Test stand for investigating the reliability of motor vehicle components

摘要

1. A method of testing motor vehicle equipment cooperating with an internal combustion engine on a test stand, comprising a holding device comprising a sectional girder (17) for carrying supporting elements (15, 16) for connecting to suspension devices (8, 9, 12, 13) identical with those on a vehicle being movably guided and energised by at least one controllable exciter (2, 2') for simulating movements of the vehicle, and movements of the internal combustion engine being also simulated on the motor-vehicle equipment (6, 21) by an additional exciter, characterised in that, an operative motor-vehicle drive mechanism (6) including a drivable internal combustion engine (7) is disposed in the holding device (3) in a vehicle and via suspension devices (8, 9, 11, 13) identical with those in a vehicle, and the internal combustion engine (7) serves as a separate exciter and, in order to simulate a load, is coupled to a loading machine (20) disposed in a stationary position and spatially separate from the holding device (3), the coupling being via an axle drive (14) of the motor vehicle drive mechanism (6) disposed as in a vehicle.
