扭矩傳感器簡介

在方向盤(pan)下邊的(de)方向桿上(shang)找到助(zhu)力電機，電機上(shang)一(yi)(yi)般有一(yi)(yi)個小(xiao)鐵(tie)(tie)蓋護著的(de)、帶四(si)根線（帶有一(yi)(yi)個插頭(tou)）的(de)就是轉向助(zhu)力扭(niu)矩傳感器(qi)，拆下小(xiao)鐵(tie)(tie)蓋就能看到。

電動(dong)助力(li)轉(zhuan)向系(xi)(xi)統(tong)(tong)主要由(you)扭矩(ju)傳(chuan)(chuan)感(gan)(gan)器，車速傳(chuan)(chuan)感(gan)(gan)器，電動(dong)機，減速機構與(yu)電子控制(zhi)單元等(deng)組成(cheng)。該系(xi)(xi)統(tong)(tong)通過(guo)扭矩(ju)傳(chuan)(chuan)感(gan)(gan)器感(gan)(gan)知駕駛員在轉(zhuan)向操作(zuo)時方向盤產生的扭矩(ju)力(li)和轉(zhuan)向角度，就會(hui)把操控信(xin)息轉(zhuan)換成(cheng)數字信(xin)號輸入到控制(zhi)單元，再經過(guo)控制(zhi)單元對這(zhe)些(xie)信(xin)號進行運算得到一個最佳(jia)的力(li)矩(ju)最后控制(zhi)驅使電動(dong)機工(gong)作(zuo)。以上就是整個電動(dong)助力(li)系(xi)(xi)統(tong)(tong)構成(cheng)和工(gong)作(zuo)的過(guo)程，不難看出扭矩(ju)傳(chuan)(chuan)感(gan)(gan)器在電動(dong)助力(li)系(xi)(xi)統(tong)(tong)中是最為重要的器件之一。

扭矩傳感器的作用

扭(niu)矩(ju)傳(chuan)(chuan)感器在(zai)(zai)電(dian)(dian)(dian)(dian)動(dong)助(zhu)力(li)(li)轉(zhuan)(zhuan)向(xiang)系(xi)統(tong)(tong)中的(de)(de)作(zuo)用(yong)電(dian)(dian)(dian)(dian)動(dong)助(zhu)力(li)(li)轉(zhuan)(zhuan)向(xiang)系(xi)統(tong)(tong)可(ke)以稱之為EPS，它就是一(yi)種直(zhi)接依靠電(dian)(dian)(dian)(dian)機提供(gong)輔助(zhu)扭(niu)矩(ju)的(de)(de)動(dong)力(li)(li)轉(zhuan)(zhuan)向(xiang)系(xi)統(tong)(tong)。在(zai)(zai)整(zheng)個系(xi)統(tong)(tong)中，扭(niu)矩(ju)傳(chuan)(chuan)感器起到(dao)決定性(xing)作(zuo)用(yong)。與傳(chuan)(chuan)統(tong)(tong)的(de)(de)液壓助(zhu)力(li)(li)轉(zhuan)(zhuan)向(xiang)系(xi)統(tong)(tong)不(bu)同(tong)的(de)(de)是電(dian)(dian)(dian)(dian)動(dong)助(zhu)力(li)(li)轉(zhuan)(zhuan)向(xiang)系(xi)統(tong)(tong)具有(you)性(xing)能(neng)應用(yong)上(shang)更(geng)大(da)的(de)(de)優勢。它不(bu)光在(zai)(zai)需要轉(zhuan)(zhuan)向(xiang)時才啟動(dong)電(dian)(dian)(dian)(dian)機產(chan)生(sheng)助(zhu)力(li)(li)，這(zhe)樣能(neng)大(da)大(da)的(de)(de)減少發(fa)動(dong)機燃油消耗(hao)。電(dian)(dian)(dian)(dian)動(dong)助(zhu)力(li)(li)能(neng)在(zai)(zai)各種行駛工況下(xia)提供(gong)最佳(jia)助(zhu)力(li)(li)，減小由路面不(bu)平所引起電(dian)(dian)(dian)(dian)動(dong)機的(de)(de)輸出轉(zhuan)(zhuan)矩(ju)通(tong)過傳(chuan)(chuan)動(dong)裝置(zhi)(zhi)的(de)(de)作(zuo)用(yong)而助(zhu)力(li)(li)向(xiang)系(xi)的(de)(de)擾動(dong)，改善汽車的(de)(de)轉(zhuan)(zhuan)向(xiang)特性(xing)，提高汽車的(de)(de)主動(dong)安全性(xing)。和(he)液壓助(zhu)力(li)(li)相比(bi)沒有(you)液壓回路，調(diao)整(zheng)和(he)檢測(ce)更(geng)容易，裝配自動(dong)化程度(du)更(geng)高，且可(ke)通(tong)過設置(zhi)(zhi)不(bu)同(tong)的(de)(de)程序，快速(su)以及不(bu)同(tong)車型(xing)匹配，縮短生(sheng)產(chan)和(he)開發(fa)周期。

扭矩(ju)(ju)傳感器的作用是測(ce)量(liang)動態扭矩(ju)(ju)和靜態扭矩(ju)(ju)，其檢(jian)測(ce)穩(wen)定性、抗(kang)干擾性，以及精度都很好，每次(ci)使用不需要調整為零。
