扭矩傳感器簡介

在(zai)方(fang)向(xiang)盤下(xia)邊的(de)(de)方(fang)向(xiang)桿上(shang)找到(dao)助力電機，電機上(shang)一(yi)般有(you)(you)一(yi)個(ge)小鐵蓋護著(zhu)的(de)(de)、帶四根線（帶有(you)(you)一(yi)個(ge)插頭）的(de)(de)就是轉向(xiang)助力扭(niu)矩傳(chuan)感器，拆下(xia)小鐵蓋就能看到(dao)。

電(dian)(dian)(dian)動(dong)助(zhu)力(li)轉(zhuan)向系(xi)統(tong)(tong)主(zhu)要由扭矩(ju)(ju)傳(chuan)(chuan)感器，車速傳(chuan)(chuan)感器，電(dian)(dian)(dian)動(dong)機(ji)，減速機(ji)構(gou)(gou)與(yu)電(dian)(dian)(dian)子控(kong)(kong)制(zhi)單元等組成(cheng)。該(gai)系(xi)統(tong)(tong)通過扭矩(ju)(ju)傳(chuan)(chuan)感器感知(zhi)駕(jia)駛(shi)員在轉(zhuan)向操(cao)作時方向盤產生的扭矩(ju)(ju)力(li)和轉(zhuan)向角(jiao)度，就(jiu)會把操(cao)控(kong)(kong)信(xin)(xin)息轉(zhuan)換(huan)成(cheng)數字(zi)信(xin)(xin)號(hao)輸入到(dao)控(kong)(kong)制(zhi)單元，再經過控(kong)(kong)制(zhi)單元對(dui)這(zhe)些信(xin)(xin)號(hao)進行運算(suan)得到(dao)一個最(zui)佳的力(li)矩(ju)(ju)最(zui)后(hou)控(kong)(kong)制(zhi)驅使電(dian)(dian)(dian)動(dong)機(ji)工(gong)(gong)作。以上就(jiu)是(shi)整(zheng)個電(dian)(dian)(dian)動(dong)助(zhu)力(li)系(xi)統(tong)(tong)構(gou)(gou)成(cheng)和工(gong)(gong)作的過程，不難看出(chu)扭矩(ju)(ju)傳(chuan)(chuan)感器在電(dian)(dian)(dian)動(dong)助(zhu)力(li)系(xi)統(tong)(tong)中是(shi)最(zui)為(wei)重要的器件之(zhi)一。

扭矩傳感器的作用

扭(niu)矩傳(chuan)感器在電(dian)(dian)動(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)(xiang)(xiang)系(xi)(xi)統(tong)中的作用(yong)電(dian)(dian)動(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)(xiang)(xiang)系(xi)(xi)統(tong)可(ke)以(yi)稱之為EPS，它(ta)就是一種(zhong)(zhong)直(zhi)接(jie)依靠電(dian)(dian)機提供輔(fu)助(zhu)(zhu)(zhu)扭(niu)矩的動(dong)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)(xiang)(xiang)系(xi)(xi)統(tong)。在整(zheng)個系(xi)(xi)統(tong)中，扭(niu)矩傳(chuan)感器起到決(jue)定性(xing)作用(yong)。與傳(chuan)統(tong)的液壓(ya)(ya)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)(xiang)(xiang)系(xi)(xi)統(tong)不同的是電(dian)(dian)動(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)(xiang)(xiang)系(xi)(xi)統(tong)具有性(xing)能(neng)應用(yong)上更大的優勢。它(ta)不光在需要(yao)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)(xiang)(xiang)時才啟動(dong)電(dian)(dian)機產生助(zhu)(zhu)(zhu)力(li)，這(zhe)樣(yang)能(neng)大大的減少(shao)發動(dong)機燃油(you)消耗。電(dian)(dian)動(dong)助(zhu)(zhu)(zhu)力(li)能(neng)在各種(zhong)(zhong)行駛工況下(xia)提供最佳助(zhu)(zhu)(zhu)力(li)，減小(xiao)由路(lu)面不平所引起電(dian)(dian)動(dong)機的輸出轉(zhuan)(zhuan)(zhuan)矩通(tong)過傳(chuan)動(dong)裝(zhuang)置的作用(yong)而助(zhu)(zhu)(zhu)力(li)向(xiang)(xiang)(xiang)(xiang)系(xi)(xi)的擾動(dong)，改善汽(qi)(qi)車的轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)(xiang)(xiang)特性(xing)，提高(gao)汽(qi)(qi)車的主(zhu)動(dong)安全性(xing)。和(he)(he)液壓(ya)(ya)助(zhu)(zhu)(zhu)力(li)相比沒有液壓(ya)(ya)回路(lu)，調整(zheng)和(he)(he)檢測更容易，裝(zhuang)配自動(dong)化程度更高(gao)，且(qie)可(ke)通(tong)過設置不同的程序，快(kuai)速(su)以(yi)及不同車型匹配，縮(suo)短生產和(he)(he)開發周期。

扭(niu)矩傳感(gan)器的作(zuo)用是測量動態扭(niu)矩和(he)靜(jing)態扭(niu)矩，其檢測穩定性、抗干(gan)擾(rao)性，以及(ji)精度都很好，每次使用不(bu)需要調整為零。
