3DREP6型三通減壓閥由比例電磁鐵直接驅(qū)動(dòng),
將輸入的電信號(hào)按比例地轉(zhuǎn)化成壓力輸出信號(hào).
比例電磁鐵是帶中心螺紋和可更換線圈的濕式可控直流電磁鐵,
電磁鐵可通過(guò)外部電控器(3DREP型)和集成電控器(3DREPE型)精細(xì)控制
REXROTH力士樂(lè)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(guò)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(mén)離開(kāi)閥座打開(kāi),使輸入輸出油路相通。當(dāng)開(kāi)始制動(dòng)時(shí),來(lái)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(guò)閥門(mén)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(lè)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
