DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0030] Please refer to Figure 1-Figure 7 As shown, an embodiment of the present application provides a running wheel for an aerial rail train, comprising a rim 1, a tire 2 and a support body 3, wherein:

[0031] The rim 1 comprises a rim body 11 and a side ring 12, wherein the side ring 12 is detachably connected to the rim body 11;

[0032] The tire 2 is mounted on the rim body 11 and is clamped between the side ring 12 and the rim body 11 in the axial direction;

[0033] The support body 3 is sleeved on the rim 1 and located in the rim 1. The support body 3 includes at least two arc-shaped rings 311. At least the arc-shaped rings 311 are detachably connected to each other.

[0034] The sky rail train running wheel provided in this embodiment is clamped between the side ring 12 and the rim body 11 in the axial direction of the tire 2. The side ring 12 and the rim body 11 are detachably connected, which facilitates the installation and removal of the tire 2 and the rim 1. The support body 3 includes at least two arc rings 31, at least the arc rings 31 are detachably connected to each other, and multiple arc parts can be assembled or disassembled in the tire 2, which facilitates the placement of the support body 3 in the tire 2 or removal from the tire 2, thereby greatly improving the efficiency of replacing the tire 2.

[0035] In some optional embodiments, the arcuate ring 31 has a first overlapping groove 311 and a second overlapping groove 312 on opposite sides thereof, respectively. The first overlapping groove 311 and the second overlapping groove 312 of two adjacent arcuate rings 31 overlap each other. The first overlapping groove 311 and the second overlapping groove 312 are respectively provided at both ends of the arcuate ring 31 and are located on opposite sides of the arcuate ring 31. When the first overlapping groove 311 of a current arcuate ring 31 overlaps the second overlapping groove 312 of an adjacent arcuate ring 31, the flatness of the two side surfaces of the support body 3 along the axial direction is ensured.

[0036] In some optional embodiments, three arcuate rings 31 are provided, and the three arcuate rings 31 are evenly spaced along the circumference. By evenly arranging the three arcuate rings 31 along the circumference, the arcuate rings 31 can be made more symmetrical, so that the axis of the support body 3 is as coaxial as possible with the axis of the rim 1, thereby avoiding affecting the balance of the vehicle and improving the stability of the device.

[0037] Of course, two arc rings 31 can be provided, each of which has an arc of 180 degrees; four or more arc rings 31 can also be provided, which can be arranged according to actual needs.

[0038] In some optional embodiments, a first clamping protrusion 111 is provided on an end face of the rim body 11 away from the side ring 12, and a second clamping protrusion 121 is provided on the back side of the connection surface between the side ring 12 and the rim body 11. The first clamping protrusion 111 and the second clamping protrusion 121 are used to clamp the upper and lower ends of the inner opening of the tire 2. The first clamping protrusion 111 and the second clamping protrusion 121 are used to clamp the upper and lower ends of the inner opening of the tire 2, thereby limiting the two ends of the tire 2, improving the tightness of the connection between the tire 2 and the rim 1, and facilitating the installation and removal of the tire 2, thereby improving the installation and removal efficiency.

[0039] In some optional embodiments, the connecting surface between the side ring 12 and the rim body 11 is provided with an abutment portion 122, which is configured to abut the support body 3. The abutment portion 122 is formed by extending the side ring 12 along the axial direction away from the second clamping protrusion 121. The abutment portion 122 abuts the support body 3, limiting the top of the support body 3. Simultaneously, the outer wall of the abutment portion 122 abuts the inner opening of the tire 2, and together with the second clamping protrusion 121, applies a clamping force to the tire 2. A certain gap can be maintained between the bottom of the clamping portion and the support body 3, allowing a certain amount of movement of the support body 3 to allow for a certain degree of installation error and improve applicability, but preventing significant movement that would affect the balance of the wheel.

