<p>The device consists of two hydraulic pumps/motors with adjustable displacement (1 and 2) connected in a closed hydraulic system. The system includes oil accumulators on each side of the hydraulic pumps/motors with adjustable displacement. There are 'pumps', valves and check valves to compensate for leakage of oil. In the system there is a valve (8) to change the inlet and outlet of the hydraulic pumps/motors with adjustable displacement. The hydraulic pumps/motors with adjustable displacement are 'flanged' to the rotor of an electrical motor in such a way that their shafts (3 and 4) are the 'shaft' of the rotor (6). The device forms within the rotor of an electrical motor a power unit (device), which consists of an electrical motor, a differential and facilities for changing the direction of rotation of the shafts. The device can be used for instance by a vehicle.</p> |
