分析冷再生機(jī)的轉(zhuǎn)向液壓系統(tǒng)工作內(nèi)容

冷再生機(jī)采用前后車架鉸接相對偏轉(zhuǎn)實現(xiàn)整機(jī)轉(zhuǎn)向，該轉(zhuǎn)向系統(tǒng)的特點是操縱靈活輕便、工作可靠、結(jié)構(gòu)緊湊布置合理、維修保養(yǎng)方便。該系統(tǒng)由SNP3/38SSC07齒輪泵、單路穩(wěn)定分流閥、液壓轉(zhuǎn)向器和轉(zhuǎn)向油缸等液壓元件組成。下面冷再生機(jī)出租廠家來分析下冷再生機(jī)的轉(zhuǎn)向液壓系統(tǒng)工作內(nèi)容。
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.
系統(tǒng)工作原理是冷再生機(jī)直線行駛時油泵來的液壓油經(jīng)油管進(jìn)入單路穩(wěn)定分流閥，分流閥把液壓油分成兩路，一路流量恒定供轉(zhuǎn)向液壓系統(tǒng)用，另一路供輔助液壓系統(tǒng)用。此時方向盤處于中間位置，分流閥來的液壓油經(jīng)油管進(jìn)入轉(zhuǎn)向器，從回油口直接回到油箱中，轉(zhuǎn)向缸的兩腔處于封閉狀態(tài)。當(dāng)方向盤向左或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
右轉(zhuǎn)動時，分流閥過來的高壓油在轉(zhuǎn)向器中被分配到左右轉(zhuǎn)動液壓油缸中的有桿腔和無桿腔推動活塞實現(xiàn)轉(zhuǎn)向運(yùn)動。如果轉(zhuǎn)向系統(tǒng)壓力超過額定壓力10MPa則安全閥打開,溢流卸荷保護(hù)液壓元件;當(dāng)降至額定壓力時則安全閥關(guān)閉維持正常工作。
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.
轉(zhuǎn)向運(yùn)動中如轉(zhuǎn)向輪突遇較大外力超過15MPa時緩沖閥打開,溢流降壓從而避免高壓油對管路的破壞，與此同時轉(zhuǎn)向油缸外腔出現(xiàn)負(fù)壓，這時補(bǔ)油閥開啟，吸油迅速補(bǔ)入負(fù)壓腔,從而避免液壓沖擊、噪聲和氣蝕等。當(dāng)系統(tǒng)壓力超載時單向閥關(guān)閉，保護(hù)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.
轉(zhuǎn)向器具有液壓隨動轉(zhuǎn)作用，方向盤帶動液壓轉(zhuǎn)向器的閥芯轉(zhuǎn)過一一個角度后壓力油進(jìn)入轉(zhuǎn)閥，從轉(zhuǎn)閥進(jìn)入反饋馬達(dá)，后進(jìn)入轉(zhuǎn)向油缸，車輛出現(xiàn)一個相應(yīng)比例的轉(zhuǎn)向角，方向盤停止轉(zhuǎn)動則車輛作圓周運(yùn)動。
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.