[0040] In some optional embodiments, a limiting portion 112 is provided in the middle portion of the outer wall of the rim body 11. The outer diameter of the limiting portion 112 is larger than the inner diameter of the support body 3. The limiting portion 112 is used to abut the side of the support body 3 away from the abutting portion 122. By setting the outer diameter of the limiting portion 112 to be larger than the inner diameter of the support body 3 and the limiting portion 112 abutting the side of the support body 3 away from the abutting portion 122, the limiting portion 112 and the abutting portion 122 respectively limit the two sides of the support body 3, so that the support body 3 is positioned at a designated position on the rim 1, which facilitates the installation of the support body 3 while improving the reliability and stability of the device.

[0041] In some optional embodiments, the rim body 11 is provided with a threaded countersunk hole 113, and the side ring 12 is provided with a mounting hole 123. The rim 1 further includes a mounting bolt, which is configured to pass through the mounting hole 123 and connect with the threaded countersunk hole 113. By passing the mounting bolt through the mounting hole 123 and connecting with the threaded countersunk hole 113, a detachable connection between the side ring 12 and the rim body 11 is achieved, facilitating installation and removal of the side ring 12 from the rim body 11.

[0042] In some optional embodiments, the rim 1 further includes at least two positioning posts 4, which are used to connect with the threaded countersunk holes 113 and pass through the mounting holes 123 to position the side ring 12. When connecting the side ring 12 to the rim body 11, the two positioning posts 4 can be connected to the threaded countersunk holes 113, and the mounting holes 123 on the side ring 12 can be sleeved on the positioning posts 4 to achieve positioning of the side ring 12, thereby achieving alignment between the side ring 12 and the rim body 11, improving installation efficiency. After connecting the other threaded countersunk holes 113 and mounting holes 123 with mounting bolts, the positioning posts 4 are removed, and the threaded countersunk holes 113 and mounting holes 123 to which the positioning posts 4 are mounted are fastened with mounting bolts.

[0043] In some optional embodiments, the positioning post 4 includes a threaded section 41, an optical axis section 42, and an operating section 43. The threaded section 41 is configured to connect to the threaded counterbore 113, and the ends of the optical axis section 42 are respectively connected to the threaded section 41 and the operating section 43. The operating section 43 has a polygonal cross-section. The threaded section 41 connects to the threaded counterbore 113 to achieve a detachable connection between the positioning post 4 and the rim body 11. The optical axis section 42 is inserted into the mounting hole 123 to position the side ring 12, thereby achieving alignment between the side ring 12 and the rim body 11. The operating section 43 has a square cross-section to facilitate rotation of the positioning post 4 to achieve a threaded connection.

[0044] In some optional embodiments, the support body 3 has an I-shaped cross section. The arcuate rings 31 may be provided with connecting holes 313 on the first overlapping groove 311 and the second overlapping groove 312. Connecting bolts pass through the connecting holes 313 and are connected to connecting nuts to achieve connection between adjacent arcuate rings 31. Because the support body 3 has an I-shaped cross section, the connecting holes 313 may be provided in the thin middle wall of the I-shape. This allows the connecting bolts and nuts to not protrude from the two side surfaces in the axial direction of the support body 3, freeing up more installation space for the connection between the connecting nuts and the connecting bolts, thereby improving reliability and stability.

[0045] The working principle of the skytrain running wheel proposed in the present invention is as follows: a plurality of arc-shaped rings 31 are placed in the tire 2, the first overlapping groove 311 and the second overlapping groove 312 of two adjacent arc-shaped rings 31 are overlapped with each other, and the support body 3 is spliced ​​by passing the connecting bolt through the connecting hole 313 and connected to the connecting nut; the support body 3 is pressed down until it abuts the limit portion 112; the side ring 12 is connected to the rim body 11, thereby realizing the assembly of the wheel; when disassembling, the above steps are reversed. The skytrain running wheel in this embodiment is detachably connected to the rim body 11 by the side ring 12, which facilitates the installation and disassembly of the tire 2 and the rim 1. It can be assembled or disassembled in the tire 2 through a plurality of arc-shaped parts, which facilitates the placement of the support body 3 in the tire 2 or removal from the tire 2, greatly improving the efficiency of tire 2 replacement.
