Traction unit drive for driving auxiliary unit e.g. climate compressor, of motor car i.e. hybrid electric car, has drivable traction unit for driving auxiliary units and electric machine that is arranged for driving drivable traction unit
The drive (1) has a combustion engine, drivable traction unit (2) i.e. driving belt, of the combustion engine, and multiple auxiliary units. The auxiliary units are driven by the drivable traction unit. An electric machine is arranged for driving the drivable traction unit. The internal combustion engine and the electric machine are provided with a common liquid cooling circuit to cool the internal combustion engine and the electric machine. The electric machine is provided with driving power to drive the auxiliary unit without the assistance of the internal combustion engine.
