離合器拔叉簡介

1、保證汽(qi)(qi)(qi)車(che)(che)(che)(che)(che)平(ping)穩起(qi)(qi)(qi)(qi)步(bu)(bu) 這是(shi)(shi)離(li)(li)合(he)器(qi)的(de)(de)首要功能。在(zai)汽(qi)(qi)(qi)車(che)(che)(che)(che)(che)起(qi)(qi)(qi)(qi)步(bu)(bu)前，自然要先起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機。而(er)汽(qi)(qi)(qi)車(che)(che)(che)(che)(che)起(qi)(qi)(qi)(qi)步(bu)(bu)時(shi)(shi)(shi)，汽(qi)(qi)(qi)車(che)(che)(che)(che)(che)是(shi)(shi)從(cong)(cong)完全靜止(zhi)的(de)(de)狀態逐(zhu)步(bu)(bu)加(jia)(jia)速的(de)(de)。如果傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)系(xi)(它聯系(xi)著整個汽(qi)(qi)(qi)車(che)(che)(che)(che)(che))與發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機剛(gang)性(xing)地(di)聯系(xi)，則變(bian)速器(qi)一(yi)掛上檔(dang)，汽(qi)(qi)(qi)車(che)(che)(che)(che)(che)將(jiang)突然向前沖一(yi)下(xia)，但并不(bu)能起(qi)(qi)(qi)(qi)步(bu)(bu)。這是(shi)(shi)因(yin)(yin)為汽(qi)(qi)(qi)車(che)(che)(che)(che)(che)從(cong)(cong)靜止(zhi)到前沖時(shi)(shi)(shi)，產生很大慣性(xing)力，對發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機造成(cheng)很大地(di)阻力矩。在(zai)這慣性(xing)阻力矩作用(yong)下(xia)，發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機在(zai)瞬時(shi)(shi)(shi)間轉(zhuan)速急(ji)劇(ju)下(xia)降到最(zui)低穩定轉(zhuan)速(一(yi)般300-500RPM)以下(xia)，發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機即(ji)(ji)熄火而(er)不(bu)能工(gong)作，當然汽(qi)(qi)(qi)車(che)(che)(che)(che)(che)也不(bu)能起(qi)(qi)(qi)(qi)步(bu)(bu)。 因(yin)(yin)此，我們就需要離(li)(li)合(he)器(qi)的(de)(de)幫(bang)助了(le)。在(zai)發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)后(hou)，汽(qi)(qi)(qi)車(che)(che)(che)(che)(che)起(qi)(qi)(qi)(qi)步(bu)(bu)之前，駕駛員(yuan)先踩(cai)(cai)下(xia)離(li)(li)合(he)器(qi)踏(ta)(ta)板，將(jiang)離(li)(li)合(he)器(qi)分離(li)(li)，使(shi)發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機和傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)系(xi)脫(tuo)開，再將(jiang)變(bian)速器(qi)掛上檔(dang)，然后(hou)逐(zhu)漸(jian)(jian)松開離(li)(li)合(he)器(qi)踏(ta)(ta)板，使(shi)離(li)(li)合(he)器(qi)逐(zhu)漸(jian)(jian)接(jie)合(he)。在(zai)接(jie)合(he)過程中(zhong)，發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機所受阻力矩逐(zhu)漸(jian)(jian)增大，故應同時(shi)(shi)(shi)逐(zhu)漸(jian)(jian)踩(cai)(cai)下(xia)加(jia)(jia)速踏(ta)(ta)板，即(ji)(ji)逐(zhu)步(bu)(bu)增加(jia)(jia)對發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機的(de)(de)燃(ran)料供給量(liang)，使(shi)發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機的(de)(de)轉(zhuan)速始終保持在(zai)最(zui)低穩定轉(zhuan)速上，而(er)不(bu)致熄火。同時(shi)(shi)(shi)，由于離(li)(li)合(he)器(qi)的(de)(de)接(jie)合(he)緊密程度逐(zhu)漸(jian)(jian)增大，發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機經傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)系(xi)傳給驅動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)車(che)(che)(che)(che)(che)輪的(de)(de)轉(zhuan)矩便逐(zhu)漸(jian)(jian)增加(jia)(jia)，到牽引力足(zu)以克服起(qi)(qi)(qi)(qi)步(bu)(bu)阻力時(shi)(shi)(shi)，汽(qi)(qi)(qi)車(che)(che)(che)(che)(che)即(ji)(ji)從(cong)(cong)靜止(zhi)開始運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)并逐(zhu)步(bu)(bu)加(jia)(jia)速

