SYSTEM FOR CHECKING THE ATTITUDE ANGLES OF THE WHEELS OF A LAND VEHICLE, IN PARTICULAR FOR A CONTACTLESS CHECK, AND ASSOCIATED METHOD OF CHECKING

A system for checking the attitude angles of wheels is provided, in a manner that is known per se, with a vertical measuring or column 1 on which some transmitters and receivers of electromagnetic signals are installed-for example coherent light illuminators (typically lasers) and associated reflected light sensor-which overall define a group of distance sensors.According to the disclosure, the proposed system is produced using distance sensors appropriately fitted on a single vertical measuring structure which is positioned, on a side of a movement path, where the vehicle equipped with wheels moves, that has a substantially transverse direction with respect to the acquisition direction of the distance sensors.
