Embodiment Construction

[0028] Below in conjunction with specific embodiment, content of the present invention is described in further detail: in order to achieve the purpose of the present invention, figure 1 , figure 2 A three-dimensional schematic diagram and a partial expanded schematic diagram of the snow tire in an embodiment of the present invention are respectively shown. The snow tire is composed of several parts such as a tire body, a cord layer, a belt layer and a tread 1 . Among them, the tire body needs to have sufficient strength and elasticity to withstand strong vibration and impact, and to withstand multiple deformations caused by the radial, lateral, and circumferential forces of the tire during driving; the ply is the stressed skeleton layer of the tire. To ensure that the tire has the necessary strength and dimensional stability; the belt layer is used to buffer the external impact, protect the tire body, and enhance the adhesion between the tread 1 and the ply; the tread 1 is u...

Abstract

The invention relates to a snow tire. The snow tire comprises a tire body, a cord ply, a belt ply and a tread; at least four longitudinal grooves, which extend in the circumferential direction of thetire body, are formed in the tread; the number of the longitudinal grooves is an even number; and the longitudinal grooves are symmetrically formed relative to the center line of the thread and are shaped like broken lines. Therefore, the cut-in capacity of the tire is improved so that the anti-skid performance on snow is improved and the operability is enhanced. In addition, as the widths and bending angles of the two longitudinal grooves close to the center line of the tread are smaller than those of the rest longitudinal grooves, the middle position of the tread realizes better guidance quality; and as the tread of an area close to the external side realizes larger ground grip force, the side slip prevention performance is improved.

Description

technical field [0001] The invention relates to an automobile tire, in particular to a snow tire. Background technique [0002] In developed countries in northern Europe, driven by consumption concepts and habits, the number of snow trailers is very large, so the consumption of snow trailer tires is relatively large. Due to climatic factors, the cold weather in the Nordic countries is relatively long in a year. In order to ensure safe driving on the road, the tires must be replaced with snow tires. Similarly, the non-drive tires of trailers mainly used for cargo must also be replaced with snow tires. Safe on the road. The existing snow tires on the market have problems such as poor anti-skid ability, poor handling performance, and high fuel consumption, which need to be solved urgently. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a snow tire, which has better maneuverability, skid re...
