The invention provides an electromechanical tread braking device, which belongs to the technical field of rail transit. The device comprises a brake shoe assembly and a linear driving assembly; the brake shoe assembly comprises a brake shoe body, a brake shoe holder and a hoisting frame, the brake shoe body is fixedly connected with the brake shoe holder, the brake shoe holder is rotatably connected with one end of the hoisting frame, and the other end of the hoisting frame is suitable for being hinged to a vehicle so that the brake shoe body can be arranged close to a wheel; and the linear driving assembly is provided with a push rod capable of linearly moving along the axis of the push rod, the push rod is rotationally connected with the brake head through a connecting piece, and the two ends of the connecting piece are rotationally connected with the brake head and the push rod through pin shafts correspondingly. According to the electromechanical tread braking device, the two ends of the connecting piece are rotationally connected with the brake head and the push rod correspondingly, so that the hoisting frame rotates through the connecting piece in the swinging process, the push rod cannot swing along with the hoisting frame when the hoisting frame swings, and the phenomenon that a driver is eccentrically clamped cannot be caused.

本发明提供一种电机械踏面制动装置，属于轨道交通技术领域，包括：闸瓦组件，包括闸瓦本体、闸瓦托和吊装架，所述闸瓦本体与闸瓦托之间固定连接，闸瓦托与吊装架的一端可转动地连接，吊装架的另一端适于铰接连接在车辆上以使闸瓦本体靠近车轮设置；直线驱动组件，具有能够沿自身轴线进行直线移动的推杆，推杆与闸瓦托通过连接件转动连接，连接件的两端分别通过销轴与闸瓦托和推杆可转动地连接。本发明提供的一种电机械踏面制动装置，通过将连接件的两端分别与闸瓦托和推杆可转动地连接，使得吊装架在摆动过程中通过连接件进行转动，因此，推杆不会在吊装架摆动时随之摆动，即不会导致驱动器出现偏心卡死的现象。
