Abstract:
A method for determining values for balancing a vehicle wheel, the method comprising:mounting the vehicle wheel with its horizontal axis on a shaft of a balancing machine such that an unbalance-measuring procedure and a balancing operation can be carried out; sensing locations on the vehicle wheel using a light beam emitted by a light source and reflected to a position-sensitive receiver, wherein the light source and the position-sensitive receiver are pivoted synchronously about a common axis in a measurement plane and directions of the emitted light beam and the reflected light beam are moved within the measurement plane, wherein the measurement plane extends below said shaft and intersects an inner rim surface of the vehicle wheel at an approximately right angle or an obtuse angle; measuring the spacings of the sensed locations relative to a stationary reference location of the balancing machine during successive measuring steps, wherein measuring is from the reactions of the emitted beam and the reflected beam; and evaluating the values for balancing the vehicle wheel from the measured values of said spacings and the measured values ascertained by the unbalance-measuring procedure.
