Description

Technical Field

[0001] This utility model relates to the field of bogie technology, specifically a bogie for rail vehicles. Background Technology

[0002] A bogie is an important component installed on rail transit vehicles such as trains and trams. It supports the vehicle body and provides steering function. Located at the bottom of the vehicle, it connects the wheels and the vehicle body and can rotate to achieve steering when the vehicle is in motion. The bogie is usually composed of axles, wheelsets, springs, suspension system, and steering mechanism connected to the vehicle body. Its design and performance have a significant impact on the vehicle's stability, handling, and ride comfort.

[0003] Application announcement number CN118124628A provides a railway vehicle bogie, including a bogie body, with wheels installed at each of the four corners of the bogie body. A base plate is fixedly connected to the lower surface of the bogie body, and a fixing frame is fixedly connected to each of the four corners of the base plate. The device can clean the surface of the wheels using a cleaning brush, preventing debris from accumulating on the wheels and causing damage or surface corrosion. However, after long-term use, a large amount of impurities and dust remain on the surface of the cleaning brush head, severely affecting its cleaning effect on the wheel surface. Frequent cleaning by operators is required, impacting the overall performance. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a bogie for rail vehicles.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

One side of the force plate is provided with several protrusions along the axial direction. The other side of the pressure plate is elastically connected to the bracket with an elastic reset member, and the brush head is driven to move towards the wheel by the elastic force.

[0010] The follower is rotatably mounted on the bracket and can abut against the wheel. It includes a push rod that can rotate synchronously in the opposite direction with the wheel, and the rotation path of the push rod passes through the force plate.

[0011] When the pressure plate rotates under the pressure of the force plate and the push rod, the brush head disengages from the wheel and is subjected to the pressure of the protrusion and the push rod, generating vibrations that transmit to the residual impurities on its surface.

[0012] Preferably, the cross-section of the plurality of protrusions is semi-circular, and their diameter increases linearly along the extension direction of the force-bearing plate.

[0013] Preferably, the elastic reset element is one of a compression spring, a tension spring, or a torsion spring.

[0014] Preferably, the brush head is provided with a plurality of bolt fasteners that slide through the pressure plate.

[0015] Preferably, a drive component is hinged between the bracket and the crossbeam of the bogie body, which can drive the bracket to rotate until the follower and brush head disengage from the wheel.

[0016] Preferably, the follower includes a roller rotatably mounted on the bracket, a drive gear is provided on one side of the roller, a driven gear meshing with the drive gear is rotatably mounted on the bracket, and the push rod is located on the outer edge of one side of the driven gear.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: by using the brush head and pressure plate together, the brush head can be pressed against the surface of the wheel to clean impurities, avoiding wheel damage or corrosion caused by the accumulation of impurities; at the same time, with the cooperation of the follower and the force plate, vibration can be generated and transmitted to the brush head to remove residual impurities on the surface of the brush head, solving the problem of traditional cleaning brushes getting dirtier the more they are used, and ensuring stable long-term cleaning effect.

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] Example

[0026] like Figures 1-4 As shown, a rail vehicle bogie includes a bogie body 1.

[0027] Cleaning component 2, located on the wheel side of bogie body 1, includes:

[0028] The bracket 20 is rotatably mounted on the crossbeam of the bogie body 1. A drive component 201 is hinged between the bracket 20 and the crossbeam of the bogie body 1, which can drive the bracket 20 to rotate until the follower 22 and the brush head 211 are disengaged from the wheel. The drive component 201 can be an electric push rod, a hydraulic cylinder or a pneumatic cylinder. As the basic support structure of the cleaning component 2, it provides an installation carrier for the pressure plate 21 and the follower 22. At the same time, through the hinged cooperation with the drive component 201, the overall position adjustment of the cleaning component 2 can be realized, avoiding wear of parts in non-cleaning state, extending service life, and facilitating maintenance or idleness.

[0029] The pressure plate 21 is rotatably mounted on the bracket 20. One side of the pressure plate 212 is provided with a force-bearing plate 212 and a brush head 211 that can abut against and clean the surface of the wheel. The brush head 211 is provided with several bolt fasteners that slide through the pressure plate 21, which facilitates the replacement of the brush head 211 and reduces the later maintenance cost. One side of the force-bearing plate 212 is provided with several protrusions 213 along the axial direction. The cross-section of the multiple protrusions 213 is semi-circular, and their diameter increases linearly along the extension direction of the force-bearing plate 212. The change in the diameter of the protrusions 213 enables them to generate vibrations of different frequencies and amplitudes when squeezed by the push rod 223.

[0030] On the other side of the pressure plate 21, an elastic reset member 214 is elastically connected to the bracket 20, and the brush head 211 is driven to move towards the wheel by the elastic force. The elastic reset member 214 is one of a compression spring, a tension spring, or a torsion spring; it ensures reliable contact between the brush head 211 and the wheel surface during the cleaning process; at the same time, it provides elastic support for the reset of the pressure plate 21 during the vibration cleaning process, and enhances the vibration frequency and amplitude.

[0031] Follower 22, rotatably mounted on bracket 20 and capable of contacting the wheel, includes a push rod 223 that rotates synchronously with the wheel, and the rotation path of push rod 223 passes through force plate 212; follower 22 includes a roller 220 rotatably mounted on bracket 20, a drive gear 221 is provided on one side of roller 220, a driven gear 222 that meshes with drive gear 221 is rotatably mounted on bracket 20, and push rod 223 is located on the outer edge of one side of driven gear 222; as a power conversion component for "wheel movement - brush head 211 vibration", through contact with the wheel, the rotational motion of the wheel is converted into the reverse periodic rotation of push rod 223, providing a power source for the vibration and impurity removal of brush head 211, realizing an energy-saving design that uses wheel kinetic energy to drive impurity removal, without the need for additional power devices.

[0032] When the push rod 223 of the follower 22 passes the force plate 212 as the wheel rotates, the push rod 223 will first squeeze the force plate 212, causing the brush head 211 to deviate from the wheel, and then contact the protrusions 213 of different diameters in sequence, generating an "intermittent squeezing force" through the diameter gradient difference; this force is transmitted to the pressure plate 21, causing the brush head 211 to generate high-frequency micro-vibration, which can shake off the impurities and dust remaining on the surface of the brush head 211, realizing the autonomous cleaning of the brush head 211, solving the pain point of "impurities accumulating and needing manual cleaning" in traditional cleaning brushes, and significantly improving the continuous cleaning ability of the brush head 211.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
