Description

Technical Field

[0001] This utility model relates to the field of rail vehicle technology, and in particular to a bogie and a rail vehicle. Background Technology

[0002] In recent years, with the rapid development and capacity improvement of urban rail transit networks, some cities have begun to explore utilizing the surplus capacity of rail transit during off-peak hours for express delivery. This not only helps alleviate the freight pressure on urban roads but also improves the resource utilization efficiency of rail transit. However, existing rail vehicles struggle to cope with special environments such as steep gradients, small curve radii, heavy loads, and strong winds during freight transport, limiting their transport capacity and preventing the full realization of the transport capacity advantages of rail transit.

[0003] Therefore, linear motor-driven rail vehicles are adopted to improve their operational capabilities under complex terrain conditions. Compared to traditional rail vehicles, although linear motor-driven rail vehicles have advantages such as strong climbing ability, small turning radius, and low noise, in actual operation, when dealing with extreme environments such as strong winds, low temperatures, and ice and snow, the lack of optimized design for linear motor characteristics in existing bogies leads to insufficient lateral stability in these vehicles, making them prone to derailment accidents and seriously affecting operational safety. Utility Model Content

[0004] The purpose of this utility model is to provide a bogie and rail vehicle in which a first stop assembly is added to the bottom of the axle box. The ends of the two stop plates of the first stop assembly are bent to form an anti-disengagement hook. The anti-disengagement hook abuts against the rail jaw to ensure that the rail vehicle does not derail, thereby improving the running safety of the rail vehicle and solving the technical problem of insufficient running safety of existing rail vehicles due to insufficient lateral stability.

[0005] To achieve the above objectives, this utility model provides a bogie, including a wheelset, an axle box, and at least one set of first stop assemblies fixed to the bottom of the axle box. Each set of first stop assemblies includes two stop plates fixed to opposite sides of the axle box, with the two stop plates located between the two wheel rims of the wheelset. The end of each stop plate is bent to form an anti-disengagement hook, which is used to abut against the rail jaws of the track when the wheel rims disengage from the track.

[0006] In some embodiments, the lateral distance between the stop plate and the wheel rim ranges from 20mm to 200mm; the vertical distance between the lower edge of the stop plate and the lower edge of the wheel rim ranges from 10mm to 130mm.

[0007] In some embodiments, an adjusting shim is provided between the first stop assembly and the axle box, the adjusting shim being used to adjust the vertical height of the first stop assembly.

[0008] In some embodiments, the system further includes a frame and an induction plate fixed between two rails on the track, the induction plate being vertically opposite to a linear motor mounted on the frame; the induction plate is used to provide longitudinal thrust to the vehicle body under the action of the linear motor.

[0009] At least one set of second stop assemblies is fixed on the lower surface of the linear motor. The second stop assembly includes two stop blocks respectively fixed on the lower surface of the linear motor. The sensing plate is located between the two stop blocks, and the two stop blocks are used to prevent the linear motor from deviating laterally from the sensing plate.

[0010] In some embodiments, a vertical gap is formed between the upper surface of the sensing plate and the lower surface of the linear motor; the value of the vertical gap ranges from 9mm to 10mm.

[0011] In some embodiments, the lateral distance between the stop block and the sensing plate ranges from 20mm to 80mm; the lower edge of the stop block is set below the upper surface of the sensing plate, and the vertical distance between the lower edge of the stop block and the upper surface of the sensing plate ranges from 10mm to 200mm.

[0012] In some embodiments, the sensing plate is fixed between two rails by a fixing seat; the fixing seat includes a first support plate, a second support plate and a transverse connecting plate fixed between the first support plate and the second support plate, and both the first support plate and the second support plate are L-shaped structures.

[0013] In some embodiments, the system further includes current collector shoes fixed to both sides of the frame and extending laterally, with elastic stops fixed to the ends of the current collector shoes.

[0014] In some embodiments, a conductive rail is further included, with an elastic stop abutting against the conductive rail vertically.

[0016] Compared to the prior art, this utility model adds a first stop assembly to the bottom of the axle box. Each first stop assembly includes two stop plates located between the two wheel rims of the wheelset. The end of each stop plate is bent to form an anti-disengagement hook. When the wheel rim disengages from the track, the anti-disengagement hook abuts against the rail jaw, allowing the wheel rim to continue running along the track, ensuring that the rail vehicle does not derail, thus preventing derailment, reducing the risk of derailment accidents, and improving the operational safety of the rail vehicle.

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

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

[0030] First, it should be noted that in this text, "horizontal" refers to the width direction parallel to the vehicle body, "vertical" refers to the height direction parallel to the vehicle body, and "longitudinal" refers to the length direction parallel to the vehicle body.

[0031] This utility model discloses a bogie, including a wheelset 1, an axle box 2, and at least one set of first stop assemblies. The axle box 2 is an internal design, located between the two wheel rims 101 of the wheelset 1. By reducing the cantilever length at both ends of the wheelset 1, the width of the bogie is reduced to adapt to narrower tracks. Simultaneously, by enhancing the lateral stiffness of the wheelset 1, curve-passing performance is improved, thus enhancing the overall vehicle's running stability. All first stop assemblies are evenly distributed longitudinally, with each set of first stop assemblies aligned laterally with one set of wheelset 1.

