Principle of semi-trailer braking system

Answer:

There is a hand brake commonly known as air break semi-trailer and large trucks are used as air break off gas automatic brakeThe first principle is as follows, pump air break or truck brake pump structure of pump and non air break is not the same as the air break with a large spring pressure big, when you release the air break when driving at this time is divided into a pressure pump. A big spring force the car to compression. Stop the handbrake pull up to stop the transmission of pressure pump, no gas spring automatically bounced up the brake lever up so as to realize the braking effectI wonder if you can read it or make it too tired.

The engine drives the air pump to generate air pressure, and the air pump is sent to the air storage tank by air pressure and is pressurized. The air storage tank and the brake master pump are connected at any time to supply the air pressure to the brake master pump. Air pressure through the brake master pump in the transmission to the brake pump, the brake pump is sealed in the state, air pressure after entering a physical effect to promote the brake lever to achieve the brake.There is a hand brake commonly known as air break semi-trailer and large trucks are used as air break off gas automatic brakeThe first principle is as follows, pump air break or truck brake pump structure of pump and non air break is not the same as the air break with a large spring pressure big, when you release the air break when driving at this time is divided into a pressure pump.
