The invention discloses an automobile steering wheel linear driving device, which comprises a motor body, a reduction gear box, a left-handed screw rod and a right-handed screw rod, and is characterized in that the reduction gear box consists of an upper end cover assembly, a lower end cover assembly, a planetary reduction mechanism and a parallel shaft reduction mechanism; wherein the planetary reducing mechanism comprises a sun gear, an inner gear ring, a planet gear, a planet shaft, a planet carrier and an output shaft, the parallel shaft reducing mechanism comprises a center gear, an idle gear, a left-handed rotation output gear and a right-handed rotation output gear, the sun gear is driven when the motor rotates forwards and backwards, and then the planet carrier and the output shaft are driven through the planet gear to serve as power output for reducing speed and increasing torque. When the output shaft rotates positively and negatively, power is transmitted to the center wheel connected with the output shaft, and the center wheel further transmits the power to the left-handed output wheel and the right-handed output wheel through the idle wheel. The mechanism is compact and small in structure, small in occupied space, high in efficiency and low in cost, and horizontal movement of an object connected with the left lead screw and the right lead screw can be controlled through one motor.

    本发明公开了一种汽车方向盘线性驱动装置,包括电机本体,减速齿轮箱、左旋丝杆和右旋丝杆,所述减速齿轮箱由上端盖组件、下端盖组件、行星减速机构、平行轴减速机构组成,其中行星减速机构包括太阳轮、内齿圈、行星轮、行星轴、行星架和输出轴,平行轴减速机构包括中心轮、惰轮、左旋输出轮和右旋输出轮,当电机正反转时驱动太阳轮,再通过行星轮带动行星架和输出轴作为减速增扭的动力输出,输出轴正反转动时会将动力传递到与之连接的中心轮,中心轮进一步将动力通过惰轮传递到左旋输出轮和右旋输出轮。本发明结构紧凑、小巧、占用空间小,效率高,成本低廉,并且通过一个电机即可控制与两个左右丝杆相连物体的水平移动。
