A wheel and walking equipment with the wheel

Abstract

The invention discloses a wheel. A hub of the wheel is adaptive to a rotating shaft of running equipment; a plurality of elastic supporting pieces are uniformly distributed on the peripheral surface of the hub in the circumferential direction; bodies of the elastic supporting pieces extend outwards to form end part external circular arc sections; the external circular arc sections of the pluralityof elastic supporting pieces are arranged in sequence in a spaced manner in the circumferential direction and have concentric and isodiametric convex circular arc surfaces; the elastic supporting pieces have stress deformation areas and stress position changing areas and are configured in such a way that the stress deformation areas are positioned at the middle sections of the main bodies; the direction of deformation stress generated under an outside force in the moving process tends to be consistent with the tangential direction of the rotation of the hub so that an acting force for pushingthe hub to rotate is formed during releasing the deformation stress; and the external circular arc sections are the stress position changing areas and can generate displacements with the deformations. According to the scheme, as the traditional rigid structure is transformed into rigid and soft combined structure, and an outer tire is eliminated, good running performance can be obtained, and theinfluence of a severe use environment on the service life of the wheel can be effectively avoided. The invention further provides running equipment with the wheel.

Description

technical field

[0001] The invention relates to the technical field of mechanical wheels, in particular to a wheel and walking equipment with the wheel. Background technique

[0002] As we all know, traditional wheels focus on rolling continuity, which obtains rolling friction through an annular closed rigid rim. Most of the existing wheels are composed of a rim, a hub, spokes, and a tire covering the outer periphery of the rim, wherein the hub forms a rigid disc-shaped structure through the spokes and the rim, and absorbs the impact and vibration loads during the bearing process through the tire .

[0003] The cover tire of existing automatic car or motor vehicle mainly comprises two kinds of structural forms, and a kind of is an air-filled rubber tire, and another kind is solid rubber or silicon rubber cover tire. Due to the limitation of its material, when the temperature rises significantly during driving, it will directly affect the safety and life of use; in the case...

Examples

Embodiment 1

[0039] See figure 1 and figure 2 ,in, figure 1 It is a three-dimensional schematic diagram of the wheel described in this embodiment, figure 2 is the front view of the wheel.

[0040] The wheel mainly includes a hub 1 adapted to a rotating shaft (not shown in the figure) of the walking equipment and elastic supports 2 , and a plurality of elastic supports 2 are evenly distributed on the outer peripheral surface of the hub 1 in the circumferential direction. Here, the plurality of elastic supports 2 have both the functions of the spokes and the rim of the traditional wheel, and the outer tire is canceled based on its own ability to combine rigidity and flexibility.

[0041] As shown in the figure, the body of the elastic support 2 extends outward to form an outer arc segment 21 at the end, and the outer arc segments 21 of a plurality of elastic supports 1 are sequentially arranged at intervals in the circumferential direction, and two adjacent outer arc segments form Incons...

Embodiment 2

[0051] The difference between this solution and the first embodiment lies in the change of the hub structure and the addition of optional adapters 14, so that it can be applied to the temporary substitute function of another walking equipment. See Figure 5 , the figure shows a schematic diagram of the assembly relationship of another use state of the wheel described in this embodiment. In order to clearly show the difference and connection between this embodiment and Embodiment 1, the same functional components in the figure are shown with the same symbols.

[0052] Specifically, the inner ring part 11 is integrated with a plurality of inner elastic support parts 12, and can be detachably connected with the outer ring part 13, such as threaded connection or snap connection; that is, the inner ring part 11 and the inner elastic support parts The part 12 can be disassembled from the outer ring part 13, wherein, the optional adapter part 14 can also be detachably connected with ...

Embodiment 3

[0055] The difference between this solution and Embodiment 1 or Embodiment 2 is that the wheel is additionally provided with a rubber coating layer 3, the rubber coating layer 3 covers a plurality of elastic supports 2, and the overall outer contour is in the shape of a continuous disc, forming Overall coverage. See Figure 8 , this figure is a schematic diagram of the wheel described in this solution. In order to clearly show the differences and connections between this implementation and Embodiments 1 and 2, the same functional components in the figure are shown with the same symbols.

[0056] That is to say, the gaps (openings) are connected by flexible materials, and the appearance of the wheel is disc-shaped like a traditional wheel, that is, the combination of rigidity and flexibility of the disc structure is composed of an elastic skeleton and a high-elastic covering material. The circle is coherent, further improving its running stability. Here, the rubber coating la...
