換擋機構修理包簡介

換(huan)擋機構修理包。　汽車換(huan)擋機構的(de)組成(cheng)是(shi)(shi)檔(dang)(dang)桿，拉線(xian)，選檔(dang)(dang)及(ji)換(huan)檔(dang)(dang)結(jie)構，撥(bo)叉及(ji)同步(bu)(bu)器，其中(zhong)擋桿的(de)作(zuo)用是(shi)(shi)對檔(dang)(dang)位(wei)(wei)進(jin)行控制，拉線(xian)是(shi)(shi)拉動檔(dang)(dang)位(wei)(wei)位(wei)(wei)置，選檔(dang)(dang)的(de)作(zuo)用是(shi)(shi)掛(gua)擋或者(zhe)檔(dang)(dang)位(wei)(wei)變化，撥(bo)叉及(ji)同步(bu)(bu)器的(de)作(zuo)用，是(shi)(shi)負責結(jie)合及(ji)分離各個檔(dang)(dang)位(wei)(wei)齒(chi)輪(lun)。

手(shou)動(dong)(dong)(dong)變(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)(su)(su)器的(de)基本組(zu)成：輸入軸(zhou)、輸出軸(zhou)、差速(su)(su)(su)(su)(su)器、各擋齒(chi)輪(lun)、軸(zhou)承、同(tong)步(bu)器、換(huan)擋機(ji)構(gou)、撥(bo)叉、油封、潤(run)滑油、殼體(ti)、輸出法蘭。手(shou)動(dong)(dong)(dong)變(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)(su)(su)器又稱機(ji)械式(shi)(shi)變(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)(su)(su)器，即必(bi)須用手(shou)撥(bo)動(dong)(dong)(dong)變(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)(su)(su)桿才能(neng)改變(bian)(bian)(bian)(bian)(bian)變(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)(su)(su)器的(de)齒(chi)輪(lun)嚙合(he)位置，改變(bian)(bian)(bian)(bian)(bian)傳動(dong)(dong)(dong)比，以達到變(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)(su)(su)的(de)目的(de)。轎車手(shou)動(dong)(dong)(dong)變(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)(su)(su)器大(da)多為(wei)四(si)擋或五(wu)擋有(you)級式(shi)(shi)齒(chi)輪(lun)傳動(dong)(dong)(dong)變(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)(su)(su)器，通常(chang)帶(dai)同(tong)步(bu)器，換(huan)擋方便(bian)、噪音小，手(shou)動(dong)(dong)(dong)變(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)(su)(su)在操縱時必(bi)須踩(cai)下離合(he)，方可撥(bo)得動(dong)(dong)(dong)變(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)(su)(su)桿。根據(ju)其(qi)換(huan)擋手(shou)柄和(he)變(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)(su)(su)器的(de)相對位置不(bu)一樣(yang)，有(you)兩(liang)種結(jie)構(gou)形式(shi)(shi)，分別是(shi)直(zhi)接操縱式(shi)(shi)和(he)遠距離操縱式(shi)(shi)。
