扭矩傳感器簡介

在方(fang)向盤(pan)下邊(bian)的方(fang)向桿上找到助(zhu)力電機，電機上一般有一個小(xiao)鐵(tie)蓋護著的、帶(dai)四(si)根線（帶(dai)有一個插頭）的就是轉向助(zhu)力扭(niu)矩傳(chuan)感(gan)器(qi)，拆下小(xiao)鐵(tie)蓋就能看到。

電(dian)動助(zhu)力轉(zhuan)向系(xi)統(tong)主要(yao)由(you)扭矩(ju)傳感(gan)器(qi)，車速傳感(gan)器(qi)，電(dian)動機(ji)，減速機(ji)構與電(dian)子控(kong)制單元等組(zu)成。該系(xi)統(tong)通過扭矩(ju)傳感(gan)器(qi)感(gan)知駕駛(shi)員在轉(zhuan)向操(cao)作時方向盤產生的扭矩(ju)力和(he)轉(zhuan)向角(jiao)度，就會把(ba)操(cao)控(kong)信息轉(zhuan)換成數字信號輸入到(dao)控(kong)制單元，再經(jing)過控(kong)制單元對這些信號進(jin)行運算得到(dao)一(yi)個最佳的力矩(ju)最后控(kong)制驅使(shi)電(dian)動機(ji)工作。以上就是整個電(dian)動助(zhu)力系(xi)統(tong)構成和(he)工作的過程，不難看出扭矩(ju)傳感(gan)器(qi)在電(dian)動助(zhu)力系(xi)統(tong)中是最為重要(yao)的器(qi)件之一(yi)。

扭矩傳感器的作用

扭(niu)矩(ju)(ju)傳感器(qi)在電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)向(xiang)系(xi)(xi)統(tong)中(zhong)的(de)作(zuo)用(yong)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)向(xiang)系(xi)(xi)統(tong)可以(yi)稱之為EPS，它(ta)就(jiu)是(shi)一種直接依(yi)靠電(dian)(dian)(dian)(dian)機提供輔助(zhu)(zhu)(zhu)扭(niu)矩(ju)(ju)的(de)動(dong)(dong)(dong)力(li)轉(zhuan)向(xiang)系(xi)(xi)統(tong)。在整(zheng)個系(xi)(xi)統(tong)中(zhong)，扭(niu)矩(ju)(ju)傳感器(qi)起到決定(ding)性(xing)作(zuo)用(yong)。與傳統(tong)的(de)液壓(ya)助(zhu)(zhu)(zhu)力(li)轉(zhuan)向(xiang)系(xi)(xi)統(tong)不同(tong)的(de)是(shi)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)向(xiang)系(xi)(xi)統(tong)具有(you)(you)性(xing)能應(ying)用(yong)上更大(da)(da)的(de)優勢。它(ta)不光在需(xu)要轉(zhuan)向(xiang)時才啟(qi)動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)機產生(sheng)助(zhu)(zhu)(zhu)力(li)，這樣能大(da)(da)大(da)(da)的(de)減少發動(dong)(dong)(dong)機燃油(you)消耗(hao)。電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)能在各種行駛工況(kuang)下提供最佳助(zhu)(zhu)(zhu)力(li)，減小由(you)路面不平所引起電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機的(de)輸出轉(zhuan)矩(ju)(ju)通過傳動(dong)(dong)(dong)裝置(zhi)的(de)作(zuo)用(yong)而助(zhu)(zhu)(zhu)力(li)向(xiang)系(xi)(xi)的(de)擾動(dong)(dong)(dong)，改(gai)善(shan)汽車的(de)轉(zhuan)向(xiang)特性(xing)，提高汽車的(de)主動(dong)(dong)(dong)安全性(xing)。和(he)(he)液壓(ya)助(zhu)(zhu)(zhu)力(li)相(xiang)比沒有(you)(you)液壓(ya)回(hui)路，調(diao)整(zheng)和(he)(he)檢測更容易，裝配自動(dong)(dong)(dong)化程度(du)更高，且可通過設置(zhi)不同(tong)的(de)程序，快速以(yi)及(ji)不同(tong)車型匹(pi)配，縮短生(sheng)產和(he)(he)開(kai)發周期(qi)。

扭矩(ju)傳感(gan)器(qi)的作用是測量動態扭矩(ju)和(he)靜態扭矩(ju)，其(qi)檢測穩定(ding)性、抗(kang)干擾(rao)性，以及(ji)精度(du)都(dou)很好，每次使用不(bu)需要調整為零。
