Abstract

The application provides a parking brake cylinder, which includes a parking cylinder body, an intermediate body, a brake cylinder body, a relief device and a force transmission device. There is a parking piston on the outside of the platform, and the parking piston and the parking cylinder form a parking cylinder chamber; the brake screw is connected to the brake piston, and the brake piston and the brake cylinder form a brake cylinder chamber; the parking piston passes through the parking nut, parking The leading screw is connected with the relief device, and the parking piston is connected with the brake piston through the force transmission device. The parking brake cylinder controls the force transmission between the parking lead screw and the brake piston through the relief device and the force transmission device, thereby controlling the application of the parking braking force.

Description

technical field [0001] The application belongs to the technical field of rail vehicle braking, and in particular relates to a parking brake cylinder and a brake caliper unit. Background technique [0002] The spring storage type parking cylinder is used to provide long-term parking braking force for the vehicle, and it usually needs to be used in conjunction with the brake cylinder that provides the vehicle's driving braking force. The working principle of the parking cylinder is: filling the parking cylinder cavity with pressure medium to release the parking brake, and discharging the pressure medium to apply the parking brake by compressing the spring force. [0003] The invention patent with publication number CN103318157A discloses a parking brake mechanism for rail vehicles, including a cylinder body, a cylinder head, a piston, a screw rod, and a compression spring. A rotatable ratchet cylinder with a one-way ratchet on the top is arranged inside the cylinder head. The...
