Description

Technical Field

[0001] This disclosure relates to a measuring assembly for determining the characteristics of rotating components of a vehicle's rotating system.

[0002] Furthermore, this disclosure relates to a rotation system for a vehicle and the vehicle itself.

[0003] Furthermore, this disclosure relates to a method for operating a rotating system of a vehicle. Background Technology

[0004] In many rotating systems of vehicles (e.g., buses, trucks, public buses, or motorcycles), one or more characteristics of the rotating components of the rotating system are relevant to the operation of the rotating system. This also applies to research and development activities involving vehicle rotating systems. Similarly, in the context of such activities, one or more characteristics of the rotating components of the rotating system can be relevant inputs for improving and / or modifying the rotating system. In the context of this disclosure, any system comprising at least one static component and at least one rotating component rotatable relative to the static component is considered a rotating system. In such systems, the fact that the rotating component is rotatable and effectively rotates under relevant operating conditions is challenging when transmitting measurement data between the rotating component and the static component, and when powering a component of a measuring assembly located on the rotating component. Summary of the Invention

[0005] Therefore, one object of this disclosure is to further improve the measuring assembly for determining the characteristics of rotating components of a vehicle rotation system. In particular, the data transmission and power transmission of components relating to the measuring assembly located on the rotating component will be enhanced.

[0006] This problem is addressed or mitigated at least in part by the subject matter of the independent claims of this disclosure, wherein further examples are incorporated in the dependent claims.

[0007] According to a first aspect, a measuring assembly is provided for determining the characteristics of a rotating component of a vehicle's rotating system. The measuring assembly includes a first unit that can be mounted on the rotating component of the rotating system. The first unit includes an analog-to-digital converter (ADC), a first communication interface, and a first power transmission interface. The ADC and the first communication interface are communicatively connected. Furthermore, the ADC and the first power transmission interface are electrically connected. The measuring assembly also includes at least one sensor electrically connected to the ADC. Additionally, the measuring assembly includes a second unit that can be mounted on a static component of the rotating system. The second unit includes a second communication interface and a second power transmission interface. The first and second communication interfaces are wirelessly connected. Furthermore, the first and second power transmission interfaces are wirelessly connected. This measuring assembly is structurally simple. Moreover, since the first unit can be mounted on the rotating component of the rotating system and the second unit can be mounted on the static component of the rotating system, the first and second units can be reliably connected. This is suitable for communication of measurement data between the first and second units. For this purpose, the wirelessly connected first and second communication interfaces are used. Furthermore, this is suitable for power transmission from the second unit to the first unit. For this purpose, the wirelessly connected first and second power transmission interfaces are used. In other words, the first unit can be reliably powered. This allows for the reliable operation of at least one sensor and an analog-to-digital converter (ADC). The fact that the ADC is located on the first unit has the following effect: the data transmitted between the first and second units (more precisely, the measurement data) is digital. Therefore, high-quality data transmission can be ensured. In other words, digital data transmitted between the first and second units is less prone to errors and interference than analog data. In summary, the measurement assembly is simple and allows for the reliable and accurate determination of the characteristics of rotating components.

[0008] According to one example, the second unit additionally includes a wired communication interface. The wired communication interface is communicatively connected to the second communication interface. Therefore, using the wired communication interface, data originating from the first unit and describing the characteristics of the rotating component can be transmitted to a data processing device that is separate from the measurement component but communicatively connected to the measurement component via the wired communication interface. Thus, the measurement data originating from the first unit can be further processed and analyzed. According to one example, the wired communication interface is a bus interface, such as a CAN bus interface. Alternatively, the wired communication interface can be an Ethernet interface. Therefore, the measurement data can be reliably transmitted to the data processing device.

