Description

沙漏式空气弹簧系统
技术领域
本发明主要涉及缓冲减震技术,尤其涉及一种沙漏式空气弹簧系统。
背景技术
空气弹簧组件应用广泛,如铁路车厢、重载车辆以及其它缓冲或减震较为重要的应用场合。通常,这种弹簧组件包括位于一对刚性端板之间的弹性体。弹性体由橡胶制成,并被作用于弹簧组件的载荷压缩。现有技术中,沙漏式辅助弹簧在低载荷时,具有较低的垂向刚度,故其舒适性非常好,但是在高载荷下,沙漏式辅助弹簧的非线性导致高载荷下垂向刚度很大,严重影响了其舒适性,而在某些重载列车的项目上,特别是双层动车组列车,要求高载荷下辅助弹簧垂向刚度特别小,因此现有的沙漏式辅助弹簧无法满足此种要求。
发明内容
本发明要解决的技术问题是克服现有技术的不足,提供一种结构简单、安装方便、重载垂向刚度底、舒适性和稳定性高的沙漏式空气弹簧系统。
为解决上述技术问题,本发明采用以下技术方案:
一种沙漏式空气弹簧系统,包括上盖板、气囊、上端板和下端板,所述上盖板的外周通过所述气囊与上端板的外周连接,所述上端板和下端板之间连接有分体式的低位沙漏弹性体和高位沙漏弹性体,所述低位沙漏弹性体和高位沙漏弹性体之间连接有刚性隔板。
作为上述技术方案的进一步改进:
所述上盖板底面的中心位置设有限位台,所述上端板顶面的中心位置设有限位槽,泄气状态时所述限位台位于限位槽内。
所述限位台和限位槽均包括一对斜面和一对直面,其直面沿车体的长度方向布置,其斜面相应沿车体的宽度方向布置。
所述低位沙漏弹性体和高位沙漏弹性体的中心相互贯穿,所述下端板顶部中心设有伸至低位沙漏弹性体和高位沙漏弹性体的贯穿孔内的止挡部。
所述刚性隔板外周面位于低位沙漏弹性体和高位沙漏弹性体外部。
所述上盖板的外周面底部设有扣环,所述气囊一端与扣环扣接,另一端与上端板自密封连接。
与现有技术相比,本发明的优点在于:
本发明的沙漏式空气弹簧系统,包括上盖板、气囊、上端板和下端板,上盖板的外周通过气囊与上端板的外周连接,上端板和下端板之间连接有分体式的低位沙漏弹性体和高位沙漏弹性体,低位沙漏弹性体和高位沙漏弹性体之间连接有刚性隔板。该结构中,通过分体式结构的低位沙漏弹性体和高位沙漏弹性体形成串联结构,增加了上端板和下端板之间弹性体的高程,即大大降低了辅助弹簧的在重载下的垂向刚度,提高了辅助弹簧的在重载下的舒适性;另外,在高程增加的同时,也增加了上端板和下端板之间弹性体的横向位移,该结构通过刚性隔板将低位沙漏弹性体和高位沙漏弹性体完全隔开,即能够避免辅助弹簧的横向失稳,提高了辅助弹簧横向位移的稳定性;该结构中,刚性隔板安装时不会破坏低位沙漏弹性体和高位沙漏弹性体,其结构简单,提高了安装的方便以及保证了低位沙漏弹性体和高位沙漏弹性体的完整性。

具体实施方式
以下将结合说明书附图和具体实施例对本发明做进一步详细说明。
如图1和图2所示,本发明沙漏式空气弹簧系统的一种实施例,包括上盖板1、气囊2、上端板3和下端板4,上盖板1的外周通过气囊2与上端板3的外周连接,上端板3和下端板4之间连接有分体式的低位沙漏弹性体5和高位沙漏弹性体6,低位沙漏弹性体5和高位沙漏弹性体6之间连接有刚性隔板7。该结构中,通过分体式结构的低位沙漏弹性体5和高位沙漏弹性体6形成串联结构,增加了上端板3和下端板4之间弹性体的高程,即大大降低了辅助弹簧的在重载下的垂向刚度,提高了辅助弹簧的在重载下的舒适性;另外,在高程增加的同时,也增加了上端板3和下端板4之间弹性体的横向位移,该结构通过刚性隔板7将低位沙漏弹性体5和高位沙漏弹性体6完全隔开,即能够避免辅助弹簧的横向失稳,提高了辅助弹簧横向位移的稳定性;该结构中,刚性隔板7安装时不会破坏低位沙漏弹性体5和高位沙漏弹性体6,其结构简单,提高了安装的方便以及保证了低位沙漏弹性体5和高位沙漏弹性体6的完整性。
本实施例中,上盖板1底面的中心位置设有限位台11,上端板3顶面的中心位置设有限位槽31,泄气状态时限位台11位于限位槽31内。泄气状态时,限位台11位于限位槽31内,对上盖板1横向方向的位移进行了约束限位,解决泄气状态下中,空气弹簧系统在车体长度和宽度方向不同限位间距的要求。
本实施例中,限位台11和限位槽31均包括一对斜面和一对直面,其直面沿车体的长度方向布置,其斜面相应沿车体的宽度方向布置。这样设置,使得在车体长度方向的限位间距大于车体宽度方向的限位间距,以适应于车体运动惯性,又能防止车体左右移动过大。
本实施例中,低位沙漏弹性体5和高位沙漏弹性体6的中心相互贯穿,下端板4顶部中心设有伸至低位沙漏弹性体5和高位沙漏弹性体6的贯穿孔内的止挡部41。该止档部41保证了车辆的总体下沉量,确保在高载荷和动载等情况下,车体与转向架不发生干涉。
本实施例中,刚性隔板7外周面位于低位沙漏弹性体5和高位沙漏弹性体6外部。这样设置,使得刚性隔板7整体延伸至低位沙漏弹性体5和高位沙漏弹性体6外部,便于安装。
本实施例中,上盖板1的外周面底部设有扣环12,气囊2一端与扣环12扣接,另一端与上端板3自密封连接。该结构中,气囊2小子口与下端板3采用自密封连接,防止漏气。
虽然本发明已以较佳实施例揭示如上,然而并非用以限定本发明。任何熟悉本领域的技术人员,在不脱离本发明技术方案范围的情况下,都可利用上述揭示的技术内容对本发明技术方案做出许多可能的变动和修饰,或修改为等同变化的等效实施例。因此,凡是未脱离本发明技术方案的内容,依据本发明技术实质对以上实施例所做的任何简单修改、等同变化及修饰,均应落在本发明技术方案保护的范围内。
