Abstract

A ground-contacting component of a vehicle, consisting partly of polymeric compounds, in which at least one wireless temperature measurement system 7 based on surface acoustic wave or bulk acoustic wave technology is embedded in a region of a polymeric compound liable to reach temperatures above 100° C. and/or to be influenced by a surrounding region of a polymeric compound liable to reach temperatures above 100° C. during use of the vehicle. Also disclosed are a tire 1 and the use of a wireless temperature measurement system based on acoustic surface wave or bulk acoustic wave technology.

Claims

1. A ground-contacting component of a vehicle, comprising polymeric compounds, wherein at least one wireless temperature measurement system based on surface acoustic wave or bulk acoustic wave technology is embedded in a region of a polymeric compound of the polymeric compounds, the region of the polymeric compound at least one of reaching temperatures above 100°

C. and influenced by a surrounding region of a polymeric compound reaching temperatures above 100°

C. during use of the vehicle, and

wherein the at least one wireless temperature measurement system comprises at least two wireless temperature measurement systems based on surface acoustic wave or bulk acoustic wave technology, the at least two wireless temperature measurement systems comprising linearly polarized antennas and being embedded in regions of two polymeric compounds, the regions of the two polymeric compounds at least one of reaching temperatures above 100°

C. and influenced by regions of surrounding polymeric compounds reaching temperatures above 100°

C. during use of the vehicle, and an angle between 30° and

90°

is between the polarization directions of the antennas.

2. The ground-contacting component of a vehicle as claimed in claim 1, wherein the ground-contacting component is included in a mounted assembly comprising a wheel and a tire, and the ground-contacting component is part of the wheel.

3. The ground-contacting component of a vehicle as claimed in claim 1, wherein the ground-contacting component is included in a mounted assembly comprising a wheel and a tire, and the ground-contacting component is part of the tire.

4. The ground-contacting component of a vehicle as claimed in claim 1, wherein the ground-contacting component is included in a mounted assembly comprising a wheel, a tire and a support member for supporting the tire for use in a degraded mode, and the ground-contacting component is part of the support member.

5. A tire comprising at least one carcass reinforcement structure formed from reinforcing elements and anchored on each side of the tire to a bead, the base of which is mounted on a rim seat, each bead radially outwardly extended by a sidewall, the sidewalls radially outwardly joining a tread, the beads, the sidewalls and the tread comprising rubber compounds, wherein at least one wireless temperature measurement system based on surface acoustic wave or bulk acoustic wave technology is embedded in a region of a rubber compound of the rubber compounds, the region of the rubber compound at least one of reaching temperatures above 100°

C. and influenced by a surrounding region of a rubber compound reaching temperatures above 100°

C. during use of the vehicle, and

wherein the at least one wireless temperature measurement system comprises at least two wireless temperature measurement systems based on surface acoustic wave or bulk acoustic wave technology, the at least two wireless temperature measurement systems comprising linearly polarized antennas and being embedded in two regions of rubber compounds, the two regions of the rubber compounds at least one of reaching temperatures above 100°

C. and influenced by regions of surrounding rubber compounds reaching temperatures above 100°

C. during use of the vehicle, and an angle between 30° and

90°

is between the polarization directions of the antennas.

6. The tire as claimed in claim 5, wherein at least one of the measurement systems is embedded in a part of a sidewall.

7. The tire as claimed in claim 5, wherein at least one of the measurement systems is embedded in a part of a bead.

8. The tire as claimed in claim 5, wherein at least one of the measurement systems is embedded in a part of the tread.

9. The tire as claimed in claim 8, wherein at least one of the measurement systems is embedded in a part of the axially outer ends of the tread.
