A bogie 1 according to an embodiment of the present invention is described below with reference to the drawings. As shown in fig. 1 to 9, a bogie 1 according to an embodiment of the present invention includes a frame 120, an axle 210, wheels 220, an axle box 110, a gear box (not shown), a first coil 310, a second coil 320, a stress detector 330, a data collector 340, and a transmitting antenna (not shown). An axle 210 is rotatably provided on the frame 120, and wheels 220 are provided on the axle 210.
A first coil 310 is provided on one of the frame 120, the axle housing 110, and the gear housing, a second coil 320 is provided on one of the axle 210 and the wheel 220, and the second coil 320 is coupled with the first coil 310 so as to receive power from the first coil 310.

A data collector 340 is electrically connected to the second coil 320 to receive electrical energy from the second coil 320, the data collector 340 being connected to the strain detector 330. The data collector 340 may be connected to the stress detector 330 in a known manner, and the data collector 340 may be electrically connected to the second coil 320 in a known manner.

The data collector 340 is connected to the transmit antenna. The data collector 340 may be connected to the transmitting antenna in a known manner, and the transmitting antenna may be electrically connected to the second coil 320 in a known manner.
The first coil 310 may be electrically connected to an external alternating current source, i.e. an alternating current may be passed to the first coil 310, so that the first coil 310 generates a varying electromagnetic field. The first coil 310 may be electrically connected to an external alternating current source in a known manner. The second coil 320 generates a current by inducing a varying electromagnetic field generated by the first coil 310. Since the data collector 340 and the transmitting antenna are electrically connected to the second coil 320, the second coil 320 may supply power to the data collector 340 and the transmitting antenna.
Since the data collector 340 is connected to the stress detector 330 and the transmitting antenna, the data collector 340 can convert the signal (e.g., resistance signal) collected by the stress detector 330 into a digital signal representing the stress, and the transmitting antenna transmits the data signal to the receiving antenna in a wireless manner. The receiving antenna may transmit the data signal to a data processing system on the train in a wired or wireless manner.

Therefore, lead holes do not need to be processed on the axle 210, the hub 221 and the web 222, so that the strength of the wheel 220 and the axle 210 is improved, the safety of the bogie 1 and the railway vehicle is improved, and the manufacturing cost of the wheel 220 and the axle 210 is reduced. In addition, since the existing structure of the parts of the bogie 1 does not need to be modified, the number of types of parts of the bogie 1 can be reduced, and the management cost can be reduced.

