Description

结构改进的碳纤维轮圈 技术领域
本发明涉及到碳纤维轮圈结构，尤其是涉及到自行车碳纤维轮圈 辐条組装结构。
背景技术
现有带内胎的自行车碳纤维轮圏的截面图如图 1所示，轮圈 1由 半封闭的胎位槽孔 10和封闭的腔室 11组成， 二者上、 下排列， 轮圈 半封闭的胎位槽孔 10和封闭的腔室 11的壁体由碳纤维层一体成形， 胎位槽孔 10用于卡设、容纳内胎，腔室 11底部壁体间隔的加工成供 辐条螺母 3穿过的过孔，辐条螺母的小端穿过过孔与辐条末端锁紧固 定， 辐条的另一末端固定在花毂上； 为增加过孔周围壁体的强度， 避 免周围壁体在使用过程中出现裂纹、破损影响自行车的强度、轮圈的 使用寿命，设计者在腔体底部过孔周边加设金属垫片， 以增加过孔周 边壁体的强度， 如图 2所示。 因此为了增加过孔周围壁体的强度， 所 采取的方式是腔体底部加厚为圆弧形， 且加设金属垫垫片， 可这样包 覆碳纤维层纱工艺较复杂， 时间较长， 装配速度緩慢， 组装效率低。
尤其是在组装辐条时效率更低，如图 3可知， 为了将辐条螺母装 在过孔中，一般会借助细铁丝做为引线， 将辐条螺母逐个装设在若干 个过孔中， 这种装配速度非常慢、 耗时， 效率低， 而且由于辐条作用 在轮圈的力仅限于轮圈单一内侧，即腔室的底部壁体，轮圈容易变形， 影响轮圈的使用寿命及性能。 发明内容
本发明提供一种可让轮圈受力均衡、 强度高， 装配速度快、 缩. 短生产时间、 效率高， 降低成本的结构改进的碳纤维轮圈。
本发明解决其技术问题所采用的技术方案是： 结构改进的碳纤 维轮圈， 包括轮圈本体和若干个铝套，轮圈本体设有半封闭的胎位槽 孔及封闭的腔室， 二者上下排列，轮圈本体的胎位槽孔及腔室的壁体 由碳纤维层一体成形，胎位槽孔底部壁体与封闭的腔室底部壁体设有 若干个等分的、 相对应的内、 外定位孔； 每个铝套设定在内、 外定位 孔之间， 并与内、 外定位孔的壁体固定连接， 铝套中间还设有阶梯通 孔。
所述的轮圈本体，其半封闭的胎位槽孔底部壁体设置的内定位孔 为阶梯孔； 其封闭的腔室底部壁体为平面，在此壁体设置的外定位孔 为通孔。
所述的轮圈本体，其半封闭的胎位槽孔底部壁体加厚。壁厚增加， 加强了轮圈强度， 减小壁体受力后的变形。
所述的铝套顶部外缘设有与轮圈本体内定位孔相配的凸台；内部 中间设有阶梯通孔， 阶梯通孔的大孔容纳辐条螺母， 辐条螺母小端从 阶梯通孔的小孔穿过与辐条的一端锁固；铝套底部外径小于铝套本体 外径， 并固定设置在外定位孔内。 这样铝套受到辐条的作用力时， 会 将力分散到轮團本体的壁体上， 使轮圈的受力均匀， 不易变形， 增加 了轮圈的使用寿命。
采用上述结构后， 与背景技术相比有以下优点：
其一、 由于轮圈本体其封闭腔体的底部壁体为平面， 且不需要设 置金属加强片， 这样不但筒化了生产本体的缠纱工艺， 减少了生产时 的加工工艺， 节省了时间、提高了效率； 也减少了价格昂贵的碳素纤 维的使用， 降低了成本；
其二、 由于铝套设置在轮圏本体内、 外定位孔内， 其上凸台卡设 在内定位孔的阶梯孔的大孔内，铝套底部小端设置在封闭腔本底部外 定位孔内， 因此装设在铝套内的辐条螺母受到辐条的拉力时， 铝套会 将力传递给本体的上、 下壁体上， 让轮圈本体所受的拉力均衡分散， 减少长久受力变形的影响， 让辐条有更强的着力点；
