Problems solved by technology

In addition, the cantilever beam-type constrained layer steel plate mainly has radial bending deformation and torsional deformation, and mainly plays a role in tension and compression on the rubber layer, but there is basically no vibration degree of freedom and rubber shear effect along the wheel axis.
Therefore, the technical effect of vibration reduction and noise reduction that this solution can achieve will also be greatly limited, and there is room for further improvement

Embodiment 1

[0039] Embodiment 1: as Figure 1 to Figure 4 Shown, a kind of wheel noise reduction method, it is to arrange multilayer type wheel noise reduction block 2 on the circumferential inner side of wheel 1 to carry out vibration reduction and noise reduction, in multilayer type wheel noise reduction block 2 close to the wheel 1 A mounting plate 3 is arranged on one side of the inner side of the circumference, and a hole 4 and a hole 5 are respectively arranged at both ends of the mounting plate 3, and the two end bolts 6 are screwed through the hole 4 and the hole 5 respectively. Into the circumferential inner side of the wheel 1, so that the two ends of the multi-layer wheel noise reduction block 2 are connected to the wheel 1, and the first outer ring is arranged on the side of the multi-layer wheel noise reduction block 2 near the wheel shaft 7. A constrained layer 8, a suspended inner constrained layer 9 is set between the mounting plate 3 and the first outer constrained layer ...

Embodiment 2

[0053] Embodiment 2: as Figure 5 As shown, compared with Example 1, the difference is that the suspended inner constraining layer 9 is a single-layer structure.

Embodiment 3

[0054] Embodiment 3: as Figure 6 As shown, compared with Embodiment 1, the difference is that an axial extension 101 is provided on the other end of the mandrel 10, so that the other end of the mandrel 10 forms a circular boss shape, and at the first The outer constraining layer 8 is provided with a through hole 14 matching the axial extension 101, and the axial extension 101 is inserted into the through hole 14 to closely fit with the through hole 14, so that one end of the mandrel 10 In contact with the first outer constraining layer 8 . The axial protruding part cooperates with the through hole to play the role of installation and positioning. The mounting plate 3 is provided with a positioning groove 15 matched with one end of the mandrel. When assembling, one end of the mandrel is inserted into the positioning groove and closely matched with the positioning groove, which can further facilitate the installation and positioning of the product. Here, an axial protruding p...

Abstract

The invention discloses a wheel noise reduction method and a multi-layer type wheel noise reduction block. According to the wheel noise reduction method, the multi-layer type wheel noise reduction block is arranged on a wheel for vibration attenuation and noise reduction, a mounting board is arranged in the multi-layer type wheel noise reduction block, a first hole and a second hole are formed inthe two ends of the mounting board correspondingly, and two end portion bolts penetrate through the first hole and the second hole to be screwed onto the wheel; a first outer restraint layer is arranged on the side, close to an axle, of the multi-layer type wheel noise reduction block; a suspension type inner restraint layer is arranged between the mounting board and the first outer restraint layer; a hollow spindle penetrates through the suspension type inner restraint layer, one end of the spindle makes contact with the mounting board, and the other end of the spindle makes contact with thefirst outer restraint layer; the suspension type inner restraint layer is vulcanized and stuck between the mounting board and the first outer restraint layer through a first damping layer; and a middle bolt penetrates through the first outer restraint layer, the spindle and the mounting board and then is screwed into the inner side portion of the circumferential direction of the wheel, and accordingly the middle of the multi-layer type wheel noise reduction block is connected to the wheel.

Description

technical field [0001] The invention relates to a method and device for reducing vibration and noise of a wheel, in particular to a method for reducing noise of a wheel and a multi-layered wheel noise reducing block. Background technique [0002] When the train is running, the wheels roll on the track. Due to the roughness of the surface and the unevenness of the wheel-rail tread, the modal vibration response of the wheel is excited, resulting in strong vibration and structural noise, which are radiated to the air through the wheel surface. If a noise reduction structure or material is installed on the wheel, the purpose of reducing the noise radiation level of the wheel can be achieved by suppressing the energy of the vibration and noise source. [0003] The wheel noise reduction prior art mainly contains following 4 kinds: wheel damper, wheel noise reduction plate, wheel noise reduction ring and elastic wheel. The application publication number is CN106004229A, and the Ch...
