Unit brake definition

A combined braking component in which a brake cylinder acts on only one brake shoe (or a pair of brake pads, or a brake beam component) through some transmission components. The tread brake unit consists of a brake cylinder, a lever installed in the box, a set of automatic brake shoe clearance adjusters, as well as brake shoes, brake shoe holders, brake shoe holders, etc. In this way, the basic braking device of a car will become composed of many sets of braking units

Due to the short-term operation of the braking unit, which means that the power on time is very short, the temperature rise of the braking unit cannot reach a stable temperature rise during the power on time; The intermittent time after each power on is longer, during which the temperature is enough to drop to the same level as the ambient temperature. Therefore, the rated power of the braking resistor will be greatly reduced, and the price will also decrease accordingly; In addition, due to the fact that I only has one, with a braking time of ms level, there is a low requirement for the transient performance indicators of power tube opening and closing, and even a requirement for the shutdown time to be as short as possible to reduce the shutdown pulse voltage and protect the power tube; The control mechanism is also relatively simple and easy to implement. Due to the above advantages, it is widely used in potential loads such as cranes and in situations where quick braking is required but short-term working conditions are required.
