Brake Inertia Dynamometer
Description
Flywheel brake test rig with climate chamber and wheel load simulation unit
Test objects:
- Disc brakes
- Drum brakes
- Quarter, half and complete axle systems incl. complete wheel
- Friction materials, friction linings
- calipers
Testing options:
- Standard test programs according to SAE J2522, AK Master, AMS-Fade etc.
- NVH behavior according to SAE J2521
- Limit load and cracking behavior of brake discs and brake components
- Wet and fog testing
- Residual grinding torque determination and parking brake testing
- Dynamic wheel load distribution
- Cornering (high lateral forces - Hockenheimring or Nürburgring)
- Vibration and surface condition of the road (slab joints, track crossing, cobblestones) and roughness of the road surface
- Special events such as deep potholes, high road shoulder
Test specimen adaptations (examples):
- Performance Standard
- Performance steering knuckle assembly
- NVH with suspension strut
- NVH with quarter axle and complete wheel
- NVH with complete axle
Measuring systems:
