Device for the measuring of wheel angles of vehicles with the front wheels (1) of the vehicle placed on rollers (2) and the rear wheels (3) on roller tracks (4). Pair of scales (8) are arranged in front of and behind the vehicle essentially in level with the wheel axles and a distance over the front scales (8) also an upper pair of scales (8) are arranged. The location of and the distances between the scales are stored in a computer (9). On the front wheels (1) lasers (7) are arranged. These lasers have fastening means for the fastening on the vehicle wheels (1,3) and emit light beams (7'and 7'') in two opposite directions. The scales are connected to the computer. At measuring the front wheels are rotated on the rolls (2) or on the ground so that the two opposed laser beams (7',7'') are projected on the scales. For each scale the computer uses the point exactly between the two projection points to calculate the rotational plane of the wheel and thus the toe-in and camber angles. <IMAGE> |
