Electric bicycle with centrally arranged motor

中置式电动自行车

Abstract

一种中置式电动自行车,包括自行车本体、用于驱动自行车的电机驱动机构以及向电机驱动机构提供电力的蓄电池和链轮传动机构;其中的电机驱动机构安装在自行车的中轴上并与链轮传动机构传动相连,蓄电池安装在自行车的鞍座下方。电机驱动机构包括电机和与电机相连的中置式同轴变速器,可实现两级减速。链轮传动机构包括链轮、滚针式双头单向轴承和脚踏传动盘,可实现电机驱动和人力驱动的简单切换。本发明的中置式电动自行车重量轻,电机中置,重心更稳定,更安全,更方便。
The invention relates to an electric bicycle with a centrally arranged motor. The bicycle comprises a bicycle body, a motor driving mechanism for driving the bicycle, a storage battery for providing electricity for the motor driving mechanism, and a chain wheel transmission mechanism, wherein the motor driving mechanism is arranged on a central shaft of the bicycle and in transmission connection with the chain wheel transmission mechanism; the storage battery is arranged below a saddle of the bicycle; the motor driving mechanism comprises a motor and a centrally arranged coaxial speed changer connected with the motor, and can realize two-stage speed reduction; and the chain wheel transmission mechanism comprises a chain wheel, a roller needle type double-end one-way bearing and a pedal transmission disc and can simply switch motor driving and manual driving. The electric bicycle with the centrally arranged motor has light weight, and the motor is centrally arranged, so that the gravity center is more stable, and the bicycle is safer and more convenient.
