Embodiment 1

[0021] Such as Figure 1 to Figure 2 Shown, as a preferred embodiment, this embodiment provides a kind of snow tire, comprises tire body and tread, and tread comprises tread crown 10, tire shoulder 8 and sidewall 11, and tread crown 10 is arranged on tire body and is connected with In contact with the ground, the shoulder 8 connects the crown 10 and the sidewall 11. The crown 10 is composed of four longitudinal grooves 2 arranged in the circumferential direction of the tire body and several transverse grooves 3 arranged in the width direction of the tire body. Four rows are formed. A pattern block sequence, each pattern block of the pattern block sequence is provided with fine grooves.

[0022] The four-row pattern block sequence provided in this embodiment is pentagonal pattern block sequence 1, square pattern block sequence 4, rhombus pattern block sequence 5 and parallelogram pattern block sequence 6; among them, the square pattern block sequence 4 The length is 22 mm and ...

Embodiment 2

[0026] As the second preferred embodiment, the rest is the same as that of Embodiment 1, except that the sequence of four rows of pattern blocks provided in this embodiment is sequence 1 of hexagonal blocks, sequence 4 of rectangular blocks, sequence 5 of diamond blocks and Parallelogram block sequence 6; rectangular block sequence 4 has a rectangular block length of 20 mm and a width of 28 mm, diamond block sequence 5 has a rhombus block length of 30 mm and a width of 31 mm, parallelogram block sequence 6 has parallel The length of the quadrilateral pattern block is 20 mm, and the width is 28 mm. The arrangement and size of the sequence of four rows of pattern blocks can achieve the best effect.

[0027] The groove width of the longitudinal groove 2 provided in this embodiment is 10mm, and the groove depth is 10mm; the groove depth of the transverse groove 3 is greater than the groove depth of the longitudinal groove 2, and its groove depth is 11mm; Parallel to the horizontal...

Embodiment 3

[0029] As the third preferred embodiment, the rest is the same as Embodiment 1 or 2, the difference is that the sequence of four rows of pattern blocks provided in this embodiment is octagonal pattern block sequence 1, rectangular pattern block sequence 4, rhombus pattern block sequence 5 and parallelogram block sequence 6; rectangular block sequence 4 has a rectangular block length of 25 mm and a width of 26 mm, diamond block sequence 5 has a diamond block length of 28 mm and a width of 30 mm, and parallelogram block sequence 6 The length of the parallelogram pattern block is 25 mm, the width is 26 mm, and the arrangement and size of the sequence of four rows of pattern blocks can achieve the best effect.

[0030] The groove width of the longitudinal groove 2 provided in this embodiment is 8mm, and the groove depth is 9mm; the groove depth of the transverse groove 3 is greater than the groove depth of the longitudinal groove 2, and its groove depth is 10mm; Parallel to the ho...

Abstract

The invention relates to a snowfield tire. The snowfield tire comprises a tire body and a tread, wherein the tread comprises a crown, a tire shoulder and tire sidewalls, wherein the crown is arranged on the tire body and contacted with the ground, the tire shoulder is connected with the crown and the tire sidewalls, the crown is formed by a plurality of longitudinal grooves which are formed along the circumferential direction of the tire body and a plurality of transverse grooves which are formed along the width direction of the tire body, the longitudinal grooves and the transverse grooves are intersected to form a plurality of rows of pattern block sequences, the multiple rows of pattern block sequences include at least one of a polygonal pattern block sequence and a parallelogram pattern block sequence, and each pattern block of the multiple rows of pattern block sequences is provided with a fine-grained groove. The crown is provided with a plurality of rows of pattern block sequences, the multiple rows of pattern block sequences are formed by combining the polygonal pattern block sequences and the parallelogram pattern block sequences, by adopting the parallelogram pattern block sequences, the tire can be relatively easily embedded into a snowfield pavement, so that the traction capacity of the tire in a snowfield pavement can be improved, and powerful driving force can be played, and the safety running on the snowfield pavement can be realized.

Description

technical field [0001] The invention relates to a tire, in particular 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 snowy roads. The tire is composed of the tire body and the tread. The tread includes the crown, the shoulder and the sidewall. The crown is the part that contacts the road surface and protects the main body of the tire; the shoulder connects the crown and the sidewall; the sidewall is the part that is in contact with the tire body. And fix the tire to the part on the tire main body. The main functions of tires are to transmit driving force, change driving direction, buffer vibration and bear weight, etc., and the safety performance of tires depends to a large extent on its grip and stability. [0003] At present, most of the tires on the market are mainly to meet the most basic requirements for tires put forward by automobiles,...
