五檔同步器簡介

五檔同步器。車同步器的作用是使接合套與待嚙合的齒圈迅速同步，縮短換擋時間。防止接合套與待嚙合的齒圈在同步前嚙合而產生接合齒之間的沖擊，使換擋較為順當，減少換擋齒輪噪聲。

更(geng)多資料如下：

1、同(tong)(tong)(tong)(tong)步(bu)(bu)器的(de)(de)(de)組成：由同(tong)(tong)(tong)(tong)一步(bu)(bu)裝置(zhi)（包(bao)括(kuo)推動件(jian)、摩擦件(jian)）、鎖(suo)止裝置(zhi)和接合裝置(zhi)三部分組成。同(tong)(tong)(tong)(tong)步(bu)(bu)器有(you)常壓式(shi)(shi)(shi)、慣性(xing)式(shi)(shi)(shi)、自增力式(shi)(shi)(shi)等多(duo)種。目前(qian)所有(you)的(de)(de)(de)同(tong)(tong)(tong)(tong)步(bu)(bu)器幾乎(hu)都采用摩擦慣性(xing)式(shi)(shi)(shi)同(tong)(tong)(tong)(tong)步(bu)(bu)裝置(zhi)，根據鎖(suo)止裝置(zhi)的(de)(de)(de)不同(tong)(tong)(tong)(tong)，又分為(wei)鎖(suo)環式(shi)(shi)(shi)慣性(xing)同(tong)(tong)(tong)(tong)步(bu)(bu)器和鎖(suo)銷式(shi)(shi)(shi)慣性(xing)同(tong)(tong)(tong)(tong)步(bu)(bu)器。

2、除(chu)了倒擋(dang)和一檔外(wai)，其他(ta)檔位均(jun)(jun)(jun)配置同(tong)(tong)(tong)(tong)步(bu)器(qi)(qi)：目前(qian)，在大(da)(da)(da)多數(shu)轎車(che)和大(da)(da)(da)貨車(che)上，除(chu)了倒擋(dang)和一檔外(wai)，其他(ta)檔位均(jun)(jun)(jun)配置同(tong)(tong)(tong)(tong)步(bu)器(qi)(qi)，并(bing)且對同(tong)(tong)(tong)(tong)步(bu)器(qi)(qi)的(de)要求是轉(zhuan)矩容量大(da)(da)(da)，性(xing)能(neng)穩定，耐(nai)用(yong)，具備(bei)良好的(de)經(jing)濟性(xing)。一般(ban)而言，大(da)(da)(da)多數(shu)汽車(che)均(jun)(jun)(jun)配備(bei)慣性(xing)同(tong)(tong)(tong)(tong)步(bu)器(qi)(qi)。慣性(xing)式同(tong)(tong)(tong)(tong)步(bu)器(qi)(qi)能(neng)確(que)保(bao)同(tong)(tong)(tong)(tong)步(bu)嚙合(he)換擋(dang)，性(xing)能(neng)穩定可靠。它可分為兩(liang)大(da)(da)(da)類：慣性(xing)鎖(suo)(suo)止(zhi)式同(tong)(tong)(tong)(tong)步(bu)器(qi)(qi)和慣性(xing)增力式同(tong)(tong)(tong)(tong)步(bu)器(qi)(qi)。使用(yong)最廣(guang)泛的(de)是鎖(suo)(suo)環(huan)式，鎖(suo)(suo)銷式等慣性(xing)鎖(suo)(suo)止(zhi)式同(tong)(tong)(tong)(tong)步(bu)器(qi)(qi)。

同步器的作用

手動(dong)變(bian)速箱(xiang)的(de)結(jie)構內部有(you)一個非常重要(yao)的(de)設備，那(nei)就(jiu)是(shi)"同步器(qi)”。同步器(qi)的(de)作(zuo)用是(shi)很顯而(er)易見的(de)那(nei)就(jiu)是(shi)換擋(dang)時候由于(yu)動(dong)力輸出端齒(chi)輪(lun)轉速要(yao)快于(yu)馬上要(yao)換入(ru)這個擋(dang)位(wei)的(de)齒(chi)輪(lun)，如果沒有(you)同步器(qi)，把個慢速旋轉的(de)齒(chi)輪(lun)強行塞入(ru)一個高速旋轉的(de)齒(chi)輪(lun)中，肯(ken)定會發(fa)生(sheng)打(da)齒(chi)的(de)現(xian)象(xiang)。
同(tong)步(bu)器(qi)的作用就是(shi)在(zai)換(huan)擋動作發生時，將(jiang)即將(jiang)換(huan)入(ru)擋位的齒(chi)輪轉速提(ti)升至和(he)輸出端(duan)齒(chi)輪速度(du)同(tong)步(bu)的狀態(tai)，這樣換(huan)擋時候(hou)就不會存(cun)在(zai)打齒(chi)現象(xiang)了。
明白了打(da)齒(chi)的(de)現象(xiang)發生，那為什么很(hen)多車正向行(xing)駛時候就(jiu)(jiu)不存在打(da)齒(chi)，而一掛(gua)入(ru)倒(dao)(dao)(dao)擋就(jiu)(jiu)打(da)齒(chi)，那是因(yin)為很(hen)多車型的(de)倒(dao)(dao)(dao)擋是沒(mei)(mei)有安裝(zhuang)倒(dao)(dao)(dao)擋同(tong)(tong)步器的(de)，因(yin)為廠商的(de)理念里(li)，倒(dao)(dao)(dao)擋是需要完全停止再掛(gua)入(ru)并且使用的(de)機會相對小(xiao)了很(hen)多，所以出于(yu)簡化變速(su)箱(xiang)(xiang)結構(gou)和節省成本的(de)目的(de)，很(hen)多中低端手動變速(su)箱(xiang)(xiang)的(de)倒(dao)(dao)(dao)擋就(jiu)(jiu)沒(mei)(mei)有安裝(zhuang)倒(dao)(dao)(dao)擋同(tong)(tong)步器。
沒有(you)安(an)裝倒(dao)(dao)擋(dang)(dang)同(tong)(tong)步(bu)器(qi)的(de)(de)(de)手(shou)動變(bian)速箱就(jiu)(jiu)會存在掛(gua)入(ru)倒(dao)(dao)擋(dang)(dang)打(da)(da)齒(chi)的(de)(de)(de)現象。當(dang)然了，這(zhe)(zhe)里也和用戶使用習慣有(you)非(fei)常大的(de)(de)(de)關(guan)系(xi)，因為倒(dao)(dao)擋(dang)(dang)本身不含(han)同(tong)(tong)步(bu)器(qi)，需要完(wan)全(quan)把車(che)(che)輛停止，讓動力輸出端(duan)速度降低到和倒(dao)(dao)擋(dang)(dang)齒(chi)輪(這(zhe)(zhe)時候倒(dao)(dao)擋(dang)(dang)齒(chi)輪是靜止的(de)(de)(de))之間的(de)(de)(de)轉(zhuan)速差變(bian)小，這(zhe)(zhe)樣才能保(bao)證掛(gua)如倒(dao)(dao)擋(dang)(dang)比較平(ping)順且沒有(you)打(da)(da)齒(chi)。很多用戶車(che)(che)末停穩就(jiu)(jiu)著(zhu)急立刻掛(gua)入(ru)倒(dao)(dao)擋(dang)(dang)，自然會讓沒有(you)同(tong)(tong)步(bu)器(qi)的(de)(de)(de)倒(dao)(dao)擋(dang)(dang)很受(shou)傷，打(da)(da)齒(chi)就(jiu)(jiu)會發生(sheng)。
