Problems solved by technology

However, due to the limitations of the rubber material, the dynamic stiffness of the rubber conical spring decreases with the increase of the frequency, and high-frequency dynamic softening occurs; at the same time, the damping of the rubber material is small, and the ability to dissipate vibration energy is limited.

Abstract

The invention relates to a chamber for a liquid composite spring. The chamber comprises an outer wall, an upper liquid chamber arranged in an upper portion inside the outer wall and a lower liquid chamber arranged in a lower portion inside the outer wall, wherein the upper liquid chamber is filled with liquid, the lower liquid chamber is filled with liquid and capable of communicating with the upper liquid chamber, the bottom of the outer wall is provided with a sealing piece for sealing the lower liquid chamber, and the sealing piece can be deformed so as to enable the lower liquid chamber tobe constructed as a flexible chamber. According to chamber, the rigid outer wall and the flexible sealing piece are arranged, and the volume and the shape of the lower liquid chamber can be changed through the flexible sealing piece, so that the chamber becomes the flexible chamber.

Description

technical field [0001] The invention relates to a chamber for a liquid compound spring for a liquid compound spring of a vehicle, in particular a rail vehicle. Background technique [0002] When the vehicle is running on the track, complex vibration phenomena are accompanied by it. Therefore, it is essential to install a spring device on the railway vehicle to attenuate mechanical vibration. Traditional rubber conical springs are easy to obtain different stiffness values ​​in the vertical, transverse and longitudinal directions, and have good nonlinear characteristics, so they can better meet the general axle box suspension requirements. However, due to the limitations of the rubber material, the dynamic stiffness of the rubber conical spring decreases with the increase of the frequency, and high-frequency dynamic softening occurs; at the same time, the damping of the rubber material is small, and the ability to dissipate vibration energy is limited.
