附图说明
下面结合附图详述本申请的具体结构
图1为本申请一种车辆的示意图；
图2为本申请一种车辆的一变径轮结构示意图；
图3为本申请一种车辆的另一种变径轮结构示意图；
图4为本申请一种车辆的再一种变径轮结构示意图。
图中，1-车架、2-前轮、3-变径轮、31-轮边、32-转轴、33-轴心、34-轮径、35-最短轮径、4-后轮、51-轮边、52-最长轮径、53-轴心、54-最短轮径、61-轮边、62-最长轮径、63-轴心、64-最短轮径。
具体实施方式
为详细说明本申请的技术内容、构造特征、所实现目的及效果，以下结合实施方式并配合附图详予说明。
结合附图1，在一具体实施例中公开了一种车辆，包括设置于车辆底部的车轮组，车轮组中包括有变径轮3。车轮组自然是设置于车辆的底部，用以通过车轮组车轮自身的旋转带动车辆行进，如常规的四轮汽车，其四个车轮就构成了该车辆的车轮组。本申请中的车辆，其主要创新的技术点在于变径轮的设计，即在常规的车轮组中增设有变径轮，变径轮即为轮径可变化的车轮，轮径则为车轮的旋转中心(轴心)到与之最近的轮边之间的距离。对于常规的圆形车轮而言，轮径即为圆形车轮的半径，为一固定值。车轮轮径的大小直接关系着车辆跨越梯坎等障碍物的能力，影响着车辆对路面的适应性。由于该车辆中变径轮的设计，使得车辆运行中，通过变径的协助，从而可以轻易适应不同的行驶场景，如越过梯坎，爬楼梯。
再结合附图1，所述车轮组还包括前轮2和后轮4，所述变径轮3位于前轮2与后轮4之间。当然，还包括车架1之类的作为车辆的常规结构，此处不再进行赘述，仅重点阐述创新技术点。变径轮3位于前轮2和后轮4之间，在较为平坦的路面行驶时，可以仅利用前轮2和后轮4工作，而变径轮3此时不工作而不与路面接触，则此种状态下，该车辆与常规车辆无异。而遇到梯坎等行驶障碍时，若仅仅是依靠前轮2和后轮4的配合，难以越过这些障碍，则可以同时利用变径轮3轮径的变化来跨越这些障碍，适应多种行驶路面。且车轮作为车辆的基本结构，为保证车辆稳定，自然是前轮、变径轮、后轮都左右对称设置为宜，如设置有两个前轮、两个变径轮、两个后轮。
在一具体实施例中，所述变径轮3的轮径随着转动角度的变化而逐渐变化。
所述变径轮3的轮径最小值小于所述前轮2的轮径，变径轮3的轮径最大值大于前轮2的轮径。在常规状态下，由前轮2和后轮4来正常行驶，变径轮3置于最小轮径朝下，不接触路面。而在需要通过梯高高于前轮2半径的楼梯等特殊路面时，变径轮3转动开始工作，因所述车辆的重心位于所述后轮4与所述变径轮3之间，当变径轮3转动到开始接触到地面，前轮2抬起，在后轮4和变径轮3推动下，推动车辆跨上台阶，如此反复。
结合图2、图3，在一具体实施例中，以所述变径轮的最短轮径为基准，旋转角度为0～180°时，轮径从最小值连续变化至最大值，旋转角度为180°～360°时，轮径从最大值连续变化至最小值。
且图2中的变径轮整体为一圆形，变径轮的旋转中心位于变径轮的圆心与轮边31之间。圆心为圆形变径轮的几何中心，而轴心33则是变径轮旋转过程中实际的旋转中心，当然轴心33处对应有转轴32。变径轮的最短轮径35与变径轮的任意轮径34之间的夹角为α，当α为0或360°时，轮径34最小，当α为180°时，轮径34最大。且α为0～180°时，轮径34从最小值逐渐连续变化到最大值，而当α为180°～360°时，轮径34从最大值逐渐连续变化到最小值。且优选的，所述变径轮的最短轮径35为圆形变径轮半径的一半。优选的，所述前轮、变径轮、后轮整体的形状规格相同。
而图3中的变径轮，整体则不是一个标准的圆形。该方案中，包括轮边51，最 长轮径52，轴心53和最短轮径54。其角度变化与轮径变化间的关系与图2中方案相同。即最短轮径54与最长轮径52间的夹角为180°。
结合图4，在一具体实施例中，变径轮包括轮边61，最长轮径62，轴心63和最短轮径64。以所述变径轮的最短轮径64为基准，旋转角度为0～240°时，轮径从最小值连续变化至最大值，旋转角度为240°～360°时，轮径从最大值连续变化至最小值。即在本方案中，夹角为240°时取得轮径最大值。240°相当对于前述方案中的180°，优点是把车辆抬高过程分布在更长的轮边弧度上，相同车重情况下，抬升时发动机所需最大输出功率较小。
需要说明的是，本申请中的轮径是指车轮的轮边(若车轮为圆形，轮边则为圆周)上任意一点到车轮旋转中心的距离。此处，上、下、左、右、前、后只代表其相对位置而不表示其绝对位置。以上所述仅为本申请的实施例，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
