ESC、TCS系統(tong)通過控制(zhi)發(fa)(fa)動(dong)(dong)(dong)機(ji)動(dong)(dong)(dong)力(li)輸(shu)出(chu)和制(zhi)動(dong)(dong)(dong)系統(tong)來保證平穩(wen)駕(jia)駛，以(yi)損失動(dong)(dong)(dong)力(li)作為安全保證以(yi)防止超越物理極(ji)限；AWD控制(zhi)并調(diao)整每個車輪的(de)(de)(de)(de)扭矩輸(shu)出(chu)，在(zai)不干涉發(fa)(fa)動(dong)(dong)(dong)機(ji)動(dong)(dong)(dong)力(li)輸(shu)出(chu)的(de)(de)(de)(de)情況(kuang)下(xia)提(ti)高(gao)了(le)物理極(ji)限，保證你全天候的(de)(de)(de)(de)駕(jia)駛樂趣。車輛(liang)的(de)(de)(de)(de)驅動(dong)(dong)(dong)型(xing)式(shi)(shi)有FWD(Front-Wheel Drive）、RWD(Rear-Wheel Drive）、4WD(Four-Wheel Drive）和AWD(All-Wheel Drive）。我們先(xian)來看(kan)看(kan)這幾種驅動(dong)(dong)(dong)型(xing)式(shi)(shi)。前(qian)輪驅動(dong)(dong)(dong)（FWD）：今天占轎(jiao)(jiao)車產品的(de)(de)(de)(de)70%的(de)(de)(de)(de)經濟(ji)型(xing)及(ji)中(zhong)級轎(jiao)(jiao)車都采用了(le)前(qian)輪驅動(dong)(dong)(dong)。就像名字所暗(an)示的(de)(de)(de)(de)，只(zhi)有前(qian)輪傳(chuan)遞動(dong)(dong)(dong)力(li)。安裝在(zai)前(qian)部的(de)(de)(de)(de)發(fa)(fa)動(dong)(dong)(dong)機(ji)將(jiang)動(dong)(dong)(dong)力(li)直接傳(chuan)輸(shu)到(dao)前(qian)輪，提(ti)高(gao)了(le)牽引效(xiao)率(lv)，60%～70%的(de)(de)(de)(de)重量(liang)集(ji)中(zhong)在(zai)轎(jiao)(jiao)車前(qian)部，提(ti)供了(le)更好的(de)(de)(de)(de)冰(bing)雪穩(wen)定性，但前(qian)輪要承受75%的(de)(de)(de)(de)制(zhi)動(dong)(dong)(dong)，而且在(zai)急加(jia)速時車身后(hou)移(yi)，就會(hui)造成加(jia)速延遲，在(zai)操控上也(ye)存在(zai)著轉向過度和后(hou)輪打滑現象。

四(si)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)（4 Wheel Drive)主變(bian)(bian)速(su)器(qi)通過一(yi)個(ge)輔助(zhu)變(bian)(bian)速(su)器(qi)將動(dong)(dong)(dong)力傳送到(dao)前輪(lun)和后輪(lun). 輔助(zhu)變(bian)(bian)速(su)器(qi)通常(chang)有(you)(you)三檔選擇(ze)； 空(kong)檔，四(si)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)，四(si)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)低(di)(di)檔。空(kong)檔時(shi)，四(si)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)就變(bian)(bian)成了兩輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)。四(si)輪(lun)驅(qu)(qu)(qu) 動(dong)(dong)(dong)適合于惡劣的(de)(de)路面(mian)駕(jia)駛(shi)(shi)，例如，雨雪天和多沙石路面(mian)。四(si)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)低(di)(di)檔則適合高難度的(de)(de)越(yue)野駕(jia)駛(shi)(shi)。全(quan)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong) (All Wheel Drive)全(quan)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)是四(si)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)的(de)(de)一(yi)種. 它自動(dong)(dong)(dong)將發動(dong)(dong)(dong) 機提供的(de)(de) 扭(niu)矩分送到(dao)前輪(lun)和后輪(lun)，不需要手動(dong)(dong)(dong)去調整，也(ye)沒(mei)有(you)(you)低(di)(di)檔選擇(ze)。全(quan)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong) 減低(di)(di)了車輪(lun)打滑(hua)的(de)(de)程度，改善了駕(jia)駛(shi)(shi)者的(de)(de)控(kong)車能(neng)力。全(quan)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)通常(chang)是一(yi)種 正常(chang)路面(mian)駕(jia)駛(shi)(shi)系(xi)統，并不設計用于越(yue)野駕(jia)駛(shi)(shi)。

四輪一帶~挖掘機行業特點

挖掘機維修保養技術：

       從日常保(bao)養維護(hu)(hu)到正規檢查維修，簡單化的(de)操作(zuo)是(shi)十分必要的(de)，能夠(gou)提高機(ji)器的(de)可靠性，使機(ji)器始終保(bao)持(chi)良好狀態。要使得日常檢查方便快捷，實現(xian)無須借助工具(ju)的(de)一觸式操作(zuo)。維護(hu)(hu)修理簡單易(yi)行，可快速(su)進行內部的(de)所有檢查維修。四輪一帶

       挖掘(jue)機(ji)(ji)械行業(ye)市場調查分析報告顯示，以液(ye)(ye)壓挖掘(jue)機(ji)(ji)為(wei)例，其主(zhu)(zhu)要(yao)作(zuo)(zuo)業(ye)工(gong)況(kuang)是挖掘(jue)和(he)裝(zhuang)車。對(dui)這兩種工(gong)況(kuang)，動(dong)臂(bei)的起(qi)升(sheng)速(su)度(du)是決定工(gong)作(zuo)(zuo)循(xun)環時(shi)間(jian)的主(zhu)(zhu)要(yao)因素，動(dong)臂(bei)起(qi)升(sheng)速(su)度(du)越(yue)快，循(xun)環時(shi)間(jian)就越(yue)短，機(ji)(ji)器的工(gong)作(zuo)(zuo)效率也(ye)就越(yue)高(gao)。為(wei)提(ti)高(gao)動(dong)臂(bei)的起(qi)升(sheng)速(su)度(du)，卡l特彼勒OB系列挖掘(jue)機(ji)(ji)除了將動(dong)臂(bei)起(qi)升(sheng)、斗桿(gan)外伸(shen)和(he)斗桿(gan)內收動(dong)作(zuo)(zuo)設計由(you)雙泵合流完成外，還通過(guo)電控方式在機(ji)(ji)器聯合動(dong)作(zuo)(zuo)需要(yao)動(dong)臂(bei)快速(su)起(qi)升(sheng)時(shi)取(qu)消斗桿(gan)內收的合流功能，進(jin)一(yi)步加快動(dong)臂(bei)起(qi)升(sheng)的速(su)度(du)。對(dui)動(dong)臂(bei)的這種控制方式稱為(wei)“動(dong)臂(bei)優先(xian)”模式，是液(ye)(ye)壓挖掘(jue)機(ji)(ji)性能改良(liang)方面(mian)的一(yi)個技術發展趨勢(shi)。四輪一(yi)帶
