換擋機構修理包簡介

換(huan)擋機構修理包(bao)。　汽車換(huan)擋機構的(de)組成是(shi)檔(dang)(dang)桿，拉(la)線，選檔(dang)(dang)及換(huan)檔(dang)(dang)結構，撥(bo)叉(cha)及同步器，其中擋桿的(de)作用(yong)是(shi)對檔(dang)(dang)位(wei)(wei)進行控制，拉(la)線是(shi)拉(la)動檔(dang)(dang)位(wei)(wei)位(wei)(wei)置，選檔(dang)(dang)的(de)作用(yong)是(shi)掛擋或者(zhe)檔(dang)(dang)位(wei)(wei)變化，撥(bo)叉(cha)及同步器的(de)作用(yong)，是(shi)負(fu)責結合(he)及分(fen)離各(ge)個檔(dang)(dang)位(wei)(wei)齒輪(lun)。

手(shou)(shou)動(dong)(dong)(dong)變(bian)(bian)(bian)(bian)速(su)(su)器(qi)(qi)的(de)基本組成(cheng)：輸(shu)(shu)入軸(zhou)、輸(shu)(shu)出軸(zhou)、差速(su)(su)器(qi)(qi)、各擋齒輪(lun)、軸(zhou)承、同步器(qi)(qi)、換擋機(ji)構(gou)(gou)、撥叉(cha)、油封、潤滑(hua)油、殼體、輸(shu)(shu)出法蘭。手(shou)(shou)動(dong)(dong)(dong)變(bian)(bian)(bian)(bian)速(su)(su)器(qi)(qi)又稱(cheng)機(ji)械式(shi)變(bian)(bian)(bian)(bian)速(su)(su)器(qi)(qi)，即必(bi)須用手(shou)(shou)撥動(dong)(dong)(dong)變(bian)(bian)(bian)(bian)速(su)(su)桿(gan)才(cai)能(neng)改變(bian)(bian)(bian)(bian)變(bian)(bian)(bian)(bian)速(su)(su)器(qi)(qi)的(de)齒輪(lun)嚙合位(wei)置，改變(bian)(bian)(bian)(bian)傳(chuan)動(dong)(dong)(dong)比，以(yi)達到變(bian)(bian)(bian)(bian)速(su)(su)的(de)目(mu)的(de)。轎車手(shou)(shou)動(dong)(dong)(dong)變(bian)(bian)(bian)(bian)速(su)(su)器(qi)(qi)大多為(wei)四擋或五(wu)擋有(you)級式(shi)齒輪(lun)傳(chuan)動(dong)(dong)(dong)變(bian)(bian)(bian)(bian)速(su)(su)器(qi)(qi)，通(tong)常帶同步器(qi)(qi)，換擋方便、噪音小，手(shou)(shou)動(dong)(dong)(dong)變(bian)(bian)(bian)(bian)速(su)(su)在操(cao)縱時(shi)必(bi)須踩下離(li)(li)合，方可撥得動(dong)(dong)(dong)變(bian)(bian)(bian)(bian)速(su)(su)桿(gan)。根據其換擋手(shou)(shou)柄和變(bian)(bian)(bian)(bian)速(su)(su)器(qi)(qi)的(de)相對位(wei)置不(bu)一樣，有(you)兩(liang)種結構(gou)(gou)形式(shi)，分別是直接操(cao)縱式(shi)和遠距離(li)(li)操(cao)縱式(shi)。

寶馬3系(進口)簡介

作為寶馬的(de)(de)當家花旦(dan)，3系以(yi)卓(zhuo)越的(de)(de)性能，特有(you)的(de)(de)駕駛樂(le)趣(qu)，得(de)到了(le)真正的(de)(de)世界(jie)車的(de)(de)美譽，被(bei)(bei)認(ren)為是全球緊湊級(ji)豪華轎車執牛耳者(zhe)，而其真實表現也不(bu)愧于這個稱號(hao)。干練舒展的(de)(de)車身造型，已經(jing)可以(yi)被(bei)(bei)歸入經(jing)典設(she)計(ji)的(de)(de)行列，車內空(kong)間也許在(zai)眾多國人(ren)的(de)(de)認(ren)識中會(hui)覺得(de)很小，但我們認(ren)為，其空(kong)間也絕對夠用，不(bu)能成為拒絕購買(mai)的(de)(de)理(li)由，前置(zhi)發(fa)動(dong)(dong)機加(jia)后(hou)輪驅動(dong)(dong)，是其真正的(de)(de)精髓所在(zai)。
