Description

用于车辆的液压悬置
技术领域
本公开涉及一种用于车辆的液压悬置，且更特别地，涉及一种能够分散和去除车辆的震颤噪声的用于车辆的液压悬置。
背景技术
车辆动力传动系通常包括发动机和变速器。动力传动系可以通过发动机悬置、变速器悬置等安装在车辆的发动机室中，以减少车身中的振动和噪声。例如，流体密封式悬置或液压悬置广泛地用于密封绝缘体(例如橡胶)下部上的流体，并且可同时降低高频范围振动和低频范围振动。
此处，以下将参照附图1和附图2描述常规的液压悬置。
如图1和图2所示，附图标记10表示与发动机联接的螺栓。螺栓10与芯套12联接，并且芯套12的外径部通过硫化粘合等方法形成有主橡胶14。
此外，主橡胶14的下部定位有上部板16和下部板18彼此联接的孔口部20，并且孔口部20的下部安装有以螺栓等作为介质而联接到车身的下部橡胶膜片28。
在这种情况下，下部板18在其上表面部上形成有凹槽结构的流体路径18-1，并且同时被制成具有形成在流体路径18-1的预定位置上的下部入口及出口的环形形状；并且上部板16通过具有上部入口及出口16-1的环形板体制成，以覆盖下部板18的流体路径18-1并与其联接。
孔口部20的中心部安装有橡胶材料的隔膜26，其分隔上部流体室22和下部流体室24。具体地，隔膜26位于孔口部20的中央开口部上，同时被容置在台阶部18-3中，使得隔膜26的外径部形成在下部板18的内径部上，然后成为被上部板16的内圆周端覆盖的状态。
在这种情况下，作为允许上部流体室22和下部流体室24之间的流体运动的第二孔口的喷嘴部30形成在隔膜26的外径部与上部板16和下部板18的内径部之间。因此，当较大的位移振动(例如，在崎岖不平的道路上行驶)输入到按上述方式配置的液压悬置时，如附图2的右侧所示，主橡胶14受到压缩，同时喷嘴部30通过按压隔膜26而变成关闭状态；同时，当上部流体室22内的流体通过形成在孔口部20的上部板16上的上部入口及出口16-1进入下部板18的流体路径18-1，然后通过形成在流体路径的预定位置上的下部入口及出口18-2填充到下部流体室24中时，实现了吸收较大的位移振动的高减振。
另一方面，当较小的位移振动(例如，在平稳道路上行驶)输入到液压悬置时，如附图2的左侧所示，上部流体室22的流体在通过喷嘴部30向下部流体室24侧移动的同时吸收较小的位移振动，从而获得改善的噪声、振动和平顺性(NVH)效果。
然而，如附图3所示，当在液压悬置上发生刺激时，在每个流体室的内部压力变化的同时隔膜26受到刺激，并且由于喷嘴部30的撞击而出现噪声。同时，隔膜26根据隔膜的刺激反复经受拉伸和压缩。
本背景技术部分中公开的上述信息仅用于增强对本公开背景的理解，因此可能包含不构成相关技术的信息。
发明内容
提出本公开以解决上述问题。本公开的目的是提供一种用于车辆的液压悬置，其能够应用具有重复形成的峰和谷的如圆筒形结构的隔膜来分开刺激的方向并使隔膜在不同的方向上移动。液压悬置使喷嘴在隔膜上的碰撞延迟以减少震颤噪声，依次使隔膜的峰和谷与喷嘴板接触，并分散和/或去除震颤噪声。
根据本公开的实施例，一种液压悬置包括：联接到螺栓的芯套；形成在芯套的外表面上的主橡胶；联接到主橡胶的下部以分隔上部流体室和下部流体室的孔口部；以及联接到孔口部的下部的下部橡胶膜片。孔口部包括形成有第一流体入口及出口的上部喷嘴板、形成有流体路径和第二流体入口及出口的下部喷嘴板以及垂直设置在上部喷嘴板和下部喷嘴板之间的圆筒形隔膜，并且峰和谷的布置沿隔膜的圆周形成，峰和谷的布置选择性地接触上部喷嘴板和下部喷嘴板。
上部喷嘴板可包括环形水平板，并且第一流体入口及出口以及垂直管可形成在水平板的内径部上并通过下部喷嘴板支撑。
垂直管可沿其圆周以均匀的间隔形成有多个第一流体通孔。
流体路径可形成在下部喷嘴板的上表面的外圆周上，第二流体入口及出口可形成在流体路径的预定位置上，并且第二流体通孔可沿下部喷嘴板的上表面的内圆周重复地形成，第二流体通孔垂直地贯穿上部喷嘴板支撑表面。
垂直管与下部喷嘴板的内径部之间的距离可形成为大于隔膜的厚度。
水平板与下部喷嘴板的底板之间的距离可形成为大于隔膜的高度。
因此，本公开提供至少以下的效果。
首先，可以应用将液压悬置的上部流体室和下部流体室进行分隔的如圆筒形结构的具有重复形成的峰和谷的布置的孔口部的隔膜来使隔膜的运动方向垂直于在液压悬置上操作的刺激方向，从而在隔膜运动时延迟喷嘴板的任何撞击，以减少由于撞击而引起的震颤噪声。
其次，可以根据隔膜的运动使隔膜的峰和谷布置的部分依次接触，从而分散在隔膜与喷嘴板接触的情况下发生的碰撞以消除震颤噪声。
以下讨论本公开的其它方面和实施例。

在下文中，将参照附图描述本公开的实施例。
如图6所示，根据本公开的实施例的液压悬置包括：与连接到发动机的螺栓10联接的芯套12；通过硫化粘合等方法在芯套12的外径部上形成的主橡胶14；联接到主橡胶14的下部以分隔上部流体室22和下部流体室24的孔口部100；以及固定在孔口部100的下部以使用螺栓等作为介质而连接到车身的下部橡胶膜片28。
