The invention relates to a transmission structure for an electric control booster with a speed reducer, and belongs to the field of automobile braking. A gear ring of the speed reducer is rotationally connected with the adapter frame through a first bearing, one end of the nut is fixedly connected with the gear ring of the speed reducer, the other end of the nut is rotationally connected with the adapter frame through a second bearing, the lead screw is rotationally connected with the nut through a steel ball, and the front end of the lead screw is fixedly connected with the limiting piece. The power assisting device has the advantages that the structure is novel, the motor is used as a power source, rotary motion of the motor is changed into linear motion through the ball screw and the planetary gear structure, so that power assisting is generated, speed reduction, torque increasing and power assisting are conducted through the planetary gears, and treading force of a driver is assisted; compared with a traditional vacuum power assisting device, the vacuum power assisting device has the advantages of being high in response speed, simple in mechanical structure, high in robustness and the like, and can be applied to conventional braking, brake-by-wire, active collision avoidance, self-adaptive cruise, intelligent driving and braking energy recovery systems.

    本发明涉及一种带减速装置的电控助力器用传动结构,属于汽车制动领域。减速装置的齿圈通过轴承一与转接架转动连接,丝母的一端与减速装置的齿圈固定连接、另一端通过轴承二与转接架转动连接,丝杆通过钢珠与丝母转动连接,丝杆的前端与限位件固定连接。优点是结构新颖,使用电机作为动力源,通过滚珠丝杠及行星齿轮结构将电机的旋转运动变为直线运动,从而产生助力,并且通过行星齿轮进行减速增扭,增加助力,对驾驶员踩踏力进行助力,与传统真空助力装置相比拥有反应速度快、机械结构简洁、鲁棒性强等特点,可应用到常规制动、线控制动,主动避撞、自适应巡航、智能驾驶以及制动能量回收系统中。
