Patent ID: 7610808

Claim:
A method for balancing motor vehicle wheels, comprising following operations: mounting a wheel onto a rotating spindle of a balancing machine; using a probe of known type for selecting balancing planes and diameters, and providing data relating to the planes and diameters to the balancing machine; spinning the wheel; calculating a value of imbalance W; calculating an entity and angular position for balancing weights to be applied in the balancing planes and diameters previously selected by an operator; characterised in that said method comprises following further activities; a. during the spinning of the wheel, measuring an acceleration time T ACC between two predetermined speeds of the wheel; b. calculating an imbalance threshold value W B with the equation as follows: W B =K S ×T ACC +S 0 where K S is a threshold constant expressed in grams per millisecond (g/ms) S 0 is a minimum threshold value expressed in grams (g) T ACC is an acceleration time expressed in milliseconds (ms) c. applying a balancing weight only if said imbalance value is above the calculated threshold value.
