換擋機構修理包簡介

換擋(dang)(dang)機構(gou)修理包。　汽車換擋(dang)(dang)機構(gou)的(de)(de)組成是(shi)檔(dang)(dang)桿(gan)，拉(la)線(xian)，選(xuan)檔(dang)(dang)及換檔(dang)(dang)結(jie)構(gou)，撥叉及同步(bu)器(qi)，其中擋(dang)(dang)桿(gan)的(de)(de)作(zuo)(zuo)用是(shi)對檔(dang)(dang)位進行控制，拉(la)線(xian)是(shi)拉(la)動檔(dang)(dang)位位置，選(xuan)檔(dang)(dang)的(de)(de)作(zuo)(zuo)用是(shi)掛擋(dang)(dang)或者檔(dang)(dang)位變化，撥叉及同步(bu)器(qi)的(de)(de)作(zuo)(zuo)用，是(shi)負責結(jie)合及分(fen)離(li)各個檔(dang)(dang)位齒輪。

手動(dong)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)器(qi)(qi)(qi)的(de)基(ji)本組成：輸(shu)(shu)入(ru)軸(zhou)、輸(shu)(shu)出軸(zhou)、差速(su)(su)(su)器(qi)(qi)(qi)、各擋(dang)(dang)齒(chi)輪(lun)、軸(zhou)承、同(tong)步器(qi)(qi)(qi)、換擋(dang)(dang)機構、撥(bo)(bo)叉、油封、潤滑油、殼體、輸(shu)(shu)出法蘭。手動(dong)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)器(qi)(qi)(qi)又稱機械(xie)式變(bian)(bian)(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)器(qi)(qi)(qi)，即必須用手撥(bo)(bo)動(dong)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)桿(gan)才能改變(bian)(bian)(bian)(bian)(bian)(bian)(bian)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)器(qi)(qi)(qi)的(de)齒(chi)輪(lun)嚙合位(wei)置(zhi)，改變(bian)(bian)(bian)(bian)(bian)(bian)(bian)傳(chuan)動(dong)比，以(yi)達(da)到變(bian)(bian)(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)的(de)目(mu)的(de)。轎車手動(dong)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)器(qi)(qi)(qi)大多為四擋(dang)(dang)或五擋(dang)(dang)有(you)級式齒(chi)輪(lun)傳(chuan)動(dong)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)器(qi)(qi)(qi)，通常帶同(tong)步器(qi)(qi)(qi)，換擋(dang)(dang)方便、噪音(yin)小，手動(dong)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)在操(cao)縱(zong)時必須踩(cai)下離(li)合，方可撥(bo)(bo)得動(dong)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)桿(gan)。根據其換擋(dang)(dang)手柄和變(bian)(bian)(bian)(bian)(bian)(bian)(bian)速(su)(su)(su)器(qi)(qi)(qi)的(de)相對位(wei)置(zhi)不一樣(yang)，有(you)兩種結構形式，分別是直(zhi)接操(cao)縱(zong)式和遠距離(li)操(cao)縱(zong)式。

一汽豐田RAV4簡介

RAV4是豐(feng)(feng)田公(gong)司微(wei)(wei)型(xing)(xing)多(duo)功(gong)能越(yue)野車(che)家族(zu)中(zhong)(zhong)(zhong)的基本型(xing)(xing)車(che)，意為(wei)四輪驅動(dong)的休閑運動(dong)車(che)。豐(feng)(feng)田幾乎(hu)完全是用豐(feng)(feng)田倉庫中(zhong)(zhong)(zhong)部件(jian)裝成了這輛(liang)微(wei)(wei)型(xing)(xing)車(che)由(you)于采用了豐(feng)(feng)田的可變進氣門(men)正時(shi)技術具有極(ji)為(wei)優(you)越(yue)的動(dong)力性(xing)能，中(zhong)(zhong)(zhong)速時(shi)的扭矩增大(da)。
