Abstract

A drive train for a hybrid motor vehicle having a gearbox input shaft operatively connected to a first electric machine and an internal combustion engine via a first partial drive train to transmit torque and which is operatively connected to a second electric machine via a second partial drive train to transmit torque. The second electric machine is permanently connected to the gearbox input shaft for torque transmission and the first electric machine and the internal combustion engine can be connected to the gearbox input shaft in a coupleable manner to transmit torque. The first electric machine and the second electric machine are arranged coaxially to one another, and driven shaft of the first electric machine is arranged radially inside a driven shaft of the second electric machine. The driven shaft of the first electric machine is mounted on the driven shaft of the second electric machine via a bearing.
