Abstract

The invention relates to a hybrid drive, comprising an internal combustion engine, an electric machine and a torque superposition device, by means of which a torque supplied by the internal combustion engine can be superposed on a torque supplied by the electric machine, wherein the torque superposition device has a first and a second torque input and a torque output. The electric machine is coupled to the first torque input via a first transmission device, and the internal combustion engine is coupled to the second torque input via a second transmission device.
