Description

The invention relates to a tire coupling comprising a monitored tire and a data processing system in communication with an electromagnetic wave transmitter or an electromagnetic wave transceiver, whereinthe tire has at least one fabric layer at least in regions,the fabric of the fabric layer is an electrically conductive fabric,the tissue is a component of an electrical circuit having an electrical energy source and a circuit for measuring the electrical current flowing through the tissue and / or a circuit for measuring the electrical resistance of the tissue, andthe circuit for measuring the electric current flowing through the tissue and / or the circuit for measuring the electric resistance is or are connected to the data processing system.Tire couplings serve in particular for the connection of two shafts, which in particular have hubs with clamping rings for the detachable fastening of the tires.The document DE 202 16 820 U1 discloses an elastic coupling. Two coupling parts are connected to one another by at least one tire segment, wherein the tire segment is radially clamped at its opposite edge regions by fastening means on each coupling part relative to a coupling rotational axis.Wear monitoring of the tire of the tire coupling is effected by visual monitoring of the tire, so that the tire must be regularly checked to determine whether an exchange is necessary or not. Alternatively, the clutch may be replaced at regular intervals to avoid failure.The document DE 10 2020 006 784 A1 discloses a tire coupling with a monitored tire. For this purpose, an elastic electrically conductive layer is located on at least one of the end faces of the tire of the tire coupling, which layer is a component of an electrical circuit having an electrical energy source and a circuit for measuring the electrical current flowing through the layer and / or a circuit for measuring the electrical resistance of the layer. Monitoring of the tire is limited to changing the electrical properties of the layer. A crack or wear of the tire is not detectable.The publication DE 10 2007 063 519 A1 discloses a wear and monitoring system for an elastic component, which consists of two elements that are movable relative to one another. The elements are coupled to one another via means for spring and / or damping coupling, wherein the means can have at least one elastomer component with an electrically semiconducting or conducting fabric structure. The fabric structure forms an open or closed sensor and / or circuit therein.The document DE 10 2020 006 785 A1 relates to an elastic toothed ring of a claw clutch for connecting two shafts. For this purpose, the elastic ring gear has at least one sensor device with at least one sensor for detecting the wear of the ring gear and at least one temperature sensor, wherein the sensor for detecting the wear is a sensor determining the rotation of shafts connected to one another by the claw clutch. The sensor device is connected to at least one data processing system, which is furthermore connected to an electromagnetic wave transmitter or an electromagnetic wave transceiver.The publication DE 10 2006 053 282 A1 contains an elastic shaft coupling and a method for vulcanizing at least one elastomer element. For this purpose, two coupling parts are connected to one another by at least one elastomer element. At least one sensor for detecting physical quantities of instantaneous operating or load states is vulcanized into the elastomer element. This sensor wirelessly transmits measured values to an electronic evaluation unit assigned to the clutch.The invention specified in claim 1 is based on the object of detecting damage and thus the state of a tire of a tire coupling and thus monitoring the tire coupling.This object is achieved with the features set out in claim 1.The tire coupling comprising a monitored tire and a data processing system in communication with an electromagnetic wave transmitter or an electromagnetic wave transceiver, whereinthe tire has at least one fabric layer at least in regions,the fabric of the fabric layer is an electrically conductive fabric,the tissue is a component of an electrical circuit having an electrical energy source and a circuit for measuring the electrical current flowing through the tissue and / or a circuit for measuring the electrical resistance of the tissue, andthe circuit for measuring the electric current flowing through the tissue and / or the circuit for measuring the electric resistance is or are connected to the data processing system, is characterized in particular in that damage and thus the state of the tire of the tire coupling can be detected and the tire coupling can thus be monitored.For this purpose, the fabric is applied to the tire and / or introduced into the tire in at least two layers arranged at a distance from one another. Furthermore, the layers are electrically conductively connected to one another on one side or are formed from a fabric folded over on one side.Wear and / or damage to the tire of the tire coupling as a machine element can thus advantageously be monitored simply in real time and / or automatically at intervals by means of the electrically conductive fabric of the fabric layer as a sensor. Of course, this can also be done individually. For this purpose, the tire has the electrically conductive fabric as an electrically conductive fabric layer, which is vulcanized or applied into the tire. The tissue is a component of the circuit, so that a measurement current flows in the tissue. In the event of damage and partial severing of the tissue, the electrical resistance increases since the effective cross section for the current flow through the tissue is reduced. This state is thus detectable and the measurement value resulting therefrom can be evaluated by means of the data processing system. This allows signaling and / or a warning to be carried out in accordance with the wear and / or damage to the tire.This provides permanent monitoring of the tire of the tire coupling, so that the service life of the machine element can be utilized efficiently and changeover intervals can be better planned.Advantageous embodiments of the invention are listed in the following developments and embodiments. These may further develop the tire coupling with a monitored tire and a data processing system in communication with an electromagnetic wave transmitter or an electromagnetic wave transceiver, individually or in combination.The spacing of the layers can be formed in one embodiment by means of the material of the tire.For the purpose of electrical contacting, the fabric can be connected in one embodiment to the hubs and / or clamping