電液控制模塊總成簡介

電(dian)液控制(zhi)模塊總(zong)成，電(dian)液控制(zhi)，是(shi)指在液壓傳(chuan)動與控制(zhi)中，能夠接受(shou)模擬式或(huo)數字式信(xin)號(hao)，使輸出(chu)的(de)流量或(huo)壓力(li)邊續(xu)成比(bi)例(li)地受(shou)到控制(zhi)的(de)一種控制(zhi)方法。 電(dian)液控制(zhi)模塊是(shi)控制(zhi)變(bian)速器換擋(dang)而不是(shi)手動換擋(dang)的(de)執行單元。

電液模塊損壞的癥狀

電液(ye)模塊損壞會讓車(che)動力下(xia)降加速時加不起來油(you)。

以(yi)下(xia)是(shi)相關資(zi)料(liao)：

1、電(dian)(dian)液(ye)(ye)控(kong)(kong)制(zhi)的(de)(de)(de)組成：電(dian)(dian)液(ye)(ye)模塊中(zhong)電(dian)(dian)液(ye)(ye)控(kong)(kong)制(zhi)的(de)(de)(de)組成元件(jian)(jian)有指令元件(jian)(jian)、比較(jiao)(jiao)元件(jian)(jian)、電(dian)(dian)控(kong)(kong)器、比例閥(fa)、液(ye)(ye)壓(ya)執行器等。指令元件(jian)(jian)是給定(ding)控(kong)(kong)制(zhi)信(xin)號(hao)(hao)的(de)(de)(de)產生(sheng)與(yu)輸(shu)(shu)入的(de)(de)(de)元件(jian)(jian)。也可稱(cheng)為編(bian)程器或輸(shu)(shu)入電(dian)(dian)路(lu)。在有反饋信(xin)號(hao)(hao)存在情(qing)況下它(ta)給出(chu)與(yu)反饋信(xin)號(hao)(hao)有相(xiang)同形式和量級的(de)(de)(de)控(kong)(kong)制(zhi)信(xin)號(hao)(hao)。比較(jiao)(jiao)元件(jian)(jian)的(de)(de)(de)功(gong)用是把給定(ding)輸(shu)(shu)入與(yu)反饋信(xin)號(hao)(hao)進(jin)行比較(jiao)(jiao)得(de)出(chu)偏差信(xin)號(hao)(hao)作(zuo)(zuo)為電(dian)(dian)控(kong)(kong)器的(de)(de)(de)輸(shu)(shu)入。電(dian)(dian)控(kong)(kong)器通常被(bei)稱(cheng)作(zuo)(zuo)比例放大器由于含(han)在比例閥(fa)內(nei)的(de)(de)(de)電(dian)(dian)磁鐵需要的(de)(de)(de)控(kong)(kong)制(zhi)電(dian)(dian)流(liu)較(jiao)(jiao)大而偏差控(kong)(kong)制(zhi)電(dian)(dian)流(liu)較(jiao)(jiao)小不(bu)足以推(tui)動電(dian)(dian)磁鐵工(gong)作(zuo)(zuo)。所以要對控(kong)(kong)制(zhi)信(xin)號(hao)(hao)進(jin)行功(gong)率放大。

2、電(dian)(dian)液(ye)控(kong)(kong)制(zhi)(zhi)(zhi)的(de)(de)(de)工作原理：電(dian)(dian)液(ye)控(kong)(kong)制(zhi)(zhi)(zhi)是指在(zai)液(ye)壓(ya)傳動與控(kong)(kong)制(zhi)(zhi)(zhi)中能夠接受模(mo)擬式(shi)或數(shu)字式(shi)信號使輸(shu)出的(de)(de)(de)流量(liang)或壓(ya)力持續(xu)成比(bi)(bi)(bi)例(li)地受到控(kong)(kong)制(zhi)(zhi)(zhi)的(de)(de)(de)一(yi)種(zhong)(zhong)控(kong)(kong)制(zhi)(zhi)(zhi)方法。電(dian)(dian)液(ye)比(bi)(bi)(bi)例(li)閥是介于(yu)開關型(xing)的(de)(de)(de)液(ye)壓(ya)閥與伺(si)服閥之間的(de)(de)(de)一(yi)種(zhong)(zhong)液(ye)壓(ya)元件。與電(dian)(dian)液(ye)伺(si)服閥相比(bi)(bi)(bi)其優點是價(jia)廉、抗污染能力強。除去(qu)在(zai)控(kong)(kong)制(zhi)(zhi)(zhi)精度及應快速性(xing)方面(mian)還不(bu)如伺(si)服閥外其它方面(mian)的(de)(de)(de)性(xing)能和控(kong)(kong)制(zhi)(zhi)(zhi)水平與伺(si)服閥的(de)(de)(de)相當。因此電(dian)(dian)液(ye)控(kong)(kong)制(zhi)(zhi)(zhi)系統被廣泛應用于(yu)電(dian)(dian)液(ye)模(mo)塊。
