<p>This apparatus for testing the suspension system of vehicles comprises a platform to which vertical vibrations are imparted possibly through a crank-and-rod mechanism driven from a motor having a flywheel and a clutch mounted on its output shaft, said platform supporting the wheel to be tested through a shaped plate pivoted at one end to said platform and bearing at the opposite end on one or a plurality of pressure detecting elements such as piezo-electric elements responsive to the stress variations caused by the wheel oscillations and to transmit same to a dial instrument and/or a recorder.</p> |
