Problems solved by technology

[0012] The purpose of the present invention is to solve the problem that the adjustment of the existing hourglass-shaped rubber spring cannot adjust the stiffness under heavy load. When the product is used under heavy load, the rubber surface of the rubber outer drum is prone to wrinkles, and there is a problem of rubber cracking for a long time in operation. Propose a kind of new hourglass type rubber spring stiffness adjustment method and hourglass type rubber spring; This kind of new hourglass type rubber spring stiffness adjustment method and hourglass type rubber spring can provide the required stiffness of hourglass type rubber spring under heavy load, And it can effectively prevent wrinkles on the rubber profile and improve the fatigue resistance of the hourglass-shaped rubber spring

Embodiment 1

[0043] by attaching figure 2 It can be seen that the present invention relates to an hourglass spring that realizes the method for adjusting the variable stiffness of the hourglass spring through a hard stop, including an upper end plate 1, a lower end plate 2, an intermediate support plate 3 and an hourglass-shaped rubber body 4; the hourglass-shaped rubber body The shape of 4 is hourglass-shaped, and the hourglass-shaped rubber body 4 is integrally vulcanized together with the lower surface of the upper end plate 1 and the upper surface of the lower end plate 2, and the middle support plate 3 is wrapped and vulcanized on the middle part of the hourglass-shaped rubber body 4 to form a belt. The hourglass spring of the intermediate partition; the inside of the hourglass-shaped rubber body is all solid rubber, and hard stoppers 5 are respectively set on the upper end plate 1, the lower end plate 2 and the middle support plate 3 of the hourglass rubber spring, through the upper ...

Embodiment 2

[0051] The principle of the second embodiment is the same as that of the first embodiment, except that the structure is slightly different. The hourglass rubber spring adopts an upper end plate combination, a lower end plate combination, a middle support plate and rubber, and an upper end plate combination and a lower end plate of the rubber. The plate combination is respectively connected with a hard stop, and the hard stop can be connected to the upper and lower plates by welding; the middle support plate is connected to the middle part of the rubber; and there is a hard stop in the middle of the middle support plate; the rubber vulcanized body has a small middle diameter 1. Hourglass structure with large diameters at both ends; the ratio of the minimum external diameter of the middle part of the rubber to the maximum diameter of both ends of the rubber is less than or equal to 1 / 2, and the diameter of the rubber cannot be smaller than the diameter of the hard stop of the midd...

Abstract

A method for adjusting the variable stiffness of an hourglass spring through a hard stop and the hourglass spring, which adopts an hourglass-shaped rubber body whose inner surface is completely solid, and sets hard stops on the upper end plate, lower end plate, and middle support plate of the hourglass rubber spring respectively, through The contact changes between the upper and lower end plates, the lower end plates and the upper and lower hard stops on the middle support plate and the solid rubber adjust the stiffness of the hourglass spring and improve the stress condition in the hourglass spring. In the middle of the solid hourglass-shaped rubber body, hard stops are respectively placed under the upper end plate, above the lower end plate, and on the upper and lower sides of the middle support plate. These hard stops are respectively vulcanized together with the hourglass-shaped rubber body. These hard stops act within the hourglass rubber body, adjusting the stiffness of the hourglass rubber spring. The present invention can effectively adjust the stiffness of the hourglass rubber spring by setting a hard stop in the hourglass-shaped rubber body, thereby realizing variable stiffness of the hourglass rubber spring.

Description

technical field [0001] The invention relates to a performance adjustment method and structure of rail vehicle components, in particular to a method for adjusting the variable stiffness of an hourglass spring through a hard stop and an hourglass spring, the method for adjusting the variable stiffness of an hourglass spring through a hard stop And the hourglass spring, which can effectively adjust the variable stiffness of the hourglass spring, improve the internal stress of the hourglass spring, and improve the anti-fatigue performance of the hourglass spring; it belongs to the technical field of rail vehicle parts manufacturing. Background technique [0002] With the rapid development of urban rail transit, low-floor vehicles have gradually entered the lives of the general public. They are installed between the frame and the car body, mainly bearing pressure and shear loads, supporting, transmitting and isolating loads, ensuring that the bogie frame and The connection betwee...
