電液控制模塊總成簡介

電液控(kong)制(zhi)(zhi)模(mo)塊(kuai)總成(cheng)，電液控(kong)制(zhi)(zhi)，是指(zhi)在液壓傳動與(yu)控(kong)制(zhi)(zhi)中，能(neng)夠(gou)接受模(mo)擬式或數字式信號，使(shi)輸出的流量或壓力邊(bian)續成(cheng)比例地受到控(kong)制(zhi)(zhi)的一種(zhong)控(kong)制(zhi)(zhi)方法。 電液控(kong)制(zhi)(zhi)模(mo)塊(kuai)是控(kong)制(zhi)(zhi)變速(su)器換(huan)擋而不是手動換(huan)擋的執行(xing)單(dan)元。

電液模塊損壞的癥狀

電液(ye)模(mo)塊損壞會讓(rang)車動(dong)力下降加速時加不起來油。

以下是相關資(zi)料：

1、電(dian)(dian)液(ye)(ye)控(kong)制(zhi)(zhi)的(de)(de)組成(cheng)：電(dian)(dian)液(ye)(ye)模塊(kuai)中電(dian)(dian)液(ye)(ye)控(kong)制(zhi)(zhi)的(de)(de)組成(cheng)元(yuan)(yuan)(yuan)件(jian)有指令(ling)元(yuan)(yuan)(yuan)件(jian)、比較(jiao)元(yuan)(yuan)(yuan)件(jian)、電(dian)(dian)控(kong)器(qi)(qi)、比例閥(fa)、液(ye)(ye)壓執行器(qi)(qi)等(deng)。指令(ling)元(yuan)(yuan)(yuan)件(jian)是給定控(kong)制(zhi)(zhi)信號(hao)(hao)的(de)(de)產生與輸(shu)(shu)入(ru)的(de)(de)元(yuan)(yuan)(yuan)件(jian)。也(ye)可稱為編程器(qi)(qi)或(huo)輸(shu)(shu)入(ru)電(dian)(dian)路(lu)。在有反饋信號(hao)(hao)存在情(qing)況下它給出(chu)(chu)與反饋信號(hao)(hao)有相同(tong)形式和(he)量級的(de)(de)控(kong)制(zhi)(zhi)信號(hao)(hao)。比較(jiao)元(yuan)(yuan)(yuan)件(jian)的(de)(de)功(gong)用(yong)是把給定輸(shu)(shu)入(ru)與反饋信號(hao)(hao)進行比較(jiao)得(de)出(chu)(chu)偏差信號(hao)(hao)作(zuo)為電(dian)(dian)控(kong)器(qi)(qi)的(de)(de)輸(shu)(shu)入(ru)。電(dian)(dian)控(kong)器(qi)(qi)通常被稱作(zuo)比例放大器(qi)(qi)由(you)于含在比例閥(fa)內(nei)的(de)(de)電(dian)(dian)磁(ci)鐵需要(yao)的(de)(de)控(kong)制(zhi)(zhi)電(dian)(dian)流較(jiao)大而偏差控(kong)制(zhi)(zhi)電(dian)(dian)流較(jiao)小不(bu)足以(yi)推動(dong)電(dian)(dian)磁(ci)鐵工作(zuo)。所以(yi)要(yao)對控(kong)制(zhi)(zhi)信號(hao)(hao)進行功(gong)率放大。

2、電(dian)液(ye)(ye)(ye)控(kong)(kong)(kong)(kong)制(zhi)的(de)(de)工作(zuo)原理：電(dian)液(ye)(ye)(ye)控(kong)(kong)(kong)(kong)制(zhi)是(shi)(shi)指在液(ye)(ye)(ye)壓(ya)傳動與控(kong)(kong)(kong)(kong)制(zhi)中能夠接受模擬式(shi)或(huo)數字式(shi)信號使輸出的(de)(de)流量(liang)或(huo)壓(ya)力持續成比(bi)例地受到控(kong)(kong)(kong)(kong)制(zhi)的(de)(de)一種控(kong)(kong)(kong)(kong)制(zhi)方(fang)法(fa)。電(dian)液(ye)(ye)(ye)比(bi)例閥是(shi)(shi)介于開關型的(de)(de)液(ye)(ye)(ye)壓(ya)閥與伺(si)服(fu)(fu)閥之間的(de)(de)一種液(ye)(ye)(ye)壓(ya)元件(jian)。與電(dian)液(ye)(ye)(ye)伺(si)服(fu)(fu)閥相比(bi)其優點是(shi)(shi)價廉、抗(kang)污(wu)染能力強。除去在控(kong)(kong)(kong)(kong)制(zhi)精(jing)度及應快速性方(fang)面還不如伺(si)服(fu)(fu)閥外其它方(fang)面的(de)(de)性能和(he)控(kong)(kong)(kong)(kong)制(zhi)水平與伺(si)服(fu)(fu)閥的(de)(de)相當。因此電(dian)液(ye)(ye)(ye)控(kong)(kong)(kong)(kong)制(zhi)系(xi)統被廣泛應用于電(dian)液(ye)(ye)(ye)模塊(kuai)。
