Problems solved by technology

[0004] However, since the above-mentioned composite solid tire is that the inner tire and the outer tire are fitted in a non-adhesive state, the following phenomenon sometimes occurs, that is, for example, when braking, both the inner tire and the outer tire are dislocated in the tire circumferential direction, and the braking force Insufficient transmission, and when rotating in a non-driving state, both the inner tube and the outer tire are misaligned in the axial direction of the tire, and the sidewall of the outer tire forms a gap
Therefore, these undesirable phenomena hinder above-mentioned solid tire from reaching practical use

Embodiment

[0052] As tires for heavy transport vehicles, manufactured with figure 1 The tire structure shown, the composite solid tire (Example 1) whose dimensions are shown in Table 1, and, having Figure 8 The tire structure shown, its dimensions are as shown in Table 1 Composite solid tire (Example 2). In addition, for comparison, the Figure 8 Composite solid tires with different tire structures and dimensions as shown in Table 1 (Comparative Examples 1 to 3).

[0053] In Table 1, the inner peripheral length of the tire case is expressed as a ratio (%) to the outer peripheral length of the inner tube. The developed width of the inner peripheral surface of the tire case is represented by a ratio (%) to the developed width of the outer peripheral surface of the inner tube. The radius of curvature of the inner peripheral surface of the tire case is expressed as a ratio (%) to the radius of curvature of the outer peripheral surface of the inner tube.

[0054] In addition, in Table 1,...

Abstract

A compound solid tire capable of preventing a core tire from being displaced from a cover tire and preventing the side part of the cover tire from opening, comprising the core tire formed of an annular elastic body and the annular cover tire having an inner peripheral surface fitted to the outer peripheral surface of the core tire, the cover tire further comprising a tread part and side parts, wherein the inner peripheral length of the cover tire at the inner peripheral surface center position is set to 92 to 99.5% of the outer peripheral length of the core tire at the outer peripheral surface center position.

Description

technical field [0001] The invention relates to a composite solid tire with a double-layer structure of the inner tire and the outer tire, more specifically, relates to a composite solid tire which can prevent the displacement of the inner tire and the outer tire and prevent the sidewall of the outer tire from opening. Background technique [0002] Solid tires are superior to pneumatic tires in terms of their high load capacity and lack of air leakage problems, especially in heavy-haul vehicles, because they are constructed of a solid, elastic material. [0003] Regarding the above-mentioned solid tire, the present inventors have proposed, as disclosed in Japanese Patent No. 3245619, that the solid tire is composed of an inner tube and a tire (crown), and the two are fitted together in a non-adhesive state. Such a composite solid tire has the advantages of being able to exhibit the soft elastic performance of a pneumatic tire without reducing the load carrying capacity, and ...
