氣門挺桿簡介

氣門挺桿。氣門挺桿的作用如下：

1、為了保證氣門關閉嚴密，會在氣門桿端與氣門驅動件之間留有適當的間隙，稱為氣門間隙；

2、若氣門間隙調整不當就會使發動機運行不正常的，過大會影響氣門的開啟量，氣門升程減少引起進氣不足，排氣不徹底，過小會引起氣門關閉不嚴引起漏氣，造成動力下降；

3、所以為了避免氣門間隙調整不當引起的麻煩，一般高速發動機上都會使用可自行調整氣門間隙的液力挺桿。

氣門挺桿的作用

汽(qi)車的(de)(de)發(fa)動(dong)(dong)(dong)機(ji)相當于(yu)汽(qi)車的(de)(de)心臟(zang)。發(fa)動(dong)(dong)(dong)機(ji)故障也是(shi)(shi)困擾車友的(de)(de)問題，氣(qi)(qi)(qi)門(men)挺(ting)(ting)桿(gan)是(shi)(shi)發(fa)動(dong)(dong)(dong)機(ji)的(de)(de)重(zhong)要部件。接下來就讓典邦(bang)給大家介(jie)紹一(yi)下氣(qi)(qi)(qi)門(men)挺(ting)(ting)桿(gan)的(de)(de)作用(yong)(yong)(yong)吧！氣(qi)(qi)(qi)門(men)挺(ting)(ting)桿(gan)的(de)(de)功(gong)能(neng)(neng)，氣(qi)(qi)(qi)門(men)挺(ting)(ting)桿(gan)簡介(jie)-功(gong)能(neng)(neng)也是(shi)(shi)用(yong)(yong)(yong)于(yu)推動(dong)(dong)(dong)氣(qi)(qi)(qi)門(men)打(da)開的(de)(de)裝(zhuang)置(zhi)(zhi)。因為(wei)(wei)早期發(fa)動(dong)(dong)(dong)機(ji)中(zhong)使用(yong)(yong)(yong)的(de)(de)這(zhe)種(zhong)(zhong)裝(zhuang)置(zhi)(zhi)形狀像一(yi)根細桿(gan)，所(suo)以(yi)被稱為(wei)(wei)氣(qi)(qi)(qi)門(men)挺(ting)(ting)桿(gan)。它的(de)(de)主要功(gong)能(neng)(neng)是(shi)(shi)將(jiang)凸(tu)輪(lun)的(de)(de)旋轉運(yun)動(dong)(dong)(dong)轉化為(wei)(wei)往復運(yun)動(dong)(dong)(dong)。但這(zhe)種(zhong)(zhong)結構的(de)(de)發(fa)動(dong)(dong)(dong)機(ji)凸(tu)輪(lun)軸(zhou)(zhou)一(yi)般不布置(zhi)(zhi)在發(fa)動(dong)(dong)(dong)機(ji)頂部。隨著現代汽(qi)車發(fa)動(dong)(dong)(dong)機(ji)技術的(de)(de)發(fa)展，越來越多的(de)(de)汽(qi)車發(fa)動(dong)(dong)(dong)機(ji)采(cai)用(yong)(yong)(yong)頂置(zhi)(zhi)凸(tu)輪(lun)軸(zhou)(zhou)結構，其中(zhong)傳統(tong)的(de)(de)長(chang)氣(qi)(qi)(qi)門(men)挺(ting)(ting)柱(zhu)(zhu)基本取(qu)消，取(qu)而代之的(de)(de)是(shi)(shi)由(you)凸(tu)輪(lun)軸(zhou)(zhou)驅動(dong)(dong)(dong)的(de)(de)更加緊湊(cou)的(de)(de)液(ye)(ye)(ye)壓(ya)挺(ting)(ting)柱(zhu)(zhu)，或者凸(tu)輪(lun)軸(zhou)(zhou)直接驅動(dong)(dong)(dong)氣(qi)(qi)(qi)門(men)搖臂來控制氣(qi)(qi)(qi)門(men)的(de)(de)開閉。液(ye)(ye)(ye)壓(ya)杠桿(gan)主要由(you)柱(zhu)(zhu)塞(sai)、單向(xiang)閥(fa)(fa)(fa)和單向(xiang)閥(fa)(fa)(fa)彈(dan)簧(huang)組(zu)成。液(ye)(ye)(ye)壓(ya)桿(gan)始終與凸(tu)輪(lun)軸(zhou)(zhou)接觸，并且無間隙(xi)(xi)(xi)運(yun)行。在挺(ting)(ting)桿(gan)內(nei)部，液(ye)(ye)(ye)壓(ya)用(yong)(yong)(yong)于(yu)調整間隙(xi)(xi)(xi)。液(ye)(ye)(ye)壓(ya)挺(ting)(ting)柱(zhu)(zhu)主要由(you)柱(zhu)(zhu)塞(sai)、單向(xiang)閥(fa)(fa)(fa)和單向(xiang)閥(fa)(fa)(fa)彈(dan)簧(huang)組(zu)成。止回閥(fa)(fa)(fa)用(yong)(yong)(yong)于(yu)儲存或釋放油(you)。通過(guo)改(gai)變(bian)挺(ting)(ting)柱(zhu)(zhu)腔(qiang)內(nei)的(de)(de)油(you)壓(ya)，可(ke)以(yi)改(gai)變(bian)液(ye)(ye)(ye)壓(ya)挺(ting)(ting)柱(zhu)(zhu)的(de)(de)工作長(chang)度，從而自(zi)動(dong)(dong)(dong)調整氣(qi)(qi)(qi)門(men)間隙(xi)(xi)(xi)。
