走行速度切換装置。 The left and right crawlers and other traveling means are connected to separate variable displacement hydraulic motors, and the displacement of each hydraulic motor is controlled by a displacement control cylinder to control the traveling speed. A switching valve is provided in each of the capacity control cylinders to selectively connect one chamber between the tank and the operating circuit of the operating motor of the hydraulic motor to control the capacity of the hydraulic motor to a maximum or minimum. An automatic switching valve is interposed between the switching valve and the operating circuit to connect the switching circuit to the operating circuit when the pressure in the operating circuit is low, but to connect the connecting circuit to the tank when the pressure is high. , a sensor is provided to detect the switching operation of the automatic switching valve, and another switching valve is connected to the sensor so that when the sensor detects the switching operation, the switching valve performs the switching operation to minimize the capacity of the hydraulic motor. A traveling speed switching device that is connected.
