Description

具有离合传动作用系统的自行车 技术领域 本发明涉及一种自行车， 具体涉及一种具有离合传动作用系统的自行车。 背景技术
—般现有的自行车传动方式， 主要是利用圆周式踩踏方式驱动后轮转动。 如 图 1所示， 曲柄 1一端连结在车架 2上， 而另一端套接一踏板 3 , 当使用者踩踏 踏板 3进行圆周式转动时， 则由该曲柄 1带动齿盘 4转动， 并由啮接于齿盘 4上 的链条 (图中未示）同步带动设于车架 2后方位置的飞轮 5转动， 由飞轮 5带动后 轮 6转动， 从而使自行车运动。 然而， 由于此种传动方式的力矩主要来自于使用 者踩踏在蹯板上的施力， 然后由曲柄的力臂转换而成， 而曲柄的长度有限， 因此 此种传动方式所能产生的力矩较小， 所以会消耗人的体力大。
有鉴于上述的问题， 已研发出一种较为省力的自行车， 专利名称为： 一种自 行车其踩动装置 （中国台湾申请号 95216760、 美国申请案号 11/580，298、 欧盟申 请号 06025071.9)。
上述中国台湾第 95216760号专利申请案， 主要是利用了在齿盘与曲柄间增设 一类似套筒板手的构件增长了力臂， 当使用者踩踏踏板进行圆周运动时， 该套筒 板手与曲板连结的一端会进行上、 下的往复摆动， 再由套筒板手的另一端带动齿 盘转动。 如此一来， 在施于相同施力于踩踏上时， 便能由套筒板手增加力臂的长 度， 而使得增加施于齿盘上的力矩， 以此达到省力的功效。
但此种结构仍存在问题， 由于套筒板手受踏板圆周运动的带动， 所以无论踏 板正转或逆转， 套筒板手都是同样的上、 下往复摆动， 带动后轮前进， 因此后轮 无法后退， 只能单向前进运动， 所以， 上述的自行车只能前行而不能后退， 这种 自行车对使用者而言有着使用上极为不便利的问题。 发明内容 本发明的目的在于提供一种具有离合传动作用系统的自行车， 自行车可节省 所需踩踏的施力和适度进行传动系统的离合作用。

上述即为本发明所提供具有离合传动作用系统的自行车 1 0 0的各部构件及 其相关连结方式介绍， 接着再将其使用特点介绍如下：
首先， 请参阅第 4图所示， 当正常传动而驱动后轮 3 0转动时， 即将离合装 置 4 4作用件 4 4 4的调整部 4 4 8由使用者进行远端控制而位移至结合位置 上， 使该结合件 4 4 2上的凸柱 4 4 5插入齿盘 4 2 2的结合孔 4 2 4中， 使齿 盘 4 2 2与结合件 4 4 2结合而被传动轴 4 2 1所带动并旋转， 如此一来， 齿盘 4 2 2上的链条 (图中未示)便可随之带动该后轮 3 0转动。
接着， 请参阅第 5图所示， 当将传动轴 4 2 1与后轮 3 0形成互不带动的状 态时 (如进行自行车后退、 牵车或其它无须带动连动杆 4 3 3摆动时)， 则可由使 用者进行远端控制而将该结合件 4 4 4的调整部 4 4 8移位至释放位置上， 使该 结合件 4 4 2上的凸柱 4 4 5一起被拉离齿盘 4 2 2的结合孔 4 2 4外， 如此一 来， 该齿盘 4 2 2便可不再随传动轴 4 2 1的转动而转动， 便能使得连动杆 4 3 3在无须摆动的情况下， 进行自行车的行进 (如后退、 牵车的状态）， 以解决使用 上不便利的问题。
本发明虽由前述实施例来描述， 但仍可变化其形态与细节， 在不脱离本发明 的精神下制作。 前述为本发明最合理的使用方法， 仅为本发明可以具体实施的方 式之一， 但并不以此为限。
