REXROTH比例閥4WRA6E30-2X/G24K4/V現貨 力士樂比例閥當左側受力大于右側受力與感載彈簧預緊力之和時（此時的壓力為Ps）,活塞不斷右移,使閥門與閥座接觸而關閉,將輸入輸出油路隔絕,達到平衡狀態。P1若進一步升高時,則活塞左移,閥門再度打開,制動液流入出油口,使P2也升高。德國rexroth比例閥VT-NE30-2X的輸入壓力為零.即.;時,輸出腔的壓力通過比例閥皮圈凸筋間空酸從唇口泄去高壓,同時,當比例閥芯所受的彈簧力大于向右的液壓力時,比例閥彈簧將比例閥芯推回原始位置,使比例閥芯與比例閥皮圈內孔*分離而*泄壓.此時輸入輸出壓力為零.隨著輸入壓力.增大,即左增大,使比例滑閥單向力平衡遭破壞.當<>&;6-時,比例閥芯左移與比例閥皮圈產生間隙形成節流并混合比倒閥常見的故障為:1,輸入輸出壓力同步.2,低壓時輔人輸出壓力同步,高壓時輸入輸出壓力正常.3,低壓時輸入輸出壓力正常,高壓時輸入輸出壓力不正常.,1994.№為零時為混合比倒圉工作性能試驗示意圖.試驗時,先將管內的空氣排凈,然后分別取低,中,高三個壓力進行試驗,輸入輔出壓力符合即為合格。
Rexroth力士樂比例閥奧迪四輪驅動轎車制動系統在關閉ABS后,感載比例閥可用于防止后輪的過制動。當汽車直線行駛時,兩后輪的制動壓力可根據車輛載荷增減;當汽車左轉彎時,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壓力都下降.而當汽車右轉彎時,右后輪載荷減小,汽車的側向加速度使感載比例閥起作用,降低右后輪的制動壓力。這樣的自動調節使前、后輪的制動力分配和左、右后輪的制動力分配都接近理想的制動力分配,從而提高了制動安全性。0811404149 4WRPE 6 W2C32SJ-2X/G24K0/A1M-836

力士樂Rexroth比例閥在使用過程中,應注意對感載比例閥的檢查調整.當感載彈簧過松時,后輪制動力就會減小,此時應調整感載彈簧,但不可調得過緊,否則會使后輪制動力太大而失去側向控制能力,發生甩尾。正確的調整方法是.在平坦的地面上使車身落地,車輛空載,調整感載彈簧,使杠桿與活塞間無間隙即可.在有條件的情況下,可采用精確的調整方法.通過測量前后輪制動管路壓力,繪制壓力分配特性曲線,確認調整是否合格。 REXROTH比例閥4WRA6E30-2X/G24K4/V現貨
