Brake cylinder
The brake cylinder is a part of the compressed air brake or the hydraulic brake in which the technical medium of the braking force transmission ( compressed air or brake fluid ) translates its force into the movement and exertion of force by the brake rod . There are different types of brake cylinders depending on the application. As a rule, there is a master brake cylinder (HBZ) through which pressure is exerted on the pneumatics or hydraulics. Still exist, e.g. B. in drum brakes , so-called wheel brake cylinders (RBZ), which transmit the pressure built up by the master cylinder in the brake system to the brake shoes .
The cylinder-shaped wheel brake cylinders with internal pistons are permanently mounted on the brake anchor plate in the hydraulic brake and act on the brake shoes. The brake cylinders of disc brakes are located in the brake caliper and press on the brake pads . The brake cylinders of the compressed air brake are usually attached to the chassis and actuate the brake cams via a linkage, which spread the brake shoes.
