扭矩傳感器簡介

在方向盤下邊的(de)方向桿上找到(dao)助力(li)電機，電機上一般有一個(ge)小(xiao)鐵蓋(gai)護(hu)著的(de)、帶(dai)四根線（帶(dai)有一個(ge)插頭）的(de)就(jiu)是轉(zhuan)向助力(li)扭矩傳感器，拆下小(xiao)鐵蓋(gai)就(jiu)能看到(dao)。

電(dian)(dian)動助(zhu)力(li)(li)轉向(xiang)系(xi)統(tong)(tong)主(zhu)要(yao)由扭(niu)矩(ju)傳(chuan)感(gan)器，車(che)速傳(chuan)感(gan)器，電(dian)(dian)動機(ji)，減(jian)速機(ji)構與(yu)電(dian)(dian)子控(kong)(kong)(kong)(kong)制(zhi)單(dan)(dan)元等組成(cheng)。該(gai)系(xi)統(tong)(tong)通過(guo)扭(niu)矩(ju)傳(chuan)感(gan)器感(gan)知駕(jia)駛員在(zai)轉向(xiang)操作(zuo)時(shi)方(fang)向(xiang)盤產生的(de)(de)扭(niu)矩(ju)力(li)(li)和轉向(xiang)角(jiao)度，就會把操控(kong)(kong)(kong)(kong)信(xin)息轉換(huan)成(cheng)數字信(xin)號輸入到控(kong)(kong)(kong)(kong)制(zhi)單(dan)(dan)元，再(zai)經過(guo)控(kong)(kong)(kong)(kong)制(zhi)單(dan)(dan)元對這些信(xin)號進行運算得到一個(ge)最佳的(de)(de)力(li)(li)矩(ju)最后控(kong)(kong)(kong)(kong)制(zhi)驅(qu)使電(dian)(dian)動機(ji)工作(zuo)。以上就是整個(ge)電(dian)(dian)動助(zhu)力(li)(li)系(xi)統(tong)(tong)構成(cheng)和工作(zuo)的(de)(de)過(guo)程，不難看出扭(niu)矩(ju)傳(chuan)感(gan)器在(zai)電(dian)(dian)動助(zhu)力(li)(li)系(xi)統(tong)(tong)中是最為重要(yao)的(de)(de)器件之一。

扭矩傳感器的作用

扭(niu)矩傳感器在(zai)(zai)電(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)系統中的(de)(de)作用電(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)系統可以(yi)稱(cheng)之為EPS，它(ta)就是一種直接依(yi)靠電(dian)(dian)(dian)機(ji)提供(gong)輔助(zhu)(zhu)(zhu)扭(niu)矩的(de)(de)動(dong)(dong)(dong)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)系統。在(zai)(zai)整個系統中，扭(niu)矩傳感器起到決定性(xing)作用。與傳統的(de)(de)液(ye)壓助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)系統不同(tong)的(de)(de)是電(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)系統具(ju)有性(xing)能(neng)應用上(shang)更大的(de)(de)優(you)勢。它(ta)不光在(zai)(zai)需要轉(zhuan)(zhuan)(zhuan)向(xiang)時才(cai)啟動(dong)(dong)(dong)電(dian)(dian)(dian)機(ji)產生助(zhu)(zhu)(zhu)力(li)，這樣能(neng)大大的(de)(de)減(jian)少發(fa)動(dong)(dong)(dong)機(ji)燃(ran)油消耗。電(dian)(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)能(neng)在(zai)(zai)各種行駛工況下(xia)提供(gong)最佳助(zhu)(zhu)(zhu)力(li)，減(jian)小(xiao)由(you)路面(mian)不平所引(yin)起電(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)的(de)(de)輸(shu)出轉(zhuan)(zhuan)(zhuan)矩通(tong)過(guo)傳動(dong)(dong)(dong)裝置的(de)(de)作用而助(zhu)(zhu)(zhu)力(li)向(xiang)系的(de)(de)擾動(dong)(dong)(dong)，改善汽(qi)(qi)車的(de)(de)轉(zhuan)(zhuan)(zhuan)向(xiang)特性(xing)，提高汽(qi)(qi)車的(de)(de)主動(dong)(dong)(dong)安全(quan)性(xing)。和液(ye)壓助(zhu)(zhu)(zhu)力(li)相比沒有液(ye)壓回路，調(diao)整和檢(jian)測(ce)更容易(yi)，裝配自動(dong)(dong)(dong)化程度更高，且可通(tong)過(guo)設置不同(tong)的(de)(de)程序，快(kuai)速以(yi)及不同(tong)車型匹配，縮短生產和開發(fa)周期(qi)。

扭矩(ju)(ju)傳感器(qi)的作用是測量動態(tai)扭矩(ju)(ju)和靜(jing)態(tai)扭矩(ju)(ju)，其檢測穩(wen)定性(xing)、抗干擾性(xing)，以(yi)及精度都很好，每次(ci)使用不需要(yao)調整為(wei)零。
