前制動片(剎車片)簡介

制動(dong)(dong)片(pian)(pian)，也叫(jiao)剎車(che)片(pian)(pian)，在汽車(che)的(de)(de)制動(dong)(dong)系(xi)統中(zhong)，制動(dong)(dong)片(pian)(pian)是(shi)(shi)(shi)最關鍵的(de)(de)安全(quan)零件(jian)，所(suo)有剎車(che)效(xiao)果的(de)(de)好(hao)壞都是(shi)(shi)(shi)制動(dong)(dong)片(pian)(pian)起著決(jue)定性的(de)(de)作用(yong)。制動(dong)(dong)片(pian)(pian)一般由(you)鋼板、粘結(jie)隔(ge)(ge)熱層和摩擦(ca)塊構成(cheng)，其中(zhong)隔(ge)(ge)熱層是(shi)(shi)(shi)由(you)不傳(chuan)熱的(de)(de)材料組(zu)成(cheng)，目的(de)(de)是(shi)(shi)(shi)隔(ge)(ge)熱；摩擦(ca)塊是(shi)(shi)(shi)由(you)摩擦(ca)材料、黏(nian)合劑組(zu)成(cheng)，制動(dong)(dong)時被擠壓在制動(dong)(dong)盤和制動(dong)(dong)鼓(gu)上(shang)產生摩擦(ca)，從而達到車(che)輛減速剎車(che)的(de)(de)目的(de)(de)

制動(dong)(dong)片在使用(yong)過程中，由于(yu)摩擦(ca)作用(yong)，摩擦(ca)塊(kuai)會逐漸被磨損(sun)，摩擦(ca)材料(liao)使用(yong)完后要及(ji)時更換制動(dong)(dong)片，否(fou)則鋼(gang)板與制動(dong)(dong)盤就會直接(jie)接(jie)觸，最(zui)終(zhong)會喪(sang)失(shi)制動(dong)(dong)效果(guo)并(bing)損(sun)壞制動(dong)(dong)盤，影響行(xing)(xing)車(che)安全。為(wei)了您的行(xing)(xing)車(che)安全，請定期檢(jian)查(cha)和(he)更換制動(dong)(dong)片。
汽車(che)摩擦(ca)材料是摩擦(ca)式(接(jie)(jie)觸式)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)器(qi)(qi)和離合器(qi)(qi)用(yong)以制(zhi)(zhi)(zhi)動(dong)(dong)(dong)和傳動(dong)(dong)(dong)的(de)(de)(de)關鍵材料。汽車(che)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)片是車(che)輛制(zhi)(zhi)(zhi)動(dong)(dong)(dong)傳動(dong)(dong)(dong)的(de)(de)(de)關鍵部(bu)件(jian)，直接(jie)(jie)影響汽車(che)的(de)(de)(de)行(xing)駛安(an)全(quan)性能(neng)。21世紀的(de)(de)(de)汽車(che)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)器(qi)(qi)的(de)(de)(de)主要(yao)課題是更安(an)全(quan)、輕量化和合乎環境(jing)保(bao)護要(yao)求(qiu)，這不僅需要(yao)進行(xing)新(xin)材料開發，而且需要(yao)采用(yong)新(xin)結(jie)構(gou)、新(xin)系統(tong)，以便大幅度提高制(zhi)(zhi)(zhi)動(dong)(dong)(dong)器(qi)(qi)的(de)(de)(de)綜合使(shi)(shi)用(yong)性能(neng)和實(shi)現(xian)輕量化。它的(de)(de)(de)性能(neng)好壞，直接(jie)(jie)影響著汽車(che)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)系統(tong)能(neng)否正常使(shi)(shi)用(yong)，從而關乎到汽車(che)舒適性、安(an)全(quan)性等性能(neng)的(de)(de)(de)實(shi)現(xian)。
汽車(che)摩(mo)擦(ca)材(cai)(cai)料(liao)生(sheng)產工(gong)(gong)藝按照加工(gong)(gong)溫(wen)度(du)區分，大(da)致可以分為(wei)三類：熱壓(ya)(ya)(ya)(ya)工(gong)(gong)藝、冷(leng)壓(ya)(ya)(ya)(ya)工(gong)(gong)藝和溫(wen)壓(ya)(ya)(ya)(ya)工(gong)(gong)藝。熱壓(ya)(ya)(ya)(ya)工(gong)(gong)藝應用(yong)歷史悠久、技術(shu)成熟、適(shi)用(yong)面廣，現階段為(wei)國內外大(da)部(bu)分摩(mo)擦(ca)材(cai)(cai)料(liao)生(sheng)產廠家所應用(yong)。冷(leng)壓(ya)(ya)(ya)(ya)和溫(wen)壓(ya)(ya)(ya)(ya)工(gong)(gong)藝都(dou)屬于(yu)低溫(wen)成型工(gong)(gong)藝，屬于(yu)新型摩(mo)擦(ca)材(cai)(cai)料(liao)生(sheng)產工(gong)(gong)藝，性能較為(wei)優(you)越，雖然這些新工(gong)(gong)藝的研究取得了一定(ding)成績，但尚且(qie)屬于(yu)探索階段，技術(shu)還(huan)不成熟，還(huan)有待深入開展

前制動片的拆裝安裝方法：

前制動(dong)片的拆裝(zhuang)安裝(zhuang)方法(fa)：

更換(huan)剎(cha)(cha)車(che)皮我們會用到千(qian)斤頂、合適的套筒(tong)扳手(shou)、梅花(hua)扳手(shou)、螺絲刀、砂紙、潤滑脂(zhi)等(deng)。所有工具和剎(cha)(cha)車(che)皮零件都能通過網購買到。有些(xie)工具車(che)輛一(yi)般會配備，如千(qian)斤頂以及拆(chai)輪胎的十字(zi)套筒(tong)；而一(yi)些(xie)則(ze)需自行購買。

寶馬118i簡介

寶馬118i是寶馬公司產的一款性能跑車，搭載1.6升增壓發動機，采用BMW TwinPower Turbo技術，雙渦管單渦輪增壓、高精度直噴系統、VALVETRONIC電子氣門控制及Double-VANOS雙凸輪軸可變氣門正時系統，最大功率125千瓦，最大扭矩250牛米。
增壓發動機效果優于ZF出品的8擋自動變速器，緊密、合理的齒比設定保證高效動力傳輸，激烈駕駛時快速、大幅的降擋動作，常規駕駛時，平順的換擋“悄無聲息",靜音不錯。
