The travel motor is equipped with high pressure automatic variable equipment. When the high gear is engaged, the control circuit receives oil from the manual speed regulating oil hole to push the speed regulating valve to offset, so that the motor becomes small displacement; If the increase of friction resistance causes the hydraulic pressure to rise to the preset value, the gear oil pushes the speed control valve to the right, and the motor automatically changes to a large displacement low-speed gear to increase torque. So this kind of motor can
