支重輪的作用

是挖掘機與推土機底盤四輪一帶中的一種，它(ta)的主要作用是(shi)支撐(cheng)著(zhu)挖(wa)掘機與推土機的重量，讓履帶(dai)沿著(zhu)輪(lun)子前進。      

四(si)(si)輪(lun)(lun)(lun)(lun)驅(qu)動(dong)(dong)（4 Wheel Drive)主(zhu)變速(su)器通過一個輔助變速(su)器將動(dong)(dong)力傳送(song)到前輪(lun)(lun)(lun)(lun)和后(hou)輪(lun)(lun)(lun)(lun). 輔助變速(su)器通常有三(san)檔(dang)選擇； 空檔(dang)，四(si)(si)輪(lun)(lun)(lun)(lun)驅(qu)動(dong)(dong)，四(si)(si)輪(lun)(lun)(lun)(lun)驅(qu)動(dong)(dong)低(di)檔(dang)。空檔(dang)時，四(si)(si)輪(lun)(lun)(lun)(lun)驅(qu)動(dong)(dong)就變成了(le)兩輪(lun)(lun)(lun)(lun)驅(qu)動(dong)(dong)。四(si)(si)輪(lun)(lun)(lun)(lun)驅(qu) 動(dong)(dong)適(shi)合于惡劣的(de)路(lu)面(mian)駕駛，例如，雨雪天和多沙石路(lu)面(mian)。四(si)(si)輪(lun)(lun)(lun)(lun)驅(qu)動(dong)(dong)低(di)檔(dang)則適(shi)合高(gao)難度(du)的(de)越野(ye)駕駛。全輪(lun)(lun)(lun)(lun)驅(qu)動(dong)(dong) (All Wheel Drive)全輪(lun)(lun)(lun)(lun)驅(qu)動(dong)(dong)是四(si)(si)輪(lun)(lun)(lun)(lun)驅(qu)動(dong)(dong)的(de)一種. 它自(zi)動(dong)(dong)將發動(dong)(dong) 機提供(gong)的(de) 扭(niu)矩分送(song)到前輪(lun)(lun)(lun)(lun)和后(hou)輪(lun)(lun)(lun)(lun)，不需(xu)要(yao)手動(dong)(dong)去調(diao)整(zheng)，也沒有低(di)檔(dang)選擇。全輪(lun)(lun)(lun)(lun)驅(qu)動(dong)(dong) 減低(di)了(le)車輪(lun)(lun)(lun)(lun)打(da)滑的(de)程度(du)，改善了(le)駕駛者的(de)控車能力。全輪(lun)(lun)(lun)(lun)驅(qu)動(dong)(dong)通常是一種 正常路(lu)面(mian)駕駛系(xi)統，并不設計用于越野(ye)駕駛。

適時驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)適時驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)介乎全時驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)和分時驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)之間(jian)，驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)模(mo)式(shi)由電(dian)(dian)腦安排，操縱非常(chang)簡單。采(cai)用(yong)這種驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)系統的(de)車(che)輛(liang)時根據(ju)電(dian)(dian)腦來控制并且選擇適合當下情況的(de)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)模(mo)式(shi)。在(zai)正(zheng)常(chang)的(de)路面上車(che)輛(liang)一般會采(cai)用(yong)后輪(lun)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)方式(shi)，而一旦(dan)遇到路面不(bu)(bu)良或(huo)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)輪(lun)打滑(hua)的(de)情況，電(dian)(dian)腦就會自動(dong)(dong)(dong)(dong)(dong)(dong)檢測并立即(ji)將(jiang)發動(dong)(dong)(dong)(dong)(dong)(dong)機輸出扭矩分配給前排的(de)兩(liang)個(ge)車(che)輪(lun)，自然(ran)切(qie)換到四輪(lun)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)狀(zhuang)態，從而免除了(le)駕駛(shi)人的(de)判斷和手(shou)動(dong)(dong)(dong)(dong)(dong)(dong)操作，應用(yong)更加簡單。不(bu)(bu)過以目(mu)前的(de)效果來看，電(dian)(dian)腦比起人腦速度還是(shi)(shi)慢(man)了(le)很多，也就是(shi)(shi)說住往(wang)不(bu)(bu)能及時進行(xing)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)模(mo)式(shi)的(de)切(qie)換，反應較慢(man)。比如(ru)北京現代生產的(de)途勝就是(shi)(shi)采(cai)用(yong)適時四驅(qu)(qu)(qu)(qu)設(she)計(ji)。
