背景技术
悬架是车辆的车架与车桥或车轮之间的一切传力连接装置的总称,悬架的主要作用是传递作用在车轮和车身之间的一切力和力矩,典型的车辆悬架结构由弹性元件、减振器及导向机构等组成,这三部分分别起缓冲,减震和力的传递作用。
双横臂独立悬架作为一种典型的独立悬架,除拥有上述优点之外,通过灵活设计支撑臂本体结构,并配合调整上、下横臂长度和布置,可最大限度的降低车辆中部高度,同时增加过道宽度,提升了了车辆乘坐空间和上下车的方便性,使得该类型悬架在大载荷商用车辆上的应用越来越受到重视。
现有使用空气弹簧的双横臂独立悬架中,无论前、后悬架,单侧悬架仅安装单个气囊作为弹性元件,或不满足载荷要求,或因气囊自身体积过大影响整车底盘布置。
因此,如何在不影响整车底盘布置的前提下提高承受载荷能力,是目前本领域技术人员亟待解决的问题。

此外,下面所示的实施例不对权利要求所记载的发明内容起任何限定作用。另外,下面实施例所表示的构成的全部内容不限于作为权利要求所记载的发明的解决方案所必需的。
请参阅图1至图2,本发明实施例中的独立悬架系统,包括:
支撑臂100;用于牵引支撑臂100上部的上横臂200;用于牵引支撑臂100下部的下横臂300;和中部设置在支撑臂100上的气囊减震支架400,气囊减震 支架400位于支撑臂100一侧设置有第一气囊和第一减震器,气囊减震支架400位于支撑臂100另一侧设置有第二气囊500和第二减震器700。
使用本发明中的独立悬架系统时,通过设置气囊减震支架400能够将第一气囊和第二气囊500位于支撑臂100的两侧,从而扩展了第一气囊和第二气囊500与轮胎的安全距离,防止车辆上下过程中干涉第一气囊和第二气囊500,第一气囊和第二气囊500的大小不再受限,且第一气囊和第二气囊两个气囊的设置使得该独立悬架系统能够承受更大的载荷,因此,采用本发明中的独立悬架系统能够突破现有技术中局限性,能够在重型车上应用。
需要说明的是,本发明实施例中通过设置气囊减震支架400扩展了第一气囊和第二气囊500与轮胎的安全距离。因此,第一气囊和第二气囊500的大小不再受限。
上述支撑臂100实现了轮系组件与独立悬架系统的连接,气囊减震支架400通过螺栓安装在支撑臂100上,以减小支撑臂100的加工成本。为了进一步保证该气囊减震支架400的强度,该气囊减震支架400为一体式结构。

第一上安装座205设置有第一上球铰;第二上安装座206设置有第二上球铰;第三上安装座与气囊减震支架400通过第三上球铰连接。通过设置第一上 球铰、第二上球铰和第三上球铰连接,对车辆的振动起着缓冲的作用,整车的作用下使车辆具有更高的舒适性。
下横臂300包括设置在气囊减震支架400下的下安装体,自下安装体向两侧延伸的第一下摆支臂302和第二下摆支臂303,以及连接第一下摆支臂302和第二下摆支臂303的末端的第三下摆支臂304;第一下摆支臂302与第三下摆支臂304的相连接的部位设置有与车架连接的第一拐角设置有第一下安装座305;第二下摆支臂303与第三下摆支臂304的相连接的部位设置有第二拐角设置有第二下安装座306;下安装体与气囊减震支架400连接的部位设置有第三下安装座。即下横臂300为三角形结构。

上横臂200和下横臂300除了为三角形结构外还可以是本领域常见的其他结构形式,为了提高上述上横臂200和下横臂300的强度,本发明实施例中优选的将上横臂200为一体式结构;下横臂300为一体式结构。上横臂200与下横臂300长度不等。这样可以减少车辆运动过程中轮胎轮距的变化,减小轮胎的磨损,延长使用寿命。
在本发明还公开了一种车辆,该车辆包括上述任一项的独立悬架系统。由于上述独立悬架系统具有以上有益效果,包括上述独立悬架系统的车辆也具有相应的效果,此处不再赘述。
对所公开的实施例的上述说明,使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的,本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下,在其它实施例中实现。因此,本发明将不会被限制于本文所示的这些实施例,而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