[0009] According to one example, a first communication interface includes a first wireless communication device and a second wireless communication device. Additionally, a second communication interface includes both a first wireless communication device and a second wireless communication device. The first wireless communication device of the first communication interface is communicatively connected to or can be connected to the first wireless communication device of the second communication interface. The second wireless communication device of the first communication interface is communicatively connected to or can be connected to the second wireless communication device of the second communication interface. The first and second wireless communication devices are different. In other words, each of the first and second communication interfaces includes two different wireless communication devices. Since different wireless communication devices offer different combinations of advantages and disadvantages, such as different performance under different conditions, having two different wireless communication devices provides the option to select one based on the current situation and / or the current environment. Therefore, the most suitable communication means can be selected according to the situation and / or environment. Thus, when the measurement components are considered as a whole, reliable and effective communication can be ensured for a wide variety of situations and environments. In summary, the communication of measurement data between the first and second units is particularly reliable.

[0010] According to one example, one of the first and second wireless communication devices includes a WiFi antenna. Therefore, WiFi communication can be established between the first and second units. Alternatively, one of the first and second wireless communication devices includes a Bluetooth antenna. Therefore, Bluetooth communication can be established between the first and second units. According to another alternative, one of the first and second wireless communication devices includes a Zigbee antenna. Therefore, Zigbee communication can be established between the first and second units. According to yet another example, one of the first and second wireless communication devices includes a Z-wave antenna. Therefore, Z-wave communication can be established between the first and second units. According to yet another example, one of the first and second wireless communication devices includes an infrared transmitter. Therefore, infrared communication can be established between the first and second units. According to yet another example, one of the first and second wireless communication devices includes a light source configured to emit visible light, and the corresponding other includes a photodetector configured to detect visible light. Therefore, optical communication can be established between the first and second units. Note that any of these wireless communication technologies can be used in the first communication device with a first communication interface and the second communication device with a second communication interface. In the same manner, any of the above-described wireless communication technologies can be used in the second communication device with a first communication interface and the second communication device with a second communication interface. Therefore, communication devices can be adapted to specific applications, ensuring reliable data transmission for a wide variety of applications.

[0011] According to one example, the first wireless communication device includes a WiFi antenna, and the second communication device includes an infrared transmitter. Therefore, the first wireless communication device with the first communication interface is connected or can be connected to the first wireless communication device with the second communication interface via WiFi communication, and the second wireless communication device with the first communication interface is connected or can be connected to the second wireless communication device with the second communication interface via infrared communication.

[0012] In one example, the first communication interface and the first power transmission interface are integrally formed. Additionally or alternatively, the second communication interface and the second power transmission interface are integrally formed. This means that the first communication interface is the first power transmission interface, or vice versa. Similarly, this means that the second communication interface is the second power transmission interface, or vice versa. This means that the same elements or groups of elements are used for transmitting data and transmitting power. This reduces the number of parts required for the measurement assembly. Therefore, the measurement assembly is compact and has a simple structure. In one example, the first power transmission interface may include an induction coil. The same coil can be used as an antenna configured to transmit data, i.e., as a communication interface. Similarly, the second power transmission interface may include an induction coil. The same coil can be used as an antenna configured to transmit data, i.e., as a communication interface. In these cases, the data to be transmitted can be modulated onto a signal used for power transmission.

[0013] According to one example, the measuring component includes at least two sensors connected to the same analog-to-digital converter (ADC) or different ADCs. Thus, the ADC may include two or more channels, with one sensor connected to each of the two or more channels. Alternatively, the first unit may include two or more ADCs, and at least one sensor may be connected to each of the two or more ADCs. These examples can also be combined. In such a combined example, two or more ADCs would be provided on the first unit, with two or more sensors connected to each of the two or more ADCs. In any case, having two or more sensors allows for the determination of two or more characteristics of the rotating component and / or the determination of characteristics at different locations of the rotating component. Therefore, valuable insights into the state and / or behavior of the rotating component can be provided in a precise and reliable manner.

[0014] In one example, the first unit includes a ring-shaped or curved carrier element. Additionally or alternatively, the second unit includes a ring-shaped or curved carrier element. In this case, the carrier element of the first unit is configured to carry components of the first unit. Optionally, the carrier element of the first unit is further configured to connect components of the first unit to a rotating component. Similarly, the carrier element of the second unit is configured to carry components of the second unit. Optionally, the carrier element of the second unit is further configured to connect components of the second unit to a static component. Both the carrier element of the first unit and the carrier element of the second unit can include a printed circuit board. Furthermore, the ring-shaped or curved shape of the carrier element of the first unit and the carrier element of the second unit facilitates mounting and integrating the carrier element of the first unit onto the rotating component and mounting and integrating the carrier element of the second unit onto the static component. Note that the ring-shaped or curved shape represents a general appearance of the carrier element and is not limited to a specific outer or inner contour. In one example, the outer and / or inner contour of the carrier element is circular or arc-shaped. In another example, the outer and / or inner contour of the carrier element is polygonal, such as hexagonal or octagonal. For both the carrier elements of the first and second units, the carrier elements need to be sized in a compact manner. Furthermore, the carrier elements of the first unit need to be designed in a way that does not generate significant air resistance or noise. This can be achieved by using carrier elements with a ring-shaped or curved design. For ease of communication and power transmission, it is advantageous for the carrier elements of the second unit to have a shape similar to that of the carrier elements of the first unit.

[0015] In an example where the carrier elements of the first and second units are annular, the first and second units are particularly suitable for mounting on a rotating and a static component, respectively, such that the first and second units face each other along the axis of rotation. In another example where the carrier elements of the first and second units are curved, the first and second units are particularly suitable for mounting on a rotating and a static component, respectively, such that the first and second units face each other in the radial direction, wherein the radial direction is determined with reference to the axis of rotation of the rotating component.

[0016] In one example, the carrier element of the first unit and / or the carrier element of the second unit comprises a ferromagnetic material. The ferromagnetic material can enhance power transmission and / or communication between the first unit and the second unit.

[0017] According to one example, a first power transmission interface and a second power transmission interface are inductively connected. This allows for efficient and reliable power supply to the components of the first unit (specifically, the analog-to-digital converter). In this document, the first and second power transmission interfaces can be configured to communicate, such that the first power transmission interface can transmit a power demand or request to the second power transmission interface. Based on this, the second power transmission interface can provide the necessary power, for example, by adjusting the frequency of power transmission.

[0018] In one example, at least one sensor includes one or more of a temperature sensor, a strain sensor, a resistance sensor, and a voltage sensor. Temperature, strain, resistance, and voltage are relevant parameters of a vehicle's rotating system. Therefore, having measurement data indicating temperature, strain, resistance, and / or voltage allows for improvements in the operation of the rotating system. Note that strain measurements can indicate torque. Furthermore, such measurement data is valuable when developing and / or enhancing rotating systems used in vehicles.

[0019] In an example where at least one sensor includes a temperature sensor, the temperature sensor may include a thermocouple and / or a resistance temperature detector. Therefore, accurate measurement data indicating temperature can be provided.

[0020] According to a second aspect, a rotation system for a vehicle is provided. The rotation system includes a static component. Furthermore, the rotation system includes a rotating component rotatable about an axis relative to the static component. Additionally, the rotation system includes a measuring assembly according to a first aspect of this disclosure. A first unit of the measuring assembly is mounted on the rotating component, and a second unit of the measuring assembly is mounted on the static component. Such characteristics are applicable to the vehicle's rotation system because the measuring assembly is simple and allows for reliable and accurate determination of the characteristics of the rotating component. Based on this, the operation of the rotation system can be enhanced. Furthermore, these characteristics can be used when modifying or further developing such a rotation system.

[0021] In the context of a rotating system, a rotating component may include or may be a shaft.

[0022] In one example, the first and second units face each other axially or radially. Therefore, in the first alternative, the main communication direction and the main power transmission direction are axially oriented, i.e., extending along the axis of rotation. In the second alternative, the main communication direction and the main power transmission direction are radially oriented, with the radial direction based on the axis of rotation. In both examples, communication and power transmission can be accomplished in a highly reliable manner.

