Description

Technical Field

[0001] This invention relates to the field of suspended train technology, and particularly to a vertical base and bogie. Background Technology

[0002] In recent years, suspended rail transit has emerged as a new type of transportation system due to its advantages such as low investment, small land occupation, independent right-of-way, high safety, strong adaptability, and flexible route selection. In the actual use of the vertical base of the bogie, air springs are usually used to flexibly connect the bogie support beam and the train. On the one hand, the air spring can reduce the vibration transmitted to the train through the vertical swing of the support beam, and on the other hand, it can keep the train body in a horizontal state by inflating the air spring. In the actual use of the bogie, the support beam not only applies vertical tension / compression to the air spring, but also applies horizontal force to the air spring when the support beam swings along the horizontal plane.

[0003] In related technologies, in order for the air spring to effectively adapt to the horizontal sway of the bogie, the extensibility of the air spring itself is usually used to adapt to the horizontal force on the air spring. Therefore, it is necessary to ensure that the volume of the air spring is large enough (the larger the volume, the better the extensibility). However, due to the limited space of the bogie, the volume of the air spring should not be too large, which causes the air spring to be unable to adapt to the lateral sway of the bogie. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a vertical base that does not require changing the volume of the damping spring and can accommodate the horizontal swing of the support beam.

[0005] The present invention also proposes a bogie having the above-mentioned vertical base.

[0006] A vertical base according to a first aspect of the present invention comprises:

[0007] Vibration damping springs are used to provide vibration damping in the vertical direction.

[0008] The lower seat is located below the damping spring and is used to connect to the upper part of the support beam;

[0009] The upper seat is connected to the damping spring and is located between the lower seat and the damping spring. The upper seat and the lower seat are fixed relative to each other in the vertical direction, and the upper seat is slidably connected to the lower seat in the horizontal direction.

[0010] The vertical base according to the embodiments of the present invention has at least the following beneficial effects: In the embodiments of the present invention, the damping spring is connected to the upper base and the lower base is connected to the support beam. The upper base and the lower base can slide relative to each other in the horizontal direction. When the support beam swings in the horizontal direction, the upper base and the lower base slide relative to each other, causing the damping spring to be displaced relative to the support beam in the horizontal direction. This displacement can compensate for the insufficient extensibility of the damping spring due to volume limitations. In this way, the damping spring can adapt to the horizontal swing of the support beam without increasing its volume, thus reducing the cost of using the damping spring.

[0011] According to some embodiments of the present invention, the vertical base includes a connecting rod and a hanger. The hanger includes a first connecting part and two second connecting parts. The two second connecting parts are respectively located on opposite sides of the first connecting part. One end of the second connecting part is connected to the first connecting part, and the other end is used to connect to the train. The first connecting part is connected above the damping spring. The opposite ends of the connecting rod are respectively ball-jointed to the second connecting part and the upper seat.

[0012] According to some embodiments of the present invention, the upper seat is provided with a first groove on the side facing the lower seat, and the lower seat is provided with a protrusion on the side facing the upper seat. At least a portion of the protrusion is accommodated in the first groove. In the horizontal direction, the protrusion is slidably connected to the first groove. In the vertical direction, the bottom of the first groove is wider than the opening of the first groove, and the top width of the protrusion accommodated in the first groove is greater than the bottom width, so that the outer surface of the protrusion and the groove wall of the first groove abut against each other in the vertical direction.

[0013] Alternatively, the upper seat has a protrusion on the side facing the lower seat, and the lower seat has a first groove on the side facing the upper seat. At least a portion of the protrusion is accommodated in the first groove. Both the groove and the protrusion extend along a first direction. In the horizontal direction, the protrusion is slidably connected to the first groove. In the vertical direction, the bottom of the first groove is wider than the opening of the first groove, and the bottom width of the protrusion accommodated in the first groove is greater than the top width, so that the outer surface of the protrusion and the groove wall of the first groove abut against each other in the vertical direction.

