Abstract
A vehicle wheel balancing method includes determining, by using an electronic computing device, the position of the application plane and the angular position of each weight within a range about prechosen balancing planes, computed on the basis of weight values chosen by the operator from a finite number of values available in practice. A wheel balancing apparatus includes a rotary shaft on which a vehicle wheel is mounted, and the electronic computing device discussed above.
Claims9
A method for balancing vehicle wheels by means of at least one balance weight to be applied to the wheel rim, comprising the steps of:
- determining and memorizing the position of a prechosen balancing plane and a balancing plane weight value;
- determining an application plane weight value;
- and
- determining, by electronic computing means, the position of an application plane and an angular position for application of each balance weight weighting an amount equal to said application plane weight value within a relatively small range about the prechosen balancing plane computed on the basis of the application plane weight value.
An apparatus for balancing a vehicle wheel by applying at least one balance weight, comprising:
- a rotary shaft mounted on a base;
- means for clamping the wheel onto said rotary shaft;
- means for measuring centrifugal forces of said rotary shaft in at least two reference planes;
- means for computing unbalance of the wheel;
- and
- means for computing a balancing plane weight value for a balance weight to be applied in a predetermined balancing plane of the wheel at a first angular position computed by the computing means,
- wherein the computing means comprises a memory for storing unbalance data, processor means for computing an application plane and a second angular position of an application plane balance weight chosen by the operator from a finite number of values available in practice, and a position transducer operably connected with said processor means and arranged to indicate said application plane and said second angular position.