[0023] In one example, the distance between the first and second units is 1 mm to 10 mm. This range has been found to be particularly suitable because it allows for reliable communication and power transmission. Simultaneously, it allows for sufficient separation of the first and second units. This applies to both mechanical and electrical aspects. Therefore, undesirable mechanical and / or electrical interactions between the first and second units are avoided.

[0024] In one example, the rotating system is an electric motor. Alternatively, the rotating system is a braking system. Further alternatively, the rotating system is a mechanical transmission. When the rotating system is an electric motor, the rotating component may include a rotor or may be the rotor of an electric motor. Optionally, the rotating component may also include a mechanical shaft. The static component may be a stator or may include the stator of an electric motor. When the rotating system is a braking system, the rotating component may include a rotatable axle, wheel hub, or brake disc configured to be connected to the wheels of a vehicle. The static component may be a carrier component, such as a chassis component or a brake caliper. When the rotating system is a mechanical transmission, the rotating component may include a rotatable shaft or gear. The static component may be a static component of the mechanical transmission, such as a housing portion. In all these alternatives, at least one characteristic of the rotating component can be reliably and accurately determined. This characteristic can be used for the operation and / or further development of the rotating system.

[0025] Note that the measuring component according to the first aspect of this disclosure can be oil-resistant. This means that the measuring component is designed to operate in environments including oil. In particular, if the measuring component or its components come into contact with oil, the operation of the measuring component is not affected. This further enhances the reliability and versatility of the measuring component.

[0026] According to a third aspect, a vehicle is provided. The vehicle includes a rotation system according to a second aspect of this disclosure. Therefore, the vehicle also includes a measuring component according to a first aspect of this disclosure. Since the measuring component is simple and allows for reliable and accurate determination of the characteristics of the rotating components, such characteristics can be used in the rotation system of the vehicle, and therefore in the vehicle itself. Based on this, the operation of the rotation system and the vehicle can be enhanced. Furthermore, these characteristics can be used when modifying or further developing such a rotation system and vehicle.

[0027] According to a fourth aspect, a method for operating a rotating system of the second aspect of this disclosure is provided. The method includes transmitting measurement data from a first unit to a second unit, wherein the measurement data is digital. Therefore, high-quality data transmission can be ensured. In other words, digital data transmitted between the first and second units is less prone to errors and interference than analog data. In summary, the measurement component allows for reliable and accurate determination of the characteristics of rotating components.

[0028] In one example, measurement data is transmitted using either a first or a second communication device based on the operating parameters of the rotating system. Since different wireless communication devices offer different combinations of advantages and disadvantages, such as varying performance under different conditions, having two different wireless communication devices provides the option to select one based on the operating parameters of the rotating system. Therefore, the most suitable communication method can be selected according to the operating parameters. This ensures reliable and efficient communication.

[0029] In one example, the operating parameter is the rotational speed of the rotating component. Therefore, either a first or second communication device can be selected based on the rotational speed of the rotating component. Thus, reliable communication can be established when the rotating component rotates relatively quickly and when it rotates relatively slowly. In one example, WiFi communication is used when the rotating component rotates relatively slowly, and infrared communication is used when it rotates relatively quickly.

[0030] It should be noted that the above examples can be combined with each other, regardless of the aspects involved.

[0031] These and other aspects of this disclosure will become apparent and clear with reference to the examples described below. Attached Figure Description

[0040] Figure 8 It shows including Figure 1 or Figure 4 Test bench for rotating systems. Detailed Implementation

[0041] The accompanying drawings are merely illustrative and are intended to illustrate examples of this disclosure only. In principle, identical or equivalent elements have the same reference numerals.

[0042] Figure 1 A rotation system 10 for a vehicle is shown. Only the components of the rotation system 10 that are essential for the following explanation are shown.

[0043] exist Figure 1 In the example, the rotating system 10 is a motor configured to drive the vehicle. This means... Figure 1 The motor can be designated as a traction machine.

