湖南四輪一帶|中特工程(優質商家)|山推四輪一帶：

A、輪(lun)體(ti)磨損(sun)。出現(xian)(xian)這種情(qing)況的(de)(de)(de)原因(yin)是采用(yong)的(de)(de)(de)鋼材不合格(ge)(ge)或者說(shuo)材料熱處理時的(de)(de)(de)硬(ying)度較低(di)，耐磨性不足；B、漏(lou)油(you)(you)。支重輪(lun)軸(zhou)(zhou)通過(guo)軸(zhou)(zhou)套一直在(zai)旋轉，輪(lun)體(ti)內要加油(you)(you)來(lai)潤(run)滑(hua)，但如果(guo)說(shuo)密封(feng)(feng)圈不好的(de)(de)(de)話，很(hen)容易(yi)產生漏(lou)油(you)(you)的(de)(de)(de)現(xian)(xian)象，這樣軸(zhou)(zhou)與(yu)軸(zhou)(zhou)套在(zai)無(wu)(wu)潤(run)滑(hua)的(de)(de)(de)情(qing)況下(xia)，很(hen)容易(yi)磨損(sun)，造成產品(pin)無(wu)(wu)法進行使用(yong)。漏(lou)油(you)(you)原因(yin)有(you)分好幾種：1浮(fu)動油(you)(you)封(feng)(feng)不合格(ge)(ge) 2.產品(pin)軸(zhou)(zhou)套圓形度不夠 3.支軸(zhou)(zhou)光澤度不夠 4.齒(chi)輪(lun)油(you)(you)不達標 5.加工尺寸公(gong)差問題等等 都會(hui)造成支重輪(lun)漏(lou)油(you)(you)的(de)(de)(de)情(qing)況。

國(guo)內廠家(jia)生(sheng)產(chan)的支(zhi)(zhi)重輪(lun)問題1.鋼材標(biao)號很多(duo)未達標(biao)，熱處理工(gong)藝未能很好(hao)發揮。2.市場惡(e)性(xing)競爭，產(chan)品(pin)幾(ji)個重要結構發生(sheng)偷工(gong)減(jian)料 如輪(lun)體圓(yuan)(yuan)徑減(jian)小(xiao)、支(zhi)(zhi)軸變(bian)(bian)細、銅(tong)(tong)套(tao)長度(du)縮短(duan)等(deng)等(deng).輪(lun)體圓(yuan)(yuan)徑的減(jian)小(xiao) 變(bian)(bian)成輪(lun)子線(xian)速度(du)加快，軸套(tao)承(cheng)(cheng)受(shou)(shou)的摩擦(ca)越多(duo)。支(zhi)(zhi)軸變(bian)(bian)細道理也(ye)是(shi)一樣(yang)，同樣(yang)承(cheng)(cheng)受(shou)(shou)撞(zhuang)擊的力度(du)也(ye)會不夠，照成軸變(bian)(bian)形或者斷(duan)掉。 銅(tong)(tong)套(tao)起到摩擦(ca)作用，銅(tong)(tong)層(ceng)必(bi)須經(jing)過滾扎后(hou)才(cai)不易脫落，正(zheng)常(chang)得0.35mm以(yi)上銅(tong)(tong)層(ceng)才(cai)達標(biao)，減(jian)少銅(tong)(tong)套(tao)長度(du)支(zhi)(zhi)重輪(lun)的意義也(ye)就失去(qu)了作用，減(jian)少長度(du)等(deng)同于減(jian)少受(shou)(shou)力面積。所以(yi)解決產(chan)品(pin)這幾(ji)樣(yang)缺點，國(guo)內產(chan)品(pin)相對國(guo)外產(chan)品(pin)的優勢是(shi)非常(chang)大的。

