本发明还提供一种自行车, 其采用上述自行车振动能量转化机构。
相对于现有技术, 本发明具有的技术效果是:
1 ) 本发明的自行车振动能量转化机构, 利用传力机构、 传动臂及摆臂将摆 动车架的摆动转化为输入齿轮的转动,输入齿轮利用第一棘轮机构将其往复转动 转化为发条的单向上紧, 从而将摆动车架的振动能量积聚于发条内, 发条利用单 正向转动, 从而将自行车的振动能量经过积蓄后再转化为自行车前进的动能, 提 高了转化后的驱动力, 充分利用了路面的振动能量并节省了骑车人的体力, 同时 通过该振动能量的转化, 减少了传导至自行车座椅的地面振动幅度,提高自行车 的行驶舒适性;第二棘轮机构用于防止已上紧的发条的内端在处于发条上紧间歇 时反向转动, 从而使发条松开。
2) 当自行车需要倒车时, 拉动连接杆并使接合套与从动齿轮分离, 防止倒 车时链轮反向转动时、通过单向离合器驱动发条的外端反向转动, 从而使发条被 上紧至极限而损坏, 当倒车过程结束后驱动连接杆回位,接合套与从动齿轮重新 接合并连接从动齿轮与转动轴。
3)第三棘轮机构用于保证踏板轴单向驱动链轮转动, 当踏板轴反向转动时, 切断踏板轴与链轮之间的动力传递,另外当自行车下坡等工况下链轮的转速过快 时, 切断链轮与踏板轴之间的动力传递;链齿轮与接合套之间设有的压縮弹簧将 接合套压紧于从动齿轮上, 防止两者在振动作用下自行脱离。
4) 所述各棘轮机构与单向离合器都起到单向驱动或单向分离的作用, 相比 棘轮机构、 单向离合器采用滚珠结构, 工作时更安静。
5) 台阶轴与发条的内端相连接, 适于在发条的内端与其它传动部件之间传 递动力, 其结构紧凑, 占用空间小, 通过轴承配合于固定轴上, 工作更平稳、 安 静; 摆臂由上摆臂与下摆臂两段结构組成, 相比采用单一结构, 减小了臂形结构 及弧形面齿的加工难度, 同时提高摆臂在外壳内的安装精度,提高了弧形面齿与 输入齿轮的啮合精度。
6) 自行车振动能量转化机构的工作方法中, 当骑车人正常骑车时, 踏板轴 驱动链轮正向转动, 同时摆动车架的振动能量被传递至车轮上驱动自行车前行; 当链齿轮正向转动的转速过快或骑车人反向驱动踏板轴时,切断链齿轮与踏板轴 的动力传递; 当骑行速度较快时, 单向离合器切断发条外端与链轮之间的动力传 递, 防止发条的外端正向转动速度过快而使发条松驰;倒车前分离接合套与从动 齿轮, 切断链轮与发条外端之间的动力传递, 防止发条的外端反转而使发条上紧 至极限状态而锁死。
7) 采用上述自行车振动能量转化机构减少了地面传导至座椅的振动, 舒适 性更佳, 同时在减少了骑行过程中人的驱动力, 节省了体力, 增加骑行的距离。 附图说明
