Description

Novel pneumatic tire capable of being deflated

Technical Field

The utility model belongs to the field of tires, and particularly relates to a novel pneumatic tire capable of being deflated.

Background

The pneumatic tires in the current market are of two types, one is an inner tire and outer tire structure, and the other is a vacuum tire (without an inner tire) structure. The vacuum tire is not easy to burst, so that the share of the vacuum tire on the market is larger and larger. The existing vacuum tire has three defects: 1. the vacuum tire must be fitted with a special rim. 2. After the vacuum tire is assembled on the rim, the inflation is very difficult, and the trouble is brought to the tire replacement in the later period of maintenance. 3. When the vacuum tire is used, the running is affected once the vacuum tire is deflated. Although some vacuum tires can run for a short distance by increasing the wall thickness of the tire wall in the market when the tire is deflated, the phenomenon of rim knocking over and displacement often occurs when the tire runs under the deflated state, so that the deflated tire still needs to be replaced or repaired in time to be used continuously, and the user is further troubled.

SUMMERY OF THE UTILITY MODEL

In order to solve one or more technical problems in the prior art, the utility model discloses a novel pneumatic tire capable of being deflated, which has a simple structure and high driving comfort, can continuously drive under the condition of deflation of the tire, and cannot damage the tire.

To achieve the above objects, the present invention provides a novel pneumatic tire usable in the air leakage, comprising

The tire body is a closed tubular body, an annular inner cavity is formed in the tire body, the tire body is provided with a clamping part arranged in a wheel rim, and an air inlet nozzle is fixed on the side wall of the clamping part;

the tyre body reinforcing component comprises reinforcing ribs connected in an annular inner cavity of the tyre body, the reinforcing ribs are annularly arranged in the tyre body, and two side edges of the reinforcing ribs are fixedly connected with two inner walls of the tyre body.

Further, the distance between the top of the reinforcing rib and the top wall of the annular inner cavity is one third to one half of the section height of the tire body.

Furthermore, the reinforcing ribs are annular reinforcing ribs and are in the same circle center with the tire body, the number of the annular reinforcing ribs is at least 1, and the annular reinforcing ribs are provided with air holes.

Furthermore, the reinforcing ribs are sheet reinforcing ribs which are uniformly arranged in an annular inner cavity of the tire body in an annular array.

Furthermore, the reinforcing ribs are columnar reinforcing ribs which are uniformly arranged in an annular inner cavity of the tire body in an annular array.

The utility model has the beneficial effects that:

firstly, the tire has a simple structure, and can be well supported and continuously run even in the case of air leakage by arranging the reinforcing ribs;

secondly, compared with a solid tire, the tire is higher in comfort during driving, has good buffering force when encountering a bumpy road section, and can keep comfort and strength as well as the tire because the distance between the top of the reinforcing rib and the top wall of the annular inner cavity is one third to one half of the height of the section of the tire body;

thirdly, the reinforcing ribs can adopt various forms, such as annular reinforcing ribs, sheet reinforcing ribs or columnar reinforcing ribs, and under the condition that the tire is deflated, the strength of the tire body can be kept, the tire is supported to continue walking, and the tire tread can not be extruded by the wheel hub, so that the tire can not be damaged.

Detailed Description

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

referring to FIGS. 1 through 5, a new run-flat pneumatic tire is shown comprising

The tire casing 2 is a closed tubular body, an annular inner cavity 4 is formed in the tire casing 2, the tire casing 2 is provided with a clamping part 3 installed in a rim, an air inlet nozzle 1 is fixed on the side wall of the clamping part 3, and the air inlet nozzle 1 can be inserted into a rim hole of the rim when the tire casing 2 is connected with the rim through the arrangement of the air inlet nozzle 1.

The tyre body reinforcing component comprises reinforcing ribs connected in an annular inner cavity 4 of the tyre body 2, the reinforcing ribs are annularly arranged in the tyre body 2, and two side edges of the reinforcing ribs are fixedly connected with two inner walls of the tyre body 2. Specifically, the tire body reinforcing assembly comprises the reinforcing ribs, two side edges of the reinforcing ribs are fixedly connected to two side walls of the annular inner cavity 4, and by means of the structure, even if the tire body 2 loses air, the reinforcing ribs are connected to the inner wall of the annular inner cavity 4, when the tire body 2 continues to roll, the two side walls of the annular inner cavity 4 cannot be extruded to two sides due to the pulling effect of the reinforcing ribs, so that the ground and a hub can still keep a certain distance, the vehicle still has comfortableness when running, the tire body 2 cannot be further damaged, and the vehicle can run for a long distance.

Further, the distance between the top of the reinforcing rib and the top wall of the annular inner cavity 4 is one third to one half of the section height of the tire carcass 2. Specifically, the distance between the top of the reinforcing rib and the top wall of the annular inner cavity 4 is one third of the height of the section of the tire body 2, and through the arrangement of the distance, the tire body 2 can run under a normal state to ensure good comfort, and can also continue running under an air leakage state, so that the ground of the wheel hub has a certain distance, and the tire is prevented from being further damaged.

In the present invention, the form of the reinforcing rib may be various, in embodiment 1, as shown in fig. 2 and fig. 3, the reinforcing rib is an annular reinforcing rib 6, and is at the same center as the tire carcass 2, the number of the annular reinforcing ribs 6 is at least 1, or may be 2 or more, the annular reinforcing rib 6 is provided with an air hole 8, of course, the number of the annular reinforcing ribs 6 may also be 2 or 3, so that when inflating, the whole tire carcass 2 may be filled with air, and the annular reinforcing rib 6 is provided with an air hole 8.
