中特工程(圖)、軌鏈總成批發、大悟縣軌鏈總成：

汽車在(zai)行(xing)駛(shi)時(shi)，電腦利(li)用下述3種傳感器(qi)不斷檢測(ce)汽車的(de)行(xing)駛(shi)狀(zhuang)態(tai)，即(ji)4個車輪(lun)的(de)轉(zhuan)(zhuan)(zhuan)速(su)傳感器(qi)、汽車的(de)前(qian)(qian)(qian)后(hou)(hou)(hou)左右(you)加(jia)速(su)度傳感器(qi)、發動(dong)(dong)(dong)(dong)機(ji)轉(zhuan)(zhuan)(zhuan)速(su)傳感器(qi)。此外，利(li)用轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)盤轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)角傳感器(qi)、油門踏板開度傳感器(qi)不斷地判斷司機(ji)的(de)駕駛(shi)意(yi)圖，按預先給定的(de)程序進行(xing)綜合(he)控制。在(zai)AWD系統中，向(xiang)(xiang)前(qian)(qian)(qian)后(hou)(hou)(hou)車輪(lun)的(de)動(dong)(dong)(dong)(dong)力(li)分(fen)配(pei)(pei)(pei)(pei)影響到汽車的(de)行(xing)駛(shi)性(xing)能(neng)。如當(dang)汽車向(xiang)(xiang)前(qian)(qian)(qian)后(hou)(hou)(hou)輪(lun)驅(qu)動(dong)(dong)(dong)(dong)力(li)的(de)分(fen)配(pei)(pei)(pei)(pei)比為(wei)0:100時(shi)，具有較(jiao)高的(de)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)性(xing)能(neng)和(he)極限(xian)行(xing)駛(shi)性(xing)能(neng)，當(dang)驅(qu)動(dong)(dong)(dong)(dong)力(li)分(fen)配(pei)(pei)(pei)(pei)比為(wei)50:50時(shi)，穩定性(xing)得(de)到提高，但轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)性(xing)能(neng)和(he) 極限(xian)行(xing)駛(shi)性(xing)能(neng)會下降(jiang)。在(zai)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)性(xing)能(neng)、穩定性(xing)和(he)極限(xian)行(xing)駛(shi)性(xing)能(neng)之間要(yao)獲得(de)良好(hao)平衡，必須確定優(you)的(de)前(qian)(qian)(qian)后(hou)(hou)(hou)驅(qu)動(dong)(dong)(dong)(dong)力(li)分(fen)配(pei)(pei)(pei)(pei)系數(shu)，理(li)(li)想的(de)分(fen)配(pei)(pei)(pei)(pei)系數(shu)按照不同的(de)路(lu)面(mian)有所不同，在(zai)允許強力(li)加(jia)速(su)的(de)鋪裝路(lu)面(mian)上(shang)考慮到載(zai)荷轉(zhuan)(zhuan)(zhuan)移，以向(xiang)(xiang)后(hou)(hou)(hou)輪(lun)分(fen)配(pei)(pei)(pei)(pei)較(jiao)大驅(qu)動(dong)(dong)(dong)(dong)力(li)為(wei)宜。但是，在(zai)打滑的(de)路(lu)面(mian)，當(dang)向(xiang)(xiang)后(hou)(hou)(hou)輪(lun)分(fen)配(pei)(pei)(pei)(pei)較(jiao)大驅(qu)動(dong)(dong)(dong)(dong)力(li)時(shi)，就(jiu)會引起過度轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)。有資料認(ren)為(wei)，理(li)(li)想的(de)前(qian)(qian)(qian)后(hou)(hou)(hou)驅(qu)動(dong)(dong)(dong)(dong)力(li)分(fen)配(pei)(pei)(pei)(pei)比在(zai)3O ：70～50：50。目前(qian)(qian)(qian)，本(ben)田新(xin)一代Legend轎車的(de)SH—AWD能(neng)使前(qian)(qian)(qian)后(hou)(hou)(hou)驅(qu)動(dong)(dong)(dong)(dong)力(li)分(fen)配(pei)(pei)(pei)(pei)在(zai)70：30—30：70內(nei)連續(xu)變化(hua)。

