Description
Technical field
The invention belongs to tire art, be specifically related to a kind of low noise pneumatic tire, this tire can reduce the low noise pneumatic tire of the noise caused by empty resonance phenomenon effectively, and effectively can reduce noise when vehicle travels.
Background technology
In recent years, together with the more High Performance of automobile, the various performance requirements of tire are also constantly increased, and on the other hand, in order to realize resources conservation and reduce free air capacity, required the exploitation with fabulous noiseless tire.The empty sonorant caused due to the vibration being filled in the air in blank part is the one of the main reasons producing tire noise.This empty sonorant, is when vehicle travels, vibrate, and this vibration makes the air vibration of tire hollow sectors and produces with the fetus face of the tire of road surface ground connection due to the concavo-convex of road surface.Known in this empty sonorant, as the frequency of the sound that noise can be heard, although different because the size of tire is different, but it is general at about 200 ~ 300Hz, thus, in order to effectively reduce tire noise, the sound level reducing this frequency band is very important.
Along with the development of society and the raising of people's quality of life, people are also more and more higher to the performance requriements of motor tire while development in science and technology, low noise pneumatic tire, are the needs catering to social development, and play a good role to minimizing social pollution.Usually the method effectively reducing cavity resonance sound configures the sound-absorbing part be made up of aerated materialss such as urea-formaldehyde foams on the tire inner peripheral surface of the inner side of fetus face, absorbed the cavity resonance sound produced by the vibration of the filling air in tire cavity portion by this sound-absorbing part.
At present, what the noise method reducing tire had is changed by the gorgeous tire circumferential direction of the section shape of the cavity portion making tire, makes the moment change together with the rotation of wheel of cavity resonance frequency reach sound-absorbing object.The sound-absorbing effect that the interests sound-absorbing part also had produces effectively reduces cavity resonance sound.Although the air-inflation tyre being equiped with tire noise reduction device can reach the object reducing noise, this device makes mass distribution circumferentially become uneven, easily produces the problem of homogeneity deteriorates when running at high speed, aggravation body oscillating.
A kind of low noise pneumatic tire, it is provided with multiple sound-absorbing part be made up of porous material in the mode arranged discontinuously along tire circumferential direction on tire inner peripheral surface.After the air-inflation tyre that how empty material sound-absorbing part is housed is arranged on wheel rim, when air-inflation tyre being unloaded from wheel rim in order to faces such as interchangings of tires, sometimes the front end of the bar of load-unloader of tyre is strongly pressed on the surface being all pressed in how empty material sound-absorbing part.But because the material of aerated materials sound-absorbing part is generally soft, tensile splitting strength is lower, so when the bar of load-unloader of tyre is pressed into, has and hold easily vulnerable problem.In general, flat ratio is little, the air-inflation tyre that tire height is low, and this sound-absorbing part more easily sustains damage.Like this, once there is damage location on the sound-absorbing part of low noise pneumatic tire, stress based on airtyred distortion during tire running is just concentrated in this damage location, so still have final sound-absorbing part to depart from the generation causing the problem that cannot obtain desired sound absorption qualities from tire inner peripheral surface.
