湖南四輪一帶|中特工程(優質商家)|山推四輪一帶：

A、輪(lun)體磨損。出現這種情況的(de)(de)原因是采用的(de)(de)鋼材不(bu)合格或者(zhe)說(shuo)材料熱處(chu)理(li)時(shi)的(de)(de)硬度較低，耐磨性不(bu)足(zu)；B、漏(lou)(lou)油(you)(you)。支重輪(lun)軸(zhou)通過軸(zhou)套一直在(zai)(zai)旋轉，輪(lun)體內要(yao)加(jia)油(you)(you)來潤滑，但如果(guo)說(shuo)密封(feng)圈(quan)不(bu)好的(de)(de)話，很(hen)容易(yi)產生漏(lou)(lou)油(you)(you)的(de)(de)現象，這樣軸(zhou)與軸(zhou)套在(zai)(zai)無潤滑的(de)(de)情況下，很(hen)容易(yi)磨損，造(zao)成產品無法進行(xing)使用。漏(lou)(lou)油(you)(you)原因有分好幾種：1浮動油(you)(you)封(feng)不(bu)合格 2.產品軸(zhou)套圓形度不(bu)夠 3.支軸(zhou)光(guang)澤度不(bu)夠 4.齒輪(lun)油(you)(you)不(bu)達標 5.加(jia)工尺寸公差問題(ti)等等 都會造(zao)成支重輪(lun)漏(lou)(lou)油(you)(you)的(de)(de)情況。

國(guo)內(nei)廠家生產的(de)(de)(de)(de)支(zhi)(zhi)重輪(lun)問(wen)題1.鋼材(cai)標號很(hen)多未達標，熱處理工藝未能很(hen)好(hao)發(fa)揮。2.市場惡性(xing)競爭，產品幾個重要結(jie)構(gou)發(fa)生偷工減(jian)料 如輪(lun)體(ti)(ti)圓徑減(jian)小、支(zhi)(zhi)軸(zhou)變(bian)(bian)細、銅(tong)(tong)(tong)套(tao)長(chang)度縮短等等.輪(lun)體(ti)(ti)圓徑的(de)(de)(de)(de)減(jian)小 變(bian)(bian)成(cheng)輪(lun)子線速度加快(kuai)，軸(zhou)套(tao)承受的(de)(de)(de)(de)摩擦(ca)越(yue)多。支(zhi)(zhi)軸(zhou)變(bian)(bian)細道理也(ye)是(shi)一樣(yang)，同樣(yang)承受撞擊的(de)(de)(de)(de)力度也(ye)會不(bu)夠，照成(cheng)軸(zhou)變(bian)(bian)形或者斷(duan)掉。 銅(tong)(tong)(tong)套(tao)起到摩擦(ca)作用，銅(tong)(tong)(tong)層(ceng)必(bi)須經過滾扎后(hou)才不(bu)易脫(tuo)落，正常(chang)得0.35mm以(yi)上銅(tong)(tong)(tong)層(ceng)才達標，減(jian)少銅(tong)(tong)(tong)套(tao)長(chang)度支(zhi)(zhi)重輪(lun)的(de)(de)(de)(de)意義也(ye)就失去了(le)作用，減(jian)少長(chang)度等同于減(jian)少受力面積。所以(yi)解決產品這幾樣(yang)缺點(dian)，國(guo)內(nei)產品相(xiang)對國(guo)外產品的(de)(de)(de)(de)優(you)勢是(shi)非常(chang)大的(de)(de)(de)(de)。

