顶部22包括板36,该板36可以具有环形形状,设置在中心轴线A上,用于将空气悬架组件20固定至车辆。具有筒形形状的侧壁38从板36垂直向外地、平行于中心轴线A、并朝向腔室32径向向内地延伸。底壁40从侧壁38朝向中心轴线A径向向内地延伸。侧壁38包括多个第一脊部42,所述多个第一脊部42彼此间隔开,从侧壁38向外并且以与中心轴线A垂直的关系围绕侧壁38环形地延伸,以容纳波纹管26的第一端28。具有环形形状的第一环44在波纹管26的第一端28处设置在波纹管26上,并且围绕顶部22的侧壁38环形地延伸,以将波纹管26固定至顶部22的侧壁38。换句话说,第一环44将波纹管26的第一端28夹在第一环44与侧壁38的第一脊部42之间。
底壁40限定了洞46,该洞46具有圆形形状并且设置在中心轴线A上。具有柱形形状的活塞杆引导件48围绕中心轴线A环形地延伸并且穿过洞46。活塞杆引导件48可以形成第一中心通道(未示出),该第一中心通道沿着中心轴线A延伸,用于容纳活塞杆50。套筒52固定至侧壁38,并且沿着中心轴线A环形地延伸进入腔室32中。具有大致截头锥形状、由弹性体材料(例如,通用热塑性弹性体)制成的内部弹簧54沿着中心轴线A延伸,并且连接至顶部22的套筒52并从顶部22的套筒52延伸进入腔室32中。根据本发明的实施方式,内部弹簧54可以由耐热和/或耐化学性的材料制成(诸如,杜邦公司以商标Hytrel出售的热塑性弹性体)。在一些实施方式中,相比于典型的复杂且昂贵的橡胶形成技术,波纹管26的材料(例如,杜邦公司的Hytrel)和尺寸可以允许通过吹塑法形成波纹管。内部弹簧54限定了第二中心通道56,该第二中心通道56具有大致柱形形状,与第一中心通道成直线(in-line with)设置并且沿着中心轴线A、沿着内部弹簧54的长度延伸,用于允许活塞杆50延伸进入腔室32中。在一些实施方式中,内部弹簧54是震动缓冲器(jounce bumper),并且可以由可压缩材料制成,以在空气悬架组件20被压缩时吸收阻尼器34的能量。
阻尼器34包括壳体58和帽60,壳体58和帽60各自具有筒形形状并且沿着中心轴线A延伸。壳体58在近端(未示出)与远端62之间延伸。远端62位于腔室32中。近端位于腔室32的外部,用于将空气悬架组件20连接至车辆。帽60在远端62处固定至壳体58,以在壳体58内部形成隔室64。帽60和壳体58限定了第三中心通道66,该第三中心通道66沿着中心轴线A延伸,用于容纳活塞杆50。应理解,在一些实施方式中,阻尼器34可以是液压阻尼器,液压流体设置在隔室64内部,并且活塞杆50可以包括液压活塞67,该液压活塞67设置在隔室64内部,用于与液压流体相互作用。活塞杆50和液压活塞67可在压缩冲程与回弹冲程之间移动。在压缩冲程期间,活塞杆50和液压活塞67远离帽60轴向移动。在回弹冲程期间,活塞杆50和液压活塞67朝向帽60轴向移动。
壳体58还限定了两组孔68、70,所述两组孔68、70包括彼此轴向间隔开的第一组孔68和第二组孔70。第一组孔68位于壳体58的远端62附近并且围绕中心轴线A设置。第一组孔68的各个孔68与第一组孔68的相邻孔周向间隔开,用于与帽60相互作用。帽60包括径向向内延伸的多个突起72,其中,多个突起72中的一突起72容纳在第一组孔68的一孔中,以将帽60固定至壳体58。第二组孔70位于腔室32的外部,与底部24相邻。第二组孔70围绕中心轴线A彼此周向间隔开,用于与底部24相互作用。
