Abstract
Abstract 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
84 words
Vehicle suspension testing apparatus comprising a base, a vibrating platform mounted on said base, means for importing vertical vibrations to said platform, a support adapted to receive one wheel of the vehicle during the test, and which has one end mounted on said vibrating platform, and provided with means permitting relative displacement between said platform and said support, pressure detecting means interposed between said vibrating platform and the other end of said support, and said detecting means constituting means responsive to the wheel oscillations.
Claim 2
Dependent Claim
84 words
Vehicle suspension testing apparatus comprising a base, a vibrating platform mounted on said base, means for importing vertical vibrations to said platform, a support adapted to receive one wheel of the vehicle during the test, and which has one end mounted on said vibrating platform, and provided with means permitting relative displacement between said platform and said support, pressure detecting means interposed between said vibrating platform and the other end of said support, and said detecting means constituting means responsive to the wheel oscillations.
Claim 3
Dependent Claim
45 words
Vehicle suspension testing apparatus according to claim 1, in which the pressure detecting means interposed between the free end of the wheel carrier plate and the vibrating platform consist of at least one piezo-electric element connected to an electric circuit comprising an electrical measuring instrument.
Claim 4
Dependent Claim
28 words
Apparatus according to claim 1, in which the corresponding end of the wheel support is attached to said vibrating platform through the medium of a flexible connecting strip.
Claim 5
Dependent Claim
22 words
Apparatus according to claim 1, in which the corresponding end of the wheel support is pivotally mounted on to said vibrating platform.
Claim 6
Dependent Claim
33 words
Apparatus according to claim 1, in which the corresponding end of the wheel support is rigidly secured on said vibrating platform, said wheel support having a certain inherent flexibility in its longitudinal direction.
Claim 7
Dependent Claim
52 words
Apparatus according to claim 1, in which said means for imparting vertical vibrations to said platform constitutes mechanical means so arranged and located as to engage the portion of said platform which is disposed substantially in the same vertical plane as the transverse line along which the pressure detecting means are disposed.
Claim 8
Dependent Claim
32 words
Apparatus according to claim 1, including mechanical means engaging said vibrating platform, a motor, a clutch from said motor having an output shaft provided with a flywheel and driving said mechanical means.
