扭矩傳感器簡介

在(zai)方向(xiang)盤下邊(bian)的(de)(de)方向(xiang)桿上找到助(zhu)力電(dian)(dian)機(ji)，電(dian)(dian)機(ji)上一般有一個小鐵蓋護著的(de)(de)、帶(dai)四根線（帶(dai)有一個插頭）的(de)(de)就(jiu)(jiu)是轉向(xiang)助(zhu)力扭矩傳感(gan)器，拆下小鐵蓋就(jiu)(jiu)能看到。

電(dian)(dian)(dian)動(dong)助力轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)系統(tong)主要由扭矩(ju)傳感器(qi)，車速(su)傳感器(qi)，電(dian)(dian)(dian)動(dong)機，減速(su)機構與(yu)電(dian)(dian)(dian)子控(kong)(kong)制單元等組成。該系統(tong)通過扭矩(ju)傳感器(qi)感知駕駛(shi)員在(zai)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)操作(zuo)時方(fang)向(xiang)(xiang)盤產(chan)生的扭矩(ju)力和轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)角度，就會把(ba)操控(kong)(kong)信(xin)(xin)息轉(zhuan)(zhuan)(zhuan)換(huan)成數字信(xin)(xin)號輸(shu)入到控(kong)(kong)制單元，再(zai)經過控(kong)(kong)制單元對(dui)這些信(xin)(xin)號進行運算得到一個(ge)最(zui)佳的力矩(ju)最(zui)后控(kong)(kong)制驅(qu)使電(dian)(dian)(dian)動(dong)機工作(zuo)。以上就是(shi)整個(ge)電(dian)(dian)(dian)動(dong)助力系統(tong)構成和工作(zuo)的過程(cheng)，不難看出扭矩(ju)傳感器(qi)在(zai)電(dian)(dian)(dian)動(dong)助力系統(tong)中是(shi)最(zui)為重(zhong)要的器(qi)件之一。

扭矩傳感器的作用

扭矩(ju)(ju)傳(chuan)感器在(zai)電(dian)(dian)(dian)動(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)(xiang)(xiang)系(xi)統(tong)(tong)中(zhong)的(de)(de)(de)作用(yong)電(dian)(dian)(dian)動(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)(xiang)(xiang)系(xi)統(tong)(tong)可以(yi)稱之為(wei)EPS，它就是(shi)一種直接依靠電(dian)(dian)(dian)機(ji)提供輔(fu)助(zhu)(zhu)(zhu)扭矩(ju)(ju)的(de)(de)(de)動(dong)(dong)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)(xiang)(xiang)系(xi)統(tong)(tong)。在(zai)整個系(xi)統(tong)(tong)中(zhong)，扭矩(ju)(ju)傳(chuan)感器起到決(jue)定性作用(yong)。與傳(chuan)統(tong)(tong)的(de)(de)(de)液壓(ya)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)(xiang)(xiang)系(xi)統(tong)(tong)不(bu)(bu)同的(de)(de)(de)是(shi)電(dian)(dian)(dian)動(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)(xiang)(xiang)系(xi)統(tong)(tong)具有性能應(ying)用(yong)上(shang)更大(da)的(de)(de)(de)優勢。它不(bu)(bu)光(guang)在(zai)需要轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)(xiang)(xiang)時才(cai)啟(qi)動(dong)(dong)電(dian)(dian)(dian)機(ji)產(chan)生助(zhu)(zhu)(zhu)力(li)，這(zhe)樣能大(da)大(da)的(de)(de)(de)減少發(fa)動(dong)(dong)機(ji)燃油消耗。電(dian)(dian)(dian)動(dong)(dong)助(zhu)(zhu)(zhu)力(li)能在(zai)各種行駛工況下提供最佳(jia)助(zhu)(zhu)(zhu)力(li)，減小由路(lu)面不(bu)(bu)平所引起電(dian)(dian)(dian)動(dong)(dong)機(ji)的(de)(de)(de)輸出轉(zhuan)(zhuan)(zhuan)矩(ju)(ju)通(tong)過傳(chuan)動(dong)(dong)裝置的(de)(de)(de)作用(yong)而助(zhu)(zhu)(zhu)力(li)向(xiang)(xiang)(xiang)(xiang)系(xi)的(de)(de)(de)擾動(dong)(dong)，改善汽車的(de)(de)(de)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)(xiang)(xiang)特性，提高汽車的(de)(de)(de)主(zhu)動(dong)(dong)安全(quan)性。和液壓(ya)助(zhu)(zhu)(zhu)力(li)相比沒(mei)有液壓(ya)回路(lu)，調整和檢測(ce)更容(rong)易，裝配自動(dong)(dong)化程度(du)更高，且(qie)可通(tong)過設(she)置不(bu)(bu)同的(de)(de)(de)程序(xu)，快速以(yi)及不(bu)(bu)同車型匹配，縮短生產(chan)和開發(fa)周(zhou)期(qi)。

扭(niu)(niu)矩(ju)(ju)傳感(gan)器的作用是測量(liang)動態扭(niu)(niu)矩(ju)(ju)和靜(jing)態扭(niu)(niu)矩(ju)(ju)，其檢(jian)測穩定性、抗干擾性，以(yi)及精度都很好，每(mei)次使用不需要調整(zheng)為(wei)零(ling)。

奧迪A3(進口)簡介

運動(dong)(dong)與(yu)動(dong)(dong)態(tai)，高(gao)(gao)(gao)超的(de)技(ji)術和高(gao)(gao)(gao)質量的(de)訴求：從第一次驅動(dong)(dong)這(zhe)款車，奧迪A3駕駛者就將它(ta)所有(you)特性珍(zhen)藏。由于(yu)它(ta)設計(ji)者十分(fen)努力地重視(shi)每個細節(jie)，現(xian)在奧迪已經可以讓這(zhe)款緊湊型車擁有(you)更多的(de)力量，同(tong)時融合(he)了(le)它(ta)的(de)外觀造型以及其人體工程學。奧迪A3的(de)底(di)盤設計(ji)非常(chang)周到，前(qian)懸架(jia)為麥克弗遜式，后橋(qiao)為扭轉、曲(qu)柄(bing)式結構帶分(fen)開(kai)布置的(de)彈簧和減振器，除了(le)操縱性極(ji)佳外，后懸架(jia)布置的(de)空間利(li)用率也很高(gao)(gao)(gao)，因此載貨面積在同(tong)級車中(zhong)出類拔萃。所有(you)A3系(xi)列車型，前(qian)后制動(dong)(dong)均為盤式，前(qian)制動(dong)(dong)帶通風槽。
