Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] In some specific embodiments of this utility model, such as Figures 1 to 9 As shown, this solution provides a vibration reduction structure for a rail vehicle, including: a mounting base 10, which is connected to the frame 30 of the rail vehicle, and the mounting base 10 has a mounting groove 11 inside; a herringbone spring assembly 20, which is disposed in the mounting groove 11, and the side of the herringbone spring assembly 20 away from the mounting groove 11 is connected to the gearbox 40 of the rail vehicle; wherein, the mounting groove 11 is at least used to limit the displacement of the herringbone spring assembly 20 in the lateral direction.

[0044] In some possible embodiments of this utility model, the mounting base 10 includes: a mounting plate 12, a safety support 13, and three side plates 14; the mounting plate 12 forms the bottom of the mounting groove 11; the safety support 13 and the three side plates 14 are connected to each other and disposed on the surface of the mounting plate 12; wherein the mounting plate 12, the safety support 13, and the three side plates 14 enclose to form a mounting groove 11 with one side open.

[0045] Specifically, this embodiment provides an implementation of the mounting base 10, which is composed of three parts: mounting plate 12, safety support 13 and side plate 14, thereby forming a mounting groove 11, realizing the installation of the herringbone spring assembly 20. This setting meets the installation and positioning requirements of the herringbone spring assembly 20, and avoids the herringbone spring assembly 20 from shifting due to vibration during the operation of the rail vehicle, thus preventing the existence of safety hazards.

[0046] It should be noted that the mounting plate 12 and the three side plates 14 are fixedly connected, while the safety bracket 13 and the side plates 14 or the safety bracket 13 and the mounting plate 12 are detachably connected. This configuration makes the installation of the herringbone spring assembly 20 more convenient. During installation, the safety bracket 13 is removed. The mounting slot 11 is open at the top and sides, making it easier for the herringbone spring assembly 20 to be installed into the mounting slot 11. Then, the safety bracket 13 is installed in place, thereby realizing the installation of the herringbone spring assembly 20.

[0047] In some possible embodiments of this utility model, the safety holder 13 has two symmetrically arranged extensions 131, and the two extensions 131 are respectively slidably engaged with the side plate 14 opposite to the outer side of the mounting groove 11; the side plate 14 is provided with a sliding groove 141 corresponding to the extensions 131.

[0048] Specifically, this embodiment provides an implementation of a safety bracket 13 and a side plate 14. Extension sections 131 are provided on two opposite sides of the safety bracket 13, and a sliding groove 141 is provided at the corresponding position of the side plate 14 that cooperates with the safety bracket 13.

[0051] In some possible embodiments of this utility model, the first through hole 132 is an elongated hole.

[0052] Specifically, this embodiment provides an implementation of the first through hole 132, which is set as an elongated hole, so that during the installation process, the size of the mounting groove 11 can be adjusted within a certain range according to the different sizes of the herringbone spring assembly 20, and the herringbone spring assembly 20 can also be adjusted to different degrees of compression.

[0053] In some possible embodiments of this utility model, the mounting plate 12 includes: a plate body 121, which is connected to the mounting bracket and three side plates 14 and surrounds to form a mounting groove 11; a first positioning rib 122, which is disposed on the other side of the plate body 121 where the mounting groove 11 is formed; and a second positioning rib 123, which is arranged alternately with the first positioning rib 122 on the same side of the mounting groove 11.

[0054] Specifically, this embodiment provides an implementation of the mounting plate 12.

The first positioning rib 122 and the second positioning rib 123 are arranged in a T-shape, so that the mounting base 10 can be effectively and stably positioned in both the longitudinal and transverse directions.

[0059] It should be noted that the frame 30 is provided with a positioning groove 31, and the first positioning rib 122 and the second positioning rib 123 respectively cooperate with the positioning groove 31 to achieve positioning of the mounting base 10 and prevent the primary spring from moving.

[0060] In some possible embodiments of this utility model, the number of first positioning ribs 122 is odd or even; the number of second positioning ribs 123 is even or odd.
