扭矩傳感器簡介

在方(fang)向盤下邊的(de)方(fang)向桿上找到助力電機，電機上一(yi)般有一(yi)個小鐵蓋護著的(de)、帶(dai)四根線(xian)（帶(dai)有一(yi)個插頭(tou)）的(de)就是轉向助力扭(niu)矩傳(chuan)感器，拆(chai)下小鐵蓋就能看(kan)到。

電(dian)動(dong)(dong)助力(li)轉(zhuan)向(xiang)系統主要由扭矩(ju)(ju)傳(chuan)感(gan)器(qi)，車(che)速(su)(su)傳(chuan)感(gan)器(qi)，電(dian)動(dong)(dong)機，減速(su)(su)機構與電(dian)子控(kong)制單元等組成。該系統通過(guo)扭矩(ju)(ju)傳(chuan)感(gan)器(qi)感(gan)知(zhi)駕駛(shi)員在轉(zhuan)向(xiang)操作(zuo)時方向(xiang)盤產(chan)生的(de)扭矩(ju)(ju)力(li)和(he)轉(zhuan)向(xiang)角度，就會把操控(kong)信息(xi)轉(zhuan)換(huan)成數字(zi)信號(hao)輸入到控(kong)制單元，再經過(guo)控(kong)制單元對(dui)這些信號(hao)進行運算得到一個(ge)最佳的(de)力(li)矩(ju)(ju)最后控(kong)制驅使電(dian)動(dong)(dong)機工作(zuo)。以上就是整個(ge)電(dian)動(dong)(dong)助力(li)系統構成和(he)工作(zuo)的(de)過(guo)程，不難看(kan)出扭矩(ju)(ju)傳(chuan)感(gan)器(qi)在電(dian)動(dong)(dong)助力(li)系統中是最為(wei)重要的(de)器(qi)件之一。

扭矩傳感器的作用

扭(niu)矩傳(chuan)感器在電動(dong)(dong)助(zhu)(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)向(xiang)系(xi)(xi)(xi)統(tong)(tong)(tong)中(zhong)的(de)(de)(de)作(zuo)用(yong)電動(dong)(dong)助(zhu)(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)向(xiang)系(xi)(xi)(xi)統(tong)(tong)(tong)可以稱之為EPS，它就是(shi)一種直接依靠電機提(ti)供(gong)輔助(zhu)(zhu)(zhu)(zhu)扭(niu)矩的(de)(de)(de)動(dong)(dong)力(li)轉(zhuan)(zhuan)向(xiang)系(xi)(xi)(xi)統(tong)(tong)(tong)。在整(zheng)(zheng)個(ge)系(xi)(xi)(xi)統(tong)(tong)(tong)中(zhong)，扭(niu)矩傳(chuan)感器起到(dao)決定(ding)性作(zuo)用(yong)。與傳(chuan)統(tong)(tong)(tong)的(de)(de)(de)液(ye)(ye)壓助(zhu)(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)向(xiang)系(xi)(xi)(xi)統(tong)(tong)(tong)不同(tong)的(de)(de)(de)是(shi)電動(dong)(dong)助(zhu)(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)向(xiang)系(xi)(xi)(xi)統(tong)(tong)(tong)具有性能(neng)應(ying)用(yong)上更(geng)大(da)的(de)(de)(de)優(you)勢。它不光(guang)在需要轉(zhuan)(zhuan)向(xiang)時才啟動(dong)(dong)電機產(chan)生助(zhu)(zhu)(zhu)(zhu)力(li)，這(zhe)樣(yang)能(neng)大(da)大(da)的(de)(de)(de)減(jian)少發動(dong)(dong)機燃油消耗。電動(dong)(dong)助(zhu)(zhu)(zhu)(zhu)力(li)能(neng)在各種行駛工況下提(ti)供(gong)最佳(jia)助(zhu)(zhu)(zhu)(zhu)力(li)，減(jian)小由路面(mian)不平(ping)所引起電動(dong)(dong)機的(de)(de)(de)輸(shu)出轉(zhuan)(zhuan)矩通過(guo)傳(chuan)動(dong)(dong)裝置的(de)(de)(de)作(zuo)用(yong)而助(zhu)(zhu)(zhu)(zhu)力(li)向(xiang)系(xi)(xi)(xi)的(de)(de)(de)擾(rao)動(dong)(dong)，改善汽車的(de)(de)(de)轉(zhuan)(zhuan)向(xiang)特性，提(ti)高汽車的(de)(de)(de)主動(dong)(dong)安全(quan)性。和(he)液(ye)(ye)壓助(zhu)(zhu)(zhu)(zhu)力(li)相比(bi)沒有液(ye)(ye)壓回路，調整(zheng)(zheng)和(he)檢測更(geng)容(rong)易，裝配自動(dong)(dong)化程(cheng)(cheng)度更(geng)高，且可通過(guo)設(she)置不同(tong)的(de)(de)(de)程(cheng)(cheng)序，快速以及不同(tong)車型匹配，縮短生產(chan)和(he)開(kai)發周期(qi)。

扭矩傳感器的(de)作用是測量動態(tai)扭矩和靜態(tai)扭矩，其檢測穩定性、抗干擾性，以(yi)及精度(du)都很好，每次使(shi)用不需要調(diao)整(zheng)為零。
