Description

Technical Field

[0001] This application relates to the field of rail transit technology, and in particular to a guiding device for a rubber-tired and steel-wheeled double-rail vehicle bogie. Background Technology

[0002] Rubber-tired steel-wheeled dual-rail vehicles are based on traditional steel-wheeled and steel-rail vehicles, with the addition of a rubber-tired running system and a rubber-tired guiding system. They have advantages such as strong climbing ability, good traction and braking performance, low noise, and good ride comfort.

[0003] The rubber-tired guide system guides the vehicle's normal movement by having four guide wheels on the bogie press against the guide rails on both sides of the track. The four guide wheels, made of rubber tires, are installed at the four corners of the bogie frame. During normal operation, two guide wheels on each side of the frame press against the guide rail on one side of the track, limiting the lateral movement of the bogie and ensuring the stability of the train.

[0004] However, after prolonged use, the rubber guide wheel will wear down and its diameter will decrease, resulting in a reduction in the compression of the rubber guide wheel on the guide rail. Consequently, the lateral displacement of the bogie relative to the track will increase, leading to a decrease in the lateral stability of the train.

[0005] Currently, existing technologies for addressing guide wheel wear require manual adjustment and compensation of the compression of each guide wheel individually. However, this adjustment process is time-consuming, requires specific work sites, and has an uncertain adjustment cycle, thus causing inconvenience in the maintenance and operation of bogies for rubber-tired and steel-wheeled dual-rail vehicles. Summary of the Invention

[0006] In view of this, the purpose of this application is to provide a guiding device for a rubber-tired steel-wheeled double-rail vehicle bogie, which can automatically adjust and compensate for the compression of the rubber guide wheel on the guide rail, so as to improve the adjustment timeliness after the guide wheel wears out, reduce manual maintenance time, and reduce operating costs.

[0007] To achieve the above objectives, this application provides a guiding device for a rubber-tired and steel-wheeled double-rail vehicle bogie, comprising:

[0008] The frame is a support component of a rectangular frame structure;

[0009] End supports are provided and fixed along the four bottom corners of the frame, and the end supports are inclined toward the corresponding side guide rails.

[0010] A first link is hinged to the end of the end support, and a guide wheel is mounted on the first link, the guide wheel being positioned between the frame and the guide rail;

[0011] A compression spring is provided at the bottom of the frame, and the compression spring drives the guide wheel to press against the guide rail on the corresponding side.

[0012] Preferably, the bottom of the frame is provided with a connector, the compression spring is installed inside the connector, and a support rod is inserted into each end of the connector, the end of the support rod inserted into the connector being in close contact with the end of the compression spring.

[0013] Preferably, the strut includes a head section and a tail section, the head section has a threaded hole at its end, the tail section has a threaded protrusion at its end that mates with the threaded hole, and the head section and the tail section are connected by threads.

[0014] Preferably, the threads at both ends of the connector are opposite in direction to the head section and the tail section.

[0015] Preferably, the head section is inserted into the connector, and the portion of the head section placed inside the connector is fixed with a baffle. The head section is inserted into the connector and can rotate, but cannot detach from the connector. The tail section is provided with a hinge.

[0016] Preferably, the number of connectors is 2, and the connectors are respectively disposed at the head and tail of the frame, with the hinge of the tail section being hinged to the free end of the first connecting rod.

[0017] Preferably, the first connecting rod and the hinge lug are provided with a certain amount of movement.

[0018] Preferably, the number of the connectors is 1, and the connectors are located in the middle of the frame.

[0019] Preferably, the hinge lug has two symmetrically arranged second connecting rods, and the free end of the second connecting rod is hinged to the free end of the first connecting rod on the corresponding side.

[0020] Preferably, the connector is a rectangular cavity structure, the compression spring is installed inside the cavity structure, and the cavity structure has through holes at both ends, through which the support rod is inserted.

