DYNAMIC TEST FIXTURE FOR A MOTOR VEHICLE, TEST STAND AND PRODUCTION LINE WITH A DYNAMIC TEST FIXTURE AND PREFERRED USES OF SAME FOR TESTING A STABILIZING SYSTEM OF A MOTOR VEHICLE

摘要

A dynamic test fixture has a support frame ( 3 ) whose dimensions ( 31 ) in the direction of a transverse axis (y) are smaller than a distance between the wheels of a vehicle ( 8 ). Via a first unit ( 71 a, 71 b, 71 c) of a controllable adjusting device ( 7 ), the support frame ( 3 ) is displaced approximately vertically underneath the vehicle ( 8 ) so that the vehicle ( 8 ) is moved into a raised testing position. A second unit of the controllable adjusting device ( 7 ) acts on the support frame ( 3 ) in such a way that the vehicle ( 8 ) is moved into at least one position (Nx, Ny) that deviates from the horizontal position. A third unit ( 73 ) influences the support frame ( 3 ) in such a way that the vehicle ( 8 ), which it is situated in the raised testing position, is briefly rotated about a vertical axis (z). The test fixture is advantageously used to test a stabilizing system (ESP device) of the vehicle ( 8 ).
