Detailed Description
The present invention will be specifically described below by way of exemplary embodiments. It is to be understood that elements, structures, and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.
In the description of the present invention, it should be noted that the terms "inner", "outer", "upper", "lower", "front", "rear", and the like indicate orientations or positional relationships based on the positional relationships shown in fig. 1, and the terms "axial", "radial", "circumferential", and the like are based on the positional relationships shown in fig. 1, only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the apparatus or element in question must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, an inner support body for a tire comprises an inner support member 1, an outer support member 2, a pressure-bearing member 3 arranged between the inner support member 1 and the outer support member 2, and a limiting member 4 convexly arranged on the axial side surface of the pressure-bearing member 3, wherein the limiting member 4 and the inner support member 1 are arranged at intervals in the radial direction of the pressure-bearing member 3.
Referring to fig. 1-6, the inner support member 1, the pressure-bearing member 3, and the outer support member 2 are sequentially connected, and are preferably integrally formed, and the cross section of the tire inner support body in the radial direction is in an "h" shape, so as to effectively increase the pressure-bearing capacity of the tire inner support body, and the inner support member 1, the outer support member 2, and the pressure-bearing member 3 forming the "h" shape are preferably made of an environment-friendly material with high strength, low density, high elasticity, flex resistance, oxidation resistance, and low internal heat, such as thermoplastic or injection molding engineering plastics, i.e. modified polyurethane modified nylon. The circular through holes 31 penetrating through the pressure bearing piece 3 are arranged on the pressure bearing piece 3 along the axial direction of the pressure bearing piece 3, the circular through holes 31 are uniformly arranged in one or more layers along the circumferential direction of the pressure bearing piece 3, the circular through holes 31 are die drawing round holes, the die drawing angle is preferably 0-2 degrees, the design does not influence the normal running of the tire, can bear the impact force when the tire is burst, improves the supporting performance of the tire, is beneficial to the uniform and discrete transmission of the grounding pressure, and avoids the radial runout of the tire in the running process caused by the concentrated passing of the stress.
Referring to fig. 3-6, the limiting member 4 is protruded on the axial side surface of the pressure-bearing member 3, and is spaced from the inner support member 1, so as to leave a space, so that the toe can be inserted when the tire is mounted, and the toe can be blocked from moving inside the tire in the north-latitude direction of the tire bead, and the ring detachment can be prevented. The limiting piece 4 comprises a plurality of protruding portions 41 and a first end face 42 close to the inner supporting piece 1, if the number of the protruding portions 41 is one or more, the height of the protruding portions 41 is unchanged or is continuously increased along the direction far away from the inner supporting piece 1, and therefore the tyre can be prevented from being knocked off when the tyre is burst. The first end surface 42 is spaced from the inner support 1 by H, preferably 5-15mm, which is convenient for installation and prevents loopers.
The limiting piece 4 can be in various shapes, and can be in a polygonal shape such as a triangle, a trapezoid, a rectangle and the like, or in a curved shape such as an arc.
