A tire pattern and high-performance radial car tire based on bionic non-smooth structure

Abstract

The invention provides a tire pattern based on a bionic non-smooth structure and a high-performance radial car tire. The tire pattern includes 4 longitudinal grooves, the depth of the longitudinal grooves is 8-10 mm, and the width is 6-8 mm. The sidewalls of the longitudinal grooves form an included angle of 5° to 10° with the radial plane of the tire, and the sidewalls have streamlined pattern grooves whose cross-section is continuously arranged along the tire circumferential direction. The arc length in the axial direction of the tire is 6° / 360°×L, where L is the circumference of the tire outer ring, and the height of the streamlined pattern groove is 20 to 30% of the depth of the longitudinal groove, and the streamlined pattern groove is the largest The depth is 5-10% of the width of the longitudinal groove. The invention can not only reduce the fluid noise generated in the tire tread longitudinal grooves, but also improve the circulation of road surface water in the longitudinal grooves, and improve the gripping force of the tires by increasing the contact area when the tires are worn. .

Description

technical field [0001] The invention belongs to the field of automobile tires, in particular to a tire based on a bionic non-smooth structure and a high-performance radial car tire. Background technique [0002] With the continuous increase of vehicles, traffic noise pollution has affected the normal life of urban residents, and vehicle noise sources are an important part of traffic noise pollution. When the vehicle reaches a certain speed, tire noise will stand out and occupy a dominant position. In order to limit the size of tire noise, in 2009 the European Union recently promulgated EC661 / 2009 "European Union Vehicle General Safety Driving Certification Requirements" and EC1222 / 2009 "Tire Labels Related to Fuel Efficiency and Other Parameters", which include tire rolling resistance, wet road surface Specific requirements were put forward for grip performance and road passing noise, and the tire labeling requirements for tire wet road grip performance level and noise leve...

There have been published patents "201310560419.8", "201210342761.6", "US6866076B2" invention patents. Although the bionic non-smooth structure is used to improve tire noise and water skiing performance, this bionic pattern design cannot guarantee that the tire will not sacrifice the grip ability after wear , because this pattern design method is difficult to ensure that the contact area continues to increase
