Technical Field

[0001] The utility model relates to the technical field of wheels, in particular to a drum brake wheel. Background Art

[0002] A wheel hub is a cylindrical metal part that supports the tire inside the tire profile and is centered on the shaft.

[0003] At present, the drum brake wheel hubs applied to semi-trailers have no reinforcing belts and ribs, and there is a risk of fracture in actual use, and the safety factor is relatively low.

[0004] Therefore, we propose a drum brake wheel hub to solve the existing problems. Summary of the Utility Model

[0005] The purpose of the utility model is to propose a drum brake wheel hub for the problems existing in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A drum brake wheel hub includes a wheel hub body, a reinforcing belt, a flange and ribs. An anti-cracking sleeve is provided on the outer surface of the wheel hub body, and the flange is provided on the outer wall of the anti-cracking sleeve. The reinforcing belt is provided on the anti-cracking sleeve, and each rib is provided on the reinforcing belt, and the other end of the rib is provided on the surface of the anti-cracking sleeve.

[0007] Preferably, each convex block is equidistantly provided on the reinforcing belt, and each convex block is arranged in a circular array on the reinforcing belt, and each convex block is buried in the flange.

[0008] Preferably, an oil storage sleeve is rotatably provided inside the wheel hub body, and a storage space is formed between the circumferential surface of the oil storage sleeve and the inner wall of the wheel hub body.

[0009] Preferably, each mounting hole is provided on the flange, and each mounting hole is arranged in a circular array on the flange.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] During the use of the drum brake wheel hub of the utility model, the wheel hub connects the wheel and the shaft body, and is mainly a rotating component that bears the load between the wheel and the shaft. Its design adds a reinforcing belt and ribs, thereby improving the overall strength of the wheel hub, reducing the risk of wheel hub fracture, and improving the safety factor of the wheel hub during use.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0019] Embodiment 1

[0020] As Figures 1 - 4 shown, a drum brake hub proposed by the present utility model includes a hub body 1, a reinforcing band 3, a flange 5, and a reinforcing rib 6. An anti-cracking sleeve 2 is provided on the outer surface of the hub body 1, a flange 5 is provided on the outer wall of the anti-cracking sleeve 2, the reinforcing band 3 is provided on the anti-cracking sleeve 2, each reinforcing rib 6 is provided on the reinforcing band 3, and the other end of the reinforcing rib 6 is provided on the surface of the anti-cracking sleeve 2.

[0021] Based on Embodiment 1:

[0022] This hub connects the wheel and the shaft body, and is a rotating component that mainly bears the load between the wheel and the shaft. Its design adds a reinforcing band 3 and a reinforcing rib 6, thereby improving the overall strength of the hub, reducing the risk of hub fracture, and improving the safety factor of hub use.

[0023] Embodiment 2

[0024] As Figures 1 - 4 shown, a drum brake hub proposed by the present utility model, compared with Embodiment 1, this embodiment further includes: each bump 8 is equidistantly provided on the reinforcing band 3, each bump 8 is arranged in a circular array on the reinforcing band 3, and each bump 8 is buried inside the flange 5. Through the design of the bump 8, the connection strength between the reinforcing band 3 and the flange 5 is enhanced.

[0025] Inside the hub body 1, an oil storage sleeve 7 is rotatably provided. The space between the annular surface of the oil storage sleeve 7 and the inner wall of the hub body 1 is a storage space. Through the design of the oil storage sleeve 7, it is convenient for the hub to store lubricating oil and reduce the frequency of adding lubricating oil to the hub.

[0026] On the flange 5, each mounting hole 4 is provided. The mounting holes 4 are arranged in a circular array on the flange 5. Through the design of each mounting hole 4, it is convenient for the hub to be connected to the vehicle structure.