[0021] Compared to the aforementioned background technology, the guiding device for the rubber-tired and steel-wheeled double-rail vehicle bogie provided in this application utilizes the elastic potential energy released after the compression spring is compressed. This elastic potential energy is transmitted to the guide wheel via the first connecting rod, enabling the guide wheel to maintain a tendency to move closer to the guide rail. Under this tendency, the worn guide wheel can automatically fill in the gap towards the track under the continuous action of the elastic potential energy provided by the compression spring.

[0022] No manual intervention is required during this process. The guiding device can automatically adjust the lateral distance between the guide wheel and the guide rail to compensate for the wear of the guide wheel, thereby improving the timeliness of adjustment after the guide wheel wears out, reducing manual maintenance time, and lowering operating costs.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" used below are defined based on the accompanying drawings in the instruction manual.

[0031] The guiding device for the rubber-tired and steel-wheeled double-rail vehicle bogie provided in this application mainly includes: a frame 1, an end support 2, a first connecting rod 3, a guide wheel 4, and a compression spring 5.

[0032] Frame 1 is a supporting component of a rectangular frame structure;

[0033] The end supports 2 are arranged and fixed along the four corners of the bottom of the frame 1, and the end supports 2 are inclined towards the corresponding side guide rail 10.

[0034] The first link 3 is hinged to the end of the end support 2. A guide wheel 4 is installed on the first link 3 and the guide wheel 4 is placed between the frame 1 and the guide rail 10.

[0035] Compression spring 5 is installed at the bottom of frame 1, and compression spring 5 drives guide wheel 4 to press against the corresponding side guide rail 10.

[0036] Specifically, the frame 1 is placed between two parallel guide rails 10. The frame 1 is a rectangular frame structure, which facilitates the installation and use between the rails. The rectangular frame structure provides a stable mounting position for other components such as the end supports 2, the first connecting rod 3, the guide wheel 4, and the compression spring 5. At the same time, the rectangular frame structure has high stability and can provide a high level of load for heavy-duty rail vehicles. The frame 1 is divided into a head and a tail section along the rail direction. In the following description, the right end of the frame 1 is the head section, and the left end is the tail section.

[0037] End supports 2 are arranged and fixed along the four corners of the bottom of the frame 1. The end supports 2 are inclined towards the corresponding side guide rail 10. The end supports are arc-shaped and are installed at the ends of the frame 1. The end supports have high strength and provide mounting support for the first connecting rod 3. The end supports are provided with hinge pin holes.

[0038] Optionally, a baffle is installed on the end support 2. The end support 2 is located directly in front of the running wheel and the guide wheel 4. The baffle of the end support 2 serves to sweep away stones and remove obstacles, ensuring the safety of vehicle driving.

[0039] Both ends of the first connecting rod 3 are provided with hinge pin holes. One end of the first connecting rod 3 is hinged to the hinge pin hole of the end support seat by a pin, providing a rotating connection pair for the rotation of the first connecting rod 3. A mounting position for a guide wheel 4 is provided in the middle of the first connecting rod 3. The guide wheel 4 is mounted on the first connecting rod 3. When mounted, the guide wheel 4 should be positioned between the frame 1 and the guide rail 10, with its outer edge positioned outside the traveling wheel. Sufficient space is provided for the guidance of the guide wheel 4, and sufficient space allowance is also provided for the automatic adjustment and compensation of the guide wheel 4.

[0040] Compression spring 5 is set at the bottom of frame 1. Compression spring 5 drives guide wheel 4 to press against the corresponding side guide rail 10. Specifically, when compression spring 5 is compressed, the release of elastic potential energy drives the free end of first link 3 to rotate around its junction position on end support 2. This rotation process drives guide wheel 4 to move towards the corresponding side guide rail 10.

[0041] Meanwhile, after the guide wheel 4 contacts the guide rail 10, the elastic potential energy of the compression spring 5 is not fully released, so that the guide wheel 4 and the guide rail 10 are continuously pressed together, and the guide wheel 4 is automatically adjusted and compensated as the compression spring 5 is continuously released after the guide wheel 4 wears.

