Wheel balancer with continuous static imbalance display
An apparatus for balancing a vehicle wheel simultaneously shows both dynamic imbalance and static imbalance. At least one corrective weight is attached to the wheel to correct the static imbalance. A residual static imbalance is then determined after attachment of the corrective weight. Finally, the corrective weight is adjusted to reduce the residual static imbalance.
1. A method of balancing a vehicle wheel comprising steps of:
(a) providing an electronic wheel balancer which simultaneously shows dynamic imbalance and static imbalance of a wheel to be balanced;
(b) cycling said wheel to measure said dynamic imbalance thereof;
(c) attaching at least one corrective weight to said wheel to correct said dynamic imbalance;
(d) cycling again said wheel to measure an actual residual static imbalance after attachment of said corrective weight; and
(e) adjusting said corrective weight to reduce said actual residual static imbalance.
2. A method as set forth in claim 1 , wherein said corrective weight is adjusted in step (d) by moving said corrective weight slightly to a different position on said wheel.
3. A method as set forth in claim 1 , wherein said corrective weight is adjusted in step (d) by trimming said weight to change the corrective weight's weight amount.
4. A method as set forth in claim 1 , wherein said electronic wheel balancer shows dynamic imbalance by indicating a weight amount of said corrective weight and a position that said corrective weight should be mounted on said wheel.
5. A method as set forth in claim 4 , wherein said electronic wheel balancer indicates weight amount and placement of at least two corrective weights in a first wheel plane and a second wheel plane, respectively.
6. A method as set forth in claim 1 , wherein said electronic wheel balancer shows said dynamic imbalance in a round-off mode.
7. A method as set forth in claim 6 , wherein weight amounts of said corrective weight is rounded off to the nearest 0.25 ounce.
8. A method as set forth in claim 6 , wherein said electronic wheel balancer shows static imbalance in non-round-off mode.
9. A method as set forth in claim 2 , wherein said different position is a different angular position on a plane transverse to a rotational axis of said wheel.
