Volkswagen Polo Service & Repair Manual: Vibration, Vibration Control System
| Expanded functions can be performed using Hunter RFT33VAG
Road Force Touch™ Wheel Balancer -VAS6230B4- in addition to the
previously known balancers. |
| A special characteristic of this system is testing the
radial force of wheel/tire during rolling. |
| For this purpose, a roller presses a force of approximately
635 kg (0.7 ton) against the wheel. This simulates the tire
contact force against the street surface while driving. |
| Tire contact forces fluctuate due to radial- and lateral
run-out and differing rigidity in the tires. |
| The Hunter RFT33VAG Road Force Touch™ Wheel Balancer
-VAS6230B4- detects and stores the position of the maximum
measured radial force in the tires. After that, the position of
smallest dimension between rim flange and disc wheel center is
measured. |
