Air brakes
Brake unit
The brake unit is a drum with inner shoes. The brake pads are glued onto the brake shoes.
The brake shoes are actuated by brake keys with a cam. The brake wedges are housed in brake
wedge bearings welded to the axle beam. The brake levers are attached to the brake keys and
are actuated by air brake cylinders. Due to the different braking characteristics, only one type
of brake pad may be used on an axle at a time.

Description of the brake function
14.3.1.1
Components of the braking circuit:
Brake line coupling head yellow (1) and red (2)
Relief valve (36)
Brake valve (28)
Pneumatic tension valve (29)
Balancing valve (10)
Air reservoir (31, 32)
Relay damper (30)
Quick release valve (4)
Brake cylinder (21, 22 - 34, 35)
Pneumatic spring loaded rollers (11)
14.3.1.2
Description of the operation of the brake circuit - air-suspended axle
The yellow line is used to supply the brake circuit with air, the red line as a filling line (filling the
airbox). For bleeding, the air circuit must be pressurized to at least 5 bar.
The pressure relief valve is used to relieve the system (the operation of the pressure relief valve is
described on the valve plate).
In this case, the loading valve is already preset at the factory and operates automatically. It regulates
the braking force depending on the machine load.
When there is sufficient pressure in the brake system, the blockage is released and the system is fully
functional.
