  • Method of and apparatus for measuring an unbalance value of a wheel mounted on a body of an automobile
    Patent number: 4555943
    Abstract: A method of measuring an unbalance value of a wheel wherein a plurality of curves showing the relation between the magnitude of vibration of the wheel when it is rotated and the true value of the unbalance which are preliminarily obtained according to the kinds of wheel or automobile on which the wheel is mounted are memorized and compared with the magnitude of the vibration of the wheel to be tested while it is rotated. A rough value of the unbalance corresponding to the magnitude of the vibration of the wheel to be tested is obtained by using a curve M which shows the largest change of the magnitude of the vibration with respect to the true value of the unbalance. The measuring of an unbalance value is repeated with respect to the wheel on which a counter-weight corresponding to the rough value of the unbalance is attached.