As shown in fig. 1-9, in some embodiments of the present invention, the bogie 1 includes a frame 120, an axle 210, wheels 220, an axle box 110, a gear box (not shown), a first coil 310, a second coil 320, a stress detector 330, a data collector 340, and a transmitting antenna. The second coil 320 is coupled with the first coil 310 to receive electrical energy from the first coil 310, i.e., electrical energy is transferred from the first coil 310 to the second coil 320. Optionally, the second coil 320 is electromagnetically inductively or resonantly coupled with the first coil 310.
The axle 210 may be mounted to the frame 120 in a known manner and the wheel 220 may be mounted to the axle 210 in a known manner. Since this is irrelevant to the point of the present application, it is not described in detail.
As shown in fig. 1 and 2, the second coil 320 is provided on an end surface of the hub 221 of the wheel 220. The first side surface of the axle housing 110 is opposed to the end surface of the hub 221 in the axial direction of the axle 210, and the first side surface of the gear housing is opposed to the end surface of the hub 221 in the axial direction of the axle 210. The first coil 310 is disposed on one of the first side of the axle housing 110 and the first side of the gear housing. The axial direction of the axle 210 is shown by arrow a in fig. 1.
The stress detector 330 may be provided on the web 222 of the wheel 220. Alternatively, the stress detector 330 may be a strain gauge. The data collector 340 and the transmitting antenna may be provided on the second coil 320, that is, the data collector 340 and the transmitting antenna may be provided on one of the axle 210 and the wheel 220 through the second coil 320. For example, the data collector 340 and the transmitting antenna may be integrated on the second coil 320.
The transmitting antenna wirelessly transmits the data signal to a receiving antenna. The receiving antenna may be provided on the body of the railway vehicle, in which case the receiving antenna may not be part of the bogie 1. The receiving antenna may also be provided on one of the frame 120, the axle box 110 and the gear box, in which case the receiving antenna may be part of the bogie 1. The receiving antenna may be connected to a power source and may also be electrically connected to the first coil 310 to receive power from the first coil 310, i.e. the first coil 310 powers the receiving antenna. The receiving antenna may be connected to a power source in a known manner, and the receiving antenna may be electrically connected to the first coil 310 in a known manner.
As shown in fig. 1, the first coil 310 and the second coil 320 are disposed opposite to each other in the axial direction of the axle 210. Thereby, the efficiency of transferring the electric energy from the first coil 310 to the second coil 320 may be improved. As shown in fig. 3 and 4, the bobbin 311 of the first coil 310 has an annular shape, and the bobbin 321 of the second coil 320 has an annular shape. The first coil 310 can thus transfer more power to the second coil 320, which can better power the data collector 340 and the transmit antenna.
As shown in fig. 5, the bogie 1 may further include a mounting bracket 130, and the mounting bracket 130 is provided on the frame 120. The first coil 310 is provided on the mount 130, the second coil 320 is provided on the axle 210, and the first coil 310 and the second coil 320 are opposed to each other in the radial direction of the axle 210. By providing the mounting bracket 130 on the frame 120 and providing the first coil 310 on the mounting bracket 130, the distance between the first coil 310 and the second coil 320 can be reduced. The efficiency of the transfer of power from the first coil 310 to the second coil 320 may thereby be increased so that the first coil 310 may transfer more power to the second coil 320 to better power the data collector 340 and the transmit antenna.
Alternatively, the frame 120 includes a vertical portion 121 and a lateral portion 122, the lateral portion 122 extends in the same direction as the axial direction of the axle 210, and the vertical portion 121 extends in the direction perpendicular to the axial direction of the axle 210. The horizontal portion 122 is connected to the vertical portion 121, and the mounting bracket 130 is provided on the horizontal portion 122.
The stress detector 330 is provided on the web 222 of the wheel 220, and the data collector 340 is provided on the axle 210. As shown in fig. 5, alternatively, the second coil 320 is provided in the middle of the axle 210 in the axial direction of the axle 210, and the data collector 340 is provided adjacent to the stress detector 330 in the axial direction of the axle 210. That is, the data collector 340 is disposed adjacent to the wheel 220 in the axial direction of the axle 210.
Since a plurality of stress detectors 330 are typically disposed on the web 222 of the wheel 220, each stress detector 330 is connected to a data collector 340 via a cable 40. By disposing the data collector 340 adjacent to the stress detector 330 in the axial direction of the axle 210, it is possible to reduce the difficulty of wiring and to shorten the length of the cable for connecting the stress detector 330 and the data collector 340. Further, by providing the second coil 320 at the middle portion of the axle 210 in the axial direction of the axle 210, it is possible to reduce the difficulty of detection due to relative movement of the components of the bogie 1.
Optionally, the data collector 340 is a flexible data collector. Therefore, the data collector 340 can be installed on the axles 210 with different diameters, and the application range of the detection device can be expanded. The flexible data acquisition unit can be well suitable for the installation of the surface of a curved surface-shaped component. For example, the flexible data collector can be well adapted to the mounting of the surface of the axle 210. Moreover, the flexible data collector can accommodate local irregularities of the mounting surface, such as local protrusions.
As shown in fig. 6, the bobbin 321 of the second coil 320 is annular, the bobbin 321 of the second coil 320 is fitted around the axle 210, and the bobbin 311 of the first coil 310 is flat. Alternatively, the first coil 310 is opposed to the second coil 320 in the extending direction of the vertical portion 121.

The efficiency of the transfer of power from the first coil 310 to the second coil 320 may thereby be increased so that the first coil 310 may transfer more power to the second coil 320 to better power the data collector 340 and the transmit antenna.
Alternatively, the bobbin 311 of the first coil 310 is arc-plate-shaped, for example, the bobbin 311 of the first coil 310 is arc-plate-shaped. Alternatively, the first coil 310 is opposed to the second coil 320 in the extending direction of the vertical portion 121.
As shown in fig. 8, the bobbin 321 of the second coil 320 is annular, the bobbin 321 of the second coil 320 is sleeved on the axle 210, the bobbin 311 of the first coil 310 is annular, and the bobbin 311 of the first coil 310 is disposed around the bobbin 321 of the second coil 320. The efficiency of the transfer of power from the first coil 310 to the second coil 320 may thereby be increased so that the first coil 310 may transfer more power to the second coil 320 to better power the data collector 340 and the transmit antenna.
Alternatively, the bobbin 321 of the second coil 320 may have a circular ring shape, and the bobbin 311 of the first coil 310 may have a circular ring shape.
As shown in fig. 9, the bobbin 321 of the second coil 320 is annular, and the bobbin 321 of the second coil 320 is fitted over the axle 210. The bobbin 311 of the first coil 310 includes a first curved portion 322, a first straight portion 323, and a second straight portion 324, the first straight portion 323 being connected to a first end portion of the first curved portion 322, and the second straight portion 324 being connected to a second end portion of the first curved portion 322. The first straight portion 323 and the second straight portion 324 are disposed opposite to each other in the radial direction of the axle 210, and the bobbin 311 of the first coil 310 is disposed around the bobbin 321 of the second coil 320. The efficiency of the transfer of power from the first coil 310 to the second coil 320 may thereby be increased so that the first coil 310 may transfer more power to the second coil 320 to better power the data collector 340 and the transmit antenna.
