Function of the brake guide pin
The role of the car brake guide pin is to allow the brake pads to act vertically on the brake disc, as for the rubber sleeve is to protect the guide pin from being exposed, if it is exposed, it is easy to see the water rust and corrosion, falling on the dust and gravel caused by wear and tear.
The brake guide pin rubber ring serves to protect the brake guide pin from being exposed. If it is exposed, it is susceptible to water and rust, dust and gravel, which can cause wear and tear.
The role of the guide pin of the brake cylinder: let the brake pads act vertically on the brake disc, as for the rubber sleeve is to protect the guide pin is not exposed to the outside, if it is exposed to the outside it is easy to see the water rust and corrosion, falling on the dust and gravel, resulting in wear and tear.
1. Brake splitter pump guide pin rubber sleeve can not be installed.
2. not installed may be rattling, no rubber sleeve dust sand will enter the piston pin inside the conduit caused by friction, resulting in rattling.
Car brakes are divided into air brakes and liquid-oil brakes: air brakes are made of air compressor (commonly known as air pump), at least two cylinders, a brake master cylinder, the front wheel of a quick release valve, the rear wheel of a relay valve. Brake sub-pumps four, adjusting back four, cam four, brake shoes eight and brake ancient four composition.
Although there are many types of vehicles, the construction is more or less the same. This should be said to be the credit of standardisation, but also the need for large-scale production lines. With the development of society, scientific and technological progress and changes in demand, the appearance of railway vehicles began to change, especially the passenger carriages are no longer the same old face. But their basic structure has not changed significantly, only the specific components have a more scientific and advanced structural design.
Generally speaking, the basic structure of the vehicle by the body, the car underframe, walking part, the hook buffer device and braking device composed of five major parts.
Vehicle body is the vehicle for loading goods or passengers on the part, but also the installation and connection of other components of the vehicle base. Early vehicle body is mainly wood structure, supplemented by steel plates, bow bars, etc. to strengthen. Modern vehicle body to steel or light metal structure.
