Description
技术领域
本发明属于汽车技术领域,特别涉及一种汽车用空气弹簧上支座、汽车空气弹簧组件和车辆。
背景技术
随着汽车在生活中的普及,人们对汽车的行驶舒适性要求越来越高。汽车在道路上行驶时,在经过不平路面时会产生颠簸,路面对车轮的冲击会传递给车身。弹簧能够对冲击进行缓冲,将动能转化为弹性势能,延缓车身所受载荷,以减轻车身的上下颠簸程度。
空气弹簧的缓冲作用较普通的螺旋弹簧更为明显。另外空气弹簧还具有调节车身高度的功能,此功能是螺旋弹簧所不具备的。基于上述两点原因,空气弹簧的应用越来越多,尤其在对舒适性要求较高的豪华车上,空气弹簧几乎成了标配。空气弹簧上支座作为载荷传递的关键部件之一,要求其具有足够的刚度和强度,以确保车身的可靠性和耐久性,同时还需要有合适的衬套刚度,以获得较好的舒适性。
目前,大多空气弹簧上支座衬套采用过盈压入,衬套外管与上支座壳体之间采用过盈配合。但这种配合形式必然导致衬套外管或者上支座壳体变形。如果衬套外管装有O形密封圈,则在过盈压入时很大可能破坏密封圈。过盈压入的另外一个弊端是不可拆卸。当衬套压出时将需要很大的压出力,这必然导致衬套或者壳体破坏。这种不可拆卸的弊端对零件售后市场造成了极大的困扰。当衬套失效时,由于衬套不可更换,需要更换整个空气弹簧,有时是更换整个空气弹簧带减振器总成。这样售后换件成本将大大增加,消费者抱怨很大。
CN 111873737A涉及汽车底盘空气悬架技术领域,公开一种空气弹簧上支架及汽车底盘空气悬架。其中空气弹簧上支架包括底板、支撑板和加强板,其中底板与空气弹簧连接;支撑板设置于底板的上方,包括主板和设置于主板两侧的两个翼板,主板与车架连接,翼板和主板呈夹角设置;加强板设置于底板和空气弹簧之间,加强板包括平板与设置于平板两侧的两个竖板,平板与内凹结构的底壁抵接,竖板与底板连接。

附图说明
参考附图,本发明的上述以及其它的特征将变得显而易见,其中,
图1示出了根据本发明的一种空气弹簧上支座的剖视图;以及
图2示出了根据本发明的一种空气弹簧上支座的轴侧视图。
具体实施方式
容易理解,根据本发明的技术方案,在不变更本发明实质精神下,本领域的一般技术人员可以提出可相互替换的多种结构方式以及实现方式。因此,以下具体实施方式以及附图仅是对本发明的技术方案的示例性说明,而不应当视为本发明的全部或者视为对本发明技术方案的限定或限制。
在本说明书中提到或者可能提到的上、下、左、右、前、后、正面、背面、顶部、底部等方位用语是相对于各附图中所示的构造进行定义的,它们是相对的概念,因此有可能会根据其所处不同位置、不同使用状态而进行相应地变化。所以,也不应当将这些或者其他的方位用语解释为限制性用语。此外,术语“第一”、“第二”、“第三”等或类似表述仅用于描述与区分目的,而不能理解为指示或暗示相应的构件的相对重要性。
参考图1和图2,它们分别示出了根据本发明的一种空气弹簧上支座100的剖视图以及根据本发明的一种空气弹簧上支座100的轴侧视图。
所述空气弹簧上支座100用于车辆的空气弹簧,其中,所述空气弹簧上支座100构造成具有上壳体1和下壳体2的分体式结构,所述上壳体1和所述下壳体2彼此连接并且形成容纳空间3,所述空气弹簧上支座100还具有衬套4,所述衬套4布置在所述容纳空间3内。
通过将上支座壳体分为两部分,解决了传统上支座不易拆卸衬套导致售后换件成本高的问题;通过采用衬套,能够对所述空气弹簧上支座配合的零件起到减振缓冲作用、例如磨损保护及减少异响等的作用。具体而言,通过技术方案,如果要更换衬套,只需要将上壳体拆卸下来即可,而无需拆卸整个上支座。
所述上壳体1和所述下壳体2可以通过多种方式彼此连接,特别是上下连接。应当理解,上下连接是相对而言的(包括上支座、上壳体、下壳体的命名方式),并且也不是绝对代表上壳体的所有部分均要位于下壳体上方,而是上壳体大致上、总体上处于下壳体之上即可。关于上下壳体的连接方式,示例性的是,所述上壳体1和所述下壳体2通过螺纹紧固件6彼此固定,所述螺纹紧固件6布置在上下壳体的外侧部分处并且从上至下引入到上下壳体内。螺纹紧固件是一种有内螺纹或是外螺纹的机械零件,一般会作为紧固件使用,方便多个组件的组合。最常见的螺纹紧固件是螺钉、螺母及螺栓。不过也有其它的螺纹紧固件,例如笼罩螺帽、螺纹插件、螺纹杆等。而螺纹紧固连接是一种广泛使用的可拆卸的固定连接,具有结构简单、连接可靠、装拆方便等优点。