[0014] The train is capable of traveling in the first direction.

[0015] According to some embodiments of the present invention, the bottom width of the first groove is greater than the top width of the protrusion.

[0016] According to some embodiments of the present invention, the vertical base includes a flexible member that is received within the first groove and at least covers a portion of the protrusion.

[0017] According to some embodiments of the present invention, the first groove and the protrusion extend along the first direction.

[0018] According to some embodiments of the present invention, the sidewall of the first groove is an arc surface with the axis of the support beam swinging relative to the train in the horizontal plane as the center and the distance between the sidewall of the first groove and the axis of the support beam swinging relative to the train as the radius.

[0019] According to some embodiments of the present invention, the top wall of the protrusion is provided with a second groove, and along the extending direction of the protrusion, the second groove has two opposing sidewalls. The vertical base includes a limiting member, the limiting member is connected to the bottom wall of the first groove, and a portion of the limiting member is accommodated in the second groove.

[0020] Alternatively, the bottom wall of the first groove is provided with a second groove, and along the extending direction of the first groove, the second groove has two opposing sidewalls. The vertical base includes a limiting member, which is connected to the top wall of the protrusion, and part of the limiting member is accommodated in the second groove.

[0021] The limiting member is movable within the second groove along the extending direction of the protrusion; along the extending direction of the protrusion, the two opposite sidewalls of the second groove are used to limit the moving distance of the limiting member.

[0022] According to some embodiments of the present invention, the vertical base includes two blocking members spaced apart in a horizontal direction, the blocking members being connected to the lower base, and the two blocking members being able to abut against the upper base respectively to limit the relative movement of the upper base and the lower base;

[0023] Alternatively, the blocking member is connected to the upper seat, and the two blocking members can respectively abut against the lower seat to restrict the relative movement of the upper seat and the lower seat.

[0024] According to a second aspect embodiment of the present invention, a bogie includes a drive mechanism, the support beam, and a plurality of the aforementioned vertical bases. The support beam is connected to the vertical bases, the drive mechanism is connected to the support beam, and the vertical bases are used to connect the train. The drive mechanism is used to drive the support beam, the vertical bases, and the train to travel along a first direction and along a second direction, wherein two of the vertical bases are connected to opposite ends of the support beam; the second direction is perpendicular to the first direction and parallel to the horizontal plane.

[0025] The bogie according to the embodiments of the present invention has at least the following beneficial effects: since the vibration damping springs that can adapt to the horizontal swing of the support beam without increasing the volume are used in this embodiment, the cost of the bogie is reduced, and the service life of the vertical base is extended, thereby making the vertical base less prone to failure in actual use. Applying it to the bogie of this embodiment greatly improves the safety of the bogie.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0053] An embodiment of the first aspect of the present invention provides a vertical base 10 for connecting a train 900 and a support beam 800 on a bogie, wherein the support beam 800 is capable of swinging relative to the train 900 in both vertical and horizontal directions, with reference to... Figure 1 , Figure 2 and Figure 3 The vertical base 10 includes a damping spring 100, a lower base 300, and an upper base 200, for providing damping in the vertical direction; the lower base 300 is located below the damping spring 100 and is used to connect to the upper part of the support beam 800; the upper base 200 is connected to the damping spring 100 and is located between the lower base 300 and the damping spring 100. The upper base 200 and the lower base 300 are fixed relative to each other in the vertical direction, and the upper base 200 is slidably connected to the lower base 300 in the horizontal direction.

