扭矩傳感器簡介

在方向盤(pan)下(xia)邊的(de)方向桿上找到助(zhu)力電機，電機上一(yi)(yi)般有一(yi)(yi)個小(xiao)鐵蓋護著的(de)、帶(dai)四根(gen)線（帶(dai)有一(yi)(yi)個插頭）的(de)就(jiu)是轉向助(zhu)力扭矩(ju)傳感器，拆(chai)下(xia)小(xiao)鐵蓋就(jiu)能看到。

電(dian)動(dong)助力轉(zhuan)向(xiang)系統(tong)主要由扭(niu)矩(ju)傳(chuan)(chuan)感(gan)器，車速傳(chuan)(chuan)感(gan)器，電(dian)動(dong)機(ji)，減速機(ji)構與電(dian)子控(kong)制單元(yuan)等組成。該(gai)系統(tong)通過扭(niu)矩(ju)傳(chuan)(chuan)感(gan)器感(gan)知駕駛員(yuan)在轉(zhuan)向(xiang)操(cao)作(zuo)時(shi)方向(xiang)盤產生的扭(niu)矩(ju)力和(he)轉(zhuan)向(xiang)角(jiao)度，就(jiu)會(hui)把操(cao)控(kong)信息轉(zhuan)換成數字(zi)信號輸(shu)入到控(kong)制單元(yuan)，再(zai)經過控(kong)制單元(yuan)對這(zhe)些信號進行運算得到一個(ge)最(zui)佳的力矩(ju)最(zui)后控(kong)制驅使電(dian)動(dong)機(ji)工(gong)(gong)作(zuo)。以上(shang)就(jiu)是整(zheng)個(ge)電(dian)動(dong)助力系統(tong)構成和(he)工(gong)(gong)作(zuo)的過程，不難看(kan)出(chu)扭(niu)矩(ju)傳(chuan)(chuan)感(gan)器在電(dian)動(dong)助力系統(tong)中是最(zui)為重要的器件之一。

扭矩傳感器的作用

扭(niu)矩(ju)傳感器在電(dian)動(dong)(dong)(dong)助(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)(zhuan)(zhuan)向(xiang)系統(tong)中的(de)(de)(de)(de)作(zuo)用電(dian)動(dong)(dong)(dong)助(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)(zhuan)(zhuan)向(xiang)系統(tong)可以(yi)(yi)稱之(zhi)為EPS，它就是一(yi)種(zhong)直接依靠電(dian)機(ji)提供(gong)輔助(zhu)(zhu)扭(niu)矩(ju)的(de)(de)(de)(de)動(dong)(dong)(dong)力(li)(li)轉(zhuan)(zhuan)(zhuan)(zhuan)向(xiang)系統(tong)。在整個系統(tong)中，扭(niu)矩(ju)傳感器起到決定(ding)性作(zuo)用。與傳統(tong)的(de)(de)(de)(de)液壓助(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)(zhuan)(zhuan)向(xiang)系統(tong)不同(tong)(tong)的(de)(de)(de)(de)是電(dian)動(dong)(dong)(dong)助(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)(zhuan)(zhuan)向(xiang)系統(tong)具有(you)性能應用上更大(da)的(de)(de)(de)(de)優勢(shi)。它不光在需要轉(zhuan)(zhuan)(zhuan)(zhuan)向(xiang)時(shi)才啟動(dong)(dong)(dong)電(dian)機(ji)產生助(zhu)(zhu)力(li)(li)，這樣能大(da)大(da)的(de)(de)(de)(de)減(jian)少(shao)發(fa)動(dong)(dong)(dong)機(ji)燃油消(xiao)耗。電(dian)動(dong)(dong)(dong)助(zhu)(zhu)力(li)(li)能在各種(zhong)行(xing)駛工況(kuang)下提供(gong)最佳(jia)助(zhu)(zhu)力(li)(li)，減(jian)小由路面不平所引起電(dian)動(dong)(dong)(dong)機(ji)的(de)(de)(de)(de)輸出轉(zhuan)(zhuan)(zhuan)(zhuan)矩(ju)通(tong)過(guo)傳動(dong)(dong)(dong)裝置(zhi)的(de)(de)(de)(de)作(zuo)用而(er)助(zhu)(zhu)力(li)(li)向(xiang)系的(de)(de)(de)(de)擾(rao)動(dong)(dong)(dong)，改(gai)善汽(qi)車的(de)(de)(de)(de)轉(zhuan)(zhuan)(zhuan)(zhuan)向(xiang)特性，提高汽(qi)車的(de)(de)(de)(de)主動(dong)(dong)(dong)安全性。和液壓助(zhu)(zhu)力(li)(li)相比沒有(you)液壓回(hui)路，調(diao)整和檢測更容易，裝配自動(dong)(dong)(dong)化(hua)程度更高，且可通(tong)過(guo)設置(zhi)不同(tong)(tong)的(de)(de)(de)(de)程序，快(kuai)速以(yi)(yi)及不同(tong)(tong)車型(xing)匹配，縮短生產和開發(fa)周期。

扭矩傳感器(qi)的作(zuo)用是測量動(dong)態扭矩和靜(jing)態扭矩，其檢測穩定性、抗干擾性，以及精(jing)度都很(hen)好，每次使(shi)用不需(xu)要調整為零。
