扭矩傳感器簡介

在方(fang)向(xiang)盤下邊的方(fang)向(xiang)桿上(shang)找到助力電機，電機上(shang)一般有一個(ge)小(xiao)鐵(tie)蓋(gai)護著的、帶(dai)四根(gen)線(xian)（帶(dai)有一個(ge)插頭）的就是(shi)轉向(xiang)助力扭矩傳感器，拆下小(xiao)鐵(tie)蓋(gai)就能看到。

電(dian)(dian)動(dong)(dong)助(zhu)力(li)(li)(li)轉(zhuan)向系統(tong)主要由(you)扭矩傳感(gan)器(qi)，車速傳感(gan)器(qi)，電(dian)(dian)動(dong)(dong)機，減速機構與(yu)電(dian)(dian)子控(kong)制(zhi)(zhi)單元等組成(cheng)。該系統(tong)通(tong)過(guo)扭矩傳感(gan)器(qi)感(gan)知駕駛員(yuan)在(zai)轉(zhuan)向操作時方向盤產生的扭矩力(li)(li)(li)和轉(zhuan)向角度，就(jiu)會把操控(kong)信(xin)息(xi)轉(zhuan)換(huan)成(cheng)數字信(xin)號輸入到控(kong)制(zhi)(zhi)單元，再經過(guo)控(kong)制(zhi)(zhi)單元對這些(xie)信(xin)號進行運算(suan)得到一個最(zui)佳的力(li)(li)(li)矩最(zui)后控(kong)制(zhi)(zhi)驅使電(dian)(dian)動(dong)(dong)機工(gong)作。以上就(jiu)是整個電(dian)(dian)動(dong)(dong)助(zhu)力(li)(li)(li)系統(tong)構成(cheng)和工(gong)作的過(guo)程，不(bu)難看(kan)出扭矩傳感(gan)器(qi)在(zai)電(dian)(dian)動(dong)(dong)助(zhu)力(li)(li)(li)系統(tong)中是最(zui)為(wei)重要的器(qi)件之一。

扭矩傳感器的作用

扭(niu)矩(ju)傳感器在電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)(zhu)力轉(zhuan)(zhuan)(zhuan)(zhuan)向(xiang)系(xi)統中的(de)(de)作用(yong)(yong)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)(zhu)力轉(zhuan)(zhuan)(zhuan)(zhuan)向(xiang)系(xi)統可以稱之為EPS，它(ta)就是一種(zhong)直接(jie)依靠電(dian)(dian)(dian)(dian)機(ji)(ji)提供(gong)輔助(zhu)(zhu)(zhu)(zhu)(zhu)扭(niu)矩(ju)的(de)(de)動(dong)(dong)(dong)力轉(zhuan)(zhuan)(zhuan)(zhuan)向(xiang)系(xi)統。在整個系(xi)統中，扭(niu)矩(ju)傳感器起到決定性作用(yong)(yong)。與傳統的(de)(de)液壓(ya)(ya)助(zhu)(zhu)(zhu)(zhu)(zhu)力轉(zhuan)(zhuan)(zhuan)(zhuan)向(xiang)系(xi)統不(bu)同的(de)(de)是電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)(zhu)力轉(zhuan)(zhuan)(zhuan)(zhuan)向(xiang)系(xi)統具(ju)有性能應用(yong)(yong)上更(geng)大的(de)(de)優勢。它(ta)不(bu)光在需要轉(zhuan)(zhuan)(zhuan)(zhuan)向(xiang)時才啟動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)機(ji)(ji)產生(sheng)助(zhu)(zhu)(zhu)(zhu)(zhu)力，這樣(yang)能大大的(de)(de)減(jian)少發動(dong)(dong)(dong)機(ji)(ji)燃油消耗(hao)。電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)(zhu)力能在各種(zhong)行(xing)駛工況下提供(gong)最佳助(zhu)(zhu)(zhu)(zhu)(zhu)力，減(jian)小由路(lu)(lu)面不(bu)平所(suo)引起電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)的(de)(de)輸(shu)出轉(zhuan)(zhuan)(zhuan)(zhuan)矩(ju)通(tong)過傳動(dong)(dong)(dong)裝置的(de)(de)作用(yong)(yong)而助(zhu)(zhu)(zhu)(zhu)(zhu)力向(xiang)系(xi)的(de)(de)擾動(dong)(dong)(dong)，改善汽(qi)車的(de)(de)轉(zhuan)(zhuan)(zhuan)(zhuan)向(xiang)特性，提高(gao)汽(qi)車的(de)(de)主動(dong)(dong)(dong)安全性。和液壓(ya)(ya)助(zhu)(zhu)(zhu)(zhu)(zhu)力相比沒有液壓(ya)(ya)回路(lu)(lu)，調整和檢測更(geng)容易，裝配(pei)自動(dong)(dong)(dong)化程度(du)更(geng)高(gao)，且可通(tong)過設(she)置不(bu)同的(de)(de)程序，快速(su)以及不(bu)同車型(xing)匹配(pei)，縮短生(sheng)產和開發周期(qi)。

扭(niu)矩(ju)傳感器(qi)的作用是測(ce)量動態(tai)(tai)扭(niu)矩(ju)和靜態(tai)(tai)扭(niu)矩(ju)，其檢測(ce)穩定性、抗干擾(rao)性，以及精度都(dou)很好，每次使用不需要調整為零。
