Detailed Implementation

[0020] In addition to the problems mentioned in the background technology, existing integral cast mandrel assemblies also have the problem that the mandrel is prone to cracking defects under heavy loads, which endangers the entire base.

[0021] The core of this application is to disclose a center plate assembly to reduce the weight of the center plate assembly and achieve a lightweight design of the center plate assembly.

[0022] Another key aspect of this application is the disclosure of a convertible that includes the aforementioned center plate assembly.

[0023] 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.

[0024] like Figure 1 and Figure 2 As shown in the embodiment of this application, a center plate assembly is disclosed, including a center plate seat 10 and an upper center plate 20. The center plate seat 10 and the upper center plate 20 are separate structures, that is, they are two independent parts. They are assembled to form a center plate assembly. The center plate seat 10 is disposed on the center beam 30 of the underframe of the open wagon, and the upper center plate 20 is a forging. The upper center plate 20 is connected to the center plate seat 10.

[0025] In some specific embodiments, the weight of the upper center plate 20 formed by forging is only 45 kg, while the existing integrally cast center plate assembly weighs about 200 kg. The center plate assembly formed by combining the upper center plate 20 and the center plate seat 10 weighs no more than 60 kg. It can be seen that the center plate assembly disclosed in this application can significantly reduce the weight of the center plate assembly and achieve the characteristics of lightweighting. Moreover, the forging process is green and environmentally friendly compared to the casting process, which can reduce environmental pollution.

[0026] The center plate assembly disclosed in this application has a split structure for the center plate base 10 and the upper center plate 20. The upper center plate 20 is a forging and is connected to the center plate base 10. Compared with the existing center plate assembly where the upper center plate 20 and the center plate base 10 are integrally cast, this design can reduce the weight of the center plate assembly and achieve a lightweight design. Furthermore, the upper center plate 20 formed by forging has higher strength and is easier to install and replace. On the other hand, the split structure of the center plate base 10 and the upper center plate 20 can improve the situation where the upper center plate 20 is prone to cracking defects under heavy loads, which could endanger the center plate base 10.

[0027] In some specific embodiments, such as Figure 1 and Figure 2 As shown, specifically, the center plate holder 10 includes a center plate partition 11 and a center plate holder body 12. The center plate partition 11 is connected to the center plate holder body 12. Preferably, there are two center plate partitions 11 arranged opposite to each other, and a receiving space is formed between the oppositely arranged center plate partitions 11 to accommodate the upper center plate 20.

[0028] In some specific embodiments, such as Figure 1 As shown, the middle beam 30 includes a lower cover plate 31 and a web plate 32, with the web plates 32 arranged on opposite sides of the lower cover plate 31. The core plate seat body 12 is a welded structural component formed by assembly welding, including a first component 121 and a second component 122 connected by welding. The first component 121 is connected to the lower cover plate 31 and the web plate 32, respectively, and the second component 122 is disposed between the first component 121 and the core plate partition 11; each core plate partition 11 is connected to the lower cover plate 31 and the web plate 32, respectively.

[0029] Preferably, the first component 121 is a vertical plate extending along the height direction of the vehicle body on the lower cover plate 31 of the middle beam, and the second component 122 is a horizontal plate extending along the length direction of the vehicle body. The center plate seat 10 can distribute the load of the upper center plate 20 to the lower cover plate 31 and the web plate 32 of the middle beam, thereby reducing stress concentration in the upper center plate 20. The center plate partition 11 is welded to the lower cover plate 31 and the web plate 32 of the middle beam, respectively, and the center plate partition 11 can provide support for the upper center plate 20 to transfer the load upward. Preferably, the first component 121 is welded to the lower cover plate 31 and the web plate 32 of the middle beam, respectively, and the second component 122 is welded to the first component 121, the center plate partition 11, and the web plate 32 of the middle beam, respectively.

[0030] In some specific embodiments, such as Figure 1 As shown, the second component 122 comprises multiple components arranged in parallel, each of which is connected to the web of the central beam 32. The arrangement of multiple second components 122 can improve the structural strength and stiffness of the center plate seat 10, while also distributing and optimizing load transfer.

[0031] In some specific embodiments, in order to provide multiple force transmission paths, such as Figure 2 As shown, the first component 121 includes at least two that are arranged opposite each other, and a plurality of second components 122 are arranged between each first component 121 and the disc diaphragm 11. Figure 2 The first component 121 shown includes two components arranged opposite each other, and the second component 122 includes two components arranged vertically in parallel. It should be noted that the figures are merely examples and should not be taken as limitations.

[0032] In some specific embodiments, such as Figure 1 and Figure 2 As shown, along the vehicle's direction of travel, the first component 121 and the second component 122 are disposed on the front side of the upper center plate 20. Since the load on the front side of the upper center plate 20 is greater than the load on the rear side, the first component 121 and the second component 122 are preferably disposed on the front side of the upper center plate 20 to distribute and optimize the load. Of course, in other specific embodiments, the first component 121 and the second component 122 can also be disposed on the rear side of the upper center plate 20 to distribute and optimize the load.

[0033] In some specific embodiments, the upper center plate 20 and the center plate seat 10 can be connected by a detachable connection or by a non-detachable connection. Preferably, the upper center plate 20 and the center plate seat 10 are welded together to ensure the firmness and reliability of the connection between the two.

[0034] In some specific embodiments, such as Figures 3-5 As shown, the upper center plate 20 includes a center plate body 21 and a center plate boss 22. The center plate boss 22 is disposed on the center plate body 21, and an annular groove 23 is provided between the center plate boss 22 and the center plate body 21. It should be noted that for rail vehicles, in addition to the upper center plate 20, a lower center plate is also included. The lower center plate is disposed on the bogie and is provided with an annular boss that mates with the annular groove 23 of the upper center plate 20 to achieve positioning of the upper center plate 20 and the lower center plate. The upper center plate 20 and the lower center plate are provided with mounting holes for installing a center pin to achieve rotational engagement between the upper center plate and the lower center plate, thereby achieving load transfer of the vehicle.

[0035] In addition, this application also discloses a convertible, which includes the center plate assembly of the above embodiments, and therefore has the same technical effects as the above center plate assembly, so it will not be described again.

[0036] It should be noted that the various embodiments in this specification mainly describe the differences from other embodiments, and the same or similar parts between the various embodiments can be referred to each other.
