扭矩傳感器簡介

在方(fang)向(xiang)盤下邊的方(fang)向(xiang)桿上找到助(zhu)力電(dian)(dian)機，電(dian)(dian)機上一(yi)般有一(yi)個(ge)小鐵蓋護著的、帶(dai)四根線(xian)（帶(dai)有一(yi)個(ge)插(cha)頭）的就(jiu)是(shi)轉向(xiang)助(zhu)力扭矩傳感器(qi)，拆下小鐵蓋就(jiu)能看(kan)到。

電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)助力(li)(li)轉向系(xi)統(tong)(tong)主要由扭矩(ju)傳感(gan)器，車速傳感(gan)器，電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)，減速機(ji)構與電(dian)(dian)(dian)子(zi)控制(zhi)單(dan)(dan)元(yuan)等組成。該系(xi)統(tong)(tong)通過扭矩(ju)傳感(gan)器感(gan)知駕駛員在轉向操作時方向盤產生的(de)扭矩(ju)力(li)(li)和轉向角度，就會把操控信息轉換成數(shu)字信號(hao)輸(shu)入(ru)到控制(zhi)單(dan)(dan)元(yuan)，再經過控制(zhi)單(dan)(dan)元(yuan)對這些信號(hao)進行運算得到一(yi)個(ge)最(zui)佳的(de)力(li)(li)矩(ju)最(zui)后(hou)控制(zhi)驅使電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)工(gong)作。以(yi)上就是整個(ge)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)助力(li)(li)系(xi)統(tong)(tong)構成和工(gong)作的(de)過程(cheng)，不難看(kan)出扭矩(ju)傳感(gan)器在電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)助力(li)(li)系(xi)統(tong)(tong)中是最(zui)為重要的(de)器件之一(yi)。

扭矩傳感器的作用

扭(niu)矩(ju)傳(chuan)感器在(zai)電(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)向(xiang)(xiang)系(xi)統(tong)(tong)中的(de)(de)作(zuo)(zuo)用電(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)向(xiang)(xiang)系(xi)統(tong)(tong)可以稱之為(wei)EPS，它(ta)就是(shi)(shi)一種(zhong)直接依靠電(dian)(dian)機(ji)(ji)提(ti)供輔助(zhu)(zhu)(zhu)扭(niu)矩(ju)的(de)(de)動(dong)(dong)(dong)力(li)(li)轉(zhuan)向(xiang)(xiang)系(xi)統(tong)(tong)。在(zai)整個系(xi)統(tong)(tong)中，扭(niu)矩(ju)傳(chuan)感器起到決定性(xing)作(zuo)(zuo)用。與傳(chuan)統(tong)(tong)的(de)(de)液(ye)壓助(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)向(xiang)(xiang)系(xi)統(tong)(tong)不(bu)同的(de)(de)是(shi)(shi)電(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)向(xiang)(xiang)系(xi)統(tong)(tong)具有(you)性(xing)能(neng)應用上更大(da)的(de)(de)優勢。它(ta)不(bu)光(guang)在(zai)需要轉(zhuan)向(xiang)(xiang)時才啟動(dong)(dong)(dong)電(dian)(dian)機(ji)(ji)產(chan)生助(zhu)(zhu)(zhu)力(li)(li)，這樣能(neng)大(da)大(da)的(de)(de)減少(shao)發動(dong)(dong)(dong)機(ji)(ji)燃(ran)油消耗(hao)。電(dian)(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)(li)能(neng)在(zai)各種(zhong)行駛工況下提(ti)供最佳助(zhu)(zhu)(zhu)力(li)(li)，減小(xiao)由路面不(bu)平所引(yin)起電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)的(de)(de)輸出轉(zhuan)矩(ju)通過傳(chuan)動(dong)(dong)(dong)裝置的(de)(de)作(zuo)(zuo)用而助(zhu)(zhu)(zhu)力(li)(li)向(xiang)(xiang)系(xi)的(de)(de)擾動(dong)(dong)(dong)，改善汽車的(de)(de)轉(zhuan)向(xiang)(xiang)特性(xing)，提(ti)高汽車的(de)(de)主動(dong)(dong)(dong)安(an)全性(xing)。和(he)液(ye)壓助(zhu)(zhu)(zhu)力(li)(li)相比(bi)沒有(you)液(ye)壓回路，調整和(he)檢(jian)測更容易，裝配自動(dong)(dong)(dong)化程度更高，且可通過設(she)置不(bu)同的(de)(de)程序，快(kuai)速以及不(bu)同車型(xing)匹配，縮(suo)短(duan)生產(chan)和(he)開發周期。

扭矩(ju)傳(chuan)感器的(de)作用(yong)是測(ce)量動態(tai)扭矩(ju)和靜態(tai)扭矩(ju)，其檢測(ce)穩定性、抗干(gan)擾性，以(yi)及精度都很好，每次使用(yong)不需要調整為零。

夏朗(進口)簡介

大眾(zhong)夏(xia)朗（sharan）是(shi)一(yi)(yi)款具有典型大眾(zhong)風格的車型，相比其它MPV，其底(di)盤特(te)別(bie)扎(zha)(zha)實，操控性也特(te)別(bie)出(chu)色，頗有歐(ou)洲車的扎(zha)(zha)實和厚重。大眾(zhong)夏(xia)朗車系自(zi)1996年第(di)一(yi)(yi)代(dai)夏(xia)朗全面生(sheng)產以來，一(yi)(yi)直占據著德國市(shi)場最(zui)暢銷mpv的位置。在(zai)整個歐(ou)洲市(shi)場，夏(xia)朗在(zai)同級車中(zhong)的銷量也位列三甲。夏(xia)朗的超凡魅力足以證明大眾(zhong)汽車的設(she)計和制造理念(nian)是(shi)多么深入人心。
