What is the purpose of the air storage tank in an air brake system?

The air storage tank in an air brake system serves the critical function of storing compressed air, which is essential for the operation of the air brakes. When the brakes are actuated, this stored air is released to the brake chambers, activating the brake mechanism and allowing the vehicle to slow down or stop effectively. The air storage tank ensures that there is a sufficient supply of compressed air readily available, thereby maintaining consistent braking performance under various conditions.

Having dedicated air storage is vital because it allows for the rapid buildup of air pressure needed for immediate braking action. Additionally, the tank helps to manage the air pressure within the system, ensuring that it remains at an optimal level for braking efficiency. By storing this compressed air, the tank plays a fundamental role in the overall functionality and reliability of an air brake system.
