四輪一帶-挖掘機四輪一帶-中特工程機械：

概述目前(qian)，2轎車的(de)(de)(de)4輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)裝置已經引進了(le)電子計算機(ji)控制系(xi)統，當前(qian)輪(lun)(lun)(lun)或后輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)時(shi)，車子隨時(shi)根(gen)據(ju)路(lu)(lu)面(mian)(mian)狀(zhuang)態的(de)(de)(de)反(fan)饋信息分配前(qian)后輪(lun)(lun)(lun)子的(de)(de)(de)動(dong)(dong)(dong)力，變為(wei)4輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)。4輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)又可以細分成4種(zhong)驅(qu)(qu)動(dong)(dong)(dong)模式：全時(shi)驅(qu)(qu)動(dong)(dong)(dong)（Full－Time）、分時(shi)驅(qu)(qu)動(dong)(dong)(dong)（Part-Time）、適時(shi)驅(qu)(qu)動(dong)(dong)(dong)（Real－Time）和(he)分時(shi)/適時(shi)混和(he)驅(qu)(qu)動(dong)(dong)(dong)。全時(shi)驅(qu)(qu)動(dong)(dong)(dong)全時(shi)驅(qu)(qu)動(dong)(dong)(dong)（Full－Time） 全時(shi)驅(qu)(qu)動(dong)(dong)(dong)的(de)(de)(de)特點(dian)就是(shi)無論怎么樣，永遠都保持(chi)四輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)模式，這(zhe)種(zhong)傳動(dong)(dong)(dong)系(xi)統都是(shi)不(bu)需要駕(jia)駛(shi)人選擇操作的(de)(de)(de)。行駛(shi)的(de)(de)(de)時(shi)將發(fa)動(dong)(dong)(dong)機(ji)輸出扭矩(ju)按50∶50 設定在前(qian)后輪(lun)(lun)(lun)上(shang)，使前(qian)后排車輪(lun)(lun)(lun)保持(chi)等量的(de)(de)(de)扭矩(ju)，遇到特別路(lu)(lu)面(mian)(mian)的(de)(de)(de)時(shi)候就可以自(zi)動(dong)(dong)(dong)將不(bu)同(tong)的(de)(de)(de)扭距分配到各(ge)個輪(lun)(lun)(lun)子上(shang)面(mian)(mian)。全時(shi)驅(qu)(qu)動(dong)(dong)(dong)系(xi)統具(ju)有(you)良好(hao)的(de)(de)(de)駕(jia)駛(shi)操控性(xing)和(he)行駛(shi)循跡性(xing)，不(bu)過缺點(dian)也是(shi)很明(ming)顯(xian)的(de)(de)(de)，那(nei)就是(shi)比較廢(fei)油，經濟性(xing)不(bu)夠(gou)好(hao)，而(er)且車輛(liang)沒(mei)有(you)任何(he)裝置來控制輪(lun)(lun)(lun)胎轉速的(de)(de)(de)差異，一(yi)旦(dan)一(yi)個輪(lun)(lun)(lun)胎離開地面(mian)(mian)就有(you)可能讓(rang)你(ni)無法前(qian)進。

四(si)(si)(si)輪(lun)驅(qu)(qu)動(dong)(dong)（4 Wheel Drive)主(zhu)變(bian)速器(qi)(qi)通(tong)過(guo)一個輔助(zhu)變(bian)速器(qi)(qi)將動(dong)(dong)力傳送(song)到前輪(lun)和后輪(lun). 輔助(zhu)變(bian)速器(qi)(qi)通(tong)常(chang)有三檔(dang)(dang)(dang)選擇(ze)； 空檔(dang)(dang)(dang)，四(si)(si)(si)輪(lun)驅(qu)(qu)動(dong)(dong)，四(si)(si)(si)輪(lun)驅(qu)(qu)動(dong)(dong)低檔(dang)(dang)(dang)。空檔(dang)(dang)(dang)時，四(si)(si)(si)輪(lun)驅(qu)(qu)動(dong)(dong)就變(bian)成了兩輪(lun)驅(qu)(qu)動(dong)(dong)。四(si)(si)(si)輪(lun)驅(qu)(qu) 動(dong)(dong)適合(he)于惡劣(lie)的路面駕(jia)駛(shi)(shi)，例(li)如，雨雪天和多沙石路面。四(si)(si)(si)輪(lun)驅(qu)(qu)動(dong)(dong)低檔(dang)(dang)(dang)則適合(he)高難度的越(yue)野駕(jia)駛(shi)(shi)。全輪(lun)驅(qu)(qu)動(dong)(dong) (All Wheel Drive)全輪(lun)驅(qu)(qu)動(dong)(dong)是四(si)(si)(si)輪(lun)驅(qu)(qu)動(dong)(dong)的一種. 它自動(dong)(dong)將發動(dong)(dong) 機提(ti)供的 扭矩分送(song)到前輪(lun)和后輪(lun)，不需要手動(dong)(dong)去調(diao)整(zheng)，也沒有低檔(dang)(dang)(dang)選擇(ze)。全輪(lun)驅(qu)(qu)動(dong)(dong) 減低了車輪(lun)打滑的程度，改善了駕(jia)駛(shi)(shi)者的控車能力。全輪(lun)驅(qu)(qu)動(dong)(dong)通(tong)常(chang)是一種 正常(chang)路面駕(jia)駛(shi)(shi)系統，并不設計用于越(yue)野駕(jia)駛(shi)(shi)。
