REXROTH比例閥4WRA6E30-2X/G24K4/V現(xiàn)貨                                                                          力士樂(lè)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,使閥門(mén)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(mén)再度打開(kāi),制動(dòng)液流入出油口,使P2也升高。德國(guó)rexroth比例閥VT-NE30-2X的輸入壓力為零.即.;時(shí),輸出腔的壓力通過(guò)比例閥皮圈凸筋間空酸從唇口泄去高壓,同時(shí),當(dāng)比例閥芯所受的彈簧力大于向右的液壓力時(shí),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(nèi)孔*分離而*泄壓.此時(shí)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(dāng)<>&;6-時(shí),比例閥芯左移與比例閥皮圈產(chǎn)生間隙形成節(jié)流并混合比倒閥常見(jiàn)的故障為:1,輸入輸出壓力同步.2,低壓時(shí)輔人輸出壓力同步,高壓時(shí)輸入輸出壓力正常.3,低壓時(shí)輸入輸出壓力正常,高壓時(shí)輸入輸出壓力不正常.,1994.№為零時(shí)為混合比倒圉工作性能試驗(yàn)示意圖.試驗(yàn)時(shí),先將管內(nèi)的空氣排凈,然后分別取低,中,高三個(gè)壓力進(jìn)行試驗(yàn),輸入輔出壓力符合即為合格。
　　Rexroth力士樂(lè)比例閥奧迪四輪驅(qū)動(dòng)轎車(chē)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(guò)制動(dòng)。當(dāng)汽車(chē)直線(xiàn)行駛時(shí),兩后輪的制動(dòng)壓力可根據(jù)車(chē)輛載荷增減;當(dāng)汽車(chē)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(chē)右轉(zhuǎn)彎時(shí),右后輪載荷減小,汽車(chē)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。0811404149 4WRPE 6 W2C32SJ-2X/G24K0/A1M-836

力士樂(lè)Rexroth比例閥在使用過(guò)程中,應(yīng)注意對(duì)感載比例閥的檢查調(diào)整.當(dāng)感載彈簧過(guò)松時(shí),后輪制動(dòng)力就會(huì)減小,此時(shí)應(yīng)調(diào)整感載彈簧,但不可調(diào)得過(guò)緊,否則會(huì)使后輪制動(dòng)力太大而失去側(cè)向控制能力,發(fā)生甩尾。正確的調(diào)整方法是.在平坦的地面上使車(chē)身落地,車(chē)輛空載,調(diào)整感載彈簧,使杠桿與活塞間無(wú)間隙即可.在有條件的情況下,可采用精確的調(diào)整方法.通過(guò)測(cè)量前后輪制動(dòng)管路壓力,繪制壓力分配特性曲線(xiàn),確認(rèn)調(diào)整是否合格。                                                                                                                       REXROTH比例閥4WRA6E30-2X/G24K4/V現(xiàn)貨
