変速用油圧装置。 In a vehicle in which a master clutch consisting of a wet multi-disc clutch is interposed between the output side of the engine and the pump blade of the torque converter, and a plurality of speed clutches consisting of a wet multi-disc clutch are provided for the transmission, A plurality of switching valves for arbitrarily switching the plurality of speed clutches are hydraulically connected in parallel, and a clutch pack oil pressure sensor and a transmission output torque sensor for each of the plurality of speed clutches are connected in parallel. A control circuit is provided for controlling the switching valve based on the output signals of the oil pressure sensor and the torque sensor, and the control circuit is provided with a control circuit that controls the switching valve when the oil pressure sensor exceeds a set value and the torque exceeds a set value when the speed gear clutch is switched. A hydraulic system for shifting, characterized in that it is provided with a function of switching a switching valve that should be operated to an operating position and returning a switching valve that should be opened to an open position after a sensor determines that a set value has been exceeded.
