扭矩傳感器簡介

在方向盤(pan)下邊(bian)的方向桿上找到助力電(dian)機(ji)，電(dian)機(ji)上一般有一個(ge)小(xiao)(xiao)鐵(tie)蓋護著的、帶(dai)四根線（帶(dai)有一個(ge)插頭）的就(jiu)是轉向助力扭矩(ju)傳感器，拆下小(xiao)(xiao)鐵(tie)蓋就(jiu)能看(kan)到。

電(dian)動助力(li)轉向(xiang)系(xi)統(tong)主要(yao)由扭矩傳感器，車速傳感器，電(dian)動機(ji)(ji)，減速機(ji)(ji)構與電(dian)子控(kong)制單元等組(zu)成。該系(xi)統(tong)通過扭矩傳感器感知駕(jia)駛員在轉向(xiang)操作(zuo)時方向(xiang)盤(pan)產生的(de)扭矩力(li)和(he)(he)轉向(xiang)角度，就(jiu)(jiu)會把操控(kong)信(xin)息(xi)轉換成數字信(xin)號輸入到(dao)控(kong)制單元，再經過控(kong)制單元對這些信(xin)號進行運算得到(dao)一個最佳的(de)力(li)矩最后(hou)控(kong)制驅使電(dian)動機(ji)(ji)工(gong)作(zuo)。以上就(jiu)(jiu)是整個電(dian)動助力(li)系(xi)統(tong)構成和(he)(he)工(gong)作(zuo)的(de)過程，不難看出扭矩傳感器在電(dian)動助力(li)系(xi)統(tong)中是最為重要(yao)的(de)器件之一。

扭矩傳感器的作用

扭(niu)矩傳感(gan)器在(zai)電(dian)動(dong)(dong)(dong)助力(li)轉(zhuan)(zhuan)向(xiang)系(xi)統(tong)(tong)中的(de)(de)(de)作(zuo)(zuo)用(yong)電(dian)動(dong)(dong)(dong)助力(li)轉(zhuan)(zhuan)向(xiang)系(xi)統(tong)(tong)可以稱之(zhi)為(wei)EPS，它(ta)就是(shi)(shi)一種直接依(yi)靠(kao)電(dian)機提(ti)供輔助扭(niu)矩的(de)(de)(de)動(dong)(dong)(dong)力(li)轉(zhuan)(zhuan)向(xiang)系(xi)統(tong)(tong)。在(zai)整個系(xi)統(tong)(tong)中，扭(niu)矩傳感(gan)器起(qi)(qi)到決定性作(zuo)(zuo)用(yong)。與傳統(tong)(tong)的(de)(de)(de)液(ye)壓(ya)(ya)助力(li)轉(zhuan)(zhuan)向(xiang)系(xi)統(tong)(tong)不(bu)(bu)同(tong)(tong)的(de)(de)(de)是(shi)(shi)電(dian)動(dong)(dong)(dong)助力(li)轉(zhuan)(zhuan)向(xiang)系(xi)統(tong)(tong)具有(you)性能(neng)應(ying)用(yong)上更(geng)大(da)的(de)(de)(de)優勢(shi)。它(ta)不(bu)(bu)光在(zai)需要轉(zhuan)(zhuan)向(xiang)時才啟(qi)動(dong)(dong)(dong)電(dian)機產(chan)生助力(li)，這(zhe)樣能(neng)大(da)大(da)的(de)(de)(de)減少發(fa)動(dong)(dong)(dong)機燃油消耗。電(dian)動(dong)(dong)(dong)助力(li)能(neng)在(zai)各種行駛工況下提(ti)供最佳助力(li)，減小由(you)路面不(bu)(bu)平所引起(qi)(qi)電(dian)動(dong)(dong)(dong)機的(de)(de)(de)輸出(chu)轉(zhuan)(zhuan)矩通過傳動(dong)(dong)(dong)裝置(zhi)的(de)(de)(de)作(zuo)(zuo)用(yong)而助力(li)向(xiang)系(xi)的(de)(de)(de)擾(rao)動(dong)(dong)(dong)，改善汽(qi)車的(de)(de)(de)轉(zhuan)(zhuan)向(xiang)特性，提(ti)高(gao)(gao)汽(qi)車的(de)(de)(de)主動(dong)(dong)(dong)安全性。和(he)液(ye)壓(ya)(ya)助力(li)相比沒有(you)液(ye)壓(ya)(ya)回路，調整和(he)檢測更(geng)容易(yi)，裝配(pei)(pei)自動(dong)(dong)(dong)化程度更(geng)高(gao)(gao)，且可通過設置(zhi)不(bu)(bu)同(tong)(tong)的(de)(de)(de)程序，快速以及(ji)不(bu)(bu)同(tong)(tong)車型匹(pi)配(pei)(pei)，縮短生產(chan)和(he)開發(fa)周(zhou)期。

扭矩(ju)(ju)傳(chuan)感器的作用(yong)是測(ce)量動態扭矩(ju)(ju)和靜態扭矩(ju)(ju)，其檢測(ce)穩定性、抗干擾(rao)性，以及精度都很好，每(mei)次(ci)使用(yong)不需要調整為零。
