ABSTRACT:
The geometric measurement of a vehicle is effected by apparatus comprising a casing (1) with an axle (2) protruding from the casing. The axle (2) is mounted for rotation in the casing (1) and engages with its protruding end and is fixed to a support element (3) secured to a wheel of the vehicle to be inspected. The casing (1) contains a camera block (13) for measuring the orientation of the wheel in the vertical plane, a potentiometer (12) for following the angle of the wheel, a device (11) for measuring inclinations in a vertical plane perpendicular to and in a vertical plane parallel to the wheel, connected to an electronic card (10). The camera block (13), the potentiometer (12) and the device (11) connected to an electronic card (10) emit electrical signals representative of indications correlated with the physical parameters to be detected for the geometrical inspection of a vehicle.
