北京履帶驅動輪_挖掘機履帶驅動輪_中特工程：

ESC、TCS系統通過控制發(fa)動(dong)(dong)(dong)(dong)機動(dong)(dong)(dong)(dong)力(li)輸(shu)出和制動(dong)(dong)(dong)(dong)系統來(lai)保證平穩駕(jia)駛，以損失動(dong)(dong)(dong)(dong)力(li)作為安全(quan)(quan)保證以防止超(chao)越物理(li)極限(xian)(xian)；AWD控制并調(diao)整(zheng)每個車輪(lun)(lun)的(de)(de)扭(niu)矩輸(shu)出，在不干涉發(fa)動(dong)(dong)(dong)(dong)機動(dong)(dong)(dong)(dong)力(li)輸(shu)出的(de)(de)情(qing)況(kuang)下提高了物理(li)極限(xian)(xian)，保證你(ni)全(quan)(quan)天(tian)候(hou)的(de)(de)駕(jia)駛樂趣。車輛的(de)(de)驅動(dong)(dong)(dong)(dong)型(xing)(xing)式有(you)FWD(Front-Wheel Drive）、RWD(Rear-Wheel Drive）、4WD(Four-Wheel Drive）和AWD(All-Wheel Drive）。我(wo)們(men)先來(lai)看看這幾種驅動(dong)(dong)(dong)(dong)型(xing)(xing)式。前輪(lun)(lun)驅動(dong)(dong)(dong)(dong)（FWD）：今(jin)天(tian)占(zhan)轎(jiao)車產(chan)品的(de)(de)70%的(de)(de)經濟(ji)型(xing)(xing)及中級轎(jiao)車都采用了前輪(lun)(lun)驅動(dong)(dong)(dong)(dong)。就像名字(zi)所暗示的(de)(de)，只有(you)前輪(lun)(lun)傳(chuan)遞動(dong)(dong)(dong)(dong)力(li)。安裝在前部的(de)(de)發(fa)動(dong)(dong)(dong)(dong)機將(jiang)動(dong)(dong)(dong)(dong)力(li)直(zhi)接(jie)傳(chuan)輸(shu)到前輪(lun)(lun)，提高了牽引效率(lv)，60%～70%的(de)(de)重量(liang)集中在轎(jiao)車前部，提供了更好的(de)(de)冰雪(xue)穩定(ding)性，但前輪(lun)(lun)要承受(shou)75%的(de)(de)制動(dong)(dong)(dong)(dong)，而且在急加速時車身重心后(hou)移，就會造成加速延遲，在操控上(shang)也存在著轉向(xiang)過度和后(hou)輪(lun)(lun)打滑現(xian)象。

減輕整車(che)的重(zhong)量是前(qian)(qian)輪驅(qu)動的另一個(ge)優點。減輕車(che)重(zhong)可以提高加速性，制(zhi)動性和燃油(you)經濟性。由于(yu)前(qian)(qian)輪驅(qu)動的汽車(che)的驅(qu)動輪承受著發(fa)動機(ji)和驅(qu)動橋(qiao)的重(zhong)量，可以增加驅(qu)動輪的附著力，這對于(yu)在濕滑路面上行駛的汽車(che)將(jiang)會有很大的幫(bang)助。

前輪驅動(dong)的(de)的(de)優點還在于可以(yi)擁有大(da)的(de)室內(nei)空(kong)間(jian)，駕駛室內(nei)不會因為(wei)有驅動(dong)軸通過而有一個大(da)的(de)凸起。看(kan)(kan)看(kan)(kan)本田思域(Civic)，你就會發(fa)現這種小車(che)也(ye)可以(yi)擁有許多(duo)轎(jiao)車(che)無法(fa)比(bi)擬的(de)后(hou)(hou)座空(kong)間(jian)，原(yuan)因就是有了(le)一個平整的(de)底(di)板，同時，沒有了(le)后(hou)(hou)差速器，行李(li)箱的(de)空(kong)間(jian)也(ye)會得到(dao)增大(da)。

分動(dong)(dong)(dong)(dong)器(qi)(qi)的(de)功(gong)能是(shi)執(zhi)行前(qian)后輪扭矩分配功(gong)能，在分動(dong)(dong)(dong)(dong)器(qi)(qi)中間布置(zhi)一個濕式(shi)多片離(li)(li)合器(qi)(qi)，該(gai)離(li)(li)合器(qi)(qi)右(you)端通過傳(chuan)動(dong)(dong)(dong)(dong)軸(zhou)驅動(dong)(dong)(dong)(dong)后輪，左端通過鏈(lian)傳(chuan)動(dong)(dong)(dong)(dong)驅動(dong)(dong)(dong)(dong)前(qian)輪。電(dian)(dian)(dian)(dian)控(kong)單元（ECU)ECU是(shi)AWD系(xi)統(tong)(tong)的(de)核心，其功(gong)用是(shi)根據制(zhi)定的(de)控(kong)制(zhi)方案，按照編(bian)制(zhi)的(de)程(cheng)(cheng)序對(dui)各種傳(chuan)感器(qi)(qi)輸入信(xin)號(hao)進行分析、計算、處(chu)理(li)(li)(li)，輸出一定的(de)控(kong)制(zhi)信(xin)號(hao)指令，驅動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)磁(ci)閥動(dong)(dong)(dong)(dong)作。AWD系(xi)統(tong)(tong)ECU主要由輸入信(xin)號(hao)調(diao)理(li)(li)(li)電(dian)(dian)(dian)(dian)路(lu)、微(wei)處(chu)理(li)(li)(li)器(qi)(qi)、輸出信(xin)號(hao)處(chu)理(li)(li)(li)電(dian)(dian)(dian)(dian)路(lu)、電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路(lu)等(deng)硬件(jian)部分以及控(kong)制(zhi)系(xi)統(tong)(tong)和控(kong)制(zhi)程(cheng)(cheng)序、軟件(jian)平臺等(deng)軟件(jian)部分組成。為保(bao)證控(kong)制(zhi)系(xi)統(tong)(tong)可(ke)靠地工作，電(dian)(dian)(dian)(dian)控(kong)單元還必須采取(qu)有效的(de)抗干擾措(cuo)施和故障自(zi)診斷處(chu)理(li)(li)(li)措(cuo)施。
