Abstract
The invention is characterized in that the expander is integrated into the secondary side of the transmission by means of one or more of the following features: the expander has a housing which substantially completely surrounds the expander; the expander is equipped with a drive shaft which projects out of the housing and has a coupling element that is fixed to the drive shaft and that produces a drive connection. The housing of the expander is mounted on the secondary side on the exterior of a transmission housing that surrounds the transmission, or is mounted from the exterior and partially inserted into the transmission housing, in such a way that the coupling element of the drive shaft projects into the transmission housing, producing a direct or indirect drive connection to the transmission output; the transmission has a heat exchanger, which is used to cool transmission oil for lubricating the transmission and/or actuating clutches or brakes inside the transmission, the working medium of the expander being conducted through the heat exchanger in such a way that heat is dissipated from the working medium to partially or completely condense the latter or that heat in the heat exchanger is transferred to the working medium of the expander to heat the latter.
