Further To 2A Measuring Radial Force Variations
Tension wheel on balancing machine with radial force variation measurement (vibration monitoring system).
Observe the operating instructions of the balancing machine (adjust the machine from time to time).
The contact surface of the wheel on the balancing flange (flat surface) and the centering surface must be clean.
The display disabling function must be switched off.
Adjust tyre pressure to 2.7 bar (best test pressure) when balancing and measuring radial force variations.
Particular attention must be paid to the wheel mounting when measuring radial force variations and when balancing. Using the special pressure pieces provided by the manufacturer of the balancing machine will ensure that wheels are balanced accurately and there is the highest possible repeat accuracy. Observe the operating instructions.
Maximum deviations permitted in radial/lateral force variation results:
| Panamera/Panamera S/Panamera Turbo | |
|---|---|
| Radial force variation (peak-to-peak vibrations) | 170 N |
| 1st Harmonic (variation) | 109 N |
| Lateral force variation, peak-to-peak | 90 N |
If these values are exceeded, the tyre must be matched on the rim.
If these values are not reached, the wheel must be balanced.
Information
Mount a new tyre if the radial force variation cannot be reduced to the values listed in the table.
