Embodiment Construction

[0035] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] The noise reduction ring provided in this embodiment is used for vibration and noise reduction of wheels, and includes a ring body 100 with an opening 200. The ring body 100 includes a first end face 110 and a second end face 120 on both sides of the opening 200. The first end face The first end surface 110 and the second end surface 120 can be completely staggered to press the ring body 100 together.

[0037] The wheels provided by this embodiment, such as Figure 6 As shown, it includes a rim 300 and a noise re...

Abstract

The invention provides a noise reduction ring and a wheel, and relates to the technical field of train noise reduction; the noise reduction ring is used for carrying out vibration and noise reductionof wheels, and comprises a ring body with an opening; the ring body comprises a first end face and a second end face which are located on two sides of the opening; the first end face and the second end face are in contact fit to form a complete circular ring from the ring body, and the first end face and the second end face can be completely staggered to press the ring body; the wheel comprises arim and the noise reduction ring; an annular groove matched with the noise reduction ring is formed in the inner wall of the rim, and the noise reduction ring is installed in the annular groove. In the noise reduction ring, the opening does not need to be connected through a connecting piece; the solid structure only comprises the ring body, and the structure is simple; during installation, the first end face and the second end face are staggered and the ring body is pressed, so that the installation is convenient and fast; after the first end face and the second end face are in matched contact, the ring body can form the complete circular ring, so that influences on wheel dynamic balance is reduced.

Description

technical field [0001] The invention relates to the technical field of train noise reduction, in particular to a noise reduction ring and a wheel. Background technique [0002] In recent years, the rail transit system has developed rapidly, and the running speed of rail vehicles has been greatly increased, and the resulting noise pollution of rail transit has also aroused people's strong concern. The vibration and noise generated during train operation will not only affect the ride experience of passengers in the train, but also affect the surrounding environment and residents. With the improvement of living standards, people's tolerance to noise decreases. Therefore, taking corresponding measures to reduce the vibration and noise generated during train operation is not only beneficial to environmental protection, but also conducive to the sustainable and healthy development of rail transit. [0003] Rail traffic noise mainly includes wheel-rail noise, aerodynamic noise, e...