分動(dong)(dong)(dong)器(qi)(qi)的功能是執行前后輪(lun)扭(niu)矩分配(pei)功能，在分動(dong)(dong)(dong)器(qi)(qi)中間(jian)布置一個濕(shi)式多(duo)片離合器(qi)(qi)，該離合器(qi)(qi)右(you)端(duan)(duan)通過傳(chuan)動(dong)(dong)(dong)軸驅(qu)動(dong)(dong)(dong)后輪(lun)，左(zuo)端(duan)(duan)通過鏈傳(chuan)動(dong)(dong)(dong)驅(qu)動(dong)(dong)(dong)前輪(lun)。電(dian)(dian)控單元（ECU)ECU是AWD系統(tong)的核心(xin)，其功用是根據制(zhi)(zhi)定(ding)的控制(zhi)(zhi)方案(an)，按照(zhao)編制(zhi)(zhi)的程(cheng)序對各(ge)種傳(chuan)感器(qi)(qi)輸(shu)(shu)入(ru)信號(hao)(hao)進(jin)行分析、計算(suan)、處理，輸(shu)(shu)出一定(ding)的控制(zhi)(zhi)信號(hao)(hao)指令，驅(qu)動(dong)(dong)(dong)電(dian)(dian)磁閥動(dong)(dong)(dong)作。AWD系統(tong)ECU主(zhu)要由輸(shu)(shu)入(ru)信號(hao)(hao)調理電(dian)(dian)路、微(wei)處理器(qi)(qi)、輸(shu)(shu)出信號(hao)(hao)處理電(dian)(dian)路、電(dian)(dian)源電(dian)(dian)路等硬件部分以及(ji)控制(zhi)(zhi)系統(tong)和(he)(he)控制(zhi)(zhi)程(cheng)序、軟件平臺等軟件部分組成。為保證控制(zhi)(zhi)系統(tong)可靠(kao)地工作，電(dian)(dian)控單元還必須(xu)采取有效(xiao)的抗干擾措(cuo)施(shi)和(he)(he)故(gu)障自診(zhen)斷處理措(cuo)施(shi)。

四(si)(si)(si)(si)輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)（4 Wheel Drive)主變速器通過一個輔(fu)助變速器將(jiang)動(dong)(dong)(dong)(dong)力傳送到(dao)(dao)前輪(lun)(lun)(lun)(lun)和后輪(lun)(lun)(lun)(lun). 輔(fu)助變速器通常(chang)(chang)有三(san)檔(dang)(dang)選(xuan)擇； 空檔(dang)(dang)，四(si)(si)(si)(si)輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)，四(si)(si)(si)(si)輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)低(di)檔(dang)(dang)。空檔(dang)(dang)時，四(si)(si)(si)(si)輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)就變成了兩輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)。四(si)(si)(si)(si)輪(lun)(lun)(lun)(lun)驅(qu)(qu) 動(dong)(dong)(dong)(dong)適合(he)于惡劣的(de)路面駕(jia)駛，例如，雨(yu)雪天和多沙石路面。四(si)(si)(si)(si)輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)低(di)檔(dang)(dang)則適合(he)高難(nan)度的(de)越(yue)野(ye)駕(jia)駛。全輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong) (All Wheel Drive)全輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)是四(si)(si)(si)(si)輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)的(de)一種. 它自動(dong)(dong)(dong)(dong)將(jiang)發動(dong)(dong)(dong)(dong) 機提供的(de) 扭(niu)矩分送到(dao)(dao)前輪(lun)(lun)(lun)(lun)和后輪(lun)(lun)(lun)(lun)，不需要手動(dong)(dong)(dong)(dong)去調整，也沒有低(di)檔(dang)(dang)選(xuan)擇。全輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong) 減低(di)了車輪(lun)(lun)(lun)(lun)打滑的(de)程度，改(gai)善了駕(jia)駛者的(de)控車能力。全輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)通常(chang)(chang)是一種 正(zheng)常(chang)(chang)路面駕(jia)駛系統，并不設計(ji)用于越(yue)野(ye)駕(jia)駛。
