A transmission has an input shaft, an output shaft coaxial to the input shaft, an intermediate shaft, a differential gear, and only one electric machine for driving a hybrid vehicle. The rotational axes of the input shaft, the intermediate shaft, the differential gear, and a rotor of the electric machine are axially parallel. The differential gear includes torque-transmitting interfaces to drive shafts connected to driving wheels of the hybrid vehicle. Torque is transmitted between the output shaft and the differential gear via the intermediate shaft. The rotor is permanently connected, via a constant gear ratio, to either the input shaft or a further shaft of the transmission. The rotational axis of the intermediate shaft is arranged spatially below a connection line between the rotational axes of the input shaft and the differential gear, and the rotational axis of the rotor is arranged spatially above the connection line.

Construction of a transmission for a hybrid vehicle, drive train and hybrid vehicle

A transmission (G) includes an input shaft (GW), an output shaft (GW), an electric machine (EM), a plurality of planetary gear sets (P-PP-P), and gear-implementing shift elements (S-SS-S). Via engagement of a first of the gear-implementing shift elements (SS), which is a force-locking shift element having a variable torque transmission capacity, the input shaft (GW) and an element (EE) of one of the planetary gear sets (PP) can be brought into a fixed rotational speed relationship with respect to each other. Another element (EEE) of one of the planetary gear sets (PPP) is permanently connected to a rotor (R) of the electric machine (EM). By engaging an auxiliary shift element (ZS,ZSa,ZSb), which is a form-locking shift element, the rotor (R) and the input shaft (GW) can be brought into a fixed rotational speed relationship with respect to each other.

Transmission for a motor vehicle, drive train and method for operating a transmission

A dog clutch () includes a piston () that is firmly connected to a sensor bolt () at one axial end of the sensor bolt (). The piston () is coaxially aligned with the sensor bolt (), and the sensor bolt () is configured as a sensor element for a position sensor () at a sensor section () of the sensor bolt () that is positioned on a free, piston-remote axial end () of the sensor bolt ().

The externally fitted control device includes an electronic control module (), a hydraulic control module () and a common control enclosure (). The hydraulic control module () has electromagnetic actuators () and control pistons () which are positioned on top of one another to result in a compact design which is safe to operate and can be manufactured economically.
