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)(qi)車的(de)發動(dong)(dong)(dong)(dong)(dong)機(ji)相當(dang)于汽(qi)(qi)車的(de)心臟。發動(dong)(dong)(dong)(dong)(dong)機(ji)故(gu)障也(ye)是困擾車友的(de)問題(ti)，氣門(men)(men)(men)(men)挺(ting)(ting)桿是發動(dong)(dong)(dong)(dong)(dong)機(ji)的(de)重要(yao)(yao)部(bu)件。接下來就讓典邦(bang)給(gei)大(da)家介(jie)紹一下氣門(men)(men)(men)(men)挺(ting)(ting)桿的(de)作用吧(ba)！氣門(men)(men)(men)(men)挺(ting)(ting)桿的(de)功(gong)(gong)能，氣門(men)(men)(men)(men)挺(ting)(ting)桿簡介(jie)-功(gong)(gong)能也(ye)是用于推動(dong)(dong)(dong)(dong)(dong)氣門(men)(men)(men)(men)打開的(de)裝置(zhi)。因為早期發動(dong)(dong)(dong)(dong)(dong)機(ji)中(zhong)使(shi)用的(de)這種裝置(zhi)形狀(zhuang)像(xiang)一根細桿，所以(yi)被(bei)稱為氣門(men)(men)(men)(men)挺(ting)(ting)桿。它的(de)主要(yao)(yao)功(gong)(gong)能是將(jiang)凸(tu)輪(lun)的(de)旋(xuan)轉運動(dong)(dong)(dong)(dong)(dong)轉化(hua)為往復運動(dong)(dong)(dong)(dong)(dong)。但這種結構(gou)的(de)發動(dong)(dong)(dong)(dong)(dong)機(ji)凸(tu)輪(lun)軸一般不布(bu)置(zhi)在(zai)發動(dong)(dong)(dong)(dong)(dong)機(ji)頂部(bu)。隨(sui)著現代汽(qi)(qi)車發動(dong)(dong)(dong)(dong)(dong)機(ji)技(ji)術的(de)發展(zhan)，越(yue)來越(yue)多(duo)的(de)汽(qi)(qi)車發動(dong)(dong)(dong)(dong)(dong)機(ji)采用頂置(zhi)凸(tu)輪(lun)軸結構(gou)，其中(zhong)傳統的(de)長氣門(men)(men)(men)(men)挺(ting)(ting)柱(zhu)(zhu)基本取消，取而代之的(de)是由凸(tu)輪(lun)軸驅動(dong)(dong)(dong)(dong)(dong)的(de)更加緊湊的(de)液壓挺(ting)(ting)柱(zhu)(zhu)，或者凸(tu)輪(lun)軸直接驅動(dong)(dong)(dong)(dong)(dong)氣門(men)(men)(men)(men)搖(yao)臂(bei)來控制氣門(men)(men)(men)(men)的(de)開閉。液壓杠桿主要(yao)(yao)由柱(zhu)(zhu)塞、單(dan)向閥(fa)和單(dan)向閥(fa)彈簧(huang)(huang)組成。液壓桿始終與凸(tu)輪(lun)軸接觸，并且無間(jian)(jian)隙(xi)運行。在(zai)挺(ting)(ting)桿內部(bu)，液壓用于調整(zheng)間(jian)(jian)隙(xi)。液壓挺(ting)(ting)柱(zhu)(zhu)主要(yao)(yao)由柱(zhu)(zhu)塞、單(dan)向閥(fa)和單(dan)向閥(fa)彈簧(huang)(huang)組成。止(zhi)回閥(fa)用于儲存或釋放油。通(tong)過改變挺(ting)(ting)柱(zhu)(zhu)腔內的(de)油壓，可以(yi)改變液壓挺(ting)(ting)柱(zhu)(zhu)的(de)工作長度(du)，從(cong)而自動(dong)(dong)(dong)(dong)(dong)調整(zheng)氣門(men)(men)(men)(men)間(jian)(jian)隙(xi)。
