Description

Technical Field

[0001] This utility model relates to the field of wheel noise reduction ring technology, and in particular to a wheel noise reduction ring joint structure. Background Technology

[0002] Wheel noise reduction rings are mostly used on train wheels, and to a lesser extent on automobile wheels. Currently, wheel noise reduction rings consist of a steel ring and a preload bolt. One connection method involves the preload bolt connecting the two ends of the steel ring via an elastic element such as a spring. However, after prolonged use, the elastic element in this type of wheel noise reduction ring may deform beyond its limit, easily causing the preload bolt to break off from the steel ring. This not only fails to reduce noise but also poses a safety hazard. Another connection method is direct welding, which is cumbersome and involves complex procedures.

[0003] There is another connection method that uses pre-tightening components. Due to processing errors, component wear, and other reasons, there is a gap at the connection between the pre-tightening component and the muffler ring. The muffler ring may wobble in the muffler groove and be not securely installed.

[0004] Therefore, to address the above issues, a silencer ring connector structure can be designed to eliminate the gap between the preload and the silencer ring, minimizing the possibility of the silencer ring being poorly installed due to the presence of gaps. Utility Model Content

[0005] To overcome the problem of the sound-absorbing ring not being installed securely due to the gap between the preload and the sound-absorbing ring.

[0006] The technical solution of this utility model is as follows: a wheel muffler ring joint structure, including a muffler ring, the muffler ring including a broken section of the ring body and grooves opened at both ends of the broken section on the ring body, the muffler ring being fixed in the muffler groove in the wheel by a pre-tightening member, a gap-eliminating component being provided in the groove, an exhaust component and a sealing component being installed on the ring body, gas can flow between the gap-eliminating component and the exhaust component, the sealing component is used to prevent gas from flowing out of the exhaust component into the external environment, and the gap-eliminating component is used to eliminate the gap between the pre-tightening member and the groove; The seam assembly includes a pressure module, an expansion module, and a seam-eliminating component installed in a groove. The expansion module is used to drive the seam-eliminating end plate closer to or away from the pre-tightening component. When the pre-tightening component enters the groove, gas flows from the pressure module into the expansion module, and the seam-eliminating end plate approaches until it is in close contact with the pre-tightening component. When the pre-tightening component leaves the groove, gas flows from the expansion module into the pressure module, and the seam-eliminating end plate moves away from the pre-tightening component. The pre-tightening component includes a steel sleeve, a steel core, a flange, and bolts. The steel core is movably connected inside the steel sleeve, the flange protrudes from both ends of the steel sleeve, and the steel core is provided with a ramp structure.

[0007] Preferably, the pressure module includes a first airbag installed in the groove. When the pretensioner enters the groove, the first airbag is compressed, and the gas inside flows into the expansion module.

[0008] Preferably, the expansion module includes a connecting pipe with one end connected to the first airbag and a second airbag installed in the groove. The other end of the connecting pipe is connected to the second airbag. When gas flows into the second airbag through the connecting pipe, the seam-eliminating component approaches and adheres tightly to the pre-tightening component.

[0009] Preferably, the seam elimination component includes a seam elimination end plate, which is movably connected in the groove, and the surface of the seam elimination end plate is provided with an anti-slip layer.

[0010] Preferably, an elastic element is installed in the No. 1 airbag. When the pretensioner leaves the groove, the elastic element is used to drive the No. 1 airbag to open, and gas flows into the No. 1 airbag from the expansion module. The elastic element includes a compression spring, both ends of which are connected to the inner wall of the No. 1 airbag. When the pretensioner enters the groove, the compression spring is compressed synchronously with the No. 1 airbag.

[0011] Preferably, a channel groove is provided on the ring body, one end of which is connected to a corresponding groove, and the other end extends through to the side surface of the ring body. The exhaust assembly is disposed in the channel groove. The exhaust assembly includes an exhaust pipe with one end connected to the pressure module and the other end of which extends to the side surface of the ring body. When gas flows out from the gap-eliminating assembly through the exhaust pipe, the gap-eliminating component moves away from the pre-tightening component.

[0012] Preferably, the sealing assembly includes a plug mounted on the channel groove, the plug being used to close or open the exhaust pipe, so that when the exhaust pipe is open, gas flows out through the exhaust pipe into the external environment.

[0013] The beneficial effects of this utility model are:

[0014] 1. By using the gap-eliminating components set in the groove, after the flange of the pre-tightening component enters the groove, the gap-eliminating components on both sides will abut against the side wall of the flange, so that the ring will not wobble in the direction parallel to the wheel axis due to the gap between the flange and the groove, thus improving the installation stability of the noise-eliminating ring.

[0015] 2. By utilizing the exhaust assembly, when removing the pre-tightening component from the muffler ring, the gap-eliminating component can be disengaged from the flange in advance, thus avoiding excessive frictional resistance between the flange and the gap-eliminating component when pulling out the pre-tightening component.

