扭矩傳感器簡介

在(zai)方向盤下邊的方向桿上找到助力(li)電(dian)機，電(dian)機上一(yi)般有一(yi)個小鐵蓋(gai)護(hu)著的、帶四根線（帶有一(yi)個插頭）的就是(shi)轉向助力(li)扭矩傳感器，拆下小鐵蓋(gai)就能看(kan)到。

電(dian)(dian)(dian)動(dong)(dong)助(zhu)力轉向(xiang)系統(tong)主要由扭(niu)矩(ju)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)，車速傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)，電(dian)(dian)(dian)動(dong)(dong)機，減(jian)速機構(gou)與電(dian)(dian)(dian)子(zi)控(kong)制單(dan)元等組(zu)成(cheng)。該系統(tong)通過扭(niu)矩(ju)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)感(gan)知駕駛員在轉向(xiang)操作時方(fang)向(xiang)盤產(chan)生的(de)扭(niu)矩(ju)力和轉向(xiang)角度(du)，就會(hui)把操控(kong)信(xin)息轉換成(cheng)數字信(xin)號輸入(ru)到控(kong)制單(dan)元，再經過控(kong)制單(dan)元對這些信(xin)號進行運算得到一個最佳的(de)力矩(ju)最后控(kong)制驅使(shi)電(dian)(dian)(dian)動(dong)(dong)機工(gong)作。以上(shang)就是整(zheng)個電(dian)(dian)(dian)動(dong)(dong)助(zhu)力系統(tong)構(gou)成(cheng)和工(gong)作的(de)過程，不難看出扭(niu)矩(ju)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)在電(dian)(dian)(dian)動(dong)(dong)助(zhu)力系統(tong)中是最為重要的(de)器(qi)(qi)(qi)件之一。

扭矩傳感器的作用

扭矩(ju)傳感器在(zai)(zai)電(dian)(dian)(dian)動(dong)(dong)(dong)助力(li)轉向(xiang)(xiang)系(xi)(xi)統(tong)中的(de)(de)(de)(de)作(zuo)(zuo)用(yong)電(dian)(dian)(dian)動(dong)(dong)(dong)助力(li)轉向(xiang)(xiang)系(xi)(xi)統(tong)可以稱之為EPS，它就是一種直接依靠電(dian)(dian)(dian)機(ji)提(ti)供輔助扭矩(ju)的(de)(de)(de)(de)動(dong)(dong)(dong)力(li)轉向(xiang)(xiang)系(xi)(xi)統(tong)。在(zai)(zai)整(zheng)個(ge)系(xi)(xi)統(tong)中，扭矩(ju)傳感器起到決定性(xing)作(zuo)(zuo)用(yong)。與傳統(tong)的(de)(de)(de)(de)液(ye)壓(ya)助力(li)轉向(xiang)(xiang)系(xi)(xi)統(tong)不(bu)同(tong)的(de)(de)(de)(de)是電(dian)(dian)(dian)動(dong)(dong)(dong)助力(li)轉向(xiang)(xiang)系(xi)(xi)統(tong)具有性(xing)能應用(yong)上更(geng)大的(de)(de)(de)(de)優勢。它不(bu)光在(zai)(zai)需要轉向(xiang)(xiang)時才啟(qi)動(dong)(dong)(dong)電(dian)(dian)(dian)機(ji)產生助力(li)，這(zhe)樣能大大的(de)(de)(de)(de)減少(shao)發(fa)動(dong)(dong)(dong)機(ji)燃油(you)消耗。電(dian)(dian)(dian)動(dong)(dong)(dong)助力(li)能在(zai)(zai)各(ge)種行(xing)駛(shi)工況下提(ti)供最佳助力(li)，減小由路(lu)面不(bu)平(ping)所引起電(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)的(de)(de)(de)(de)輸(shu)出轉矩(ju)通(tong)過(guo)傳動(dong)(dong)(dong)裝(zhuang)置的(de)(de)(de)(de)作(zuo)(zuo)用(yong)而助力(li)向(xiang)(xiang)系(xi)(xi)的(de)(de)(de)(de)擾動(dong)(dong)(dong)，改善汽(qi)車(che)的(de)(de)(de)(de)轉向(xiang)(xiang)特性(xing)，提(ti)高汽(qi)車(che)的(de)(de)(de)(de)主(zhu)動(dong)(dong)(dong)安(an)全性(xing)。和(he)液(ye)壓(ya)助力(li)相比沒有液(ye)壓(ya)回(hui)路(lu)，調(diao)整(zheng)和(he)檢測更(geng)容(rong)易(yi)，裝(zhuang)配自動(dong)(dong)(dong)化程(cheng)度(du)更(geng)高，且可通(tong)過(guo)設置不(bu)同(tong)的(de)(de)(de)(de)程(cheng)序，快速以及(ji)不(bu)同(tong)車(che)型(xing)匹配，縮短生產和(he)開(kai)發(fa)周期。

扭矩傳感器的(de)作用是測(ce)(ce)量動態(tai)扭矩和靜(jing)態(tai)扭矩，其檢(jian)測(ce)(ce)穩定性、抗干擾性，以及精度都很(hen)好，每次使用不需要調整為零。

大眾凌度簡介

凌渡(du)這款汽車(che)的(de)(de)動力說實話并不是(shi)(shi)特別(bie)(bie)強勁，起(qi)步的(de)(de)時候有點(dian)肉，但是(shi)(shi)提(ti)速的(de)(de)時候汽車(che)的(de)(de)反應速度還(huan)是(shi)(shi)比(bi)較快的(de)(de)，因(yin)為我(wo)買(mai)車(che)主(zhu)要就(jiu)是(shi)(shi)為了方便日常上(shang)下班(ban)，所以對(dui)于汽車(che)的(de)(de)動力要求(qiu)并不是(shi)(shi)特別(bie)(bie)高，凌渡(du)這款汽車(che)完(wan)全可以滿(man)足(zu)我(wo)的(de)(de)需(xu)要。凌度的(de)(de)耗(hao)油(you)量比(bi)較低(di)，以我(wo)的(de)(de)經(jing)(jing)濟條件(jian)完(wan)全可以負擔得起(qi)。而且朋友告訴我(wo)說，新(xin)車(che)在經(jing)(jing)過磨合(he)期以后耗(hao)油(you)量會(hui)降(jiang)低(di)，所以估計等再用一段時間(jian)零(ling)度的(de)(de)耗(hao)油(you)量會(hui)再低(di)一點(dian)，讓(rang)我(wo)特別(bie)(bie)滿(man)意(yi)。
