四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)（4 Wheel Drive)主變(bian)速器(qi)通過一(yi)個(ge)輔助變(bian)速器(qi)將動(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)(li)傳送(song)到前(qian)輪(lun)和后輪(lun). 輔助變(bian)速器(qi)通常(chang)(chang)有三(san)檔(dang)選擇； 空(kong)檔(dang)，四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)低(di)檔(dang)。空(kong)檔(dang)時(shi)，四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)就(jiu)變(bian)成了(le)兩輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)。四輪(lun)驅(qu)(qu)(qu) 動(dong)(dong)(dong)(dong)(dong)(dong)(dong)適合于(yu)(yu)惡劣(lie)的(de)路面(mian)駕駛，例如，雨(yu)雪天(tian)和多沙石路面(mian)。四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)低(di)檔(dang)則(ze)適合高難度(du)的(de)越野駕駛。全輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong) (All Wheel Drive)全輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)是(shi)四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)一(yi)種(zhong). 它(ta)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)將發動(dong)(dong)(dong)(dong)(dong)(dong)(dong) 機提(ti)供的(de) 扭矩(ju)分(fen)送(song)到前(qian)輪(lun)和后輪(lun)，不(bu)需要手(shou)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)去調整，也沒有低(di)檔(dang)選擇。全輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong) 減低(di)了(le)車(che)(che)輪(lun)打滑的(de)程(cheng)度(du)，改(gai)善了(le)駕駛者(zhe)的(de)控車(che)(che)能力(li)(li)。全輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)通常(chang)(chang)是(shi)一(yi)種(zhong) 正常(chang)(chang)路面(mian)駕駛系統，并不(bu)設計用于(yu)(yu)越野駕駛。

維(wei)(wei)修費用低(di)也是(shi)(shi)后(hou)輪(lun)(lun)(lun)(lun)驅(qu)動(dong)的一個(ge)優點，盡(jin)管由于構造和車(che)(che)型(xing)的不同，這種費用將會有很大(da)的差別。但是(shi)(shi)如果你(ni)的變速器出了故障(zhang)，對(dui)(dui)于后(hou)輪(lun)(lun)(lun)(lun)驅(qu)動(dong)的汽(qi)車(che)(che)就(jiu)不需要對(dui)(dui)差速器進行維(wei)(wei)修，但是(shi)(shi)對(dui)(dui)于前輪(lun)(lun)(lun)(lun)驅(qu)動(dong)的汽(qi)車(che)(che)來說也許就(jiu)有這個(ge)必要了，因(yin)為這兩(liang)個(ge)部件是(shi)(shi)做在一起(qi)的。不過(guo)經(jing)過(guo)幾十年的發展，前輪(lun)(lun)(lun)(lun)驅(qu)動(dong)汽(qi)車(che)(che)的可靠性也已有了很大(da)的發展，維(wei)(wei)修費用的高也許已經(jing)并不是(shi)(shi)一個(ge)大(da)的問題了。

后輪驅動的缺(que)點也是(shi)顯(xian)而易見(jian)的，比如相對(dui)高的裝(zhuang)配和制造成本(ben)，更(geng)(geng)多(duo)的故障，相對(dui)狹小的室內(nei)空間等等。現在，更(geng)(geng)多(duo)的汽車都是(shi)使用的獨立后懸掛系統，這樣設計師在設計時就可以將車體與差速器和傳動軸靠的更(geng)(geng)近，從(cong)而可以增(zeng)大室內(nei)空間。

中特重工~四輪一帶生產廠家

驅動輪的工藝流程操作如下：

      鍛造→熱處理→粗精車→鉆(zhan)孔(kong)（安裝孔(kong)）→倒角→打磨→修補(bu)→噴漆→包(bao)裝入庫。四輪一帶

鏈條工藝流程操作如下：

      下料→銑雙面→鉆孔→倒(dao)角→銑內邊四方(fang)孔。四輪一帶

     現在湖北中特工程機械有限公司的兩條鍛造生產線已經安裝完畢，正在調試階段，4月爭取正常生產，這對公司的發會起到更大的幫助。四輪一帶

      履帶(dai)機械底盤零部件產品需求旺盛，市場(chang)前景非常樂觀，而且將有較大發展。四輪一帶(dai)
