扭矩傳感器簡介

在方向(xiang)盤下邊的方向(xiang)桿(gan)上(shang)找到助力(li)電(dian)(dian)機，電(dian)(dian)機上(shang)一般有(you)一個小鐵蓋(gai)護著的、帶(dai)四根(gen)線（帶(dai)有(you)一個插頭）的就(jiu)是轉向(xiang)助力(li)扭矩(ju)傳感器，拆下小鐵蓋(gai)就(jiu)能看到。

電(dian)動(dong)助(zhu)力(li)轉(zhuan)向系統(tong)(tong)主要(yao)(yao)由扭(niu)矩傳(chuan)感(gan)器，車速(su)傳(chuan)感(gan)器，電(dian)動(dong)機，減速(su)機構與電(dian)子(zi)控(kong)制(zhi)(zhi)(zhi)單(dan)元等組成。該系統(tong)(tong)通過扭(niu)矩傳(chuan)感(gan)器感(gan)知(zhi)駕駛員在轉(zhuan)向操作(zuo)時方向盤(pan)產生的(de)扭(niu)矩力(li)和轉(zhuan)向角(jiao)度，就(jiu)會把操控(kong)信息轉(zhuan)換成數(shu)字信號輸入到控(kong)制(zhi)(zhi)(zhi)單(dan)元，再經過控(kong)制(zhi)(zhi)(zhi)單(dan)元對這些信號進(jin)行運算得到一個最(zui)佳的(de)力(li)矩最(zui)后控(kong)制(zhi)(zhi)(zhi)驅使電(dian)動(dong)機工作(zuo)。以上就(jiu)是(shi)整個電(dian)動(dong)助(zhu)力(li)系統(tong)(tong)構成和工作(zuo)的(de)過程(cheng)，不(bu)難看出扭(niu)矩傳(chuan)感(gan)器在電(dian)動(dong)助(zhu)力(li)系統(tong)(tong)中是(shi)最(zui)為重要(yao)(yao)的(de)器件之一。

扭矩傳感器的作用

扭(niu)矩傳感器在(zai)電(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)力轉(zhuan)向(xiang)(xiang)系統(tong)(tong)中的(de)(de)(de)(de)作(zuo)用電(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)力轉(zhuan)向(xiang)(xiang)系統(tong)(tong)可以稱之為EPS，它就是一種(zhong)直接依靠電(dian)(dian)(dian)機提(ti)供輔(fu)助(zhu)(zhu)(zhu)(zhu)扭(niu)矩的(de)(de)(de)(de)動(dong)(dong)(dong)力轉(zhuan)向(xiang)(xiang)系統(tong)(tong)。在(zai)整個系統(tong)(tong)中，扭(niu)矩傳感器起到決定性(xing)作(zuo)用。與傳統(tong)(tong)的(de)(de)(de)(de)液(ye)壓(ya)助(zhu)(zhu)(zhu)(zhu)力轉(zhuan)向(xiang)(xiang)系統(tong)(tong)不(bu)同的(de)(de)(de)(de)是電(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)力轉(zhuan)向(xiang)(xiang)系統(tong)(tong)具有(you)性(xing)能應用上(shang)更大(da)的(de)(de)(de)(de)優勢。它不(bu)光在(zai)需(xu)要轉(zhuan)向(xiang)(xiang)時(shi)才啟動(dong)(dong)(dong)電(dian)(dian)(dian)機產生(sheng)(sheng)助(zhu)(zhu)(zhu)(zhu)力，這樣能大(da)大(da)的(de)(de)(de)(de)減少發動(dong)(dong)(dong)機燃油消耗。電(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)(zhu)力能在(zai)各種(zhong)行駛工況下提(ti)供最佳(jia)助(zhu)(zhu)(zhu)(zhu)力，減小由路面(mian)不(bu)平所引起電(dian)(dian)(dian)動(dong)(dong)(dong)機的(de)(de)(de)(de)輸出轉(zhuan)矩通(tong)過(guo)傳動(dong)(dong)(dong)裝置的(de)(de)(de)(de)作(zuo)用而助(zhu)(zhu)(zhu)(zhu)力向(xiang)(xiang)系的(de)(de)(de)(de)擾動(dong)(dong)(dong)，改善(shan)汽(qi)車(che)的(de)(de)(de)(de)轉(zhuan)向(xiang)(xiang)特性(xing)，提(ti)高汽(qi)車(che)的(de)(de)(de)(de)主動(dong)(dong)(dong)安全性(xing)。和液(ye)壓(ya)助(zhu)(zhu)(zhu)(zhu)力相比沒有(you)液(ye)壓(ya)回(hui)路，調整和檢測(ce)更容易，裝配自動(dong)(dong)(dong)化(hua)程度更高，且可通(tong)過(guo)設置不(bu)同的(de)(de)(de)(de)程序，快速以及不(bu)同車(che)型(xing)匹配，縮(suo)短生(sheng)(sheng)產和開(kai)發周期。

扭(niu)矩傳感器的作(zuo)用是測(ce)量動態(tai)扭(niu)矩和靜態(tai)扭(niu)矩，其檢測(ce)穩定性、抗干擾性，以及精度都很好，每(mei)次(ci)使(shi)用不(bu)需要(yao)調整為零。
