Description

Technical Field

[0001] This utility model relates to the field of wheel hub technology, and in particular to a split-type airless wheel hub. Background Technology

[0002] Conventional wheel rims typically use a one-piece structure, mainly because a one-piece structure can greatly increase the structural strength of the wheel rim. However, this type of rim has a problem: it cannot install pneumatic tires. To facilitate the installation of pneumatic tires, the rim structure needs to be modified. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a split-type airless wheel hub, which has the characteristics of small overall weight, convenient installation of airless tires, low production cost, convenient connection with axle, and high structural strength.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a split-type airless wheel hub is provided, including a hub base, a hub cover plate and a tire fixing groove. The hub cover plate is installed on the upper surface of the hub base. A tire fixing groove is provided between the outer ring of the hub base and the hub cover plate. The hub base includes an outer hub, a middle base and a thin sheet support frame. The middle base is provided in the middle of the outer hub. At least three thin sheet support frames are evenly arranged between the middle base and the inner ring of the outer hub. One end of the thin sheet support frame wraps around the middle base, and the other end is diffused and connects with the inner ring of the outer hub. The outer hub, the middle base and the thin sheet support frame are integrally formed.

[0005] This technical solution uses a hub base and a hub cover to facilitate the installation of airless tires. During installation, the airless tire is first installed on the hub base, and then the hub cover is fixedly installed on the hub base, so that the hub base and hub cover hold the airless tire in place, thus facilitating the installation of the airless tire.

[0006] Meanwhile, by setting an outer hub, a central base, and a thin-plate support frame, the structure of the hub base can be simplified, reducing the overall weight of the hub. A cylindrical sleeve-type mating seat is used to facilitate the insertion of the axle and the installation of the wheel. At the same time, an axle end cover mating seat is set to facilitate the installation of the axle cover. A limiting post is set to lock and limit the axle cover, and an end cover mounting hole is used to facilitate the fixing of the axle cover and the hub.

[0007] As a supplement to this technical solution, a cylindrical sleeve-shaped docking seat is provided at the center of the upper end face of the central base, and a shaft end cap docking seat is provided at the center of the lower end face of the central base. Several outwardly protruding limiting posts are evenly arranged on the outer ring of the shaft end cap docking seat, and an end cap mounting hole is provided at the lower end of each limiting post.

[0008] As a supplement to this technical solution, the two sides of the thin sheet support frame adopt an arc-shaped structure. By setting the arc-shaped structure, the transmission of supporting force is facilitated, and the overall structural strength is improved.

[0009] As a supplement to this technical solution, radial central reinforcing ribs are provided at the middle of the upper and lower end faces of the sheet support frame, and arc-shaped reinforcing ribs are provided at the edges of the upper and lower end faces of the sheet support frame. The structural strength of the sheet support frame is improved by providing radial central reinforcing ribs and arc-shaped reinforcing ribs.

[0010] As a supplement to this technical solution, a mating surface is provided at the middle of one end of the thin sheet support frame and the outer ring hub, and a connecting seat matching the mating surface is provided at the inner ring of the hub cover plate, and a mating bolt is installed between the mating surface and the connecting seat.

[0011] This technical solution improves the bonding strength between the outer wheel hub and the wheel hub base by setting a mating surface to facilitate close fitting with the wheel hub cover plate.

[0012] As a supplement to this technical solution, the thin sheet support frame extends in a fan-shaped structure on both sides near the outer ring hub and connects with the inner ring of the outer ring hub. The expanded extension improves the support strength of the thin sheet support frame connection.

[0013] Beneficial effects: This utility model relates to a split-type airless tire hub. By setting an outer hub, a central base, and a thin-plate support frame, the structure of the hub base can be simplified, reducing the overall weight of the hub. A cylindrical sleeve-type docking seat facilitates the insertion of the axle and the installation of the wheel. At the same time, an axle end cap docking seat facilitates the installation of the axle cap. A limiting post is set to lock and limit the axle cap, and an end cap mounting hole facilitates the fixing of the axle cap and the hub. It has the characteristics of low overall weight, convenient installation of airless tires, low production cost, convenient docking with axles, and high structural strength.
