扭矩傳感器簡介

在方向(xiang)盤下邊的(de)方向(xiang)桿上找(zhao)到助力電(dian)機，電(dian)機上一般有(you)一個小(xiao)鐵蓋護著(zhu)的(de)、帶四(si)根線（帶有(you)一個插頭(tou)）的(de)就是(shi)轉向(xiang)助力扭矩傳感(gan)器，拆下小(xiao)鐵蓋就能看到。

電(dian)動(dong)(dong)助(zhu)力轉向(xiang)系統(tong)主要(yao)由扭矩(ju)傳(chuan)感(gan)(gan)器(qi)，車(che)速傳(chuan)感(gan)(gan)器(qi)，電(dian)動(dong)(dong)機(ji)(ji)，減速機(ji)(ji)構(gou)(gou)與電(dian)子控(kong)(kong)制單元等組成(cheng)。該系統(tong)通過扭矩(ju)傳(chuan)感(gan)(gan)器(qi)感(gan)(gan)知駕(jia)駛員在(zai)轉向(xiang)操(cao)作(zuo)時方向(xiang)盤產生的扭矩(ju)力和(he)轉向(xiang)角度(du)，就(jiu)會把(ba)操(cao)控(kong)(kong)信(xin)息轉換成(cheng)數字信(xin)號輸入到控(kong)(kong)制單元，再經過控(kong)(kong)制單元對這些信(xin)號進行運算得到一個最(zui)佳的力矩(ju)最(zui)后控(kong)(kong)制驅使電(dian)動(dong)(dong)機(ji)(ji)工作(zuo)。以上(shang)就(jiu)是整個電(dian)動(dong)(dong)助(zhu)力系統(tong)構(gou)(gou)成(cheng)和(he)工作(zuo)的過程，不難看出扭矩(ju)傳(chuan)感(gan)(gan)器(qi)在(zai)電(dian)動(dong)(dong)助(zhu)力系統(tong)中是最(zui)為重要(yao)的器(qi)件之(zhi)一。

扭矩傳感器的作用

扭(niu)矩傳感器(qi)在(zai)電(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)力轉(zhuan)(zhuan)向系(xi)統中的(de)(de)作用電(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)力轉(zhuan)(zhuan)向系(xi)統可(ke)以稱之為(wei)EPS，它就是(shi)一種(zhong)(zhong)直接依靠(kao)電(dian)(dian)機提供(gong)輔助(zhu)(zhu)扭(niu)矩的(de)(de)動(dong)(dong)(dong)力轉(zhuan)(zhuan)向系(xi)統。在(zai)整(zheng)個系(xi)統中，扭(niu)矩傳感器(qi)起到決定性作用。與傳統的(de)(de)液(ye)壓助(zhu)(zhu)力轉(zhuan)(zhuan)向系(xi)統不(bu)同(tong)的(de)(de)是(shi)電(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)力轉(zhuan)(zhuan)向系(xi)統具(ju)有性能(neng)應用上更(geng)(geng)大的(de)(de)優勢。它不(bu)光在(zai)需要(yao)轉(zhuan)(zhuan)向時(shi)才啟動(dong)(dong)(dong)電(dian)(dian)機產生助(zhu)(zhu)力，這樣(yang)能(neng)大大的(de)(de)減(jian)(jian)少發動(dong)(dong)(dong)機燃油消耗。電(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)力能(neng)在(zai)各種(zhong)(zhong)行駛工況下提供(gong)最佳助(zhu)(zhu)力，減(jian)(jian)小由路(lu)面不(bu)平所引起電(dian)(dian)動(dong)(dong)(dong)機的(de)(de)輸出轉(zhuan)(zhuan)矩通(tong)過傳動(dong)(dong)(dong)裝(zhuang)置的(de)(de)作用而助(zhu)(zhu)力向系(xi)的(de)(de)擾(rao)動(dong)(dong)(dong)，改善汽(qi)車(che)的(de)(de)轉(zhuan)(zhuan)向特性，提高汽(qi)車(che)的(de)(de)主動(dong)(dong)(dong)安全性。和液(ye)壓助(zhu)(zhu)力相比(bi)沒(mei)有液(ye)壓回路(lu)，調整(zheng)和檢測(ce)更(geng)(geng)容易，裝(zhuang)配(pei)自動(dong)(dong)(dong)化程度更(geng)(geng)高，且可(ke)通(tong)過設置不(bu)同(tong)的(de)(de)程序(xu)，快速以及不(bu)同(tong)車(che)型匹(pi)配(pei)，縮短生產和開發周期。

扭(niu)矩傳(chuan)感器的作用是測量(liang)動態(tai)扭(niu)矩和靜態(tai)扭(niu)矩，其檢測穩定性(xing)、抗干擾(rao)性(xing)，以(yi)及精度(du)都(dou)很好，每(mei)次使用不需要(yao)調整為(wei)零。
