焦作四輪一帶-中特重工(在線咨詢)-四輪一帶工程機械：

轎(jiao)車(che)AWD系統實際上(shang)是(shi)驅(qu)(qu)(qu)動力分配(pei)控制方式(shi)的(de)(de)四輪(lun)(lun)驅(qu)(qu)(qu)動，它利用(yong)電腦和(he)各種(zhong)不(bu)(bu)斷(duan)改進(jin)的(de)(de)傳(chuan)感(gan)器，不(bu)(bu)斷(duan)判斷(duan)輪(lun)(lun)胎(tai)對(dui)地 面的(de)(de)動態附著力和(he)司機的(de)(de)駕駛(shi)(shi)意圖，積極(ji)控制汽(qi)車(che)差(cha)速(su)器的(de)(de)差(cha)動狀態，平(ping)衡各輪(lun)(lun)的(de)(de)驅(qu)(qu)(qu)動力，優化汽(qi)車(che)的(de)(de)各項性能。典型的(de)(de)轎(jiao)車(che)AWD系統主要由前(qian)后(hou)(hou)輪(lun)(lun)驅(qu)(qu)(qu)動裝置、傳(chuan)感(gan)器、電控單元、分動器和(he)液壓(ya)裝置等組成。控制系統的(de)(de)控制原(yuan)理，在前(qian)后(hou)(hou)輪(lun)(lun)之問布置一個濕式(shi)多片離合器，在汽(qi)車(che)行(xing)(xing)駛(shi)(shi)過程中，使(shi)用(yong)電腦控制液壓(ya)系統的(de)(de)油壓(ya)，適應汽(qi)車(che)的(de)(de)行(xing)(xing) 駛(shi)(shi)狀態將驅(qu)(qu)(qu)動扭(niu)矩分配(pei)到前(qian)后(hou)(hou)車(che)輪(lun)(lun)上(shang)去。

四(si)輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)（4 Wheel Drive)主變(bian)(bian)(bian)速器通(tong)過一(yi)(yi)個輔助變(bian)(bian)(bian)速器將動(dong)(dong)(dong)(dong)(dong)(dong)力傳送到(dao)前輪(lun)(lun)(lun)和(he)后(hou)輪(lun)(lun)(lun). 輔助變(bian)(bian)(bian)速器通(tong)常有三(san)檔(dang)選擇； 空(kong)檔(dang)，四(si)輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)，四(si)輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)低(di)(di)檔(dang)。空(kong)檔(dang)時，四(si)輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)就變(bian)(bian)(bian)成了兩輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)。四(si)輪(lun)(lun)(lun)驅(qu)(qu) 動(dong)(dong)(dong)(dong)(dong)(dong)適合于(yu)惡劣的(de)(de)路(lu)面(mian)駕駛，例(li)如，雨雪天和(he)多沙(sha)石路(lu)面(mian)。四(si)輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)低(di)(di)檔(dang)則適合高(gao)難度的(de)(de)越野駕駛。全(quan)(quan)(quan)輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong) (All Wheel Drive)全(quan)(quan)(quan)輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)是四(si)輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)一(yi)(yi)種(zhong). 它(ta)自動(dong)(dong)(dong)(dong)(dong)(dong)將發動(dong)(dong)(dong)(dong)(dong)(dong) 機(ji)提供的(de)(de) 扭矩分(fen)送到(dao)前輪(lun)(lun)(lun)和(he)后(hou)輪(lun)(lun)(lun)，不需要(yao)手動(dong)(dong)(dong)(dong)(dong)(dong)去調整，也沒有低(di)(di)檔(dang)選擇。全(quan)(quan)(quan)輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong) 減低(di)(di)了車輪(lun)(lun)(lun)打滑(hua)的(de)(de)程度，改善了駕駛者的(de)(de)控車能力。全(quan)(quan)(quan)輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)通(tong)常是一(yi)(yi)種(zhong) 正(zheng)常路(lu)面(mian)駕駛系統(tong)，并(bing)不設計用于(yu)越野駕駛。

A、輪(lun)(lun)體(ti)磨(mo)損(sun)。出現這種情況的原因是(shi)采用的鋼材不合格或者說材料熱處理時(shi)的硬度較(jiao)低，耐磨(mo)性不足；B、漏(lou)油(you)。支重(zhong)輪(lun)(lun)軸(zhou)(zhou)通過(guo)軸(zhou)(zhou)套一直在(zai)旋轉，輪(lun)(lun)體(ti)內要加(jia)(jia)油(you)來潤滑(hua)，但如果說密封圈(quan)不好(hao)的話，很(hen)容易(yi)產生漏(lou)油(you)的現象，這樣軸(zhou)(zhou)與軸(zhou)(zhou)套在(zai)無潤滑(hua)的情況下，很(hen)容易(yi)磨(mo)損(sun)，造(zao)成產品無法(fa)進行使用。漏(lou)油(you)原因有分好(hao)幾種：1浮動油(you)封不合格 2.產品軸(zhou)(zhou)套圓(yuan)形(xing)度不夠 3.支軸(zhou)(zhou)光澤度不夠 4.齒(chi)輪(lun)(lun)油(you)不達(da)標 5.加(jia)(jia)工(gong)尺寸公差問(wen)題等(deng)等(deng) 都會(hui)造(zao)成支重(zhong)輪(lun)(lun)漏(lou)油(you)的情況。

國(guo)內(nei)(nei)廠家生產(chan)的(de)(de)(de)支重輪(lun)問題1.鋼材標號很多未達標，熱處理工(gong)藝(yi)未能很好發揮。2.市場競爭，產(chan)品(pin)幾(ji)個(ge)重要結(jie)構發生偷工(gong)減(jian)(jian)(jian)料 如輪(lun)體(ti)圓徑(jing)減(jian)(jian)(jian)小(xiao)(xiao)、支軸(zhou)變(bian)細、銅套(tao)長(chang)度縮短等(deng)(deng)等(deng)(deng).輪(lun)體(ti)圓徑(jing)的(de)(de)(de)減(jian)(jian)(jian)小(xiao)(xiao) 變(bian)成輪(lun)子(zi)線速度加快，軸(zhou)套(tao)承(cheng)(cheng)受(shou)的(de)(de)(de)摩擦越(yue)多。支軸(zhou)變(bian)細道理也是一(yi)樣，同樣承(cheng)(cheng)受(shou)撞擊的(de)(de)(de)力度也會(hui)不夠，照成軸(zhou)變(bian)形或(huo)者斷掉。 銅套(tao)起(qi)到(dao)摩擦作(zuo)用，銅層必須經過滾扎(zha)后才不易脫(tuo)落，正常得0.35mm以上銅層才達標，減(jian)(jian)(jian)少(shao)銅套(tao)長(chang)度支重輪(lun)的(de)(de)(de)意義也就失去了作(zuo)用，減(jian)(jian)(jian)少(shao)長(chang)度等(deng)(deng)同于減(jian)(jian)(jian)少(shao)受(shou)力面(mian)積。所(suo)以解決產(chan)品(pin)這幾(ji)樣缺點，國(guo)內(nei)(nei)產(chan)品(pin)相(xiang)對(dui)國(guo)外產(chan)品(pin)的(de)(de)(de)優勢(shi)是非(fei)常大的(de)(de)(de)。
