力士樂Rexroth比例閥在使用過程中,應(yīng)注意對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,可采用準(zhǔn)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,較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。0811404977 4WRBKE35E1100SJ-1X/6ZG24EK31/A1D3M