[0042] Throughout the automatic adjustment and compensation process, the power source is the elastic potential energy released after the compression spring 5 is compressed. The elastic potential energy is transmitted to the guide wheel 4 through the first connecting rod 3, so that the guide wheel 4 always maintains the tendency to move closer to the guide rail 10. Under this tendency, the worn guide wheel 4 can automatically fill the gap in the direction of the track under the continuous action of the elastic potential energy provided by the compression spring 5.

[0043] This process requires no manual intervention. The guiding device can automatically adjust the lateral distance between the guide wheel 4 and the guide rail 10, compensating for the wear of the guide wheel 4, thereby improving the timeliness of adjustment after wear, reducing manual maintenance time, and lowering operating costs. The guiding device can effectively extend the maintenance cycle of the guide wheel 4, improve vehicle operating efficiency, save maintenance costs, and increase economic benefits.

[0044] Based on any of the above embodiments, the bottom of the frame 1 is provided with a connector 6, the compression spring 5 is installed inside the connector 6, and a support rod 7 is inserted into each end of the connector 6. The end of the support rod 7 inserted into the connector 6 is in close contact with the end of the compression spring 5.

[0045] Specifically, by introducing connector 6, a stable installation space is provided for compression spring 5, ensuring that compression spring 5 will not twist or deform during compression and ensuring the safety of compression spring 5 during use.

[0046] A support rod 7 is inserted into each end of the connector 6. The support rod 7 and the connector 6 are connected by a plug-in method to ensure that the support rod 7 and the connector 6 can rotate. After the end of the support rod 7 is inserted into the connector 6, the compression spring 5 contacts and adheres tightly to the end of the support rod 7 inserted into the connector 6.

[0047] During this process, the elastic potential energy of the compression spring 5 is transmitted to the first connecting rod 3 through the support rod 7, and then to the guide wheel 4 through the first connecting rod 3, so that the guide wheel 4 maintains the tendency to return to its original position.

[0048] Based on any of the above embodiments, the support rod 7 includes a head section 701 and a tail section 702. The end of the head section 701 is provided with a threaded hole, and the end of the tail section 702 is provided with a threaded protrusion that mates with the threaded hole. The head section 701 and the tail section 702 are connected by threads.

[0049] Specifically, the strut 7 is a split type, consisting of a head section 701 and a tail section 702, which are connected by bolts.

[0050] Optionally, the head section 701 and the tail section 702 are connected by a pin and a pin hole.

[0051] Optionally, the head section 701 and the tail section 702 are connected by a slot and a block.

[0052] The threaded connection allows for stepless adjustment of the length of the strut 7. Compared to other detachable methods, the threaded connection offers stronger connectivity and a more convenient adjustment method.

[0053] The head section 701 has a threaded hole at its end, and the tail section 702 has a threaded protrusion at its end corresponding to the threaded hole. The threaded hole and the threaded protrusion should have appropriate length and strength to meet the requirements for adjusting the length of the strut 7, and at the same time meet the requirements for the connection strength after adjustment.

[0054] Based on any of the above embodiments, the thread directions between the head section 701 and the tail section 702 at both ends of the connector 6 are opposite.

[0055] Specifically, the two ends of the connector 6 face the corresponding guide rails 10, so the support rods 7 on the connector 6 drive the guide wheels 4 on the corresponding sides. The head section 701 and the tail section 702 on the support rods 7 at both ends have opposite thread directions, which is to facilitate subsequent manual adjustment of the length of the support rods 7. When adjusting the support rods 7 on both sides, it is only necessary to rotate the head section 701 to one side, without having to distinguish the position of the support rods 7. This method reduces the convenience and difficulty of adjustment for workers and can effectively avoid errors by novice workers.

[0056] Based on any of the above embodiments, the head section 701 is inserted into the connector 6, and the part of the head section 701 placed in the connector 6 is fixed with a baffle 8. The head section 701 is inserted into the connector 6 and can rotate, but cannot be separated from the connector 6. The tail section 702 is provided with a hinge 9.

