OPERATION OF BRAKE COMPONENTS
2-15
2.9 LOAD SENSING VALVE, AIR SUSPENSION
Purpose
Automatic control of the braking force is
dependent on the pressure in the bellows and
therefore on the load condition of the vehicle.
Thanks to the integrated relay valve, the brake
cylinders are aerated and vented quickly.

Operation
The control valve is activated by the pressure of
the left and right bellows via connection points
41 and 42. The actuated piston (i) that moves
against the pressure of spring ‘j’ brings the
tappet (g) to a position that corresponds to the
load condition. The arithmetic average of the
bellows pressure on the left and right is the
determining factor in this.
