扭矩傳感器簡介

在方向(xiang)盤(pan)下邊的方向(xiang)桿上(shang)(shang)找到(dao)(dao)助力電(dian)機，電(dian)機上(shang)(shang)一(yi)般(ban)有一(yi)個(ge)小(xiao)鐵蓋護著的、帶(dai)四根(gen)線（帶(dai)有一(yi)個(ge)插頭）的就(jiu)是轉(zhuan)向(xiang)助力扭矩傳感器，拆(chai)下小(xiao)鐵蓋就(jiu)能看到(dao)(dao)。

電(dian)動(dong)助力轉(zhuan)向系(xi)統主要(yao)由扭(niu)矩(ju)傳(chuan)感(gan)器(qi)(qi)，車速傳(chuan)感(gan)器(qi)(qi)，電(dian)動(dong)機，減(jian)速機構(gou)與電(dian)子控制單(dan)元(yuan)(yuan)等組成。該系(xi)統通過扭(niu)矩(ju)傳(chuan)感(gan)器(qi)(qi)感(gan)知駕駛(shi)員在(zai)轉(zhuan)向操作時方(fang)向盤產生(sheng)的(de)扭(niu)矩(ju)力和轉(zhuan)向角度，就會(hui)把操控信息轉(zhuan)換成數字信號(hao)輸入到(dao)控制單(dan)元(yuan)(yuan)，再經過控制單(dan)元(yuan)(yuan)對這些(xie)信號(hao)進行(xing)運算得(de)到(dao)一個最(zui)(zui)佳(jia)的(de)力矩(ju)最(zui)(zui)后控制驅使電(dian)動(dong)機工作。以上就是(shi)整個電(dian)動(dong)助力系(xi)統構(gou)成和工作的(de)過程(cheng)，不(bu)難看出(chu)扭(niu)矩(ju)傳(chuan)感(gan)器(qi)(qi)在(zai)電(dian)動(dong)助力系(xi)統中是(shi)最(zui)(zui)為重要(yao)的(de)器(qi)(qi)件(jian)之一。

扭矩傳感器的作用

扭矩傳(chuan)感器(qi)在電(dian)(dian)動(dong)(dong)助(zhu)(zhu)力(li)(li)(li)(li)轉(zhuan)向(xiang)系(xi)統(tong)(tong)(tong)(tong)中的(de)作用(yong)電(dian)(dian)動(dong)(dong)助(zhu)(zhu)力(li)(li)(li)(li)轉(zhuan)向(xiang)系(xi)統(tong)(tong)(tong)(tong)可以稱之為EPS，它(ta)就(jiu)是一種(zhong)直接(jie)依靠(kao)電(dian)(dian)機提(ti)供輔助(zhu)(zhu)扭矩的(de)動(dong)(dong)力(li)(li)(li)(li)轉(zhuan)向(xiang)系(xi)統(tong)(tong)(tong)(tong)。在整(zheng)個系(xi)統(tong)(tong)(tong)(tong)中，扭矩傳(chuan)感器(qi)起到決定性(xing)(xing)作用(yong)。與傳(chuan)統(tong)(tong)(tong)(tong)的(de)液(ye)壓(ya)助(zhu)(zhu)力(li)(li)(li)(li)轉(zhuan)向(xiang)系(xi)統(tong)(tong)(tong)(tong)不(bu)同(tong)(tong)的(de)是電(dian)(dian)動(dong)(dong)助(zhu)(zhu)力(li)(li)(li)(li)轉(zhuan)向(xiang)系(xi)統(tong)(tong)(tong)(tong)具(ju)有性(xing)(xing)能應用(yong)上更(geng)大的(de)優勢。它(ta)不(bu)光在需(xu)要轉(zhuan)向(xiang)時(shi)才(cai)啟動(dong)(dong)電(dian)(dian)機產生(sheng)助(zhu)(zhu)力(li)(li)(li)(li)，這樣能大大的(de)減少發動(dong)(dong)機燃(ran)油消(xiao)耗(hao)。電(dian)(dian)動(dong)(dong)助(zhu)(zhu)力(li)(li)(li)(li)能在各種(zhong)行駛工(gong)況下(xia)提(ti)供最佳助(zhu)(zhu)力(li)(li)(li)(li)，減小由路面不(bu)平所引起電(dian)(dian)動(dong)(dong)機的(de)輸出轉(zhuan)矩通過傳(chuan)動(dong)(dong)裝置的(de)作用(yong)而助(zhu)(zhu)力(li)(li)(li)(li)向(xiang)系(xi)的(de)擾動(dong)(dong)，改善汽車(che)的(de)轉(zhuan)向(xiang)特性(xing)(xing)，提(ti)高汽車(che)的(de)主動(dong)(dong)安全性(xing)(xing)。和液(ye)壓(ya)助(zhu)(zhu)力(li)(li)(li)(li)相比沒有液(ye)壓(ya)回路，調(diao)整(zheng)和檢(jian)測(ce)更(geng)容易，裝配自動(dong)(dong)化(hua)程度(du)更(geng)高，且可通過設置不(bu)同(tong)(tong)的(de)程序，快(kuai)速以及不(bu)同(tong)(tong)車(che)型匹配，縮短生(sheng)產和開發周(zhou)期。

扭矩(ju)(ju)傳感器的作用是測量動(dong)態(tai)扭矩(ju)(ju)和(he)靜(jing)態(tai)扭矩(ju)(ju)，其檢測穩定(ding)性(xing)、抗(kang)干擾性(xing)，以及精度都很(hen)好，每(mei)次使(shi)用不(bu)需要調整為零(ling)。
