齊齊哈爾四輪一帶-柳工四輪一帶廠家-中特重工(多圖)：

概述目前(qian)(qian)(qian)，2轎車(che)的(de)(de)(de)4輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)裝置已經引進了電子(zi)計算機控(kong)制系(xi)(xi)統，當前(qian)(qian)(qian)輪(lun)(lun)(lun)或后輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)時(shi)，車(che)子(zi)隨時(shi)根據路面狀態的(de)(de)(de)反(fan)饋信息(xi)分配前(qian)(qian)(qian)后輪(lun)(lun)(lun)子(zi)的(de)(de)(de)動(dong)(dong)(dong)(dong)(dong)力，變為4輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)。4輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)又可以細分成4種驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)模式(shi)：全(quan)時(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)（Full－Time）、分時(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)（Part-Time）、適(shi)時(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)（Real－Time）和分時(shi)/適(shi)時(shi)混和驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)。全(quan)時(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)全(quan)時(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)（Full－Time） 全(quan)時(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)特(te)點就是無論怎么樣，永(yong)遠(yuan)都保持四(si)輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)模式(shi)，這種傳動(dong)(dong)(dong)(dong)(dong)系(xi)(xi)統都是不需要駕駛人選擇操作的(de)(de)(de)。行駛的(de)(de)(de)時(shi)將發動(dong)(dong)(dong)(dong)(dong)機輸出(chu)扭(niu)矩按(an)50∶50 設定在前(qian)(qian)(qian)后輪(lun)(lun)(lun)上(shang)(shang)，使前(qian)(qian)(qian)后排車(che)輪(lun)(lun)(lun)保持等量的(de)(de)(de)扭(niu)矩，遇到(dao)特(te)別路面的(de)(de)(de)時(shi)候就可以自動(dong)(dong)(dong)(dong)(dong)將不同的(de)(de)(de)扭(niu)距分配到(dao)各個輪(lun)(lun)(lun)子(zi)上(shang)(shang)面。全(quan)時(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)系(xi)(xi)統具有良(liang)好(hao)的(de)(de)(de)駕駛操控(kong)性和行駛循跡(ji)性，不過缺點也是很明顯的(de)(de)(de)，那就是比(bi)較廢油(you)，經濟性不夠好(hao)，而且車(che)輛(liang)沒(mei)有任(ren)何裝置來控(kong)制輪(lun)(lun)(lun)胎(tai)轉速(su)的(de)(de)(de)差異(yi)，一旦一個輪(lun)(lun)(lun)胎(tai)離開(kai)地面就有可能(neng)讓你無法前(qian)(qian)(qian)進。

分(fen)(fen)時(shi)(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)分(fen)(fen)時(shi)(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)就是由駕(jia)(jia)駛員(yuan)(yuan)根(gen)據(ju)路面情況(kuang)(kuang)，選(xuan)擇四(si)驅(qu)(qu)或(huo)(huo)(huo)者兩驅(qu)(qu)，這(zhe)也(ye)是一般(ban)越野(ye)車(che)或(huo)(huo)(huo)四(si)驅(qu)(qu)SUV 常見的驅(qu)(qu)動(dong)(dong)(dong)模(mo)(mo)式(shi)(shi)。分(fen)(fen)時(shi)(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)較(jiao)大(da)的特點就是人(ren)工(gong)操(cao)作，由駕(jia)(jia)駛員(yuan)(yuan)根(gen)據(ju)路面情況(kuang)(kuang)通(tong)(tong)過(guo)接通(tong)(tong)或(huo)(huo)(huo)斷(duan)開分(fen)(fen)動(dong)(dong)(dong)器來變化兩輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)或(huo)(huo)(huo)四(si)輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)模(mo)(mo)式(shi)(shi)，較(jiao)大(da)的優(you)點就是可(ke)以根(gen)據(ju)實際(ji)情況(kuang)(kuang)來選(xuan)取驅(qu)(qu)動(dong)(dong)(dong)模(mo)(mo)式(shi)(shi)，比(bi)較(jiao)經濟。就拿(na)普通(tong)(tong)的越野(ye)車(che)而(er)言，一般(ban)都有三種驅(qu)(qu)動(dong)(dong)(dong)模(mo)(mo)式(shi)(shi)可(ke)以選(xuan)擇：在(zai)公路上行駛使(shi)(shi)用(yong)(yong)2H 高(gao)速(su)(su)兩輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)檔，當遇到雨(yu)雪路況(kuang)(kuang)時(shi)(shi)(shi)選(xuan)擇4H 高(gao)速(su)(su)驅(qu)(qu)動(dong)(dong)(dong)增(zeng)強(qiang)車(che)輛的附著力(li)和操(cao)控(kong)性，而(er)面對(dui)惡劣路況(kuang)(kuang)的挑戰(zhan)時(shi)(shi)(shi)又可(ke)采用(yong)(yong)4L 低速(su)(su)四(si)輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)，使(shi)(shi)動(dong)(dong)(dong)力(li)作用(yong)(yong)在(zai)全部四(si)個車(che)輪(lun)(lun)(lun)上，從而(er)降低了對(dui)每(mei)個輪(lun)(lun)(lun)胎附著力(li)的要求，減小了轉(zhuan)彎(wan)時(shi)(shi)(shi)車(che)輪(lun)(lun)(lun)空轉(zhuan)的幾(ji)率(lv)，發(fa)動(dong)(dong)(dong)機制動(dong)(dong)(dong)能力(li)也(ye)得(de)以增(zeng)強(qiang)，極大(da)地(di)提高(gao)了車(che)輛在(zai)崎(qi)嶇或(huo)(huo)(huo)光(guang)滑路面行駛時(shi)(shi)(shi)在(zai)油門突然關閉的情況(kuang)(kuang)下的可(ke)控(kong)性。優(you)點是可(ke)根(gen)據(ju)實際(ji)情況(kuang)(kuang)來選(xuan)取驅(qu)(qu)動(dong)(dong)(dong)模(mo)(mo)式(shi)(shi)，比(bi)較(jiao)經濟；缺點是其機械結(jie)構比(bi)較(jiao)復雜，駕(jia)(jia)駛員(yuan)(yuan)要具(ju)有一定(ding)的經驗才能掌握好切換時(shi)(shi)(shi)機。

四輪一(yi)代(dai)市場(chang)如何進行供給側改(gai)革(ge)

目前的現狀是大家都在壓價格，拼營銷，山推、三一鏈條搞活動價格一低在低，四輪有的企業平進平出，一個輪子利潤幾塊錢都在做，造假不斷，搞笑的是，假l貨在市場上名氣很大了，反而原廠真的被視為假l貨；大部分企業也認識到單純比拼營銷已無法適應新的市場形勢，“練內功”成為企業關注的重點。四輪一帶

目前(qian)市場是，履帶(dai)(dai)要(yao)求質量(liang)高，利(li)潤相對(dui)高一(yi)些，很多代理商選擇(ze)大(da)廠(chang)的鏈軌去銷售，利(li)潤也算可(ke)以，四(si)輪像山推、三一(yi)、徐工、龍工的都價格超高，后市場基本不選擇(ze)，而一(yi)些小廠(chang)質量(liang)可(ke)靠價格略低的反而市場不錯，目前(qian)行情保持一(yi)周七天(tian)不休。四(si)輪一(yi)帶(dai)(dai)

大家都在拼價格導致整個四輪一帶后市場行業都不愿投入無法進行，加上勞動力成本逐年增加，企業較小私l募股權和創業投資很難進行，只有靠自己關系去主機廠搞新技術和國家稅收制度改革了。四輪(lun)一帶(dai)
