[0054] Example 2: see Image 6 , an auxiliary spring comprising:

[0055] Base 2;

[0056] The rubber stack 1 is located above the base 2 and installed on the base 2; the rubber stack 1 includes:

[0057] Rubber body 101;

[0058] The separator 102 is located outside the rubber body 101 and divides the rubber body 101 into upper and lower parts. The outer surface of the rubber body above the separator 102 is configured as a convex arc surface structure, and the outer surface of the rubber body below the separator 102 is configured as an inner concave arc surface. structure;

[0059] The mandrel 3 is installed inside the rubber body 101 and extends out of the rubber body 101;

[0060] The supporting seat 4 is arranged above the mandrel 3 and connected with the mandrel 3 .

[0061] continue to see Image 6 , The bottom of the rubber body 101 is provided with a bottom plate 5 , and the rubber body 101 is installed on the base 2 through the bottom plate 5 .

[0062] Specifi...

Embodiment 3

[0074] Embodiment 3: see Figure 7 , an air spring system, including an air spring and an auxiliary spring connected below the air spring, the auxiliary spring adopts the auxiliary spring described in Embodiment 2, and the air spring is installed on the support seat 4 of the auxiliary spring.

[0075] continue to see Figure 7 , the air spring includes:

[0076] Upper cover 6;

[0077] The airbag 7 is arranged under the upper cover 6 , the top of the airbag 7 is connected with the upper cover 6 through a buckle 8 , and the bottom of the airbag 7 is installed on the support seat 4 .

[0078] Specifically, continue to see Figure 7 , the clasp 8 is connected to the upper cover plate 6 through the third connecting piece 903.

Abstract

The invention relates to a rubber stack, an auxiliary spring and an air spring system. The rubber stack includes: a rubber body; Convex arc surface structure, the outer surface of the rubber body under the partition is set as concave arc surface structure. The auxiliary spring includes the aforementioned rubber stack. The air spring includes the aforementioned auxiliary spring. The invention has large lateral and torsional deformation capacity, safe structure, less metal structure and light weight.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and relates to damping technology, in particular to a rubber pile, an auxiliary spring and an air spring system. Background technique [0002] Air springs are widely used in rail vehicles because of their small natural frequency and large lateral displacement capacity. In the existing rail vehicle design, when there is air, the lateral deformation required to be borne by the air spring is increasing. At this time, the auxiliary spring is required to share part of the lateral deformation; when there is no air, the small vertical stiffness of the auxiliary spring can effectively Reduce the derailment coefficient of the vehicle and make the vehicle safer. [0003] The common types of existing auxiliary springs are: flat rubber stack auxiliary springs (see figure 1 ), hourglass rubber stack auxiliary spring (see figure 2 ), conical rubber stack auxiliary spring (see image 3 ), conical rubb...
