連桿體由三部分構(gòu)成，與活塞銷連接的部分稱連桿小頭；與曲軸連接的部分稱連桿大頭，連接小頭與大頭的桿部稱連桿桿身。連桿小頭多為薄壁圓環(huán)形結(jié)構(gòu)，為減少與活塞銷之間的磨損，在小頭孔內(nèi)壓入薄壁青銅襯套。在小頭和襯套上鉆孔或銑槽，以使飛濺的油沫進入潤滑襯套與活塞銷的配合表面。連桿桿身是一個長桿件，湖南PC300連桿生產(chǎn)廠家，在工作中受力也較大，為防止其彎曲變形，桿身必須要具有足夠的剛度。為此，車用發(fā)動機的連桿桿身大都采用Ⅰ形斷面，

連桿的主要損壞形式是疲勞斷裂和過量變形。通常疲勞斷裂的部位是在連桿上的三個高應(yīng)力區(qū)域。連桿的工作條件要求連桿具有較高的強度和抗疲勞性能；又要求具有足夠的鋼性和韌性。傳統(tǒng)連桿加工工藝中其材料一般采用45鋼、40Cr或40MnB等調(diào)質(zhì)鋼，硬度更高，因此，以德國汽車企業(yè)生產(chǎn)的新型連桿材料如C70S6高碳微合金非調(diào)質(zhì)鋼、SPLITASCO系列鍛鋼、FRACTIM鍛鋼和S53CV-FS鍛鋼等(以上均為德國din標(biāo)準(zhǔn))。合金鋼雖具有很**度，但對應(yīng)力集中很敏感。所以，在連桿外形、過度圓角等方面需嚴(yán)格要求，還應(yīng)注意表面加工質(zhì)量以提高疲勞強度，否則**度合金鋼的應(yīng)用并不能達到預(yù)期效果。銷售為一體的企業(yè)，公司位于風(fēng)景優(yōu)美。</p><div
