本申请要求于2017年9月1日提交的申请号为10-2017-0111999的韩国专利申请的优先权，其公开内容通过引用并入本文。
技术领域
本发明涉及一种用于改善行驶性能的具有连续可变特性的液力支座，更具体地，涉及一种用于改善行驶性能的具有连续可变特性的液力支座，其中自动流体打开和关闭单元安装在上流体腔和下流体腔之间。
背景技术
近来，为了根据行驶条件来改变车辆的特性，已经开发了各种类型的发动机支座，诸如半主动式支座、主动式支座等。其中，已经开发出具有如下结构的磁流变液力(MRF)支座：MR流体被施加到与普通液压式支座相似结构的内部，并且流体的剪切应力根据施加到流体的磁场的强度而变化。因此，安装特性可以被改变，并且因此噪音、振动和不平顺性(NVH)以及SS性能可以得到改善。
与普通半主动式支座相比，上述MRF支座的优点在于MRF支座的特性可以与输入到MRF支座的电流强度成比例地连续变化。由于半主动式支座被构造成使得其特性通过分步法来实现，且主动式支座不是适于提高其动态特性的系统，所以这些支座都难以改善SS性能。
此外，MRF支座可持续地察觉到动态特性以调整这种动态特性，因此，不会检测到车辆中的振动(冲击)的变化。然而，因为MRF支座比普通主动式支座更昂贵，所以MRF支座很大的缺点是成本高。因此，本发明提出了一种液力支座，该液力支座根据行驶状况具有连续可变特性，并且具有与半主动式支座相当的成本。
发明内容
因此，本发明提供了一种用于改善行驶性能的具有连续可变特性的液力支座，其中自动流体打开和关闭单元安装在上流体腔和下流体腔之间，以便保持常规MRF支座的优点诸如连续支座特性变化和动态特性上升的可变性，并具有与常规MRF支座相同的特性。
本发明待实现的技术目的不限于上面提到的技术目的，并且本领域技术人员可以从以下给出的描述中清楚地理解其它目的。
根据本发明的一个方面，用于改善行驶性能的具有连续可变特性的液力支座可以包括：芯部，具有与发动机接合并且插入至芯部的中央部分的中央螺栓；橡胶构件，形成在芯部的外周表面上，芯部和橡胶构件设置在支架外壳中；上流体腔，与芯部和橡胶构件接触以密封上流体腔中的流体；下流体腔，设置在上流体腔的下方以密封下流体腔中的流体；以及自动流体打开和关闭单元，安装在上流体腔和下流体腔之间，以通过电流变化连续地打开和关闭流动路径。
自动流体打开和关闭单元可以包括：轭部(yoke)，具有主体，该主体具有敞开的上表面和形成在主体中的容纳空间，和线圈固定板，该线圈固定板设置在容纳空间的下部区域中并且具有缠绕在线圈固定板上的线圈；以及柱塞，安装在轭部的容纳空间(例如，空腔)内，具有多个流体孔径并且被配置成通过线圈的磁力在容纳空间内竖直地移动。

另外，在本发明的说明书和权利要求书中使用的术语或词语不应被解释为具有典型的或词典的含义，而是基于发明人可以适当地定义术语的概念以最佳方式解释本发明的原则应被解释为具有符合本发明的技术精神的含义和概念。
将参照附图详细描述本发明的示例性实施例。如图1中示例性所示，根据本发明的用于改善行驶性能的具有连续可变特性的液力支座可以包括：芯部10，具有与发动机接合并插入芯部10的中央部分中的中央螺栓11；橡胶构件30，形成在芯部10的外周表面上，芯部10和橡胶构件30设置在支架外壳20中；上流体腔40，与芯部10和橡胶构件30接触以密封上流体腔40中的流体；下流体腔50，设置在上流体腔40的下方以密封下流体腔50中的流体；以及膜片60，与常规液力支座的结构相同。
然而，根据本发明的液力支座可以进一步包括自动流体打开和关闭单元100，该自动流体打开和关闭单元100安装在上流体腔40和下流体腔50之间以通过电流变化连续地打开和关闭流动路径101，因此保持了常规MRF支座的诸如连续安装特性变化和动态特性上升的变化性的优点，并具有与常规MRF支座相同的特性。
如图2所示，自动流体打开和关闭单元100可以包括轭部110和柱塞120。如图3A和图3B所示，轭部110可以包括：圆柱形主体111，由金属形成并具有敞开的上表面和形成在圆柱形主体111中的容纳空间111a(例如，空腔)；以及线圈固定板112，设置在容纳空间111a的下部区域中并具有缠绕在线圈固定板112上的线圈112a。
