System to position motor vehicle wheel on horizontal measuring spindle of wheel balancing machine

摘要

The system has a lifting unit (2) engaging the wheel circumference (5). An alignment unit aligns the longitudinal central axis (4) of the wheel relative to a measurement spindle. A guide unit (20,21) moves the wheel on the spindle. At least one scanning element (6) is provided, to determine a value (t) proportional to the wheel diameter. A computer-assisted control unit (7) controls a drive (8) of the lifting unit depending on the value determined by the scanning element.
