Abstract

一种偏心链轮自行车。偏心链轮及其右曲柄和中轴辊的连接孔位,选在偏离现有自行车链轮中心处,偏离现有自行车链轮齿顶圆心处。偏心链轮直径适当缩小。偏心链轮和飞轮之间的车架上,装有链条幅度随偏心链轮转动位置不同变化的跟踪调节器,构成偏心链轮自行车的驱动系统。偏心链轮转动一圈的过程中,被驱动链条受力不相等,由小到大,由大到小周期变化,形成旋转加速冲击力,驱动自行车行驶剩力,快速、效率可提高20%。

Description

偏心链轮自行车
本发明涉及的技术领域——人力脚踏车。
现有自行车链轮及其右曲柄和中轴棍的连接孔位，选在链轮齿顶园心，选在链轮中心。链轮旋转一圈的时间过程中，每一个齿作用在链条上力的距离相等，都等于半径。
本发明目的：是提供一种偏心链轮自行车。该偏心链轮及其右曲柄和中轴棍的连接孔位，选在偏离现有自行车链轮齿顶园心处，选在偏离现有自行车链轮中心处。偏心链轮旋转一圈的时间过程中，每一个齿作用在链条上力的距离不相等，周期性变化。
本发明的技术方案是：把现有自行车的中心链轮改为偏心链轮，偏心链轮和飞轮之间的车架上，装有链条幅度跟踪调节器，构成偏心链轮自行车。
本发明的运动方式是：偏心链轮旋转一圈的过程中，被驱动链条受力不相等，由小到大，由大到小周期性变化。由于偏心链轮旋转一圈的过程中位置在不断变动，链条上、下、长、短幅度随之变动。为了保证链条正、反转都处于正常运动状态，设计了链条幅度跟踪调节器。
本发明的优点是：偏心链轮合理运用平衡中的不平衡，驱动过程更加有利于人体运动生理性能，偏心链轮转动过程中，形成旋转加速冲击力，驱动自行车行驶省力，快速，效率可提高20％。

Claims (3)

1.一种偏心链轮自行车：偏心链轮、右曲柄、左曲柄、脚蹬、车架、链条、链幅调节器、飞轮、车轮、车把、车座组成。其特征：偏心链轮及其右曲柄于中轴棍连接孔位置，偏离现有自行车链轮齿顶园心，偏离现有自行车链轮中心。
2、由于偏心链轮自行车的偏心链轮旋转的不同位置，引起链条幅度的不同变化，需要装配链幅调节器。
3、偏心链轮自行车原理，完全适用于人力三轮车的驱动系统。