其三、 由于铝套的通孔是容纳辐条螺母， 也就是说当铝套与轮圈 本体粘接装配后， 将辐条螺母穿过铝套的阶梯孔， 就可以与辐条相配 锁固， 不需要用引线穿入， 这样组装辐条时提高了装配效率， 节省了 时间。
以下结合附图及实施例对本发明作进一步详细说明； 但本发明的 结构改进的碳纤维轮圈不局限于实施例。

图 8为本发明碳纤维轮圈组装辐条后的剖面结构示意图； 图 9为本发明碳纤维轮圈本体末加工的结构示意图。
具体实施方式
实施例， 结构改进的碳纤维轮圏， 如图 4、 图 7所示， 包括轮圈 本体 1和若干个铝套 2 , 轮圏本体 1设有半封闭的胎位槽孔 10及封 闭的腔室 11 , 二者上下排列， 轮圈本体的胎位槽孔 10及封闭的腔室 11 的壁体由碳纤维层一体成形， 胎位槽孔底部壁体 100与封闭的腔 室底部壁体 110设有若干个等分的、相对应的内 101、外 111定位孔； 每个铝套 2设定在内 101、 外 111定位孔之间， 并与内 101、 外 111 定位孔的壁体固定连接， 铝套 2中间还设有阶梯通孔 22。
如图 5所示， 所述的轮圈本体 1 , 其半封闭的胎位槽孔底部壁体 100设置的内定位孔 101为阶梯孔； 其封闭的腔室底部壁体 110为平 面，在此壁体设置的外定位孔 111为通孔； 所述的半封闭的胎位槽孔 底部壁体 110加厚，这样则增加了轮圈强度，减小壁体受力后的变形。
如图 6所示，所述的铝套 2顶部外缘设有与轮圈本体 1内定位孔 101相配的凸台 21; 内部中间设有阶梯通孔 22， 阶梯通孔的大孔 224 容纳辐条螺母 3， 辐条螺母 3小端从阶梯通孔的小孔 225穿过， 并与 辐条 4的一端锁固； 铝套底部 221外径小于铝套本体 222外径， 并固 定设置在外定位孔 111内。这样铝套 2受到辐条 4的作用力时，会将 力分散到轮圈本体 1的壁体上， 使轮圈的受力均匀， 不易变形， 增加 了轮圏的使用寿命。 采用上述结构后， 如图 8、 图 9所示， 由于轮圏本体 1其封闭 腔体 11的底部壁体 111为平面， 且不需要设置金属加强片 5 , 这样 简化缠纱工艺及加工工艺， 节省了时间、提高了效率； 也减少了价格 昂贵的碳素纤维的使用，降低了成本；同时也减轻轮圈本体 1的重量； 由于铝套 2的通孔 224是容纳辐条螺母 3， 也就是说当铝套与 2轮圈 本体 1粘接装配后， 将辐条螺母 3穿过铝套 2的阶梯孔 22， 就可以 与辐条 4相配锁固， 不需要用引线穿入，这样组装辐条 4时提高了装 配效率， 节省了时间。
以上所述，仅为本发明较佳实施例而已， 并非以此限制发明实施 范围， 凡熟悉此项技术的人士， 即依本发明申请专利范围及说明书内 容所作的等效变化与 饰， 皆应仍属本发明专利涵盖的范围内。
工业实用性
本发明结构改进的碳纤维轮圏， 在轮圈本体内间隔的设置铝套， 将辐条螺母穿过铝套的阶梯孔， 就可以与辐条相配锁固， 不需要用引 线穿入， 这样组装辐条时提高了装配效率， 节省了时间具有良好的工 业实用性。
