Abstract

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.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an electromechanical tread braking device. Background technique [0002] The braking method of rail transit vehicles usually adopts brake shoes. The brake shoes are prone to wear during the long-term contact with the wheels. Therefore, the brake shoes need to be set in a rotatable structure to ensure that the brake shoes and the wheels are completely attached. . [0003] For example, a rail transit braking device disclosed in Chinese patent document CN111409614A includes a brake shoe assembly, a brake screw, and a brake nut. The brake nut moves linearly through the rotation of the brake screw. The moving nut is hingedly connected to the brake shoe assembly through a conversion joint; in addition, in order to ensure the fit between the brake shoe and the wheel, the brake shoe is rotatably suspended and connected through a suspension device. [0004] However, during the brak...
