4WRPNH6C4B24L-2X/M/24PF6G力士樂閥

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,可采用準確的調整方法.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,較后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。
