Abstract
The invention discloses a pneumatic tire with a noise reduction device. The pneumatic tire comprises a wheel rim and a tire arranged on the wheel rim, wherein a noise reduction device is arranged in an annular cavity formed between the wheel rim and the tire and comprises an elastic circular ring which sleeves the periphery of the wheel rim and a plurality of elastic rectifying screens which are circumferentially and uniformly distributed on the peripheral surface of the elastic circular ring. By adopting the pneumatic tire disclosed by the invention, noises caused by sound resonance of the tire cavity can be effectively reduced, and the NVH performance of vehicles can be improved.
Description
Technical field
The present invention relates to vehicle part, be specially a kind of air-inflation tyre with denoising device.
Background technology
At present, the noise caused along with dynamic assembly constantly reduces, and the proportion that tire is made an uproar and wind is made an uproar to be accounted in auto NVH is increasing.When middle low speed driving, squeal of tire occupies maximum proportion.So the squeal of tire level of automobile has also reacted the NVH level of a car entirety at present.
The driving source that tire is made an uproar as tire, the tire that the NVH level of tire directly determines vehicle is made an uproar level.Because tire cavity is as a closed cavity, it has oneself natural frequency (cavity mode).When vehicle is by rough road and band horizontal strip excitation road traveling, due to the shock-excitation effect of road roughness, tire cavity mode is energized the sound wave of formation resonance.The frequency of tire cavity sympathetic response is mainly at 200-300Hz, and frequency depends primarily on tire size.
Due to the build-in attribute that tire cavity mode is tire, be optimized so mainly concentrate in bang path and vehicle body response for the optimization of tire cavity resonance noise, namely optimize suspension vibration isolation and vehicle body sensitivity.But above-mentioned optimization means deposits defect both ways: be optimize suspension vibration isolation to bring impact to vehicle operating stability on the one hand, need to do comparatively comprehensively to assess, optimization cycle is long, and rectification parts are many.On the other hand, for vehicle body sensitivity optimization, same optimization cycle is longer, and rectification parts are many, and difficulty is large.
CN200980103334.9 discloses a kind of tire with denoiser, and it, by arranging sponge material in tire circumferential direction, suppresses cavity resonance.But the processing of this sponge material and assembling all more complicated.
Summary of the invention
The object of the present invention is to provide a kind of air-inflation tyre with denoising device, to reach the effect improving tire cavity sympathetic response.
The air-inflation tyre with denoising device of the present invention, comprise wheel rim and be arranged on the tire on wheel rim, be provided with denoising device in the toroidal cavity formed between described wheel rim and tire, described denoising device comprises the elastic circular ring and the circumferential polylith elasticity rectifier cubice be distributed on elastic circular ring outer peripheral face that are set in wheel rim periphery.
Described elastic circular ring and elasticity rectifier cubice adopt flexible material one-body molded.
Described elasticity rectifier cubice offers via hole.
Beneficial effect of the present invention is: the elasticity rectifier cubice of this tire denoising device has and improves air vibration in cavity, tire cavity acoustic resonance is played to the effect better increasing damping simultaneously.Therefore, effectively can reduce the noise caused by tire cavity acoustic resonance, improve vehicle NVH performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of described denoising device;
Fig. 3 is the present invention and existing airtyred contrast test schematic diagram.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further elaborated, and following examples only for explaining the present invention, do not form limiting the scope of the present invention.
The air-inflation tyre with denoising device as shown in Figure 1 and Figure 2, the tire 3 comprising wheel rim 2 and be arranged on wheel rim, forms an airtight toroidal cavity between described wheel rim and tire.Denoising device 1 is provided with in described toroidal cavity, described denoising device 1 comprises the elastic circular ring 101 and the circumferential polylith elasticity rectifier cubice 102 be distributed on elastic circular ring outer peripheral face that are set in wheel rim periphery, and described elastic circular ring 101 and elasticity rectifier cubice 102 adopt quality of rubber materials one-body molded.Because elastic circular ring has larger deflection, more easily can be enclosed within wheel rim periphery, and can closely cooperate with it, ensure that wheel is in rotary course, elastic circular ring rotates together with wheel rim.
The quality of each elasticity rectifier cubice 102 described is identical with shape, and lighter weight, therefore very little for tire motion balance influence.Further, the conveniently installation of tire and wheel rim, described elasticity rectifier cubice is offered via hole (not shown in FIG.), makes elasticity rectifier cubice can be good at distortion and steps down.
Elasticity rectifier cubice 102 due to this tire denoising device 1 has and improves air vibration in cavity, tire cavity acoustic resonance is played to the effect better increasing damping simultaneously.Therefore, the noise of frequency limit roughly caused by the tire cavity acoustic resonance of 200 ~ 300Hz can effectively be reduced.
Fig. 3 represents that certain car adopts existing common air-inflation tyre, has installed the air-inflation tyre internal car noise spectral change schematic diagram of denoising device of the present invention with employing.Visible, when having installed the air-inflation tyre operation of Tire noise reducing device of the present invention, the 235Hz noise caused by tire cavity sympathetic response has had obvious improvement.In Fig. 3, solid line represents internal car noise spectrum line when not adopting the air-inflation tyre of this denoising device to run, internal car noise spectrum line when dotted line represents that the air-inflation tyre that have employed this denoising device runs.
