The invention discloses an automobile electric empennage driving device and an electric empennage thereof, the driving device comprises a motor, a driving gear and an output shaft used for driving the empennage to move, the driving gear is connected with the motor, the driving device further comprises an intermediate shaft, an intermediate gear, a driven gear and an output gear, the output gear is arranged on the output shaft, and the driven gear is arranged on the output shaft. The driven gear is movably arranged on the output shaft, the intermediate gear is arranged on the intermediate shaft, the driving gear is meshed with the driven gear, the driven gear is meshed with the intermediate gear, and the intermediate gear is meshed with the output gear. Compared with a worm gear and a worm which are made of steel or non-ferrous metal and need to be made of materials with high abrasion resistance, the gears used in the invention are made of engineering plastics, so that the material cost is reduced; transmission ratio is high and output torque is large; the device is light in weight, reasonable in arrangement, compact in structure and small in occupied space.

    本发明公开了一种汽车电动尾翼驱动装置及其电动尾翼,其驱动装置包括电机、驱动齿轮以及用于驱动尾翼运动的输出轴,所述驱动齿轮与电机相连,还包括中间轴、中间齿轮、从动齿轮以及输出齿轮,所述输出齿轮设在输出轴上,从动齿轮活动设在输出轴上,中间齿轮设在中间轴上,所述驱动齿轮与从动齿轮相啮合,从动齿轮与中间齿轮相啮合,中间齿轮与输出齿轮相啮合。对比蜗轮蜗杆所用材料为钢铁或有色金属,而且需要选择耐磨性高的材料,本专利所用齿轮均为工程塑料,材料成本降低;传动比高,输出扭矩大;重量轻,布置合理,结构紧凑,占用空间小。
