Abstract

一个液力弹簧的液体容积(4a、4b)一方面通过一个硫化到一个外环(8)中的弹簧元件(6)封闭；另一方面通过一个补偿膜片(10)限定容积(4a、4b)。要改善补偿膜片(10)和外环(8)之间的密封特性。为此目的，将补偿膜片(10)固定夹紧在外环(8)与盖(12)之间。优选的是，外环(8)和盖(12)的相对置的密封面(14、16)平面地构成。补偿膜片(10)的外缘(18)可以具有一个加厚部(22)，该加厚部充满一个以相同半径形成于外环(8)中的环形槽(24)。该液力弹簧尤其是用于轨行车中的初级弹簧。

Description

液力弹簧
技术领域
本发明涉及一种液力弹簧，尤其是用于轨行车中的初级弹簧。
背景技术
上述类型的液力弹簧公开在题目为“液力减振弹性支承体”的专利文献DE 44 46 800 C1中。
在该专利文献中借助于图1a所述的支承体包括一个弹簧元件1，该弹簧元件一方面与一个连接件11固定连接，另一方面与一个圆柱壳体3固定连接、特别是硫化在一起。在壳体3上螺纹连接有相对置的连接件12，具有杯状空气补偿孔13.1的支承盖与这个连接件连接成一体。该支承体的液力减振系统由工作腔室6和通过高挠性的弹性补偿膜片2向外封闭的补偿腔室7以及一个形成于隔板5中的连接通道4构成，封闭的液压流体通过该通道可在这两个腔室之间节流地流入和流出。
三个不同的部件，即壳体3、隔板5和支承盖13彼此紧靠在补偿膜片2的外缘上。特别是必须在相对置的表面上彼此极其精确地定位这三个部件，以便一方面确保工作腔室6与补偿腔室7之间、另一方面确保工作腔室6与外腔室之间足够的密封特性。在实际的连续工作中已经表明，改善密封特性是有意义的。
发明内容
本发明的任务在于，进一步改进上述类型的结构，特别是要可靠地避免膜片边缘区域中可能的泄漏。
上述任务的技术方案在于一种液力弹簧，尤其是用于轨行车中的初级弹簧，其液体壳体一方面通过一个橡胶弹性的弹簧元件封闭，另一方面通过一个高挠性的弹性补偿膜片封闭，通过一个具有至少一个连接通道的隔板将壳体分成两个完全用一种液压流体充满并可交替改变容积的腔室，即一个邻接弹簧元件的工作腔室和一个邻接补偿膜片的补偿腔室，其中，所述弹簧元件具有一个硫化的外环，所述补偿膜片借助于一个盖压力密封地固定在该外环上，所述外环和盖各具有一个平面构成的边缘，它们彼此对准并将所述补偿膜片的外缘固定夹紧在它们之间。
另外，按照本发明的结构的优点是在更简便地安装并在允许较大公差的情况下具有更好的密封特性。
以简单的方式将补偿膜片可靠地密封夹紧在外环与盖之间。外环和盖的相对置的表面最好平面地构成。可以在较大公差的情况下对密封面稍加后处理。
按照本发明的液力弹簧的扩展结构规定，外环的密封面具有一个圆形槽，补偿膜片具有一个与该槽配合的边缘加厚部。由此在安装时易于调整，并改善了在夹紧状态中的固定。
还可以设想，这样构成膜片的至少一个边缘加厚部，使该膜片贴靠在夹紧区域的外部和/或内部。这种结构还提高了膜片的稳定就位和固定。
最后，膜片在夹紧区域中设置有一个环形加厚轮廓。由此可在夹紧力不均匀分布时进一步改善密封特性。
附图说明
下面借助于一个实施例详细描述按照本发明的液力弹簧。
图1以纵向截面示出了一个液力弹簧。
图2、3和4分别示出了该液力弹簧的细节部分，其中：
图2以纵向截面示出了外环；
图2a示出了图2的局部X；
图3a以纵向截面示出了盖；
图3b以顶视图示出了盖；
图4以纵向截面示出了膜片；
图4a示出了图4的局部X。
具体实施方式
按图1构成的液力弹簧2的液体容积4a、4b通过一个硫化在外环8中的弹簧元件6向“下”封闭。通过一个膜片10向“上”限定容积4a、4b。
膜片10借助于一个盖12压力密封地固定在外环8上。为此目的，不论是外环8还是盖12都分别具有一个平面的密封面14或16(图2或图3)。膜片10的外缘18在平面的密封面14、16之间延伸(图4)。使盖12和外环8相互连接的螺栓20确保将盖12压力密封地固定在外环8上。
设置在平面的密封面14、16之间的膜片外缘18的固定由此得到改善，即膜片10在其外缘18上具有一个环形的加厚部22(图4、图4a)，该加厚部卡入一个相应形成在外环8的密封面14中的槽24里面(图2)。
为了保证弹簧的减振特性，对上述两个分容积4a和4b(工作腔室4a、补偿腔室4b)之间的隔板26设置补偿通道28。
