適(shi)時(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)適(shi)時(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)介乎全(quan)時(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)分時(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)之間，驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)模(mo)式(shi)由電(dian)(dian)(dian)腦安排，操縱非常(chang)簡(jian)單。采用(yong)這種(zhong)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)系統的(de)(de)(de)(de)(de)車輛時(shi)根據電(dian)(dian)(dian)腦來控制并且選擇(ze)適(shi)合當(dang)下情況的(de)(de)(de)(de)(de)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)模(mo)式(shi)。在正(zheng)常(chang)的(de)(de)(de)(de)(de)路面上車輛一(yi)般會(hui)采用(yong)后(hou)輪驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)(de)(de)方式(shi)，而(er)一(yi)旦遇(yu)到(dao)路面不良或驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)輪打(da)滑的(de)(de)(de)(de)(de)情況，電(dian)(dian)(dian)腦就會(hui)自動(dong)(dong)(dong)(dong)(dong)(dong)檢測(ce)并立(li)即(ji)將發動(dong)(dong)(dong)(dong)(dong)(dong)機輸出扭(niu)矩分配給前(qian)排的(de)(de)(de)(de)(de)兩(liang)個車輪，自然切換到(dao)四(si)輪驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)狀態(tai)，從而(er)免除(chu)了駕駛人的(de)(de)(de)(de)(de)判斷和(he)手動(dong)(dong)(dong)(dong)(dong)(dong)操作，應用(yong)更加簡(jian)單。不過(guo)以(yi)目前(qian)的(de)(de)(de)(de)(de)效果來看，電(dian)(dian)(dian)腦比(bi)起人腦速度還是慢了很多，也就是說住往不能及時(shi)進行驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)模(mo)式(shi)的(de)(de)(de)(de)(de)切換，反應較慢。比(bi)如北京現(xian)代生產的(de)(de)(de)(de)(de)途勝就是采用(yong)適(shi)時(shi)四(si)驅(qu)(qu)(qu)設(she)計。

支重輪的主要結構：

輪(lun)體、支(zhi)(zhi)重輪(lun)軸、軸套、密封圈(quan)、端蓋等(deng)相關部件構(gou)成。支(zhi)(zhi)重輪(lun)可分(fen)為(wei)單邊支(zhi)(zhi)重輪(lun)與(yu)雙邊支(zhi)(zhi)重輪(lun)；挖掘機(ji)用(yong)支(zhi)(zhi)重輪(lun)與(yu)推(tui)土(tu)機(ji)用(yong)支(zhi)(zhi)重輪(lun)，挖掘機(ji)用(yong)支(zhi)(zhi)重輪(lun)一般是黑色(se)(se)油漆，推(tui)土(tu)機(ji)支(zhi)(zhi)重輪(lun)一般是黃(huang)色(se)(se)油漆。    

支重(zhong)輪容易出現在問題

A、輪體磨損(sun)。出現(xian)這(zhe)種情況的原因是采用的鋼材(cai)不合(he)格或者說材(cai)料熱(re)處(chu)理時的硬度較低，耐(nai)磨性不足；

B、漏(lou)油。支重輪軸(zhou)通過軸(zhou)套一(yi)直在(zai)旋轉，輪體內(nei)要加油來潤滑，但如果說密(mi)封(feng)圈不好的(de)話，很容易產(chan)生漏(lou)油的(de)現象，這(zhe)樣軸(zhou)與(yu)軸(zhou)套在(zai)無潤滑的(de)情況下(xia)，很容易磨損，造成產(chan)品無法進行使用(yong)。因(yin)此(ci)，

支重(zhong)輪密封(feng)的好壞(huai)是作為衡量生產(chan)(chan)公(gong)司產(chan)(chan)品質量的一(yi)個很重(zhong)要的標(biao)準。
