Description

[0001] The invention relates to a vehicle tire.

[0002] Tire modules are used in tires for various tasks. These tasks include, for example, monitoring air pressure or measuring the temperature in the tire. Modern tire modules include an electronic module in which sensor elements and other electronic components are located. An example of such a tire module is disclosed in DE 102 43 441 A1.

[0003] A conventional method of attaching the tire module to the vehicle tire involves bonding the tire module to the inside of the tire using an adhesive.

[0004] This type of fastening may cause problems with the bonding.

[0005] The invention is based on the object of providing a vehicle tire in which a tire module in the vehicle tire can be easily connected to the vehicle tire.

[0006] The problem is solved according to the preamble and the characterizing features of claim 1 in that at least one holding means made of a flexible material is arranged on the inside of the tyre, wherein the holding means has at least one holding opening for receiving the upper side of the tire module, wherein the tire module is designed in the form of an electronic module, wherein the housing of the electronic module has a rim with which the tire module is held in the holding means.

[0007] A particular advantage of the invention is that the tire module can be connected to the vehicle tire in a simple and secure manner using the holding means.

[0008] The tire module consists of an electronic module that is not embedded in a rubber container. The electronic module, which is preferably made of plastic, has a rim on its underside that prevents the tire module from slipping through the opening of the holding module. In this way, the holding device can firmly fix the tire module to the inside of the tire with the rim.

[0009] In an advantageous development of the invention, it is provided that the rim running around the housing has a width of 5 to 15 mm.

[0010] A rim with these dimensions is sufficient to firmly fix the tire module with the retaining device on the inside of the tire.

[0011] In a further advantageous development of the invention, it is provided that the width dimension of the housing is greater than the length dimension.

[0012] The tire module contains sensors that can be used to measure acceleration and, indirectly, tire curvature. By positioning the tire module on the inside of the tire, certain signals can be measured more effectively.

[0013] In a further advantageous development of the invention, it is provided that the tire module is arranged on the inside of the tire with the length dimension in the rolling direction of the vehicle tire.

[0014] This allows the sensors in the tire module to receive and evaluate the signals received with greater accuracy.

[0015] In a further advantageous development of the invention, it is provided that the rim is wider in the direction of the width dimension of the tire module than the rim in the direction of the length dimension of the tire module.

[0016] The shorter rim in the direction of the longitudinal dimension of the tire module improves the signal processing of the sensors in the tire module.

[0017] In a further advantageous development of the invention, it is provided that the brim in the direction of the length dimension of the tire module is a maximum of 5 mm.

[0018] This rim dimension is sufficient to firmly fix the tire module to the inside of the tire. In another embodiment, a rim along the longitudinal dimension of the tire module could also be completely omitted.

[0019] In an advantageous development of the invention, it is provided that the holding means consists of a rubber material.

[0020] This ensures that the inside of the tire is not damaged.

[0021] In a further advantageous development of the invention, it is provided that the holding means is designed in the form of a flat rubber layer.

[0022] This gives the holding device a high degree of flexibility, allowing the tire module to be clamped with high strength.

[0023] In a further advantageous development of the invention, two holding means are provided one above the other.

[0024] A corresponding embodiment is shown in the Fig. 1 shown.

[0025] In a further advantageous development of the invention, the two retaining means are connected to each other via a positive connection. This ensures that the upper retaining means cannot detach itself.

[0026] In a further advantageous development of the invention, it is provided that the positive connection comprises a rectangular opening on the first holding means and a T-shaped connecting part on the second holding means, which is inserted through the rectangular opening.

[0027] This ensures that both holding devices are firmly connected to each other.

[0028] In a further advantageous development of the invention, the retaining means are integrally bonded to the tire's inner surface on one side. This firmly connects the retaining means to the tire's inner surface.

[0029] In a further advantageous development of the invention, it is provided that the material connection comprises an adhesive bond.

[0030] With an adhesive, the two retaining elements can be quickly and firmly connected to the inside of the tire.

[0031] In a further advantageous development of the invention, the retaining means are connected to the inner surface of the tire during tire production. This allows the vehicle tires to be later fitted with tire modules at the customer's site.

