扭矩傳感器簡介

在方(fang)向(xiang)盤下邊的(de)(de)方(fang)向(xiang)桿上找(zhao)到(dao)助力(li)電機，電機上一般(ban)有一個小(xiao)鐵蓋(gai)護著的(de)(de)、帶四根線（帶有一個插頭）的(de)(de)就是轉向(xiang)助力(li)扭矩傳感器(qi)，拆下小(xiao)鐵蓋(gai)就能看(kan)到(dao)。

電(dian)(dian)(dian)動助(zhu)力(li)轉向系(xi)統(tong)主要(yao)由扭(niu)矩傳(chuan)(chuan)感(gan)器(qi)，車速(su)傳(chuan)(chuan)感(gan)器(qi)，電(dian)(dian)(dian)動機(ji)(ji)，減速(su)機(ji)(ji)構(gou)與電(dian)(dian)(dian)子(zi)控(kong)制(zhi)(zhi)(zhi)單元(yuan)等組成(cheng)(cheng)。該(gai)系(xi)統(tong)通過扭(niu)矩傳(chuan)(chuan)感(gan)器(qi)感(gan)知(zhi)駕駛員在(zai)轉向操(cao)作時方(fang)向盤產生的扭(niu)矩力(li)和轉向角度(du)，就會把(ba)操(cao)控(kong)信息轉換成(cheng)(cheng)數字信號輸(shu)入到(dao)控(kong)制(zhi)(zhi)(zhi)單元(yuan)，再(zai)經過控(kong)制(zhi)(zhi)(zhi)單元(yuan)對這些信號進行運算得到(dao)一個(ge)最佳的力(li)矩最后(hou)控(kong)制(zhi)(zhi)(zhi)驅使(shi)電(dian)(dian)(dian)動機(ji)(ji)工作。以上(shang)就是(shi)整(zheng)個(ge)電(dian)(dian)(dian)動助(zhu)力(li)系(xi)統(tong)構(gou)成(cheng)(cheng)和工作的過程，不難看出扭(niu)矩傳(chuan)(chuan)感(gan)器(qi)在(zai)電(dian)(dian)(dian)動助(zhu)力(li)系(xi)統(tong)中(zhong)是(shi)最為(wei)重要(yao)的器(qi)件之一。

扭矩傳感器的作用

扭(niu)矩(ju)傳(chuan)感(gan)器(qi)在電(dian)動(dong)(dong)助(zhu)(zhu)力(li)(li)(li)轉向系(xi)統(tong)(tong)(tong)中(zhong)的(de)(de)(de)作用(yong)電(dian)動(dong)(dong)助(zhu)(zhu)力(li)(li)(li)轉向系(xi)統(tong)(tong)(tong)可(ke)以稱之為EPS，它就是(shi)一種直接(jie)依靠電(dian)機提供輔助(zhu)(zhu)扭(niu)矩(ju)的(de)(de)(de)動(dong)(dong)力(li)(li)(li)轉向系(xi)統(tong)(tong)(tong)。在整(zheng)(zheng)個(ge)系(xi)統(tong)(tong)(tong)中(zhong)，扭(niu)矩(ju)傳(chuan)感(gan)器(qi)起到(dao)決定性作用(yong)。與傳(chuan)統(tong)(tong)(tong)的(de)(de)(de)液(ye)(ye)壓(ya)助(zhu)(zhu)力(li)(li)(li)轉向系(xi)統(tong)(tong)(tong)不同(tong)的(de)(de)(de)是(shi)電(dian)動(dong)(dong)助(zhu)(zhu)力(li)(li)(li)轉向系(xi)統(tong)(tong)(tong)具有性能應用(yong)上更大的(de)(de)(de)優勢。它不光(guang)在需要(yao)轉向時才啟動(dong)(dong)電(dian)機產生(sheng)助(zhu)(zhu)力(li)(li)(li)，這樣能大大的(de)(de)(de)減少發動(dong)(dong)機燃(ran)油(you)消耗。電(dian)動(dong)(dong)助(zhu)(zhu)力(li)(li)(li)能在各種行駛工(gong)況下提供最(zui)佳助(zhu)(zhu)力(li)(li)(li)，減小由路面不平(ping)所(suo)引起電(dian)動(dong)(dong)機的(de)(de)(de)輸出轉矩(ju)通過(guo)傳(chuan)動(dong)(dong)裝(zhuang)置(zhi)的(de)(de)(de)作用(yong)而助(zhu)(zhu)力(li)(li)(li)向系(xi)的(de)(de)(de)擾動(dong)(dong)，改善汽(qi)車(che)的(de)(de)(de)轉向特性，提高(gao)汽(qi)車(che)的(de)(de)(de)主動(dong)(dong)安全性。和(he)液(ye)(ye)壓(ya)助(zhu)(zhu)力(li)(li)(li)相比沒有液(ye)(ye)壓(ya)回路，調整(zheng)(zheng)和(he)檢(jian)測更容(rong)易，裝(zhuang)配自動(dong)(dong)化(hua)程(cheng)度更高(gao)，且可(ke)通過(guo)設(she)置(zhi)不同(tong)的(de)(de)(de)程(cheng)序，快速以及不同(tong)車(che)型(xing)匹配，縮短(duan)生(sheng)產和(he)開發周期。

扭(niu)矩傳感器的作用(yong)是測量動態(tai)扭(niu)矩和靜態(tai)扭(niu)矩，其檢測穩定性、抗(kang)干擾性，以(yi)及精度(du)都很好，每次使用(yong)不(bu)需要調整為零。
