According to an illustrative example of the present invention, an internal combustion engine is provided with a gear box. This gear box is driven by an end portion of the crank shaft. A belt pulley is provided around the axis of the gearbox. The belt pulley drives through a belt an electric power generator. The gear box contains a planetary gear of variable transmission ratio. The change of transmission ratio is effected by an hydraulically operated clutch. The hydraulically operated clutch is actuated by a hydraulic actuating device. The hydraulic actuating device is actuated by oil pressure. The oil pressure is obtained by a hydraulic pump integrated into the gear box. Further components of the circuitry containing the pump and the hydraulic actuating device are provided outside the gear box. These external components are carried by a carrier plate. This carrier plate contains side by side channels of the hydraulic circuitry. Simultaneously, the carrier plate acts as a torque support for the gear box which is mounted on the end portion of the crank shaft.
