Steps in the Air Brake System Development

As a general rule, the development, design and test assembly of a new pneumatic brake system is done directly through prototyping. The following steps illustrate the development process:

  • Measurement of the existing hydraulic brake pressures at the vehicle.
  • Selection of the WABCO brake device based on the pressure data measured earlier at the vehicle.
  • Determination of the optimal component placement.
  • We use state of the art technology to achieve maximal precision in the development and construction, such as the FAROArm® Fusion laser scan arm.
  • Construction and manufacturing of special parts and components.
  • Complete test assembly to realistically determine whether a retro-fit system for a particular pneumatic brake system is feasible.
  • Tests to determine whether the entire pneumatic brake system works properly and is sealed off.
  • Practical brake measurements using the VZM300 decelerometer followed by the analysis of the hydraulic and pneumatic pressure data as well as the brake deceleration.
  • Various measurements according to WABCO standards (the WABCO Standard GmbH is the German business unit of American Standard Inc.), such as fill time measurements, testing for leaks, etc.
  • The final step in the development of the pneumatic brake system is obtaining the DEKRA or TÜV approval certificate (DEKRA, German Motor Vehicle Inspection Authority / TÜV, German Technical Inspection Authority).
