Description

Hollow composite tire structure

Technical Field

The invention relates to the technical field of wheel structures, in particular to a hollow composite tire structure.

Background

The tire is divided into a pneumatic tire and a non-pneumatic tire, and is widely used in view of the fact that the conventional pneumatic tire is mature in production process, good in riding comfort and good in bearing capacity due to cushioning. However, as a large number of vehicle driving safety accidents are more and more caused by tire burst, abrasion and unstable running, the inflation-free tire has no inner tube, and the inflation-free tire has the advantages of high safety, energy conservation, environmental protection and the like, so that people pay more attention to the tire. The non-pneumatic tire is generally a solid tire, but the solid tire has the problem of poor damping effect through observation.

In view of the above, the present disclosure is developed by the present designer aiming at the above disadvantages and inconveniences.

Disclosure of Invention

Aiming at the problems in the prior art, the invention aims to provide a hollow composite tire structure with good damping effect.

In order to achieve the purpose, the invention adopts the technical scheme that:

a hollow composite tire structure comprises an outer tire, wherein the outer tire is provided with at least one first chamber and one second chamber, and the first chamber is arranged along the circumferential direction of the outer tire; the second chamber is also disposed along the circumference of the tire casing and has an inwardly facing opening.

An inner tube is arranged in the second chamber.

The inner tube is a solid tire.

The inner tube is provided with a plurality of third chambers, and the third chambers are arranged along the radial direction of the inner tube.

The third chamber has an opening facing away from the outer tire.

The outer tire and the inner tire are made of the same or different materials.

The hardness of the inner tube is greater than that of the outer tube.

The cover tire includes the tread and connects the side wall at tread both ends, be equipped with the draw-in groove on the side wall, correspondingly, the inner tube of a tyre periphery is equipped with the boss with the draw-in groove block.

And a groove is arranged on the tread of the outer tire.

After the scheme is adopted, the first chamber and the second chamber are formed on the outer tire, so that the deformation space of the outer tire is increased, and the damping effect of the outer tire is further improved.

In addition, an inner tube is additionally arranged in the second cavity of the outer tire, so that the supporting strength of the hollow composite tire can be improved. Furthermore, a third chamber arranged along the radial direction of the inner tube is additionally arranged on the inner tube, so that the hollow composite tire has a better shock absorption effect on the basis of better supporting strength, the third chamber can also improve the heat dissipation effect of the inner tube, and the service life of the inner tube is prolonged.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

The invention discloses a hollow composite tire structure with a good damping effect, and in order to elaborate the technical scheme and the technical effect to be achieved, three embodiments are listed for description.

Example one

As shown in fig. 1, the hollow composite tire structure of the present embodiment includes a tire casing 100, wherein a first chamber 110 and a second chamber 120 are disposed on the tire casing 100, and the first chamber 110 is a sealed chamber and is disposed along the circumferential direction of the tire casing 100; the second chamber 120 is also disposed along the circumference of the tire casing 100 and has an inwardly facing opening.

In this embodiment, the first chamber 110 and the second chamber 120 are disposed on the tire casing 100, so that the tire casing 100 has a larger deformation space, thereby achieving the purpose of good damping effect.

The casing 100 includes a tread 130 and sidewalls 140 connected to both ends of the tread 130. To improve the anti-skid performance of the casing 100, grooves 131 may be provided in the tread 130 of the casing 100.

Example two

As shown in fig. 2 and 3, the present embodiment is further improved on the basis of the first embodiment, specifically, an inner tube 200 is disposed in the second chamber 120 of the tire casing 100, and the inner tube 200 is of a solid structure.

In this embodiment, the support strength of the hollow composite tire can be enhanced by the arrangement of the inner tube 200, so that the hollow composite tire can have the beneficial effects of good shock absorption effect and good support strength.

In order to enhance the stability of the connection between the outer tire 100 and the inner tire 200, a clamping groove 141 is provided on the sidewall 140, and correspondingly, a boss 220 engaged with the clamping groove 141 is provided on the outer circumference of the inner tire 200.

The inner tube 200 and the outer tube 100 of the hollow composite tire can be made of the same material; different materials may be used, wherein the inner tube 200 has a greater stiffness than the outer tire 100 to provide better support.

EXAMPLE III

As shown in fig. 4 and 5, this embodiment is an improvement of the two pairs of the above embodiments, and unlike the second embodiment, the inner tube 200 is a non-solid tire, and a third chamber 210 is disposed on the inner tube 200, and the third chamber 210 is disposed along the radial direction of the inner tube 200. And the third chamber 210 has an opening facing away from the tire casing 100.

Compared with the second embodiment, the third chamber 210 can further improve the shock absorption effect, and simultaneously improve the heat dissipation performance of the inner tube 200, so that the performance of the inner tube 200 is better; furthermore, the first chamber 110 is matched to avoid the jumping problem caused by the third chamber 210.

One or more first chambers 110 may be provided.

In summary, the key point of the present invention is that the first chamber 110 and the second chamber 120 are formed on the tire casing 100 to increase the deformation space of the tire casing 100, so as to improve the shock absorption effect of the tire casing 100.

In addition, the support strength of the hollow composite tire can be improved by additionally providing the inner tube 200 in the second chamber 120 of the outer tire 100. Furthermore, the third chamber 210 arranged along the radial direction of the inner tube 200 is additionally arranged on the inner tube 200, so that the hollow composite tire has better shock absorption effect on the basis of better supporting strength, and the third chamber 210 can also improve the heat dissipation effect of the inner tube 200 and prolong the service life of the inner tube 200.

The above description is only exemplary of the present invention and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above exemplary embodiments according to the technical spirit of the present invention are within the technical scope of the present invention.