[0057] Specifically, a retaining plate 8 is fixed to the end of the head section 701 of the strut 7 that is inserted into the connector 6. The strut 7 has a cylindrical structure. After the strut 7 is inserted into the connector 6, the retaining plate 8, which has a larger diameter, limits the head section 701 of the strut 7 within the connector 6, thus connecting the head section 701 of the strut 7 to the connector 6. The head section 701 cannot be separated from the connector 6 after connection, while also allowing the head section 701 of the strut 7 to rotate on the connector 6. The tail of the strut 7 is provided with a hinge lug 9, which provides an installation position for the strut 7 to be installed with other support and drive components, improving the ease of installation and ensuring connection strength.

[0058] Please refer to Figure 1Based on any of the above embodiments, the number of connectors 6 is 2. Connectors 6 are respectively installed at the head and tail of the frame 1. The hinge 9 of the tail section 702 is hinged to the free end of the first connecting rod 3. Connectors 6 can slide at the bottom of the frame 1 and rotate themselves, which facilitates the installation of the support rod 7.

[0059] Specifically, the bottom of the frame 1 is provided with two connecting parts 6, which makes the two sets of guide wheels 4 at the head and tail of the frame 1 adopt a split drive method. In this way, the elastic potential energy that the compression spring 5 needs to release is relatively small. At the same time, the separate drive of the guide wheels 4 at the head hinge 9 and tail of the frame 1 allows the guide wheels 4 at the head and tail of the frame 1 to provide different automatic adjustment capabilities when the wear is inconsistent, so that the adjustment capability is always consistent with the guide wheels 4 when the wear is consistent.

[0060] Based on any of the above embodiments, the first connecting rod 3 and the hinge lug 9 are provided with a movement allowance at the hinge position.

[0061] When the strut 7 extends outward along the end hole of the connector 6, the first connecting rod 3 rotates about its hinged position on the end support 2. During this rotation, the hinged position between the first connecting rod 3 and the hinge lug 9 will generate a displacement to accommodate the rotation. Therefore, sufficient displacement space should be provided for this displacement.

[0062] Optionally, the first connecting rod 3 and the hinge lug 9 are hinged by a pin and a pin hole. The pin is slidably mounted on the first connecting rod 3, and the end of the pin is rotatably connected to the hinge lug 9.

[0063] Optionally, the first connecting rod 3 and the hinge lug 9 are hinged by a pin and a pin hole. The pin is fixedly installed on the first connecting rod 3, and the pin hole on the hinge lug 9 is strip-shaped, providing the pin with a movement allowance.

[0064] Please refer to Figure 2 Based on any of the above embodiments, the number of connectors 6 is 1, and connectors 6 are located in the middle of the frame 1.

[0065] When the connector 6 is a single piece, one connector 6 needs to provide support and drive for the four guide wheels 4. Therefore, the connector 6 should be located in the middle of the frame 1 to provide equivalent support and drive for the four guide wheels 4.

[0066] A single connector 6 provides drive and support, which can effectively reduce the number of connectors 6. The four guide wheels 4 can be adjusted synchronously, reducing manual adjustment operations by half and making manual operation simpler.

[0067] Based on any of the above embodiments, two symmetrically arranged second connecting rods 11 are connected to the hinge lug 9, and the free end of the second connecting rod 11 is hinged to the free end of the first connecting rod 3 on the corresponding side.

[0068] To facilitate the driving of four guide wheels 4 by a single connector 6, two second links 11 should be symmetrically hinged to each hinge lug 9. The free end of the second link 11 is hinged to the free end of the first link 3 on the corresponding side. By introducing the second links 11, each strut 7 can simultaneously drive two guide wheels 4 on the side of a single guide rail 10, thereby improving the utilization rate of the connector 6 of the strut 7.