[0054] It should be noted that in existing vertical bases 10, air springs are typically used to adjust the vertical positional relationship between the train 900 and the support beam 800. The working principle of the air spring (which is also the main function of the damping spring 100 in this invention) is as follows: During the operation of the train 900, when the support beam 800 swings significantly in the vertical direction, the air spring... Figure 3 In the second direction, the two sides of the supporting beam 800 are uneven, with one side higher than the other. The air spring on the higher side is in a contracted state. Inflating the contracted air spring causes it to return to its original position, restoring the supporting beam 800 to a horizontal state. However, during train 900 operation, the supporting beam 800 also has a horizontal swinging motion. Because air springs are inherently extensible, existing technology directly utilizes the extensibility of the air spring to accommodate the horizontal swinging of the supporting beam 800. This requires a large air spring to meet the extensibility requirement, but the bogie space is limited, so only a smaller air spring can be selected. Consequently, the extensibility of the air spring cannot adequately adapt to the horizontal swinging of the supporting beam 800.

[0055] In this embodiment of the invention, the damping spring 100 is connected to the upper seat 200, and the lower seat 300 is connected to the support beam 800. The upper seat 200 and the lower seat 300 can slide relative to each other in the horizontal direction. When the support beam 800 swings in the horizontal direction, the upper seat 200 and the lower seat 300 slide relative to each other, causing the damping spring 100 to be displaced relative to the support beam 800 in the horizontal direction. This displacement can compensate for the insufficient extensibility of the damping spring 100 due to its volume limitation. In this way, the damping spring 100 can adapt to the horizontal swing of the support beam 800 without increasing its volume, thus reducing the cost of using the damping spring 100.

[0056] Furthermore, during train operation, the horizontal sway of the support beam 800 is relatively frequent. Existing technologies directly utilize the extensibility of the air spring itself to adapt to the horizontal sway of the support beam 800, which accelerates the failure rate of the air spring's extensibility. In the embodiments of the present invention, by setting the upper seat 200 and the lower seat 300 to slide relative to each other, the horizontal deformation amplitude and number of deformations of the damping spring 100 can be reduced, thereby improving the service life of the damping spring 100.

[0057] Furthermore, when the support beam 800 swings vertically, the damping spring 100 is subjected to the vertical force applied by the support beam 800, causing the damping spring 100 to deform vertically. The damping spring 100 then begins to reset and applies a reaction force to the support beam 800, thereby reducing the vertical swing of the support beam 800.

[0058] Understandably, the support beam 800 and the damping spring 100 are fixed relative to each other in the vertical direction, so that the damping spring 100 can operate normally in the vertical direction.

[0059] Since the damping spring 100 is not limited by size, it has a wide range of selection options, which helps to reduce production costs. The damping spring 100 can be selected as an air spring, rubber spring, helical steel spring, etc.

[0060] In some embodiments, reference Figure 1 , Figure 2 and Figure 3 The vertical base 10 includes a connecting rod 400 and a hanger 500. The hanger 500 includes a first connecting part 510 and two second connecting parts 520. The two second connecting parts 520 are located on opposite sides of the first connecting part 510. One end of the second connecting part 520 is connected to the first connecting part 510, and the other end is used to connect to the train 900. The first connecting part 510 is connected above the damping spring 100. The opposite ends of the connecting rod 400 are ball-jointed to the second connecting part 520 and the upper seat 200, respectively.

[0061] When the upper seat 200 and the lower seat 300 rotate relative to each other, the connecting rod 400 is used to pull the upper seat 200 so that the upper seat 200 can remain vertical, thus avoiding the problem of horizontal displacement of the damping spring 100 caused by relative friction between the upper seat 200 and the lower seat 300 when they rotate relative to each other.

[0062] Understandably, during the vertical swing of the support beam 800, the ball joint connection between the connecting rod 400 and the second connecting part 520 can adapt to the swing of the support beam 800, and, referring to Figure 1 During the vertical swing of the support beam 800, it is inevitable that the support beam 800 will move slightly in the second direction. The ball joint connection between the connecting rod 400 and the upper seat 200 can adapt to the slight movement of the support beam 800 in the second direction. Overall, the ball joint connection between the connecting rod 400 and the second connecting part 520 and the upper seat 200 allows the upper seat 200 to fully adapt to the swing of the support beam 800 in all directions.

