Problems solved by technology

[0004] However, the tread of most of the current snow tires is formed by one or more large blocks, and the fine grooves on the large blocks really enhance the driving and braking performance of the tire. However, due to the large blocks It is distributed in strips, which leads to poor lateral balance of tires and often side slips

Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] The invention discloses a snow tire to improve the lateral balance performance of the tire. Such as figure 1 with figure 2 The snow tire shown includes a tread, a sidewall and a bead, the sidewall connects the tread and the bead, and the tread is provided with pattern blocks 1 arranged in a staggered manner. The groove 2 and the pattern block 1 are N-gon, N≧5, and the pattern block 1 is provided with fine grooves 11 .

[0029] The tread is provided ...

Abstract

The embodiment of the invention discloses a snow tire which comprises a tire surface, a tire side and a tire ring, wherein the tire side is connected with the tire surface and the tire ring, the tire surface is provided with pattern blocks which are staggered with one another, main grooves are formed among the staggered pattern blocks, the pattern blocks are N-edge blocks, N is an integer which is not less than 5, and the pattern blocks are provided with fine pattern grooves. The tire surface is provided with the N-edge pattern blocks, and the pattern blocks are provided with the fine pattern grooves, the shearing force and the friction force between the snow tire and the road are improved, and then the steering performance, the brake performance and the drive performance of the snow tire are enhanced; because the pattern blocks which are staggered and arranged on the surface of the tire, compared with the strip shaped distribution in the prior art, for the snow tire, the road holding force is enhanced, the lateral shearing force is stronger, the lateral balance performance of the tire is improved, and the lateral sliding of the tire is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of tires, and more specifically relates to a snow tire. Background technique [0002] When the car is running, the main consideration is safety, and safety includes the safety of tires, especially the safety of tires on ice and snow roads. The tire is composed of tread, sidewall and bead. The tread is the part that is in contact with the road surface and protects the carcass; the sidewall is the part that protects the carcass from the edges on both sides of the tread to the rim contact part; The part that makes physical contact and secures the tire to the rim. [0003] Ordinary tires will basically lose their driving ability on icy and snowy roads, bringing unsafe hidden dangers. Therefore, snow tires came into being. There are many fine grooves on the large pattern blocks of snow tires. These fine grooves can increase the shear force and friction between the tire and the road surface. It is these additio...
