Description

A TIRE MEASURING SYSTEM WITH FLEXIBLE BELT Subject of the Invention and Technical Field This invention relates to a tire measuring system with a flexible belt which allows to measure the pressure of the tire on the rim. The invention relates to a belt configuration and therefore a measuring system, wherein the belt configuration is designed in such a way that the measuring instrument is minimally affected by vibration between the wheel rim and the sensor from which wheel pressure information is obtained; it is resistant to high temperatures; a part thereof is made of elastic material and the rest is made of polyester material. State of the Art Today, tires need to fulfill tasks and criteria such as to carry the stationary car, to resist the large load transfers which occur at the time of starting and braking, to transfer the power of the engine to the road when braking and cornering, to last safely and for a long time for a pleasant ride, to steer the vehicle safely regardless of the road condition and climatic conditions, to ensure the comfort of the driver and passengers, to reduce the effect of roughness on the road for the longevity of the vehicle and to be durable by keeping its performance at the highest level for millions of wheel revolutions. It is very important that the tires are inflated at the right rate. Properly inflated tires provide better stability, handling and braking, therefore, tires without the right pressure can lead to fatal accidents. In addition, tires with the right amount of pressure have a longer service life, thus saving costs, time and labor. There are systems which monitor the pressure of the tires. Among the various solutions for fixing the electronic unit on a wheel to measure pressure and temperature parameters, there is a thin strip made of metal, which consists in fixing said unit to the rim by strapping. Its dimensions are adapted to those of the rim and have the same characteristics as a clamp, which in particular includes a clamping screw. This strip is passed through the strip by being passed through the bottom of the case or through the windows located at the bottom of the case and closed around the perimeter of the rim. During the installation and disassembly stages of this structure known in the state of the art, the case poses an obstacle to the movement the tire on the rim. As a matter of fact, at these stages, the sidewalls of the tire transmit the forces to the upper part of the sensor. Since this upper part is the farthest from the connection point located in the lower part, the torque transmitted to the case and the rim is maximum. In the known state of the art, in systems where metal connections are used, metal parts lose their tension at high temperatures and loosen by vibration. This causes displacement in the sensor position, vehicle vibration, noise and deterioration in vehicle balance. In the known state of the art, in systems where metal connections are used, metal connections require special apparatus for stretching and tightening, which causes assembly to be difficult, which increases the cost of production, assembly and labor. In the known state of the art, in systems where metal connections are used, the electronic system cannot be protected from high temperatures and damages the electronic system by increasing the temperature level, causing special production resistant to high temperatures in order to prevent damage to the electronic system. In the known state of the art, the metal connections used in the tires transfer heat to the electronic system and cause a reduction in the tire durability and pressure, vehicle vibration and noise in the vehicle caused by vibration, and the deterioration of the vehicle balance, it has become a necessity to put forward solutions which are resistant to high temperatures, do not cause vibration and noise, do not disturb the balance of the vehicle, are more durable and robust, easy to assemble and have low production costs. While the metal structure in the known state of the art provides rigidity, being affected by vibrations, noise, and assembly difficulties are among the important disadvantages. Application with No. US10525778B2 known in the literature relates to a system aiming easily fixing of the measuring sensors, such as pressure sensors, on the vehicle's rim. The system secures the measuring sensors on the rim by means of a tension belt. The belt used is made of a special material and shortens upon heating, and its two ends can be fixed to each other by means of fasteners. The system enables the assembly of the measuring sensors by applying heat to the rim and stretching the belt. As can be seen in the above-mentioned patent application, there are patent/utility model applications which measure tire pressure in the known state of the art. However, in the applications filed, there was no mention of the measuring instrument with a connection system between the high-temperature resistant dual-material ri
