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)(de)發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機相當于(yu)汽車的(de)(de)(de)(de)心臟。發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機故(gu)障也(ye)是(shi)(shi)困擾車友的(de)(de)(de)(de)問題，氣門(men)(men)(men)挺(ting)(ting)桿是(shi)(shi)發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機的(de)(de)(de)(de)重(zhong)要(yao)部件。接下來就讓典邦給大家介紹一(yi)下氣門(men)(men)(men)挺(ting)(ting)桿的(de)(de)(de)(de)作用(yong)(yong)吧！氣門(men)(men)(men)挺(ting)(ting)桿的(de)(de)(de)(de)功(gong)能，氣門(men)(men)(men)挺(ting)(ting)桿簡介-功(gong)能也(ye)是(shi)(shi)用(yong)(yong)于(yu)推(tui)動(dong)(dong)(dong)(dong)(dong)氣門(men)(men)(men)打開(kai)的(de)(de)(de)(de)裝(zhuang)置(zhi)(zhi)。因(yin)為早期發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機中使用(yong)(yong)的(de)(de)(de)(de)這種裝(zhuang)置(zhi)(zhi)形狀像一(yi)根細桿，所以被稱(cheng)為氣門(men)(men)(men)挺(ting)(ting)桿。它的(de)(de)(de)(de)主要(yao)功(gong)能是(shi)(shi)將凸(tu)(tu)(tu)輪(lun)(lun)的(de)(de)(de)(de)旋轉(zhuan)運(yun)動(dong)(dong)(dong)(dong)(dong)轉(zhuan)化(hua)為往(wang)復(fu)運(yun)動(dong)(dong)(dong)(dong)(dong)。但這種結構(gou)(gou)的(de)(de)(de)(de)發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機凸(tu)(tu)(tu)輪(lun)(lun)軸(zhou)一(yi)般不布置(zhi)(zhi)在發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機頂部。隨著(zhu)現代(dai)汽車發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機技術的(de)(de)(de)(de)發(fa)(fa)展，越來越多的(de)(de)(de)(de)汽車發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機采用(yong)(yong)頂置(zhi)(zhi)凸(tu)(tu)(tu)輪(lun)(lun)軸(zhou)結構(gou)(gou)，其中傳統的(de)(de)(de)(de)長氣門(men)(men)(men)挺(ting)(ting)柱(zhu)基本取(qu)消，取(qu)而代(dai)之的(de)(de)(de)(de)是(shi)(shi)由(you)凸(tu)(tu)(tu)輪(lun)(lun)軸(zhou)驅動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)(de)更加緊湊的(de)(de)(de)(de)液(ye)(ye)(ye)壓(ya)(ya)挺(ting)(ting)柱(zhu)，或者凸(tu)(tu)(tu)輪(lun)(lun)軸(zhou)直(zhi)接驅動(dong)(dong)(dong)(dong)(dong)氣門(men)(men)(men)搖(yao)臂來控制氣門(men)(men)(men)的(de)(de)(de)(de)開(kai)閉。液(ye)(ye)(ye)壓(ya)(ya)杠桿主要(yao)由(you)柱(zhu)塞(sai)、單(dan)向閥和單(dan)向閥彈簧組(zu)成。液(ye)(ye)(ye)壓(ya)(ya)桿始終與凸(tu)(tu)(tu)輪(lun)(lun)軸(zhou)接觸，并且無間(jian)隙(xi)運(yun)行。在挺(ting)(ting)桿內(nei)部，液(ye)(ye)(ye)壓(ya)(ya)用(yong)(yong)于(yu)調(diao)(diao)整間(jian)隙(xi)。液(ye)(ye)(ye)壓(ya)(ya)挺(ting)(ting)柱(zhu)主要(yao)由(you)柱(zhu)塞(sai)、單(dan)向閥和單(dan)向閥彈簧組(zu)成。止回閥用(yong)(yong)于(yu)儲存或釋放(fang)油。通過改變挺(ting)(ting)柱(zhu)腔內(nei)的(de)(de)(de)(de)油壓(ya)(ya)，可以改變液(ye)(ye)(ye)壓(ya)(ya)挺(ting)(ting)柱(zhu)的(de)(de)(de)(de)工作長度，從(cong)而自動(dong)(dong)(dong)(dong)(dong)調(diao)(diao)整氣門(men)(men)(men)間(jian)隙(xi)。
