no. 1 approach

[0042] like Figure 1 to Figure 8 As shown, the present invention proposes a shock-absorbing silent wheel (hereinafter sometimes referred to as tire), the tire includes a rim 1 and a hub 2, the rim 1 and the hub 2 are annular, the rim 1 and the hub 2 are fixed together, and the rim 1 is located on the radially outer side of the hub 2, for example, the rim 1 and the hub 2 can be connected together by clamping, bonding, two-color injection molding or secondary injection molding.

[0043] The present invention also proposes a movable device. One or more shock-absorbing and silent wheels are installed on the bottom of the movable device, and the shock-absorbing and silent wheels are installed on the movable device in a manner that the hub 2 is mounted on a shaft. The shock-absorbing silent wheels can make the mobile equipment generate less vibration and noise when moving on the ground. The weight of the movable equipment is relatively light. For example, the movable equipment can...

no. 2 approach

[0072] The overall structure of the shock-absorbing and silent wheel of the second embodiment is similar to that of the first embodiment. In the second embodiment, the same or similar structures as the first embodiment use the same reference numerals, and no Detailed Description.

[0073] like Figure 9 As shown, the shock-absorbing and silent wheel includes a rim 1 , a hub 2 and a tread 3 , and the tread 3 is connected to the radially outer side of the outer layer 11 . Tread 3 is the part in contact with the ground of the shock-absorbing silent wheel as the outermost layer of the shock-absorbing silent wheel. The tread 3 may be formed by injection molding, pouring or molding processes. The tread 3 is made of elastic material, which can be cast polyurethane, thermoplastic elastomer or vulcanized rubber. The tread 3 can be made of an elastic material whose stress (elastic modulus) at 10% elongation is less than or equal to 60 Mpa, for example, a material with an elastic modu...

no. 3 approach

[0097] The overall structure of the vibration-absorbing and silent wheel of the third embodiment is similar to that of the first embodiment. In the third embodiment, the same or similar structures as those of the first embodiment use the same reference numerals, and are not carried out. Detailed Description.

[0098] like Figure 13 As shown, the outer layer 11 is provided with a reinforcing piece 14, the reinforcing piece 14 is annular, and the radial dimension of the reinforcing piece 14 can be 0.5 mm to 5 mm. The reinforcing member 14 can be made of stainless steel, and the stress of the banner 12 can be reduced through the traction effect on the banner 12, thereby increasing the service life of the tire.

[0099] The material forming the reinforcement 14 is made of a material with an elastic modulus of 500 Mpa or higher, preferably a material with an elastic modulus of 2000 Mpa or higher, such as metal (including alloys) or plastic. If the reinforcement 14 is made of met...

Abstract

The invention provides a damping mute wheel and movable equipment. The damping mute wheel comprises a hub which is annular; the wheel rim is fixedly connected to the radial outer side of the wheel hub; the rim comprises an outer layer, spokes and a transition layer. The spokes are located on the radial inner side of the outer layer, the transition layer is located on the radial inner side of the spokes, the transition layer is connected with the hub, the multiple spokes are evenly arranged in the circumferential direction of the damping mute wheel at intervals, the rim is hollowed out due to the intervals between the spokes, and the spokes are integrally bent to be of a C-shaped structure; and the reinforcing part is annular, the reinforcing part is connected to the outer layer, and the elasticity modulus of the material forming the reinforcing part is larger than that of the material forming the rim. By the adoption of the technical scheme, vibration and noise of the tire can be reduced, and the movable equipment can be kept quiet when moving.

Description

technical field [0001] The invention belongs to the field of tires, in particular to a shock-absorbing silent wheel and movable equipment. Background technique [0002] Moving equipment such as luggage over rough or uneven surfaces can generate vibration and noise. In order to avoid these vibrations and noises, solid rubber tires, foam tires, pneumatic tires, etc. are often used as tires to carry movable equipment in the prior art, which achieves a certain effect of vibration and noise reduction. But moving on uneven roads, there is still a strong noise. In order to further reduce vibration and noise, the prior art also adopts the following technical solutions: [0003] (1) A damping spring is arranged between the tire and the movable device, and the spring has a certain damping effect. Although the way of spring damping can slow down vibration and reduce noise to a certain extent, but the damping of spring has directionality and can only reduce the vibration impact in on...
