Problems solved by technology

However, due to the two-stage mechanical assembly of this kind of air-free tire, the reliability of the combination between the outer tire, the inner tube and the wheel frame is not good, and the outer tire or the inner tube is easy to be separated from the tire, which is prone to danger in use, and the use of life is not long

Embodiment Construction

[0016] Detailed description of the preferred embodiment:

[0017] See figure 2 versus image 3 , Which are respectively a front view and a cross-sectional view of the pneumatic tire 100 according to the present invention. Such as image 3 As shown, the pneumatic tire 100 according to the present invention includes: a tire inner frame 110; a carcass film 130; and an inner tube layer 120. Such as figure 2 As shown, the side surface of the carcass film 130 has at least one pouring hole 131 for pouring the foam material forming the inner carcass layer 120. The number of injection holes 131 can be increased or decreased depending on the material of the inner tube layer 120. More than one perfusion hole 131 is evenly distributed on the side surface of the tyre membrane 130.

[0018] The tire inner frame 110 is made of a material with higher hardness, and the material of the tire inner frame 110 may be metal or plastic with higher hardness. The outer side of the carcass film 130 has th...

Abstract

The production process of non-inflation tyre includes: preparing one inner tyre frame; setting the inner frame inside mold and rotating injection or jetting formation to produce outer rubber layer with at least one perfusion hole; perfusing inner tyre material via the perfusion hole; foaming the inner tyre material for the close combination among the inner tyre frame, the inner tyre material and the outer rubber layer. The non-inflation tyre includes one inner tyre frame; one outer rubber layer with at least one perfusion hole and formed through rotating injection or jetting formation; and one inner tyre layer of foamed material combined closely.

Description

(1) Technical field [0001] The invention relates to a method for manufacturing a non-pneumatic tire and a non-pneumatic tire, and more particularly to a non-pneumatic tire with a tire inner frame, an inner tube layer and a tyre film for baby carriages or children's toys, and a manufacturing method thereof. (2) Background technology [0002] With the progress of the times and the improvement of the quality of life, the wheels of strollers or children's toys have many different designs. Traditional pneumatic tires have an outer tire and an inner tube. The outer tire is made of rubber and the inner tube is hollow. The inner tube needs to be inflated before use. This kind of pneumatic tire has the disadvantage of being easy to puncture, even if it does not puncture. There is a need to inflate frequently. [0003] In view of the shortcomings of pneumatic tires, non-pneumatic tires were developed. Early inflatable tires were all made of foamed materials (such as EVA plus foaming agent)...
