22、同大概可分為：普通矩形車廂和礦用鏟斗車廂普通矩形車廂用于散裝貨物運輸。其后板裝有自動開合機構，保證貨物順利卸出。普通矩形車廂板厚為：前板4到6mm，邊板4到8mm，后板5到8mm，底板6到12mm。</p><p>　　礦用鏟斗車廂則適用于大石塊等粒度較大貨物的運輸?？紤]到貨物的沖擊和碰幢，礦用鏟斗車廂的設計形狀較復雜，用料較厚。而且有些車型在底板上焊接一些角鋼，以增加車廂的剛度和抗沖擊能力。</p>

23、<p><b>　　2、舉升機構型式</b></p><p>　　舉升機構是自卸車的核心，是判別自卸車優(yōu)劣的首要指標。舉升機構的型式目前國內常見的有：F式三角架放大舉升機構、T式三角架放大舉升機構、雙缸舉升、前頂舉升和雙面?zhèn)确?lt;/p><p>　　三角架放大式舉升機構是目前國內使用最多的一種舉升方式，適用載重量8到40噸，車廂長度4.4到6米。優(yōu)點為結

25、單、車廂底板與主車架上平面的閉合高度可以很小，整車穩(wěn)定性好，液壓系統(tǒng)壓力較小，但前頂多級缸行程較大，造價很高。</p><p>　　雙面?zhèn)确簤焊资芰^好，行程較小，可實現雙面?zhèn)确?；但液壓管路較復雜，舉生翻車事故發(fā)生率較高。</p><p>　　自卸車工作原理：拿一個手動千斤頂來說它的工作原理，千斤頂是個最簡單的油缸了。通過手動增壓稈(液壓手動泵)使液壓油經過一個單項閥進入油缸，這時進入油

26、缸的液壓油因為單項閥的原因不能再倒退回來，逼迫缸桿向上，然后在做工繼續(xù)使液壓油不斷進入液壓缸，就這樣不斷上上升，要降的時候就打開液壓閥，使液壓油回到油箱。這是最簡單的工作原理，其它的都在這個基礎上改進。 自卸車油缸的材質：自卸車油缸原材料是一般的無縫鋼管，材質為硅錳。自卸車油缸的活塞帶極限的壓力是16兆帕，油缸的行程范圍從3830到8000不等。億力公司作為專業(yè)生產自卸車前置油缸的生產廠家，所產自卸車油缸具備油缸的一切特性。</p
