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。

汽(qi)(qi)車的(de)(de)發(fa)(fa)動(dong)(dong)(dong)(dong)機相當于(yu)汽(qi)(qi)車的(de)(de)心臟。發(fa)(fa)動(dong)(dong)(dong)(dong)機故障也是(shi)困擾(rao)車友的(de)(de)問(wen)題，氣(qi)(qi)(qi)門(men)挺(ting)(ting)桿是(shi)發(fa)(fa)動(dong)(dong)(dong)(dong)機的(de)(de)重要部件。接下來(lai)就讓(rang)典邦給大家介紹一下氣(qi)(qi)(qi)門(men)挺(ting)(ting)桿的(de)(de)作用(yong)吧！氣(qi)(qi)(qi)門(men)挺(ting)(ting)桿的(de)(de)功(gong)能(neng)，氣(qi)(qi)(qi)門(men)挺(ting)(ting)桿簡介-功(gong)能(neng)也是(shi)用(yong)于(yu)推動(dong)(dong)(dong)(dong)氣(qi)(qi)(qi)門(men)打(da)開(kai)的(de)(de)裝(zhuang)(zhuang)置(zhi)(zhi)。因(yin)為早期發(fa)(fa)動(dong)(dong)(dong)(dong)機中使(shi)用(yong)的(de)(de)這(zhe)種裝(zhuang)(zhuang)置(zhi)(zhi)形狀(zhuang)像一根細桿，所以被稱為氣(qi)(qi)(qi)門(men)挺(ting)(ting)桿。它(ta)的(de)(de)主(zhu)要功(gong)能(neng)是(shi)將(jiang)凸(tu)輪(lun)的(de)(de)旋轉運(yun)動(dong)(dong)(dong)(dong)轉化為往復運(yun)動(dong)(dong)(dong)(dong)。但(dan)這(zhe)種結構(gou)的(de)(de)發(fa)(fa)動(dong)(dong)(dong)(dong)機凸(tu)輪(lun)軸(zhou)一般(ban)不布置(zhi)(zhi)在發(fa)(fa)動(dong)(dong)(dong)(dong)機頂部。隨著(zhu)現代汽(qi)(qi)車發(fa)(fa)動(dong)(dong)(dong)(dong)機技術(shu)的(de)(de)發(fa)(fa)展，越來(lai)越多的(de)(de)汽(qi)(qi)車發(fa)(fa)動(dong)(dong)(dong)(dong)機采用(yong)頂置(zhi)(zhi)凸(tu)輪(lun)軸(zhou)結構(gou)，其中傳統的(de)(de)長氣(qi)(qi)(qi)門(men)挺(ting)(ting)柱(zhu)基本取消，取而代之的(de)(de)是(shi)由(you)凸(tu)輪(lun)軸(zhou)驅(qu)動(dong)(dong)(dong)(dong)的(de)(de)更(geng)加(jia)緊(jin)湊(cou)的(de)(de)液壓(ya)(ya)(ya)(ya)挺(ting)(ting)柱(zhu)，或(huo)者凸(tu)輪(lun)軸(zhou)直接驅(qu)動(dong)(dong)(dong)(dong)氣(qi)(qi)(qi)門(men)搖(yao)臂來(lai)控制氣(qi)(qi)(qi)門(men)的(de)(de)開(kai)閉(bi)。液壓(ya)(ya)(ya)(ya)杠桿主(zhu)要由(you)柱(zhu)塞(sai)、單向(xiang)閥(fa)(fa)和單向(xiang)閥(fa)(fa)彈簧(huang)組成(cheng)。液壓(ya)(ya)(ya)(ya)桿始(shi)終(zhong)與凸(tu)輪(lun)軸(zhou)接觸，并且無間隙運(yun)行(xing)。在挺(ting)(ting)桿內部，液壓(ya)(ya)(ya)(ya)用(yong)于(yu)調(diao)整間隙。液壓(ya)(ya)(ya)(ya)挺(ting)(ting)柱(zhu)主(zhu)要由(you)柱(zhu)塞(sai)、單向(xiang)閥(fa)(fa)和單向(xiang)閥(fa)(fa)彈簧(huang)組成(cheng)。止回閥(fa)(fa)用(yong)于(yu)儲存(cun)或(huo)釋放油。通過改(gai)變挺(ting)(ting)柱(zhu)腔內的(de)(de)油壓(ya)(ya)(ya)(ya)，可以改(gai)變液壓(ya)(ya)(ya)(ya)挺(ting)(ting)柱(zhu)的(de)(de)工(gong)作長度(du)，從而自(zi)動(dong)(dong)(dong)(dong)調(diao)整氣(qi)(qi)(qi)門(men)間隙。
