The invention discloses an electromechanical braking electric cylinder and a braking method thereof. The electric cylinder comprises a lead screw, the lead screw is rotatably sleeved with a rotor shaft, the periphery of the rotor shaft is sleeved with a rotor, and the periphery of the rotor is sleeved with a stator; a primary sun gear is arranged at the axial front end part of the rotor shaft, the primary sun gear is in transmission connection with an output shaft through a hollow planetary reducer, an internal thread matched with the screw rod is arranged in the output shaft, and the output shaft is arranged on the screw rod in a sleeving manner and is in transmission connection with the screw rod; and a pressure sensor is arranged in the hollow planetary reducer or at the front end of the screw rod. The method comprises the following steps that a motor is powered on, a rotor rotates, and the rotor drives a rotor output shaft in transmission connection with the rotor to rotate together; the rotary motion of the rotor shaft is transmitted to the primary sun gear, and is transmitted to the output shaft through the hollow planetary reducer; the output shaft rotates, and an internal thread structure in the output shaft serves as a lead screw nut to drive the lead screw to be pushed outwards.

    本发明公开了一种电机械制动电动缸及其制动方法。本电动缸包括丝杆,所述丝杆上可转动的套设有转子轴,所述转子轴的外周套设有转子,所述转子的外周套设有定子;所述转子轴的轴向前端部设有一级太阳轮,所述一级太阳轮通过中空行星减速器传动连接有输出轴,所述输出轴内部设有与丝杆匹配的内螺纹,且所述输出轴套设于丝杆上并与丝杆传动连接;所述中空行星减速器内或丝杆的前端设有压力传感器。本方法包括以下步骤:电机得电,转子旋转,转子带动与之传动连接的转子输出轴一起旋转;转子轴的旋转运动传递到一级太阳轮、经过中空行星减速器把旋转运动传递到输出轴上;输出轴旋转运动,通过内部的内螺纹结构作为丝杆螺母带动丝杆向外推出。
