The invention relates to the tire industry, the design of the tread of pneumatic-tired vehicles, including dump trucks, providing a grip with the road surface.

Known the tread of a pneumatic tire, a figure which is made with lugs S-shaped, separated from each other by grooves (tires /C. L. [, R. L. Gosliner, S. P. Zakharov n other M: Goskomizdat. 1963.-S.) For reasons that impede the achievement of specified following technical result when use the nuclear biological chemical (NBC surface.

The closest device to the same destination to the claimed invention on the totality of symptoms is the protector pneumatic Tina, a figure which is made with a wide lug S-shaped with transverse grooves, and the lugs are separated by a narrow grooves (Pneumatic tyres /S. M. Zuckerberg, R. K., Gordon, J. P. Neuenkirchen, C. N. Predict-M.: Chemistry, 1976, 33 p.).

For reasons that impede the achievement of specified following technical result when using the known device, taken as a prototype, is that in the known device is insufficient lateral coupling with the supporting surface. In addition, when the vehicle is on soils with low bearing capacity is sticking grooves.

The invention solves the problem of increasing the adhesion of the tread pneumatic tyres with the road surface.

The technical result, which can be obtained by carrying out the invention, is to improve the adhesion with the road surface and increase smoochies tread.

This technical result in the implementation of the invention is achieved in that in the known the tread of a pneumatic tire is Ruga narrow grooves, the peculiarity lies in the fact that the transverse grooves in the lugs are staggered at a distance of 0.2-0.3 width of the treadmill from the axis of symmetry of the tread, and the lug is made extending to the base.

In the study of the distinctive features described tread pneumatic tyres not revealed any known similar decisions regarding the location of the circumferential grooves.

Conducted by the applicant's analysis of the prior art, including the search but the patent and scientific and technical information sources and identify sources that contain information about the equivalents of the claimed invention, has allowed to establish that the applicant had not discovered similar, characterized by signs, identical with all the essential features of the claimed invention, the definition from the list of identified unique prototype, as the most similar in essential features analogue, has identified a set of essential towards perceived by the applicant to the technical result of the distinctive features in the claimed device, set forth in the claims.

Therefore, the claimed invention meets the condition of "novelty."

The drawings show: Fig.1 shows a tread of a pneumatic tire; Fig.2 is a section along a - a of Fig.3 - section-Century

Information confirming the ability of the invention to provide the above technical result are as follows. The tread of the pneumatic tire contains a wide S-shaped lug 1, spaced from edge to edge of the tread. The lugs are made extending to the base 2 and are separated by a narrow groove 3. In the groove 3 along the axis of symmetry executed polymastia 4. At a distance of 0.2-0.3 width of the treadmill from the axis of symmetry in the lugs staggered cross made Kanamori at an angle of 15oand rounded with a radius of 10 mm (Fig.3).

The design of the figure was worked out experimentally. It was found that the values of some design parameters are optimum, which gives the greatest effect. These optimal and close to them the values of the parameters are input in the design of the signs.

The transverse grooves 5 are situated in the most optimal location tread, as in the case of offset them less or more than 0.2 to 0.3 width of the tread from the axis of symmetry they will be the least efficient of the tread and do not provide lateral stability. A shorter distance will lead to a decrease in shoulder location district grooves and, therefore, reduce the effectiveness of side-chaining. The increase of the distance, although increases shoulder location district grooves, but reduces the area of the lug 1, resulting in the deformation direction, movement of the bus, cracks may appear at the base of the lug.

The choice of the depth of the grooves due to the fact that at lower depth in the operation of the bus and the natural deterioration of the figure, the groove depth of less than 80% of the total depth of the picture pratali CSM, when the tires down the residual tread depth is 80%.

Chess arrangement of the grooves 5 is selected because during normal circuit arrangement reduces the area of contact of the tyre with the road due to decrease saturation. In the proposed version achieved the minimum reduction of the area of the treadmill and increase lateral stability.

The walls of the grooves 5 are angled 15oto facilitate extraction of the tire from the mold and to improve smoochies grooves, the transition from the walls to the bottom of the grooves are rounded with a radius of 10 mm to reduce stress concentrations at the bend of the treadmill and to prevent the formation of cracks in the grooves of the tread.

The proposed design of the tread pattern with Vvedenie additional district kanasaki, staggered in the lug, significantly improves lateral stability and traction when driving a vehicle on soils with low bearing capacity, in addition, with this design protector more grooves allow to increase semiochemistry picture at all stages of wear and tear.

Formula izopet the slow grooves, wherein the transverse grooves in the lugs are staggered at a distance of 0.2-0.3 width of the treadmill from the axis of symmetry and at a depth of 100-80% of the tread depth, and the lug is made extending to the base.
