四輪一帶-中特機械廠家-山推四輪一帶：

概述(shu)目前(qian)(qian)，2轎車的(de)4輪(lun)(lun)(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)裝置已(yi)經引進(jin)了電子計(ji)算(suan)機控制(zhi)系(xi)統，當前(qian)(qian)輪(lun)(lun)(lun)(lun)或(huo)后(hou)輪(lun)(lun)(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)時(shi)(shi)(shi)(shi)(shi)，車子隨時(shi)(shi)(shi)(shi)(shi)根據路(lu)面(mian)狀態的(de)反饋信息分(fen)配前(qian)(qian)后(hou)輪(lun)(lun)(lun)(lun)子的(de)動(dong)(dong)(dong)力，變為4輪(lun)(lun)(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)。4輪(lun)(lun)(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)又可以細分(fen)成(cheng)4種驅(qu)(qu)(qu)動(dong)(dong)(dong)模(mo)式(shi)：全(quan)時(shi)(shi)(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)（Full－Time）、分(fen)時(shi)(shi)(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)（Part-Time）、適時(shi)(shi)(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)（Real－Time）和分(fen)時(shi)(shi)(shi)(shi)(shi)/適時(shi)(shi)(shi)(shi)(shi)混和驅(qu)(qu)(qu)動(dong)(dong)(dong)。全(quan)時(shi)(shi)(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)全(quan)時(shi)(shi)(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)（Full－Time） 全(quan)時(shi)(shi)(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)的(de)特點(dian)就(jiu)是(shi)無(wu)論怎(zen)么樣，永遠都保持(chi)四輪(lun)(lun)(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)模(mo)式(shi)，這種傳動(dong)(dong)(dong)系(xi)統都是(shi)不(bu)(bu)需要駕(jia)駛(shi)人選擇(ze)操作的(de)。行(xing)駛(shi)的(de)時(shi)(shi)(shi)(shi)(shi)將(jiang)發動(dong)(dong)(dong)機輸出(chu)扭矩(ju)按50∶50 設定在前(qian)(qian)后(hou)輪(lun)(lun)(lun)(lun)上，使前(qian)(qian)后(hou)排車輪(lun)(lun)(lun)(lun)保持(chi)等量(liang)的(de)扭矩(ju)，遇到(dao)(dao)特別路(lu)面(mian)的(de)時(shi)(shi)(shi)(shi)(shi)候就(jiu)可以自動(dong)(dong)(dong)將(jiang)不(bu)(bu)同的(de)扭距(ju)分(fen)配到(dao)(dao)各(ge)個輪(lun)(lun)(lun)(lun)子上面(mian)。全(quan)時(shi)(shi)(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)系(xi)統具有(you)良好的(de)駕(jia)駛(shi)操控性和行(xing)駛(shi)循(xun)跡性，不(bu)(bu)過缺(que)點(dian)也是(shi)很明顯的(de)，那就(jiu)是(shi)比較廢油(you)，經濟性不(bu)(bu)夠好，而且車輛沒有(you)任何裝置來控制(zhi)輪(lun)(lun)(lun)(lun)胎(tai)轉速的(de)差異，一旦(dan)一個輪(lun)(lun)(lun)(lun)胎(tai)離開地(di)面(mian)就(jiu)有(you)可能讓(rang)你無(wu)法(fa)前(qian)(qian)進(jin)。

四(si)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)（4 Wheel Drive)主變(bian)(bian)速(su)(su)器通過一(yi)個輔助(zhu)變(bian)(bian)速(su)(su)器將動(dong)(dong)(dong)(dong)(dong)力傳(chuan)送到前輪(lun)和后輪(lun). 輔助(zhu)變(bian)(bian)速(su)(su)器通常(chang)(chang)有(you)三檔選(xuan)擇； 空(kong)(kong)檔，四(si)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)，四(si)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)低檔。空(kong)(kong)檔時(shi)，四(si)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)就變(bian)(bian)成了兩(liang)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)。四(si)輪(lun)驅(qu)(qu)(qu) 動(dong)(dong)(dong)(dong)(dong)適合于惡劣(lie)的(de)路面駕駛(shi)，例如，雨(yu)雪(xue)天和多沙石路面。四(si)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)低檔則適合高難度的(de)越野駕駛(shi)。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)是四(si)輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)的(de)一(yi)種. 它自動(dong)(dong)(dong)(dong)(dong)將發動(dong)(dong)(dong)(dong)(dong) 機提(ti)供的(de) 扭矩分送到前輪(lun)和后輪(lun)，不(bu)需(xu)要手動(dong)(dong)(dong)(dong)(dong)去調整，也沒(mei)有(you)低檔選(xuan)擇。全輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong) 減低了車輪(lun)打(da)滑(hua)的(de)程度，改善了駕駛(shi)者的(de)控車能力。全輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)通常(chang)(chang)是一(yi)種 正常(chang)(chang)路面駕駛(shi)系統，并不(bu)設(she)計用于越野駕駛(shi)。

 四輪一帶~挖掘機行業特點

挖掘機的安全性能：

       歐洲和(he)北(bei)美對工程(cheng)機械(xie)安(an)全(quan)性有嚴格的(de)法律規定，設備的(de)安(an)全(quan)性能能夠給操作人員提供安(an)心(xin)作業(ye)的(de)環境(jing)，提高(gao)操作人員的(de)安(an)全(quan)性。小型挖掘機的(de)安(an)全(quan)性能主要體現在(zai)駕駛(shi)室的(de)ROPS/FOPS設計(ji)上，在(zai)駕駛(shi)室的(de)試驗中應滿(man)(man)足以下(xia)性能要求(qiu)：①可(ke)滿(man)(man)足必須的(de)能量吸收;②可(ke)滿(man)(man)足必須的(de)抗荷載;③可(ke)確保乘員安(an)全(quan)區域;④無加固構(gou)件的(de)異常(破損、龜裂(lie))。四輪一帶(dai)

       在(zai)誤(wu)(wu)操(cao)(cao)作(zuo)(zuo)安(an)全(quan)保(bao)護方面主要采用的(de)技術有：中位啟動(dong)保(bao)護─安(an)全(quan)鎖(suo)桿在(zai)鎖(suo)定(ding)狀態下才(cai)能啟動(dong)發動(dong)機(ji);安(an)全(quan)手(shou)柄(bing)操(cao)(cao)作(zuo)(zuo)模式——如果安(an)全(quan)鎖(suo)處于鎖(suo)定(ding)狀態，操(cao)(cao)作(zuo)(zuo)手(shou)柄(bing)及行駛手(shou)柄(bing)的(de)操(cao)(cao)作(zuo)(zuo)無效，可防止誤(wu)(wu)操(cao)(cao)作(zuo)(zuo)導致事故;回轉(zhuan)自(zi)動(dong)鎖(suo)定(ding)——發動(dong)機(ji)熄(xi)火時，回轉(zhuan)馬達將(jiang)自(zi)動(dong)鎖(suo)定(ding)，因此運輸時不需(xu)要回轉(zhuan)鎖(suo)銷。四輪一(yi)帶
