四輪一帶-中特重工廠家-山推四輪一帶：

全(quan)(quan)輪(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)也(ye)分(fen)(fen)(fen)兩種(zhong)形式：一種(zhong)是(shi)全(quan)(quan)時(shi)全(quan)(quan)輪(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，即全(quan)(quan)部時(shi)間都是(shi)全(quan)(quan)輪(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)；另一種(zhong)是(shi)短時(shi)全(quan)(quan)輪(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，它可以(yi)(yi)切(qie)斷某個(ge)橋的(de)(de)(de)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)力，以(yi)(yi)減少燃料消耗和(he)磨(mo)損(sun)，只(zhi)(zhi)在(zai)(zai)(zai)需要時(shi)再使用全(quan)(quan)輪(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)。過去只(zhi)(zhi)有越野(ye)車(che)采用4輪(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，一般的(de)(de)(de)越野(ye)車(che)，變(bian)速(su)器(qi)(qi)(qi)后(hou)(hou)(hou)面(mian)(mian)裝(zhuang)(zhuang)有手(shou)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)分(fen)(fen)(fen)離器(qi)(qi)(qi)，前(qian)后(hou)(hou)(hou)車(che)軸(zhou)(zhou)(zhou)各裝(zhuang)(zhuang)一個(ge)稱(cheng)為(wei)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)橋的(de)(de)(de)部件。變(bian)速(su)器(qi)(qi)(qi)輸出的(de)(de)(de)扭(niu)矩(ju)(ju)通過分(fen)(fen)(fen)力器(qi)(qi)(qi)和(he)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)，分(fen)(fen)(fen)別傳(chuan)遞(di)到前(qian)后(hou)(hou)(hou)車(che)軸(zhou)(zhou)(zhou)上(shang)(shang)的(de)(de)(de)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)橋，再通過驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)橋將(jiang)扭(niu)矩(ju)(ju)傳(chuan)遞(di)到輪(lun)(lun)(lun)子上(shang)(shang)。現在(zai)(zai)(zai)轎車(che)的(de)(de)(de)馬力都比較大，加(jia)速(su)時(shi)后(hou)(hou)(hou)移(yi)，全(quan)(quan)車(che)重量就會(hui)向后(hou)(hou)(hou)軸(zhou)(zhou)(zhou)移(yi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，造成前(qian)軸(zhou)(zhou)(zhou)輕飄。前(qian)輪(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)轎車(che)即使在(zai)(zai)(zai)良好的(de)(de)(de)路面(mian)(mian)上(shang)(shang)也(ye)會(hui)打(da)滑(hua)(hua)，4輪(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)就可以(yi)(yi)防止這種(zhong)現象發生。轎車(che)上(shang)(shang)的(de)(de)(de)4輪(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)裝(zhuang)(zhuang)置是(shi)常嚙合(he)式，增加(jia)了粘性耦合(he)器(qi)(qi)(qi)，省去了手(shou)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)分(fen)(fen)(fen)力器(qi)(qi)(qi)，自動(dong)(dong)(dong)(dong)(dong)(dong)(dong)將(jiang)扭(niu)矩(ju)(ju)按需分(fen)(fen)(fen)配(pei)在(zai)(zai)(zai)前(qian)后(hou)(hou)(hou)輪(lun)(lun)(lun)子上(shang)(shang)。在(zai)(zai)(zai)正常路面(mian)(mian)上(shang)(shang)，4輪(lun)(lun)(lun)驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)裝(zhuang)(zhuang)置將(jiang)引擎輸出扭(niu)矩(ju)(ju)的(de)(de)(de)92%分(fen)(fen)(fen)配(pei)到前(qian)輪(lun)(lun)(lun)，8%分(fen)(fen)(fen)配(pei)到后(hou)(hou)(hou)輪(lun)(lun)(lun)；在(zai)(zai)(zai)滑(hua)(hua)溜(liu)的(de)(de)(de)路面(mian)(mian)上(shang)(shang)，將(jiang)至(zhi)少40%的(de)(de)(de)引擎機(ji)輸出扭(niu)矩(ju)(ju)分(fen)(fen)(fen)配(pei)給后(hou)(hou)(hou)輪(lun)(lun)(lun)；當(dang)前(qian)輪(lun)(lun)(lun)開始打(da)滑(hua)(hua)時(shi)，前(qian)、后(hou)(hou)(hou)輪(lun)(lun)(lun)的(de)(de)(de)轉(zhuan)速(su)差(cha)異會(hui)使耦合(he)器(qi)(qi)(qi)中(zhong)的(de)(de)(de)粘液立即變(bian)稠(chou)并鎖住耦合(he)器(qi)(qi)(qi)，從而使傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)只(zhi)(zhi)將(jiang)扭(niu)矩(ju)(ju)傳(chuan)遞(di)至(zhi)后(hou)(hou)(hou)輪(lun)(lun)(lun)，待前(qian)、后(hou)(hou)(hou)輪(lun)(lun)(lun)的(de)(de)(de)轉(zhuan)速(su)差(cha)異消失(shi)就自動(dong)(dong)(dong)(dong)(dong)(dong)(dong)回復原有驅(qu)(qu)(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)形式。

