Technical Field

The present invention relates to a tire.

Background

The invention proceeds from a tire which can be rotated about an axis of rotation in a direction of rotation. The tire has at least one electromagnetic transmitting and receiving device, at least one bead core and at least one apex. The at least one apex is constructed from a first uniform rubber material and a second uniform rubber material. The first uniform rubber material is disposed on at least one bead core and the first uniform rubber material is spatially disposed between the at least one bead core and the one second uniform rubber material.

In particular, the tire has at least one carcass ply.

The electromagnetic transmitting and receiving device is in particular an RFID device. RFID stands for Radio Frequency Identification (Radio Frequency Identification) and refers to Identification by means of electromagnetic waves.

Electromagnetic transmitting and receiving devices for tyres are known from the prior art. An electromagnetic transmitting and receiving device for tyres is disclosed, for example, in EP 2223814B 1.

In tyres with electromagnetic transmitting and receiving devices known from the prior art, the arrangement of the electromagnetic transmitting and receiving devices may be associated with non-optimal conditions of operation of the electromagnetic transmitting and receiving devices.

Disclosure of Invention

The invention is therefore based on the object of providing a tire with an electromagnetic transmitting and receiving device, in which case the operation of the electromagnetic transmitting and receiving device within the tire is improved.

The object according to the invention is achieved by arranging the at least one electromagnetic transmitting and receiving device inside the at least one apex.

Due to the fact according to the invention, according to which the at least one electromagnetic transmitting and receiving device is arranged inside the at least one apex, the electromagnetic transmitting and receiving device is arranged inside the area of the tyre having material homogeneity. Such material homogeneity ensures an improved operation of the electromagnetic transmitting and receiving device compared to solutions known from the prior art. Furthermore, no further use of foreign materials is required.

The dielectric properties of the material of the apex enable an optimal setting of the electromagnetic emission capability of the electromagnetic emitting and receiving device.

Accordingly, an improved tire is provided.

According to a preferred embodiment of the invention, the at least one electromagnetic transmitting and receiving device is arranged completely within the at least one apex.

According to a preferred design embodiment of the invention, the at least one electromagnetic transmitting and receiving device has an adhesion promoter coating.

Due to the fact according to the invention that the at least one electromagnetic transmitting and receiving device has an adhesion promoter coating, an improved connection of the at least one electromagnetic transmitting and receiving device within the apex can be ensured.

According to a further preferred embodiment of the invention, the at least one electromagnetic transmitting and receiving device has an information storage means and at least one antenna, wherein the at least one antenna is integrated in the yarn or the at least one antenna and the information storage means are integrated in the yarn. In particular, the at least one antenna is woven or spun into the yarn. The combination by spinning or by weaving is a special embodiment introduced. The yarns are constructed in particular from a plastic material or from a liquid-crystalline polymer.

According to the invention, the fact according to which at least one electromagnetic transmitting and receiving device has an information storage means and at least one antenna, wherein the at least one antenna is incorporated in the yarn, provides a construction of this type: this construction takes up less space within the tyre than is the case with the electromagnetic transmitting and receiving devices known from the prior art. Because the electromagnetic transmitting and receiving device occupies less space inside the tire, the likelihood of undesirable interaction with the tire is reduced.

According to a further preferred embodiment of the invention, the at least one electromagnetic transmitting and receiving device is arranged completely within the second homogeneous rubber material.

The at least one electromagnetic transmitting and receiving device is in particular completely surrounded by the second homogeneous rubber material.

According to a next preferred design embodiment of the invention, the third distance between the third surface point of the at least one electromagnetic transmitting and receiving device and the end point of the carcass ply of the tyre having a positive component in the radial direction is at least 10 mm. Thus, starting from the rotation axis, the electromagnetic transmitting and receiving means are further away from the rotation axis in the radial direction than the end points of the carcass ply.
