力士樂REXROTH比例閥4WRD系列
REXROTH比例閥有兩個腔,分別裝有活塞和閥門,閥門兩端有兩個腔,其中右腔和進油口相通,井通過油管與主缸出油口相連;左腔與出油口相通,并通過管路和后輪制動管路相連。比例閥的工作原理如下:在不制動時,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,這時閥門離開閥座打開,使輸入輸出油路相通。
Rexroth比例閥利用車身與車橋之間的距離變化(外界作用力)來改變彈簧的預緊力,隨著車輛載荷的增加,相應地進行調整,使得在任何載荷條件下都能得到一個近似理想的制動力分配。它安裝在制動總泵與后輪制動分泵之間的管道上,由殼體、柱塞、閥門、彈簧等組成。殼體進油孔與制動總泵出油孔相通,出油孔與車輪制動分泵相通。當外界作用力小時,感載比例閥的柱塞在彈簧預緊力的作用下被推至zui右邊,兩孔相通,總泵與分泵壓力相等。當外界作用力大于彈簧預緊力,迫使柱塞左移,令柱塞與閥門接觸并關閉了閥門,切斷總泵通向分泵的通道;若外界作用力壓力繼續增大,又會使柱塞右移,柱塞與閥門脫離接觸,閥門又被打開,總泵與分泵又相通。這樣比例閥反復動作使分泵的液壓不斷得到調整,也即不斷調整了后輪制動力。比例閥來調節所需要的流量。這種傳統的氣動控制系統要想要有多個輸出力和多個運動速度,就需要多個減壓閥、節流閥及換向閥。這樣,不僅元件需要多,成本高,構成系統復雜,且許多元件都需要預良好行人工調節。電氣比例閥控制屬于連續控制,其特點是輸出量隨輸入量的變化而變化,輸出量與輸入量之間存在一定的比例關系。比例控制有開環控制和閉環控制之分。
力士樂4WRD...XN 型閥是一種通過電磁鐵操縱的 3 檔式調節方向閥。它適用于在對動態和靈敏度方面有較高要求的情況下調節位置、速度、壓力以及力。它適用于指令 94/9/EC 規定的有爆炸危險的場所。