[0044] The rotating system 10 includes a static component 12, in Figure 1 In the example, the static component 12 includes a stator 14 of the motor and a base element 16, with the stator 14 mounted on the base element 16.

[0045] Furthermore, the rotating system 10 includes a rotating component 18. The rotating component 18 is rotatable about axis A relative to the static component 12.

[0046] exist Figure 1 In the example, the rotating component 18 includes a rotor 20 of a motor and a shaft 22 of the motor mechanically connected to the rotor 20.

[0047] For ease of illustration, the remaining components of the motor are not shown.

[0048] The rotating system 10 also includes a measuring component 24.

[0049] Measuring component 24 is configured to determine a characteristic of the rotating component 18. In this example, the characteristic is temperature. Therefore, measuring component 24 is configured to determine the temperature of the rotating component 18.

[0050] The measuring components include a first unit 26.

[0051] The first unit 26 includes an annular carrier element 28 (see also...) Figure 2 ), its in Figure 1 The example is formed by a ring-shaped printed circuit board.

[0052] In addition, the first unit 26 includes a first communication interface 30 and a first power transmission interface 32.

[0053] The first communication interface 30 includes a first wireless communication device 34 and a second wireless communication device 36, wherein the first wireless communication device 34 and the second wireless communication device 36 are different.

[0054] In this example, the first wireless communication device 34 includes a WiFi antenna. This means that the first wireless communication device 34 is a WiFi transceiver.

[0055] Furthermore, in this example, the second wireless communication device 36 includes an infrared transceiver. Therefore, infrared communication can be established using the second wireless communication device 36.

[0056] The first power transmission interface 32 is configured to transmit power inductively. Therefore, the first power transmission interface 32 includes an induction coil.

[0057] The first communication interface 30 (i.e., the first wireless communication device 34 and the second wireless communication device 36) and the first power transmission interface 32 are both mounted on the carrier element 28 (see [link]). Figure 2 ).

[0058] It should be noted that, Figure 2 The first power transmission interface 32 and the first communication interface 30, which includes the first wireless communication device 34 and the second wireless communication device 36, are shown only schematically.

[0059] Additionally, the first unit 26 includes an analog-to-digital converter 38, which is also mounted on the carrier element 28. The analog-to-digital converter 38 is also shown schematically only.

[0060] The analog-to-digital converter 38 is communicatively connected to the first communication interface 30. Furthermore, the analog-to-digital converter 38 is electrically connected to the first power transmission interface 32.

[0061] Note that the first unit 26 also includes a data processing unit configured to control one or more of the analog-to-digital converter 38, the first communication interface 30, and the first power transmission interface 32. The data processing unit can be a separate component communicatively connected to the relevant interface among the analog-to-digital converter 38, the first communication interface 30, and the first power transmission interface 32. Alternatively, the data processing functions of the data processing unit can be integrated into one or more of the analog-to-digital converter 38, the first communication interface 30, and the first power transmission interface 32. This means that the data processing functions can be distributed. For ease of illustration, the data processing unit is not shown in the figure.

[0062] To enhance the functionality of the first power transmission interface 32, a ferromagnetic material layer 39 is provided on the carrier 28.

[0063] The first unit 26 is mounted on the rotating component 18. Figure 1 In the example, this is accomplished via a disc retainer located at the end of shaft 22.

[0064] The measuring component 24 further includes at least one sensor 40. Since the measuring component 24 is configured to detect temperature in this example, the sensor is a temperature sensor. More specifically, in this example, the temperature sensor is a resistance sensor, such as a PT 100 sensor.

[0065] Sensor 40 is arranged on rotating component 18.

[0066] In addition, sensor 40 is connected to analog-to-digital converter so that the analog measurement signal generated by sensor 40 can be transmitted to analog-to-digital converter 38.

