Example Embodiment

[0010] Such as figure 1 As shown, a wheel of a rail vehicle capable of damping and noise reduction includes a wheel body. The outer periphery of the wheel body is provided with a tread and a rim on one side of the tread. The tread surface is evenly provided with a plurality of tread holes, and the rim surface is evenly provided There are multiple rim holes; rubber is installed inside the tread hole and the rim hole. Among them, the diameter of the tread hole is 3mm-5mm, and the diameter of the rim hole is 3mm-5mm.

[0011] Such as figure 2 As shown, the wheel is rolling on the track, the tread and the rim are in contact with the rail, the tread and the rim are deformed by force, because the rim and the tread are both opened with small holes, by increasing the deformation variable to reduce vibration and energy absorption, reduce and eliminate The noise caused by wheel-rail contact friction and vibration; at the same time, it deforms and squeezes the rubber material inside the s...

Abstract

The invention relates to a rail vehicle wheel that damps and muffles noises generated by contacting with a wheel/rail on a rail vehicle, in particular to a wheel, comprising a wheel main body, whereinthe outer periphery of the wheel main body is provided with a tread and a rim on one side of the tread, a plurality of tread holes are uniformly arranged on the tread surface, and a plurality of rimholes are uniformly arranged on the surface of the rim. The inside of the tread hole and the wheel rim hole is provided with rubber. The rail vehicle wheel that damps and muffles noises can reduce the noise generated by the friction vibration between the wheel and the track when the rail vehicle is running, At that same time, it can be design and manufactured on the basi of the existing wheelsetsto achieve the purpose of vibration reduction and noise reduction when the rail vehicle is running, and the wheel need not be redesigned, the structure is simple, the other performance of the wheel is basically not affected, and the wheelsets are easy to implement and the materials are easy to obtain.

Description

technical field [0001] The invention relates to an on-rail vehicle, in particular to a wheel capable of reducing the noise generated by contacting the wheel and rail. Background technique [0002] Since the reform and opening up, my country's science and technology and national economy have achieved rapid development. In recent years, rail transit is developing at an unprecedented speed in our country with its many advantages. The large-scale construction of high-speed railways, subways, and light rails not only meets travel needs to a large extent, relieves traffic pressure, and solves problems such as urban traffic congestion, but also promotes urban and rural construction and economic development, and reduces pollution. social benefits. However, while the rail transit system provides many conveniences for people, it inevitably brings many problems, and the noise of rail vehicles is one of the main problems. The running noise of rail vehicles not only affects the ride ex...
