发明名称	SPEED CHANGER OF HYDRAULIC DRIVING DEVICE AND CONTROL METHOD THEREOF
摘要	The speed changing appts. includes a hydraulic pump for supplying power to a variable capacity hydraulic motor (50). The pump and the motor are connected via a closed-centre switching valve. A sensor (63a) detects the selected position of a shift lever. Another sensor (52) determines the rotation speed of the hydraulic motor. A control device (6) determines whether the vehicle is braking or being powered, based on changes in position of the shift lever, and a comparison between the motor speed and a speed stored in memory.
