<p>A hydrostatic transmission (1, 2, 3, 4) with a pair of pump/motor units (1, 2) connected in a closed loop state by a hydrostatic circuit (3, 4). The hydrostatic transmission comprises a differential pressure detecting means (11) which detects the differential pressure between the circuits lines (3, 4) and a displacement correcting means (12) which, in case an operation to establish a neutral status has been carried out, controls the displacement volume of the pumping pump/motor units (1, 2), toward a direction in which the magnitude of this differential pressure is held within a set range. In case the range is set to a value with which a vehicle cannot run, the phenomenon of creep running will not occur.</p> |