A、輪體磨(mo)(mo)損。出現這(zhe)種情況(kuang)(kuang)的(de)(de)原因(yin)是(shi)采用的(de)(de)鋼材(cai)不合格(ge)或者說材(cai)料(liao)熱(re)處理時的(de)(de)硬度較低，耐磨(mo)(mo)性不足；B、漏油(you)。支重(zhong)輪軸(zhou)通過軸(zhou)套(tao)一直(zhi)在旋轉，輪體內要(yao)加油(you)來潤滑(hua)，但(dan)如果(guo)說密封圈(quan)不好的(de)(de)話(hua)，很容(rong)易產生漏油(you)的(de)(de)現象，這(zhe)樣軸(zhou)與軸(zhou)套(tao)在無潤滑(hua)的(de)(de)情況(kuang)(kuang)下，很容(rong)易磨(mo)(mo)損，造成產品無法進行使用。漏油(you)原因(yin)有分好幾種：1浮動油(you)封不合格(ge) 2.產品軸(zhou)套(tao)圓形度不夠(gou) 3.支軸(zhou)光澤度不夠(gou) 4.齒輪油(you)不達標 5.加工尺(chi)寸公差問(wen)題等等 都會造成支重(zhong)輪漏油(you)的(de)(de)情況(kuang)(kuang)。

國內廠家生產(chan)的支重輪問題1.鋼材標(biao)(biao)號很(hen)多(duo)(duo)未(wei)達標(biao)(biao)，熱處(chu)理工藝未(wei)能(neng)很(hen)好發揮。2.市場競爭，產(chan)品(pin)幾(ji)個重要(yao)結構(gou)發生偷工減(jian)料 如輪體圓徑減(jian)小、支軸(zhou)變細(xi)(xi)、銅套(tao)長度(du)(du)縮短等(deng)等(deng).輪體圓徑的減(jian)小 變成(cheng)輪子線速度(du)(du)加快(kuai)，軸(zhou)套(tao)承(cheng)受(shou)的摩擦越多(duo)(duo)。支軸(zhou)變細(xi)(xi)道理也是(shi)一(yi)樣，同(tong)(tong)樣承(cheng)受(shou)撞擊的力(li)度(du)(du)也會(hui)不夠，照成(cheng)軸(zhou)變形或者斷掉。 銅套(tao)起到摩擦作(zuo)用，銅層(ceng)必須經過(guo)滾(gun)扎后才(cai)不易(yi)脫落(luo)，正常得(de)0.35mm以(yi)上銅層(ceng)才(cai)達標(biao)(biao)，減(jian)少銅套(tao)長度(du)(du)支重輪的意義(yi)也就失(shi)去(qu)了作(zuo)用，減(jian)少長度(du)(du)等(deng)同(tong)(tong)于(yu)減(jian)少受(shou)力(li)面(mian)積(ji)。所以(yi)解(jie)決產(chan)品(pin)這幾(ji)樣缺點(dian)，國內產(chan)品(pin)相對國外產(chan)品(pin)的優勢是(shi)非(fei)常大的。