[0067] Note that, for ease of explanation, we will combine... Figure 1 The example only mentions one sensor 40. However, multiple sensors 40, for example, distributed on the rotating component 18, can be used. Multiple sensors can be connected to the same analog-to-digital converter 38. Alternatively, multiple analog-to-digital converters 38 can be provided, and different sensors 40 can be connected to different analog-to-digital converters 38. Variations including more than one sensor 40 are also possible. Figure 6 As shown in the diagram, it will be explained further below.

[0068] The measuring component also includes a second unit 42.

[0069] The second unit 42 also includes the annular carrier element 44 (see also...). Figure 3 ), its in Figure 1 The example is formed by a ring-shaped printed circuit board.

[0070] In addition, the second unit 42 includes a second communication interface 46 and a second power transmission interface 48. Both the second communication interface 46 and the second power transmission interface 48 are disposed on the annular carrier element 44.

[0071] The second communication interface 46 includes a first wireless communication device 50 and a second wireless communication device 52, wherein the first wireless communication device 50 and the second wireless communication device 52 are different.

[0072] In this example, the first wireless communication device 50 includes a WiFi antenna. This means that the first wireless communication device 50 is a WiFi transceiver.

[0073] Furthermore, in this example, the second wireless communication device 52 includes an infrared transceiver. Therefore, infrared communication can be established using the second wireless communication device 52.

[0074] The second power transmission interface 48 is configured to transmit power inductively. Therefore, the second power transmission interface 48 includes an induction coil.

[0075] It should be noted that, Figure 3 The second power transmission interface 48 and the second communication interface 46, which includes the first wireless communication device 50 and the second wireless communication device 52, are shown only schematically.

[0076] To enhance the functionality of the second power transmission interface 48, a ferromagnetic material layer 54 is provided on the carrier 44.

[0077] In addition, the second unit 42 includes a wire-bound communication interface 56, which in this example is a CAN bus interface.

[0078] Note that the second unit 42 also includes a data processing unit configured to control one or more of the second communication interface 46, the second power transmission interface 48, and the wired communication interface 56. The data processing unit can be formed as a separate component of the second unit 42, communicatively connected to the relevant interface among the second communication interface 46, the second power transmission interface 48, and the wired communication interface 56. Alternatively, the data processing functions of the data processing unit can be integrated into one or more of the second communication interface 46, the second power transmission interface 48, and the wired communication interface 56. This means that the data processing functions can be distributed. For ease of illustration, the data processing unit is not shown in the figure.

[0079] Also note that the second unit 42 includes a wired power interface configured to power the components of the second unit 42. This wired power interface is not shown in the figure.

[0080] The second unit 42 is mounted on the static component 12. Figure 1 In the example, this is accomplished via a disc retainer disposed on the base element 16.

[0081] Therefore, in Figure 1 In the example, the first unit 26 and the second unit 42 are mounted such that they face each other along axis A (i.e., along the axial direction). The distance between the first unit 26 and the second unit 42 is 1 mm to 10 mm.

[0082] Furthermore, the first power transmission interface 32 and the second power transmission interface 48 are inductively connected. This means that the first power transmission interface 32 and the second power transmission interface 48 are wirelessly connected. Therefore, power can be transmitted to the first unit 26. The transmission of power is independent of the movement (more precisely, rotation) of the rotating component 18. This means that power can be transmitted independently of whether the rotating component 18 rotates or not.

[0083] Furthermore, the first communication interface 30 and the second communication interface 46 are wirelessly connected. More precisely, the first wireless communication device 34 of the first communication interface 30 is wirelessly connected to the first wireless communication device 50 of the second communication interface 46.

[0084] In addition, the second wireless communication device 36 of the first communication interface 30 is wirelessly connected to the second wireless communication device 52 of the second communication interface 46.

[0085] Therefore, the rotation system 10, including the measuring component 24, can operate as follows.

[0086] Sensor 40 generates an analog signal. Figure 1 In the example, the measurement signal indicates the temperature of the rotating component 18.

