Abstract

PURPOSE:To absorb shock on a tire by making air go and return between an air chamber and a tire chamber by adding an air chamber in neighboring to a disc part and a rim part of a wheel, and communicating this air chamber into the tire chamber via a connecting hole. CONSTITUTION:An air chamber 3 is added in neighboring to a disc part 1 and a rim part 2 of a wheel respectively. And this air chamber 3 is made to communicate to a tire chamber formed with the rim part 2 and a tire 6 via a connecting hole 4. According to the constitution, when shock from a road face is acted to the tire 6 under running of a vehicle, air in the tire chamber is run out into the air chamber 3 via the connecting hole 4. While, when the shock is gone, air in the air chamber 3 is returned into the tire chamber again. As air flows in contracted with the connecting hole 4 in this occasion, energy of shock can be absorbed hereby. Therefore, riding comfort in a vehicle can be improved.

Wet performance, load performance, wear resistance performance, puncture resistance performance,
Various performances such as ride comfort and noise level are often contradictory to each other, and improving one often results in a decrease in the other. In particular, with flat tires that have become popular in recent years, ride comfort is often sacrificed in order to improve other performance. On the other hand, no particular performance improvements have been made to the wheels that pair with the tires, other than making them lighter and reducing the unsprung weight.

The air flows into the air chamber in contact with the rim, and when the impact passes and the air pressure inside the tire returns to its original level, the air passes through the final stage and returns to the inside of the tire. However, since the air passes through small communication holes during leverage, the energy of the impact is consumed and absorbed here.

However, since the air passes through the small communication hole (4) during leverage, the energy of the impact is consumed and absorbed here, improving the ride comfort of the vehicle. The valve (7) is installed between adjacent bolt holes so as not to interfere with the wheel mounting bolts.
