扭矩傳感器簡介

在(zai)方向盤下(xia)邊(bian)的(de)方向桿上找到助力電機(ji)，電機(ji)上一(yi)般有一(yi)個(ge)小鐵蓋護著的(de)、帶(dai)(dai)四(si)根線(xian)（帶(dai)(dai)有一(yi)個(ge)插頭）的(de)就是轉(zhuan)向助力扭(niu)矩傳感器，拆(chai)下(xia)小鐵蓋就能看到。

電(dian)動(dong)助(zhu)力(li)轉(zhuan)向(xiang)系(xi)統主(zhu)要由扭(niu)矩(ju)(ju)傳(chuan)感(gan)器，車(che)速(su)傳(chuan)感(gan)器，電(dian)動(dong)機(ji)，減速(su)機(ji)構與(yu)電(dian)子控(kong)制(zhi)(zhi)(zhi)單(dan)元(yuan)等組(zu)成(cheng)。該系(xi)統通過(guo)扭(niu)矩(ju)(ju)傳(chuan)感(gan)器感(gan)知駕駛(shi)員(yuan)在(zai)轉(zhuan)向(xiang)操作(zuo)時方向(xiang)盤產生(sheng)的(de)扭(niu)矩(ju)(ju)力(li)和轉(zhuan)向(xiang)角度，就(jiu)會(hui)把操控(kong)信(xin)(xin)(xin)息轉(zhuan)換成(cheng)數字(zi)信(xin)(xin)(xin)號(hao)輸入到(dao)控(kong)制(zhi)(zhi)(zhi)單(dan)元(yuan)，再經過(guo)控(kong)制(zhi)(zhi)(zhi)單(dan)元(yuan)對這些信(xin)(xin)(xin)號(hao)進行(xing)運(yun)算得到(dao)一個最(zui)佳的(de)力(li)矩(ju)(ju)最(zui)后控(kong)制(zhi)(zhi)(zhi)驅使電(dian)動(dong)機(ji)工作(zuo)。以上就(jiu)是(shi)整(zheng)個電(dian)動(dong)助(zhu)力(li)系(xi)統構成(cheng)和工作(zuo)的(de)過(guo)程，不難看出扭(niu)矩(ju)(ju)傳(chuan)感(gan)器在(zai)電(dian)動(dong)助(zhu)力(li)系(xi)統中是(shi)最(zui)為重要的(de)器件之一。

扭矩傳感器的作用

扭矩(ju)傳感器在電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)助力轉(zhuan)向系(xi)(xi)統中(zhong)的作用(yong)(yong)(yong)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)助力轉(zhuan)向系(xi)(xi)統可(ke)以稱之為EPS，它就是一種直接(jie)依(yi)靠(kao)電(dian)(dian)(dian)機(ji)提(ti)(ti)供(gong)輔(fu)助扭矩(ju)的動(dong)(dong)(dong)(dong)(dong)力轉(zhuan)向系(xi)(xi)統。在整個系(xi)(xi)統中(zhong)，扭矩(ju)傳感器起到(dao)決定性作用(yong)(yong)(yong)。與傳統的液壓(ya)助力轉(zhuan)向系(xi)(xi)統不同(tong)的是電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)助力轉(zhuan)向系(xi)(xi)統具有(you)性能(neng)應用(yong)(yong)(yong)上(shang)更(geng)大(da)的優勢。它不光在需要轉(zhuan)向時才啟動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)機(ji)產生助力，這樣能(neng)大(da)大(da)的減少(shao)發動(dong)(dong)(dong)(dong)(dong)機(ji)燃油消耗。電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)助力能(neng)在各種行駛工況下提(ti)(ti)供(gong)最(zui)佳助力，減小(xiao)由路(lu)面不平所(suo)引(yin)起電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)的輸出轉(zhuan)矩(ju)通過(guo)傳動(dong)(dong)(dong)(dong)(dong)裝置的作用(yong)(yong)(yong)而助力向系(xi)(xi)的擾動(dong)(dong)(dong)(dong)(dong)，改善汽車(che)的轉(zhuan)向特性，提(ti)(ti)高汽車(che)的主(zhu)動(dong)(dong)(dong)(dong)(dong)安全性。和液壓(ya)助力相比沒(mei)有(you)液壓(ya)回(hui)路(lu)，調整和檢測(ce)更(geng)容易，裝配(pei)自動(dong)(dong)(dong)(dong)(dong)化程度更(geng)高，且可(ke)通過(guo)設(she)置不同(tong)的程序，快速以及不同(tong)車(che)型匹配(pei)，縮(suo)短(duan)生產和開發周期。

扭矩(ju)(ju)傳(chuan)感器的作用(yong)是測量動態扭矩(ju)(ju)和靜態扭矩(ju)(ju)，其(qi)檢測穩定性、抗(kang)干擾性，以及精度(du)都很好，每次使用(yong)不需要(yao)調整為零。