rings of the hubs connected to one another by means of the tire.The ends of the wrapped tissue are connected to the circuit for measuring the electric current flowing through the tissue and / or the circuit for measuring the electric resistance in one embodiment.The electric current flowing in the circuit and / or the electric resistance of the fabric is or are advantageously a measure of the wear of the tire.In one embodiment, at least one of the hubs connected to one another by means of the tire can have a sensor for measuring the temperature of the tire, which sensor is connected to the data processing system for measuring the temperature. The temperature of the tire can thus be determined during operation of the tire clutch. By means of the temperature monitoring system thus provided, errors in the design and operation of the tire can be detected and corrected. These can be incorrect assumptions regarding operating temperature and dynamic loading or installation parameters that change during operation, for example. Sudden changes in the clutch temperature make it possible in some cases to draw conclusions as to faults in the operating behavior of the installation. In addition, a possibly present temperature dependence of the electrically conductive tissue can be compensated for by the temperature measurement.In one embodiment, the data processing system can be connected to a further data processing system, to a data network and / or to at least one external data memory. The external data store can thus be a component of cloud computing. The electrically conductive fabric layer represents a sensor, wherein measured values of the sensor detected by the sensor and converted into data by the data processing system are data of the wear of the tire of the tire coupling. In addition, the data can also contain assigned location data of the tire clutch, which can thus be transmitted via a data network to a receiver and / or stored in at least one central data memory in addition to the operating data.An exemplary embodiment of the invention is illustrated in principle in the drawing and is described in more detail below.The following are shown: FIG. 1 shows a monitored tire of a tire coupling with an electrically conductive fabric as a fabric layer in the tire, FIG. 2 shows a monitored tire of a tire coupling having an electrically conductive fabric as a fabric layer on the tire, FIG. 3 shows a tire coupling with a monitored tire with an electrically conductive fabric as a fabric layer, and FIG. 4 shows a tire coupling with a monitored tire with an electrically conductive fabric as two fabric layers.A tire coupling with a monitored tire 1 substantially comprises the monitored tire 1 and a data processing system in communication with an electromagnetic wave transmitter or an electromagnetic wave transceiver.FIG. 1 shows a controllable tire 1 of a tire coupling with an electrically conductive fabric 2 as a fabric layer in the tire 1 in a basic illustration.In one embodiment, the monitored tire 1 has at least one electrically conductive fabric 2 as a fabric layer at least in regions.FIG. 2 shows a controllable tire 1 of a tire coupling with an electrically conductive fabric 2 as a fabric layer on the tire 1 in a basic illustration.In a further embodiment, the monitored tire 1 has at least one electrically conductive fabric 2 as a fabric layer on the tire 1.Advantageously, the fabric 2 is located on the inside of the monitored tyre 1.FIG. 3 shows a tire coupling with a monitored tire 1 with a fabric 2 as a fabric layer in a basic illustration.The tire coupling connects two shafts 3 by means of the tire 1, which shafts may in particular have hubs 4 with clamping rings 5 for the detachable fastening of the tire 1.The electrically conductive fabric 2 of the fabric layer of the monitored tire 1 and tire 1 thus monitored is a component of an electrical circuit comprising an electrical energy source and a circuit for measuring the electrical current flowing through the fabric 2 and / or a circuit for measuring the electrical resistance of the fabric 2. An accumulator as energy source, the circuit, the data processing system and the transmitter or transceiver are components of an electronic assembly 6. Furthermore, at least one of the hubs 4 connected to one another by means of the tire 1 can have a sensor 7 for measuring the temperature of the tire 1, which sensor is connected to the data processing system.FIG. 4 shows a tire coupling with a monitored tire 1 with an electrically conductive fabric 2 as two fabric layers in a basic illustration.In one embodiment of the monitored tire 1, the electrically conductive fabric 2 is introduced into the tire 1 in at least two layers arranged at a distance from one another. For this purpose, the layers are formed from a fabric 1 folded over on one side. The spacing of the layers is formed by means of the material of the tire 1. This advantageously allows one-sided electrical contacting of the monitored tire 1. The electrical contacting of the fabric 2 can thus take place via the hub 4 and the clamping ring 5, which for this purpose are connected to one another in an electrically non-conductive manner. The ends of the wrapped tissue 2 can thus be easily connected to the circuit for measuring the electric current flowing through the tissue 2 and / or to the circuit for measuring the electric resistance.The data processing system of the electronic assembly 6 is designed such that the electric current flowing in the circuit of the circuit and / or the electric resistance of the fabric 2 is or are a measure of the wear of the tire 1.The data processing system in connection with the electromagnetic wave transmitter or the electromagnetic wave transceiver can be connected to a further data processing system, to a data network and / or to at least one external data memory and is thus connected.The signals detected by the circuits for measuring the electric current flowing through the tissue 2 and / or for measuring the electric resistance and converted into data by means of the data processing system are data for monitoring the tire 1 of the tire coupling, so that the data for monitoring the tire coupling and location data of the tire coupling assigned to these data are data of monitoring the tire coupling that can be called up via a data network and / or stored in at least one central data memory and thus can be called up.The data can be data determined by changing the tire 1 in comparison with the data processing system with at least one limit value. The state can thus advantageously be detected via the data processing system and transmitted via the transmitter or the transceiver as a wear warning.
