Description
本发明涉及一种 自行车、踏板车、三轮车或者类似车辆的创新踏杆驱动机构，以及使用该驱动机构的脚踏车。
市场上现有踏板车的驱动结构，有采用踏杆通过连杆连接曲柄，带动主动轮转动，如专利
ZL200610159444.5 ， ZL201080003203.6 ， ZL201020046045.X
等，结构繁琐；再有踏杆直接和曲柄轴接触，施力给曲柄，带动主动链轮转动的结构，如专利 ZL03813732.1
。但由于踏杆的支撑点设在车架的前端，这样的踏杆设置，要想使车子前行，必须增设反向轮来实现，增加了生产成本和车子的重量。
还有专利 ZL 201220259860.3
，在踏杆下部设置弧形凹状角度释放装置，实现主链盘顺时针旋转，达到车子前行目的。此结构相对简单，但由于其弧形凹状角度释放装置端点采用前低后高的结构，对其弧形凹面与曲柄轴弧面配合精度要求很高，这就给产品的加工带来了难度。在其弧形凹状角度释放装置与踏杆相连的过程中，自身与踏杆的定位，以及两个踏杆位置上的对等定位稍有偏差，就会产生曲柄轴空转、反转、卡滞、运行不畅或产生死点曲柄轴无法通过的状况。
