A transmission device for a motor vehicle includes a multi-speed transmission; a multidisc clutch assigned to the multi-speed transmission for changing gears of the multi-speed transmission, and an actuating device for actuating the multidisc clutch, wherein the actuating device has a wedge mechanism which is operatively connected with the multidisc clutch for actuating the multidisc clutch.

Transmission device for a motor vehicle

A drive device for a motor vehicle, having at least one first drive assembly, at least one second drive assembly, as well as a differential gearing. An input shaft of the differential gearing can be operatively connected to a drive shaft of the first drive assembly by way of a first gear train and to a drive shaft of the second drive assembly. The drive shaft of the second drive assembly is arranged at an offset relative to an intermediate shaft which is coaxial to the drive shaft of the first drive assembly, and is operatively connected by way of a second gear train to the intermediate shaft, and also by way of the intermediate shaft to the differential gearing.

Drive device for a motor vehicle

At least one electric motor is employed for propelling an electric or hybrid vehicle with a shiftable transmission. Upon reaching a shift threshold, a shift operation is performed in the transmission of the vehicle, wherein a value specifying the shift threshold is varied depending on at least one parameter. As the at least one parameter, a speed is used, at which a power provided by the at least one electric motor for propelling the vehicle has a maximum.

Method for operating an electric or hybrid vehicle with shiftable transmission and electric or hybrid vehicle

In a method for operating a hybrid drive device of a motor vehicle, a speed ratio between an electric machine of the hybrid drive device and an output shaft of the hybrid drive device is reduced by a transmission, when a temperature of the electric machine exceeds a first temperature limit value.
