扭矩傳感器簡介

在(zai)方(fang)向(xiang)盤下邊的(de)方(fang)向(xiang)桿上找到(dao)助(zhu)力(li)電機，電機上一(yi)般(ban)有一(yi)個小(xiao)(xiao)鐵蓋護(hu)著的(de)、帶(dai)(dai)四根線（帶(dai)(dai)有一(yi)個插頭）的(de)就是轉向(xiang)助(zhu)力(li)扭(niu)矩傳(chuan)感器(qi)，拆下小(xiao)(xiao)鐵蓋就能看到(dao)。

電(dian)(dian)(dian)動助力轉向(xiang)(xiang)系統主要由扭(niu)矩(ju)傳感器(qi)，車(che)速傳感器(qi)，電(dian)(dian)(dian)動機，減速機構(gou)與電(dian)(dian)(dian)子控(kong)制(zhi)單元等組(zu)成(cheng)。該系統通過(guo)扭(niu)矩(ju)傳感器(qi)感知駕駛(shi)員在轉向(xiang)(xiang)操作時(shi)方向(xiang)(xiang)盤產(chan)生的(de)扭(niu)矩(ju)力和轉向(xiang)(xiang)角度，就會(hui)把(ba)操控(kong)信息(xi)轉換(huan)成(cheng)數字信號輸入到控(kong)制(zhi)單元，再經(jing)過(guo)控(kong)制(zhi)單元對(dui)這些信號進行運算得到一(yi)個最(zui)佳的(de)力矩(ju)最(zui)后控(kong)制(zhi)驅(qu)使電(dian)(dian)(dian)動機工(gong)作。以上就是整個電(dian)(dian)(dian)動助力系統構(gou)成(cheng)和工(gong)作的(de)過(guo)程(cheng)，不難(nan)看出(chu)扭(niu)矩(ju)傳感器(qi)在電(dian)(dian)(dian)動助力系統中是最(zui)為重要的(de)器(qi)件之(zhi)一(yi)。

扭矩傳感器的作用

扭矩(ju)傳感(gan)器(qi)在(zai)電(dian)(dian)動(dong)(dong)(dong)(dong)助(zhu)(zhu)力轉向(xiang)(xiang)系統中(zhong)的(de)作用電(dian)(dian)動(dong)(dong)(dong)(dong)助(zhu)(zhu)力轉向(xiang)(xiang)系統可以稱之(zhi)為EPS，它就是一(yi)種直接依靠電(dian)(dian)機(ji)提(ti)(ti)供(gong)輔(fu)助(zhu)(zhu)扭矩(ju)的(de)動(dong)(dong)(dong)(dong)力轉向(xiang)(xiang)系統。在(zai)整(zheng)個系統中(zhong)，扭矩(ju)傳感(gan)器(qi)起到決定性作用。與傳統的(de)液(ye)壓(ya)(ya)(ya)助(zhu)(zhu)力轉向(xiang)(xiang)系統不(bu)同(tong)(tong)的(de)是電(dian)(dian)動(dong)(dong)(dong)(dong)助(zhu)(zhu)力轉向(xiang)(xiang)系統具有(you)性能(neng)(neng)應用上更大(da)的(de)優勢。它不(bu)光在(zai)需要(yao)轉向(xiang)(xiang)時才啟動(dong)(dong)(dong)(dong)電(dian)(dian)機(ji)產生(sheng)助(zhu)(zhu)力，這樣能(neng)(neng)大(da)大(da)的(de)減(jian)少(shao)發動(dong)(dong)(dong)(dong)機(ji)燃油消耗。電(dian)(dian)動(dong)(dong)(dong)(dong)助(zhu)(zhu)力能(neng)(neng)在(zai)各種行駛工況(kuang)下(xia)提(ti)(ti)供(gong)最(zui)佳助(zhu)(zhu)力，減(jian)小(xiao)由路(lu)面(mian)不(bu)平所引起電(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)的(de)輸出轉矩(ju)通過傳動(dong)(dong)(dong)(dong)裝(zhuang)(zhuang)置(zhi)的(de)作用而(er)助(zhu)(zhu)力向(xiang)(xiang)系的(de)擾動(dong)(dong)(dong)(dong)，改善汽車的(de)轉向(xiang)(xiang)特性，提(ti)(ti)高汽車的(de)主(zhu)動(dong)(dong)(dong)(dong)安(an)全(quan)性。和液(ye)壓(ya)(ya)(ya)助(zhu)(zhu)力相比(bi)沒有(you)液(ye)壓(ya)(ya)(ya)回路(lu)，調整(zheng)和檢測更容易，裝(zhuang)(zhuang)配(pei)自(zi)動(dong)(dong)(dong)(dong)化(hua)程(cheng)度(du)更高，且(qie)可通過設置(zhi)不(bu)同(tong)(tong)的(de)程(cheng)序，快速以及不(bu)同(tong)(tong)車型匹配(pei)，縮短生(sheng)產和開發周期。

扭矩(ju)傳(chuan)感器的作用是測量動態扭矩(ju)和靜態扭矩(ju)，其(qi)檢測穩定性、抗干擾性，以及精度都很好(hao)，每次使用不(bu)需要(yao)調整為零。
