扭矩傳感器簡介

在方向盤(pan)下邊的方向桿上找到(dao)助力電機(ji)，電機(ji)上一般有(you)一個(ge)(ge)小鐵蓋(gai)護(hu)著的、帶四根線（帶有(you)一個(ge)(ge)插頭(tou)）的就是(shi)轉(zhuan)向助力扭矩傳感器，拆下小鐵蓋(gai)就能看到(dao)。

電(dian)(dian)動(dong)(dong)助力轉(zhuan)向(xiang)系(xi)統(tong)(tong)主要(yao)由(you)扭矩(ju)傳感器(qi)，車速(su)傳感器(qi)，電(dian)(dian)動(dong)(dong)機，減速(su)機構與電(dian)(dian)子控(kong)(kong)制單(dan)(dan)元等組成。該(gai)系(xi)統(tong)(tong)通過扭矩(ju)傳感器(qi)感知駕駛員在轉(zhuan)向(xiang)操作(zuo)時(shi)方向(xiang)盤產生的扭矩(ju)力和轉(zhuan)向(xiang)角度(du)，就會把操控(kong)(kong)信息轉(zhuan)換成數字信號輸(shu)入(ru)到(dao)控(kong)(kong)制單(dan)(dan)元，再經(jing)過控(kong)(kong)制單(dan)(dan)元對(dui)這些信號進行運(yun)算(suan)得到(dao)一個最(zui)(zui)佳的力矩(ju)最(zui)(zui)后控(kong)(kong)制驅使電(dian)(dian)動(dong)(dong)機工作(zuo)。以上就是整(zheng)個電(dian)(dian)動(dong)(dong)助力系(xi)統(tong)(tong)構成和工作(zuo)的過程，不難看出扭矩(ju)傳感器(qi)在電(dian)(dian)動(dong)(dong)助力系(xi)統(tong)(tong)中是最(zui)(zui)為重要(yao)的器(qi)件之一。

扭矩傳感器的作用

扭矩傳(chuan)(chuan)感器在電(dian)(dian)動(dong)助(zhu)(zhu)(zhu)(zhu)力(li)轉(zhuan)向系(xi)統(tong)中的(de)(de)(de)作用(yong)電(dian)(dian)動(dong)助(zhu)(zhu)(zhu)(zhu)力(li)轉(zhuan)向系(xi)統(tong)可以(yi)稱(cheng)之(zhi)為EPS，它就是(shi)一種直接依靠電(dian)(dian)機(ji)提(ti)供(gong)輔助(zhu)(zhu)(zhu)(zhu)扭矩的(de)(de)(de)動(dong)力(li)轉(zhuan)向系(xi)統(tong)。在整個系(xi)統(tong)中，扭矩傳(chuan)(chuan)感器起到決定性作用(yong)。與(yu)傳(chuan)(chuan)統(tong)的(de)(de)(de)液(ye)壓(ya)助(zhu)(zhu)(zhu)(zhu)力(li)轉(zhuan)向系(xi)統(tong)不(bu)(bu)同(tong)的(de)(de)(de)是(shi)電(dian)(dian)動(dong)助(zhu)(zhu)(zhu)(zhu)力(li)轉(zhuan)向系(xi)統(tong)具(ju)有性能應用(yong)上(shang)更大的(de)(de)(de)優勢。它不(bu)(bu)光在需要轉(zhuan)向時才啟動(dong)電(dian)(dian)機(ji)產生助(zhu)(zhu)(zhu)(zhu)力(li)，這樣能大大的(de)(de)(de)減少發(fa)(fa)動(dong)機(ji)燃油消耗。電(dian)(dian)動(dong)助(zhu)(zhu)(zhu)(zhu)力(li)能在各種行(xing)駛工況下提(ti)供(gong)最佳助(zhu)(zhu)(zhu)(zhu)力(li)，減小由路面不(bu)(bu)平(ping)所引起電(dian)(dian)動(dong)機(ji)的(de)(de)(de)輸出轉(zhuan)矩通(tong)過傳(chuan)(chuan)動(dong)裝置的(de)(de)(de)作用(yong)而助(zhu)(zhu)(zhu)(zhu)力(li)向系(xi)的(de)(de)(de)擾動(dong)，改善汽(qi)車(che)的(de)(de)(de)轉(zhuan)向特性，提(ti)高汽(qi)車(che)的(de)(de)(de)主動(dong)安全性。和液(ye)壓(ya)助(zhu)(zhu)(zhu)(zhu)力(li)相(xiang)比沒有液(ye)壓(ya)回路，調(diao)整和檢測更容易，裝配自動(dong)化(hua)程度(du)更高，且可通(tong)過設置不(bu)(bu)同(tong)的(de)(de)(de)程序，快速(su)以(yi)及不(bu)(bu)同(tong)車(che)型匹(pi)配，縮短(duan)生產和開發(fa)(fa)周期。

扭矩(ju)傳(chuan)感(gan)器(qi)的作用是測量動態扭矩(ju)和靜態扭矩(ju)，其檢測穩定性(xing)、抗干擾(rao)性(xing)，以及精度(du)都很好，每次(ci)使用不需要調整為零。

捷豹XF簡介

作(zuo)為捷(jie)豹的(de)(de)中大(da)型豪華轎車，分為標(biao)準(zhun)版、旅行版及XFR性能版。在設計上，捷(jie)豹XF更趨向于(yu)XK的(de)(de)造車理(li)念，充(chong)滿現(xian)代感的(de)(de)氣(qi)(qi)息：大(da)氣(qi)(qi)的(de)(de)前臉、流暢的(de)(de)車身線條，配以鑲嵌在進氣(qi)(qi)隔柵中間的(de)(de)豹頭徽標(biao)，彰顯了該車的(de)(de)不(bu)凡的(de)(de)氣(qi)(qi)勢。捷(jie)豹XF內(nei)部空(kong)間非常寬敞，可輕松容納五名成年人，與(yu)(yu)外觀風格(ge)相得(de)益彰。XF也(ye)擁(yong)有精湛的(de)(de)手(shou)工技術，帶給人尊崇的(de)(de)駕(jia)乘體驗。此外，循序式換檔系(xi)統(tong)通過方向盤上的(de)(de)換檔撥片為駕(jia)駛員提供(gong)了一觸式手(shou)動(dong)換檔功能；駕(jia)駛者可以選(xuan)擇21種變速模式，以使節氣(qi)(qi)門進程(cheng)和換檔策略與(yu)(yu)實際(ji)路況和駕(jia)駛環境(jing)相適應。