[0087] The measurement signal is transmitted to an analog-to-digital converter 38, where it is converted into a digital signal indicating the temperature of the rotating component, which is also designated as measurement data.

[0088] Subsequently, digital measurement data indicating the temperature of the rotating component 18 can be transmitted to the second unit 42 using the first communication interface 30 and the second communication interface 46. As previously mentioned, both the first communication interface 30 and the second communication interface 46 include two wireless communication devices 34, 36, 50, and 52.

[0089] The first wireless communication devices 34 and 50 and the second communication devices 36 and 52 are redundant. This means that, in principle, the first wireless communication devices 34 and 50 or the second communication devices 36 and 52 can be used to transmit digital measurement data.

[0090] However, based on the operating parameters of the rotating system 10, the first wireless communication device 34, 50 or the second communication device 36, 52 may be more suitable for transmitting measurement data.

[0091] exist Figure 1 In the example, the operating parameter of the rotating system 10 is the rotational speed of the rotating component 18.

[0092] Therefore, if the rotational speed of the rotating component 18 is lower than a predetermined rotational speed threshold, the first wireless communication devices 34 and 50 are used. Otherwise, if the rotational speed of the rotating component 18 is equal to or exceeds the predetermined rotational speed threshold, the second communication devices 36 and 52 are used. As previously described, in this example, the first communication devices 34 and 50 are configured to provide WiFi communication, while the second communication devices 36 and 52 are configured to provide infrared communication.

[0093] Once digital measurement data is received at the second unit 42, the measurement data can be further transmitted to a data processing device, which can be communicatively connected to the second unit 42 via a wired communication interface 56.

[0094] Figure 4 and Figure 5 A rotating system according to a second example is shown, which includes a measuring component 24 according to the second example. In the following, only the combination of... Figures 1 to 3 The explanation differs from the first example. Otherwise, the above explanation applies to the variant example.

[0095] The first difference involves the fact that in the second example, the carrier element 28 of the first unit and the carrier element 44 of the second unit are curved. More precisely, both carrier element 28 and carrier element 44 are sheet-shaped, wherein the sheet is curved.

[0096] As previously mentioned, both carrier element 28 and carrier element 44 include printed circuit boards, which in the second example provide sufficient flexibility to be bent.

[0097] Therefore, the carrier element 28 of the first unit 26 is mounted on the side surface of the cylindrical element of the rotating component 18. Figure 4 and Figure 5 In the example, the carrier element 28 of the first unit 26 is mounted on a side surface of a portion of the shaft 22.

[0098] Furthermore, the carrier element 44 of the second unit 42 is mounted on the side surface of the cylindrical element. However, this cylindrical element is now an element of the static component 12. Figure 4 and Figure 5 In the example, the carrier element 44 of the second unit 42 is mounted on the inner side surface of a portion of the stator 14.

[0099] Furthermore, in the second example, the first unit 26 and the second unit 42 are arranged such that they face each other in the radial direction. This radial direction is determined based on the direction of the axis of rotation A.

[0100] Note that although the first communication interface and the first power transmission interface have been presented as separate entities in the above example, they can alternatively be formed as a single entity. In such an alternative, the induction coil of the first power transmission interface also serves as the antenna of the first communication interface. Similarly, even though the second communication interface and the second power transmission interface have been presented as separate entities, they can alternatively be formed as a single entity. In such an alternative, the induction coil of the second power transmission interface also serves as the antenna of the second communication interface.

[0101] exist Figure 6 In the diagram, the components of the measurement system 24 are represented by a block diagram. Therefore, Figure 6 The representation covers both the first and second examples. Furthermore, in Figure 6 The diagram shows the use of more than one sensor 40.

[0102] Despite Figure 6 In this configuration, multiple sensors 40 are connected to one analog-to-digital converter 38; alternatively, the first unit 26 may also include two or more analog-to-digital converters 38. In this case, one or more sensors may be connected to each of the two or more analog-to-digital converters 38.

