    • This invention has its purpose to present a regenerative brake device to increase its regenerative brake power at the time of high-speed driving, without impairing driving comfort. A regenerative brake device according to the present invention comprises a driving wheel linked with a rotary shaft of an electric motor through a power transmission system and a battery charging circuit provided between said electric motor and a set of batteries to switch on and off and execute its regenerative braking in correspondence to the duty factor of control pulse signals input from the battery charging circuit and characterized in that the duty factor of control pulse signals input to said battery charging circuit decreases in correspondence to increases in the rotation rate of the rotary shaft of said electric motor to cause braking not exceeding a predetermined level as the rotation of said shaft increases.
    • 本发明的目的是提供一种再生制动装置,以在高速行驶时增加其再生制动功率,而不损害驾驶舒适性。 根据本发明的再生制动装置包括通过动力传递系统与电动机的旋转轴连接的驱动轮和设置在所述电动机和一组电池之间的电池充电电路,以接通和断开并执行其 对应于从电池充电电路输入的控制脉冲信号的占空因数的再生制动,其特征在于输入到所述电池充电电路的控制脉冲信号的占空因数与所述电池充电电路的旋转轴的转速的增加相对应地减小 电动马达随着所述轴的旋转增加而使制动不超过预定水平。
