Latest Patents

Hofelt's latest patents include a method and apparatus for reducing tangential force variation in pneumatic tires. This innovative method involves mounting the tire on a wheel rim, inflating it to operating pressure, and rotating it under a predetermined load against a loading drum. Force transducers measure the tangential force variation as the tire rotates. The data collected is processed by a computer to determine the magnitude of the variation and the phase angle. The computer then outputs a V-shaped ramp voltage level signal to control a servo-valve, which moves a rotary grinder into contact with the inner tread ribs of the tire. This grinding process is repeated based on the magnitude of the variation, ensuring optimal tire performance.
