摘要:
An electric machine (14, 16) for a drive train (12) of a motor vehicle (10) has a coil arrangement and a rotor mounted rotatably relative to the coil arrangement. A fluid line is connected thermally to at least one component of the electric machine (14,16) to supply a cooling fluid (36) to the electric machine (14, 16) and to cool the at least one component. A fan (30, 32) is designed to supply cooling air (42) to the electric machine for cooling the electric machine (14, 16), and a control unit (34) controls the fan (30, 32). The control unit (34) controls the fan arrangement (30, 32) and the cooling air supply depending on a speed (n) and/or a torque (M) of the electric machine (14, 16).

摘要:
A drive train (10) for driving a motor vehicle has a combustion engine (12) for providing purely mechanical drive for the motor vehicle. A transmission (16) can be coupled to the combustion engine (12) via a shaft unit (14) for transmitting torque between the motor vehicle transmission (16) and the combustion engine (12). A reserve volume (18) is between the combustion engine (12) and the motor vehicle transmission (16) and is penetrated by the shaft unit (14). The reserve volume (18) can accommodate a high-voltage electric machine for purely electric drive of the motor vehicle or a low-voltage electric machine (32) for applying an electrically generated assistance torque to the motor vehicle transmission (16). As a result, a hybrid functionality can be made available to an at least limited degree, with the result that a cost-effective drive train (10) configured for a hybrid motor vehicle is made possible.

A drive train (6) is provided for a motor vehicle which can be driven in a purely electric manner. A gear mechanism (7, 15) has a standardized housing (8) for accommodating an electrical machine (16) or two electrical machines (10, 11) and for accommodating two gear mechanism output shafts (9) which are associated with a vehicle axle (2, 4). A large number of drive topologies for various vehicle sectors with purely electric drives can be formed by configuring the drive train in this way.
