Abstract

PURPOSE: To simplify the construction and promte the operational efficiency in a captioned device by constructing an output/input closed oil-pressure circuit for every oil-pressure motor for wheel driving and arranging a pair of these circuits in parallel for connecting both circuits via a connecting circuit provided with a fixed switch valve.
CONSTITUTION: Output/input closed oil-pressure circuits 5 and 6 of variable-capacity type oil-pressure pump 3 and 4 driven for rotation by a proper drive source are respectively provided with regular/reverse rotation type oil-pressure motors 7 and 8 for constructing a pair of oil-pressure drive circuits. In these oil-pressure drive circuits, short-circuit routes 5', 6', and 5", 6" are respectively connected to pumps 3 and 4 in parallel, and connection route 13 and 14 are connected between these short- circuit routes 5'W6". The connection route 13 and 14 are connected to an auxiliary pump 2, and also to a tank 1 via a relief valve 12, while relief valves 9 and 10 are respectively provided in the connection route 13 and 14. Meanwhile, connecting circuits 15 and 16 are provided between both oil-pressure drive circuits with a three- position switch valve 11.
