廣西四輪一帶-中特重工(推薦商家)-驅動輪四輪一帶：

適時驅(qu)(qu)動(dong)(dong)適時驅(qu)(qu)動(dong)(dong)介乎(hu)全時驅(qu)(qu)動(dong)(dong)和分時驅(qu)(qu)動(dong)(dong)之(zhi)間(jian)，驅(qu)(qu)動(dong)(dong)模(mo)式(shi)(shi)由電腦(nao)(nao)安(an)排，操(cao)縱非常簡單。采用這(zhe)種驅(qu)(qu)動(dong)(dong)系統的(de)(de)車(che)輛(liang)時根(gen)據電腦(nao)(nao)來(lai)控(kong)制并且選擇適合當下情況的(de)(de)驅(qu)(qu)動(dong)(dong)模(mo)式(shi)(shi)。在(zai)正常的(de)(de)路面上車(che)輛(liang)一般(ban)會采用后輪驅(qu)(qu)動(dong)(dong)的(de)(de)方(fang)式(shi)(shi)，而(er)一旦遇(yu)到路面不(bu)良或驅(qu)(qu)動(dong)(dong)輪打滑的(de)(de)情況，電腦(nao)(nao)就會自(zi)動(dong)(dong)檢測(ce)并立即將發動(dong)(dong)機輸出(chu)扭(niu)矩分配給(gei)前排的(de)(de)兩個車(che)輪，自(zi)然切(qie)換到四(si)輪驅(qu)(qu)動(dong)(dong)狀態，從而(er)免除了駕駛人(ren)的(de)(de)判斷和手(shou)動(dong)(dong)操(cao)作，應用更(geng)加簡單。不(bu)過(guo)以目前的(de)(de)效果來(lai)看，電腦(nao)(nao)比(bi)(bi)起人(ren)腦(nao)(nao)速度還是(shi)慢(man)了很多，也就是(shi)說住往不(bu)能及時進行驅(qu)(qu)動(dong)(dong)模(mo)式(shi)(shi)的(de)(de)切(qie)換，反應較慢(man)。比(bi)(bi)如北京現代(dai)生(sheng)產的(de)(de)途勝就是(shi)采用適時四(si)驅(qu)(qu)設(she)計(ji)。

四(si)(si)輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)（4 Wheel Drive)主變(bian)速器通(tong)過一個(ge)輔助(zhu)變(bian)速器將動(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)傳送(song)到(dao)前(qian)(qian)輪(lun)(lun)和(he)后輪(lun)(lun). 輔助(zhu)變(bian)速器通(tong)常有三(san)檔選擇(ze)； 空(kong)檔，四(si)(si)輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，四(si)(si)輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)低檔。空(kong)檔時，四(si)(si)輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)就變(bian)成了(le)兩輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)。四(si)(si)輪(lun)(lun)驅(qu)(qu) 動(dong)(dong)(dong)(dong)(dong)(dong)(dong)適合于惡劣的(de)路(lu)(lu)面駕(jia)(jia)駛(shi)，例如，雨雪(xue)天和(he)多沙(sha)石路(lu)(lu)面。四(si)(si)輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)低檔則適合高難度(du)的(de)越(yue)野(ye)駕(jia)(jia)駛(shi)。全(quan)(quan)輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong) (All Wheel Drive)全(quan)(quan)輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)是四(si)(si)輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)一種. 它(ta)自動(dong)(dong)(dong)(dong)(dong)(dong)(dong)將發(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong) 機(ji)提供(gong)的(de) 扭(niu)矩分送(song)到(dao)前(qian)(qian)輪(lun)(lun)和(he)后輪(lun)(lun)，不(bu)(bu)需要(yao)手動(dong)(dong)(dong)(dong)(dong)(dong)(dong)去調(diao)整，也沒(mei)有低檔選擇(ze)。全(quan)(quan)輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong) 減低了(le)車輪(lun)(lun)打滑的(de)程(cheng)度(du)，改(gai)善了(le)駕(jia)(jia)駛(shi)者的(de)控(kong)車能(neng)力(li)。全(quan)(quan)輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)通(tong)常是一種 正常路(lu)(lu)面駕(jia)(jia)駛(shi)系統(tong)，并不(bu)(bu)設計用于越(yue)野(ye)駕(jia)(jia)駛(shi)。
