DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] Existing aerial rail train bogies use solid tires, which are steel wheel rubber-covered structures. This solid tire structure has problems such as lack of buffering, high noise, and high repair and replacement costs when in use.

[0037] In view of this, the utility model provides a composite tire for an aerial rail train, comprising a wheel hub 100, a solid tire 200 and a pneumatic tire 300; the solid tire 200 is sleeved on the wheel hub 100, and the pneumatic tire 300 is sleeved on the solid tire 200 and clamped with the solid tire 200.

[0038] The composite tire for aerial rail train provided by the utility model replaces the cast solid tire 200 with a combination of a solid tire 200 and a pneumatic tire 300, and replaces the hard contact between the cast solid tire 200 and the running board with the elastic contact of the pneumatic tire 300, thereby providing a buffer for the operation of the aerial rail train, reducing the noise during operation and improving the riding comfort. The clamping connection between the pneumatic tire 300 and the solid tire 200 ensures the detachability of the two, reducing the difficulty of maintenance and replacement and the corresponding cost.

[0039] In particular, when the pneumatic tire 300 leaks during the operation of the train, the pneumatic tire 300 can be used as a consumable part and squeezed with the running board, thereby protecting the solid tire 200 and avoiding the loss of the solid tire 200. Only the pneumatic tire 300 needs to be replaced, thereby reducing the maintenance cost; and the solid tire 200 plays a supporting and buffering role, ensuring the normal operation of the train and avoiding damage to the wheel hub 100 after the pneumatic tire 300 used alone leaks.

[0040] The following combination Figure 1-Figure 7 The structure and shape of the composite tire for the aerial rail train provided in this embodiment are described in detail:

[0041] In an optional solution of this embodiment, a first annular groove 210 is provided on the solid tire 200, and a first annular protrusion 310 is provided on the pneumatic tire 300. Figure 6 , Figure 7 The first annular protrusion 310 is snap-fitted to the first annular groove 210. Figure 2 As shown, the solid tire 200 and the pneumatic tire 300 are detachably connected and the connection is reliable, axial movement is avoided, and the difficulty of maintenance and replacement is reduced. During maintenance, only the pneumatic tire 300 needs to be replaced, thus avoiding tire loss.

[0042] In an optional solution of this embodiment, a second annular groove 110 is provided on the wheel hub 100, and a second annular protrusion 220 is provided on the solid tire 200. The second annular protrusion 220 is clamped in the second annular groove 110. The clamping method prevents axial movement between the solid tire 200 and the wheel hub 100, thereby ensuring stability and safety of train operation. In this embodiment, the solid tire 200 is made of rubber and can be integrally connected to the wheel hub 100 by casting, or can be clamped for easy maintenance.

[0043] In this embodiment, a first air nozzle 120 is disposed on the wheel hub 100 . The first air nozzle 120 is inserted into the solid tire 200 and communicated with the inner cavity of the pneumatic tire 300 .

[0044] In this embodiment, the solid tire 200 is integrally connected to the wheel hub 100 by casting. To facilitate the installation of the pneumatic tire 300, the first air nozzle 120 does not protrude from the outer circumferential surface of the solid tire 200. The pneumatic tire 300 is provided with a first connecting tube 320. One end of the first connecting tube 320 is connected to the inner cavity of the pneumatic tire 300, and the other end is inserted into the first air nozzle 120 and connected to the first air nozzle 120, thereby realizing the connection between the pneumatic tire 300 and the air nozzle and ensuring the airtightness of the pneumatic tire 300. Figure 2 shown.

[0045] When the solid tire 200 is connected to the wheel hub 100 by means of a snap connection, the first air nozzle 120 does not protrude from the outer circumferential surface of the wheel hub 100, and a corresponding auxiliary connecting tube is provided on the platform, and a first connecting tube 320 is provided on the pneumatic tire 300. At this time, one end of the first connecting tube 320 is connected to the inner cavity of the pneumatic tire 300, and the other end is inserted into the auxiliary connecting tube, and the auxiliary connecting tube is inserted into the first air nozzle 120, so as to facilitate the installation of the solid tire 200 and the pneumatic tire 300.

[0046] Based on the composite tire for aerial rail train provided in this embodiment, a driving system for aerial rail train is proposed, including a bogie and a track beam, wherein the bogie includes the composite tire for aerial rail train, hereinafter referred to as the composite tire. The composite tire rolls along the running board of the track beam.

