Device for testing the effectiveness of vehicle shock absorbers has a drive mechanism for setting the wheel in vibration in conjunction with an elastic element, the rigidity of which can be set according to test vehicle weight

摘要

Device comprises a wheel support surface with a drive mechanism that sets the axle mass in perpendicular resonant vibration. The amplitude of the resonance vibrations is measured and displayed. A spring or elastic member is placed between the wheel support and its drive mechanism with the spring rigidity matched to the wheel loading of the vehicle under test.
