Air assist system, also known as vacuum brake assist system and vacuum servo brake system, is a type of brake booster used to assist braking. The vacuum power assist system is a braking system that adds a set of power assist devices provided by other energy sources on the basis of manual hydraulic braking, so that both human and engine power can be used as braking energy sources.
The following is a specific introduction to the vacuum assist system:
1. Principle: The working principle of the vacuum power assist system is to use the air sucked in by the engine during operation, causing one side of the booster to become vacuum. The pressure difference relative to the normal air pressure on the other side is used to strengthen the braking thrust.
2. Meaning: The vacuum assist system is a larger diameter chamber with a diaphragm (or piston) in the middle that is equipped with a push rod, separating the chamber into two parts. One part is connected to the atmosphere, and the other part is connected to the engine intake pipe through a pipeline.
