Abstract

An air pressure sensor fitting structure is provided for a vehicle wheel for fitting an air pressure sensor for detecting the air pressure of a tube of a vehicle wheel. The tube is provided with a pipe-shaped air valve and a tire covering the tube in the condition where the tube is fitted along a rim of a wheel. The air valve penetrates through the rim. A through-hole penetrating through a pipe of the air pressure valve is provided at a portion of the air pressure valve projecting from the rim. The air pressure sensor is fitted to the air pressure valve so as to cover the through-hole. The air pressure sensor can be fitted to a tubeless tire and a tubed tire while using the same structure.

Claims

1. An air pressure sensor for a vehicle wheel for detecting the air pressure of a vehicle wheel comprising:

an air valve stem;

a tire adapted to be mounted on a rim of a wheel and said air valve stem penetrating through said rim; and

a through-hole penetrating through a portion of said air valve stem that projects from said rim;

said air pressure sensor is fitted to said air valve stem for covering said through-hole and for sensing the pressure within said tire.

2. The air pressure sensor fitting structure for a vehicle wheel according to claim 1, wherein said air pressure sensor includes a housing that is secured between a rim of a wheel and a threaded portion of said air valve stem.

3. The air pressure sensor fitting structure for a vehicle wheel according to claim 2, and further including a securing means mounted on said threaded portion of said air valve stem for securing said air pressure sensor relative to said air valve stem.

4. The air pressure sensor fitting structure for a vehicle wheel according to claim 1, wherein said through hole is in communication with a semicircular groove extending around the outer surface of said air valve stem for enlarging the area of exposure of said air pressure sensor to the pressure within said tire.

5. The air pressure sensor fitting structure for a vehicle wheel according to claim 2, and further including seals mounted relative to said housing for providing a air tight seal of said housing relative to said air valve stem.

6. The air pressure sensor fitting structure for a vehicle wheel according to claim 1, wherein said air valve stem includes an air valve and said air pressure sensor is mounted in a radial direction relative to said air valve.

7. A device adapted for detecting the air pressure of a vehicle wheel comprising:

an air valve stem;

a through-hole penetrating through said air valve stem; and

an air pressure sensor mounted on said air valve stem and being in communication with said through-hole for detecting the air pressure of a vehicle wheel.

8. The air pressure sensor fitting structure for a vehicle wheel according to claim 7, wherein said air pressure sensor includes a housing that is secured to said air valve stem adjacent to a threaded portion of said air valve stem.

9. The air pressure sensor fitting structure for a vehicle wheel according to claim 8, and further including a securing means mounted on said threaded portion of said air valve stem for securing said air pressure sensor relative to said air valve stem.

10. The air pressure sensor fitting structure for a vehicle wheel according to claim 7, wherein said through hole is in communication with a semicircular groove extending around the outer surface of said air valve stem for enlarging the area of exposure of said air pressure sensor to the pressure within said tire.

11. The air pressure sensor fitting structure for a vehicle wheel according to claim 8, and further including seals mounted relative to said housing for providing a air tight seal of said housing relative to said air valve stem.

12. The air pressure sensor fitting structure for a vehicle wheel according to claim 7, wherein said air valve stem includes an air valve and said air pressure sensor is mounted in a radial direction relative to said air valve.
