Popularization of knowledge about brake cylinder

The function of the brake wheel cylinder is to convert the hydraulic energy input from the brake master cylinder into mechanical energy, in order to put the brake into operation. There are two types of brake wheel cylinders: single piston and double piston. The single piston brake wheel cylinder is mainly used for double lead shoe and double follower shoe brakes, and the double piston brake wheel cylinder is widely used, which can be used for both lead follower shoe brakes, bidirectional double lead shoe brakes, and bidirectional self increasing brake.