全(quan)(quan)(quan)輪(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)也分(fen)兩種(zhong)形式(shi)(shi)：一(yi)種(zhong)是(shi)全(quan)(quan)(quan)時全(quan)(quan)(quan)輪(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)，即(ji)全(quan)(quan)(quan)部時間都是(shi)全(quan)(quan)(quan)輪(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)；另一(yi)種(zhong)是(shi)短時全(quan)(quan)(quan)輪(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)，它(ta)可以(yi)切斷某個橋(qiao)的(de)(de)動(dong)(dong)(dong)力(li)(li)，以(yi)減少燃料消耗和磨損，只(zhi)在需要時再使(shi)用全(quan)(quan)(quan)輪(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)。過去只(zhi)有越野車采用4輪(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)，一(yi)般的(de)(de)越野車，變速(su)(su)器(qi)后(hou)(hou)(hou)面(mian)裝有手(shou)動(dong)(dong)(dong)分(fen)離器(qi)，前(qian)(qian)后(hou)(hou)(hou)車軸各(ge)裝一(yi)個稱(cheng)為驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)的(de)(de)部件。變速(su)(su)器(qi)輸出的(de)(de)扭(niu)(niu)矩(ju)(ju)(ju)通(tong)(tong)過分(fen)力(li)(li)器(qi)和傳動(dong)(dong)(dong)軸，分(fen)別傳遞(di)到(dao)(dao)前(qian)(qian)后(hou)(hou)(hou)車軸上(shang)(shang)(shang)(shang)的(de)(de)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)，再通(tong)(tong)過驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)將(jiang)扭(niu)(niu)矩(ju)(ju)(ju)傳遞(di)到(dao)(dao)輪(lun)子上(shang)(shang)(shang)(shang)。現在轎(jiao)車的(de)(de)馬力(li)(li)都比較大，加速(su)(su)時重心(xin)后(hou)(hou)(hou)移(yi)，全(quan)(quan)(quan)車重量就(jiu)會向后(hou)(hou)(hou)軸移(yi)動(dong)(dong)(dong)，造成前(qian)(qian)軸輕飄(piao)。前(qian)(qian)輪(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)的(de)(de)轎(jiao)車即(ji)使(shi)在良好的(de)(de)路(lu)面(mian)上(shang)(shang)(shang)(shang)也會打滑(hua)，4輪(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)就(jiu)可以(yi)防止這種(zhong)現象發生。轎(jiao)車上(shang)(shang)(shang)(shang)的(de)(de)4輪(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)裝置是(shi)常嚙(nie)合(he)式(shi)(shi)，增加了(le)粘性耦合(he)器(qi)，省去了(le)手(shou)動(dong)(dong)(dong)分(fen)力(li)(li)器(qi)，自(zi)動(dong)(dong)(dong)將(jiang)扭(niu)(niu)矩(ju)(ju)(ju)按需分(fen)配在前(qian)(qian)后(hou)(hou)(hou)輪(lun)子上(shang)(shang)(shang)(shang)。在正常路(lu)面(mian)上(shang)(shang)(shang)(shang)，4輪(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)裝置將(jiang)引(yin)擎輸出扭(niu)(niu)矩(ju)(ju)(ju)的(de)(de)92%分(fen)配到(dao)(dao)前(qian)(qian)輪(lun)，8%分(fen)配到(dao)(dao)后(hou)(hou)(hou)輪(lun)；在滑(hua)溜的(de)(de)路(lu)面(mian)上(shang)(shang)(shang)(shang)，將(jiang)至少40%的(de)(de)引(yin)擎機輸出扭(niu)(niu)矩(ju)(ju)(ju)分(fen)配給(gei)后(hou)(hou)(hou)輪(lun)；當前(qian)(qian)輪(lun)開(kai)始打滑(hua)時，前(qian)(qian)、后(hou)(hou)(hou)輪(lun)的(de)(de)轉速(su)(su)差異會使(shi)耦合(he)器(qi)中的(de)(de)粘液立即(ji)變稠并鎖住耦合(he)器(qi)，從而使(shi)傳動(dong)(dong)(dong)軸只(zhi)將(jiang)扭(niu)(niu)矩(ju)(ju)(ju)傳遞(di)至后(hou)(hou)(hou)輪(lun)，待前(qian)(qian)、后(hou)(hou)(hou)輪(lun)的(de)(de)轉速(su)(su)差異消失就(jiu)自(zi)動(dong)(dong)(dong)回(hui)復原有驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)形式(shi)(shi)。
