , 6 ) via which the drive shaft ( 11 ) can be operationally coupled indirectly to the output shaft ( 15 ) via a third part ( 39 ) of the planetary transmission.
