電液控制模塊總成簡介

電液控(kong)(kong)(kong)制(zhi)(zhi)(zhi)模(mo)(mo)塊總成，電液控(kong)(kong)(kong)制(zhi)(zhi)(zhi)，是(shi)指在液壓傳動(dong)與控(kong)(kong)(kong)制(zhi)(zhi)(zhi)中，能夠(gou)接受模(mo)(mo)擬式(shi)或(huo)數字式(shi)信(xin)號，使輸出的流量(liang)或(huo)壓力(li)邊(bian)續成比例地受到控(kong)(kong)(kong)制(zhi)(zhi)(zhi)的一種控(kong)(kong)(kong)制(zhi)(zhi)(zhi)方法。 電液控(kong)(kong)(kong)制(zhi)(zhi)(zhi)模(mo)(mo)塊是(shi)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)變(bian)速器換擋而不是(shi)手(shou)動(dong)換擋的執行單元。

電液模塊損壞的癥狀

電液模塊(kuai)損壞會讓車動力(li)下(xia)降加(jia)(jia)速時加(jia)(jia)不起來油。

以下(xia)是相(xiang)關(guan)資(zi)料(liao)：

1、電液控(kong)制(zhi)(zhi)的(de)組(zu)成(cheng)：電液模塊中電液控(kong)制(zhi)(zhi)的(de)組(zu)成(cheng)元(yuan)件(jian)有指令元(yuan)件(jian)、比(bi)較元(yuan)件(jian)、電控(kong)器(qi)、比(bi)例(li)(li)閥、液壓(ya)執(zhi)行(xing)(xing)器(qi)等(deng)。指令元(yuan)件(jian)是給(gei)定控(kong)制(zhi)(zhi)信(xin)(xin)(xin)(xin)號的(de)產生與(yu)(yu)輸(shu)入的(de)元(yuan)件(jian)。也可稱為編程器(qi)或輸(shu)入電路(lu)。在(zai)有反饋(kui)信(xin)(xin)(xin)(xin)號存在(zai)情況下它給(gei)出與(yu)(yu)反饋(kui)信(xin)(xin)(xin)(xin)號有相同(tong)形式和量級的(de)控(kong)制(zhi)(zhi)信(xin)(xin)(xin)(xin)號。比(bi)較元(yuan)件(jian)的(de)功用(yong)是把給(gei)定輸(shu)入與(yu)(yu)反饋(kui)信(xin)(xin)(xin)(xin)號進(jin)行(xing)(xing)比(bi)較得出偏差信(xin)(xin)(xin)(xin)號作為電控(kong)器(qi)的(de)輸(shu)入。電控(kong)器(qi)通常被稱作比(bi)例(li)(li)放大(da)器(qi)由于含在(zai)比(bi)例(li)(li)閥內的(de)電磁鐵需要的(de)控(kong)制(zhi)(zhi)電流較大(da)而偏差控(kong)制(zhi)(zhi)電流較小不足以推(tui)動電磁鐵工作。所以要對控(kong)制(zhi)(zhi)信(xin)(xin)(xin)(xin)號進(jin)行(xing)(xing)功率放大(da)。

2、電液(ye)(ye)(ye)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)的工作原(yuan)理(li)：電液(ye)(ye)(ye)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)是(shi)指在(zai)液(ye)(ye)(ye)壓傳(chuan)動與控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)中能(neng)(neng)夠接受模擬式(shi)或數字式(shi)信號使(shi)輸出的流(liu)量或壓力持續成比例(li)地受到控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)的一種控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)方(fang)法。電液(ye)(ye)(ye)比例(li)閥(fa)是(shi)介(jie)于(yu)開(kai)關型的液(ye)(ye)(ye)壓閥(fa)與伺服(fu)閥(fa)之(zhi)間的一種液(ye)(ye)(ye)壓元件(jian)。與電液(ye)(ye)(ye)伺服(fu)閥(fa)相(xiang)比其(qi)優(you)點是(shi)價(jia)廉、抗污染能(neng)(neng)力強(qiang)。除去在(zai)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)精度及(ji)應快速性方(fang)面(mian)還不如伺服(fu)閥(fa)外其(qi)它方(fang)面(mian)的性能(neng)(neng)和控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)水(shui)平與伺服(fu)閥(fa)的相(xiang)當(dang)。因此電液(ye)(ye)(ye)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)系統(tong)被廣泛應用于(yu)電液(ye)(ye)(ye)模塊。
