遼寧履帶驅動輪,中特工程(優質商家),挖掘機履帶驅動輪：

后(hou)輪(lun)驅(qu)動（RWD）：豪華轎車(che)通常采用后(hou)驅(qu)，重量分配接(jie)近(jin)于50∶50，提供了(le)更平穩(wen)的駕(jia)駛(shi)。RWD與FWD驅(qu)動情況正相反，操控性能有所提高(gao)。當加(jia)速時車(che)身重心向后(hou)轉移，這正是你所希望的，因(yin)為后(hou)輪(lun)主(zhu)管牽(qian)引力，前(qian)輪(lun)主(zhu)管汽車(che)方向。你還(huan)可以在(zai)(zai)彎道(dao)加(jia)速。這并不是說(shuo)RWD在(zai)(zai)結構上就(jiu)好，它(ta)也存(cun)在(zai)(zai)缺陷，如從(cong)前(qian)到后(hou)的傳動軸（使(shi)車(che)內地板從(cong)前(qian)到后(hou)隆(long)起），還(huan)有一(yi)個(ge)很大的差速器在(zai)(zai)后(hou)部，增加(jia)了(le)重量和成本，它(ta)同樣(yang)不適應(ying)全天候(hou)駕(jia)駛(shi)。

汽車的(de)(de)(de)(de)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)形(xing)式一(yi)般有以下幾(ji)種：前置(zhi)后驅(qu)(qu)(qu)(qu)(FR)、前置(zhi)前驅(qu)(qu)(qu)(qu)(FF)、后置(zhi)后驅(qu)(qu)(qu)(qu)(RR)、中置(zhi)后驅(qu)(qu)(qu)(qu)(MR)、四(si)輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)。所謂驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)形(xing)式，是(shi)(shi)指(zhi)發動(dong)(dong)(dong)(dong)(dong)機(ji)的(de)(de)(de)(de)布(bu)(bu)置(zhi)方式及驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)輪(lun)(lun)(lun)(lun)(lun)的(de)(de)(de)(de)數量(liang)、位(wei)置(zhi)的(de)(de)(de)(de)形(xing)式。國(guo)內外大多(duo)數貨車(含皮卡)、部分(fen)(fen)轎(jiao)(jiao)車(尤其是(shi)(shi)高級轎(jiao)(jiao)車)和部分(fen)(fen)客車都采用(yong)前置(zhi)后驅(qu)(qu)(qu)(qu)的(de)(de)(de)(de)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)型式，但采用(yong)該(gai)型式的(de)(de)(de)(de)小型車很少。所謂全(quan)輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)，又稱四(si)輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)，是(shi)(shi)指(zhi)汽車前后輪(lun)(lun)(lun)(lun)(lun)都有動(dong)(dong)(dong)(dong)(dong)力(li)。一(yi)般用(yong)4X4或4WD來(lai)表示，如果你看見一(yi)輛車上標(biao)有上述字樣，那(nei)就表示該(gai)車輛擁有4輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)(de)功(gong)能(neng)。這種總布(bu)(bu)置(zhi)形(xing)式，由(you)于全(quan)部車輪(lun)(lun)(lun)(lun)(lun)都是(shi)(shi)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)輪(lun)(lun)(lun)(lun)(lun)，充分(fen)(fen)利用(yong)了汽車的(de)(de)(de)(de)全(quan)部附著質量(liang)，因此汽車有較大的(de)(de)(de)(de)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)力(li)和克服障礙、防(fang)止打滑的(de)(de)(de)(de)能(neng)力(li)。所以，越野(ye)汽車一(yi)般都采用(yong)這種總布(bu)(bu)置(zhi)形(xing)式。而且，由(you)于全(quan)輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)(de)汽車有較大的(de)(de)(de)(de)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)力(li)，加速性好，20世紀80年代以來(lai)一(yi)些轎(jiao)(jiao)車和旅行轎(jiao)(jiao)車也紛紛采用(yong)全(quan)輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)，成為(wei)所謂的(de)(de)(de)(de)“多(duo)用(yong)途運(yun)動(dong)(dong)(dong)(dong)(dong)車（SUV）”，受(shou)到不少美(mei)國(guo)年輕人的(de)(de)(de)(de)喜愛，形(xing)成了'4WD'熱潮。但是(shi)(shi)，全(quan)輪(lun)(lun)(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)(de)結構復雜，成本高，在好路上行駛時(shi)燃料消耗大，輪(lun)(lun)(lun)(lun)(lun)胎和機(ji)件的(de)(de)(de)(de)磨(mo)損大。

適(shi)時驅(qu)(qu)(qu)動(dong)(dong)(dong)適(shi)時驅(qu)(qu)(qu)動(dong)(dong)(dong)介乎(hu)全時驅(qu)(qu)(qu)動(dong)(dong)(dong)和分時驅(qu)(qu)(qu)動(dong)(dong)(dong)之間，驅(qu)(qu)(qu)動(dong)(dong)(dong)模(mo)式(shi)由電腦安排(pai)(pai)，操(cao)縱非(fei)常簡單。采用(yong)這種驅(qu)(qu)(qu)動(dong)(dong)(dong)系(xi)統(tong)的(de)(de)車(che)輛時根據電腦來(lai)控(kong)制并(bing)且選擇適(shi)合當(dang)下情(qing)況(kuang)的(de)(de)驅(qu)(qu)(qu)動(dong)(dong)(dong)模(mo)式(shi)。在正常的(de)(de)路面(mian)上車(che)輛一般會(hui)采用(yong)后輪驅(qu)(qu)(qu)動(dong)(dong)(dong)的(de)(de)方(fang)式(shi)，而(er)一旦遇到(dao)路面(mian)不良或(huo)驅(qu)(qu)(qu)動(dong)(dong)(dong)輪打滑的(de)(de)情(qing)況(kuang)，電腦就會(hui)自動(dong)(dong)(dong)檢測并(bing)立即將發動(dong)(dong)(dong)機輸出扭矩(ju)分配給前排(pai)(pai)的(de)(de)兩個車(che)輪，自然切(qie)換到(dao)四輪驅(qu)(qu)(qu)動(dong)(dong)(dong)狀態，從而(er)免(mian)除(chu)了駕駛(shi)人的(de)(de)判斷(duan)和手動(dong)(dong)(dong)操(cao)作，應用(yong)更(geng)加簡單。不過以目前的(de)(de)效果(guo)來(lai)看，電腦比起人腦速度還是慢了很多，也就是說住往不能及(ji)時進行驅(qu)(qu)(qu)動(dong)(dong)(dong)模(mo)式(shi)的(de)(de)切(qie)換，反應較慢。比如北京現代生產的(de)(de)途勝(sheng)就是采用(yong)適(shi)時四驅(qu)(qu)(qu)設計。
