Drive device for driving motor car, has torque converter switched on in power flow to sub transmission, and electrical machine provided before or after converter in force flow for obtaining temporary hybrid drive or electrical drive

摘要

The device has a driving internal combustion engine, and a downstream dual-clutch transmission (10) including two sub transmissions (I, II), which are alternatingly activated by two separation clutches (K1, K2). A hydrodynamic torque converter (20) is switched on in a power flow to one of the sub transmissions. An electrical machine (24) is provided before or after the torque converter in a force flow for obtaining a temporary hybrid drive or an electrical drive. A rotor (28) of the electrical machine is directly arranged on a hollow input shaft.