主体111和线圈固定板112可以使用多个连接肋113一体地形成，并且流体通道102可以形成在连接肋113之间。线圈固定板112可以形成为大致T形形状，并且线圈112a可以缠绕在竖直形成在线圈固定板112的中心处的圆柱上。如图1或图5A和图5B示例性所示，柱塞120可以包括盘形上部板121，该盘形上部板121安装在轭部110的容纳空间111a内，即与线圈固定板112间隔开指定的间隔，并且可包括多个流体孔径121a、通过硬化(vulcanize)形成在柱塞120的下部的圆柱形橡胶桥接部122以及止动部123(参见图4A和4B)。
当上部板121竖直地移动时，流体孔径121a允许上流体腔40和下流体腔50内的流体流动以防止经受二次负载。例如，当上部板121被磁场拉动时橡胶桥接部122通过橡胶弹性恢复到原始位置时，可以形成流体孔径121a，以允许位于上部板121和线圈固定板112之间的空间中的流体无阻力地自由流动。流体孔径121a可以像常规孔一样操作并影响高频特性。
也可以由橡胶形成并且呈圆锥形形状的止动部123可以被安装成当柱塞120通过轭部110的磁力在容纳空间111a内竖直地移动时防止柱塞120与轭部110之间的连接。此外，安装在轭部110的容纳空间111a内的柱塞120的直径可以小于容纳空间111a的直径，因此，流动路径101可以形成在容纳空间111a和柱塞120之间并且用作与上流体腔40和下流体腔50连通的流体通道。
当柱塞120移动到上流体腔40和下流体腔50时，流动路径101可以用作孔，以改变支座的总体特性。柱塞120可以通过组装线圈固定板112和轭部110的主体111并通过硬化在柱塞120的上部板121的下部形成圆柱形橡胶桥接部122和止动部123来形成，线圈112a缠绕在线圈固定板112上。在上述柱塞120与轭部110联接之后，设置有柱塞120的轭部110可以安装在橡胶构件30内即在上流体腔40和下流体腔50内，可以卷曲轭部110，并且轭部110可以通过压制装配到支架外壳20中，从而完成液力支座的制造。
因此，在根据本发明的用于改善行驶性能的具有连续可变特性的上述液力支座中，当电流被施加到安装在轭部110中的线圈121a时，线圈固定板112通过这种电流产生磁力。
然后，如图6B中示例性所示，上部板121可以通过磁力下降到线圈固定板112。特别地，通过硬化而形成在上部板121处的橡胶桥接部122在与线圈固定板112接触的状态下可以通过上部板121的下降力向外弯曲，从而关闭流动路径101。通过以这种方式连续地打开和关闭流动路径101，根据本发明的液力支座能够保持常规MRF支座的优点，例如连续安装特性变化和动态特性上升的变化性，并且具有与常规MRF支座相同的特性。
此外，流动路径101的宽度可以根据电流的强度而变化。这将参照图6A和图6B进行描述。如图6A中示例性所示，在车辆发动机空转期间电流为0.0A时，与上流体腔40和下流体腔50连通的流动路径101保持约3mm的宽度，并且流体自由地流动到上流体腔40和下流体腔50。
换句话说，流体通过流动路径101流经上流体腔40和下流体腔50，并且一部分流体被限制在下流体腔50内，由此降低了动态特性。因此，可以增加绝缘因子，并且可以降低空转振动。此外，如图6B中示例性所示，当在车辆行驶期间流过约1A的电流时，橡胶桥接部122可以通过减小的力向外弯曲并关闭流动路径101，从而阻止流体的流动。
当流体流动被阻止时，流体可被限制在上流体腔40内，从而提高动态特性。此外，根据本发明的液力支座不使用常规MRF支座中使用的MR流体，而使用普通流体，因此显著降低了生产成本。例如，MR流体的价格为每千克1,200,000韩元，但根据本发明的流体安装中使用的流体的价格为每千克大约10,000韩元，因此生产成本可以大大降低。
从以上描述中显而易见的是，根据本发明的用于改善行驶性能的具有连续可变特性的液力支座可以具有如下效果。
首先，根据本发明的液力支座除了包括普通液力支座的结构之外还包括自动流体打开和关闭单元，并且因此可以以与常规MRF支座相同的方式连续地改变特性。
其次，在常规MRF安装中使用的MR流体中，随着时间的流逝，MR流体中的铁屑下沉，因而导致常规MRF支座发生故障。然而，根据本发明的液力支座使用普通流体(例如，与防冻溶液相同的支座溶液)并且正常地被操作以使得特性的变化随时间正常地进行，因此确保了性能的稳健性。
第三，常规MRF支座中使用的MR流体与橡胶反应，因此耐久性恶化。然而，根据本发明的液力支座使用普通流体(支座溶液)，因此具有与普通液力支座相同的耐用性，从而确保较强的耐用性。
尽管为了说明的目的已经公开了本发明的示例性实施例，但是本领域技术人员将理解的是，在不脱离所附权利要求所公开的本发明的范围和精神的情况下，可以进行各种修改、添加和替换。
