Winter tire which adopts tread pattern block of tunneling blade set

Abstract

The invention provides a winter tire which adopts a tread pattern block of a tunneling blade set, which includes crown and shoulder; the crown comprises a first circumferential main groove, a second circumferential main groove, a third circumferential main groove, a fourth circumferential main groove and a fifth circumferential main groove arranged in sequence from an outer side of the tire to aninner side of the tire, and a plurality of transverse grooves arranged circumferentially along the tread; the first circumferential main groove, the second circumferential main groove, the third circumferential main groove, the fourth circumferential main groove and the fifth circumferential main groove define a first pattern block, a second pattern block, a third pattern block, a fourth pattern block, a fifth pattern block and a sixth pattern block in conjunction with the transverse grooves respectively; The pattern blocks and steel plate grooves can improve the grip of a snow tire, the contour design can ensure the largest ground contact, pattern joints and the steel plate grooves can reduce noise so as to achieve low noise, and then the winter tire has a strong ground grip force and good safety performance, and can effectively improve the driving safety in rain and snow weather.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a winter tire using a tread pattern block of a driving blade group. Background technique [0002] At present, when the car is running when the ground is frozen in ice and snow, in order to prevent the road surface from slipping, it is necessary to wear anti-skid chains on the tires to ensure safer driving. However, not every car will carry anti-skid chains with the car, and it is impossible to predict whether there will be ice or snow on the road surface with complete accuracy. Therefore, when running into ice and snow roads suddenly while driving, drivers often feel helpless. [0003] The grip of the tire is the micro-slip between the tire and the road surface when the car starts, brakes, accelerates, and turns, generating friction. Snow tires generate mutual friction through the snow and ice cutting between the tread and the ground. , thereby generating grip performance, so t...

Problems solved by technology

[0003] The grip of the tire is the micro-slip between the tire and the road surface when the car starts, brakes, accelerates, and turns, generating friction. Snow tires generate mutual friction through the snow and ice cutting between the tread and the ground. , so as to produce grip performance, so the grip of snow tires is mainly realized by the tread, while the winter tires in the prior art have simple structure and unsatisfactory anti-skid effect
