ABSTRACT:
Measuring system for the measuring of wheel angles comprising cameras (21) pivotable on rear wheel (22) fastenings and looking both on front wheel marker arrangements (24) and a marker device (25) arranged perpendicular relative the length direction of the vehicle. The camera registers the angles of the wheel it is mounted on by viewing the marker device and the angles of the front wheel by subtracting the angles of the wheel with the camera from those obtained for the marker arrangement on the front wheel. The marker arrangement is diametrically symmetric and allows together with pivotability of the camera a rotating of the wheels over a half revolution so that possible mounting errors can be detected and correlated for.
