四(si)(si)輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)（4 Wheel Drive)主變(bian)速(su)器通過一個輔助變(bian)速(su)器將動(dong)(dong)(dong)(dong)(dong)力(li)傳送(song)到(dao)前輪(lun)(lun)(lun)(lun)(lun)和后輪(lun)(lun)(lun)(lun)(lun). 輔助變(bian)速(su)器通常有三檔(dang)(dang)選擇； 空(kong)檔(dang)(dang)，四(si)(si)輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)，四(si)(si)輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)低(di)檔(dang)(dang)。空(kong)檔(dang)(dang)時，四(si)(si)輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)就變(bian)成了(le)兩輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)。四(si)(si)輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu) 動(dong)(dong)(dong)(dong)(dong)適合(he)于惡(e)劣(lie)的(de)路面(mian)(mian)駕駛，例如，雨雪天(tian)和多沙(sha)石路面(mian)(mian)。四(si)(si)輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)低(di)檔(dang)(dang)則適合(he)高難度(du)的(de)越野駕駛。全輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong) (All Wheel Drive)全輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)是(shi)四(si)(si)輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)的(de)一種(zhong)(zhong). 它(ta)自動(dong)(dong)(dong)(dong)(dong)將發動(dong)(dong)(dong)(dong)(dong) 機提供的(de) 扭矩分送(song)到(dao)前輪(lun)(lun)(lun)(lun)(lun)和后輪(lun)(lun)(lun)(lun)(lun)，不需要(yao)手動(dong)(dong)(dong)(dong)(dong)去調整，也沒有低(di)檔(dang)(dang)選擇。全輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong) 減(jian)低(di)了(le)車(che)輪(lun)(lun)(lun)(lun)(lun)打滑的(de)程度(du)，改善了(le)駕駛者的(de)控(kong)車(che)能(neng)力(li)。全輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)通常是(shi)一種(zhong)(zhong) 正常路面(mian)(mian)駕駛系統，并不設計用于越野駕駛。

 四輪一帶~挖掘機行業特點

挖掘機的安全性能：

       歐(ou)洲(zhou)和北美對工程(cheng)機械(xie)安(an)全性(xing)有嚴格的(de)法律規(gui)定，設備(bei)的(de)安(an)全性(xing)能(neng)能(neng)夠給操(cao)作人(ren)員提供(gong)安(an)心作業的(de)環境，提高操(cao)作人(ren)員的(de)安(an)全性(xing)。小型挖掘(jue)機的(de)安(an)全性(xing)能(neng)主要體現在駕駛室的(de)ROPS/FOPS設計上(shang)，在駕駛室的(de)試驗中應滿足以下性(xing)能(neng)要求：①可滿足必須的(de)能(neng)量吸收;②可滿足必須的(de)抗荷載;③可確保乘(cheng)員安(an)全區域;④無加固構(gou)件的(de)異常(chang)(破(po)損、龜裂)。四(si)輪(lun)一帶

       在誤操作(zuo)(zuo)(zuo)安(an)(an)全(quan)(quan)保(bao)護方面主要采用(yong)的技術(shu)有：中位(wei)啟動(dong)(dong)保(bao)護─安(an)(an)全(quan)(quan)鎖(suo)(suo)(suo)桿(gan)在鎖(suo)(suo)(suo)定狀態下才能啟動(dong)(dong)發動(dong)(dong)機;安(an)(an)全(quan)(quan)手柄操作(zuo)(zuo)(zuo)模式——如果(guo)安(an)(an)全(quan)(quan)鎖(suo)(suo)(suo)處于鎖(suo)(suo)(suo)定狀態，操作(zuo)(zuo)(zuo)手柄及行駛手柄的操作(zuo)(zuo)(zuo)無效，可防(fang)止誤操作(zuo)(zuo)(zuo)導致事故;回(hui)轉(zhuan)自(zi)動(dong)(dong)鎖(suo)(suo)(suo)定——發動(dong)(dong)機熄火時(shi)，回(hui)轉(zhuan)馬達將自(zi)動(dong)(dong)鎖(suo)(suo)(suo)定，因此運輸時(shi)不需要回(hui)轉(zhuan)鎖(suo)(suo)(suo)銷。四輪一帶
