A drive train () for driving a motor vehicle has a combustion engine () for providing purely mechanical drive for the motor vehicle. A transmission () can be coupled to the combustion engine () via a shaft unit () for transmitting torque between the motor vehicle transmission () and the combustion engine (). A reserve volume () is between the combustion engine () and the motor vehicle transmission () and is penetrated by the shaft unit (). The reserve volume () can accommodate a high-voltage electric machine for purely electric drive of the motor vehicle or a low-voltage electric machine () for applying an electrically generated assistance torque to the motor vehicle transmission (). 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 () configured for a hybrid motor vehicle is made possible.

Drive train and method for operating a drive train

An arrangement () for driving a wheel of a motor vehicle has an electric machine () and a transmission (). The transmission () is downstream of the electric machine () and is arranged within the electric machine (). A common cooling device () with a cooling water jacket () is utilized for cooling both the electric machine () and the transmission ().

Arrangement of an electric machine and of a transmission connected downstream thereof

A component housing in a motor-vehicle drive train is sealed by pressurization of the housing interior. The component is a hybrid module () comprising at least one electric machine provided between the combustion engine (VM) and the gearing (G) of the motor-vehicle drive train. The pressurization is achieved by a rotating component (R, RA, M, F) of the hybrid module. The rotating component is designed in a manner similar to an impeller of a centrifugal pump. Therefore, rotation of the component builds up a positive pressure (P) on the radially outer region of the rotating component in the region of the housing (GE) in the interior of the hybrid module.

Device for sealing a component housing in a motor-vehicle drive train

A hybrid vehicle has an internal combustion engine, at least one electric drive motor and a starter. The internal combustion engine optionally can be started by the starter or the electric drive motor. However, the internal combustion engine is started by the starter when the vehicle is already being driven by the electric drive motor.
