Description

一种车轮螺母
技术领域
本实用新型涉及一种汽车用的紧固件，特别是涉及一种车轮螺母。
背景技术
车轮是汽车行驶系统中的重要部件，主要作用是支撑整车，缓冲由路面传来的冲击保持车辆平衡性，并通过轮胎同路面之间的附着力产生驱动力和制动力等。在汽车行驶过程中，车轮可能因为各种原因需要被更换，而每次更换都需要将连接轮辋和轮毂的汽车车轮螺母拆卸下来，这样往复拆卸、再安装拧紧，会造成车轮螺母的变形、松动，甚至出现螺母黏附套筒等问题，以致车轮螺母脱落而造成安全隐患。
因此本领域技术人员致力于开发一种不易变形的车轮螺母。
实用新型内容
有鉴于现有技术的上述缺陷，本实用新型所要解决的技术问题是提供一种车轮螺母，其能够解决现有车轮螺母多次使用后变形、松动的问题。
为实现上述目的，本实用新型提供了一种车轮螺母，包括螺母体，螺母体的外表面是由多个圆弧面构成，圆弧面的圆弧方向外，圆弧面的半径大于螺母体外表面的外切圆半径。
较佳的，圆弧面共六个，且结构相同，螺母体截面的外形呈六边形，圆弧面弧形的最高点为螺母体每边的中点。
较佳的，六个圆弧面之间采用倒圆连接。
较佳的，圆弧面的半径比螺母体外表面的外切圆半径大20mm-30mm。
较佳的，螺母体的上方设有螺母盖。
较佳的，螺母体与螺母盖之间通过翻铆方式连接。
本实用新型将现有的车轮螺母的平面设计为圆弧面，增大了车轮螺母与套筒之间的接触面积，增大了车轮螺母的受力面积，进而有效的避免了车轮螺母变形、松动的问题，提高了车轮螺母的使用寿命。
附图说明
图1是本实用新型一具体实施方式的结构示意图；
图2是图1中B-B方向剖视结构示意图；
图3是本实用新型的使用状态参考图；
图4是图3中F处的放大结构示意图；
图中：1-螺母体；2-圆弧面；3-螺母盖；5-套筒；6-现有设计中的螺母体；R1-圆弧面的半径；R2-螺母体外表面的外切圆半径；A-圆弧面弧形的最高点。
具体实施方式
下面结合附图和实施例对本实用新型作进一步说明，需注意的是，在本实用新型的描述中，术语“上”、“下”、“左”、“右”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本实用新型和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方式构造和操作，因此不能理解为对本实用新型的限制。术语“第一”、“第二”、“第三”等仅用于描述目的，而不能理解为指示或暗示相对重要性。
如图1至图2所示，一种车轮螺母，包括螺母体1，螺母体1的外表面是由六个相同的圆弧面2构成，圆弧面2为向外凸出的圆弧面，圆弧面2的半径R1大于螺母体1外表面的外切圆半径R2，较佳的，圆弧面2的半径R1比螺母体1外表面的外切圆半径R2大20mm、21mm、22mm、23mm、24mm、25mm、26mm、27mm、28mm、29mm、30mm；螺母体1截面的外形呈六边形，圆弧面2弧形的最高点A为螺母体1每边的中点。
通过将螺母体的外表面设计为圆弧状，使得用套筒5拆卸螺母时，增大了套筒与螺母体六个面的接触面积，增大了螺母体的受力面积和抗压能力，进而有效的避免了螺母体因受力面积小，而使得螺母体变形或螺母拧不紧的问题。另外，还可将螺母体1的六个圆弧面的连接部分设计为倒圆角，进一步增大螺母体与套筒之间的接触面积，降低螺母体变形的风险，提高了螺母体的使用寿命。
螺母体1的上方设有螺母盖3，螺母体1与螺母盖3之间通过翻铆方式连接，一方面美化了螺母的外观，另一方面防止泥土等物质进入车轮螺栓和车轮螺母之间，保持了车轮螺栓和车轮螺母之间的洁净，进一步提升螺母的使用寿命。
如图3至4所示，使用时，套筒5套设在螺母体1外侧，然后旋转套筒5，套筒5与螺母体1的圆弧面2的接触部分为面；若是现有设计中的螺母体6，则套筒5与螺母体1之间的接触点为线，故本实用新型大大提升了螺母体1与套筒5的接触面积，提升了螺母体的受力能力，达到了提高螺母体使用寿命的效果。
以上详细描述了本实用新型的较佳具体实施例。应当理解，本领域的普通技术人员无需创造性劳动就可以根据本实用新型的构思作出诸多修改和变化。因此，凡本技术领域中技术人员依本实用新型的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案，皆应在由权利要求书所确定的保护范围内。