底部24包括主体74,该主体74围绕中心轴线A在阻尼器34与波纹管26之间环形地延伸。主体74具有围绕主体74延伸的周缘76。主体74包括多个第二脊部78,所述多个第二脊部78彼此轴向间隔开,从主体74垂直于中心轴线A向外延伸,用于容纳波纹管26的第二端30。具有环形形状的第二环80在波纹管26的第二端30处设置在波纹管26上,并且围绕底部24的主体74环形地延伸,以将波纹管26固定至底部24的主体74。换句话说,波纹管26的第二端30夹在第二环80与第二脊部78之间,以将波纹管26的第二端30固定至底部24。底部24限定了第四中心通道82,该第四中心通道82具有柱形形状,设置在中心轴线A上,用于容纳阻尼器34。底部24还包括套环部84,该套环部84具有筒形形状,沿着中心轴线A延伸,用于将底部24固定至阻尼器34。根据本发明的实施方式,套环部84可以包括至少一个销钉86,该至少一个销钉86朝向中心轴线A径向向内延伸,用于与壳体58的第二组孔70接合,以将阻尼器34固定至底部24。应注意,可以使用其它方式(诸如,夹具、螺钉或其它公知方法)将阻尼器34固定至底部24。
根据本发明的实施方式,波纹管26可以具有形成在设置在腔室32附近的内表面88与设置在腔室32外部的外表面90之间的变化的波纹管厚度T。波纹管26具有一系列回旋部,各个回旋部具有大致正弦形(例如,“W”形)的横截面,在第一端28与第二端30之间延伸,以向波纹管26提供强度并允许波纹管26压缩和缩回。现在参考图4,一系列回旋部92中的一回旋部92在两个外凸部93之间以波浪状形式延伸,各个外凸部93具有大致弧形(arcuate)横截面,内凸部94设置在外凸部93之间。沿着中心轴线A彼此间隔开的外凸部93从内凸部94径向向外设置。各个外凸部93界定了波纹管26的外径DO。具有大致恒定的桥接部厚度TB、在内表面88与外表面90之间延伸的桥接部96在各个外凸部93与内凸部94之间延伸,以将内凸部94连接至外凸部93。具有大致U形横截面的内凸部94从外凸部94径向向内设置并且设置在外凸部94之间。内凸部94在桥接部96之间延伸,并且界定了波纹管26的内径DI
外凸部93具有外外凸部半径R1和内外凸部半径R2,从而限定了在外表面90与内表面88之间延伸的外凸部厚度TO。内凸部94具有外内凸部半径R3和内内凸部半径R4,从而限定了在内表面88与外表面90之间延伸的内凸部厚度TI。如图所示,外凸部厚度TO可以沿着外凸部93的轮廓变化,外凸部厚度TO在外凸部93的外末端(tip)98处最大。内凸部94的厚度也可以沿着内凸部94的轮廓变化,内凸部厚度TI在内凸部94的内末端100处最大。桥接部96具有在内表面88与外表面90之间延伸的桥接部厚度TB。各个回旋部92具有在外凸部93之间延伸的高度H和在外径DO与内径DI之间延伸的宽度W。内凸部94沿着回旋部92的中间平面M设置,该中间平面M可以大约是高度H的一半。应理解,桥接部96可以在外凸部93与内凸部94之间具有轻微曲率半径(即,桥接部外半径和桥接部内半径),或者可以具有大致线性轮廓。根据本发明的实施方式,波纹管26可以包括在波纹管26的第一端28与第二端30之间延伸的约16个回旋部。应理解,在本发明的一些实施方式中,波纹管26可以模制或紧固至设置在回旋部92四周(amid)或多个回旋部92与顶部22或底部24之间的硬化套筒部,以向波纹管26提供附加结构完整性。
