Description

Technical Field

[0001] The utility model relates to an integrated wheel hub for an airless tire, belonging to the field of airless tires. Background Art

[0002] Airless tires are usually installed on metal wheel hubs, which can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle; most of the existing airless tires are installed on metal wheel hubs through a hoop structure, and no support structure is provided on the outer side of the airless tire, so the airless tire will twist and deform during use.

[0003] Currently, the common measure to prevent the airless tire from twisting and deforming is to install clamping pieces on both sides of the airless tire. In view of this, a patent document with the application number 202323575796.7 discloses an airless tire with clamping pieces. The clamping pieces on both sides of the above-mentioned existing airless tire are arranged in a split structure with the wheel hub, that is, the clamping pieces need to be installed on the wheel hub separately, and the installation process is relatively troublesome and cumbersome. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies existing in the prior art, and provide an integrated wheel hub for an airless tire with a reasonable structural design.

[0005] The technical solution adopted by the utility model to solve the above problems is: the integrated wheel hub for an airless tire is characterized in that: it includes a left wheel hub and a right wheel hub, the left wheel hub is connected to the right wheel hub, and both the left wheel hub and the right wheel hub include an inner ring, an outer ring, a wheel hub body and a clamping piece, and the inner ring, the outer ring and the clamping piece are all integrally arranged on the wheel hub body.

[0006] Further, a plurality of positioning columns for limiting the airless tire are arranged on the clamping piece, and the plurality of positioning columns are arranged in a circumferential array.

[0007] Further, a connecting seat for connecting the left wheel hub and the right wheel hub is arranged on the wheel hub body, and a connecting hole is arranged on the connecting seat.

[0008] Further, reinforcing ribs for improving the strength are arranged on the wheel hub body.

[0009] Further, positioning holes corresponding to the positioning columns are arranged on the airless tire.

[0010] Further, the left wheel hub and the right wheel hub are symmetrically arranged.

[0011] Further, the connecting holes of the wheel hub bodies in the left wheel hub and the right wheel hub are all penetrated by bolts.

[0012] Further, the inner ring, outer ring and clamping piece are all coaxially arranged with the hub body.

[0013] Further, the inner ring, outer ring and clamping piece are arranged in sequence from the center of the hub body to the outside.

[0014] Further, the reinforcing ribs include rectangular reinforcing ribs and annular reinforcing ribs. The inner ring and the outer ring are connected by the rectangular reinforcing ribs, and multiple connecting seats are connected by the annular reinforcing ribs.

[0015] Compared with the prior art, the present utility model has the following advantages: The left hub and the right hub of the one-piece hub for airless tires are respectively independently arranged. When in use, the airless tire is installed between the left hub and the right hub. The clamping piece is integrally arranged on the hub body. When the airless tire is clamped between the left hub and the right hub, the clamping piece can be clamped on both sides of the airless tire. Therefore, there is no need to independently install the clamping piece, which can improve the installation efficiency and make the installation more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The one-piece hub for an airless tire in this embodiment includes a left hub A and a right hub B. The left hub A is connected to the right hub B, and the left hub A and the right hub B are symmetrically arranged.

[0028] Both the left hub A and the right hub B in this embodiment include an inner ring 1, an outer ring 2, a hub body 3, and a clamping piece 4. A plurality of positioning posts 5 for limiting the airless tire C are provided on the clamping piece 4. The plurality of positioning posts 5 are arranged in a circumferential array, and positioning holes 9 corresponding to the positioning posts 5 are provided on the airless tire C.

[0029] The inner ring 1, the outer ring 2, and the clamping piece 4 in this embodiment are all integrally provided on the hub body 3. The inner ring 1, the outer ring 2, and the clamping piece 4 are all coaxially arranged with the hub body 3, and the inner ring 1, the outer ring 2, and the clamping piece 4 are arranged in sequence from the center of the hub body 3 outward.

[0030] A connecting seat 6 for connecting the left hub A and the right hub B and a reinforcing rib 8 for enhancing the strength are provided on the hub body 3 in this embodiment. A connecting hole 7 is provided on the connecting seat 6. Bolts pass through the connecting holes 7 of the hub body 3 in both the left hub A and the right hub B. The reinforcing rib 8 includes a rectangular reinforcing rib and an annular reinforcing rib. The inner ring 1 and the outer ring 2 are connected by the rectangular reinforcing rib, and the plurality of connecting seats 6 are connected by the annular reinforcing rib.

[0031] Specifically, the one-piece hub for an airless tire includes a left hub A and a right hub B. The inner ring 1, the outer ring 2, the clamping piece 4, the connecting seat 6, and the reinforcing rib 8 in both the left hub A and the right hub B are all integrally structured with the hub body 3 (i.e., the "one-piece" in this application). When in use, the airless tire C is installed between the left hub A and the right hub B, and then bolts are passed through the connecting holes 7, and thus the left hub A and the right hub B can be fixed.

[0032] A clamping piece 4 is arranged on the hub body 3, and the tire can be clamped between the two clamping pieces 4. A positioning post 5 is arranged on the clamping piece 4, and the positioning post 5 is inserted into the positioning hole 9 of the non-pneumatic tire C, so as to prevent the tire from displacing and sliding between the two clamping pieces.

[0033] By arranging the clamping piece 4 on the hub body 3, the two clamping pieces 4 clamp the non-pneumatic tire C. Therefore, the rubber material of the non-pneumatic tire C can be made softer, more elastic and more conforming to the contact surface of the hub. The middle part of the non-pneumatic tire C is designed as a concave structure. When the non-pneumatic tire C is installed on the left hub A and the right hub B, a hollow part D will exist between the concave structure of the non-pneumatic tire C and the integrated hub. This hollow part D can increase the hollow space to absorb the vibration amplitude.

[0034] In addition, it should be noted that for the specific embodiments described in this specification, the shapes and names of the components can be different. The above content described in this specification is only an example of the structure of the present invention.
