Description
技术领域
本发明涉及一种提高空气弹簧横向稳定性的组合式橡胶关节,属于运输装置减隔振技术领域。
背景技术
空气弹簧是一种具有支撑、缓冲、高度调节和角度调节等功能的装置,被广泛应用于商业汽车、巴士、轨道车辆、航运、航空等交通运输装置的隔振***中,能够实现缓冲、减振和隔振的作用。在运输装置运行过程中,空气弹簧能对车体提供横向和纵向的刚度和承载,垂向刚度是通过调节橡胶气囊的内压力实现的,横向刚度是通过橡胶气囊在横向变形后的反作用力实现的。由于橡胶气囊横向变形所提供的反作用力较小,空气弹簧的横向刚度小,在运输装置转弯行驶或横向受力大的情况下,空气弹簧的止挡产生横向限位作用时,会对运输装置产生冲击现象,从而影响运输装置运行的平稳性或造成部件损坏。
当空气弹簧用于舰艇浮阀的隔振***中时,空气弹簧能有效降低传递到基座和船体的冲击载荷,从而有效降低船体振动产生的自噪声和辐射噪声,同时能够很好的隔离船体底部的冲击加速度,避免受冲击时舰载设备损坏。但是,常用的空气弹簧横向刚度较低,横向变形能力大,加之舰艇舱室空间狭小,当舰艇在航行过程中承受摇摆及侧倾工况时,舰艇浮筏及各设备的横向位移较大,将导致浮筏与其他设备或舱壁相互干涉,影响舰艇安全。
综上所述,如何在保持原有空气弹簧减振性能的基础上,进一步提高空气弹簧的横向稳定性,以适用舰艇浮筏隔振***的特殊要求,是亟需解决的技术问题。
发明内容

为达到上述目的,本发明采用的技术方案是:一种提高空气弹簧横向稳定性的组合式橡胶关节,组合式橡胶关节包括串联设置的用以增加空气弹簧横向反力的定位轴套和为空气弹簧提供垂向弹性应急支撑的缓冲橡胶垫,缓冲橡胶垫位于定位轴套的下端。

优选的,内套靠近缓冲橡胶垫的下端部一凸出于外套靠近缓冲橡胶垫的下端部二而使得下端部一与下端部二之间形成高度差A,定位轴套通过外套的下端部二与缓冲橡胶垫串联连接。
优选的,缓冲橡胶垫包括上板、下板和硫化在上板和下板之间的橡胶体二,上板的外侧部向上凸出形成连接台,定位轴套和缓冲橡胶垫通过外套的下端部二与连接台串联连接。

