Description

Technical Field

[0001] This utility model relates to the field of automobile tire technology, specifically to an outer support body, a tire inner support structure including the outer support body, and a tire. Background Technology

[0002] Existing car tires typically use elastic supports to absorb shocks or provide some support to the vehicle. Currently, car tires usually use air springs as the elastic support for locking and control. However, air springs are expensive to manufacture and have a relatively short lifespan. Furthermore, during driving, if the vehicle tilts excessively, the elastic support in the air spring may experience uneven stress, resulting in misalignment. Bumps and vibrations from the vehicle can also affect the normal operation of the air spring. In addition, after prolonged use, air springs may experience wear or aging, leading to performance degradation or positional instability. Utility Model Content

[0038] Example 1

[0039] Example 1 provides an outer support 1, which has a ring structure and its inner side is connected to the outer side of an elastic support 2 through a connector. The inner side of the outer support 1 is provided with an inner support portion 111 that protrudes toward the elastic support 2. The inner support portion 111 slightly presses the outer side of the elastic support 2 to make the elastic support 2 partially concave.

[0040] The outer support 1 provided in this embodiment has a ring-shaped structure and is connected to the outer side of the elastic support 2. The inner side of the outer support 1 is provided with an inwardly recessed inner support part 111 to slightly press the outer side of the elastic support 2, causing the elastic support 2 to partially indent. By improving the structure of the outer support 1 itself, the outer support 1 and the elastic support 2 can be well matched, preventing the elastic support 2 from being excessively tilted and running out. Moreover, this structure is low in cost and highly practical.

[0041] In this embodiment, the outer side of the outer support body 1 is provided with an outwardly protruding outer support portion 112.

[0042] In this embodiment, the outer support 1 includes one or more outer pressure rings 11. The outer pressure rings 11 are annular structures. The one or more outer pressure rings 11 have a certain pressure bearing capacity and elastic recovery force. The inner side of the outer pressure ring 11 is provided with an inwardly recessed inner support portion 111 and the outer side is provided with an outwardly protruding outer support portion 112.

[0043] When the outer support 1 includes an outer bearing ring 11, the inner support part 111 presses against the outer side of the elastic support.

[0044] When the outer support 1 includes multiple outer pressure rings 11, the multiple outer pressure rings 11 are stacked in sequence. The inner support portion 111 of the outer pressure ring 11 closest to the elastic support 2 presses against the outer side of the elastic support 2. In two adjacent outer pressure rings 11, the inner support portion 111 of one outer pressure ring 11 and the outer support portion 111 of the other outer pressure ring 11 are positioned correspondingly.

[0045] In this embodiment, when the outer support 1 includes multiple outer pressure rings 11, the pressure of the inner support 111 on the elastic support 2 is ensured to be low by the superposition of multiple outer pressure rings 11, thus preventing the elastic support 2 from exploding and not reducing the pressure bearing capacity of the elastic support 2. On the contrary, it can increase the pressure bearing capacity of the elastic support 2 to a certain extent.

[0046] In this embodiment, the connector is made of a flexible and elastic material to give it high strength and high toughness. The connector is evenly laid between the outer support 1 and the elastic support 2. This even laying ensures maximum contact area between the connector and the outer support 1 and elastic support 2, thereby increasing bonding strength. The even laying also ensures a stable connection between the outer support 1 and elastic support 2, improving the stability and safety of the overall structure.

[0047] In this embodiment, when the outer support 1 includes an outer pressure ring 11, the inner side of the outer pressure ring 11 is connected to the outer side of the elastic support 2 through a connector.

[0048] In this embodiment, when the outer support 1 includes multiple outer pressure rings 11, the inner side of the innermost outer pressure ring 11 is connected to the outer side of the elastic support 2 through a connector, and the remaining outer pressure rings 11 are stacked in sequence from the inside to the outside relative to the innermost outer pressure ring 11, and adjacent two outer pressure rings 11 are connected through a connector.

[0049] By configuring the outer support 1 as a structure comprising multiple outer bearing rings 11, with adjacent outer bearing rings 11 and connecting bodies forming a sandwich shell structure, this structure is characterized by its light weight, high strength, and high rigidity, and achieves good vibration resistance, heat insulation, sound insulation, and other necessary properties. Furthermore, by avoiding large-area riveting, stress concentration is reduced, resulting in a significant improvement in fatigue strength. Due to these advantages, sandwich shell structures are increasingly widely used in various military and civilian sectors. Mechanically, the two outer bearing rings 11 serve as the main load-bearing layers, while the connecting bodies form a sandwich structure that expands and firmly bonds the two outer bearing rings 11 together, bearing shear stress. This is similar to the concept of an I-beam, where the two outer bearing rings 11 act as flanges, and the connecting bodies form a sandwich structure that acts as a web.

[0050] In this embodiment, the cross-sections of the inner support 111 and the outer support 112 are umbrella-shaped, so as to further apply gradually increasing and smooth pressure to the elastic support 2 from both sides of the inner pressure ring to the middle of the inner pressure ring, to prevent the elastic support 2 from exploding, without reducing the pressure bearing capacity of the elastic support 2, but rather to a certain extent increasing the pressure bearing capacity of the elastic support 2.

[0051] In this embodiment, the radii of the inner support portion 111 and the outer support portion 112 are much smaller than the radius of the outer pressure ring 11, ensuring that the pressure of the inner support portion 111 on the elastic support body 2 is a small pressure.

[0052] In this embodiment, the number of inner support 111 and / or outer support 112 is one or more, and the inner support 111 and outer support 112 are integrally formed with the outer support body 1 or fixedly connected by welding.

[0053] In this embodiment, when there is one inner support 111 and / or one outer support 112, the inner support 111 and / or the outer support 112 are annular, and the inner support 111 is located in the middle of the inner side of the outer support body 1, and the outer support 112 is located in the middle of the outer side of the outer support body 1.

[0054] In this embodiment, when there are multiple inner support portions 111 and / or outer support portions 112, the inner support portions 111 and / or outer support portions 112 are ring-shaped or hill-shaped, and multiple inner support portions 111 are symmetrically arranged on the inner side of the outer support body 1, and multiple outer support portions 112 are symmetrically arranged on the outer side of the outer support body 1.