特别地，如图4和图5所示，孔口部100包括形成有第一流体入口及出口112的上部喷嘴板110；形成有流体路径121和第二流体入口及出口123的下部喷嘴板120；以及垂直设置在上部喷嘴板110与下部喷嘴板120之间的圆筒型隔膜130。
上部喷嘴板110包括环状水平板111和在水平板111的内径部向下弯曲并支撑在下部喷嘴板120的底板上的垂直管113。
此外，第一流体入口及出口112贯穿水平板111的预定位置并形成在水平板111的预定位置上；并且垂直管113沿其圆周均匀地形成有多个第一流体通孔114。
在这种情况下，第一流体入口及出口112垂直地贯穿并形成；并且第一流体通孔114水平地贯穿并形成。
下部喷嘴板120具有圆形的板体形状，并且在其上表面的外圆周部的位置上设置有形成有凹形流体路径121和孔形第二流体入口及出口123的结构。
更具体地，下部喷嘴板120的上表面的外圆周部凹入地形成有流体沿其圆周流动的流体路径121；流体路径121的预定位置垂直地贯穿第二流体入口及出口123并形成有第二流体入口及出口123；并且与第二流体入口及出口123相邻的位置形成有将沿流体路径121流动的流体引导向第二流体入口及出口123的分隔壁122。
此外，下部喷嘴板120的上表面的内圆周部沿其圆周重复地形成有垂直地贯穿上部喷嘴板支撑表面124的第二流体通孔125。
隔膜130在上部喷嘴板110和下部喷嘴板120之间形成间隙，即流体可通过的孔口形间隙，并且可移动地置于上部喷嘴板110和下部喷嘴板120之间。
特别地，隔膜130设置成圆柱形，并且沿其圆周形成有峰和谷的布置。峰和谷的布置可选择性地接触上部喷嘴板110和下部喷嘴板120。
再次参照图6，如上所述，具有置于上部喷嘴板110和下部喷嘴板120之间的隔膜130的孔口部100安装在主橡胶14的下部与下部橡胶膜片28的上部之间。
如图7和图8所示，隔膜130置于上部喷嘴板110和下部喷嘴板120之间。隔膜130被定位成接触上部喷嘴板110的垂直管113的外径部和下部喷嘴板120的内径部。
更具体地，隔膜130的峰131与上部喷嘴板110的垂直管113的外径部间隔开，并被设置成向外凸出的状态，同时被设置成可与下部喷嘴板120的内径部接触的状态；并且隔膜的谷132与下部喷嘴板120的内径部间隔开，并被设置成向内凸出的状态，同时被设置成可与上部喷嘴板110的垂直管113的外径部接触的状态。
同时，为了确保隔膜130的流动性，隔膜130被设置成其尺寸小于置于上部喷嘴板110和下部喷嘴板120之间的空间。
为此，如图9所示，通过将上部喷嘴板110的垂直管113和下部喷嘴板120的内径部之间的宽度(d1)形成为大于隔膜130的厚度(d2)，并且将上部喷嘴板110的水平板111与下部喷嘴板120的底板之间的高度(D1)形成为大于隔膜130的高度(D2)，隔膜130可变成可移动地定位在置于上部喷嘴板110和下部喷嘴板120之间的空间中的状态，并且隔膜130可在压缩之前的时间保持原始形状或者通过流体压力保持张力。
因此，当较大的位移振动(例如，由于在起伏不平的道路上驾驶车辆)输入到具有该结构的液压悬置中时，如图10所示，在上部流体室22内的流体通过形成在上部喷嘴板110的水平板111上的第一流体入口及出口112进入下部喷嘴板120的流体路径121，然后通过形成在流体路径121的预定位置上的第二流体入口及出口123而填充到下部流体室24中的同时，实现了吸收较大的位移振动的高减振。
在这种情况下，因为在输入较大的位移振动时，上部流体室22内的流体在垂直刺激时不直接作用在隔膜130上，而是穿过垂直于刺激方向的径向上存在的垂直管113的第一流体通孔114，然后作用在隔膜130上，所以可以在隔膜130移动的同时延迟撞击下部喷嘴板120的内径表面，从而减少在隔膜撞击喷嘴板的情况下出现的震颤噪声。
此外，发生隔膜130受从上部流体室22朝向下部流体室24的流体压力而压缩的运动，或者隔膜130受从下部流体室24朝向上部流体室22的流体压力而拉伸的运动等，并且如附图12所示，隔膜130的峰131和谷132的部分依次与上部喷嘴板或下部喷嘴板接触，从而分散隔膜130与上部喷嘴板或下部喷嘴板接触的情况下发生的碰撞，以进一步减少震颤噪声。
另一方面，当较小的位移振动(例如，由于怠速振动或者在平稳道路上驾驶车辆)输入到液压悬置时，如图11所示，在上部流体室22内的流体穿过上部喷嘴板110与隔膜130之间的间隙以及隔膜130与下部喷嘴板120之间的间隙，然后通过下部喷嘴板120的第二流体通孔125流入到下部流体室24的同时，可以吸收较小的位移振动，从而改善噪声、振动和平顺性(NVH)特性。
已经参考本公开的某些实施例详细描述了本公开。然而，本领域技术人员应当理解，在不脱离本公开的原理和精神的情况下，可以对这些实施例进行改变，本公开的范围在所附权利要求及其等同物中限定。
