換擋機構修理包簡介

換(huan)(huan)擋(dang)機(ji)構(gou)修(xiu)理包。　汽車(che)換(huan)(huan)擋(dang)機(ji)構(gou)的(de)組成(cheng)是(shi)(shi)檔桿，拉(la)線，選(xuan)檔及(ji)換(huan)(huan)檔結(jie)構(gou)，撥叉及(ji)同步器，其中擋(dang)桿的(de)作用(yong)是(shi)(shi)對(dui)檔位(wei)(wei)進行(xing)控制，拉(la)線是(shi)(shi)拉(la)動(dong)檔位(wei)(wei)位(wei)(wei)置，選(xuan)檔的(de)作用(yong)是(shi)(shi)掛擋(dang)或者檔位(wei)(wei)變化，撥叉及(ji)同步器的(de)作用(yong)，是(shi)(shi)負責結(jie)合及(ji)分離各個檔位(wei)(wei)齒輪。

手(shou)動(dong)(dong)變(bian)(bian)(bian)速(su)(su)器(qi)的(de)(de)基本組成：輸入軸(zhou)、輸出軸(zhou)、差速(su)(su)器(qi)、各擋齒輪(lun)、軸(zhou)承、同(tong)(tong)步(bu)器(qi)、換(huan)擋機(ji)(ji)構、撥叉、油封、潤(run)滑油、殼體、輸出法蘭。手(shou)動(dong)(dong)變(bian)(bian)(bian)速(su)(su)器(qi)又稱機(ji)(ji)械式(shi)(shi)變(bian)(bian)(bian)速(su)(su)器(qi)，即必(bi)(bi)須用(yong)手(shou)撥動(dong)(dong)變(bian)(bian)(bian)速(su)(su)桿才能改變(bian)(bian)(bian)變(bian)(bian)(bian)速(su)(su)器(qi)的(de)(de)齒輪(lun)嚙(nie)合位(wei)置(zhi)，改變(bian)(bian)(bian)傳動(dong)(dong)比，以(yi)達到變(bian)(bian)(bian)速(su)(su)的(de)(de)目的(de)(de)。轎車手(shou)動(dong)(dong)變(bian)(bian)(bian)速(su)(su)器(qi)大(da)多為四擋或五擋有(you)級式(shi)(shi)齒輪(lun)傳動(dong)(dong)變(bian)(bian)(bian)速(su)(su)器(qi)，通常帶同(tong)(tong)步(bu)器(qi)，換(huan)擋方便(bian)、噪音(yin)小，手(shou)動(dong)(dong)變(bian)(bian)(bian)速(su)(su)在操(cao)縱時必(bi)(bi)須踩下離(li)(li)合，方可撥得(de)動(dong)(dong)變(bian)(bian)(bian)速(su)(su)桿。根據(ju)其(qi)換(huan)擋手(shou)柄和(he)變(bian)(bian)(bian)速(su)(su)器(qi)的(de)(de)相對位(wei)置(zhi)不一樣，有(you)兩種結構形式(shi)(shi)，分別是直(zhi)接操(cao)縱式(shi)(shi)和(he)遠距離(li)(li)操(cao)縱式(shi)(shi)。
