扭矩傳感器簡介

在方向(xiang)盤下(xia)邊的(de)方向(xiang)桿上找到助(zhu)力(li)電(dian)機，電(dian)機上一(yi)般有一(yi)個(ge)小鐵蓋(gai)護著的(de)、帶(dai)(dai)四根線（帶(dai)(dai)有一(yi)個(ge)插頭）的(de)就(jiu)是轉向(xiang)助(zhu)力(li)扭矩(ju)傳感(gan)器，拆下(xia)小鐵蓋(gai)就(jiu)能看(kan)到。

電動(dong)助(zhu)力(li)轉(zhuan)向(xiang)(xiang)系(xi)統(tong)主(zhu)要由(you)扭矩傳(chuan)感(gan)器(qi)，車(che)速(su)傳(chuan)感(gan)器(qi)，電動(dong)機，減(jian)速(su)機構與電子控制單元(yuan)等組成。該系(xi)統(tong)通過(guo)(guo)(guo)扭矩傳(chuan)感(gan)器(qi)感(gan)知駕(jia)駛員在轉(zhuan)向(xiang)(xiang)操作時方向(xiang)(xiang)盤產生的扭矩力(li)和轉(zhuan)向(xiang)(xiang)角度，就會把操控信息轉(zhuan)換成數字信號輸入到控制單元(yuan)，再(zai)經過(guo)(guo)(guo)控制單元(yuan)對這些信號進行運算(suan)得到一(yi)個最(zui)佳的力(li)矩最(zui)后控制驅使電動(dong)機工(gong)作。以上就是整個電動(dong)助(zhu)力(li)系(xi)統(tong)構成和工(gong)作的過(guo)(guo)(guo)程，不(bu)難看出扭矩傳(chuan)感(gan)器(qi)在電動(dong)助(zhu)力(li)系(xi)統(tong)中是最(zui)為重(zhong)要的器(qi)件(jian)之一(yi)。

扭矩傳感器的作用

扭矩傳(chuan)感器(qi)在電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)助(zhu)(zhu)力(li)轉(zhuan)向(xiang)(xiang)(xiang)系(xi)統(tong)(tong)(tong)(tong)中的(de)(de)(de)(de)作用(yong)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)助(zhu)(zhu)力(li)轉(zhuan)向(xiang)(xiang)(xiang)系(xi)統(tong)(tong)(tong)(tong)可以(yi)稱之為EPS，它(ta)就是一種(zhong)直接依靠(kao)電(dian)(dian)(dian)機(ji)提供輔(fu)助(zhu)(zhu)扭矩的(de)(de)(de)(de)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)轉(zhuan)向(xiang)(xiang)(xiang)系(xi)統(tong)(tong)(tong)(tong)。在整(zheng)個系(xi)統(tong)(tong)(tong)(tong)中，扭矩傳(chuan)感器(qi)起(qi)(qi)到(dao)決定性作用(yong)。與傳(chuan)統(tong)(tong)(tong)(tong)的(de)(de)(de)(de)液(ye)(ye)壓(ya)助(zhu)(zhu)力(li)轉(zhuan)向(xiang)(xiang)(xiang)系(xi)統(tong)(tong)(tong)(tong)不(bu)同(tong)(tong)的(de)(de)(de)(de)是電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)助(zhu)(zhu)力(li)轉(zhuan)向(xiang)(xiang)(xiang)系(xi)統(tong)(tong)(tong)(tong)具有(you)性能應用(yong)上更大的(de)(de)(de)(de)優(you)勢。它(ta)不(bu)光(guang)在需要轉(zhuan)向(xiang)(xiang)(xiang)時才(cai)啟動(dong)(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)機(ji)產生助(zhu)(zhu)力(li)，這樣能大大的(de)(de)(de)(de)減少發(fa)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)燃油消(xiao)耗。電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)助(zhu)(zhu)力(li)能在各種(zhong)行駛工(gong)況下提供最(zui)佳助(zhu)(zhu)力(li)，減小由路面不(bu)平(ping)所引起(qi)(qi)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)的(de)(de)(de)(de)輸出轉(zhuan)矩通過傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)(de)(de)(de)作用(yong)而助(zhu)(zhu)力(li)向(xiang)(xiang)(xiang)系(xi)的(de)(de)(de)(de)擾(rao)動(dong)(dong)(dong)(dong)(dong)(dong)，改善汽(qi)車的(de)(de)(de)(de)轉(zhuan)向(xiang)(xiang)(xiang)特性，提高(gao)汽(qi)車的(de)(de)(de)(de)主動(dong)(dong)(dong)(dong)(dong)(dong)安全性。和液(ye)(ye)壓(ya)助(zhu)(zhu)力(li)相比(bi)沒有(you)液(ye)(ye)壓(ya)回路，調整(zheng)和檢測更容易，裝配(pei)自動(dong)(dong)(dong)(dong)(dong)(dong)化程(cheng)度更高(gao)，且可通過設置不(bu)同(tong)(tong)的(de)(de)(de)(de)程(cheng)序，快速(su)以(yi)及不(bu)同(tong)(tong)車型匹配(pei)，縮短(duan)生產和開發(fa)周期(qi)。

扭(niu)矩傳感器的作用(yong)是測量動態扭(niu)矩和靜態扭(niu)矩，其檢測穩定性(xing)、抗干(gan)擾(rao)性(xing)，以(yi)及(ji)精度都很好，每(mei)次使用(yong)不需要調整為零。
