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

汽車的(de)(de)(de)發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)相當于汽車的(de)(de)(de)心臟。發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)故障也是(shi)(shi)困擾車友的(de)(de)(de)問題，氣(qi)門(men)挺(ting)桿是(shi)(shi)發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)的(de)(de)(de)重要部(bu)(bu)件。接下(xia)來(lai)就讓典邦(bang)給大家介紹一(yi)(yi)下(xia)氣(qi)門(men)挺(ting)桿的(de)(de)(de)作(zuo)用(yong)(yong)(yong)(yong)(yong)吧！氣(qi)門(men)挺(ting)桿的(de)(de)(de)功能(neng)，氣(qi)門(men)挺(ting)桿簡介-功能(neng)也是(shi)(shi)用(yong)(yong)(yong)(yong)(yong)于推(tui)動(dong)(dong)(dong)(dong)(dong)氣(qi)門(men)打開(kai)的(de)(de)(de)裝置(zhi)。因為早期發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)中(zhong)使(shi)用(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)這(zhe)種裝置(zhi)形狀像一(yi)(yi)根細桿，所以被稱為氣(qi)門(men)挺(ting)桿。它(ta)的(de)(de)(de)主要功能(neng)是(shi)(shi)將凸輪(lun)的(de)(de)(de)旋轉(zhuan)運動(dong)(dong)(dong)(dong)(dong)轉(zhuan)化為往復運動(dong)(dong)(dong)(dong)(dong)。但這(zhe)種結構(gou)(gou)的(de)(de)(de)發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)凸輪(lun)軸(zhou)一(yi)(yi)般不布(bu)置(zhi)在(zai)發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)頂(ding)部(bu)(bu)。隨(sui)著(zhu)現代汽車發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)技術的(de)(de)(de)發(fa)展，越來(lai)越多的(de)(de)(de)汽車發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)采(cai)用(yong)(yong)(yong)(yong)(yong)頂(ding)置(zhi)凸輪(lun)軸(zhou)結構(gou)(gou)，其(qi)中(zhong)傳統的(de)(de)(de)長氣(qi)門(men)挺(ting)柱(zhu)(zhu)(zhu)基本取(qu)消，取(qu)而(er)代之的(de)(de)(de)是(shi)(shi)由凸輪(lun)軸(zhou)驅動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)更加緊湊的(de)(de)(de)液(ye)壓(ya)挺(ting)柱(zhu)(zhu)(zhu)，或者凸輪(lun)軸(zhou)直接驅動(dong)(dong)(dong)(dong)(dong)氣(qi)門(men)搖臂(bei)來(lai)控制氣(qi)門(men)的(de)(de)(de)開(kai)閉(bi)。液(ye)壓(ya)杠桿主要由柱(zhu)(zhu)(zhu)塞、單(dan)向(xiang)閥和(he)單(dan)向(xiang)閥彈簧組成。液(ye)壓(ya)桿始終與(yu)凸輪(lun)軸(zhou)接觸，并且無間(jian)隙(xi)(xi)運行(xing)。在(zai)挺(ting)桿內(nei)部(bu)(bu)，液(ye)壓(ya)用(yong)(yong)(yong)(yong)(yong)于調整(zheng)間(jian)隙(xi)(xi)。液(ye)壓(ya)挺(ting)柱(zhu)(zhu)(zhu)主要由柱(zhu)(zhu)(zhu)塞、單(dan)向(xiang)閥和(he)單(dan)向(xiang)閥彈簧組成。止回閥用(yong)(yong)(yong)(yong)(yong)于儲(chu)存或釋放(fang)油(you)。通過改變挺(ting)柱(zhu)(zhu)(zhu)腔(qiang)內(nei)的(de)(de)(de)油(you)壓(ya)，可以改變液(ye)壓(ya)挺(ting)柱(zhu)(zhu)(zhu)的(de)(de)(de)工(gong)作(zuo)長度，從(cong)而(er)自(zi)動(dong)(dong)(dong)(dong)(dong)調整(zheng)氣(qi)門(men)間(jian)隙(xi)(xi)。
