The cold regeneration machine uses the front and rear frame hinge to realize the whole machine steering. The steering system is characterized by flexible and light operation, reliable work, compact structure, reasonable layout and convenient maintenance. The system is composed of SNP3/38SSC07 gear pump, one-way stable diverter valve, hydraulic steering gear, steering cylinder and other hydraulic components. The work content of the steering hydraulic system of the down cooling regenerator is analyzed as follows.

系统工作原理是冷再生机直线行驶时油泵来的液压油经油管进入单路稳定分流阀，分流阀把液压油分成两路，一路流量恒定供转向液压系统用，另一路供辅助液压系统用。此时方向盘处于中间位置，分流阀来的液压油经油管进入转向器，从回油口直接回到油箱中，转向缸的两腔处于封闭状态。当方向盘向左或323

The working principle of the system is that the hydraulic oil from the oil pump of the cold regenerator enters the single stable diverter valve through the oil pipe when it runs in a straight line. The diverter valve divides the hydraulic oil into two paths, one for the steering hydraulic system with constant flow, and the other for the auxiliary hydraulic system. At this time, the steering wheel is in the middle position, the hydraulic oil from the diverter valve enters the steering gear through the oil pipe, returns directly to the oil tank from the oil return port, and the two chambers of the steering cylinder are closed. When the steering wheel is left or 323

右转动时，分流阀过来的高压油在转向器中被分配到左右转动液压油缸中的有杆腔和无杆腔推动活塞实现转向运动。如果转向系统压力超过额定压力10MPa则阀打开,溢流卸荷保护液压元件;当降额定压力时则阀关闭维持正常工作。

When turning to the right, the high-pressure oil from the diverter valve is distributed in the steering gear to the rod cavity and the rod cavity in the left and right rotating hydraulic cylinders to push the piston to achieve steering movement. If the pressure of the steering system exceeds the rated pressure by 10MPa, the safety valve will be opened and the overflow unloading will protect the hydraulic components; When the pressure drops to the rated pressure, the safety valve will be closed and maintain normal operation.

转向运动中如转向轮突遇较大外力超过15MPa时缓冲阀打开,溢流降压从而避免高压油对管路的破坏，与此同时转向油缸外腔出现负压，这时补油阀开启，吸油迅速补入负压腔,从而避免液压冲击、噪声和气蚀等。当系统压力超载时单向阀关闭，保护前面的油管及元件。

During the steering movement, if the steering wheel suddenly encounters a large external force exceeding 15MPa, the buffer valve will be opened, and the overflow pressure will be reduced to avoid the damage of high-pressure oil to the pipeline. At the same time, there will be negative pressure in the outer chamber of the steering cylinder. At this time, the oil make-up valve will be opened, and the suction oil will be quickly added into the negative pressure chamber to avoid hydraulic shock, noise, cavitation, etc. When the system pressure is overloaded, the check valve is closed to protect the oil pipe and components in front.

转向器具有液压随动转作用，方向盘带动液压转向器的阀芯转过一一个角度后压力油进入转阀，从转阀进入反馈马达，后进入转向油缸，车辆出现一个相应比例的转向角，方向盘停止转动则车辆作圆周运动。

The steering gear has the hydraulic servo function. The steering wheel drives the valve core of the hydraulic steering gear to rotate through one angle, and then the pressure oil enters the rotary valve. From the rotary valve, it enters the feedback motor, and then the steering cylinder. The vehicle has a corresponding steering angle. When the steering wheel stops rotating, the vehicle moves in a circle.
