Embodiment Construction

[0024] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-2 As shown, a winter tire with zigzag blocks includes a tread 1, a shoulder 2, and a tire pattern disposed on the tread and the shoulder in the tire circumferential direction, the tire pattern including a main tread located in the center of the tread The radial pattern 10 and the blocks located on both sides of the main radial pattern and forming a sliding symmetry with respect to the center line, the block pattern on either side includes a first main groove that is bent and extended from one side of the main radial pattern to the outer side of the tread 30. A curved block 20 is arranged between any two first main grooves, the side of the curved block facing the centerline has a tip 27, and two sides of the main diameter pattern are arranged along the extension direction of the main diameter pattern. zigzag pattern 11; s...

Abstract

The invention discloses a winter tire with zigzag blocks, comprising a tread, a shoulder, and a tire pattern arranged on the tread and the shoulder along the tire circumferential direction, and the tire pattern includes a main diameter located at the center of the tread The pattern and the block pattern located on both sides of the main diameter pattern and forming a sliding symmetry with respect to the center line, the block pattern on either side includes the first main groove extending from one side of the main diameter pattern to the outside of the tread, and any A curved pattern block is arranged between the two first main grooves, and the curved pattern block has a tip on one side facing the center line, and zigzag patterns arranged along the extending direction of the main diameter pattern are arranged on both sides of the main diameter pattern; The zigzag pattern includes outwardly protruding and zigzag teeth, and inwardly recessed tooth grooves; the tip faces the tooth grooves and is separated from them by a certain distance, and forms a communication with the first main groove between the two The unique snow flow groove, through the optimization of the tread pattern, improves the grip of the tire.

Description

technical field [0001] The invention relates to the field of tires, in particular to a winter tire with a zigzag tread pattern. Background technique [0002] With the vigorous development of the automobile industry and the continuous improvement of people's living standards, the demand for tire performance is becoming more and more stringent, especially the performance requirements of tires on ice, snow and wet roads. The grip of the tire is the friction force generated by the micro-slip between the tire and the road surface when the car starts, accelerates, brakes, and turns. Mutual friction, thus generating grip, so the grip of snow tires mainly comes from the tread; while the tread of snow tires is mainly composed of block blocks and steel sheet patterns, in the case of the same formula, mainly through The tread pattern is designed to improve the grip of snow tires. [0003] The tire profile and structure design can maximize the ground contact area of ​​the tread and th...