[0047] In this embodiment, the pneumatic tire 300 rolls along the running board of the track beam. In order to increase friction to provide sufficient driving force and braking force and prevent the train from slipping and sliding during operation, especially during climbing, the outer surface of the pneumatic tire 300 is provided with a protruding structure, and the surface of the running board in contact with the pneumatic tire 300 is provided with a groove structure. When the pneumatic tire 300 rolls on the running board, due to the gravity of the train, the pneumatic tire 300 undergoes a certain deformation, and the protruding structure will engage with the groove structure to increase the effective contact area between the pneumatic tire 300 and the running board, thereby increasing the friction force, especially the engagement of the protruding structure with the groove structure can provide a barrier for the rolling of the pneumatic tire 300 to limit the position, so that the pneumatic tire 300 obtains a more stable thrust and effectively prevents slipping and sliding. Specifically, the protruding structure and the groove structure can be set to a tooth shape, and the tooth-shaped structures can bite each other. That is, the tooth shape of the protruding structure extends along the axial direction of the pneumatic tire 300, and the protruding structure is evenly distributed along the circumference of the pneumatic tire 300. In addition, the groove structure can be formed by sandblasting, hammering, milling, etc. on the surface of the running board; the pneumatic tire 300 is set as a rubber tire, and a convex structure can be formed on the surface by vulcanization. The convex structure with appropriate density and size can ensure the smooth operation of the pneumatic tire 300 without bumps. The convex structure and the groove structure do not need to have the same shape, and the two can be engaged through the deformation of the pneumatic tire 300. It should be noted that the groove structure can be set only in the climbing section.

[0048] In this embodiment, multiple composite tires are interconnected. When one composite tire leaks air, the other composite tires are depressurized, thereby ensuring that the states of the composite tires are consistent and the bogie runs smoothly. When the composite tires rotate, the pneumatic tire 300 is worn, and the solid tire 200 is used to provide a buffer, thereby avoiding the situation where one composite tire is over-pressured and causes aggravated damage.

[0049] In this embodiment, the bogie further includes a frame body 10, a hollow shaft 20 and a rotary joint 30. Figure 8 , Fig. 9 The two composite tires are sleeved on the hollow shaft 20 and communicated with the inner cavity of the hollow shaft 20.

[0050] In this embodiment, two composite tires and a hollow shaft 20 form a wheel set. Fig. 9 As shown, the composite tire is mounted on the hollow shaft 20, and the hollow shaft 20 rotates around its own axis to drive the composite tire to rotate. The wheel hub 100 is also provided with a second air nozzle 130 connected to the inner cavity of the composite tire. Figure 4As shown, the first air nozzle 120 is used to inflate the composite tire, and the second air nozzle 130 is used to connect the composite tires for the aerial rail train. Specifically, the second air nozzle 130 is inserted into the solid tire 200 and communicated with the inner cavity of the pneumatic tire 300; the second air nozzle 130 has the same structure as the first air nozzle 120, and accordingly, its installation method is also the same as the first air nozzle 120. That is, the pneumatic tire 300 is provided with a second connecting tube 330. When the solid tire 200 is connected to the wheel hub 100 by casting, one end of the second connecting tube 330 is connected with the inner cavity of the pneumatic tire 300, and the other end is inserted into the second air nozzle 130 and communicated with the second air nozzle 130.

[0051] In this embodiment, two connecting holes communicating with the inner cavity are provided on the side wall of the hollow shaft 20. The two connecting holes are connected to the two second air nozzles 130 through air pipes, thereby connecting the composite tire and the inner cavity of the hollow shaft 20 to ensure the air pressure balance between the two.

[0052] In this embodiment, the bogie includes two wheel sets, that is, a total of four composite tires are provided. To achieve the connection of the four tires, the wheel set also includes a rotary joint 30, such as Fig. 9 Specifically, the hollow shaft 20 is provided with a blind hole extending along its own axis as an inner cavity, and the rotary joint 30 is installed in the blind hole to close the inner cavity of the hollow shaft 20 and achieve communication with the inner cavity of the hollow shaft 20, so as to ensure that no pipe winding occurs during operation, and the air pipe connects the rotary joints 30 of the two wheel sets to achieve communication of the four composite tires.

[0053] In order to ensure the installation of the rotary joint 30 , a clamping plate 101 is provided on the frame 10 , and the rotary joint 30 is clamped in a clamping groove of the clamping plate 101 , thereby ensuring the normal operation of the rotary joint 30 and preventing the air pipe from being wound.

[0054] The driving system for the aerial rail train provided in this embodiment ensures that the states of the pneumatic tires 300 are consistent by connecting the pneumatic tires 300, thereby making the train run smoothly. The raised structure of the pneumatic tire 300 improves the anti-skid performance while ensuring the wear resistance, especially by cooperating with the groove structure on the running board, further improving the anti-skid ability and ensuring driving safety and comfort.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
