Embodiment 1

[0033] In Example 1, the 205 / 55R16 specification (pattern 1) for cars is used as a sample. The dimensions of groove L1, groove L2, groove L3, and groove L4 are the same, specifically b is 9mm and h2 is 7.6mm ; There are 11 noise reduction devices A in pattern groove L1, pattern groove L2, pattern groove L3, and pattern groove L4. The distance between two adjacent noise reduction devices A is X1=148mm, X2=154mm, X3= 160mm, X4=167mm, X5=173mm, X6=179mm, X7=186mm, X8=192mm, X9=198mm, X10=205mm, X11=211mm; Image 6 The arrangement sequence of noise reduction device A in each groove is as follows:

[0035] The noise reduction devices A in the grooves above are all the same in size, specifically:

[0036] The root A1 has a length of 12mm and a width of 2.8mm; the middle A2 has a length of 10mm and a width o...

Embodiment 2

[0038] In Example 2, the 205 / 55R16 specification (pattern 2) for cars is used as the sample. There are 11 noise reduction devices A in groove L1, groove L2, groove L3, and groove L4, two adjacent to each other. The distance between noise reduction device A is X1=148mm, X2=154mm, X3=160mm, X4=167mm, X5=173mm, X6=179mm, X7=186mm, X8=192mm, X9=198mm, X10=205mm, X11=211mm; such as Image 6 The arrangement sequence of noise reduction device A in each groove is as follows:

[0039] Pattern groove L1X8X2X10X7X4X3X11X6X9X5X1 Pattern groove L2X10X4X11X5X8X3X1X9X7X2X6 Pattern groove L3X2X9X3X5X8X4X7X11X6X10X1 Pattern groove L4X9X6X11X3X2X5X7X10X8X4X1

[0040] The dimensions of the groove L1 and the groove L4 are the same, specifically b is 10.4mm and h2 is 7.6mm; the size of the noise reduction device A in the above two grooves is: the length of the root A1 is 12mm, the width is 2.6mm; the length of the middle A2 It is 10mm, the width is 1.3mm, the length of the end A3 is 12mm, and ...

Abstract

The invention relates to a noise reduction tire, and belongs to the field of tires. The noise reduction tire is provided with a tire body, and is characterized in that linear tread grooves are formed in the circumferential direction of the tire surface of the tire body at intervals, wherein noise reduction devices (A) are machined in the tread grooves; each noise reduction device (A) consists of three parts, i.e. a root part (A1), a middle part (A2) and an end part (A3); each noise reduction device (A) is arched on in the circumferential direction of each tread groove of the tire, and is like a part of a cylinder; the middle parts (A2) of the noise reduction devices (A) are arched grooves. According to the noise reduction tire, an air column on a grounded part is divided into two parts, and the lengths of the two parts are changed along with time, so that the resonant frequency of the air column is continuously changed along with time, the bandwidth of sounds is increased, and the pumping sound production of longitudinal grooves are interrupted according to a certain time sequence to further increase the bandwidth to reduce noise.

Description

Technical field [0001] The invention relates to the field of tires, and in detail is a noise reduction tire. Background technique [0002] As we all know: car driving noise is one of the main sources of traffic noise. As the only part of the vehicle in contact with the ground, the noise generated by tires directly affects the comfort of the car. In order to limit tire noise, the European Union recently promulgated EC661 / 2009 "European Automobile General Safety Driving Certification Requirements" and EC1222 / 2009 "Tire Labels Related to Fuel Efficiency and Other Parameters" in 2009. Among them, the rolling resistance of tires and wet roads Specific requirements for performance and road-passing noise were put forward, and the tire label requirements for tire gripping performance levels and noise levels on wet road surfaces were clearly put forward, which will be implemented on July 1, 2012. [0003] The sound mechanism of tires is more complicated, and there are many noise reduction...
