RTB - Radial impact test

Accident research results require wheels which retain their functionality even under the heaviest of loads. The tests serve to check and simulate the crash behavior of vehicle wheels. 

Due to different international requirements, a test facility which tests the impact resistance of the wheel must also be in a position to simulate different loads under identical testing conditions. Once the necessary or prescribed resistance value has been achieved in wheel development, the wheels are subjected to continuous in-process inspection and testing. Different material batches and alloy components make intermediate tests necessary in order to guarantee permanent sustainable manufacturing quality. The MAKRA test bench stands out on account of its simple handling and fast convertibility for a wide range of different test settings. Thanks to the built-in measuring devices, the respective test parameters and test results can be tracked and documented.

The radial impact test prevents dents of the inner rim flange if driving over small obstacles. Additionally it is used to test the wheel’s stability and resistance to breakage, for instance if driving through potholes and over larger obstacles. 

For the testing procedure, the weel will be attached onto the MAKRA test bench by an elastically mounted receiving device. The drop carriage including a linear measuring system is lifted into place by an integrated lifting spindle with servo drive. The test process is triggered by a pneumatic release mechanism. To ensure the safety of the operating staff, the fall protection must be manually unlocked before the test is initiated. After the impact and rebound of the drop carriage, it is caught by a mechanical locking blade. 

Your advantages:

  • Certified test machine manufacturer: MAKRA measuring machines are approved and certified directly in-house by well-known German vehicle manufacturers (BMW, AUDI, Daimler, Volkswagen, Porsche etc.).
  • Robust machine frame: A torsion-resistant and sturdy machine frame guarantees reliable test results.
  • Different wheel clamping systems: Only one wheel chuck is needed for all common wheel sizes and types of attachment.
  • Comprehensive area of application: Different impact angles, impact plates/wedges and drop-weight versions can easily be adjusted. All common impact and radial run-out tests to be carried out on the test bench.
  • Protective equipment: Multiple fall protection devices and safety doors garantee the safety of the operating staff.
