る。This object is achieved in a device of the type mentioned at the outset in which a transponder is provided on a piston element, which piston element is movable into a cap-shaped valve housing which is screwed into a tire valve of a motor vehicle wheel. The valve housing is made of a material that shields the electromagnetic antenna area, and a spring device is provided between the piston element and the valve housing, the valve housing and the piston element forming a piston-cylinder unit, This is achieved by the fact that the piston element is biased by the tire pressure when the cylinder unit is screwed into the tire valve and the pressure acting on the piston element and the spring force of the spring device act in opposite directions. Advantageous embodiments of the invention are described in the respective claims.

取り扱われる。The device according to the invention makes it easy to handle the composite body which, in combination with the valve housing and the piston element provided therein, forms the piston-cylinder unit, can be easily mounted on a tire valve of a motor vehicle wheel. This has the advantage that the tire pressure can be detected. The piston-cylinder unit is handled much like a dust protection cap on a tire valve of a vehicle wheel.

発生される。With the device according to the invention, it is possible to contactlessly detect a signal corresponding to the respective tire pressure and to evaluate this with an evaluation circuit connected to the antenna. The stationary antenna is provided, for example, on the wheel box or on the side cover of the vehicle wheel. Each time the vehicle wheel rotates, a transponder mounted on the tire valve of the vehicle wheel traverses the electromagnetic antenna area of the fixed-position antenna and produces a signal which is evaluated by the evaluation circuit. When the tire pressure falls below a certain critical critical value during driving, the movement of the piston and thus the transponder on the piston element into the valve housing takes place. Movement into this valve housing
The pressure of the tire pressure is caused by a spring device which no longer acts in opposition. Since the valve housing is made of a material that shields the electromagnetic antenna area, if the transponder sinks into the valve housing, the electromagnetic shielding of the transponder takes place and the antenna no longer senses signals. The evaluation circuit can be designed in such a way that all tires of the motor vehicle can be monitored and an audible and / or visual alarm is generated in the absence of a transponder signal.

が達成される。It is advantageous for each transponder to be provided with its own coding device in order to unambiguously accommodate the pressure losses that occur in the vehicle tires on the vehicle wheels. Such a coding device can be realized, for example, in a transponder ROM chip (read-only memory). When the valve housing is made of a highly transparent metal, in particular μ-metal, a reliable functional shielding of the electromagnetic antenna area is achieved.

きる。The device according to the invention is designed for any tire standard pressure, that is to say that it can be used for trucks or passenger cars by proper selection of the spring device used. That is, by properly selecting the spring device, a spring device having an appropriate spring characteristic can be adopted. However, when an adjusting device is used which can adjust the bias pressure of the spring device used, the device according to the invention with a given spring device can be adapted to any tire standard pressure.

ジングとの間の適当なパッキンによって実現できる。When the device according to the invention is arranged on the tire valve, that is, screwed on, the valve needle of the tire valve is actuated to open the tire valve with the piston-cylinder unit screwed onto the tire valve. Therefore, the piston of the piston / cylinder unit is biased by the tire pressure on the side opposite to the spring device. This means that the piston-cylinder unit must be sealed to the outside when screwed into the tire valve. This can be achieved by suitable packing between the piston element and the valve housing.

を及ぼされる。Appropriate air pressure for trucks and tires is particularly important in the transportation industry. This is comparable to a brake / antilock device from a safety point of view for the following reasons. -Track and tire defects are due at least to crazy tire pressures. -If a tire breaks, not only will it have to be replaced with a new one (which will be reasonably costly), but also the costs associated with shutdown and tire replacement. -The tire heats so hard that it starts to burn due to too low tire pressure, which puts the entire truck at risk.
