BRAKE CHAMBER WITH SPRING BRAKE (ENERGY ACCUMULATOR). A brake chamber with spring brake (energy accumulator) is designed for use in the pneumatic braking systems of trucks, buses and commercial vehicles. It converts compressed air pressure into mechanical force that is applied to the wheel braking mechanism. The spring brake section ensures the operation of the parking and emergency brake, providing the force required to hold the vehicle stationary even when air pressure is lost. The chamber is engineered for heavy‑duty operation and features a robust housing, powerful spring mechanism and sealed diaphragms resistant to wear and temperature changes. The catalog includes brake chambers and spring brake units in various sizes and configurations for different truck and trailer models. Selection is based on the braking system type and vehicle specifications.
