德國(guó)Rexroth力士樂比例閥的工作原理，REXROTH力士樂比例閥結(jié)構(gòu)，力士樂比例閥作用
REXROTH力士樂比例閥當(dāng)左側(cè)受力大于右側(cè)受力與感載彈簧預(yù)緊力之和時(shí)（此時(shí)的壓力為Ps）,活塞不斷右移,zui后使閥門與閥座接觸而關(guān)閉,將輸入輸出油路隔絕,達(dá)到平衡狀態(tài)。P1若進(jìn)一步升高時(shí),則活塞左移,閥門再度打開,制動(dòng)液流入出油口,使P2也升高。Rexroth力士樂比例閥奧迪四輪驅(qū)動(dòng)轎車制動(dòng)系統(tǒng)在關(guān)閉ABS后,感載比例閥可用于防止后輪的過制動(dòng)。當(dāng)汽車直線行駛時(shí),兩后輪的制動(dòng)壓力可根據(jù)車輛載荷增減;當(dāng)汽車左轉(zhuǎn)彎時(shí),左后輪載荷下降,由于感載比例閥位于左后輪附近,可同樣起作用使兩后輪的制動(dòng)壓力都下降.而當(dāng)汽車右轉(zhuǎn)彎時(shí),右后輪載荷減小,汽車的側(cè)向加速度使感載比例閥起作用,降低右后輪的制動(dòng)壓力。這樣的自動(dòng)調(diào)節(jié)使前、后輪的制動(dòng)力分配和左、右后輪的制動(dòng)力分配都接近理想的制動(dòng)力分配,從而提高了制動(dòng)安全性。
