A flexible drive device comprising an incorporated hydraulic transmission provides either a classic drive or a relatively high-speed hydraulic drive and enables the thermal motor, which drives only the hydraulic pump, to rotate at constant speed. It also ensures normal supercharging of the engine at low and medium speeds. A first embodiment of the device comprises two input shafts (8, 9), two output shafts (11, 12), two intermediate shafts (13, 14) a secondary output shaft (10), a hydraulic pump (5), a secondary drive shaft (15), a secondary clutch (6), a hydraulic motor (7), and an auxiliary supercharging device (not shown). When the driver establishes the hydraulic connection of the device, the hydraulic motor (7) drives the gearbox (4) by means of the clutch (6) and a mechanical transmission connecting the shafts (12, 15). The device can be used to drive passenger cars and commercial vehicles. |
