Abstract
The utility model provides a take wheel of damping ring can make the wheel under the great condition of wheel pair transverse vibration, provides better transverse damping effect, realizes better damping noise reduction effect. The utility model discloses a take wheel of damping ring, including wheel body (1), rim (1.3) on wheel body (1) sets up damping ring (2) in the at least one side upper groove of rim (1.3), its characterized in that the cross-section of damping ring (2) is the U type. The utility model discloses a with damping ring cross-section design for the U type to improve one-way damping, realize providing bigger transverse damping effect when wheel pair transverse vibration is great, play and restrain the radial and transverse vibration effect of wheel, reduce the outside radiation noise of wheel and vibration, realize better damping noise reduction effect.
Description
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.

Detailed Description
The technical solution of the present invention will be further described below with reference to the embodiments of the present invention.
As shown in fig. 1, the wheel with the damping ring provided in this embodiment includes a damping ring 2 and a wheel 1, where the wheel structure includes a tread 1.2, a rim 1.1, a rim 1.3, a web 1.4, and a hub 1.5.
The cross-section of damping ring is the U type, installs and opens the circular fabrication hole of an open type that has a diameter to be 13mm in the transition department of rim to the U type opening side of damping ring is towards open type fabrication hole, and the damping ring laminating is in downthehole wall.