[0069] Based on any of the above embodiments, the connector 6 is a rectangular cavity structure, the compression spring 5 is installed inside the cavity structure, and the two ends of the cavity structure are provided with through holes, through which the support rod 7 is inserted.

[0070] To facilitate the installation of the strut 7 and the compression spring 5, the connector 6 has a rectangular cavity structure. Under this structure, the reset and compression of the compression spring 5 are limited by the outer wall of the rectangular structure, preventing the compression spring 5 from bending and failing.

[0071] The connector 6 has through holes at both ends to provide space for the installation of the support rod 7. The support rod 7 is inserted through the through holes, and the diameter of the support rod 7 matches the diameter of the through holes. The support rod 7 is slidably installed on the through holes, and the sliding connection prevents the support rod 7 from shaking. The inner diameter of the connector 6 is larger than the diameter of the retaining plate 8, and the diameter of the retaining plate 8 is larger than the diameter of the support rod 7. The retaining plate 8 provides a larger support surface for the support rod 7 and the compression spring 5 compared to the support rod 7 directly contacting the compression spring 5.

[0072] Taking the example of two connectors 6 on the frame 1, the working process of this application is described as follows:

[0073] The right end of the frame 1 is the head, and the left end is the tail. Connector 6 is located at the bottom of the frame 1, with one connector 6 installed at the middle position of the head and tail of the frame 1. Connector 6 is a rectangular frame structure, and compression spring 5 is installed inside connector 6. The rectangular frame structure provides limit and support for compression spring 5, ensuring that compression spring 5 will not bend or deform.

[0074] Each connector 6 is fitted with two support rods 7. The head section 701 of the support rod 7 is inserted through the through hole, and the support rod 7 is slidably installed with the through hole to prevent radial wobbling of the support rod 7. The end of the support rod 7 head section 701 placed inside the connector 6 is fixed by a retaining plate 8. The retaining plate 8 prevents the support rod 7 from detaching from the connector, while providing a larger contact area for the compression spring 5 and ensuring the rotational adjustment of the support rod 7. The compression spring 5 contacts the retaining plate 8 but is not fixed.

[0075] The head section 701 and the tail section 702 of the strut 7 are connected by a threaded hole and a threaded protrusion. The threaded connection provides a stepless adjustment method and ensures the stability of the connection.

[0076] The hinge lug 9 on the tail section 702 of the strut 7 is hinged to the first connecting rod 3. The hinge lug 9 and the first connecting rod 3 are hinged at a position that provides displacement margin at the hinge point, ensuring that the first connecting rod 3 can always rotate around its end support when the strut 7 is extended or retracted, thereby ensuring the drive of the guide wheel 4. The inclined end support provides a reasonable installation position for the guide wheel 4.

[0077] The guide wheel 4 contacts the guide rail 10. By screwing the head section 701 on the support rod 7, the head section 701 rotates within the connector 6, thereby extending the entire support rod 7. The extended support rod 7 compresses the compression spring 5. After the compression spring 5 is compressed, the elastic potential energy is released, driving the support rod 7 to swing the first connecting rod 3 outward, thereby driving the guide wheel 4 to press against the guide rail 10, thus completing the guiding function of the frame 1.

[0078] When the guide wheel 4 wears out, the compression spring 5 continues to extend and retract, and the guide wheel 4 always maintains pressure contact with the guide rail 10, thereby achieving automatic compensation and adjustment for wear.

[0079] When the guide wheel 4 wears down to a certain extent, the worker can adjust the length of the support rod 7 to achieve secondary compression of the compression spring 5. The head section 701 and tail section 702 of the support rod 7 at both ends of the connector 6 have opposite thread directions. When adjusting the support rod 7 on both sides, the extension or contraction of the support rod 7 at both ends can be satisfied by turning in one direction.

[0080] When disassembly is required, the entire support rod 7 can be retracted by turning the head section 701 of the support rod 7, thereby separating the guide wheel 4 from the guide rail 10. In this separated state, the entire device can be disassembled and replaced.

