石首市支重輪,中特工程,支重輪總成：

支重輪的主要結構：

輪(lun)(lun)體(ti)、支重(zhong)輪(lun)(lun)軸(zhou)、軸(zhou)套、密封圈(quan)、端蓋(gai)等相關部(bu)件構成。支重(zhong)輪(lun)(lun)可分為單邊支重(zhong)輪(lun)(lun)與雙邊支重(zhong)輪(lun)(lun)；挖掘機(ji)(ji)(ji)用(yong)支重(zhong)輪(lun)(lun)與推土(tu)(tu)機(ji)(ji)(ji)用(yong)支重(zhong)輪(lun)(lun)，挖掘機(ji)(ji)(ji)用(yong)支重(zhong)輪(lun)(lun)一(yi)般是(shi)黑色(se)油漆，推土(tu)(tu)機(ji)(ji)(ji)支重(zhong)輪(lun)(lun)一(yi)般是(shi)黃色(se)油漆。    

支(zhi)重輪容易出現在問題

A、輪體磨損(sun)。出現這種情況的(de)原因(yin)是采用(yong)的(de)鋼材(cai)不合格或者說材(cai)料熱處理時的(de)硬度(du)較(jiao)低，耐磨性不足；

B、漏(lou)油(you)。支重輪軸通過軸套(tao)一直(zhi)在(zai)(zai)旋轉，輪體內要加油(you)來潤(run)滑，但如果說(shuo)密封(feng)圈不好的(de)話，很容易(yi)產(chan)生漏(lou)油(you)的(de)現象，這樣軸與軸套(tao)在(zai)(zai)無潤(run)滑的(de)情況下，很容易(yi)磨損，造成產(chan)品無法進行(xing)使用。因(yin)此，

支重輪密封(feng)的好壞是作為(wei)衡量生(sheng)產公司產品質量的一個很重要的標準(zhun)。

現在買(mai)(mai)車(che)越來越普(pu)遍了，但是買(mai)(mai)車(che)的(de)學問也很大呢，買(mai)(mai)車(che)之前要查(cha)好多(duo)信息，今天筆者分享一下前輪驅(qu)動和后(hou)輪驅(qu)動的(de)區別：

前(qian)(qian)輪(lun)(lun)驅動(dong)(dong)FR：非常普遍，成本沒有(you)后輪(lun)(lun)驅動(dong)(dong)的高，結構比較(jiao)簡單，發動(dong)(dong)機和驅動(dong)(dong)部(bu)(bu)件都(dou)在前(qian)(qian)部(bu)(bu)分，由前(qian)(qian)面拉著(zhu)后面向前(qian)(qian)走(zou)，當速度過快轉彎的時候(hou)容易發生轉向不足(zu)，而且前(qian)(qian)輪(lun)(lun)驅動(dong)(dong)對前(qian)(qian)輪(lun)(lun)胎的損耗很大。

后(hou)輪驅動(dong)：結(jie)構比較(jiao)(jiao)復雜，成(cheng)本比較(jiao)(jiao)高；車的(de)重(zhong)量也比較(jiao)(jiao)重(zhong)，整個車重(zhong)的(de)分別比較(jiao)(jiao)均勻，但急速過彎道(dao)的(de)時候很容易(yi)發生漂移現象，一般豪華車都用(yong)后(hou)驅動(dong)。

四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)（4 Wheel Drive)主變(bian)(bian)速器(qi)通(tong)(tong)過一(yi)個輔助變(bian)(bian)速器(qi)將動(dong)(dong)(dong)(dong)(dong)力傳送到前(qian)輪(lun)和后輪(lun). 輔助變(bian)(bian)速器(qi)通(tong)(tong)常(chang)有三檔(dang)選擇； 空檔(dang)，四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)，四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)低(di)檔(dang)。空檔(dang)時，四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)就變(bian)(bian)成了兩輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)。四輪(lun)驅(qu)(qu)(qu) 動(dong)(dong)(dong)(dong)(dong)適合(he)于惡劣的路面(mian)駕(jia)駛，例如，雨雪天和多沙石路面(mian)。四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)低(di)檔(dang)則適合(he)高難度的越(yue)野駕(jia)駛。全輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong) (All Wheel Drive)全輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)是(shi)四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)的一(yi)種. 它自動(dong)(dong)(dong)(dong)(dong)將發動(dong)(dong)(dong)(dong)(dong) 機提供(gong)的 扭矩分送到前(qian)輪(lun)和后輪(lun)，不需要手動(dong)(dong)(dong)(dong)(dong)去調整，也沒(mei)有低(di)檔(dang)選擇。全輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong) 減低(di)了車輪(lun)打滑的程度，改善(shan)了駕(jia)駛者的控車能力。全輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)通(tong)(tong)常(chang)是(shi)一(yi)種 正常(chang)路面(mian)駕(jia)駛系統，并(bing)不設計用(yong)于越(yue)野駕(jia)駛。
