Balancing machine and method for balancing vehicle wheels

A vehicle wheel balancing machine, comprising a rotating shaft which supports a vehicle wheel, a means for supporting said rotating shaft, and force sensor means adapted to detect the imbalance forces generated during the rotation of said rotating shaft;

• said machine further comprising accelerator means adapted to accelerate said shaft and said wheel and angular sensor means for sensing an angular position;
• said machine further comprising an electronic means adapted to process information obtained by said force sensor means which determines the value and the position of correction masses adapted to compensate an imbalance present on said wheel;
• said machine further comprising at least one fixed indicator means and at least one moving indicator means;
• said at least one moving indicator means being moved by a motorized actuator means and being configured to project a light dot on said wheel;
• said at least one fixed indicator means being configured to project a luminous beam or a luminous dot, said at least one fixed indicator means having a fixed and known angle of incidence on the inner surface of said wheel, wherein said moving indicator means is configured to position said light dot such that said light dot is coincident with said luminous beam or said luminous dot, the coincidence of said light dot with said luminous beam or said luminous dot identifying the diameter of said wheel, and
• wherein said moving indicator means is configured to position said light dot by means of an operator rotating said wheel according to an arc of rotation, along an internal part of said wheel, coinciding with the position of said fixed luminous dot or beam and coinciding with the desired position for an application of at least one of the correction masses.