[0016] 3. By using an exhaust pipe and an external inflation device, gas can be easily replenished after it is lost in the gap-eliminating assembly. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5This utility model provides an embodiment: a wheel muffler ring connector structure, including a muffler ring, the muffler ring including a broken ring body 101 and grooves 102 formed at both ends of the broken ring body 101, the muffler ring being fixed in the muffler groove in the wheel by a pre-tightening member, a gap-eliminating component being provided in the groove 102, an exhaust component and a sealing component being installed on the ring body 101, gas can flow between the gap-eliminating component and the exhaust component, the sealing component is used to prevent gas from flowing out of the exhaust component into the external environment, and the gap-eliminating component is used to eliminate the gap between the pre-tightening member and the groove 102; the gap-eliminating component includes a pressure-bearing module, an expansion module and a gap-eliminating member installed in the groove 102, the expansion module is used to drive the gap-eliminating end plate 305 to move closer to or away from the pre-tightening member; when the pre-tightening member enters the groove 102, gas flows from the pressure-bearing module into the expansion module, and the gap-eliminating end plate 305 moves closer to until it is in close contact with the pre-tightening member; when the pre-tightening member leaves ... At 02, gas flows from the expansion module into the pressure-bearing module. The gap-eliminating end plate 305 moves away from the pre-tightening component. When the pre-tightening component is connected to the ring 101, the bolt 204 is screwed into the steel sleeve 201. The inclined platform structure on the steel core 202 causes the steel core 202 to extend until the flange 203 enters the groove 102, tightening the ring 101 and fixing it in the silencing groove. The flange 203 extends into the groove 102, squeezing the pressure-bearing module, causing the gas in the pressure-bearing module to flow into the expansion module (at this time, the exhaust component is in the closed state by the sealing component). The expansion module pushes the gap-eliminating component close to the flange 203 until it abuts against the flange 203, eliminating the gap between the flange 203 and the groove 102. When it is necessary to remove the pre-tightening component from the ring 101, first remove the sealing component. The gas in the gap-eliminating component flows out through the exhaust component, and the gap-eliminating component separates from the flange 203. At this time, the bolt 204 can be turned to remove the pre-tightening component from the ring 101.

[0025] Please see Figures 2-5In this embodiment, the pressure-bearing module includes a first airbag 301 installed in the groove 102. When the pre-tensioning member enters the groove 102, the first airbag 301 is compressed, and the gas inside flows into the expansion module. The expansion module includes a connecting pipe 302 connected at one end to the first airbag 301 and a second airbag 303 installed in the groove 102. The other end of the connecting pipe 302 is connected to the second airbag 303. When gas flows into the second airbag 303 through the connecting pipe 302, the seam-reducing member approaches and adheres tightly to the pre-tensioning member. The seam-reducing member includes a seam-reducing end plate 305, which is movably connected in the groove 102. The surface of the seam-reducing end plate 305 is provided with an anti-slip layer. An elastic member 304 is installed in the first airbag 301. When the pre-tensioning member leaves the groove 102, the elastic member 304 is used to drive the first airbag 301 to open, and gas flows into the first airbag 301 from the expansion module. The elastic member 304 includes a compression spring, and the compression spring has two... Both ends are connected to the inner wall of the first airbag 301. When the pre-tightening member enters the groove 102, the compression spring is compressed synchronously with the first airbag 301. During the process of the flange 203 entering the groove 102, the first airbag 301 is gradually compressed (overcoming the elastic force of the elastic member 304, which can be the compression spring in this embodiment, or an elastic rubber member, etc.), so that the gas in the first airbag 301 enters the second airbag 303 through the connecting pipe 302. The second airbag 303 expands and pushes the seam-eliminating end plate 305 (the seam-eliminating end plate 305 is slidably connected to the cavity inside the groove 102 by a keyway. In actual use, the structural size of the seam-eliminating member can also be adjusted as needed to adapt to the flange 203 with different outer contours, so that the seam-eliminating member and the flange 203 fit more closely) out and close to the flange 203 until the seam-eliminating end plate 305 is tightly attached to the side wall of the flange 203, restricting the flange 203 from shaking in the groove 102.

[0026] Please see Figures 3-5In this embodiment, a channel groove is formed on the ring 101. One end of the channel groove communicates with the corresponding groove 102, and the other end extends through to the side surface of the ring 101. The exhaust assembly is disposed in the channel groove. The exhaust assembly includes an exhaust pipe 401 with one end connected to the pressure-bearing module and the other end extending to the side surface of the ring 101. When gas flows out from the gap-reducing assembly through the exhaust pipe 401, the gap-reducing component moves away from the pre-tightening component. The sealing assembly includes a plug 402 installed on the channel groove. The plug 402 is used to close or open the exhaust pipe 401. When the exhaust pipe 401 is open, gas flows out to the external environment through the exhaust pipe 401. To disassemble the preload and muffler ring, first remove the plug 402 from the ring body 101 (in this embodiment, a threaded connection is used, that is, rotate the plug 402 to disengage it from the muffler ring. It is worth noting that the opening of the channel groove is located on the side surface of the muffler ring, that is, the plug 402 is in a fully exposed state, and the user can easily access and operate it). Open the exhaust pipe 401, and the gas in the first airbag 301 and the second airbag 303 flows out through the exhaust pipe 401. As the second airbag 303 contracts, the muffler part disengages from the flange 203. At this time, rotate the bolt 204 to easily pull the flange 203 out of the groove 102.

[0027] Working principle: The user aligns the flange 203 with the groove 102, then screws the bolt 204 into the steel sleeve 201, allowing the steel core 202 to extend until the flange 203 enters the groove 102. As the flange 203 enters, the first airbag 301 is compressed, causing the gas inside to flow into the second airbag 303 through the connecting pipe 302. The second airbag 303 inflates, pushing the seam-eliminating end plate 305 out to contact the side wall of the flange 203 (the anti-slip layer on the seam-eliminating end plate 305 increases the static friction between it and the flange 203). (The anti-slip layer can be made of silicone rubber material). At this time, the pre-tightening component will tighten the ring 101 and fix it in the sound-absorbing groove. When it is necessary to separate the pre-tightening component from the ring 101, first remove the plug 402 from the ring 101. The gas in the first airbag 301 and the second airbag 303 will flow out through the exhaust component. When the second airbag 303 contracts synchronously, it will cause the seam-absorbing end plate 305 to separate from the flange 203. At this time, tighten the bolt 204 to remove the flange 203 from the groove 102 until the pre-tightening component is completely removed from the ring 101.
