Description
车辆轮轴升降装置 技术领域
本发明是涉及一种车辆轮轴升降装置， 特别是一种用以调整大型车辆 的车轮高度的车辆轮轴升降装置。
背景技术 大型车辆例如大货车或拖板车等， 由于需要载运具有相当体积与重量 的货物， 因此其车身会具有相当多组的车轮组平均负重。 然而， 在平时无 载物 （空车） 的时候， 只需要前后两组车轮组 （意即只需前后四个轮胎） 就足以负担空车状态时的负重而行驶在路上， 因此， 一般大型车辆会设有 例如中国台湾 529561 专利号所揭示的车辆轮轴升降装置来使其他车轮组 略微提升， 使其不与地面直接接触， 一方面也可以减少轮胎磨损以及减少 必须克服轮胎与地面摩擦所耗的能源， 一方面可以减少回转半径， 使拖车 头便于回转与方便操作。
许多大型车辆会将部分零件设置于接近轮轴处， 但是， 上述专利为了 设置一升降用的气囊以及一避震用的气囊而多增加了两个横跨于车梁体间 的支撑架， 如此造成成本的增加， 且还有占空间的问题， 使大型车辆的一 些大型装置 （管路） 无法设置于此或难以穿过此空间。 另一专利号中国台 湾 M255169 , 虽减少了一个支撑架， 但还是有一个支撑架有占空间的疑虑。
再者， 上述二专利皆仅设有一个用以升降轮轴的气囊， 一个气囊所能 举升的效果较差， 车辆在通过弯度较大的转弯时， 车轮仍有摩擦到地面的 风险， 且由于一个顶撑板搭配两个连动杆已占据相当的体积， 因此也无法 再增设另一组升降装置来提升举升效果。
又， 当该车辆在载运重物且行进于颠簸路段的时候， 由于整个车体非
常沉重， 在上下晃动的过程中， 该用以升降轮轴的气囊会有可能被顶撑板 压扁， 进而造成顶撑板不断撞击支撑架的情形发生， 且更可能造成气囊遭 受大力挤压而发生破裂的问题。 同样地， 该避震用的气囊也会因为在晃动 过程中， 因为轮轴上下移动的距离过大， 而使其遭受过度拉扯而有变形的 疑虑。
再来， 该二专利所揭示的车辆轮轴升降装置皆无法做适度的调整， 由 于每一种车款的轮轴与车体的间距皆不同， 因此必须针对每一车款量身订 作， 如此势必增加制作上的成本。
发明内容
本发明的主要目的是提供一种整体体积小且举升效果佳的车辆轮轴升 降装置。
为达成上述目的， 本发明的车辆轮轴升降装置供装设于一车辆上， 该 车辆包括一车架组与多组车轮组， 该车架组包括至少二梁体， 且各该车轮 组包括一轮轴， 该车辆轮轴升降装置包含二举升结构， 该二举升结构分别 包括一固定部及一可动部， 各所述固定部固设于各该梁体上， 各该可动部 一端设于各所述固定部， 另端可移动地设于该轮轴；
其中， 该二举升结构围构形成一容置空间；
其中， 各所述可动部供上下移动该轮轴， 使该轮轴可相对该车架组上 下移动于一第一位置与一第二位置之间。
本发明之车辆轮轴升降装置以该固定部直接取代先前技术的支撑板， 且因为固定部的体积小于支撑板， 据此， 使该二举升结构之间的容置空间 较大于先前技术， 使本发明之车辆轮轴升降装置可达成较先前技术不占空 间的优点， 令大型车辆的大型装置 （零件） 可设置于此空间或较容易穿过 此空间， 且还可将轮体举升的较先前技术更高的位置， 并还可达成更为稳
固的举升功效。

具体实施方式
以下将以较佳实施例说明本发明的
请参考图 1、 图 2及图 4， 本发明的车辆轮轴升降装置供装设于一车辆 上，该车辆包括一车架组与多组车轮组，该车架组包括两根梁体 111、 11Γ，
较佳者， 梁体 111、 111' 分别具有一顶板 112、 112'、 一连结板 113、 113' 及一底板 114、 114' , 各该连结板 113、 113' 设于各该顶板 112、 112' 与 各该底板 114、 114' 之间， 更明确地说， 该两根梁体皆呈工字形， 当然， 在其他可能实施例中， 所述的梁体也可是其他形状。 再者， 各车轮组包括 一轮轴 121及两轮体 122， 该二轮体 122设于轮轴 121两端， 该车辆轮轴 升降装置包含二举升结构、 二避震机构及一气压控制部件。
该二举升结构分别包括一固定部 21、 21'及一可动部，各该固定部 21、 21' 固设于该梁体 111、 111' , 较佳者， 各固定部 21、 21' 设于各该底板 114、 114' 上端， 各该固定部 21、 21' 呈一座体状， 各该可动部一端设于 各该固定部 21、 21'， 另端可移动地设于该轮轴 121。 其中， 该二举升结构 围构形成一容置空间 23， 该容置空间 23供该车辆的零件穿设。 其中， 各 该可动部供上下移动该轮轴 121， 使该轮轴 121 可相对该车架组上下移动 于一第一位置与一第二位置之间。 在本实施例中， 各可动部分别包括一第 一气囊 221、 221'、 一顶撑板及一连动件 223、 223' , 各该第一气囊 221、 221' 分别设于各固定部 21， 21' 上， 各该顶撑板设于各该第一气囊 221、 221' 顶端， 各该连动件 223、 223' 设于各该顶撑板与该轮轴 121之间。 较佳者， 该二顶撑板相互连结形成一体板状结构的板体 222。 在本实施例 中， 各该连动件 223、 223' 包括一调整部及一连接部， 该连接部固设于该 轮轴， 该调整部设于该连接部与各该顶撑板之间； 其中， 该调整部可相对 该连接部上下移动来调整其延伸之高度， 并随时定位于任一高度。 再者， 该二固定部 21、 21' 分别包括一挡止件 224、 224'， 该二挡止件 224、 224' 自各该固定部的底部向上延伸一段高度。 较佳者， 各该挡止件 224、 224' 具有一可调部 225、 225' 及一固接部 226、 226' , 该固接部 226、 226' 一 端固设于该固定部， 该可调部 225、 225' 设于该固接部 226、 226' 另端，
