The invention relates to the technical field of bicycle manufacturing, in particular to a chainless manpower bicycle based on electromagnetic transmission, which comprises a support frame, a front wheel is fixedly arranged at the bottom end of the support frame, and pedals are arranged at the bottom end of the support frame. The three-phase power resistor, the three-phase surface-mounted permanent magnet generator, the three-phase permanent magnet motor and the pedals are arranged, and the three-phase rectifying circuit is connected between the generator and the motor in parallel to charge a small signal battery of the bicycle, so that the requirements of lighting, mobile phone charging, GPS, electronic display screen and other signal-level electricity utilization are met, and the situation that the current is too large during braking, and the service life of the bicycle is prolonged is prevented. The bicycle does not need a power battery and a complex motor control device, is simple in structure, low in manufacturing cost and free of maintenance, the current frequency in a circuit is in direct proportion to the pedal rotating speed of a rider, the bicycle conforms to the riding habit of a traditional bicycle, and due to the fact that mechanical decoupling is achieved between the pedal wheel and the power wheel, the bicycle type has larger design optimization space.
本发明涉及自行车制造技术领域,具体为一种基于电磁传动的无链条人力自行车,包括支撑架,所述支撑架的底端固定设置有前轮,所述支撑架的底端设置有脚蹬。本发明通过设置有三相功率电阻、三相表贴式永磁发电机、三相永磁电动机和脚蹬,发电机与电动机之间并联三相整流电路,为自行车信号小电池充电,以满足照明、手机充电、GPS、电子显示屏等信号级用电的需求,防止制动时电流过大,该自行车无需动力电池和复杂的电机控制装置,结构简单、制造成本低、免维护,电路中的电流频率与骑车人脚踏转速成正比,符合传统自行车的骑行习惯,由于脚踏轮和动力轮之间实现了机械解耦,故车型有更大的设计优化余地。
