扭矩傳感器簡介

在方向(xiang)盤(pan)下(xia)邊(bian)的(de)方向(xiang)桿(gan)上找到(dao)(dao)助力電機(ji)，電機(ji)上一(yi)般有一(yi)個小(xiao)鐵蓋護著的(de)、帶四根線（帶有一(yi)個插(cha)頭）的(de)就是轉(zhuan)向(xiang)助力扭矩傳感器，拆下(xia)小(xiao)鐵蓋就能看到(dao)(dao)。

電(dian)動(dong)助(zhu)力轉(zhuan)向(xiang)(xiang)系(xi)統(tong)主要(yao)由扭(niu)矩(ju)傳(chuan)感(gan)器(qi)(qi)(qi)，車速傳(chuan)感(gan)器(qi)(qi)(qi)，電(dian)動(dong)機，減速機構(gou)與電(dian)子(zi)控制單(dan)元等組成(cheng)。該系(xi)統(tong)通過(guo)扭(niu)矩(ju)傳(chuan)感(gan)器(qi)(qi)(qi)感(gan)知駕駛員(yuan)在轉(zhuan)向(xiang)(xiang)操作(zuo)(zuo)時方向(xiang)(xiang)盤產生的扭(niu)矩(ju)力和轉(zhuan)向(xiang)(xiang)角度(du)，就會把操控信(xin)息轉(zhuan)換成(cheng)數字信(xin)號輸入到控制單(dan)元，再經過(guo)控制單(dan)元對這些信(xin)號進行運算得到一個最(zui)佳(jia)的力矩(ju)最(zui)后控制驅使電(dian)動(dong)機工作(zuo)(zuo)。以上就是整個電(dian)動(dong)助(zhu)力系(xi)統(tong)構(gou)成(cheng)和工作(zuo)(zuo)的過(guo)程，不難看出扭(niu)矩(ju)傳(chuan)感(gan)器(qi)(qi)(qi)在電(dian)動(dong)助(zhu)力系(xi)統(tong)中是最(zui)為重要(yao)的器(qi)(qi)(qi)件之一。

扭矩傳感器的作用

扭矩(ju)傳感器在電(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)向(xiang)(xiang)系統(tong)中的(de)作用(yong)(yong)(yong)電(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)向(xiang)(xiang)系統(tong)可(ke)以(yi)稱之為EPS，它就是(shi)一種直接依靠電(dian)機(ji)(ji)提(ti)(ti)供(gong)輔助(zhu)(zhu)(zhu)(zhu)扭矩(ju)的(de)動(dong)(dong)(dong)力(li)(li)轉(zhuan)(zhuan)向(xiang)(xiang)系統(tong)。在整(zheng)個系統(tong)中，扭矩(ju)傳感器起(qi)到決定性作用(yong)(yong)(yong)。與傳統(tong)的(de)液(ye)(ye)壓(ya)助(zhu)(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)向(xiang)(xiang)系統(tong)不(bu)同(tong)的(de)是(shi)電(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)向(xiang)(xiang)系統(tong)具有性能(neng)應(ying)用(yong)(yong)(yong)上更(geng)大(da)的(de)優勢。它不(bu)光在需要轉(zhuan)(zhuan)向(xiang)(xiang)時才啟動(dong)(dong)(dong)電(dian)機(ji)(ji)產生助(zhu)(zhu)(zhu)(zhu)力(li)(li)，這樣能(neng)大(da)大(da)的(de)減少(shao)發動(dong)(dong)(dong)機(ji)(ji)燃油消耗。電(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)力(li)(li)能(neng)在各(ge)種行駛工況下提(ti)(ti)供(gong)最佳助(zhu)(zhu)(zhu)(zhu)力(li)(li)，減小由路面不(bu)平所引起(qi)電(dian)動(dong)(dong)(dong)機(ji)(ji)的(de)輸出轉(zhuan)(zhuan)矩(ju)通過(guo)傳動(dong)(dong)(dong)裝置的(de)作用(yong)(yong)(yong)而助(zhu)(zhu)(zhu)(zhu)力(li)(li)向(xiang)(xiang)系的(de)擾動(dong)(dong)(dong)，改(gai)善汽車的(de)轉(zhuan)(zhuan)向(xiang)(xiang)特性，提(ti)(ti)高汽車的(de)主動(dong)(dong)(dong)安全(quan)性。和液(ye)(ye)壓(ya)助(zhu)(zhu)(zhu)(zhu)力(li)(li)相比沒有液(ye)(ye)壓(ya)回(hui)路，調整(zheng)和檢(jian)測(ce)更(geng)容(rong)易，裝配自動(dong)(dong)(dong)化程度更(geng)高，且可(ke)通過(guo)設置不(bu)同(tong)的(de)程序，快速以(yi)及不(bu)同(tong)車型匹配，縮短生產和開發周期。

扭(niu)(niu)矩傳感器的作用(yong)是(shi)測(ce)量(liang)動態(tai)扭(niu)(niu)矩和靜態(tai)扭(niu)(niu)矩，其(qi)檢(jian)測(ce)穩定性、抗干擾(rao)性，以及精度(du)都很好，每次使(shi)用(yong)不需要調整(zheng)為零(ling)。
