Description

Technical Field

[0001] The utility model relates to the technical field of a noise reduction ring connector, a noise reduction ring and a noise reduction wheel, and in particular to a noise reduction ring connector, a noise reduction ring and a wheel which are convenient to store and install. Background Art

[0002] Noise reduction rings, also known as damping rings, are usually used to reduce noise during the rotation of train wheels. The noise reduction ring is usually installed in the noise reduction ring installation groove of the wheel, and the noise reduction ring is slightly stretched in the noise reduction ring installation groove by using a connector to improve the stability of the installation. Therefore, the sum of the length of the connector and the noise reduction ring is usually greater than the length of the noise reduction ring installation groove, and the connector needs to be compressed to a certain extent before the installation of the noise reduction ring can be completed.

[0003] In the prior art, utility model patent CN209096377U discloses a rail vehicle wheel noise reduction damping device, which uses a damping connector (spring telescopic rod) installed at the notch of the noise reduction ring to expand the noise reduction ring in the noise reduction ring installation groove, which can compensate for errors generated during processing, installation and use, greatly simplifying the installation process, and the damping connector will not fall off. However, during the installation process, the damping connector needs to be manually pressed, and then expanded at the notch of the noise reduction ring to complete the installation. In addition, the damping connector is in an expanded state without pressure, which will also take up more storage space.

[0004] In the prior art, the invention patent CN104723790A discloses a wheel damping ring connection device and connection method. During installation, the positioning pin is squeezed out of the connecting rod and inserted into the damping ring through an extrusion device to ensure that the connection device will not fall off from the open joint of the damping ring; a top screw is screwed in from the outside, and the top screw squeezes the balls on both sides to push out the two positioning pins. The operation is simple and easy to implement; a locking nut is set on the outer layer of the connecting rod, and the nut is mechanically fastened to ensure that the damping ring is tight and does not fall off. The notch of the noise reduction ring is propped open by the top screw. Although the connecting rod does not need to be manually pressed in advance, an additional tool is required to prop the positioning pin open at the notch of the noise reduction ring during the installation process. And the use of a top screw structure requires more precise mechanical manufacturing accuracy and a more complex installation method.

[0005] In the prior art, the utility model patent CN209521481U discloses an elastic connector for a damping ring, which uses a threaded connection that can provide a relatively large pressure, and a metal rubber spring with relatively large damping and stiffness, which can provide a sufficiently large preload force for the damping ring, and can compensate for the slight change in length of the notch of the damping ring due to climate change and long-term use, so that the damping ring can exert the maximum vibration reduction and noise reduction effect. However, the metal rubber spring with relatively large damping and stiffness is used, which can provide a sufficiently large preload force for the damping ring, and can compensate for the slight change in length of the notch of the damping ring due to climate change and long-term use. However, it requires a lot of manual effort to press the sleeve rod into the sleeve, which increases the strength of manual installation.

[0006] In the prior art, for example, the utility model CN210553920U discloses a noise reduction damping ring connector for a wheel, which has two pairs of circular through holes on the sleeve, so that the connector and the damping ring are connected without position restrictions, and the connector is suitable for connecting the damping ring in different situations. However, it is also necessary to manually press the telescopic rod into the sleeve during installation. Utility Model Content
