Abstract
The utility model discloses a gasket of making an uproar falls in damping, this gasket include aluminium foil, intermediate level and a soft layer, and the intermediate level bonds on the aluminium foil, and a soft layer bonds on the intermediate level, and the intermediate level comprises the 2nd soft layer and the hard formation of mutual bonding, and the 2nd soft layer can bond with a soft layer, and the hard formation bonds on the aluminium foil, and perhaps a hard formation and a soft layer bond, and the 2nd soft layer bonds with the aluminium foil. The utility model discloses effectively reduce vibration frequency, comparatively comfortable sound environment is built to the noise reduction.
Description
Technical field
This utility model is related to a kind of damping noise-reducing pad, specifically one kind be mainly used in automobile brake or its
The damping noise-reducing pad that can reduce noise on his oscillating plate.
Background technology
Automobile engine luggine in braking can produce sound, or other plant equipment also can when vibrating
Produce a certain degree of noise.Some noises are larger, can make one to feel under the weather, in order to reduce noise, it will usually arrange
Miscellaneous part is arranged in corresponding mechanism, so as to reduce noise.In order to reduce vibrating the noise that friction is produced, it will usually in phase
Some cushion films are mounted on the oscillating plate answered, so as to play the low-frequency effect of drop, realizes reducing noise by reducing frequency
Purpose.But current pad noise reduction is not fine, or noise drop do not get off, or low frequency is too strong allows people to feel very
It is uncomfortable.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of damping noise-reducing pad, effectively reduces noise, installation side
Just.
In order to solve above-mentioned technical problem, this utility model takes technical scheme below：
A kind of damping noise-reducing pad, the pad includes aluminium foil, intermediate layer and the first soft formation, and intermediate layer is bonded in aluminium foil
On, the first soft formation bonding is on the intermediate layer.
The intermediate layer is made up of the second soft formation and hard formation being mutually bonded.
Second soft formation is bonding with the first soft formation, and hard formation is bonded on aluminium foil.
The hard formation is bonding with the first soft formation, and the second soft formation is bonded on aluminium foil, and hard formation is installed in the first soft formation and second
Between soft formation.
The intermediate layer is a hard formation, and the hard formation is bonding with the first soft formation, and hard formation and bonding foil.
First soft formation has viscosity.
First soft formation and the second soft formation are made up of macromolecular material.
This utility model is directly mounted on bobbing machine by arranging four-layer structure or three layers of pad using the first soft formation
On structure, vibration is transferred to after the first soft formation and is lowered transmission frequency, then enters one through the second soft formation and hard formation or hard formation again
Step neutralization frequency, had both made frequency not to be lowered to low frequency degree, and noise is effectively reduced again, made acoustic environment make us more relaxing
It is suitable and easy for installation.
Description of the drawings
Accompanying drawing 1 is the side structure schematic view of this utility model embodiment one；
Accompanying drawing 2 is the side structure schematic view of this utility model embodiment two.
Specific embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with the accompanying drawings the utility model will be further described.
As shown in Figure 1, a kind of damping noise-reducing pad, the pad includes aluminium foil 1, intermediate layer and the first soft formation 4, middle
Layer is bonded on aluminium foil, and the first soft formation bonding is on the intermediate layer.First soft formation is directly mounted with the vibrating mechanism for needing noise reduction, is made
Obtain sound transmission and first pass through the first soft formation.
The intermediate layer is made up of the second soft formation 3 and hard formation 2 being mutually bonded.Second soft formation and hard formation have two kinds of arrangements
Mounting means.One kind is that the second soft formation 3 is bonding with the first soft formation 4, and hard formation 2 is bonded on aluminium foil 1, so that whole pad
The structure of the first soft formation 4, the second soft formation 3, hard formation 2 and aluminium foil 1 is followed successively by from top to bottom, as shown in Figure 1.Another be by
Hard formation 2 is bonding with the first soft formation 4, and the second soft formation 3 is bonded on aluminium foil 1, so that whole pad is followed successively by from top to bottom the
One soft formation 4, hard formation 2, the second soft formation 3 and aluminium foil 1, as shown in Figure 2.
Additionally, the intermediate layer can also only include a hard formation for a hard formation, i.e. intermediate layer, the hard formation is simultaneously with first
Soft formation and bonding foil are fixed, i.e., hard formation is installed between the first soft formation and aluminium foil.
In addition, the first soft formation has viscosity, it is convenient that bonding is installed.First soft formation and the second soft formation are by macromolecular material system
Into.
In this utility model, the first soft formation is bonding with vibrating mechanism, and vibration is first delivered to the first soft formation, through the first soft formation
When frequency is reduced by first soft formation so that lower noise.Then again through hard formation, or the second soft formation is followed by, so as to enter
Being neutralized to frequency for one step, has both made sound frequency too low, it is to avoid low frequency occurrence, noise is effectively reduced again.
It should be noted that the above is not to restriction of the present utility model, without departing from wound of the present utility model
On the premise of making design, any obvious replacement is within protection domain of the present utility model.
Claims (3)
1. a kind of damping noise-reducing pad, it is characterised in that the pad includes aluminium foil, intermediate layer and the first soft formation, intermediate layer is glued