2、保(bao)證傳動(dong)系(xi)換檔(dang)時(shi)(shi)工(gong)作(zuo)(zuo)平順(shun) 2:實現平順(shun)的(de)換檔(dang) 在汽車行(xing)駛(shi)過程中，為適應不斷變化的(de)行(xing)駛(shi)條件，傳動(dong)系(xi)經常要(yao)更換不同檔(dang)位(wei)工(gong)作(zuo)(zuo)。實現齒輪式變速(su)器(qi)的(de)換檔(dang)，一(yi)般是撥(bo)動(dong)齒輪或其(qi)他掛檔(dang)機構，使(shi)原用檔(dang)位(wei)的(de)某一(yi)齒輪副推(tui)出傳動(dong)，再使(shi)另(ling)一(yi)檔(dang)位(wei)的(de)齒輪副進入工(gong)作(zuo)(zuo)。在換檔(dang)前必須踩下(xia)離合(he)(he)器(qi)踏板，中斷動(dong)力(li)傳動(dong)，便于使(shi)原檔(dang)位(wei)的(de)嚙(nie)合(he)(he)副脫(tuo)開，同時(shi)(shi)使(shi)新(xin)檔(dang)位(wei)嚙(nie)合(he)(he)副的(de)嚙(nie)合(he)(he)部位(wei)的(de)速(su)度(du)逐(zhu)步趨向同步，這樣進入嚙(nie)合(he)(he)時(shi)(shi)的(de)沖擊可以大大的(de)減小，實現平順(shun)的(de)換檔(dang)。

 3、防止(zhi)傳動(dong)(dong)(dong)(dong)系過載(zai) 當汽(qi)車(che)進行緊急制(zhi)動(dong)(dong)(dong)(dong)時(shi)，若沒(mei)有離合(he)器(qi)(qi)(qi)(qi)，則發動(dong)(dong)(dong)(dong)機將因(yin)和傳動(dong)(dong)(dong)(dong)系剛性連(lian)接而急劇降低轉速，因(yin)而其中(zhong)所(suo)有運(yun)動(dong)(dong)(dong)(dong)件將產生很大(da)(da)的(de)(de)慣性力矩(其數值可能大(da)(da)大(da)(da)超(chao)過發動(dong)(dong)(dong)(dong)機正常工作時(shi)所(suo)發出的(de)(de)最大(da)(da)扭距)，對傳動(dong)(dong)(dong)(dong)系造(zao)成超(chao)過其承載(zai)能力的(de)(de)載(zai)荷，而使機件損壞(huai)。有了離合(he)器(qi)(qi)(qi)(qi)，便可以依靠離合(he)器(qi)(qi)(qi)(qi)主動(dong)(dong)(dong)(dong)部(bu)分和從動(dong)(dong)(dong)(dong)部(bu)分之間可能產生的(de)(de)相(xiang)對運(yun)動(dong)(dong)(dong)(dong)以消除這一危險。因(yin)此，我們需要離合(he)器(qi)(qi)(qi)(qi)來限制(zhi)傳動(dong)(dong)(dong)(dong)系所(suo)承受的(de)(de)最大(da)(da)扭距，保證安全。 離合(he)器(qi)(qi)(qi)(qi)可分為:摩擦離合(he)器(qi)(qi)(qi)(qi)，或是利用液體作為傳動(dong)(dong)(dong)(dong)的(de)(de)介質(zhi)(即液力偶合(he)器(qi)(qi)(qi)(qi))，或是利用磁力傳動(dong)(dong)(dong)(dong)(即電(dian)磁離合(he)器(qi)(qi)(qi)(qi)}

離合器撥叉是什么，有什么作用

離合器撥叉是汽車變速箱的一部分，屬于變速箱附件，主要用于離合器換擋。與變速手柄連接，位于手柄下端，撥動中間變速輪改變輸入輸出速比。撥叉一般是指手動變速箱的汽車，位于變速箱和發動機之間的離合器系統中。

踏板通過傳動系統將力傳遞給撥叉，撥叉推動分離軸承壓下離合器壓盤，將發動機和變速箱之間的動力傳遞分離。離合器接合時，踏板處于最高位置，分離桿和分離軸承之間有間隙δ。壓盤在壓緊彈簧的作用下壓緊從動盤，發動機的扭矩通過飛輪和壓盤傳遞到從動盤，再傳遞到變速器的第一軸。

離合器傳遞的最大扭矩取決于從動盤摩擦面的最大靜摩擦力。它與摩擦表面之間的壓力、摩擦面積和摩擦材料的性能有關。對于具有一定結構的離合器，其最大靜摩擦力是一個固定值。如果傳動系統傳遞的扭矩超過這個固定值，離合器就會打滑，從而起到過載保護的作用。
