Embodiment Construction

[0028] Hereinafter, embodiments of the present invention will be described in detail.

[0029] Such as figure 1 and figure 2 As shown in , the non-pneumatic tire 1 according to the first invention includes a cylindrical tread ring 2 having a contact area S, a hub 3 and spokes 4, and the hub 3 is arranged on the diameter of the tread ring 2. On the inside and fixed to the axle J, and the spokes 4 connect the tread ring 2 with the hub 3 . This embodiment shows a case where a non-pneumatic tire is formed as a tire for a passenger vehicle.

[0030] The tread ring 2 is a portion corresponding to a tread portion of a pneumatic tire and includes a tread rubber portion 2A and a reinforcing cord layer 2B embedded in the tread rubber portion 2A.

[0031] For the tread rubber portion 2A, it is preferable to employ a rubber composition excellent in frictional force to ground contact and wear resistance. And in order to impart wet performance, on the contact area S forming the outer p...

Abstract

The present invention increases the bonding strength between a spoke and a tread ring and / or between a spoke and a hub to improve durability. An airless tire provided with a tread ring, a hub, and a spoke, wherein the spoke is integrally provided with: an outer annular part the outer peripheral surface of which is bonded to the inner peripheral surface of the tread ring via a first adhesion layer; an inner annular part the inner peripheral surface of which is bonded to the outer peripheral surface of the hub via a second adhesion layer, and a spoke part which couples the inner and outer annular parts. The inner peripheral surface of the tread ring and / or the outer peripheral surface of the hub is composed of a rough surface having a surface roughness (Ra) (arithmetic average roughness) of 3-1000 [mu]m or a surface roughness (Rz) (ten-point average roughness) of 30-5000 [mu]m.

Description

technical field [0001] The present invention relates to an airless tire having increased bonding strength between a spoke and a tread ring and / or between a spoke and a hub to improve durability, and a method for manufacturing the same. Background technique [0002] As traditional non-pneumatic tires, solid tires with a solid rubber structure are mainly used for industrial vehicles. However, tires with solid rubber construction are more massive and less shock-absorbing. Therefore, this tire is not suitable for passenger cars that value ride comfort. [0003] In order to improve the ride comfort of such non-pneumatic tires so that the tires can be applied to passenger cars, a structure (hereinafter may be referred to as a "spoke structure") (for example, See Patent Document 1). [0004] And Patent Document 1 proposes adhesive bonding between the tread ring and the spokes and between the spokes and the hub. In this case, sufficient bonding strength can be ensured by appropr...