[0032] The invention will be explained in more detail using exemplary embodiments. They show: Fig. 1: A vehicle tire with the tire module in a radial section view. Fig. 2: The first holding device in a top view. Fig. 3: The second holding device in a top view. Fig. 4: The first and second holding means in a top view. Fig. 5: The tire module in a side view. Fig. 6: The tire module in the Fig. 5 in a supervision. Fig. 7: Another embodiment of the tire module in a top view.

[0033] Fig. Figure 1 shows an exemplary embodiment. The schematically illustrated tire module 3 includes, among other things, sensors, an electronic component with an actively transmitting element, an electronic memory, and a power supply, e.g., in the form of a battery. Tire-specific data can be stored and processed in the memory. This data can be transmitted via radio signals to receivers inside or outside the vehicle.

[0034] The tire module 3 is designed in the form of an electronic module which comprises at least one tire pressure measuring system with a pressure sensor.

[0035] The electronic module comprises a housing made of a plastic material, which has a rim on its underside with which the electronic module is fixed with the holding means shown.

[0036] The tire module 3 is fastened to the tire inner side 6 with the first holding means 4 and the second holding means 5.

[0037] Both holding elements 4 and 5 are made of a rubber material and are each connected to the inside of the tire on one side via a material-to-material connection. The material-to-material connection is, for example, an adhesive bond 7, with which the first holding element 4 is connected to the inside of the tire on the left side. The second holding element 5 is connected to the inside of the tire 6 on the right side with an adhesive bond 8. Both holding elements have a circular opening through which the tire module 3 is inserted. Since the tire module 3 has a rim on the underside, it cannot slip through the openings of the holding elements. When the tire module 3 is installed, both holding elements 4 and 5 are folded upwards.

[0038] In the embodiment, the holding means consists of two holding means 4 and 5.

[0039] The holding means could also be formed in one piece, wherein the tire module 3 would be fixed by an opening in the holding means.

[0040] In this embodiment, one retaining means would be firmly connected to the inside of the tire on two opposite sides, for example, by adhesive bonding. The retaining means would then be lifted, and the tire module 3 would be secured through the opening in the retaining means.

[0041] The Fig. Figure 2 shows the first holding means 4 in a top view. The circular holding opening 9 holds and secures the tire module, which is also circular. The rectangular opening 11 in the first holding means is used to secure the front end 12 of the second holding means.

[0042] The Fig. Figure 3 shows the second holding means 5 in a top view. The circular holding opening 10 for the tire module is located above the holding opening 9 in the first holding means 4. A T-shaped connecting part 12 is arranged at the front end of the holding means 5.

[0043] The Fig. Figure 4 shows a top view of the two retaining means 4 and 5 positioned one above the other. The top side 13 of the tire module is shown schematically on the top side. The T-shaped connecting part 12 is inserted through the rectangular opening in the first retaining means to firmly connect the two retaining means.

[0044] The Fig. 5 shows the tire module 3 in a side view. The tire module 3 consists of an electronics module with a housing. The housing of the electronics module is preferably made of a plastic material and has a circumferential rim 17 on the underside. The tire module 3 is no longer additionally embedded in a rubber container. The circumferential rim is preferably integrally connected to the housing of the tire module. The rim 17 prevents the tire module from slipping through the opening in the holding means. In this way, the tire module is firmly fixed to the inside of the tire with the rim.

[0045] The Fig. 6 shows the tire module 3 in the Fig. 5 in a top view. The width dimension 15 of the tire module is larger than the longitudinal dimension 16 of the tire module. The shorter longitudinal dimension 16 of the tire module is aligned in the rolling direction 14 of the vehicle tire. The illustrated alignment has advantages for signal detection with the sensors in the tire module. The circumferential rim 17 of the tire module has a substantially uniform width. The width of the rim is between 5 and 15 mm.

[0046] The Fig. Figure 7 shows a top view of another embodiment of a tire module. In this embodiment, the rim 18 is wider in the width direction than the rim 19 in the length direction. This ensures a firm fixation of the tire module on the inside of the tire and simultaneously improves signal detection with the sensors.
