Abstract

FIELD: transport.

SUBSTANCE: invention relates to tire production, particularly, to tire air tubes. Proposed tire comprises tire proper and inflatable air tube. Said tube consists of separate contact cells. Said cells are composed of long cavities. Length of every cell is not smaller than that of tube inner surface generatrix in cross-section. Separate pressure feed line runs to every cell. Every cell comprises check valve and separate outlet to the main nipple. Every cell can be located radially in spiral relative to outer limiting outline wherein said cells are located. Cell cavities can be swirled at an angle to each other.

EFFECT: higher reliability at puncture.

Description

The invention relates to the tire industry, in particular to chambers of pneumatic tires.

Known pneumatic tire containing a tire and an inflatable chamber, consisting of separate cells, in which the inflatable chamber consists of separate contacting cells made in the form of long cavities, each of which is no less than the generatrix of the inner surface of the tire along its longitudinal section, s a separate supply of pressure, each cell made in the form of a cavity, contains a check valve and has an outlet to the main nipple (see Patent FR 2605269 A1, B60C 5/02, 12/20/1988).

A disadvantage of the known design is the low survivability and reliability of the tire as a result of breakdown of one of the sectors, which leads to a deterioration in the traction and coupling characteristics of the tire with the road due to a change in the tire profile as a whole.

The basis of the invention is the task of improving the design of the pneumatic tire to increase its survivability and reliability in the breakdown of one of the sectors by maintaining the tire profile of the wheel.

The problem is solved in that in a pneumatic tire containing a tire and an inflatable chamber, consisting of separate cells, in which the inflatable chamber consists of separate contacting cells made in the form of long cavities, the length of each of which is not less than the generatrix of the inner surface of the tire along its longitudinal section, with a separate supply of pressure, each cell made in the form of a cavity contains a check valve and has an outlet to the main nipple, each cell has its own outlet to g avny nipple arranged spirally in the radial direction relative to the outer bounding contour, wherein these cavities are arranged, the cell may be in the form of cavities, twisted at an angle relative to each other.

Since each cell has its own exit to the main nipple, it is arranged in a spiral in the radial direction relative to the external limiting contour in which these cavities are located, while the cells can be made in the form of cavities twisted at an angle relative to each other, increasing the survivability and reliability of the tire during the breakdown of one of the sectors by maintaining the tire profile of the wheel.

The pneumatic tire according to claim 1, characterized in that the cells made in the form of cavities are twisted at an angle relative to each other.

In FIG. 1 - camera without a tire with a concentric arrangement of cavities, as in the prototype;

in FIG. 2 is a section BB in FIG. one;

in FIG. 3 - chamber with a spiral arrangement of cavities;

in FIG. 4 - tear A, cavity, twisted at an angle to each other.

A pneumatic tire (Fig. 1, Fig. 2) containing a tire (not shown conditionally) and an inflatable chamber 1, consisting of separate cells 2 in contact with each other, made in the form of long cavities. The length of each cell 2 is not less than the length of the generatrix of the inner surface of the chamber 1 along its longitudinal section. Each cell 2 is a separate supply of pressure. Each cell, made in the form of a cavity, contains a check valve 3 and has its own outlet 4 to the main nipple 5. Each cell 2 is arranged in a spiral in the radial direction relative to the external limiting circuit 1 in which these cells are located (Fig. 3). Cells 2 are made in the form of cavities and twisted at an angle relative to each other (Fig. 4).

Pneumatic tire is manufactured and operates as follows.

The inner surface of the tire 1 (Fig. 1, Fig. 2) (the tire is not shown conditionally) is filled with individual cells 2 in contact, made in the form of long cavities, for example, tubular, rectangular, etc., of a closed section or the tire is made by casting with simultaneous formation of its inner cavity of the indicated cells 2. To ensure the assembly of the tire 1, the length of each cell 2 should be at least the length of the generatrix of the inner surface of the tire 1 along its longitudinal section. To ensure autonomous operation of cells 2, each of them is supplied separately with pressure through check valves 3 with their own outputs 4 to the main nipple 5. After creating pressure in the cells 2, they are pressed against the inner surface of the tire 1, and, touching their walls, are pressed to each other. In this case, each cell 2 is arranged in a spiral in the radial direction relative to the external limiting contour of the bus 1 in which these cells 2 are located (Fig. 3). Cells 2, made in the form of cavities, can be twisted at an angle relative to each other (Fig. 4) similar to the implementation of the twisting of the rope. The minimum number of cells 2 is two.

The pressure in each cell 2 is supplied through the nipple 5. In case of damage to the tire 1, only part of the cells is damaged, the rest continue to work due to the autonomous supply of pressure and the presence of a check valve 3 on each cell 2. The pressure in the intact cells 2 remains sufficient to ensure the performance of tire 1 and save her profile.

This solution will improve the survivability and reliability of 1 bus in the breakdown of any of the cells 2.

The options for stacking cells in the tire do not have a significant impact on its towing characteristics.
