The invention relates to an automobile generator with a variable speed ratio. A belt pulley is in transmission connection with an engine driving wheel, and the automobile generator comprises a generator shell, a rotor shaft arranged in the generator shell, a moving wheel and a planet wheel, and the moving wheel and the planet wheel are installed on the rotor shaft. The generator is characterized in that one side of the belt pulley is in transmission fit with the moving wheel through an electromagnetic control device, and the electromagnetic control device comprises an iron core formed in the generator shell and a coil wound on the periphery of the iron core; the moving wheel structurally comprises a meshing part used for being in transmission connection with the belt pulley, an adsorptionface making adsorption contact with the iron core in a power-on state of the coil, a low-speed contact face in transmission fit with the rotor shaft in the power-on state of the coil, and a high-speedcontact face in transmission fit with the planet wheel in a power-off state of the coil. The generator generates more electric quantity by increasing the rotating speed of the rotor when the engine is at a low speed, so that the power demand of the whole automobile is met. When a storage battery lacks electricity, the electric quantity of the storage battery is supplemented timely.

    本发明涉及一种可变速比的汽车发电机,通过皮带轮与发动机主动轮传动连接,包括发电机壳体、配置于发电机壳体内部的转子轴以及安装于转子轴上的运动轮和行星轮;其特征在于,所述皮带轮的一侧经由电磁控制装置与运动轮传动配合,所述电磁控制装置包括成型于发电机壳体内部的铁芯以及绕制于铁芯外周的线圈;所述运动轮的结构包括:用以与皮带轮传动连接的啮合部、在线圈通电状态下与铁芯吸附接触的吸附面、在线圈通电状态下与转子轴传动配合的低速接触面,以及在线圈断电状态下与行星轮传动配合的高速接触面。本发明使发电机在发动机低速时通过提高转子转速发出更多电量,满足整车用电需求。在蓄电池亏电时及时补充蓄电池电量。
