Abstract

A vehicle wheel sensor assembly (22) includes a pressure sensor (24) and a counterweight (26) mounted to a band (28). The band (28) is of a length to extend around the inner diameter of the wheel rim (12) such that the pressure sensor (24) is mounted 180 degrees opposite the counterweight (26) when installed around the inner diameter. The sensor (24) and the counterweight (26) thereby minimally effects the balance of the vehicle wheel assembly (10). The band (28) includes a male end (32) which fits into a female end (34) in a zip-tie like manner. An antenna (36) is mounted along the length of the band (28) for a length approximately equal to the rim (12) inner diameter such that heretofore transmission/reception problems are essentially eliminated.

Claims

1. A vehicle tire sensor assembly comprising:

a band having a length to extend about an inner diameter of a vehicle wheel rim;

a sensor mounted along said band;

a counterweight mounted along said band away from said sensor, wherein said counterweight comprises a power source that powers said sensor

2. The vehicle tire sensor assembly as recited in claim 1, wherein said sensor and said counterweight are mounted along said band to locate said sensor 180 degrees opposite said counterweight about said inner diameter.

3. The vehicle tire sensor assembly as recited in claim 1, further comprising an antenna in communication with said sensor, said antenna extended at least partially along said length of said band.

4. The vehicle tire sensor assembly as recited in claim 3, wherein said antenna is embedded within said band.

5. The vehicle tire sensor assembly as recited in claim 1, wherein said band is non-metallic.

6. The vehicle tire sensor assembly as recited in claim 1, wherein a first end of said band engages an opposite end of said band.

7. The vehicle tire sensor assembly as recited in claim 1, wherein said sensor comprises a pressure sensor.

8. The vehicle tire sensor assembly as recited in claim 1, further comprising an antenna in communication with said sensor, said antenna embedded within said band between said sensor and said power source.

9. The vehicle fire sensor assembly as recited in claim 1, wherein a first end of said band comprises a male end which passes through a female end opposite said male end of said band.

10. The vehicle tire assembly of claim 1, wherein a first end of said band comprises a male end which passes through a female end opposite said male end of said band.

11. A vehicle wheel assembly comprising:

a vehicle wheel rim having an inner diameter;

a band having a length to extend about said inner diameter;

a pressure sensor mounted along said band;

a counterweight mounted along said band spaced away from said sensor;

a power source contained within said counterweight.

12. The vehicle wheel rim assembly as recited in claim 11, wherein said pressure sensor and said counterweight are mounted along said band to locate said pressure sensor 180 degrees opposite said counterweight about said inner diameter.

13. The vehicle wheel rim assembly as recited in claim 11, further comprising an antenna in communication with said pressure sensor, said antenna extended at least partially along said length of said band.

14. The vehicle wheel rim assembly as recited in claim 13, wherein said antenna is embedded within said band.

15. The vehicle wheel rim assembly as recited in claim 11, wherein a first end of said band engages an opposite end of said band.

16. The vehicle tire sensor assembly as recited in claim 11, further comprising an antenna in communication with said sensor, said antenna embedded within said band between said sensor and said power source.

17. The vehicle tire sensor assembly as recited in claim 11, wherein a first end of said band comprises a male end which passes through a female end opposite said male end of said band.

18. The vehicle tire sensor assembly as recited in claim 11, wherein said band is non-metallic.

19. A vehicle tire sensor assembly comprising:

a non-metallic band having a length to extend about an inner diameter of a vehicle wheel rim;

a sensor mounted along said band;

an antenna in communication with said sensor and embedded within said non-metallic band; and

a counterweight mounted along said band spaced away from said sensor, wherein said counterweight comprises a power source that powers said sensor.