且该可调部 225、 225' 可相对该固接部 226、 226' 上下移动来调整其延伸 之高度， 并随时定位于任一高度 （如图 6所示）。
各该避震机构分别设于各该梁体 111、 111' 与该轮轴 121之间， 并用 以辅助各该可动部上下移动该轮轴 121， 在本实施例中， 该二避震机构分 别包括一支撑座 31、 31'、 一悬臂 32、 32'、 一第二气囊 33、 33' 及一油 压缸 34、 34'， 各该支撑座 31、 31' 固设于各该梁体 111、 111' , 各该悬 臂 32、 32' 一端可枢摆地设于各该支撑座 31、 31' , 各该轮轴 121 固设于 各该悬臂 32、 32' 上， 各该第二气囊 33、 33' 固设于各该悬臂 32、 32' 另端与各该梁体之间， 各该油压缸 34、 34' 可枢摆地设于各该支撑座 31、 31' 与该轮轴 121之间， 借此， 当该车辆行进于颠簸路段时， 车体会产生 剧烈的上下晃动， 此时各避震机构的油压缸以及第二气囊的组合可吸收大 部分的晃动力量而提供极佳的减震缓冲效果， 进而保护车体不会产生剧烈 的晃动。
该气压控制部件用以供调控各第一气囊 221、 221' 及各第二气囊 33、 33' 的充气与泄气， 较佳者， 该气压控制部件是一气压控制器及多个管体 (前述二者皆未绘示），其中一部分管体连通于该气压控制器与各该第一气 囊间， 另一部分管体连通于该气压控制器与各该第二气囊间。
请参考图 2及图 3， 本发明的车辆轮轴升降装置可供如大货车或是拖 板车等大型车辆于无载运重物 （空车） 状态时， 可借由该气压控制器， 将 该二第一气囊充饱气， 并同时将该二第二气囊泄气， 此时， 各该第一气囊 在充气状态时， 各该顶撑板上升 （在本实施例已将该二顶撑板一体结合形 成该板体 222 )， 并使各该连动件带动该轮轴上升至第一位置， 此刻， 该轮 轴会带动该二轮体上升并脱离地面， 借此， 该大型车辆其他轮体可以减少 轮胎磨损， 且该大型车辆可减少必须克服轮胎与地面摩擦所耗的能源， 又
可以减少回转半径， 使大型车辆便于回转与方便操作。
请参考图 4及图 5， 当该大型车辆正装载沉重的货物上路时， 可借由 该气囊控制器将该二第一气囊泄气， 并同时将该二第二气囊充饱气， 各该 第一气囊在泄气状态时， 各该顶撑板 （在本实施例已将该二顶撑板一体结 合形成该板体 222 ) 下降并抵靠于各该挡止件， 更明确地说是抵靠于各该 挡止件的可调部， 并使各该连动件带动该轮轴下降至第二位置， 此刻， 该 轮轴会带动该二轮体下降至地面， 借此利用多个轮体来分担重量。
借此， 本发明车辆轮轴升降装置因借由二呈座体状之固定部分别设在 其中一梁体底部上端， 使各该第一气囊可直接设在各该固定部上， 使本发 明的车辆轮轴升降装置以该固定部直接取代先前技术的支撑板， 且因为固 定部的体积小于支撑板， 据此， 使该二举升结构之间的容置空间较大于先 前技术，使本发明的车辆轮轴升降装置可达成较先前技术不占空间的优点， 使大型车辆的零件可设置或较容易穿过此空间。
再者，本发明的车辆轮轴升降装置因整体结构所产生较大的容置空间， 因此可较先前技术有空间设置两个举升机构， 借此， 使本发明的车辆轮轴 升降装置可达成将轮体举升的较先前技术更高的位置， 且还可达成更为稳 固的举升功效。
又， 本发明的车辆轮轴升降装置因在各固定部上设有各该挡止件， 且 该挡止件自各该固定部的底部向上延伸一段高度， 当该车辆在载运重物且 行进于颠簸路段的时候 （轮轴下降至第二位置）， 由于整个车体非常沉重， 因此会产生剧烈的上下晃动， 此时， 各该顶撑板仅会稍微碰撞于该各该挡 止件， 而不会有发生与各该固定部产生大面积碰撞的情事产生， 进而可达 成避免第一气囊遭受大力挤压而发生破裂或变形的功效。 此外， 因为挡止 件间接限制住轮轴向下移动的距离， 因此当遇有路面较大的坑洞时， 可避
免气囊过度拉抻， 造成变形， 而无法正常复位至原来状态。
再来， 当业者欲将本发明装设在任一款车辆时， 由于各款车辆的轮轴 与梁体的间距不同， 请参考图 6， 在本发明中可借由调整挡止件的可调部 的延伸高度来符合各款车辆的轮轴与梁体的间距， 当然也可以借由调整连 动件的调整部的延伸高度或者同时调整上述二者来达到相同之效果，借此， 本发明中的连动件和挡止件作成可任意调整的结构， 使本发明可适用于各 种车辆。
