Description

Wheel with damping ring

Technical Field

The utility model relates to a wheel with damping ring, damping ring's effect reduces wheel vibration noise.

Background

Vibration and noise of rail transit have become major factors of urban environmental problems, and rail transit noise mainly includes wheel-track noise. The wheel-rail noise is divided into rolling noise, impact noise, and curve squeal. Research has shown that wheel-rail noise is a major source of track noise when the train is traveling at speeds less than 250 km/h. While increasing wheel damping is an effective way to reduce vibrational acoustic radiation.

In the prior art, CN 201800444U describes a noise reduction wheel suitable for urban subway traffic vehicles, which includes a hub, a spoke plate, a rim, a wheel flange and a tread. The improvement is that: the inner edges of the two sides of the rim are provided with annular grooves, and metal rings are embedded in the annular grooves.

CN 205800645U describes a synthetic damping ring for vehicle wheels, consisting of: synthetic damping ring, synthetic damping ring including hollow metal ring, hollow metal ring internally mounted have hollow rubber ring, hollow rubber ring internally mounted have solid metal ring, synthetic damping ring install in the inboard rectangular channel of wheel rim, the opening is connected with elastic element.

The conventional damping ring is in a solid state and provides the same damping in the transverse direction and the radial direction, but cannot provide enough transverse damping when the transverse vibration of the whole wheel pair is large when the rail is abnormally damaged, and the condition needs a wheel damping ring with larger transverse damping to meet the requirement.

Disclosure of Invention

The utility model provides a novel damping ring of structure can make the wheel under the great condition of wheel pair transverse vibration, provides better transverse damping effect, realizes better damping noise reduction effect.

In order to solve the technical problem, the utility model provides a pair of take wheel of damping ring, including wheel body (1), rim (1.3) on wheel body (1) sets up damping ring (2) in rim (1.3) at least one side upper groove, wherein the cross-section of damping ring (2) is the U type.

The utility model provides an among the wheel of taking damping ring, the cross-section of damping ring wherein is the U type, that is to say this damping ring is hollow, and has the opening.

And the position of the damping ring in the wheel can be selected at the transition of the rim. The so-called transition of the rim means: the wheel rim and the wheel disc are connected at the transition.

The utility model discloses a further improvement is that the preferred cross-section U type opening side of damping ring (2) of the mounted position state of damping ring is towards the recess inboard and laminating rim.

A further preferred solution is that the recess is an open circular fabrication hole of 12 mm diameter. The sizes of the wheels of the common urban rail vehicles can be unified by the aperture with the size. When the diameters of the wheels are greatly different, the opening type circular aperture needs to be recalculated and selected. The open circular fabrication hole is a circular mounting hole which is not closed and is used for mounting the U-shaped damping ring.

According to the invention, the wheel damping ring is designed into a U shape, so that the one-way damping is improved, and a larger transverse damping effect is provided when the transverse vibration of the wheel pair is larger. When the rail is abnormally damaged and the transverse vibration of the whole wheel set is large, sufficient transverse damping and radial damping are provided, the radial and transverse vibration of the wheel is restrained through the friction damping energy consumption of the wheel body and the damping ring with the U-shaped section, the outward radiation noise and vibration of the wheel are reduced, and the better vibration and noise reduction effects are realized.
