Description
一种新型支臂压入式悬置
技术领域
[0001] 本实用新型涉及动力总成悬置系统减振领域，特别是涉及一种新型支臂压入式悬置。
背景技术
[0002] 动力总成悬置系统振动是汽车整车振动的一部分，它对车身振动和车室内噪声水 平都有较大的影响，悬置系统设计的好坏将直接影响到整车的振动噪声水平，是影响乘坐 舒适性的重要因素。汽车动力总成悬置系统的主要振动来源是工作过程中其自身产生的往 复不平衡惯性力和力矩波动，另外汽车在各种路面上行驶，由于路面不平度引起的振动激 励也会与动力总成悬置系统产生影响。因此汽车动力总成悬置系统的主要作用可以分为两 个方面，即：降低动力总成振动向车身的传递和控制动力总成位移。
[0003] 人们还进行了长期的探索，发明了纯胶悬置、液压悬置、空气悬置。这些都能起到 降低动力总成振动向车身的传递和控制动力总成位移的作用。但要把悬置和动力总成连接 起来还得用到支臂（支架）。因此支臂和悬置连接方式也在不断改进和优化。其中支臂压 入式连接较为常用。
[0004] 常规支臂压入连接（如图1)是通过橡胶过盈配合装配，是面与面的接触，完全靠 橡胶的摩擦力来固定支臂。这样常规支臂压入的装配方式，压入力和拔出力基本相等。如 果压入力过大，其内骨架容易破坏变形。因此常规支臂压入连接方式存在一定的风险和局 限性。
发明内容
[0005] 本实用新型所要解决的技术问题是提供一种新型支臂压入悬置，用于解决支臂压 入悬置存在的风险和使用局限性，使得支臂压入悬置能得到广泛可靠的应用。
[0006] 本实用新型解决其技术问题所采用的技术方案是：提供一种新型支臂压入式悬 置，包括外壳体、内骨架、弹性主簧、支臂和底座，所述的支臂在与弹性主簧的过盈面上设有 锯齿结构；所述的锯齿结构与所述的弹性主簧过盈配合；所述的弹性主簧与内骨架硫化固 定，其中，所述的内骨架位于弹性主簧与支臂的过盈面处，并与所述的支臂过盈配合；所述 的外壳体和底座相互连接，并位于所述的弹性主簧的外围。
[0007] 所述的新型支臂压入式悬置的外壳体和底座通过铆接装配固定。
[0008] 所述的新型支臂压入式悬置的外壳体和底座均由铝材料制成。
[0009] 所述的新型支臂压入式悬置的内骨架由金属材料制成。
[0010] 所述的新型支臂压入式悬置的弹性主簧由橡胶材料制成。
[0011] 有益效果
[0012] 由于采用了上述的技术方案，本实用新型与现有技术相比，具有以下的优点和积 极效果：本实用新型在支臂与橡胶过盈的面上增加锯齿，通过锯齿与橡胶面的过盈配合，不 仅提高了橡胶的摩擦力，还增加了橡胶的拉力，这样就使得拔出力远远大于压入力，避免了使用局限性，加大支臂压入悬置的使用范围，与此同时还提高了支臂压入悬置安全性和可 靠性。本实用新型工艺容易实现，大大减小工人的劳动时间，提高了工作效率，还可以在可 以在高温条件下通过路谱模拟道路试验，以及碰撞，强化路试等各种试验。
附图说明
[0013] 图1是现有技术中支臂压入悬置左剖视图；
[0014] 图2是本实用新型的左剖视图；
[0015] 图3是本实用新型的三轴视图。
具体实施方式
[0016] 下面结合具体实施例，进一步阐述本实用新型。应理解，这些实施例仅用于说明本 实用新型而不用于限制本实用新型的范围。此外应理解，在阅读了本实用新型讲授的内容 之后，本领域技术人员可以对本实用新型作各种改动或修改，这些等价形式同样落于本申 请所附权利要求书所限定的范围。
[0017] 本实用新型的实施方式涉及一种新型支臂压入悬置，如图2和图3所示，包括外壳 体1、内骨架2、弹性主簧4、支臂3和底座5，所述的支臂3在与弹性主簧4的过盈面上设有 锯齿结构；所述的锯齿结构与所述的弹性主簧4过盈配合；所述的弹性主簧4与内骨架2硫 化固定，其中，所述的内骨架2位于弹性主簧4与支臂3的过盈面处，并与所述的支臂3过盈 配合；所述的外壳体1和底座5通过铆接装配固定连接，并位于所述的弹性主簧4的外围。 其中，外壳体1和底座5均由铝材料制成，弹性主簧4由橡胶材料制成，内骨架2由金属材 料制成。在使用时，将支臂3通过螺栓与发动机相连，外壳体1和底座5固定后与通过螺栓 与车身相连。
[0018] 不难发现，本实用新型在大振幅下具有较好的阻尼特性，在小振幅下具有较优的 解耦特性，可满足悬置系统整车NVH特性要求。由于在支臂与橡胶过盈的面上增加锯齿，通 过锯齿与橡胶面的过盈配合，不仅提高了橡胶的摩擦力，还增加了橡胶的拉力，这样就使得 拔出力远远大于压入力，大大提高支臂压入悬置的安全性和可靠性。