[0103] Both the rotating system according to the first example and the rotating system 10 according to the second example can be used in vehicle 58. This is in Figure 7 As shown in the image.

[0104] As in Figures 1 to 5 In the example, the rotating system 10 can be an electric motor. In the example where the rotating system 10 is used in a vehicle 58, the motor can be an electric traction machine for the vehicle 58. Therefore, the measurement data provided by the measuring component 24 can be used during the operation of the vehicle 58, or can be collected for research and development purposes.

[0105] Alternatively, the rotation system 10 according to the first example and the rotation system 10 according to the second example can be used in the test bench 60. Figure 8 As shown in the image.

[0106] As in Figures 1 to 5 In the example where the rotating system 10 is used for the test bench 60, the rotating system 10 can be a motor. Therefore, the measurement data provided by the measuring component 24 can be used for research and development purposes.

[0107] Note that even in the foregoing example, sensor 40 is a temperature sensor; alternatively, sensor 40 can also be configured to detect characteristics of the rotating component 18 that differ from temperature. In a first alternative, sensor 40 may include a strain sensor, enabling the detection of mechanical strain occurring in the rotating component 18. Note that strain in the rotating component 18 can indicate torque. This may be useful if the rotating component 18 is a mechanical shaft or includes a mechanical shaft. Alternatively, sensor 40 can be configured and used to detect resistance and / or voltage.

[0108] It should also be noted that although the above example involves a rotating system 10 as a motor, in another example, the rotating system could also be a braking system or a mechanical transmission device.

[0109] When the rotating system 10 is a braking system, the rotating component 18 may include a rotatable axle, wheel hub, or brake disc configured to be connected to a wheel. The static component 12 may be a carrier component, such as a chassis component or a brake caliper.

[0110] When the rotating system 10 is a mechanical transmission device, the rotating component 18 may include a rotatable shaft or gear. The static component 12 may be a static component of the mechanical transmission device, such as a housing component.

[0111] In addition, the above explanation, with necessary modifications, applies to rotating system 10 as an example of a braking system or mechanical transmission device.

[0112] As used herein, the phrase “at least one” in relation to a list of one or more entities should be understood to mean at least one entity selected from any one or more entities in the entity list, but not necessarily including at least one of each entity specifically listed in the entity list, and does not exclude any combination of entities in the entity list. This definition also allows for the optional presence of entities other than those specifically identified in the entity list referred to by the phrase “at least one,” whether related to or unrelated to those specifically identified entities. Thus, as a non-limiting example, “at least one of A and B” (or equivalently, “at least one of A or B”, or equivalently, “at least one of A and / or B”) in one example may refer to at least one A, optionally including more than one A, while B is absent (and optionally including entities other than B); in another example, it refers to at least one B, optionally including more than one B, while A is absent (and optionally including entities other than A); and in yet another example, it refers to at least one A, optionally including more than one A, and at least one B, optionally including more than one B (and optionally including other entities). In other words, the phrases “at least one,” “one or more,” and “and / or” are open-ended expressions that are both connected and separate in operation. For example, each of the expressions “at least one of A, B, and C,” “at least one of A, B, or C,” “one or more of A, B, and C,” “one or more of A, B, or C,” and “A, B, and / or C” can mean a single A, a single B, a single C, A and B together, A and C together, B and C together, A, B, and C together, and optionally any of the above combined with at least one other entity.

[0113] By studying the accompanying drawings, the disclosure, and the appended claims, those skilled in the art can understand and implement other variations of the disclosed examples in practice with respect to the claimed disclosure. In the claims, the word "comprising" does not exclude other elements or steps, and the indefinite articles "a" or "an" do not exclude multiple. A single processor or other unit can perform the function of several items or steps recited in the claims. The fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used advantageously. Computer programs can be stored / distributed on suitable media, such as optical storage media or solid-state media provided with or as part of other hardware, but can also be distributed in other forms, such as via the Internet or other wired or wireless telecommunications systems. Any reference numerals in the claims should not be construed as limiting the scope of the claims.
