求購四輪一帶、赤壁市四輪一帶、中特工程：

輪體(ti)、支(zhi)重(zhong)輪軸、軸套(tao)、密(mi)封圈(quan)、端蓋(gai)等相關(guan)部件構成。支(zhi)重(zhong)輪可(ke)分為(wei)單(dan)邊支(zhi)重(zhong)輪與(yu)雙邊支(zhi)重(zhong)輪；挖(wa)掘機(ji)(ji)用(yong)(yong)支(zhi)重(zhong)輪與(yu)推(tui)土機(ji)(ji)用(yong)(yong)支(zhi)重(zhong)輪，挖(wa)掘機(ji)(ji)用(yong)(yong)支(zhi)重(zhong)輪一般是(shi)黑色(se)油漆，推(tui)土機(ji)(ji)支(zhi)重(zhong)輪一般是(shi)黃色(se)油漆

支(zhi)重輪輪體材(cai)料(liao)一般(ban)50Mn、40Mn2、等(deng)材(cai)料(liao)，主(zhu)要(yao)工(gong)藝鑄造或鍛造，機(ji)械加(jia)工(gong)，然后進行熱處理，輪子(zi)(zi)表面淬火后的(de)硬度(du)要(yao)達(da)到HRC45~52，以增(zeng)加(jia)輪子(zi)(zi)表面的(de)耐磨性。支(zhi)重輪軸的(de)加(jia)工(gong)精度(du)要(yao)求(qiu)(qiu)比較(jiao)高(gao)，一般(ban)是需要(yao)數控機(ji)床進行加(jia)工(gong)才(cai)能達(da)到要(yao)求(qiu)(qiu)。材(cai)料(liao)以40Mn2較(jiao)多，加(jia)工(gong)后也要(yao)進行淬火熱處理，硬度(du)達(da)到HRC42左右(you)

分(fen)(fen)動(dong)(dong)(dong)器的功(gong)能是執(zhi)行前(qian)(qian)后(hou)輪(lun)扭矩(ju)分(fen)(fen)配功(gong)能，在(zai)分(fen)(fen)動(dong)(dong)(dong)器中間(jian)布置(zhi)一個濕式多片離合器，該離合器右端通(tong)過傳動(dong)(dong)(dong)軸驅動(dong)(dong)(dong)后(hou)輪(lun)，左端通(tong)過鏈傳動(dong)(dong)(dong)驅動(dong)(dong)(dong)前(qian)(qian)輪(lun)。電(dian)控單(dan)元（ECU)ECU是AWD系統的核心，其功(gong)用是根據制(zhi)(zhi)定(ding)的控制(zhi)(zhi)方案，按(an)照編(bian)制(zhi)(zhi)的程序對(dui)各種傳感器輸入(ru)信號(hao)進行分(fen)(fen)析(xi)、計算(suan)、處(chu)理，輸出(chu)一定(ding)的控制(zhi)(zhi)信號(hao)指令，驅動(dong)(dong)(dong)電(dian)磁(ci)閥動(dong)(dong)(dong)作。AWD系統ECU主要(yao)由輸入(ru)信號(hao)調理電(dian)路、微處(chu)理器、輸出(chu)信號(hao)處(chu)理電(dian)路、電(dian)源電(dian)路等(deng)硬件部分(fen)(fen)以及控制(zhi)(zhi)系統和(he)控制(zhi)(zhi)程序、軟件平臺等(deng)軟件部分(fen)(fen)組成。為保證(zheng)控制(zhi)(zhi)系統可靠地工(gong)作，電(dian)控單(dan)元還必須采取有效的抗干擾措施(shi)和(he)故障(zhang)自(zi)診斷處(chu)理措施(shi)。
