GIANT 9000 Series

Brake Test Systems

The major test target is to detect noise and vibrations generated by the vehicles brake. Our intention was to build a dynamometer that can operate either with brakes mounted to the complete vehicle, or with just the axle module mounted to a universal adaptor system or wheel suspensions.

By means of this dynamometer, the brakes can be exposed to either stop brakings or endurance brakings according to standardized NVH test matrix.

Applications

Technical examinations of noise and vibration (NVH) on brakes, installed in complete passenger cars and light commercial vehicles
Realistic processing of NVH problems in the brakes in connection with the complete vehicle
Examination of noise and judder
Examination of creep and groan in vehicles with automatic transmission
Testing of damping measures such as noise shims or coating of the friction linings
Testing of complete brake units for passenger cars
Testing of drum and disk brakes of any type and size

Technical Data (based on vehicle axle, not on dyno axle)
