離合器拔叉簡介

1、保證(zheng)汽(qi)(qi)(qi)(qi)(qi)車(che)平穩(wen)起(qi)(qi)(qi)步 這是(shi)(shi)離(li)(li)合(he)(he)(he)器(qi)的(de)首(shou)要(yao)功能(neng)(neng)。在汽(qi)(qi)(qi)(qi)(qi)車(che)起(qi)(qi)(qi)步前(qian)，自然(ran)(ran)要(yao)先(xian)(xian)起(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)。而(er)汽(qi)(qi)(qi)(qi)(qi)車(che)起(qi)(qi)(qi)步時(shi)(shi)(shi)，汽(qi)(qi)(qi)(qi)(qi)車(che)是(shi)(shi)從(cong)完全靜止(zhi)(zhi)的(de)狀態逐(zhu)步加速(su)的(de)。如(ru)果傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)系(它聯(lian)系著整個汽(qi)(qi)(qi)(qi)(qi)車(che))與(yu)發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)剛性(xing)地聯(lian)系，則變速(su)器(qi)一掛(gua)上檔(dang)，汽(qi)(qi)(qi)(qi)(qi)車(che)將(jiang)突然(ran)(ran)向前(qian)沖一下(xia)，但并不能(neng)(neng)起(qi)(qi)(qi)步。這是(shi)(shi)因為汽(qi)(qi)(qi)(qi)(qi)車(che)從(cong)靜止(zhi)(zhi)到(dao)前(qian)沖時(shi)(shi)(shi)，產(chan)生很大(da)慣性(xing)力(li)，對發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)造成(cheng)很大(da)地阻力(li)矩。在這慣性(xing)阻力(li)矩作用下(xia)，發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)在瞬時(shi)(shi)(shi)間轉速(su)急劇(ju)下(xia)降到(dao)最低穩(wen)定(ding)轉速(su)(一般300-500RPM)以(yi)下(xia)，發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)即熄火而(er)不能(neng)(neng)工作，當然(ran)(ran)汽(qi)(qi)(qi)(qi)(qi)車(che)也(ye)不能(neng)(neng)起(qi)(qi)(qi)步。 因此，我們就需(xu)要(yao)離(li)(li)合(he)(he)(he)器(qi)的(de)幫助了。在發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)起(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)后，汽(qi)(qi)(qi)(qi)(qi)車(che)起(qi)(qi)(qi)步之前(qian)，駕駛員先(xian)(xian)踩下(xia)離(li)(li)合(he)(he)(he)器(qi)踏(ta)板(ban)，將(jiang)離(li)(li)合(he)(he)(he)器(qi)分離(li)(li)，使(shi)發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)和傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)系脫(tuo)開(kai)(kai)，再將(jiang)變速(su)器(qi)掛(gua)上檔(dang)，然(ran)(ran)后逐(zhu)漸(jian)(jian)松開(kai)(kai)離(li)(li)合(he)(he)(he)器(qi)踏(ta)板(ban)，使(shi)離(li)(li)合(he)(he)(he)器(qi)逐(zhu)漸(jian)(jian)接合(he)(he)(he)。在接合(he)(he)(he)過(guo)程中，發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)所受阻力(li)矩逐(zhu)漸(jian)(jian)增大(da)，故(gu)應同時(shi)(shi)(shi)逐(zhu)漸(jian)(jian)踩下(xia)加速(su)踏(ta)板(ban)，即逐(zhu)步增加對發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)的(de)燃料供給(gei)量，使(shi)發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)的(de)轉速(su)始終保持在最低穩(wen)定(ding)轉速(su)上，而(er)不致(zhi)熄火。同時(shi)(shi)(shi)，由于離(li)(li)合(he)(he)(he)器(qi)的(de)接合(he)(he)(he)緊密程度逐(zhu)漸(jian)(jian)增大(da)，發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)經傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)系傳(chuan)給(gei)驅動(dong)(dong)(dong)(dong)(dong)(dong)車(che)輪的(de)轉矩便逐(zhu)漸(jian)(jian)增加，到(dao)牽引力(li)足以(yi)克服起(qi)(qi)(qi)步阻力(li)時(shi)(shi)(shi)，汽(qi)(qi)(qi)(qi)(qi)車(che)即從(cong)靜止(zhi)(zhi)開(kai)(kai)始運動(dong)(dong)(dong)(dong)(dong)(dong)并逐(zhu)步加速(su)

2、保證(zheng)傳(chuan)動(dong)(dong)系換(huan)(huan)檔(dang)(dang)(dang)時工(gong)作(zuo)平順(shun) 2:實現平順(shun)的(de)(de)換(huan)(huan)檔(dang)(dang)(dang) 在汽車(che)行駛過(guo)程中(zhong)，為適應不斷變(bian)化的(de)(de)行駛條件，傳(chuan)動(dong)(dong)系經常要更換(huan)(huan)不同(tong)(tong)檔(dang)(dang)(dang)位工(gong)作(zuo)。實現齒(chi)輪(lun)(lun)式(shi)變(bian)速器(qi)的(de)(de)換(huan)(huan)檔(dang)(dang)(dang)，一(yi)般是撥動(dong)(dong)齒(chi)輪(lun)(lun)或其他掛檔(dang)(dang)(dang)機構，使(shi)原用檔(dang)(dang)(dang)位的(de)(de)某一(yi)齒(chi)輪(lun)(lun)副(fu)(fu)(fu)推出(chu)傳(chuan)動(dong)(dong)，再(zai)使(shi)另一(yi)檔(dang)(dang)(dang)位的(de)(de)齒(chi)輪(lun)(lun)副(fu)(fu)(fu)進入工(gong)作(zuo)。在換(huan)(huan)檔(dang)(dang)(dang)前(qian)必須踩下離(li)合(he)器(qi)踏板，中(zhong)斷動(dong)(dong)力傳(chuan)動(dong)(dong)，便(bian)于(yu)使(shi)原檔(dang)(dang)(dang)位的(de)(de)嚙(nie)合(he)副(fu)(fu)(fu)脫(tuo)開，同(tong)(tong)時使(shi)新檔(dang)(dang)(dang)位嚙(nie)合(he)副(fu)(fu)(fu)的(de)(de)嚙(nie)合(he)部位的(de)(de)速度逐步趨向同(tong)(tong)步，這樣進入嚙(nie)合(he)時的(de)(de)沖擊(ji)可以大(da)大(da)的(de)(de)減(jian)小，實現平順(shun)的(de)(de)換(huan)(huan)檔(dang)(dang)(dang)。

 3、防止傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)系過載 當(dang)汽車進行緊急(ji)制動(dong)(dong)(dong)(dong)(dong)時(shi)，若沒有離合(he)器(qi)(qi)，則發動(dong)(dong)(dong)(dong)(dong)機(ji)將因和傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)系剛性連接而(er)急(ji)劇降低轉速，因而(er)其中(zhong)所有運動(dong)(dong)(dong)(dong)(dong)件將產生很大(da)的(de)慣性力(li)矩(其數值可能大(da)大(da)超過發動(dong)(dong)(dong)(dong)(dong)機(ji)正(zheng)常工作時(shi)所發出的(de)最大(da)扭距)，對(dui)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)系造成超過其承載能力(li)的(de)載荷(he)，而(er)使機(ji)件損壞。有了離合(he)器(qi)(qi)，便可以(yi)依(yi)靠離合(he)器(qi)(qi)主動(dong)(dong)(dong)(dong)(dong)部分(fen)和從動(dong)(dong)(dong)(dong)(dong)部分(fen)之間(jian)可能產生的(de)相對(dui)運動(dong)(dong)(dong)(dong)(dong)以(yi)消除這一危險。因此，我們需要離合(he)器(qi)(qi)來限制傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)系所承受的(de)最大(da)扭距，保證安全。 離合(he)器(qi)(qi)可分(fen)為:摩擦離合(he)器(qi)(qi)，或是(shi)利用液體作為傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)的(de)介質(即(ji)液力(li)偶合(he)器(qi)(qi))，或是(shi)利用磁力(li)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(即(ji)電磁離合(he)器(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。
