The invention relates to a gear reverser for a bicycle or an electric moped. The gear reverser is provided with a long output transmission shaft and a short output transmission shaft, and four bevel gears with mutual teeth are arranged in the gear reverser, so that the rotating speeds of the long shaft and the short shaft are always the same and the rotating directions are always opposite when the long shaft and the short shaft are in transmission; the gear reverser is installed on one side of a bicycle driving wheel hub, the long shaft penetrates to the other side through the hub, the long shaft and the short shaft are distributed on the two sides of the hub, and therefore various applications such as chainless direct driving and rope driving of a bicycle are achieved.
本发明是一种用于自行车或电动助力车的齿轮换向器,它拥有一长一短两个输出传动轴,齿轮换向器内部含有四个相互齿的伞形齿轮,使得长轴和短轴传动时转动速度始终相同,转动方向始终相反;将齿轮换向器安装到自行车驱动轮花鼓的一侧,长轴通过花鼓穿到另一侧,让长轴和短轴分布在花鼓两侧,从而实现自行车的无链直接驱动和绳驱动等多种应用。
