21、動(dòng)器，則基本維持原二代產(chǎn)品的結(jié)構(gòu)；若采用盤式制動(dòng)器，則要配置專用的后輪駐車制動(dòng)器。</p><p>　　就盤式制動(dòng)器而言，存有帶駐車制動(dòng)結(jié)構(gòu)的盤式制動(dòng)器，其駐車制動(dòng)力也作用在制動(dòng)盤兩側(cè)工作表面上，這種制動(dòng)器結(jié)構(gòu)復(fù)雜，可靠性相對(duì)稍差。都靈-V汽車為配用雙活塞滑動(dòng)前盤式制動(dòng)器須要，專門設(shè)置了后駐車制動(dòng)器。使其駐車制動(dòng)力作用在制動(dòng)盤的內(nèi)鼓工作表面上，這樣使制動(dòng)盤具有兩種分開(kāi)的摩擦表面，壽命可以提高，制動(dòng)鉗的結(jié)構(gòu)也相應(yīng)簡(jiǎn)

22、化。</p><p>　　都靈-V汽車的后輪駐車制動(dòng)裝置，由機(jī)械式操縱和專用候駐車制動(dòng)器兩大部分組成（制動(dòng)盤為行車、駐車制動(dòng)器共用件）。</p><p>　　1、機(jī)械式操縱機(jī)構(gòu) 基本維持原二代產(chǎn)品的結(jié)構(gòu)，主要組成件有手柄、前鋼絲拉索、棘齒板、調(diào)整螺套、鎖緊螺母、后鋼絲拉索及導(dǎo)盤等。</p><p>　　2、專用駐車制動(dòng)器結(jié)構(gòu)和原理 與后盤式制動(dòng)器相配的專用駐車制動(dòng)器

24、作用在專用駐車制動(dòng)器的制動(dòng)底板支架上，另有二只安裝孔，以便裝置后制動(dòng)鉗總成。帶內(nèi)鼓的后制動(dòng)盤將和輪毅、后專用駐車制動(dòng)器、制動(dòng)鉗總成等有序地組合在一起。</p><p>　　3、專用后駐車制動(dòng)器的駐車分解與合成當(dāng)拆</p><p>　　除了后輪毅、后制動(dòng)盤等若干零部件后，即可對(duì)專用駐車制動(dòng)器進(jìn)行分解與合成，基本工藝步驟如下:</p><p>　　·從前后摩擦
