扭矩傳感器簡介

在方向(xiang)(xiang)盤(pan)下邊(bian)的方向(xiang)(xiang)桿上找到(dao)助力電(dian)(dian)機，電(dian)(dian)機上一(yi)般有(you)一(yi)個小鐵蓋(gai)護著的、帶(dai)(dai)四根(gen)線(xian)（帶(dai)(dai)有(you)一(yi)個插(cha)頭）的就是轉向(xiang)(xiang)助力扭矩傳感器，拆下小鐵蓋(gai)就能看到(dao)。

電動(dong)助力轉向系(xi)統(tong)主(zhu)要由扭矩(ju)(ju)傳(chuan)(chuan)感器，車速(su)傳(chuan)(chuan)感器，電動(dong)機(ji)(ji)，減速(su)機(ji)(ji)構與電子控(kong)制單(dan)元等組成。該系(xi)統(tong)通過扭矩(ju)(ju)傳(chuan)(chuan)感器感知駕駛員在轉向操作時方向盤產生的扭矩(ju)(ju)力和轉向角度(du)，就(jiu)(jiu)會把(ba)操控(kong)信(xin)息轉換成數(shu)字信(xin)號輸入到(dao)控(kong)制單(dan)元，再經過控(kong)制單(dan)元對這些(xie)信(xin)號進行運(yun)算得(de)到(dao)一個最(zui)佳的力矩(ju)(ju)最(zui)后控(kong)制驅(qu)使電動(dong)機(ji)(ji)工作。以上(shang)就(jiu)(jiu)是(shi)整個電動(dong)助力系(xi)統(tong)構成和工作的過程，不難看出扭矩(ju)(ju)傳(chuan)(chuan)感器在電動(dong)助力系(xi)統(tong)中(zhong)是(shi)最(zui)為重要的器件之一。

扭矩傳感器的作用

扭矩(ju)傳感器(qi)在(zai)(zai)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向系統(tong)中(zhong)的(de)作(zuo)用電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向系統(tong)可以稱(cheng)之為(wei)EPS，它就是(shi)一(yi)種直(zhi)接(jie)依靠電(dian)(dian)(dian)機提供(gong)輔助(zhu)(zhu)(zhu)扭矩(ju)的(de)動(dong)(dong)(dong)(dong)力(li)轉(zhuan)(zhuan)(zhuan)向系統(tong)。在(zai)(zai)整(zheng)個系統(tong)中(zhong)，扭矩(ju)傳感器(qi)起(qi)到決定性作(zuo)用。與傳統(tong)的(de)液(ye)壓(ya)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向系統(tong)不同的(de)是(shi)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向系統(tong)具有(you)性能(neng)應用上(shang)更大(da)的(de)優勢(shi)。它不光(guang)在(zai)(zai)需要轉(zhuan)(zhuan)(zhuan)向時(shi)才啟動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)機產生(sheng)助(zhu)(zhu)(zhu)力(li)，這(zhe)樣能(neng)大(da)大(da)的(de)減(jian)少(shao)發動(dong)(dong)(dong)(dong)機燃油(you)消耗。電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)能(neng)在(zai)(zai)各種行(xing)駛工(gong)況下提供(gong)最(zui)佳助(zhu)(zhu)(zhu)力(li)，減(jian)小由路面不平所引起(qi)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機的(de)輸出(chu)轉(zhuan)(zhuan)(zhuan)矩(ju)通(tong)過傳動(dong)(dong)(dong)(dong)裝置(zhi)的(de)作(zuo)用而(er)助(zhu)(zhu)(zhu)力(li)向系的(de)擾動(dong)(dong)(dong)(dong)，改(gai)善汽車的(de)轉(zhuan)(zhuan)(zhuan)向特(te)性，提高汽車的(de)主(zhu)動(dong)(dong)(dong)(dong)安全性。和(he)液(ye)壓(ya)助(zhu)(zhu)(zhu)力(li)相比(bi)沒有(you)液(ye)壓(ya)回路，調(diao)整(zheng)和(he)檢(jian)測更容易，裝配自動(dong)(dong)(dong)(dong)化程度更高，且可通(tong)過設置(zhi)不同的(de)程序(xu)，快速以及不同車型匹配，縮短(duan)生(sheng)產和(he)開發周期。

扭(niu)矩(ju)傳感器的作用是測(ce)量(liang)動(dong)態扭(niu)矩(ju)和靜態扭(niu)矩(ju)，其檢(jian)測(ce)穩(wen)定性(xing)、抗干擾(rao)性(xing)，以(yi)及精度都很(hen)好，每次使(shi)用不需要調整為零。
