Embodiment 1

[0056] The high elastic hollow molded rubber tire of the present embodiment, as figure 1 , 2 As shown, it includes a tire body 6, the interior of the tire body 6 is a hollow-molded sealed cavity, and the sealed cavity is evenly separated into a plurality of tire sub-cavities 7 by a partition 9, without additional inflation, when a certain When the cavity is pierced, it does not affect the use of the tire; the inner ring of the tire body 6 is a tire clip 8 that fits the wheel hub, and the shape of the tire clip 8 fits the shape of the wheel hub, and is in a continuous concave-convex step shape. In order to stick to the wheel hub stably.

Embodiment 2

[0058] The high elastic hollow molded rubber tire of the present embodiment, as figure 1 , 2 As shown, the basic structure is the same as in Embodiment 1, and the improvement is that: the inner side of the tire sub-cavity 7 close to the hub is also covered with a tire inner layer 10, and the tire sub-cavity 7 is isolated from the outside world for a second time; the tire body The outer layer of 6 is provided with a steel wire braided layer and a nylon wire braided layer to meet the requirements of wear resistance and high strength; the tire card edge 8 is covered with a high-strength thick steel wire layer to ensure the fit between the tire and the wheel hub. The separator 9 and the tire body 6 are an integrated structure of the same material that is released from the same mold, and can be integrally injection molded; the separator 9 can be designed to be thin enough, smaller than the tire thickness, and enhance its elasticity; the material of the tire inner layer 10 It is a ...

Embodiment 3

[0060] The basic structure of the high-elastic hollow-molded rubber tire of this embodiment is the same as that of Embodiment 1, and the improvement is that: the outer layer of the tire body 6 is provided with a steel wire braided layer and a nylon wire braided layer to meet the requirements of wear resistance and high strength; the tire The card edge 8 is covered with a high-strength thick steel wire layer to ensure the fit between the tire and the wheel hub. The partition 9 and the tire body 6 are an integrated structure of the same material that is released from the same mold, and can be integrally injection molded; the partition 9 can be designed to be thin enough, less than the tire thickness, to enhance its elasticity.

[0061] The high-elastic hollow-molded rubber tire of this embodiment is produced by one-step injection, hollowing, and vulcanization processes of a one-time molding production system, and the injection, hollowing, and vulcanization of the high-elastic hol...

Abstract

The invention discloses a highly-elastic hollow molded rubber tire and a making process thereof and belongs to the technical field of a rubber tire product. The highly-elastic hollow molded rubber tire comprises a tire body; the interior of the tire body is a hollow molded sealing cavity; the hollow molded sealing cavity is uniformly separated into a plurality of tire sub-cavities by separation plates, so that no additional inflation is required; when a certain cavity is penetrated, the use of the tire is not affected; an inner ring of the tire body is a tire clamping edge matched with a wheelhub; the shape of the tire clamping edge is matched with the shape of the wheel hub and presents a continuous concave and convex step shape to be convenient for stable and tight fit with the wheel hub. The highly-elastic hollow molded rubber tire is prepared by one-step injection, and hollowing and vulcanization processes in a one-time molding production system; the injection, the hollowing and the vulcanization of the highly-elastic hollow molded rubber tire are completed in a mold, so that the circulation of a product in all the processes is avoided, and the production cost is reduced. Theproblems of low production efficiency of a manual de-molding core of the tubeless tire and high labor intensity and great labor intensity of workers are solved.

Description

technical field [0001] The invention belongs to the technical field of rubber tire products, and in particular relates to a high-elastic hollow-molded rubber tire and a manufacturing process thereof. Background technique [0002] Tires are one of the important components of a car. Its main function is to support the quality of the car, bear the load of the car, transmit traction and braking torque, and ensure the adhesion between the wheel and the road; reduce and absorb the vibration and impact of the car when it is running, and prevent the car from zero damage. The components are subject to severe vibration and early damage, adapt to the high-speed performance of the car and reduce the noise during driving, ensuring the driving safety, handling stability, comfort and energy-saving economy of the car. [0003] According to the requirements, the rubber tire must not only ensure its strength and wear resistance, but also ensure its elasticity. In order to ensure the two indic...
