Problems solved by technology

However, in such a case, it will have to penetrate the reinforcing structures present in the tire, which will deteriorate the mechanical properties of the tire
Furthermore, the airtightness of the tire will be at risk when the electrical circuit is exposed both from the inside and the outside of the tire

Embodiment Construction

[0028] refer to figure 1 , the embodiments relate to a tire 100 comprising a portion of a wear indicator 190 . Preferably, tire 100 is a pneumatic tire. Generally speaking, tire 100 has a tread 120 . Tread 120 is the portion of the tire that is configured to come into contact with surface 900 , such as a road or the ground, when tire 100 is in use. Typically, tread 120 is formed from tread blocks 110 . Correspondingly, a portion of the tread 120 is formed by the tread blocks 110 . The top surface of tread block 110 is part of tread 120 . Tire 100 may be a non-pneumatic tire. The tire 100 may be a tire for a passenger vehicle, such as a passenger car tire, such as a pneumatic tire for a passenger car. The tire 100 may be a heavy duty tire, ie a tire for heavy machines such as conveyors, loaders, trucks, tracked vehicles. The tire 100 may be a tire for motorcycles.

[0029] Wear indicator 190 includes interrogator 300 and circuit 290, as in Figure 2a1 , Figure 2a2 an...

Abstract

A tire (100) comprising a tread block (110) made of tread material, a tread (120), of which a part is formed by the tread block (110), and an insert (200) comprising a primary capacitive component (210) and a primary inductive component (220). The insert (200) extends in a longitudinal direction (z200) from a bottom (202) of the insert to a top (204) of the insert. The insert (200) has a first cross section (A1) at a first longitudinal position (r1) and a second cross section (A2) at a second longitudinal position (r2), wherein the first longitudinal position (r1) is located closer to the tread (120) of the tire (100) than the second longitudinal position (r2), and the second cross section (A2) is greater than the first cross section (A1). At least a part of the top (204) of the insert (200) does not form an interface with the tread material. A method for applying an insert into a tire (100). An insert (200) is inserted into a blind hole (112) of the tire such that the bottom (202) ofthe insert (200) is inserted deeper in the blind hole (112) than the top (204) of the insert (200).

Description

technical field [0001] The invention relates to tires with electrical wear indicators. The present invention relates to tires having wear indicators based on LC or LCR resonators whose inductance and / or oscillation frequency are configured to change as the surface of the tire wears. Background technique [0002] A remote monitoring system using LCR (inductance-capacitance-resistor) or LC (inductance-capacitance) circuits is known, for example, from document US 2005 / 0007239. Together with interrogation components, such circuits enable the monitoring of a wide variety of characteristics, including strain, temperature, pressure, identity, performance, chemical phase transitions (such as melting and solidification states), fluid levels, wear, rotational rates, position and proximity. In general, LC or LCR circuits are passive, i.e. there is no power source to convert chemical energy into electricity, even though the inductor itself is used to generate electricity through a cha...
