Abstract

The utility model provides a tire pattern structure of snowfield engineering machinery. The tire pattern structure comprises a pattern block, pattern block steel pieces and a pattern groove, wherein the longitudinal section and/or cross section of each pattern block steel piece is of a broken-line structure; a great quantity of pattern block steel pieces are arranged on the pattern block, and the longitudinal section of each pattern block steel piece is set as a broken-line structure; due to the design, the structure is constantly opened and closed when running on an ice snow-covered pavement so as to feed the touched ice and snow into the grooves of the pattern block steel pieces, thereby increasing the contact area of the pattern block, improving the traction force and guaranteeing the tread stability; moreover, the structure can effectively grab the ground to prevent slip, thereby improving the running stability of a tire in an ice snow environment and avoiding the problem of slip on an ice snow-covered pavement; moreover, by combining slip resistance and stone removal self-cleaning, the running stability and service life of the tire in the ice snow environment are effectively improved.

Description

Tread structure of snow construction machinery tires

technical field

The utility model relates to a tire pattern structure, in particular to a special tire pattern structure for snow field engineering machinery vehicles.

Background technique

For markets such as Europe and the United States with distinct seasons and relatively many ice and snow seasons, the demand for tires also varies significantly with seasonal changes. Vehicles of the same model and the same purpose will choose different tires for matching in different seasons, and tires for this purpose have emerged as the times require.

At present, the tire tread structure specially designed for snow construction machinery is still blank. For such types of snow construction machinery models, ordinary tires are generally selected for use, so that when driving on ice and snow roads in winter, there will be slippage caused by low driving force In cold environment, the rubber material becomes hard and brittle and cracks appear, which leads to the reduction of tire life and poor safety, which seriously affects the normal service life of tires.

Utility model content

Aiming at the existing problems and deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a tire pattern structure for snow construction machinery, which combines anti-slip and self-cleaning stone removal, effectively improving the driving stability and stability of the tire in the ice and snow environment. life.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is that the tire pattern structure of snow field engineering machinery includes pattern blocks, pattern block steel sheets and pattern grooves, and the longitudinal section and/or cross section of the pattern block steel sheets are Polyline structure.

In the tire tread structure of the above-mentioned snow field engineering machinery, anti-stone protrusions are arranged in the tread grooves.

In the tire tread structure of the above-mentioned snow field engineering machinery, the anti-stone protrusion is a cylindrical structure with a height of 3 mm.

In the tire pattern structure of the above-mentioned snow field engineering machinery, reinforcing ribs are arranged between the pattern blocks.

In the tire pattern structure of the above-mentioned snow field engineering machinery, the height of the reinforcing rib is lower than that of the pattern block.

In the tire pattern structure of the above-mentioned snow field engineering machinery, a snow field indicator mark is arranged under the pattern block of the tire shoulder.

The utility model has the following advantages and beneficial technical effects:

1. The pattern structure of the snow construction machinery tire of the present utility model has a large number of pattern block steel sheets arranged on the pattern blocks, and the longitudinal section of the pattern block steel sheets is set as a broken line structure. This design will not break when driving on ice and snow roads. It will bite the ice and snow that come into contact with the grooves of the pattern block steel sheets, increasing the contact area of the pattern blocks, thereby improving the traction, ensuring the stability of the tread, and effectively gripping the ground and preventing slipping, improving The driving stability of the tire in the ice and snow environment can avoid the problem of slipping on the ice and snow road. the

2. The tire pattern structure of the snow construction machinery of the present invention adds anti-stone protrusions at the bottom of the pattern groove, which improves the anti-stab ability of the construction machinery used in the mining area at the bottom of the groove.

3. In the tread pattern structure of the snow construction machinery tire of the present invention, a snow indication mark is set under the pattern block on the tire shoulder, which is convenient for identifying the type of tire. Compared with the previous design of setting the snow indicator mark above the pattern block, it is more beautiful, and it can effectively avoid the situation that it is difficult to identify after the tire is worn.

Detailed ways

As shown in the figure, the pattern structure of the snow construction machinery tire in this embodiment includes pattern blocks 1, pattern block steel sheets 2 and pattern grooves 3, and the longitudinal section and cross section of the pattern block steel sheets 3 are all zigzag structures. Or one of the longitudinal section and the cross section is a zigzag structure; the anti-stone protrusion 4 is arranged in the pattern groove 3; the anti-stone protrusion 4 is a cylindrical structure with a height of 3mm; the reinforcing rib 6 is arranged between the pattern blocks 1; the reinforcing rib 6 The height of the tire is lower than that of the pattern block 1; a snow indication mark 5 is set under the pattern block 1 of the tire shoulder.

The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model in other forms. Any skilled person who is familiar with this profession may use the technical content disclosed above to change or remodel it into an equivalent change. Equivalent embodiment. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the present invention, as long as they do not deviate from the content of the solution of the present invention.