[0081] Taking a connector 6 installed on the frame 1 as an example, the working process of this application is described as follows:

[0082] The right end of frame 1 is the head, and the left end is the tail. Connector 6 is installed in the middle of the bottom of frame 1. Connector 6 is a rectangular frame structure. Compression spring 5 is installed inside connector 6. The rectangular frame structure provides limit and support for compression spring 5, ensuring that compression spring 5 will not bend or deform.

[0083] Two support rods 7 are fitted onto the connector 6. The head section 701 of the support rod 7 is inserted through the through hole, and the support rod 7 is slidably installed with the through hole to prevent radial wobbling of the support rod 7. The end of the support rod 7 head section 701 placed inside the connector 6 is fixed by a retaining plate 8. The retaining plate 8 prevents the support rod 7 from detaching from the connector, while providing a larger contact area for the compression spring 5 and ensuring the rotational adjustment of the support rod 7. The compression spring 5 contacts the retaining plate 8 but is not fixed.

[0084] The head section 701 and the tail section 702 of the strut 7 are connected by a threaded hole and a threaded protrusion. The threaded connection provides a stepless adjustment method and ensures the stability of the connection.

[0085] The hinge lug 9 on the tail section 702 of the strut 7 is hinged to two symmetrically arranged second connecting rods. The second connecting rod 11 is hinged to the corresponding first connecting rod 3. The strut 7 drives the guide wheel 4 through the second connecting rod 11 and the first connecting rod 3. The inclined end support provides a reasonable installation position for the guide wheel 4.

[0086] The guide wheel 4 contacts the guide rail 10. By screwing the head section 701 on the support rod 7, the head section 701 rotates within the connector 6, thus extending the entire support rod 7. The extended support rod 7 compresses the compression spring 5. After the compression spring 5 is compressed, the elastic potential energy is released, driving the support rod 7 to move the second connecting rod 11. The second connecting rod 11 drives the first connecting rod 3 to swing outward, thereby driving the guide wheel 4 to press against the guide rail 10, completing the guiding function of the frame 1.

[0087] When the guide wheel 4 wears out, the compression spring 5 continues to extend and retract, and the guide wheel 4 always maintains pressure contact with the guide rail 10, thereby achieving automatic compensation and adjustment for wear.

[0088] When the guide wheel 4 wears down to a certain extent, the worker can adjust the length of the support rod 7 to achieve secondary compression of the compression spring 5. The head section 701 and tail section 702 of the support rod 7 at both ends of the connector 6 have opposite thread directions. When adjusting the support rod 7 on both sides, the extension or contraction of the support rod 7 at both ends can be satisfied by turning in one direction.

[0089] When disassembly is required, the entire support rod 7 can be retracted by turning the head section 701 of the support rod 7, thereby separating the guide wheel 4 from the guide rail 10. In this separated state, the entire device can be disassembled and replaced.

[0090] The guiding device of the present invention can automatically adjust the lateral distance between the guide wheel 4 and the guide rail 10, compensate for the wear of the guide wheel 4, improve the adjustment timeliness after the guide wheel 4 wears out, reduce manual maintenance time, and reduce operating costs.

[0091] In addition to automatically adjusting and compensating for the wear of the guide wheel 4, the guide device can also manually adjust and compensate for the wear of both guide wheels 4 on the same end simultaneously during maintenance and repair, or manually adjust and compensate for the wear of a single guide wheel 4. The adjustment methods are diverse and can meet the specific requirements of actual maintenance and use, making it convenient and practical.

[0092] The guide device can effectively extend the maintenance cycle of the guide wheel 4, improve the vehicle's operating efficiency, save maintenance costs, and improve economic benefits.

[0093] The guide device is located at the bottom of the bogie, and the end support 2 is located directly in front of the running wheel and the guide wheel 4. The baffle of the end support 2 can play the function of sweeping away stones and removing obstacles to ensure the driving safety of the vehicle.

[0094] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the solution and core ideas of this application.
