According to the E-bike two-gear electric drive assisting method, a motor, a planet wheel system and a shell are arranged in an electric drive assembly, the two ends of the planet wheel system are fixedly connected to a frame, the two ends of a spoke of a rear wheel are connected with the shell and a rim respectively, and a motor control unit is connected with the motor through a wire; a gear shifting button is arranged at a handle of the E-bike, the gear shifting button is connected with a motor control unit through a wire, a motor is started to rotate by manually switching the gear shifting button, or a torque sensor is arranged in an electric drive assembly to automatically monitor the torque value of a shell, and a threshold value is set in the torque sensor; the torque sensor is connected with the motor control unit through a wire, so that the planet wheel system, the shell and the rear wheel are sequentially driven by the motor to rotate, and manpower is saved. A power-assisted electric drive device and a manual or automatic gear shifting device are installed on the bicycle, a motor drives a planet wheel system and a reverse shell belt rear wheel to rotate, two-gear speed change is achieved through forward and reverse rotation of the motor, and the bicycle can be used in traveling, mountaineering and other occasions.
一种E‑bike的两档电驱助力方法,在电驱总成中设置电机、行星轮系统和壳体,行星轮系统的两端固定连接在车架上,后轮的辐条的两端分别与壳体和轮圈连接,电机控制单元通过导线与电机连接;在E‑bike的把手处设置换档按钮,换档按钮通过导线与电机控制单元连接,通过手动切换换档按钮来启动电机转动,或在电驱总成中设置扭矩传感器来自动监测壳体的扭矩值,并在扭矩传感器中设置阈值,将扭矩传感器与电机控制单元导线连接,从而用电机依次带动行星轮系统、壳体和后轮转动,节省人力。通过在自行车上安装助力的电驱装置、手动或自动调档装置,用电机驱动行星轮系统和反壳带后轮转动,电机正反转实现两档变速,可以兼顾旅行和登山等使用场合。