[0063] In some embodiments, the upper seat 200 is provided with a first groove 210 on the side facing the lower seat 300, and the lower seat 300 is provided with a protrusion 310 on the side facing the upper seat 200. At least a portion of the protrusion 310 is accommodated in the first groove 210. In the horizontal direction, the protrusion 310 is slidably connected to the first groove 210. In the vertical direction, the bottom of the first groove 210 is wider than the opening of the first groove 210, and the top width of the protrusion 310 accommodated in the first groove 210 is larger than the bottom width, so that the outer surface of the protrusion 310 and the groove wall of the first groove 210 abut against each other in the vertical direction. Alternatively, the upper seat 200 has a protrusion 310 on the side facing the lower seat 300, and the lower seat 300 has a first groove 210 on the side facing the upper seat 200. At least part of the protrusion 310 is accommodated in the first groove 210. Both the groove and the protrusion 310 extend along a first direction. In the horizontal direction, the protrusion 310 is slidably connected to the first groove 210. In the vertical direction, the bottom of the first groove 210 is wider than the opening of the first groove 210, and the bottom width of the protrusion 310 accommodated in the first groove 210 is greater than its top width, so that the outer surface of the protrusion 310 and the groove wall of the first groove 210 abut against each other in the vertical direction. The train 900 travels along the first direction.

[0064] In this embodiment, the upper seat 200 is provided with a first groove 210 and the lower seat 300 is provided with a protrusion 310, as shown in the following example. Figure 1 , Figure 2 , Figure 6 and Figure 7Specifically, in this embodiment, the first groove 210 is a dovetail groove structure, and the protrusion 310 can slide relative to the upper seat 200 in the extension direction of the first groove 210, thereby realizing the relative sliding of the lower seat 300 and the upper seat 200 in the horizontal direction; in addition, in the vertical direction, the groove wall of the first groove 210 abuts against the outer surface of the protrusion 310, thereby fixing the upper seat 200 and the lower seat 300 relative to each other in the vertical direction.

[0065] As a further improvement to the previous embodiment, refer to Figure 4 or Figure 5 The bottom width of the first groove 210 is greater than the top width of the protrusion 310. Since the bottom width of the first groove 210 is greater than the top width of the protrusion 310, a certain gap is left between the protrusion 310 and the first groove 210 after the protrusion 310 is accommodated, thereby reducing the friction between the outer surface of the protrusion 310 and the groove wall of the first groove 210.

[0066] Furthermore, in some embodiments, reference is made to... Figure 5 In this embodiment, the vertical base 10 includes a flexible member 600, which is housed in the first groove 210 and at least covers a portion of the protrusion 310. It can buffer the hard impact exerted on the upper seat 200 by the support beam 800 during the swinging process.

[0067] In some embodiments, reference Figure 6 and Figure 7 The first groove 210 and the protrusion 310 extend along the first direction (according to...). Figure 7 As can be seen from the fact that the protrusion 310 extends along the first direction, when the support beam 800 swings in the horizontal direction, the groove wall of the first groove 210 and the protrusion 310 can slide relative to each other in the first direction, thereby reducing the stretching of the damping spring 100 in the horizontal direction and reducing the rate of failure of the flexibility of the flexible part 600; in addition, the fact that the first groove 210 and the protrusion 310 extend in the first direction can be easily manufactured and reduce the processing difficulty.

[0068] As another implementation of the previous embodiment, in some embodiments, reference is made to... Figure 3 and Figure 8 The sidewall of the first groove 210 is an arc surface with the axis of the support beam 800 swinging relative to the train 900 in the horizontal plane as the center and the distance between the sidewall of the first groove 210 and the axis of the support beam 800 swinging relative to the train 900 as the radius.

