Embodiment Construction

[0019] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Such as figure 1 As shown, a snow tire for improving ice and snow performance includes a tread 1, on which there are transverse grooves 2 extending along the tire transverse direction and main grooves 2 extending along the tire circumferential direction on the central axis of the tread circumferential direction. Groove 3, the transverse grooves are provided with multiple equidistant sequentially in the circumferential direction of the tire, a plurality of pattern blocks 4 divided by several transverse grooves and the main groove 3, the pattern blocks 4 are centered on the tread circumferential axis in the tread The left and right sides are symmetrically staggered. The staggered distance a of the pattern blocks on the left and right sides of the central axis of the tread 1 is 1 / 2 of the circumferential length b of the pattern blocks. Th...

Abstract

The invention provides a snowfield tire capable of improving the performance of ice and snow fields. The snowfield tire comprises a tread, wherein the tread is composed of a plurality of decorative pattern blocks which are crossly divided through a plurality of transverse grooves and main grooves which are formed in the peripheral middle axis of the tread and extend along the peripheral directionof the tire; the decorative pattern blocks are symmetrically arranged at the left an right sides of the tread on the peripheral middle axis of the tread in a staggered manner; each decorative patternblock is provided with a tire shoulder groove with the inclined angle of 6 to 12 degrees, a secondary groove I with the inclined angle of 5 to 9 degrees and a secondary groove II with the inclined angle of 24 to 30 degrees in sequence from outside to inside; a decorative pattern block I is limited between each tire shoulder groove and the corresponding secondary groove I; a decorative pattern block II is limited between each secondary groove I and the corresponding secondary groove II; a decorative pattern block III is limited between each secondary groove II and the corresponding main groove;and each secondary groove I is internally provided with a rubber convex block. According to the snowfield tire, a tread decorative pattern structures is improved, so that the gripping force of the tire on the ice and snow fields, the trafficability on the ice and snow fields and the manipulation performance are improved; and meanwhile, noise can be reduced.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a snow tire for improving performance on ice and snow. Background technique [0002] With the vigorous development of the automobile industry and the continuous improvement of people's living standards, the requirements for tire performance are becoming more and more stringent, especially the performance requirements for tires on ice and snow roads. The grip of the tire is the micro-slip between the tire and the road surface when the car is running, which generates friction. The snow tire generates mutual friction through the action of cutting snow and ice between the tread and the ground, thereby generating grip. The grip of the tire mainly comes from the tread, and the tread of the snow tire is mainly composed of block pattern blocks and small sipes. Improve the grip of snow tires on ice and snow. Existing snow tires have insufficient grip on ice and snow, and cannot combine lo...
