Service chambers must be absolutely reliable under all conditions for safe truck operation. But not even the toughest road on earth can match the extreme conditions we put our
Service Chambers through in our laboratory. This gives us confidence that at any time or place, they will function correctly.
Purpose:
The Haldex Service Chamber is mounted at the brake assembly and converts air pressure from a quick release valve or a relay valve into a mechanical force to apply the foundation brakes. A variety of sizes are provided to match the braking requirements of different capacity axles.
Operation:
Application – application from the control valve is admitted into the inlet port on the pressure housing behind the diaphragm. When the pressure overcomes the force of the relatively lightly loaded return spring, the diaphragm flexes forward, moving the internal plate and push rod, applying a force to the brake mechanism.
Release - when the control valve is returned to the release position, the air pressure is removed from the brake chamber, allowing the brake mechanism to return to the initial release position.
