變(bian)(bian)速(su)器齒輪的(de)作(zuo)用是輸(shu)出動力(li),實現變(bian)(bian)速(su)器傳動比的(de)變(bian)(bian)換,即實現換檔,以達到變(bian)(bian)速(su)的(de)作(zuo)用。變(bian)(bian)速(su)器齒輪經常在高轉速(su)、高負荷、轉速(su)和負荷不斷交變(bian)(bian)的(de)情(qing)況下工作(zuo),因此(ci)容易損(sun)壞(huai)。
1、輸出軸(主軸)倒(dao)檔齒(chi)輪,俗稱倒(dao)檔從動(dong)齒(chi)輪;
2、中間(jian)軸(zhou)(副軸(zhou))倒檔齒輪,一(yi)般與中間(jian)軸(zhou)制為(wei)一(yi)體;
3、倒(dao)檔(dang)惰輪,裝在(zai)倒(dao)檔(dang)軸上,用(yong)來進(jin)行變換輸出軸主(zhu)旋(xuan)向。
1、先安裝好掛鉤的所有叉子,安裝可以(yi)確(que)認(ren)的輸入軸、齒(chi)輪,以(yi)叉子為準,看是否安裝該部(bu)件,確(que)認(ren)是一(yi)檔、二檔,然后(hou)逐一(yi)安裝。
2、變(bian)(bian)(bian)速(su)器變(bian)(bian)(bian)速(su)器主(zhu)要是(shi)(shi)指汽車變(bian)(bian)(bian)速(su)器,分(fen)為手動(dong)(dong)(dong)(dong)、自動(dong)(dong)(dong)(dong)兩種(zhong)。手動(dong)(dong)(dong)(dong)變(bian)(bian)(bian)速(su)器主(zhu)要由(you)齒(chi)(chi)輪(lun)和軸構成(cheng),通過不(bu)同齒(chi)(chi)輪(lun)的(de)(de)組合產生(sheng)變(bian)(bian)(bian)速(su)轉矩(ju),另外一(yi)方面,自動(dong)(dong)(dong)(dong)變(bian)(bian)(bian)速(su)器AT由(you)液力(li)(li)變(bian)(bian)(bian)矩(ju)器、行(xing)星齒(chi)(chi)輪(lun)、液壓操作(zuo)(zuo)系統(tong)構成(cheng),通過流體傳(chuan)遞(di)(di)和齒(chi)(chi)輪(lun)的(de)(de)組合產生(sheng)變(bian)(bian)(bian)速(su)轉矩(ju)變(bian)(bian)(bian)速(su)器的(de)(de)功能是(shi)(shi)改變(bian)(bian)(bian)傳(chuan)動(dong)(dong)(dong)(dong)比使(shi)發動(dong)(dong)(dong)(dong)機在有(you)利的(de)(de)情況下工(gong)作(zuo)(zuo),在不(bu)改變(bian)(bian)(bian)發動(dong)(dong)(dong)(dong)機旋轉方向的(de)(de)情況下使(shi)汽車后退(tui)行(xing)駛,利用空檔切斷動(dong)(dong)(dong)(dong)力(li)(li)傳(chuan)遞(di)(di),使(shi)發動(dong)(dong)(dong)(dong)機能夠起動(dong)(dong)(dong)(dong)、怠速(su),使(shi)變(bian)(bian)(bian)速(su)器的(de)(de)換擋和動(dong)(dong)(dong)(dong)力(li)(li)輸出(chu)變(bian)(bian)(bian)得容易。
變速(su)器齒(chi)輪的安裝方法:
1、拉出撥叉軸,墊(dian)圈(quan)厚度是否合適,各處紙墊(dian)圈(quan)是否完好。組裝后,請旋(xuan)(xuan)轉(zhuan)輸入軸,依次掛上各擋塊進行主(zhu)操作,防止(zhi)安(an)裝錯誤和安(an)裝遺漏,并旋(xuan)(xuan)松拆(chai)卸順序和堵頭螺栓。檢查(cha)所有墊(dian)片;
2、按組(zu)裝(zhuang)順(shun)序安裝(zhuang)變速器(qi)時,其零部件組(zu)裝(zhuang)順(shun)序與拆卸時的順(shun)序相反,確(que)保各齒輪嚙合面。安裝(zhuang)過程(cheng)中請始(shi)終轉動配合;
3、請注意(yi)零件的潤滑,在(zai)安裝軸(zhou)承(cheng)前涂抹(mo)黃油或油。從鏈(lian)輪(lun)方(fang)向拉出輸出軸(zhou),然后(hou)拉出兩端的軸(zhou)承(cheng)。曾拆下(xia)倒檔軸(zhou)(或中間軸(zhou))及(ji)倒檔齒輪(lun)。
