阜康四輪一帶-中特工程-求購四輪一帶：

全(quan)(quan)(quan)(quan)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)也分(fen)兩種(zhong)(zhong)形(xing)(xing)式(shi)：一(yi)種(zhong)(zhong)是(shi)全(quan)(quan)(quan)(quan)時全(quan)(quan)(quan)(quan)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)，即全(quan)(quan)(quan)(quan)部時間都(dou)是(shi)全(quan)(quan)(quan)(quan)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)；另一(yi)種(zhong)(zhong)是(shi)短時全(quan)(quan)(quan)(quan)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)，它可以切(qie)斷某個橋(qiao)的動(dong)(dong)(dong)力(li)，以減(jian)少(shao)燃料消耗(hao)和(he)磨損，只在(zai)需要時再使用全(quan)(quan)(quan)(quan)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)。過去只有越野車(che)采用4輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)，一(yi)般的越野車(che)，變(bian)速(su)器(qi)(qi)后(hou)(hou)(hou)(hou)(hou)(hou)面裝有手動(dong)(dong)(dong)分(fen)離器(qi)(qi)，前(qian)后(hou)(hou)(hou)(hou)(hou)(hou)車(che)軸各(ge)裝一(yi)個稱為驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)的部件。變(bian)速(su)器(qi)(qi)輸出的扭(niu)矩(ju)通(tong)過分(fen)力(li)器(qi)(qi)和(he)傳動(dong)(dong)(dong)軸，分(fen)別(bie)傳遞(di)到(dao)前(qian)后(hou)(hou)(hou)(hou)(hou)(hou)車(che)軸上(shang)的驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)，再通(tong)過驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)將(jiang)(jiang)扭(niu)矩(ju)傳遞(di)到(dao)輪(lun)子(zi)上(shang)。現在(zai)轎車(che)的馬力(li)都(dou)比較大(da)，加速(su)時后(hou)(hou)(hou)(hou)(hou)(hou)移，全(quan)(quan)(quan)(quan)車(che)重量就會(hui)向后(hou)(hou)(hou)(hou)(hou)(hou)軸移動(dong)(dong)(dong)，造成前(qian)軸輕(qing)飄(piao)。前(qian)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)的轎車(che)即使在(zai)良好的路面上(shang)也會(hui)打(da)滑，4輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)就可以防止這種(zhong)(zhong)現象發(fa)生。轎車(che)上(shang)的4輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)裝置(zhi)是(shi)常(chang)嚙合(he)式(shi)，增加了(le)粘性耦合(he)器(qi)(qi)，省去了(le)手動(dong)(dong)(dong)分(fen)力(li)器(qi)(qi)，自(zi)動(dong)(dong)(dong)將(jiang)(jiang)扭(niu)矩(ju)按需分(fen)配在(zai)前(qian)后(hou)(hou)(hou)(hou)(hou)(hou)輪(lun)子(zi)上(shang)。在(zai)正常(chang)路面上(shang)，4輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)裝置(zhi)將(jiang)(jiang)引(yin)(yin)擎輸出扭(niu)矩(ju)的92%分(fen)配到(dao)前(qian)輪(lun)，8%分(fen)配到(dao)后(hou)(hou)(hou)(hou)(hou)(hou)輪(lun)；在(zai)滑溜的路面上(shang)，將(jiang)(jiang)至少(shao)40%的引(yin)(yin)擎機輸出扭(niu)矩(ju)分(fen)配給后(hou)(hou)(hou)(hou)(hou)(hou)輪(lun)；當前(qian)輪(lun)開始打(da)滑時，前(qian)、后(hou)(hou)(hou)(hou)(hou)(hou)輪(lun)的轉(zhuan)速(su)差異會(hui)使耦合(he)器(qi)(qi)中(zhong)的粘液立即變(bian)稠并鎖住耦合(he)器(qi)(qi)，從而使傳動(dong)(dong)(dong)軸只將(jiang)(jiang)扭(niu)矩(ju)傳遞(di)至后(hou)(hou)(hou)(hou)(hou)(hou)輪(lun)，待前(qian)、后(hou)(hou)(hou)(hou)(hou)(hou)輪(lun)的轉(zhuan)速(su)差異消失就自(zi)動(dong)(dong)(dong)回復原有驅(qu)(qu)(qu)動(dong)(dong)(dong)形(xing)(xing)式(shi)。

適(shi)時(shi)(shi)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)適(shi)時(shi)(shi)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)介乎全時(shi)(shi)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)和分(fen)時(shi)(shi)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)之間，驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)模(mo)式(shi)由電腦(nao)(nao)安排(pai)，操縱非常簡單。采用(yong)(yong)這種驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)系統的(de)(de)(de)車輛(liang)時(shi)(shi)根據電腦(nao)(nao)來(lai)控制并且(qie)選擇適(shi)合當下情況的(de)(de)(de)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)模(mo)式(shi)。在正常的(de)(de)(de)路面上車輛(liang)一(yi)般會采用(yong)(yong)后輪驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)的(de)(de)(de)方式(shi)，而(er)(er)一(yi)旦遇(yu)到(dao)路面不(bu)良或驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)輪打(da)滑(hua)的(de)(de)(de)情況，電腦(nao)(nao)就會自動(dong)(dong)(dong)(dong)檢測并立即(ji)將發動(dong)(dong)(dong)(dong)機輸出扭矩分(fen)配給前(qian)排(pai)的(de)(de)(de)兩(liang)個車輪，自然切換(huan)到(dao)四輪驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)狀(zhuang)態，從而(er)(er)免(mian)除了駕駛人的(de)(de)(de)判(pan)斷和手(shou)動(dong)(dong)(dong)(dong)操作，應(ying)用(yong)(yong)更加簡單。不(bu)過以目(mu)前(qian)的(de)(de)(de)效(xiao)果來(lai)看(kan)，電腦(nao)(nao)比(bi)(bi)起人腦(nao)(nao)速度還是慢了很多，也就是說住往不(bu)能及時(shi)(shi)進行驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)模(mo)式(shi)的(de)(de)(de)切換(huan)，反應(ying)較(jiao)慢。比(bi)(bi)如北京現代(dai)生產的(de)(de)(de)途勝(sheng)就是采用(yong)(yong)適(shi)時(shi)(shi)四驅(qu)(qu)(qu)(qu)設(she)計。