在工作时,底部24、阻尼器34和波纹管26可沿着中心轴线A在如图3所例示的未变形位置与如图2所例示的压缩位置(即,完全凸起位置)之间移动。在压缩位置,内部弹簧54被压缩在底壁40与阻尼器34之间。相应地,在压缩位置,波纹管26也被压缩,其中,相邻内凸部94彼此抵接。另外,在压缩位置,相邻外凸部93彼此抵接。在未变形位置,内部弹簧54和波纹管26未变形。应注意,在工作期间,空气悬架组件20还可以保持在默认工作位置,空气悬架组件20被部分压缩,如图1所例示。当空气悬架组件20例如由于车辆通过凸起而压缩时,底部24、阻尼器34和波纹管26朝向顶部22轴向移动,从而压缩空气悬架组件20。在更强烈的压缩期间,阻尼器34的帽60接合并压缩内部弹簧54,以软化阻尼器34与顶部22之间的接触。
在如图4所例示,相比于传统的空气弹簧,处于未变形位置的回旋部92的尺寸可以允许载荷以可预测的方式偏转。换句话说,与传统的空气弹簧的载荷补偿类似,回旋部92的形状可以提供车辆的载荷补偿和升高/降低功能。例如,在未变形位置,波纹管26的如在外凸部93的外表面90处限定的外径DO可以为约71.44毫米,而波纹管的如在内凸部94的内表面88处限定的内径DI可以为约45.1毫米。回旋部92的高度H可以为约24.68毫米,从外凸部93到中间平面M的距离可以为约12.34毫米,并且宽度W可以为约26.31毫米。此外,外外凸部半径R1可以为5.21毫米,并且内外凸部半径R2可以为约2.74毫米。
在未变形位置,内内凸部半径R3可以为约4.22毫米,并且在中间平面M的一侧上延伸约30度,在中间平面M的另一侧上延伸约30度。换句话说,内内凸部半径R3可以在中间平面M的任一侧上延伸2.13mm。外凸部厚度TO可以跨外凸部93的轮廓变化,但是可以为至少约6.13毫米。内凸部厚度TI也可以跨内凸部94的轮廓变化,但是可以为至少约6.25毫米。桥接部96的外表面88可以相对于外凸部93以约11度的角度延伸,并且桥接部96的内表面90可以相对于外凸部94以约8度的角度延伸。换句话说,桥接部厚度TB可以跨桥接部96的轮廓变化。例如,在外凸部93与内凸部94之间,桥接部厚度TB可以增大。
根据本发明的实施方式,阀(未示出)可以被设置成与腔室流体连通,用于响应于施加至空气悬架组件20的力而改变腔室32中的压力(即,控制腔室32中容纳的增压空气)。通过基于施加至空气悬架组件20的力来控制施加到腔室32的增压空气的压力,可以使波纹管26***并且可以调节空气弹簧的推力。在一些实施方式中,腔室中的增压空气对应于底部24相对于顶部22的位置。例如,阀可以被构造成选择性地向腔室32施加介于0巴到至少约5巴之间的气压,以控制空气悬架组件20的整个范围。波纹管26的强度由于回旋部92的设计而可以使空气悬架组件20能够发挥作用并利用较低功率压缩机控制。例如,回旋部92的厚度、高度、宽度、曲率和数量可以为空气悬架组件20提供弹性。
参考图5,应理解,在一些实施方式中,在对阀进行选择性控制的情况下,空气悬架组件20的载荷偏转曲线通常可以与传统的空气弹簧的载荷偏转曲线相关。例如,如图5所示,当波纹管26在强压(scragg)下从接收约1530牛顿而返回时,随着波纹管上的力的速率下降至约每毫米18牛顿,阀被打开。为了获得传统的弹簧响应,随着第二压缩施加至空气悬架组件20,阀被关闭并且在第二压缩期间可以在腔室32中保持约3巴的压力。在一些实施方式中,在默认工作位置,当阀被打开时,空气悬架组件20暴露于约1090牛顿,并且在强压下暴露于约1530牛顿。当空气悬架组件20支撑约4320牛顿的载荷时,可以关闭阀,以在默认位置将腔室32的气压保持为约3巴。在完全压缩(即,完全凸起)期间,空气悬架组件20可以经历每毫米20千牛顿至25千牛顿。
显然,根据以上教导,本发明的许多修改和变型(例如,与先前描述为围绕阻尼器构建的组件相比,作为独立的空气弹簧组件)是可能的,并且可以以不同于具体描述的方式但在所附权利要求的范围内的方式来实践。