所述上壳体1在如图所示的实施例中呈现为外周矮平、中间高平的盖子形状,而所述下壳体2呈现为具有内肋的管形,所述内肋用于支撑所述衬套4,而所述下壳体2的下部分用于连接车辆空气弹簧气囊。为了与车身进行连接,可以例如将螺柱7布置在上壳体1的外周处,通过所述螺柱7将空气弹簧组件(含整个空气弹簧上支座100)与车身进行连接。当然,类似地也可以使用其它螺纹紧固件或连接器件来代替螺柱7。
所述衬套4由外向内具有衬套外管41、衬套橡胶42以及衬套内管43。所述衬套内管43例如还能够具有突出部,以便与所述衬套橡胶42的相对应的凹入部进行形状配合地连接。所述衬套4与所述上壳体1、所述下壳体2之间的配合方式如下所示:
所述衬套外管41与所述上壳体1在径向为过盈配合,由此使得整个衬套4不会在所述容纳空间3内发生窜动;
所述衬套外管41与所述下壳体2在径向为间隙或过渡配合,分别对所述上壳体1连同所述衬套4进行拆卸,而无需拆卸需要与空气弹簧气囊相连接的较大、较难以拆卸的下壳体2;
所述衬套橡胶42与所述上壳体1在轴向为过盈配合,所述上壳体1在轴向压紧所述衬套橡胶42,可以有效减少减振器运动过程中导致所述衬套内管43的振动所产生的异响;
所述衬套橡胶42与所述下壳体2在轴向为过盈配合,所述下壳体2在轴向压紧所述衬套橡胶42,可以有效减少减振器运动过程中导致所述衬套内管43的振动所产生的异响;
所述衬套外管41与所述上壳体1在轴向为间隙配合,防止过约束;
所述衬套外管41与所述下壳体2在轴向为间隙配合,防止过约束。
应当理解,过盈配合即利用材料的弹性、变形来实现零件之间的紧密配合,间隙配合是零件之间存在有间隙的配合,而过渡配合是指零件之间装配时可能有间隙配合也可能有过盈配合。上述配合方式可以根据实际情况进行单独使用或混合使用,只要彼此没有冲突的话。
所述衬套内管43具有通孔431,所述通孔431用于安装和固定所述车辆的减振器活塞杆。在所述空气弹簧上支座100用于车辆空气弹簧时,车辆减振器的活塞杆会从下至上穿过所述通孔431。此外,在所述衬套内管43之上可以布置有螺母,所述螺母与所述衬套内管43类似地用于固定所述减振器的活塞杆。所述衬套内管43的上表面和下表面还可以构造成平面,以便于安装和固定所述减振器。
关于所述空气弹簧上支座100各零件的材料和制造方式,示例性的是:
所述上壳体1采用铸铝、锻铝、铸铁或锻钢材料制成;
所述下壳体2采用铸铝、锻铝、铸铁或锻钢材料制成;
所述衬套外管41采用钢材冲压或者钢管机加工制成;
所述衬套内管43采用钢材或铝材或合金材料经冲压或冷镦制成。
其中,铸铝即铸造铝合金,铸铁为铸造铁合金(通常由铁、碳和硅组成的合金),以此类推。另外,冲压件具有薄、匀、轻、强、工件精度高的特点,特别是可制造出带有加强筋、肋、起伏或翻边的工件,以提高其刚性。而冷镦件具有优良的机械性能、精度高、表面光洁度高。
可选的是,在所述衬套外管41上还能够布置有O形密封圈5,并且所述O形密封圈5抵靠所述下壳体2的内侧。通过所述O形密封圈5来实现在所述衬套外管41与所述下壳体2之间密封空气弹簧内部的气体,由此更加支持了所述衬套外管41与所述下壳体2在轴向为间隙配合、所述衬套外管41与所述下壳体2在径向为间隙或过渡配合的设置方式。此外,通过所述衬套4相对于所述上壳体1的配合方式,还又避免了所述O形密封圈5在拆卸时的破坏问题。
就此而言,所述衬套内管43的所述通孔431应机加工,以获得不伤害减振器活塞杆上的O形密封圈的加工精度。
本发明还涉及一种车辆空气弹簧组件,其中,所述车辆空气弹簧组件具有彼此连接的车辆空气弹簧以及上述任一种空气弹簧上支座100。所述车辆空气弹簧布置于所述下壳体2的下方,所述上壳体1连接至所述车辆的车身,所述车辆的减振器位于所述下壳体2下方,并且其活塞杆从下向上穿过所述衬套4和由此穿过整个空气弹簧上支座100向上突出。
所述车辆空气弹簧的皮囊可以箍设于所述下壳体2的下部,也就是说,所述皮囊通过卡箍件、例如扣压环来卡箍至所述下壳体2的下部,例如所述下壳体2的向下延伸的外周部分处,以完成装配。
应当理解的是,本发明的车辆空气弹簧组件可装设在各种车辆上,包括汽油车、柴油车、轿车、货车、客车、混合动力车辆、纯电动汽车等等。因此,本发明的主题还旨在保护装设有本发明的车辆空气弹簧组件的各种车辆。
应当理解的是,所有以上的优选实施例都是示例性而非限制性的,本领域技术人员在本发明的构思下对以上描述的具体实施例做出的各种改型或变形都应在本发明的法律保护范围内。例如,尽管说明书中是结合汽车悬架空气弹簧来描述的,但是,本发明显然可以用于其它各种部位的空气弹簧,只要该空气弹簧上支座衬套需要拆卸维修即可。