[0032] Each first stop assembly includes two stop plates 3 respectively fixed on two opposite sides of the axle box 2. The two stop plates 3 are located between the two wheel rims 101 of the wheelset 1. One end of each stop plate 3 is fixed to the lower surface of the axle box 2, and the other end is bent to form an anti-disengagement hook 301, which is bent toward the wheelset 1.

[0033] When the wheel rim 101 detaches from the track 4, the anti-derailment hook 301 abuts against the rail jaw 401 of the track 4, allowing the wheel rim 101 to continue running under the track 4, ensuring that the rail vehicle does not derail, thus preventing the rail vehicle from derailing, reducing the risk of derailment accidents, and improving the operational safety of the rail vehicle.

[0034] In a preferred embodiment, the lateral distance between the stop plate 3 and the wheel rim 101 ranges from 20mm to 200mm, preferably 80mm, ensuring that the stop plate 3 and the wheel rim 101 maintain an appropriate lateral distance and preventing the stop plate 3 from affecting the normal operation of the wheel rim 101. The vertical distance between the lower edge of the stop plate 3 and the lower edge of the wheel rim 101 ranges from 10mm to 130mm, preferably 40mm, ensuring that the stop plate 3 and the track 4 maintain an appropriate vertical distance, preventing severe wear from contact between the stop plate 3 and the bolster beam, and thus extending the service life of the stop plate 3.

[0035] In a preferred embodiment, an adjusting shim is provided between the first stop assembly and the axle box 2. The adjusting shim is used to adjust the vertical height of the first stop assembly, compensate for the assembly error between the axle box 2 and the first stop assembly, and help improve the assembly accuracy.

[0036] In a preferred embodiment, the bogie also includes a frame and an induction plate 5 fixed between two rails of the track 4. The induction plate 5 and the linear motor 6 mounted on the frame are arranged vertically opposite each other. The induction plate 5 is used to provide longitudinal thrust to the car body under the action of the linear motor 6, driving the car body to run along the track 4. Specifically, the induction plate 5 cuts the magnetic field lines generated by the linear motor 6, and uses the vertical electromagnetic force between the linear motor 6 and the induction plate 5 to automatically balance the weight of the car body, suppress vertical vibration caused by unevenness of the track 4, and improve ride comfort.

[0037] At least one set of second stop assemblies is fixed to the lower surface of the linear motor 6. The second stop assembly includes two stop blocks 7 respectively fixed to the lower surface of the linear motor 6; all the second stop assemblies are evenly distributed along the longitudinal direction. The sensing plate 5 is located between the two stop blocks 7. The two stop blocks 7 are used to prevent the linear motor 6 from deviating from the sensing plate 5 in the lateral direction, thereby preventing the wheel rim 101 from deviating from the track 4 in the lateral direction, and also achieving anti-derailment, further improving the operational safety.

[0038] In a preferred embodiment, a vertical gap is formed between the upper surface of the sensing plate 5 and the lower surface of the linear motor 6. This gap prevents direct contact between the linear motor 6 and the sensing plate 5, eliminating frictional losses in traditional mechanical transmissions. This reduces maintenance requirements and eliminates vibration and noise caused by friction. The vertical gap ranges from 9mm to 10mm.

[0039] In a preferred embodiment, the lateral distance between the stop block 7 and the sensing plate 5 ranges from 20mm to 80mm, preferably 50mm. This ensures that the stop block 7 and the sensing plate 5 maintain an appropriate lateral distance, preventing both excessively small lateral distances from causing severe wear on both, and excessively large lateral distances from affecting the derailment prevention effect. The lower edge of the stop block 7 is set lower than the upper surface of the sensing plate 5, ensuring a sufficiently large contact area between the stop block 7 and the sensing plate 5. When the vehicle moves laterally, the end of the sensing plate 5 completely abuts against the stop block 7, preventing the stopping effect from being affected by an insufficient contact area. The vertical distance between the lower edge of the stop block 7 and the upper surface of the sensing plate 5 ranges from 10mm to 200mm.

[0040] In a preferred embodiment, the sensing plate 5 is fixed between two rails by a fixing seat 8. The fixing seat 8 includes a first support plate, a second support plate, and a transverse connecting plate fixed between the first and second support plates. Both the first and second support plates are L-shaped, which improves the mechanical strength of the fixing seat 8, ensures stable fixing of the sensing plate, and enables it to withstand greater lateral impacts, thereby improving the reliability of the sensing plate 5. Of course, the structure of the fixing seat 8 is not limited to this.

[0041] As a preferred embodiment, the bogie also includes current collector shoes 9 fixed on both sides of the frame and extending laterally. The ends of the current collector shoes 9 are fixed with elastic blocks 901. When the car body is affected by extreme environments such as strong winds and tends to overturn, the elastic blocks 901 restore elastic deformation to provide the bogie with the opposite lateral load, provide lateral stop for the car body, and can also prevent derailment, further improving operational safety.

[0042] In a preferred embodiment, the bogie also includes a conductive rail 10 for a three-rail current-collecting rail vehicle, with the conductive rail 10 located beside the track 4. An elastic stop 901 abuts against the conductive rail 10 vertically, enabling the current collector shoe 9 to contact the conductive rail 10 to collect electrical energy, while also preventing lateral displacement of the car body, thus preventing derailment. Furthermore, the elastic stop 901 can absorb impact vibrations between the current collector shoe 9 and the conductive rail 10, improving the stability of the car body's operation.

[0043] This utility model also provides a rail vehicle, including the above-mentioned bogie, which has the same beneficial effects.

[0044] 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.

[0045] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
