我国汽车行业经过几十年的发展，己成为国民经济的一个重要产业。随着技术的进步，汽车各项性能指标的提高，世界各国政府对节能、环保的要求也日趋严格。所以，汽车轻量化己成为汽车发展的主要方向，汽车一般部件重量减轻1%，可以节油1%，运动部件重量每减轻1%，可以节油20%。汽车轮毂是装在汽车上用来支撑轮胎的部件，汽车轮毂作为汽车最重要的运动部件之一，对其的性能，重量，实用寿命都有很高的要求。目前轿车的轮毂结构一般包括轮稠和轮辐，业界提出采用碳纤维材质一体制成的车轮轮毂，碳纤维“外柔内刚”，质量比金属铝轻，但强度却高于钢铁，在同等动力下，碳纤维轮毂的制动性能比铝合金轮毂更灵敏，减震效果更好，并且油耗更低。
 技术问题
碳纤维轮毂制造是用模亚成型或材料预成型技术，出模后产品的厚度有部分不均匀，为了保留碳纤维的纤维完整性，不均匀的厚度无法像金属材料一样进行机加工的精细化平整，那么因此将导致轮毂安装入的平衡问题，影响行驶。同时用碳纤维制成的轮毂，安装进汽车轮毂轴承上，需要反复多次安装，如果是碳纤维复合材料，安装螺丝孔，将被磨损并导致安装的平衡问题，影响驾驶及安全；另，两片式碳纤维汽车轮毂在轮惘及辐条螺丝的锁合处，需要锁牢，若将螺丝拆下，碳纤维的螺孔会被磨损，二次锁固时，达不到锁固要求，影响汽车的行驶安全。因此现有的碳纤维轮毂的装配强度不够高，并且轮惘及轮辐在分离后无法进行二次锁附。同时，现有的轮毂的外圆过于厚重，使轮毂毛坯铸造浪费材料，增加了制造成本，且不符合轻量化的要求。
 技术解决方案
本发明的目的在于提供一种碳纤维汽车轮毂结构，能够加强碳纤维轮辋、碳纤维轮辐之间的连接强度，还能够减轻轮毂的重量，提升汽车使用操作性，降低汽车能耗。
为实现上述目的，本发明采用以下技术方案：一种碳纤维汽车轮毂结构，包括碳纤维轮辋和碳纤维轮辐；所述碳纤维轮辋具有一硬压成型的第一连接区域，所述第一连接区域用于连接碳纤维轮辐；所述第一连接区域沿着自身厚度方向贯穿设置有第一连接孔；

所述第一连接区域和第二连接区域相向的一侧涂覆有粘黏物质，所述碳纤维轮辋、碳纤维轮辐依靠螺钉和粘黏物质固定连接在一起。
进一步地，上述碳纤维轮毂结构还包括毂体和辐条，所述毂体设有轴向中心通孔，轴向中心通孔用于安装内、外轴承及车轴；
所述辐条的一端连接毂体，另一端连接碳纤维轮辋；所述碳纤维轮辋沿着周向设置有沿着径向内凹的胎槽，用于安装车胎；所述胎槽的槽底内设有沿着轴向延伸的第一空腔，所述第一空腔将胎槽的槽底分为位于胎槽和第一空腔之间的第一部分，以及位于第一空腔外的第二部分；所述第一部分的厚度大于第二部分的厚度；
所述辐条内沿着其自身长度方向延伸设置有第二空腔；所述第二空腔将辐条内壁分为第二空腔两侧的侧壁，以及第二空腔顶部的顶板和底部的底板；所述两侧的侧壁、底板的厚度均大于顶板的厚度。
进一步地，所述第一部分的厚度为3-5mm，第二部分的厚度为0.5-1.5mm。

 本发明的最佳实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。
一种碳纤维汽车轮毂结构，包括碳纤维轮辋1、碳纤维轮辐2、毂体3和若干辐条4，碳纤维轮辋1具有一硬压成型的第一连接区域11，第一连接区域11用于连接碳纤维轮辐2，第一连接区域11沿着自身厚度方向贯穿设置有第一连接孔12；碳纤维轮辋1的第一连接区域11采用硬压成型，保证碳纤维轮辋1有足够的强度和精准的粘合尺寸。
碳纤维轮辐2具有与第一连接区域11对接的第二连接区域21，第二连接区域21具有与第一连接孔12对应的第二连接孔22。碳纤维轮辐2采用中空吹气成型，这样可以提高碳纤维轮辐2的强度并减轻重量，碳纤维轮辐2的壁厚为6mm-20mm。
碳纤维轮辐2在第二连接区域21远离第一连接区域11的一侧具有预埋金属件23，预埋金属件23由远离第二连接区域21的一侧向着靠近第二连接区域21的方向设置螺纹孔24，螺纹孔24连通至第二连接孔22。预埋金属件23在碳纤维轮辐2吹气成型时就预埋在碳纤维轮辐2内部了，螺纹孔24在碳纤维轮辐2成型后，再通过攻牙生成。