[0069] Therefore, in this embodiment, the first groove 210 is set to be consistent with the radius of rotation of the support beam 800. The consistency of the rotation center can overcome the defect that the movement trajectory of the first groove 210 and the protrusion 310 are inconsistent, so that the sliding path of the upper seat 200 relative to the lower seat 300 can be effectively matched with the swing trajectory of the support beam 800, thereby maximizing the reduction of the lateral and longitudinal deformation of the damping spring 100 caused by the horizontal swing of the support beam 800.

[0070] In some embodiments, the top wall of the protrusion 310 is provided with a second groove 311. Along the extending direction of the protrusion 310, the second groove 311 has two opposing sidewalls. The vertical base 10 includes a limiting member 211, which is connected to the bottom wall of the first groove 210, and a portion of the limiting member 211 is accommodated in the second groove 311. Alternatively, the bottom wall of the first groove 210 is provided with a second groove 311. Along the extending direction of the first groove 210, the second groove 311 has two opposing sidewalls. The vertical base 10 includes a limiting member 211, which is connected to the top wall of the protrusion 310, and a portion of the limiting member 211 is accommodated in the second groove 311. The limiting member 211 is movable within the second groove 311 along the extending direction of the protrusion 310. Along the extending direction of the protrusion 310, the two opposing sidewalls of the second groove 311 are used to limit the moving distance of the limiting member 211.

[0071] In this embodiment, the top wall of the protrusion 310 is provided with a second groove 311, and the limiting member 211 is connected to the bottom wall of the first groove 210, as an example. Figure 2 , Figure 6 and Figure 7 When the upper seat 200 slides relative to the lower seat 300 and the limiting member 211 abuts against one of the side walls of the second groove 311, the side wall of the second groove 311 will prevent the upper seat 200 and the lower seat 300 from continuing to slide relative to each other in the original direction, thereby limiting the swing amplitude of the lower seat 300 in the horizontal direction.

[0072] As another implementation of the previous embodiment, in some embodiments, reference is made to... Figure 9 The vertical base 10 includes two blocking members 700 spaced apart in the horizontal direction. The blocking members 700 are connected to the lower base 300. The two blocking members 700 can respectively abut against the upper base 200 to limit the relative movement of the upper base 200 and the lower base 300; or, the blocking members 700 are connected to the upper base 200. The two blocking members 700 can respectively abut against the lower base 300 to limit the relative movement of the upper base 200 and the lower base 300.

[0073] By connecting two horizontally spaced blocking members 700 to the upper seat 200, when the lower seat 300 swings horizontally along with the support beam 800, one of the blocking members 700 abuts against the lower seat 300, preventing the lower seat 300 from continuing to swing in the original swing direction, thereby limiting the swing amplitude of the lower seat 300 in the horizontal direction; or, by connecting two horizontally spaced blocking members 700 to the lower seat 300, when the lower seat 300 swings horizontally along with the support beam 800, one of the blocking members 700 abuts against the upper seat 200, preventing the lower seat 300 from continuing to swing in the original swing direction, thereby limiting the swing amplitude of the lower seat 300 in the horizontal direction.

[0074] The present invention also proposes a bogie according to a second aspect embodiment, with reference to Figure 3 The bogie includes a drive mechanism 1000, a support beam 800, and multiple vertical bases 10. The support beam 800 is connected to the vertical bases 10, and the drive mechanism 1000 is connected to the support beam 800. The vertical bases 10 are used to connect to the train 900. The drive mechanism 1000 drives the support beam 800, the vertical bases 10, and the train 900 to travel along a first direction and a second direction, wherein two vertical bases 10 are connected to opposite ends of the support beam 800; the second direction is perpendicular to the first direction and parallel to the horizontal plane. Because this embodiment uses a damping spring 100 that can accommodate the horizontal sway of the support beam 800 without increasing its size, the cost of the bogie is reduced, and the service life of the vertical bases 10 is extended, making the vertical bases 10 less prone to failure during actual use. Applying them to the bogie of this embodiment greatly improves the safety of the bogie.

[0075] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
