Volkswagen Polo Service & Repair Manual: Vibration, Vibration Control System

Volkswagen Polo Service & Repair Manual / Whels, Tires, Whel Alignment / Handling Problems / Vibration / 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.
