Abstract
A method of correcting unbalance on a motor vehicle wheel by means of at least one balancing weight which can be fixed to the wheel at appropriate positions ascertained by an electronic measuring apparatus during an unbalance measuring procedure involves the use of a sensing device which is coupled to the electronic measuring apparatus and which senses relevant dimensions of the wheel for storage thereof in the electronic measurement apparatus, for evaluation of the measurement values obtained in the unbalance measuring procedure.
Claims14
A method of correcting unbalance on a motor vehicle wheel by means of at least one balancing weight securable to a portion of the wheel in an unbalance correcting position thereon, including the steps of:
- performing an unbalance measuring procedure using an electronic measuring means for ascertaining the unbalance correcting position at which the at least one balancing weight is to be secured to the wheel, and
- performing an unbalance correcting procedure by arranging the at least one balancing weight at the unbalance correcting position on the wheel, whereby a sensing means is used, which is coupled to the electronic measuring means and which senses at least one wheel dimension for storage thereof in the electronic measuring means, for comparative evaluation of measurement values obtained in the unbalance measuring procedure to ensure that the at least one balancing weight is positioned at the unbalanced correcting position during the unbalanced correcting procedure.
A system for correcting unbalance of a wheel by use of balancing weight to be fixed at a balancing position on the wheel comprising:
- sensing means for sensing a wheel portion at which at least one balancing weight is to be fixed to the wheel;
- position detecting means co-operable with said sensing means for detecting and generating data corresponding to at least one position at which said at least one balancing weight is to be fixed to the wheel;
- storage means connected to the position detecting means for storing such position data;
- comparison means operatively connected to said storage means and to said position detecting means for comparing the stored position data with a current position data of said at least one balancing weight;
- and
- means connected to the output of said comparison means for signalling when the stored position data corresponds with the current position data.
