扭矩傳感器簡介

在方(fang)向(xiang)盤下邊(bian)的(de)方(fang)向(xiang)桿上找(zhao)到助力(li)(li)電(dian)機，電(dian)機上一(yi)(yi)般有一(yi)(yi)個(ge)小鐵蓋(gai)護著的(de)、帶(dai)(dai)四(si)根線（帶(dai)(dai)有一(yi)(yi)個(ge)插頭）的(de)就是(shi)轉(zhuan)向(xiang)助力(li)(li)扭矩(ju)傳感器，拆下小鐵蓋(gai)就能看到。

電(dian)(dian)(dian)動(dong)(dong)(dong)助力轉向系(xi)(xi)統主要由扭(niu)矩(ju)(ju)傳感(gan)器，車(che)速(su)傳感(gan)器，電(dian)(dian)(dian)動(dong)(dong)(dong)機，減速(su)機構與電(dian)(dian)(dian)子控(kong)(kong)制單元(yuan)等組成(cheng)。該系(xi)(xi)統通過(guo)扭(niu)矩(ju)(ju)傳感(gan)器感(gan)知駕(jia)駛員在轉向操(cao)作(zuo)時方向盤產生的(de)扭(niu)矩(ju)(ju)力和轉向角度，就會把操(cao)控(kong)(kong)信(xin)息轉換成(cheng)數字信(xin)號(hao)輸入到(dao)控(kong)(kong)制單元(yuan)，再經過(guo)控(kong)(kong)制單元(yuan)對(dui)這(zhe)些信(xin)號(hao)進(jin)行運算得到(dao)一個(ge)最(zui)佳(jia)的(de)力矩(ju)(ju)最(zui)后控(kong)(kong)制驅使電(dian)(dian)(dian)動(dong)(dong)(dong)機工(gong)作(zuo)。以上就是(shi)整(zheng)個(ge)電(dian)(dian)(dian)動(dong)(dong)(dong)助力系(xi)(xi)統構成(cheng)和工(gong)作(zuo)的(de)過(guo)程，不(bu)難看(kan)出扭(niu)矩(ju)(ju)傳感(gan)器在電(dian)(dian)(dian)動(dong)(dong)(dong)助力系(xi)(xi)統中是(shi)最(zui)為(wei)重要的(de)器件之(zhi)一。

扭矩傳感器的作用

扭(niu)矩傳感(gan)器在(zai)電(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)向系統(tong)(tong)(tong)中的作(zuo)用(yong)(yong)電(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)向系統(tong)(tong)(tong)可以稱之(zhi)為EPS，它(ta)(ta)就是一種(zhong)直接依靠電(dian)機(ji)提供輔助(zhu)(zhu)(zhu)扭(niu)矩的動(dong)(dong)(dong)力(li)(li)轉(zhuan)(zhuan)向系統(tong)(tong)(tong)。在(zai)整個系統(tong)(tong)(tong)中，扭(niu)矩傳感(gan)器起到決定(ding)性作(zuo)用(yong)(yong)。與(yu)傳統(tong)(tong)(tong)的液壓助(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)向系統(tong)(tong)(tong)不同(tong)的是電(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)(li)轉(zhuan)(zhuan)向系統(tong)(tong)(tong)具有性能應用(yong)(yong)上更(geng)大的優(you)勢(shi)。它(ta)(ta)不光在(zai)需(xu)要轉(zhuan)(zhuan)向時才啟(qi)動(dong)(dong)(dong)電(dian)機(ji)產生助(zhu)(zhu)(zhu)力(li)(li)，這樣能大大的減少發動(dong)(dong)(dong)機(ji)燃油消耗。電(dian)動(dong)(dong)(dong)助(zhu)(zhu)(zhu)力(li)(li)能在(zai)各種(zhong)行駛(shi)工(gong)況下(xia)提供最佳助(zhu)(zhu)(zhu)力(li)(li)，減小由路面不平(ping)所引起電(dian)動(dong)(dong)(dong)機(ji)的輸(shu)出轉(zhuan)(zhuan)矩通過(guo)傳動(dong)(dong)(dong)裝(zhuang)置的作(zuo)用(yong)(yong)而助(zhu)(zhu)(zhu)力(li)(li)向系的擾動(dong)(dong)(dong)，改(gai)善汽(qi)車的轉(zhuan)(zhuan)向特(te)性，提高汽(qi)車的主動(dong)(dong)(dong)安(an)全性。和液壓助(zhu)(zhu)(zhu)力(li)(li)相比(bi)沒有液壓回路，調整和檢(jian)測更(geng)容易，裝(zhuang)配自動(dong)(dong)(dong)化程(cheng)度更(geng)高，且可通過(guo)設置不同(tong)的程(cheng)序，快速以及不同(tong)車型匹(pi)配，縮短生產和開(kai)發周期(qi)。

扭矩傳感器的作(zuo)用是測量動態扭矩和靜態扭矩，其檢測穩定性、抗干擾性，以及(ji)精度都很好，每(mei)次使(shi)用不需要(yao)調整為零。

馬自達MPV(進口)簡介

馬自達MPV5空間變化靈活，獨特的6+1空間布局是其最大賣點；車身高，視野好；外型漂亮動感，時尚前衛；內飾配置不多，乘坐舒適便利；動力一般；具有一定的操控樂趣；裝配工藝整體優良，但也有網友反映胎噪較大問題。

新款馬自達5新增的雙側電動滑動門是其賣點之一，車門滑軌和大尺寸尾燈融為一體，最大限度的減小了滑軌對動感外形的影響。

輪胎方面，馬自達5選用了跟車身一樣動感時尚的旋風式鋁合金輪轂，輪胎尺寸和逸致相同也是205/60 R16，輪胎品牌為東洋（TOYO）。
