Title: Tire wheel
Inventor: TOMIZAWA SHINICHI
IPC: B60B19/06
Filed: 1983-02-25
Abstract: PURPOSE:To automatically control spring constant of a tire according to a condition of a road surface by providing, on the inner peripheral face of a rim, a surge tank part with said rim as a partition and putting in communication a pressure space in the tire with the surge tank part through a throttle valve. CONSTITUTION:A surge tank part 5 formed in the inner peripheral face of a rim 3, with said rim 3 as a partition, is put in communication with a pressure space in a tire 4 through a throttle valve 6. Accordingly, at the time of traveling on the smooth road surface, air pressure in the tire 4 does not move into the surge tank part 5 due to the throttle valve 6 and a required spring contant is maintained. At the time of traveling on an uneven road surface, since the air in the tire 4 is compressed by the external pressure from the road surface, it passes through he throttle valve 6 to move into the surge tank part 5, and the spring constant is lowered, then the vibration is effectively absorbed.
