Abstract
Based upon rigidity classifications of wheels and radial runout classifications of the wheels, the lower the rigidity classification or the lower the radial runout classification, the more likely a methodology (heavy point-light point alignment) is selected in which a light point of static imbalance of the tire and a heavy point of static imbalance of the wheel are aligned with each other, than another methodology (radial force variation alignment) in which a peak position of a primary component of radial force variation of the tire and a bottom position of a primary component of radial runout of the wheel are aligned with each other, so as to assemble a tire and a wheel together.
Claims20
An apparatus for assembling a tire and a wheel, comprising:
- a first input unit configured to receive rigidity information of the wheel on which the tire is to be mounted;
- a second input unit configured to receive an amount of radial runout of the wheel on which the tire is to be mounted;
- a selection unit including a table stored in advance, wherein the table comprises classifications which include a plurality of rigidity classifications for classifying the wheel by rigidity based upon the rigidity information and a plurality of radial runout classifications for classifying the wheel by the amount of radial runout, each of the classifications being associated with one of tire/wheel assembling methodologies which include a first methodology and a second methodology, the first methodology being a methodology in which a light point of static imbalance of the tire and a heavy point of static imbalance of the wheel are aligned with each other, the second methodology being a methodology in which a peak position of a primary component of radial force variation of the tire and a bottom position of a primary component of radial runout of the wheel are aligned with each other, wherein the selection unit is configured to select a tire/wheel assembling methodology retrieved from the table based upon the rigidity information of the wheel received by the first input unit and the amount of radial runout of the wheel received by the second input unit;
- and
- an output unit configured to output the assembling methodology selected by the selection unit,
- wherein the tire and the wheel are assembled together in accordance with the output assembling methodology.