全(quan)(quan)輪(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)(dong)也分(fen)兩種形式(shi)：一種是(shi)(shi)全(quan)(quan)時全(quan)(quan)輪(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)(dong)，即全(quan)(quan)部時間都是(shi)(shi)全(quan)(quan)輪(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)(dong)；另一種是(shi)(shi)短時全(quan)(quan)輪(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)(dong)，它(ta)可以切斷某個橋的(de)動(dong)(dong)(dong)(dong)(dong)力，以減(jian)少燃(ran)料消耗和磨損，只在(zai)(zai)需(xu)要(yao)時再使(shi)用全(quan)(quan)輪(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)(dong)。過去只有(you)越野車(che)(che)(che)采用4輪(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)(dong)，一般的(de)越野車(che)(che)(che)，變速(su)(su)器(qi)(qi)(qi)(qi)后(hou)(hou)(hou)面裝有(you)手(shou)動(dong)(dong)(dong)(dong)(dong)分(fen)離器(qi)(qi)(qi)(qi)，前(qian)后(hou)(hou)(hou)車(che)(che)(che)軸(zhou)(zhou)各裝一個稱為驅(qu)動(dong)(dong)(dong)(dong)(dong)橋的(de)部件。變速(su)(su)器(qi)(qi)(qi)(qi)輸(shu)出(chu)的(de)扭(niu)(niu)矩(ju)通過分(fen)力器(qi)(qi)(qi)(qi)和傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)，分(fen)別傳(chuan)(chuan)遞到前(qian)后(hou)(hou)(hou)車(che)(che)(che)軸(zhou)(zhou)上(shang)的(de)驅(qu)動(dong)(dong)(dong)(dong)(dong)橋，再通過驅(qu)動(dong)(dong)(dong)(dong)(dong)橋將扭(niu)(niu)矩(ju)傳(chuan)(chuan)遞到輪(lun)(lun)子(zi)上(shang)。現在(zai)(zai)轎車(che)(che)(che)的(de)馬(ma)力都比較大(da)，加速(su)(su)時重心(xin)后(hou)(hou)(hou)移，全(quan)(quan)車(che)(che)(che)重量就(jiu)會向后(hou)(hou)(hou)軸(zhou)(zhou)移動(dong)(dong)(dong)(dong)(dong)，造成前(qian)軸(zhou)(zhou)輕飄(piao)。前(qian)輪(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)(dong)的(de)轎車(che)(che)(che)即使(shi)在(zai)(zai)良好的(de)路(lu)面上(shang)也會打(da)(da)滑(hua)，4輪(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)(dong)就(jiu)可以防(fang)止這(zhe)種現象發生。轎車(che)(che)(che)上(shang)的(de)4輪(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)(dong)裝置是(shi)(shi)常(chang)嚙合(he)式(shi)，增加了粘(zhan)性耦(ou)(ou)合(he)器(qi)(qi)(qi)(qi)，省去了手(shou)動(dong)(dong)(dong)(dong)(dong)分(fen)力器(qi)(qi)(qi)(qi)，自動(dong)(dong)(dong)(dong)(dong)將扭(niu)(niu)矩(ju)按需(xu)分(fen)配(pei)(pei)在(zai)(zai)前(qian)后(hou)(hou)(hou)輪(lun)(lun)子(zi)上(shang)。在(zai)(zai)正常(chang)路(lu)面上(shang)，4輪(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)(dong)裝置將引(yin)擎(qing)輸(shu)出(chu)扭(niu)(niu)矩(ju)的(de)92%分(fen)配(pei)(pei)到前(qian)輪(lun)(lun)，8%分(fen)配(pei)(pei)到后(hou)(hou)(hou)輪(lun)(lun)；在(zai)(zai)滑(hua)溜的(de)路(lu)面上(shang)，將至少40%的(de)引(yin)擎(qing)機(ji)輸(shu)出(chu)扭(niu)(niu)矩(ju)分(fen)配(pei)(pei)給后(hou)(hou)(hou)輪(lun)(lun)；當前(qian)輪(lun)(lun)開始打(da)(da)滑(hua)時，前(qian)、后(hou)(hou)(hou)輪(lun)(lun)的(de)轉(zhuan)速(su)(su)差異會使(shi)耦(ou)(ou)合(he)器(qi)(qi)(qi)(qi)中的(de)粘(zhan)液立即變稠并鎖住(zhu)耦(ou)(ou)合(he)器(qi)(qi)(qi)(qi)，從而使(shi)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)只將扭(niu)(niu)矩(ju)傳(chuan)(chuan)遞至后(hou)(hou)(hou)輪(lun)(lun)，待前(qian)、后(hou)(hou)(hou)輪(lun)(lun)的(de)轉(zhuan)速(su)(su)差異消失就(jiu)自動(dong)(dong)(dong)(dong)(dong)回復原有(you)驅(qu)動(dong)(dong)(dong)(dong)(dong)形式(shi)。
