Embodiment Construction

[0012] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0013] The damper used in the present invention for reducing vibration and noise of wheels is composed of a mounting plate 1 and multilayer friction plates 2, and the number of friction plates 2 can also be increased or decreased according to actual needs such as mass ratio. The friction plate 2 and the mounting plate 1 are superimposed and mounted on the wheel 6 with bolts 7 . When the wheel vibrates and deforms during the running pr...

Abstract

The invention provides a multi-layer friction damper for a vehicle wheel. The multi-layer friction damper comprises an installing plate (1) and a multi-layer friction plate (2). The multi-layer friction plate (2) is superposed on the installing plate (1). The multi-layer friction damper uses a frictional damping theory adequately. Compared with a single-layer friction damping ring, the multi-layerstructure of the multi-layer friction damper can provide the larger damping. Relative to a damper using a viscous-elastic material, the multi-layer friction damper has the better environmental suitability. The damping effect of the multi-layer friction damper is slightly changed along with the change of the environment, and the multi-layer friction damper can be used better in a long-distance line. In addition, the machining and the installing of the multi-layer friction damper are very easy, so the consumption of manpower and material resources is reduced in the greater degree.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction and noise reduction of train wheels, in particular to a multi-layer friction damper for wheels. Background technique [0002] The development of high-speed railway brings convenience to people, but also brings some negative problems. Vibration noise is one of them. Excessive vibration and noise level not only affects the comfort of passengers but also affects the normal life of residents along the way. Therefore, taking measures to reduce the vibration and noise of high-speed railways has become an important issue accompanying the development of high-speed railways. As the speed of the train increases, the noise problem of the wheels grows faster than the rest of the wheel-rail system, so measures must be taken to reduce the vibration and noise of the wheels. Increasing wheel damping is one of the most economical and effective methods to reduce wheel vibration and noise, and there a...
