電液控制模塊總成簡介

電(dian)液控(kong)(kong)(kong)制(zhi)模(mo)塊總成(cheng)，電(dian)液控(kong)(kong)(kong)制(zhi)，是(shi)指在液壓傳(chuan)動與控(kong)(kong)(kong)制(zhi)中(zhong)，能夠(gou)接受(shou)(shou)模(mo)擬式(shi)或數(shu)字式(shi)信(xin)號，使輸(shu)出(chu)的流量或壓力邊續成(cheng)比例地受(shou)(shou)到控(kong)(kong)(kong)制(zhi)的一種控(kong)(kong)(kong)制(zhi)方法。 電(dian)液控(kong)(kong)(kong)制(zhi)模(mo)塊是(shi)控(kong)(kong)(kong)制(zhi)變速(su)器換擋(dang)而不是(shi)手動換擋(dang)的執(zhi)行單元(yuan)。

電液模塊損壞的癥狀

電液模塊損(sun)壞會(hui)讓(rang)車(che)動力下(xia)降加速(su)時(shi)加不起(qi)來(lai)油(you)。

以下是相關資料：

1、電(dian)(dian)(dian)(dian)液(ye)(ye)控(kong)制(zhi)(zhi)的(de)(de)組成：電(dian)(dian)(dian)(dian)液(ye)(ye)模塊中電(dian)(dian)(dian)(dian)液(ye)(ye)控(kong)制(zhi)(zhi)的(de)(de)組成元(yuan)(yuan)件有指(zhi)令(ling)元(yuan)(yuan)件、比較(jiao)元(yuan)(yuan)件、電(dian)(dian)(dian)(dian)控(kong)器(qi)(qi)、比例閥、液(ye)(ye)壓執行(xing)(xing)器(qi)(qi)等。指(zhi)令(ling)元(yuan)(yuan)件是給(gei)定(ding)控(kong)制(zhi)(zhi)信(xin)號的(de)(de)產生與輸入(ru)(ru)的(de)(de)元(yuan)(yuan)件。也可(ke)稱為編程器(qi)(qi)或(huo)輸入(ru)(ru)電(dian)(dian)(dian)(dian)路。在有反(fan)饋信(xin)號存在情況下它(ta)給(gei)出(chu)與反(fan)饋信(xin)號有相同(tong)形(xing)式和量(liang)級的(de)(de)控(kong)制(zhi)(zhi)信(xin)號。比較(jiao)元(yuan)(yuan)件的(de)(de)功(gong)用(yong)是把給(gei)定(ding)輸入(ru)(ru)與反(fan)饋信(xin)號進(jin)行(xing)(xing)比較(jiao)得出(chu)偏差信(xin)號作為電(dian)(dian)(dian)(dian)控(kong)器(qi)(qi)的(de)(de)輸入(ru)(ru)。電(dian)(dian)(dian)(dian)控(kong)器(qi)(qi)通(tong)常(chang)被稱作比例放大(da)器(qi)(qi)由于含在比例閥內的(de)(de)電(dian)(dian)(dian)(dian)磁鐵(tie)需要(yao)的(de)(de)控(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)流(liu)較(jiao)大(da)而偏差控(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)流(liu)較(jiao)小不足以推(tui)動電(dian)(dian)(dian)(dian)磁鐵(tie)工作。所以要(yao)對控(kong)制(zhi)(zhi)信(xin)號進(jin)行(xing)(xing)功(gong)率放大(da)。

2、電(dian)(dian)液(ye)控(kong)(kong)(kong)制(zhi)(zhi)的(de)工作(zuo)原(yuan)理：電(dian)(dian)液(ye)控(kong)(kong)(kong)制(zhi)(zhi)是指在液(ye)壓(ya)傳(chuan)動(dong)與(yu)控(kong)(kong)(kong)制(zhi)(zhi)中(zhong)能(neng)(neng)(neng)夠接(jie)受(shou)模擬式或數字式信號使輸出的(de)流(liu)量(liang)或壓(ya)力持(chi)續成比例地(di)受(shou)到控(kong)(kong)(kong)制(zhi)(zhi)的(de)一(yi)種控(kong)(kong)(kong)制(zhi)(zhi)方法。電(dian)(dian)液(ye)比例閥(fa)(fa)是介(jie)于開關型的(de)液(ye)壓(ya)閥(fa)(fa)與(yu)伺(si)(si)服(fu)閥(fa)(fa)之間的(de)一(yi)種液(ye)壓(ya)元件。與(yu)電(dian)(dian)液(ye)伺(si)(si)服(fu)閥(fa)(fa)相比其優(you)點(dian)是價廉、抗污染能(neng)(neng)(neng)力強。除去在控(kong)(kong)(kong)制(zhi)(zhi)精度及(ji)應(ying)(ying)快(kuai)速性方面還不如伺(si)(si)服(fu)閥(fa)(fa)外其它方面的(de)性能(neng)(neng)(neng)和控(kong)(kong)(kong)制(zhi)(zhi)水平與(yu)伺(si)(si)服(fu)閥(fa)(fa)的(de)相當。因此電(dian)(dian)液(ye)控(kong)(kong)(kong)制(zhi)(zhi)系(xi)統被廣泛應(ying)(ying)用(yong)于電(dian)(dian)液(ye)模塊。
