This program is designed to improve the quality of balancing without any mental effort or loss of time by Initial unbalance SX dx operator In fact by using the normal commercially phase shift 50 available weights with pitch of 5 in every 5 g and by applying the two counterweights which a conventional wheel balancer rounds to the nearest value there could be a residual static unbalance of up to 4 g X X X The damage of such approximation is emphasized residual static g residual static 3 g Gresidual staticl g residual static 6 g by the fact that static unbalance is cause of most Niih conventional TOA of disturbances on the vehicle This new function resident in the machine automatically indicates wheel balancer the optimum entity of the weights to be applied by approximating them in an intelligent way according to their position in order to minimize residual static unbalance 5 6 When and why MATCHING The software associated with eccentricity measurement is a powerful tool for determining the need to perform relative rotation between the rim and tyre in order to reduce the eccentricity of the wheel down to acceptable limits The principle adopted is based on the consideration that a rim with acceptable tolerance mounted with an acceptable tyre can statistically generate a total eccentricity which is not acceptable but can be im
