    • A vehicle wheel balancing machine having a rotating shaft which supports a vehicle wheel, a means for supporting the rotating shaft, and force sensor means adapted to detect the imbalance forces generated during the rotation of the rotating shaft; an accelerator means accelerates the shaft and the wheel and an angular sensor means senses an angular position; an electronic means processes information obtained by the force sensor means and determines the value and the position of correction masses adapted to compensate an imbalance present on the wheel; a moving indicator means is moved by a motorized actuator means and is configured to project a light dot on the wheel; a fixed indicator means projects a luminous beam, perpendicular to the axis of rotation, or a luminous dot, having a fixed and known angle of incidence on the inner surface of the wheel; a coincidence of the moving luminous point with the fixed luminous line or dot identifies a desired position of a counterweight on the diameter of the wheel.
