Example Embodiment

[0039] Example one

[0040] Such as figure 1 As shown in Figure 3, a conical spring includes an inner cone 1, a rubber body 2 and an outer cone 3. The lower end of the inner cone 1 extends outward to form an annular inner cone boss 11. The upper end surface 21 of the rubber body 2 is a three-stage multi-stage downslope structure, which is a first annular straight section 211, a second annular straight section 212, and a third annular straight section 213. Each of the two annular straight sections A circular rounded section 22 is used for transition between. In this embodiment, the rounded radii of the two annular rounded sections 22 on the upper end surface of the rubber body 2 are both 4-8 mm. The rubber body 2 surrounds the periphery of the inner cone 1, and the outer cone 3 surrounds the periphery of the rubber body 2. The inner cone 1 and the outer cone 3 are metal parts. The inner cone 1 and the outer cone 3 and the rubber body 2 are vulcanized into a whole through the adh...

Example Embodiment

[0049] Example two

[0050] The structure is roughly the same as that of the first embodiment, but the upper end of the rubber body 2 does not adopt a gentle straight edge transition, but a gentle curve edge for the transition. The upper end of the rubber body 2 is composed of four annular straight sections 21 and three annular circles. The corner section 22, and the lower end of the rubber body 2 are three annular straight sections 21 and two annular rounded corner sections 22. In this way, changing the number of segments of the ring-shaped straight section 21 can change the number of times the conical spring has changed stiffness, that is, the number of times of changing the stiffness of the cone spring can be changed by adjusting the number of segments of the ring-shaped straight section 21. Increasing or reducing the number of the annular straight section 21 can still make the cone spring from no load to the maximum vertical load process, the upper and lower ends of the rubbe...

Abstract

The invention provides an upper end surface of a tapered spring rubber body, and a method and a product for preventing folds and cracks. The upper end surface comprises an inner cone, a rubber body and an outer cone, wherein the rubber body is arranged around the periphery of the inner cone; the outer cone is arranged around the periphery of the rubber body; a rubber metal spring which is conically arranged is formed by the rubber body, the inner cone and the outer cone; the upper end surface of the rubber body is connected with the inner cone and the outer cone of the tapered spring, respectively; the rubber body has a gradual descending tendency from the connection part of the rubber body and the outer cone to the inner cone of the rubber body; the upper end surface of the tapered spring rubber body is characterized by being in a multi-section downhill combined profile structure; the upper end surface of the rubber body is formed by combining a plurality of sections of annular end surfaces with different shapes, gradients and lengths. The profile shape of the upper end surface is changed so that the variable stiffness of the tapered spring is adjusted; the upper end surface of the tapered spring rubber body is divided into more than two sections of multi-section profile combination; all sections of the profile have different shapes, gradients and lengths.

Description

technical field [0001] The present invention relates to the improvement of conical springs on locomotives, in particular to a method for adjusting the stiffness of the conical springs and the structure of the upper surface of the conical springs, the method and the structure of the conical springs can realize multiple stiffness changes of the conical springs, and Prevents conical spring rubber from cracking due to wrinkling when compressed with use. It belongs to the technical field of elastic damping. Background technique [0002] The conical spring is also called the axle box spring, which mainly refers to the spring with damping effect combined with metal and rubber on the locomotive. The conical spring is installed between the axle box and the frame of the rail locomotive to support, dampen and reduce noise. It is a commonly used rubber-metal composite vibration- and noise-reducing element. On the car body, the main function is to bear the load of the car body and fram...
