<p>PROBLEM TO BE SOLVED: To provide an oil pressure generating source to generate a specified pressure both during forward run and during reversing and normally operate a hydraulic clutch. SOLUTION: Two hydraulic pumps P1 and P2 are mounted on the outer periphery of a hydraulic clutch containing case 14 and the hydraulic pumps P1 and P2 generate an oil pressure when a main electric motor is run. A one- way clutch 20 is incorporated in a hydraulic pump gear 17, two oil pressure pumps P1 and P2 the working rotation directions of which are reverse to each other are used. By effectively utilizing the function of the one-way clutch 20, both forward run and reversing are usable.</p> |
