Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0030] In order to solve the problems of reduced service life of the rigid wheel 1 and ride comfort caused by noise and high-frequency vibration caused by the rolling of the tire, the present invention uses particle damping technology to study and analyze the wheel 1, and proposes a wheel disc type for rail vehicles. Particle damping shock absorbers such as figure 1 with figure 2 As shown, the shock absorber includes:

[0031] The disc housing 2 is made of composite damping steel plate, and is provided with a plurality of concentric annular sealing grooves 3. The number of annular ...

Abstract

The invention relates to a wheel disc type particle damping absorber for a rail vehicle. The wheel disc type particle damping absorber comprises disc type shells concentrically arranged on wheels, wherein multiple concentric annular sealing grooves are formed in the disc type shells; and multiple spherical damping particles are filled in the annular sealing grooves. Compared with the prior art, the wheel disc type particle damping absorber fully uses a traditional wheel structure, is provided with the absorber having simple and effective structure on the basis of guaranteeing the wheel rigidity and strength, and has such advantages as low additional mass, low manufacturing cost, good damping effect and high reliability.

Description

technical field [0001] The invention relates to the field of rail vehicle vibration reduction, in particular to a wheel disk particle damping shock absorber for rail vehicles. Background technique [0002] Particle damping shock absorber is a new type of shock absorber based on particle damping technology. It has simple structure, low cost, maintenance-free, obvious damping effect, and strong adaptability to harsh environments. It has an increasingly wide range of applications, mainly in the field of passive control. , especially in some harsh working conditions. [0003] In the existing rigid wheels, noise and high-frequency vibration occur due to the rolling of the tire, which will be strengthened by the action of the wheel center diaphragm and transmitted to the car body in the form of body noise, resulting in a decrease in the ride comfort of the wheel. And the wheel brake disc is bolted to the wheel, which may cause safety problems due to vibration. At present, the re...
