扭矩傳感器簡介

在方向盤(pan)下邊(bian)的(de)方向桿上(shang)找到助力電(dian)機，電(dian)機上(shang)一般有一個小鐵蓋護著的(de)、帶四根線（帶有一個插頭）的(de)就(jiu)是轉(zhuan)向助力扭矩(ju)傳感器，拆下小鐵蓋就(jiu)能(neng)看到。

電(dian)動助(zhu)力轉向(xiang)系統(tong)(tong)主要(yao)由扭(niu)矩傳感器(qi)，車速傳感器(qi)，電(dian)動機(ji)(ji)，減速機(ji)(ji)構(gou)與(yu)電(dian)子(zi)控(kong)制(zhi)單元(yuan)(yuan)(yuan)等組成。該系統(tong)(tong)通過扭(niu)矩傳感器(qi)感知駕駛(shi)員在(zai)轉向(xiang)操作時(shi)方向(xiang)盤產生的(de)扭(niu)矩力和轉向(xiang)角度，就會(hui)把操控(kong)信(xin)(xin)息轉換成數字信(xin)(xin)號輸(shu)入到控(kong)制(zhi)單元(yuan)(yuan)(yuan)，再(zai)經過控(kong)制(zhi)單元(yuan)(yuan)(yuan)對這(zhe)些信(xin)(xin)號進(jin)行運(yun)算(suan)得到一個(ge)最(zui)佳的(de)力矩最(zui)后(hou)控(kong)制(zhi)驅使電(dian)動機(ji)(ji)工作。以上(shang)就是整個(ge)電(dian)動助(zhu)力系統(tong)(tong)構(gou)成和工作的(de)過程，不難看出扭(niu)矩傳感器(qi)在(zai)電(dian)動助(zhu)力系統(tong)(tong)中是最(zui)為重要(yao)的(de)器(qi)件(jian)之一。

扭矩傳感器的作用

扭矩傳感(gan)器在電(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)力(li)(li)轉(zhuan)向(xiang)系(xi)統(tong)(tong)(tong)中的作用電(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)力(li)(li)轉(zhuan)向(xiang)系(xi)統(tong)(tong)(tong)可以稱之為EPS，它就(jiu)是一種直接依靠(kao)電(dian)(dian)機(ji)(ji)提(ti)供輔助(zhu)(zhu)扭矩的動(dong)(dong)(dong)力(li)(li)轉(zhuan)向(xiang)系(xi)統(tong)(tong)(tong)。在整個系(xi)統(tong)(tong)(tong)中，扭矩傳感(gan)器起到決定性作用。與傳統(tong)(tong)(tong)的液(ye)(ye)壓助(zhu)(zhu)力(li)(li)轉(zhuan)向(xiang)系(xi)統(tong)(tong)(tong)不(bu)同(tong)(tong)的是電(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)力(li)(li)轉(zhuan)向(xiang)系(xi)統(tong)(tong)(tong)具有性能(neng)應用上更大的優(you)勢。它不(bu)光在需要轉(zhuan)向(xiang)時才啟動(dong)(dong)(dong)電(dian)(dian)機(ji)(ji)產生助(zhu)(zhu)力(li)(li)，這樣能(neng)大大的減少(shao)發動(dong)(dong)(dong)機(ji)(ji)燃(ran)油消(xiao)耗。電(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)力(li)(li)能(neng)在各種行(xing)駛工況下(xia)提(ti)供最佳(jia)助(zhu)(zhu)力(li)(li)，減小由(you)路面(mian)不(bu)平(ping)所引起電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)的輸出轉(zhuan)矩通過傳動(dong)(dong)(dong)裝置(zhi)的作用而助(zhu)(zhu)力(li)(li)向(xiang)系(xi)的擾(rao)動(dong)(dong)(dong)，改善汽車(che)(che)的轉(zhuan)向(xiang)特(te)性，提(ti)高汽車(che)(che)的主動(dong)(dong)(dong)安(an)全(quan)性。和(he)(he)液(ye)(ye)壓助(zhu)(zhu)力(li)(li)相比沒有液(ye)(ye)壓回路，調(diao)整和(he)(he)檢測更容易，裝配(pei)(pei)自(zi)動(dong)(dong)(dong)化(hua)程度(du)更高，且(qie)可通過設置(zhi)不(bu)同(tong)(tong)的程序(xu)，快速以及(ji)不(bu)同(tong)(tong)車(che)(che)型匹配(pei)(pei)，縮短生產和(he)(he)開發周期。

扭(niu)(niu)矩(ju)傳感器的作用是測(ce)量(liang)動(dong)態(tai)扭(niu)(niu)矩(ju)和靜態(tai)扭(niu)(niu)矩(ju)，其檢測(ce)穩定性(xing)、抗干擾性(xing)，以及精(jing)度(du)都很好，每次使(shi)用不需要調(diao)整為零(ling)。
