The invention relates to a two-way push type electronic mechanical braking device of a pilotless automobile. The electronic mechanical braking device is composed of a motor, a movable shell top, a connecting rod mechanism, a worm gear, a worm, a gear A, a gear B, a brake disc, a brake block, a ratchet bar device, an automobile electronic control unit, a displacement sensor and the like. The movable shell top comprises a matched guide rail, a guide pin and a displacement sensor. The matched guide rail and the guide pin are used for limiting relative movement of the movable shell top and the brake caliper. After the torque output by the motor is subjected to speed reduction and distance increase through the worm gear and the worm, the rotating motion of the gear B around the shaft is converted into the rotating motion of the connecting rod, the brake caliper does linear motion, meanwhile, the movable shell top does linear motion in the direction opposite to the brake caliper, the brake blocks located on the two sides of the brake disc press the brake disc, and therefore braking is achieved. The device is rapid in braking response, large in braking force, simple in overall structure and easy to install, and the parking function can be achieved through the ratchet bar device in the device.
本发明公开涉及了一种无人驾驶汽车双向推进式电子机械制动装置,该电子机械制动装置由电机、移动壳顶、连杆机构、蜗轮、蜗杆、齿轮A、齿轮B、制动盘、制动块、棘齿条装置、汽车电子控制单元、位移传感器等装置组成。所述移动壳顶包括配合导轨、导向销、位移传感器,配合导轨与导向销用于限制移动壳顶与制动钳的相对运动;所述电机输出的力矩经过蜗轮、蜗杆减速增距后,齿轮B绕轴的旋转运动转化为连杆的旋转运动,制动钳直线运动的同时移动壳顶向着与制动钳相反的方向进行直线运动,使位于制动盘两侧的制动块压向制动盘,从而实现制动。该装置制动响应迅速,制动力大,整体结构简单,易于安装,且内部的棘齿条装置可以实现驻车功能。
