A Novel Methodology of Enhancing Vehicle Safety Using a Safety Valve for Vehicle Wheels

The primary objective of this project is to use a supplementary valve for releasing the excess pressure in a tubeless wheel for commercial vehicles. The recommended cold inflation pressure for a wheel is 130–140 psi. During running conditions, the pressure increases as the temperature of the wheel increases. So, the PRV was designed in such a way that it must accept 20% of pressure rise in the tire due to heat produced during running conditions. The PRV was designed to open up at high tire pressure and to continue bleeding until it reaches a predetermined value. One of the supplementary issue which the PRV reduced is the wheel unbalance issue. The inflation valve adds up a mass in the wheel rim, which acts as an eccentric mass and requires a balance weight to solve the unbalance. Here, addition of PRV will reduce the amount of the external balance weight, since it adds up its own mass vertically opposite to the inflation valve.
