PROBLEM TO BE SOLVED: To provide a hydraulic pump driving device which drives one hydraulic pump with the power of an engine 3 and an electric motor 4. SOLUTION: This hydraulic pump driving device is provided with input shafts 1a and 2a, output shafts 1b and 2b, and a first one-way clutch 1 and a second one-way clutch 2 transmitting the power from the input shaft to the output shaft direction only when the rotation of the input shaft is higher than the rotation of the output shaft. The engine 3 is connected to the input shaft 1a of the first one-way clutch 1, and the electric motor 4 is connected to the input shaft 2a of the second one-way clutch 2. The hydraulic pump 5 is connected to the output shaft 1b or 2b of the first one-way clutch 1 or the second one-way clutch 2. The output shafts 1b and 2b are connected to each other with connection means 1f and 2f. The hydraulic pump 5 is rotated and driven by the engine 3 or the electric motor 4. COPYRIGHT: (C)2003,JPO |
