Hunter RFT33VAG Road Force Touch™ Wheel Balancer:VAS6230B4
Expanded functions can be performed using :VAS6230 B4 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 against the wheel. This simulates the tire contact force against the road surface while driving.
Tire contact forces fluctuate due to radial and lateral run-out and differing stiffness in the tires.
The :VAS6230 B4 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.
