Description
Technical field
The present invention relates to a kind of noise reduction device being additional on the inside of tire and its production methods, belong to Tire production skill
Art field.
Background technique
The existing aerated rubber tyre generally used, high speed scroll operation in meeting and rub road surface between formed it is larger
Noise and influence external environment and interior take environmental amenity.
Through relation technological researching, the reason of generating such rolling noise other than with pavement friction, also as in tire
Chamber gas pressure distribution is unbalanced, and irregular air-flow is formed within the scope of mark when contacting so as to cause tread block and road surface.
Under the joint effect of light weight and tractive force, carcass local subsidence will form when tire enters within the scope of tread footprint,
And when tire is driven out to mark range, carcass local recovery original state, in cycles.In this interphase, because of inside tires cavity volume
It changes with shape and causes cavity vibration obvious, and then change with such cavity volume and form Gas Vibration waveform,
This has resulted in inner cavity flow perturbation and the cavity noise that is formed.
It is directed in the research achievement of pneumatic tire cavity noise at present, finds no proposition and targetedly cut down technical side
Case fails the solution of such tyre noise the main cause and effective means that really solve above-mentioned noise generation.
In view of this, special propose present patent application.
Summary of the invention
Tyre noise cutting device of the present invention and its production method are to solve above-mentioned prior art problem and take
Inside tires install additional have checkerboard layout mute layer structure, with absorb and cut down cause because running at high speed tyre surface with
Road surface contacts the inner air vibration noise to be formed.

When within the scope of mark, by light weight and influence of tractive force, tire local subsidence；When tire is driven out to mark range, tire
Local recovery's original state；It is formed in above-mentioned gap periods and generates cavity vibration wave because of cavity volume variation.Above-mentioned triangle is prominent
The continuous concave-convex channel that 27 are constituted is played on the one hand can by the effect of pressure face and absorbing surface that peaks and troughs are formed
The cavity noise vibration for effectively absorbing and weakening different frequency range, on the other hand can also upset the vibration frequency of cavity noise, from
And avoid the appearance of tire resonance noise.
Between 23, the 4th groups of mute layers 24 of third group mute layer, the farthest longitudinal directions of adjacent 2 pieces of polyurethane foam materials away from
It is 4 centimetres from Le；
In 23, the 4th groups of mute layers 24 of third group mute layer, the longest fore-and-aft distance of adjacent 2 pieces of polyurethane foam materials
Ld is 12 centimetres.
As shown in Figures 1 to 9, the production method of the tyre noise cutting device is to adsorb foam process by whole
And at least one set of mute layer 2 is made, mute layer 2 is bonded in base band 1；
Every group of mute layer 2 is equably arranged along the longitudinal gap of base band 1；
Mute layer 2 is that 2 layers of overlaying structure and every layer are the blown polyurethane materials that adjacent bubbles constitute communicating passage；
On except other end faces Nian Jie with base band 1, it is equably arranged with feather trailing edge shape serration 25；
It will be stained with 1 another side of base band of mute layer 2, the inner circumferential center line of fetus is bonded after vulcanization.
Wherein, after 2 layers of polyurethane foam material superposition of the mute layer 2, docking forms tubulose, just profound wave along longitudinal direction
Shape channel.
The base band 1 is selected made of modified pressure sensitive acrylic adhesive without base material adhesive tape, then assist being constituted with fiber
Double faced adhesive tape；
During the bonding process, fetus inner circumferential center line bonding region is ground to remove mould release, so first
It successively attaches afterwards, be bonded the base band 1 for having mute layer 2.
As shown in Fig. 10 tyre cavity noise testing comparison diagram, tire take the application institute in vehicle travel process
The 2 kinds of mute layer arrangement modes proposed are concentrated compared to without herein described cutting device in the noise frequency of 200Hz or so
Area, cavity noise decline are the most obvious.
To sum up content is only the preferred embodiment for realizing the object of the invention in conjunction with the embodiment provided in attached drawing.For affiliated
