Description

Internal and external integrated closed-loop tire

Technical Field

The invention belongs to the technical field of tires, and particularly relates to an internal and external integrated closed-loop tire.

Background

Tires, which are usually made of abrasion resistant rubber materials, are divided into solid tires and pneumatic tires, which often consist of inner tubes and outer tires. Great freight train of load or big truck use the relatively poor highway section in-process of road conditions is traveled to the tire of traditional interior outer tube design, because the relation of vehicle weight itself, and the structural strength difference of interior outer tube, the pressure that interior outer tube received is also completely different, the deformation degree that leads to producing is also different, and because the inboard of cover tire often with the structural design of open-loop, the joint is in wheel hub, under the deformation that produces the difference, deformation appears easily in interior outer tube, comparatively common appearance cover tire landing on wheel hub or because of deformation too seriously leads to phenomenons such as flat tire to take place. And because the inner tube produces extrusion deformation under the relatively poor condition of road conditions, lead to the easy tremor that takes place of big freight train that traveles, the comfort level is relatively poor, and extrusion deformation also lets inner tube of a tyre or cover tire life-span reduce by a wide margin simultaneously, brings huge potential safety hazard in the process of traveling.

Based on the defects, the existing tire structure is improved, the compression resistance of the tire is enhanced, the control performance and the safety of the vehicle are protected to achieve harmony and unity, and the problem is urgently solved at the present stage.

Disclosure of Invention

The invention aims to provide a tire which has strong pressure resistance, is not easy to burst, reduces the loss of a wheel hub and is more comfortable and safe to drive.

The purpose of the invention is realized as follows:

the utility model provides an inside and outside integral type closed loop tire, includes the tire body, this internal vacuole formation of tire, the tire body includes the closed loop type inner tube of a tyre and the outside closed loop type cover tire of being made by hard rubber by soft rubber outside to in proper order by interior, is provided with annular coil layer between the inner tube of a tyre and the cover tire, and the coil layer includes two-layer weaving layer at least, and every weaving layer is formed by the parallel and the same steel wire spiral winding of interval more than four strands, the tire body still includes the air cock, and the air cock runs through cover tire, coil layer and inner tube of a tyre are linked together with the vacuole formation, inner tube of a tyre, coil layer and cover tire.

The invention is further provided that the inner ring of the outer tyre is formed with a toe opening for clamping with the wheel rim.

The invention is further arranged that the upper and lower adjacent steel wires form an included angle of 10-90 degrees.

The invention is further configured such that the diameter of the steel wire is 0.3mm or more.

The invention is further arranged in such a way that the outer tire ring sequentially comprises a tire crown and a tire crown protective layer from outside to inside, and the surface of the tire crown is provided with tread patterns and tread grooves.

Compared with the prior art, the invention has the outstanding and beneficial technical effects that:

compared with the traditional tire, the tire adopts the inner tube and the outer tube which are integrally formed into a closed ring, the air tightness is greatly improved, and the coil layer is arranged between the inner tube and the outer tube, so that when the tire is locally stressed or in a large pressed state, the inner tube cannot deform to a large extent by virtue of the coil layer, the tire is not easy to slip off from the hub due to the reduction of the deformation, the service life of the tire is ensured, and the driving safety is ensured.

Detailed Description

The invention will be further described in the following with reference to specific embodiments in conjunction with the accompanying drawings, see fig. 1 and 2:

the utility model provides an inside and outside integral type closed loop tire, includes tire body 1, forms annular cavity 10 in the tire body 1, tire body 1 includes closed loop type inner tube 2 and the outside closed loop type cover tire 3 of being made by hard rubber that is made by soft rubber by interior outside to in proper order, is provided with annular coil layer 4 between inner tube 2 and the cover tire 3, and coil layer 4 includes at least two-layer weaving layer 40, and every weaving layer 40 is formed by parallel and the same steel wire 41 spiral winding of interval more than four strands, tire body 1 still includes air cock 5, and air cock 5 runs through cover tire 3, coil layer 4 and inner tube 2 are linked together with annular cavity 10, inner tube 2, coil layer 4 and cover tire 3 make as an organic whole.

The inner tube 2, the coil layer 4 and the outer tube 3 are integrally formed to discharge materials, the outer surface of the inner tube 2 abuts against the inner surface of the coil layer 4, and the inner surface of the outer tube 3 abuts against the outer surface of the coil layer 4.

Preferably, the inner ring of the outer tyre 3 is formed with a toe opening 30 for snap-fitting with a rim. The toe openings 30 are easily clamped in the wheel hub, and normal running of the tire is guaranteed.

Preferably, the steel wires 41 adjacent to each other at the upper and lower sides form an included angle of 10 ° to 90 °.

Preferably, the diameter of the steel wire 41 is 0.3mm or more.

Preferably, the outer ring of the outer tire 3 sequentially comprises a tire crown 31 and a tire crown protective layer 32 from outside to inside, and the surface of the tire crown 31 is provided with tread patterns and tread grooves.
