Problems solved by technology

Therefore, the existing series of suspension devices still have deficiencies in the ability to turn through a small radius of curvature and light weight, and it is difficult to adapt to the geographical environment of some European countries with many mountains and many curves. In terms of rail vehicle cooperation, these are also two of the many technical issues that are needed

Embodiment 1

[0023] Such as figure 1 , figure 2 with Figure 5 As shown, a series of suspension devices includes a base 5 , a top plate 2 , a conical spring and a limit stop, wherein the conical spring includes a rubber body 41 , a mandrel 3 and a casing 43 . The lower end of bogie 1 is provided with a stopper hole 11, a single conical spring is a rotating body, and two conical springs are arranged side by side along the longitudinal direction between the base 5 and the top plate 2, and the upper end of the mandrel 3 of the conical spring is separated by a gap. Fitting way is installed in the stopper hole 11. In the middle part of the mandrel 3, the rubber body 41 and the overcoat 43, there are interconnected cavities 7, and the lower end of the limit stop is engaged in the bottom plate 51 at the lower end of the base 5 in an interference fit manner. The upper end extends into the cavity 7 opened in the middle of the mandrel 3 . The upper end and the lower end of the axle box seat 9 a...

Abstract

The invention discloses a lightweight axle box built-in primary suspension device and a lightweight design method. An axle box seat is arranged on an axle box of a vehicle, a stop hole is formed in the lower end of a bogie, the lower end of the primary suspension device is installed in the axle box seat, and the upper end of the primary suspension device is installed in a stop hole of the bogie. According to the invention, the capacity of a vehicle for passing through a small-curvature-radius curve can be remarkably improved, the primary suspension space is greatly saved, and the weight of thebogie is reduced. The minimum curve passing radius of the bogie of the vehicle is remarkably reduced compared with that of a common bogie, so that the turning maneuverability and flexibility of the bogie are greatly improved, and the loading capacity, the dynamic performance and the critical speed of the whole vehicle are improved.

Description

technical field [0001] The invention relates to the field of rail vehicles, in particular to a lightweight method and structure of a primary suspension device. Background technique [0002] The existing primary suspension devices are arranged on both sides of the axle box. With this structure, the rotation angle of the bogie will be restricted by the primary suspension devices on both sides of the axle box when the vehicle turns with a small curvature. Moreover, the existing primary suspension devices Suspension device volume and quality are all bigger. Therefore, the existing series of suspension devices still have deficiencies in the ability to turn through a small radius of curvature and light weight, and it is difficult to adapt to the geographical environment of some European countries with many mountains and many curves. These are also two of the many technical issues that are required in terms of rail vehicle cooperation. Contents of the invention [0003] The tec...
