下面结合附图和具体实施方式对本发明作进一步说明。 附图说明
图 1是本发明滑板转向架的立体分解图；
图 2是本发明装配好了的转向架的一个从下往上看的概略立体图； 图 3是本发明装配好了的转向架的一个从上往下看的概略的立体图。 具体实施方式
在附图中概略地示出了一种滑板转向架。 转向架包括一个第一 （或 上部）底座部份 11， 它通常是一个浇铸件，例如用材料为铝、钛、铝合金、 或镁合金铸成。该转向架还包括一个第二 （或下部）底座部份 12它通常是 一个塑料材料的模制件。该塑料材料可以是尼龙， 或其它具有高强度及良 好表面润滑性的塑料材料。
一个悬架 13通过穿过一个套 15的轴销 14，可转动地连接到该两个底 座部份 11和 12。 安装完成后， 套 15跟悬架 13同时转动， 并提供该悬架 的顺滑作用。
一对弹簧组件 16支持着该悬架 13。
该上部底座部份 11包括第一对孔 17。在该上部底座 11的另一端，有 一对用来接纳紧固件的空腔， 每个空腔具有第二对孔 19中的一个和第三 对孔 20中的一个。
该上部底座部份 11还包括一个孔 21 ,—轴销 14通过该孔穿入并可转 动地固定悬架 13。
因此该第一对孔 17经常用来把该滑板转向架固定在一个滑板平台上， 通常只有该第二对孔 19中的一个， 或第三对孔 20中的一个被使用， 这是 根据使用靠里面的 "新型" 四孔系统还是靠外的 "旧式" 四孔系统而定。
该下部底座部份 12包括一对孔 22它们对准该上部底座部份的该第一 对孔 17。 紧固件穿过该第一对孔 17， 也穿过第二对孔 22。
紧固件不单用来把该转向架 10固定到该滑板平台， 也用来把该下部 底座部份 12固定到该上部底座部份 11。
该下部底座部份 12包括一个平坦的支承板 23用以顶接该悬架 13的 平坦表面 24。当装配好后，该支承板 23相对于该上部底座部份 11的安装 面 33以一个锐角延伸。
螺母 25被拧紧在该轴销 14的螺紋部份上。 该拧紧不单把该悬架 13 拉贴在该支承板 23上，也用来把该下部底座部份 12固定在该上部底座部 份 11上。
在使用时， 该悬架 13以该轴销 14为中心转动， 该平坦表面 24扭曲 顶接该支承板 23，就是在这些表面之间需要良好的润滑。适当挑选该下部 底座部份 12的塑料材料提供了这种特性。适当挑选该下部底座部份 12的 塑料材料也允许该支承板 23 的各外缘在高速急转弯时产生的加压下有一 些挠度， 因此减少了该悬架 13 的转向摆动， 更准确地说提供所须的较大 的稳定性。该螺母 25被收容在该上部底座部份 11的一个螺母凹坑 34中。 该轴销 14的另端有一个内六角坑 35。
在支承板 23的中心区域有一个对准孔 21的孔 26。 一轴套 41插入该 孔 21时要穿过该孔 26。
各弹簧组件 16包括一个外螺旋弹簧 27和一个内螺旋弹簧 28。 帽 29 被插入该外螺旋弹簧 27和该内螺旋弹簧 28的同一端。 该内螺旋弹簧 28 的另端被收容在一个端帽套 30中。 各帽 29和 30都是由典型的润滑性模 塑材料做成， 因而各弹簧不会在压缩和回伸时抓刮各帽而发声。
该外弹簧 27也可以用塑料材料例如氨基甲酸乙酯做成以便具有比螓 旋弹簧更大的吸振性，因此提高了某些滑板使用时的表现，例如下山竞速。 在这情况下， 该些弹簧组件可以是鼓形的、非圆截面的以及侧边有凹槽以 提高转向操控性。
该弹簧帽 29和 30也可以用多个较长的套做成当弹簧压缩和回伸时它 们彼此移进移出就像照相机的镜头变焦系统， 因而约束各弹簧组件沿着一 个基本上是直线的轴线压缩。
各弹簧组件 16有一端被收容在该下部底座部份 12的一个弹簧空腔 31 中， 它的另端被收容在该悬架 13的弹簧空腔 32中。 该两个弹簧组件 16 的各自的纵轴彼此形成锐角。
为了调节转向反应的 "松紧度"及进行中位调节， 提供了一个由多个 弹簧预应力螺母 39和螺钉组成的系统。一个内六角扳头穿过该悬架 13的 小孔 40能拧动该些螺钉。
该悬架 13包括一个同心轴组件 36， 它在各端都有一个螺纹部份 37 用来接纳一个锁紧螺母从而把轮子固定。该轴组件能和该悬架一体浇铸出 来因而能用和该悬架相同的或相似的材料做成， 例如通常用铝、 钛、 铝合 金或镁合金。 为了使该轴组件有更高的强度， 高强度的嵌件轴芯 38能被 贯通该轴组件并进入该悬架的主体部份。应该只用一条连续的嵌件轴芯 38 贯穿整个轴组件。 也可以是， 可以采用两个分开嵌件轴芯 38伸入该悬架 体各端一部份的深度。 该些嵌件轴芯例如都通常是用高强度弹簧钢制成。
该轴组件还能包括一个位于其中部的不规则部份 -例如一个弯曲、 扁平的部份或一组凸筋或环 -这防止它从该悬架内剥落或旋动。
必须指出的是滑板转向架的设计、制造和使用由本技术领域的普通技 术人员对本发明做出的显而易见的改进和改变都将被认为没有超出本发 明的范围。 例如， 该支承板 23从该安装面 33伸出的角度， 虽然对于滑板 动力学来说很重要， 但对于本发明来说却不重要， 从而可以和本发明附图 所示的不同而并不偏离本发明的范围。 工业实用性
本发明的滑板转向架， 由于其底座是由两部分构成的， 所以本发明底 座上的安装孔能够布置成适用于任何四孔系统。 同时， 本发明转向架的底 座提供了一个与滑板平台结合的大的支撑面， 依靠该面， 当滑板使用者通 过侧倾滑板平台来使得滑板转向时， 该转向架的悬架能在使用中转动， 使 得转向功能更加灵活。