一螺钉25穿过第一连接孔12和第二连接孔22后与螺纹孔24固定连接，螺钉25的规格为M6。螺钉25的螺帽与第一连接孔12的连接缝隙处填充密封胶26，密封胶26的作用是固化螺钉25与螺纹孔24之间的螺纹连接，使得螺钉25不会松脱，并且将螺纹连接处进行密封，密封胶26为高温下固化的胶水，如高温胶。螺帽的外表面包覆一层纱层27，砂层27的厚度为0.5mm，砂层27的作用在于将螺钉25的螺帽遮盖，比较美观，并且可以对螺帽起到密封的作用。
为了进一步增加第一连接区域11和第二连接区域21的连接强度，第一连接区域11和第二连接区域21相向的一侧涂覆有粘黏物质28，碳纤维轮辋1、碳纤维轮辐2依靠螺钉25和粘黏物质28固定连接在一起。粘黏物质28为高温下固化粘黏的物质。
毂体3设有轴向中心通孔，轴向中心通孔用于安装内、外轴承及车轴。每一根辐条4的一端连接毂体3，另一端连接碳纤维轮辋2。碳纤维轮辋2沿着周向设置有沿着径向内凹的胎槽29，用于安装车胎，胎槽29的槽底内设有沿着轴向延伸的第一空腔210，第一空腔210将胎槽29的槽底分为位于胎槽29和第一空腔210之间的第一部分211，以及位于第一空腔210外的第二部分212。由于第一部分211直接朝向车胎，承受了很大的外力，因此第一部分211的强度要求要远远高于第二部分212。因此，为了达到这个强度要求，第一部分211的厚度大于第二部分212的厚度，具体来说，第一部分211的厚度为3mm，第二部分212的厚度为1mm。
辐条4内沿着其自身长度方向延伸设置有第二空腔41，第二空腔41将辐条4内壁分为第二空腔41两侧的侧壁42以及第二空腔41顶部的顶板43和底部的底板44。同样的，对于辐条4来说，侧壁42和底板44为受力面，而顶板43为非受力面。因此，两侧的侧壁42、底板44的厚度均大于顶板43的厚度。具体来说，侧壁42、顶板43的厚度为4-10mm，顶板43的厚度为1-4mm。
本实施例中，侧壁42、顶板43的厚度相同。在具体的设计中，也可以将二者的厚度设置为不相同，只要能够满足各自的强度要求即可。
对于胎槽29的槽底、或者辐条4的内壁而言，其在第一空腔210、第二空腔41的四周边界部分都会有一个过渡区域，将第一部分211、第二部分212相连，或者将侧壁42、顶板43和底板44相连。本实施例中，这部分过渡区域的厚度处处相等或不相等，并且厚度为1-5mm。从而将胎槽29的槽底、辐条的内壁在结构上形成一个整体。
本产品为碳纤维材质的汽车轮毂产品，采用碳纤维材料设计、制造汽车轮毂产品，产品结构设计为空心结构，并且通过了VIA及JIS汽车轮毂强度测试标准本产品结构为空心结构，方便碳纤维材料工艺的实现，提升产品外观质量和美观度，并且减轻汽车轮毂重量，提升了使用的舒适性，提升汽车使用操作性及使用能耗。
并且，上述的轮毂产品强度更强，中空结构如同蜂窝材料结构，形成框架特征受力，使得轮毂具有更好的强度值。汽车轮毂使用舒适性更好，碳纤维具有较好的减震吸能功能，可以提升汽车行驶的舒适性。空心结构碳纤维汽车轮毂可以获得外观表面质量更好的效果，比实心工艺效果更好。空心结构碳纤维汽车轮毂生产工艺较实心工艺更稳定更容易生产。
工业实用性
综上，本发明一种碳纤维汽车轮毂结构，碳纤维轮辋1和碳纤维轮辐2通过螺钉25锁固并通过粘胶相连，有效增加了碳纤维轮辋1和碳纤维轮辐2之间的连接强度，保证了整个轮毂的强度。碳纤维轮辋1和辐条4为空心结构，空心结构碳纤维汽车轮毂生产工艺较实心工艺更稳定更容易生产，中空结构如同蜂窝材料结构，形成框架特征受力，使得轮毂具有更好的强度值，同时，减轻了汽车轮毂的重量，提升了使用的舒适性，提升汽车使用操作性及使用能耗。
以上所述，仅为本发明较佳的具体实施方式，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。
