電液控制模塊總成簡介

電液控(kong)制(zhi)模(mo)塊(kuai)總成(cheng)，電液控(kong)制(zhi)，是指在液壓(ya)傳動與控(kong)制(zhi)中，能夠接受(shou)模(mo)擬式(shi)或數字式(shi)信號，使輸出的(de)(de)流量或壓(ya)力邊續成(cheng)比例地受(shou)到控(kong)制(zhi)的(de)(de)一種控(kong)制(zhi)方法。 電液控(kong)制(zhi)模(mo)塊(kuai)是控(kong)制(zhi)變速器換擋而不是手動換擋的(de)(de)執(zhi)行單元(yuan)。

電液模塊損壞的癥狀

電(dian)液模(mo)塊(kuai)損壞會讓車動力(li)下降加速時加不起來油。

以下(xia)是相關資(zi)料(liao)：

1、電液控(kong)(kong)制(zhi)(zhi)的(de)組成(cheng)(cheng)：電液模塊中電液控(kong)(kong)制(zhi)(zhi)的(de)組成(cheng)(cheng)元(yuan)件有指(zhi)令元(yuan)件、比較元(yuan)件、電控(kong)(kong)器(qi)(qi)、比例閥、液壓執行(xing)(xing)器(qi)(qi)等。指(zhi)令元(yuan)件是給定(ding)(ding)控(kong)(kong)制(zhi)(zhi)信號(hao)(hao)的(de)產生與輸(shu)入的(de)元(yuan)件。也可稱為(wei)編(bian)程器(qi)(qi)或輸(shu)入電路。在(zai)有反(fan)饋信號(hao)(hao)存(cun)在(zai)情況下(xia)它給出與反(fan)饋信號(hao)(hao)有相同形式和量級的(de)控(kong)(kong)制(zhi)(zhi)信號(hao)(hao)。比較元(yuan)件的(de)功(gong)用是把給定(ding)(ding)輸(shu)入與反(fan)饋信號(hao)(hao)進(jin)行(xing)(xing)比較得出偏(pian)差信號(hao)(hao)作為(wei)電控(kong)(kong)器(qi)(qi)的(de)輸(shu)入。電控(kong)(kong)器(qi)(qi)通常(chang)被稱作比例放大器(qi)(qi)由于含(han)在(zai)比例閥內的(de)電磁鐵(tie)需要的(de)控(kong)(kong)制(zhi)(zhi)電流較大而偏(pian)差控(kong)(kong)制(zhi)(zhi)電流較小不足以(yi)推動電磁鐵(tie)工作。所以(yi)要對控(kong)(kong)制(zhi)(zhi)信號(hao)(hao)進(jin)行(xing)(xing)功(gong)率放大。

2、電(dian)液(ye)(ye)(ye)(ye)控(kong)制(zhi)(zhi)(zhi)的工作原理：電(dian)液(ye)(ye)(ye)(ye)控(kong)制(zhi)(zhi)(zhi)是指(zhi)在液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)傳動與(yu)(yu)(yu)控(kong)制(zhi)(zhi)(zhi)中能夠接受模擬式(shi)或數字式(shi)信號(hao)使(shi)輸出(chu)的流(liu)量(liang)或壓(ya)(ya)(ya)力持(chi)續成比(bi)例地受到(dao)控(kong)制(zhi)(zhi)(zhi)的一(yi)(yi)種(zhong)控(kong)制(zhi)(zhi)(zhi)方(fang)法。電(dian)液(ye)(ye)(ye)(ye)比(bi)例閥(fa)是介于(yu)(yu)開(kai)關(guan)型的液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)閥(fa)與(yu)(yu)(yu)伺服(fu)閥(fa)之間的一(yi)(yi)種(zhong)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)元件。與(yu)(yu)(yu)電(dian)液(ye)(ye)(ye)(ye)伺服(fu)閥(fa)相比(bi)其優(you)點(dian)是價(jia)廉、抗污染能力強。除去在控(kong)制(zhi)(zhi)(zhi)精度及應快速性方(fang)面(mian)還(huan)不如伺服(fu)閥(fa)外其它(ta)方(fang)面(mian)的性能和(he)控(kong)制(zhi)(zhi)(zhi)水平與(yu)(yu)(yu)伺服(fu)閥(fa)的相當。因此電(dian)液(ye)(ye)(ye)(ye)控(kong)制(zhi)(zhi)(zhi)系統被廣泛(fan)應用于(yu)(yu)電(dian)液(ye)(ye)(ye)(ye)模塊(kuai)。
