扭矩傳感器簡介

在方向盤(pan)下(xia)邊的(de)方向桿上找到助力電機(ji)，電機(ji)上一(yi)(yi)(yi)般有(you)一(yi)(yi)(yi)個(ge)小(xiao)鐵蓋護(hu)著(zhu)的(de)、帶(dai)(dai)四根線（帶(dai)(dai)有(you)一(yi)(yi)(yi)個(ge)插(cha)頭）的(de)就(jiu)是轉向助力扭(niu)矩(ju)傳(chuan)感器，拆下(xia)小(xiao)鐵蓋就(jiu)能(neng)看(kan)到。

電(dian)(dian)動(dong)助(zhu)力轉(zhuan)向(xiang)(xiang)系(xi)統(tong)主(zhu)要由(you)扭(niu)(niu)矩(ju)(ju)傳感(gan)器，車速傳感(gan)器，電(dian)(dian)動(dong)機(ji)，減速機(ji)構與電(dian)(dian)子(zi)控(kong)制單(dan)(dan)(dan)元(yuan)等組成。該系(xi)統(tong)通過(guo)扭(niu)(niu)矩(ju)(ju)傳感(gan)器感(gan)知(zhi)駕(jia)駛員在(zai)轉(zhuan)向(xiang)(xiang)操作時方向(xiang)(xiang)盤產(chan)生(sheng)的扭(niu)(niu)矩(ju)(ju)力和轉(zhuan)向(xiang)(xiang)角度，就(jiu)會把(ba)操控(kong)信息(xi)轉(zhuan)換成數字信號(hao)輸入到(dao)控(kong)制單(dan)(dan)(dan)元(yuan)，再經過(guo)控(kong)制單(dan)(dan)(dan)元(yuan)對這些(xie)信號(hao)進行運算得到(dao)一(yi)個最(zui)(zui)佳的力矩(ju)(ju)最(zui)(zui)后(hou)控(kong)制驅使電(dian)(dian)動(dong)機(ji)工作。以上就(jiu)是整個電(dian)(dian)動(dong)助(zhu)力系(xi)統(tong)構成和工作的過(guo)程，不難看出扭(niu)(niu)矩(ju)(ju)傳感(gan)器在(zai)電(dian)(dian)動(dong)助(zhu)力系(xi)統(tong)中是最(zui)(zui)為重要的器件之一(yi)。

扭矩傳感器的作用

扭(niu)矩(ju)傳(chuan)感器在(zai)(zai)(zai)電(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)系(xi)統(tong)(tong)中的(de)(de)(de)作用(yong)電(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)系(xi)統(tong)(tong)可(ke)以稱之(zhi)為EPS，它(ta)就是一種(zhong)直接(jie)依靠電(dian)機提(ti)(ti)供輔助(zhu)(zhu)(zhu)(zhu)(zhu)扭(niu)矩(ju)的(de)(de)(de)動(dong)(dong)(dong)力(li)(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)系(xi)統(tong)(tong)。在(zai)(zai)(zai)整個系(xi)統(tong)(tong)中，扭(niu)矩(ju)傳(chuan)感器起到(dao)決定性(xing)作用(yong)。與傳(chuan)統(tong)(tong)的(de)(de)(de)液壓助(zhu)(zhu)(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)系(xi)統(tong)(tong)不(bu)(bu)同(tong)的(de)(de)(de)是電(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)系(xi)統(tong)(tong)具(ju)有性(xing)能應用(yong)上更大(da)的(de)(de)(de)優勢。它(ta)不(bu)(bu)光(guang)在(zai)(zai)(zai)需要轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)時才啟動(dong)(dong)(dong)電(dian)機產生(sheng)助(zhu)(zhu)(zhu)(zhu)(zhu)力(li)(li)，這(zhe)樣能大(da)大(da)的(de)(de)(de)減少發(fa)動(dong)(dong)(dong)機燃油消耗。電(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)(zhu)力(li)(li)能在(zai)(zai)(zai)各(ge)種(zhong)行駛工況下提(ti)(ti)供最佳(jia)助(zhu)(zhu)(zhu)(zhu)(zhu)力(li)(li)，減小由路面不(bu)(bu)平所引(yin)起電(dian)動(dong)(dong)(dong)機的(de)(de)(de)輸出轉(zhuan)(zhuan)(zhuan)矩(ju)通過(guo)傳(chuan)動(dong)(dong)(dong)裝(zhuang)置的(de)(de)(de)作用(yong)而助(zhu)(zhu)(zhu)(zhu)(zhu)力(li)(li)向(xiang)(xiang)系(xi)的(de)(de)(de)擾動(dong)(dong)(dong)，改善汽車(che)的(de)(de)(de)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)特(te)性(xing)，提(ti)(ti)高汽車(che)的(de)(de)(de)主動(dong)(dong)(dong)安全(quan)性(xing)。和(he)液壓助(zhu)(zhu)(zhu)(zhu)(zhu)力(li)(li)相(xiang)比沒有液壓回路，調整和(he)檢測更容(rong)易，裝(zhuang)配自動(dong)(dong)(dong)化(hua)程(cheng)度更高，且可(ke)通過(guo)設置不(bu)(bu)同(tong)的(de)(de)(de)程(cheng)序(xu)，快速(su)以及(ji)不(bu)(bu)同(tong)車(che)型匹配，縮短生(sheng)產和(he)開發(fa)周期。

扭矩(ju)傳感器的作用是測量動態(tai)扭矩(ju)和靜態(tai)扭矩(ju)，其(qi)檢(jian)測穩定性、抗干擾性，以及精度都很好，每次使用不(bu)需要調整(zheng)為零。
