Document Type and Number:
WIPO Patent Application WO/2004/087441
Kind Code:
A1
Abstract:
An automatic air supply mechanism capable of increasing the produced amount of compressed air with less number of rotations of a wheel body and producing the compressed air with a small force, comprising two compressed air producing parts formed of a first compressed air producing part (1a) and a second compressed air producing part (1b) and compressed air supply passages (2a) and (2b) for pneumatic tire supplying the compressed air produced by the compressed air producing parts to the pneumatic tire. The first compressed air producing part (1a) and the second compressed air producing part (1b) are installed on the hub drum (102a) of a hub body (102) at positions circumferentially spaced by 180°each other, and when a vehicle travels, the first compressed air producing part (1a) and the second compressed air producing part (1b) alternately produce the compressed air.