具体实施方式
下面结合附图1-6对本发明的实施例做详细说明:
一种提高空气弹簧横向稳定性的组合式橡胶关节,其中空气弹簧包括:上支座1、气囊2和下支座3,上支座1和下支座3之间形成型腔一和型腔二;上支座1包括上顶板101和位于上顶板101下端的外侧板102;下支座3包括下底板301,下支座3中下底板301的中部向上延伸形成型腔二,上支座1的上顶板101中部下端设有伸入型腔二内的中心销103;外侧板102和型腔二的腔壁302之间形成型腔一,气囊2设于型腔一内。
如图1所示,组合式橡胶关节包括串联设置的用以增加空气弹簧横向反力的定位轴套4和为空气弹簧提供垂向弹性应急支撑的缓冲橡胶垫5;定位轴套4和缓冲橡胶垫5均设于型腔二内,缓冲橡胶垫5位于定位轴套4的下端。定位轴套4包括外套402、内套401和硫化在内套401和外套402之间的橡胶体一403,定位轴套4的内套内周面401a上设有外螺纹,中心销103的销壁上设有内螺纹,定位轴套4通过内套401螺纹连接在中心销103上;定位轴套4的外套外周面402b上涂有润滑酯,润滑脂对外套外周面402b具有润滑和密封作用,定位轴套4通过外套外周面402b与型腔二的腔壁302滑动连接。在工作过程中,定位轴套4可随着上支座1一起运动,通过定位轴套4的橡胶体一403可增强空气弹簧的横向反作用力,提高空气弹簧的横向稳定性。
如图1所示,定位轴套4如M方向所示的横向刚度和N方向所示的垂向刚度比≥10,通过提高定位轴套4的横垂刚度比,可在大幅度提高空气弹簧横向刚度及横向承载能力的同时,降低对空气弹簧垂向刚度的附加影响,保证空气弹簧的垂向减隔振效果。
橡胶体一403的厚度H大于空气弹簧的横向位移S,具体为:H≥2S。受空气弹簧***安装尺寸的限制,定位轴套4的整体尺寸较小,但空气弹簧***的横向位移S通常较大,通过增加橡胶体一403的胶层厚度,可确保空气弹簧***的自由度。同时,当橡胶体一403的厚度H的值越大时,定位轴套4的横向刚度越小,将降低空气弹簧的横向稳定性,因此将定位轴套4的橡胶预压缩量L设置为:橡胶体一403的预压缩量L≥0.1H,可在保证空气弹簧***自由度的同时,增加空气弹簧横向刚度,提高空气弹簧的横向稳定性。
为了进一步降低定位轴套4的垂向刚度,增加定位轴套4的横垂比,增加空气弹簧的横向稳定性,将橡胶体一403设为圆柱体结构或反球形结构。圆柱体结构的橡胶体一403如图5所示,反球形结构的橡胶体一403如图2所示,本实施例里优选为将橡胶体一403设为如图2所示的反球形结构,即橡胶体一403的两端部的橡胶型面朝向橡胶体一403的中部内凹,使得橡胶体一403的两端面处形成凹腔16,可降低定位轴套4的垂向刚度,同时,当定位轴套4承载变形时,凹腔16能为橡胶体一403的橡胶变形提供形变容积空间,防止橡胶体一403两端部的橡胶褶皱变形断裂,增强橡胶体一403的疲劳寿命。
为了增大橡胶体一403的自由面,以释放橡胶体一403由于预压缩导致的橡胶应力,进一步提高橡胶体一403的疲劳寿命,外套402靠近橡胶体一403的内侧两端部均设有开口一10,内套401靠近橡胶体一403的外侧两端端部均设有开口二17;开口一10和开口二17均包括弧线段和直线段,开口一10的直线段与外套外周面402b平行设置,开口二17的直线段与内套内周面401a平行。如图2和图3所示,橡胶体一403在两端部开口处延伸至开口一10和开口二17上,开口一10朝向外套402两端部依次设有弧线段一11、直线段一13和弧线段二12,直线段一13设于弧线段一11与弧线段二12之间并与外套外周面402b平行设置;开口二17朝向内套401两端部依次设有弧线段三18和直线段二19,直线段二19与内套内周面401a平行设置。通过弧线段一11、弧线段二12和弧线段三18避免硫化在弧线段一11、弧线段二12和弧线段三18处的橡胶体一403在变形时应力集中,增强橡胶体一403的使用寿命,通过直线段一13和直线段二19增强硫化在直线段一13和直线段二19处的橡胶体一403的横向刚度。外套402上端部上硫化有橡胶包胶一601,通过包胶一601避免上支座1受载下移与外套402上端部接触时硬接触。
如图2所示,内套401靠近缓冲橡胶垫5的下端部一14凸出于外套402靠近缓冲橡胶垫5的下端部二15而使得下端部一14与下端部二15之间形成高度差A,其中5mm≤A≤10mm,优选为A=6mm。如图1和图4所示,缓冲橡胶垫5包括上板501、下板502和硫化在上板501和下板502之间的橡胶体二503,上板501的外侧部向上凸出形成连接台20。定位轴套4通过外套402的下端部二15与缓冲橡胶垫5的连接台20串联连接,连接台20的上端面或外套402的下端部二15上硫化有包胶二602,本实施例优选在连接台20的上端面上硫化包胶二602,通过包胶二602避免连接台20与下端部二15硬接触。通过高度差A可抵消垂向方向上空气弹簧由于运动差异导致的垂向不对称载荷,提高定位轴套4的垂向疲劳寿命,避免垂向小幅振动过程中定位轴套4与缓冲橡胶垫5脱离及碰撞造成噪声,减少***的整体冲击力及噪声。缓冲橡胶垫5包括位于下板502上方的中部空腔505,中心销103可伸入中部空腔505内,定位轴套4的下方、缓冲橡胶垫5的上方、中心销103下方和中部空腔505形成气室一8;缓冲橡胶垫5在中部空腔505内利用紧固螺栓506通过下板502固定连接在型腔二的底壁302b上,缓冲橡胶垫5的连接台20外周面与腔壁302间隙配合,连接台20的外周面与型腔二的内壁之间设有气流间隙一905,连接台20上设有与气流间隙一905相连通的气流孔906;橡胶体二503靠近型腔二内壁的一侧的橡胶型面朝向中部空腔505内凹使得橡胶体二503与型腔二的内壁之间形成气室二9,气室二9与气室一8通过气流间隙一905和气流孔906相连通;为了调整缓冲橡胶垫5的垂向刚度,可在橡胶体二503中增设一个或多个隔片504,本实施例中设置了一个隔片504,隔片504与型腔二的内壁间设有气流间隙二907,以使得气室二9中位于隔片504的上下两方均相互连通;通过气室一8和气室二9之间气体的相互流通,气体在流通过程中可产生阻尼效应而吸收空气弹簧的冲击动能,进一步提高空气弹簧的横向稳定性;当气囊2失效时,空气弹簧的上支座1直接落在定位轴套4的外套402上端,通过外套402直接将垂向载荷传递给定位轴套4,缓冲橡胶垫5可避免该条件下过大的垂向载荷造成定位轴套4轴损坏,同时缓冲橡胶垫5可提供一定的弹性支撑,避免刚性支撑造成设备振动过大而损坏。
气囊2位于型腔一中且与定位轴套4并联连接在型腔二腔壁302的两侧,通过定位轴套4与气囊2为空气弹簧提供横向反作用力,提高空气弹簧的横向稳定性;同时当承受载荷时,气囊2被压缩,当载荷解除时,被压缩的气囊2的回弹力可为空气弹簧提供复位力使得空气弹簧复位,同时,辅助气室一8与气室二9中形成气压差,使得气体在气室一8和气室二9间流动。
以上的仅是本发明的实施例,该发明不限于此实施案例涉及的领域,方案中公知的具体结构及特性等常识在此未作过多描述。应当指出,对于本领域的技术人员来说,在不脱离本发明内容的前提下,还可以作出若干变形和改进,这些也应该视为本发明的保护范围,这些都不会影响本发明实施的效果和专利的实用性。本申请要求的保护范围应当以其权利要求的内容为准,说明书中的具体实施方式等记载可以用于解释权利要求的内容。
