Abstract

The utility model provides a rubber suspension device for an axle box, which enables an axle box body to have enough strength to bear vertical force, horizontal force and longitudinal force simultaneously by installing rubber stacks at two ends of the axle box body, on the top of the axle box body as well as between trusses of the axle box body, so as to serve the purposes of simplifying the suspension device and reducing the weight of the axle box body. The utility model is characterized in that two end rubber stacks are arranged at the two ends of the axle box body, and are connected with the trusses; a top end rubber stack is arranged in the middle position of the top of the axle box body, and is connected with the trusses; and the central axes of the two end rubber stacks are parallel to the central axis of the top end rubber stack, and are perpendicular to the connection points of the trusses respectively. As the rubber stacks are capable of bearing forces from any direction, the distribution of the rubber stacks allows the axle box body to withstand vertical force, horizontal force and longitudinal force produced by the trusses at the same time, and ensures that the weight of the axle box body is reduced.

Description

Rubber type axle box suspension device

Technical Field

The utility model relates to an axle box linkage for bogie frame belongs to the machine-building field.

Background

The primary suspension device applied to the railway vehicle bogie at present only adopts the elastic buffer structures capable of bearing vertical loads at two ends of the axle box body, so that certain difficulty is brought to the structural design of the existing wheel pair axle box body.

If the axle box body can bear a large vertical force, the bearing arms at the two ends of the axle box body need to have enough rigidity and strength, and the weight of the axle box body is inevitably increased, so that the whole layout design of a bogie of the railway vehicle is not facilitated, and the driving safety of the railway vehicle during high-speed operation is also not facilitated.

SUMMERY OF THE UTILITY MODEL

A design aim at of the utility model provides a rubber formula axle box linkage to solve above-mentioned problem and design defect. Through the rubber piles respectively arranged between the two ends and the top of the axle box body and the framework, the axle box body can simultaneously bear enough strong vertical force, transverse force and longitudinal force, not only can the primary suspension device be simplified, but also the purpose of reducing the weight of the axle box body is achieved.

In order to achieve the purpose, the rubber type axle box suspension device is arranged between the bogie frame and the wheel pair axle box body. Wherein,

the two ends of the axle box body are provided with 2 end rubber piles connected with the framework, and the middle position of the top of the axle box body is provided with 1 top rubber pile connected with the framework.

The central axes of the 2 end rubber piles and the top rubber pile are parallel to each other and are respectively vertical to the connecting point of the framework.

As with the above-described solution features, the purpose of providing the end rubber piles and the top rubber piles, and the points of attachment to the frame, are different. The top rubber dome is primarily used to withstand vertical forces from the frame.

While the 2 end rubber stacks are primarily intended to withstand the lateral and longitudinal forces from the frame, only a small fraction of the vertical forces.

Through the distribution of the rubber piles bearing the acting forces in different directions, the axle box body can bear the vertical force, the transverse force and the longitudinal force from the framework, and meanwhile, the self weight of the axle box body is reduced.

In order to further improve the capability of the top rubber stack for bearing vertical force, a laminated rubber stack structure can be adopted, namely a laminated structure formed by integrally vulcanizing a rubber layer and a metal layer, wherein the rubber layer and the metal layer are arranged in a manner of being separated one by one.

In order to further improve the effect of the end rubber pile on bearing transverse force and longitudinal force, a conical structure formed by integrally vulcanizing rubber and a metal layer can be adopted.

Considering that the axle box body is respectively connected with the framework through the rubber piles, in order to improve the stress performance of the end rubber piles, the 2 connecting points of the end rubber piles connected with the framework have different vertical heights, namely, a certain height difference exists between the 2 end rubber piles.

As described above, the utility model discloses rubber formula axle box linkage's advantage is, can reduce the weight of axle box body, and the axle box body can bear great vertical power, horizontal power and vertical power simultaneously, is favorable to bogie overall structure design and improvement rail vehicle's functioning speed.

FIG. 2 is a schematic partial cross-sectional view of the present invention;

as shown in fig. 1 and 2, a frame 1, an end rubber pile 2, a top rubber pile 3, a shaft housing 4, a rubber layer 31, and a metal layer 32.

Detailed Description

Embodiment 1, as shown in fig. 1 and 2, a rubber-type axle box suspension is provided between a bogie frame 1 and a wheel-set axle box 4. Wherein,

at both ends of the axle box 4, there are 2 end rubber piles 2 connected to the frame 1, and the end rubber piles 2 have a tapered structure in which rubber and a metal layer are integrally vulcanized.

The 2 end rubber piles 2 are connected with the frame 1 at the connection points with certain height difference.

At the middle position of the top of the

axle box body

4, 1 top rubber pile 3 connected with the framework 1 is arranged. The top rubber layer 3 has a laminated structure in which a rubber layer 31 and a metal layer 32 are integrally vulcanized, and the rubber layer 31 and the metal layer 32 are arranged one by one with a space therebetween.

The central axes of the 2 end rubber piles 2 and the top rubber pile 3 are parallel to each other and are respectively perpendicular to the connecting point of the framework 1.

The top rubber pile 3 is used for bearing vertical force, and the 2 end rubber piles 2 are used for bearing transverse force and longitudinal force.
