德國REXROTH比例閥價(jià)格實(shí)惠
REXROTH力士樂比例閥的工作原理如下:在不制動(dòng)時(shí),活塞在感載彈簧通過杠桿施加的推力F的作用下,處 于左端極限位置,這時(shí)閥門離開閥座打開,使輸入輸出油路相通。當(dāng)開始制動(dòng)時(shí),來自助力器的壓力為P1的制動(dòng)液由進(jìn)油口進(jìn)入,并通過閥門從出油口輸至后制動(dòng)管路.此時(shí)輸出液壓P,等于輸入液壓P1當(dāng)制動(dòng)踏板力增大時(shí),P1和P2同步增大。但由于活塞左側(cè)承壓面積大于右側(cè),致使活塞左側(cè)受到的力也大于右側(cè).
Rexroth力士樂比例閥的結(jié)構(gòu)和其它參數(shù)一定的情況下,調(diào)節(jié)作用的初始控制壓力P·的值取決于感載的比例閥感載彈簧預(yù)緊力的大小,其變化范圍在1.35~2.7MPa之I閏.因此只要使彈簧預(yù)緊力隨汽車實(shí)際軸荷的變化而變化,就能實(shí)現(xiàn)感載調(diào)節(jié)。感載比例閥安裝在左后輪附近,其安裝方式使得軸荷增加時(shí),感載彈簧被拉伸,折點(diǎn)液壓PS增大;軸荷減小時(shí).PS減小.這樣就使Ps隨載荷變化,實(shí)現(xiàn)了感載調(diào)節(jié),使前后輪制動(dòng)力分配更接近理想分配特性曲線。
力士樂Rexroth比例閥在使用過程中,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身落地,車輛空載,調(diào)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(diào)整方法.通過測量前后輪制動(dòng)管路壓力,繪制壓力分配特性曲線,確認(rèn)調(diào)整是否合格。
德國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。
