ABSTRACT:
An arrangement for mounting measuring devices of axle measurement equipment with a fastening plate that is adapted to be installed at the vehicle wheel aligned parallel to a flat reference surface of the vehicle axle by means of abutment pins extending through the wheel disk by way of through-openings. An incorrect alignment of the plane of the fastening plate which causes an incorrect adjustment of camber, toe-in or caster, is avoided with a completely satisfactory abutment of all abutment pins at the reference surface. Unevennesses of the reference surface or especially foreign bodies disposed between the contact surfaces of the abutment parts, such as, for example, metal shavings, will be recognized if a voltage is applied between the respective electrically conducting but mutually insulated abutment pins and the vehicle part carrying the reference surface, and if current, voltage or contact resistance is measured between the electrical connections by means of an electrical measuring device connected in the circuit.
