Description

Technical Field

[0001] The utility model relates to the technical field of wheel production, in particular to a wheel hub of an anti-puncture tire. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machinery. They have different types due to their different uses. Car puncture-proof tires are one of them. They are usually installed on metal wheels, can support the car body, buffer external impacts, achieve contact with the road surface and ensure the vehicle's driving performance.

[0003] The wheel hubs of existing automobile puncture-proof tires are usually produced by means of turning ring forgings. After the turning process, the utilization rate of the wheel hub steel is generally too low, resulting in a waste of materials and increasing the production cost.

[0004] Therefore, the utility model provides a wheel hub for puncture-proof tires to meet the demand. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a wheel hub for puncture-proof tires by setting a head, a middle section and a tail, so that the stepped design of the head increases the structural strength; the thickness of the middle section is reduced, the material distribution is optimized, and the waste of material is avoided, and the b-angle connection between the head and the middle section is convenient for quick disassembly and assembly of the puncture-proof tire; and the b-angle arc transition design between the tail and the middle section is used to enhance the structural strength, reduce the redundant material part, and increase the stability of the device. The integrated design of the head, the middle section and the tail makes the structure of the entire wheel hub more compact, reduces the structural materials, and increases the material utilization rate to more than 90%. The above settings can solve the problem that the existing technology mostly adopts turning of ring forgings and turning of thick steel plates after hot pressing to produce in actual work, resulting in generally too low material utilization rate, resulting in waste of materials and increased production costs.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A puncture-proof tire hub comprises a main body, a spoke wheel is fixedly connected to the interior of one side of the main body, the profile of the main body comprises a head at one end, a middle section in the middle and a tail at the other end, the head, the middle section and the tail are an integrated structure, and a plurality of raised ribs are fixedly connected to the inner wall of the main body.

[0008] Optionally, the top of the head near the middle section is stepped.

[0009] Optionally, the middle section is connected to the head at an angle b, and an inner groove is provided on the outer side of the middle section.

[0010] Optionally, the tail portion and the middle section are transitioned by a bevel arc at an angle b, and a connecting slope is provided on the inner side of the tail portion away from one end of the middle section.

[0011] Optionally, the raised ribs are distributed in an S shape on the inner wall of the middle section, and the cross-section of the raised ribs is a trapezoid.

[0012] Optionally, a trapezoidal cavity is provided on the contact surface between the middle section and the raised rib.

[0013] Optionally, the trapezoidal cavity and the bottom of the corresponding raised rib form a buffer cavity, and the cross-section of the buffer cavity is hexagonal.

[0014] Optionally, a side of the spoke wheel close to the tail is fixedly connected to the connecting slope.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, by setting the head, middle section and tail, the stepped design of the head increases the structural strength; the thickness of the middle section is reduced, the material distribution is optimized, and the waste of material is avoided. The b-angle connection between the head and the middle section facilitates the rapid disassembly and assembly of the puncture-proof tire; and the b-angle arc transition design between the tail and the middle section enhances the structural strength, reduces the redundant material part, and increases the stability of the device. The integrated design of the head, middle section and tail makes the structure of the entire wheel hub more compact, reduces the structural materials, and increases the material utilization rate to more than 90%.

[0017] By opening an inner groove on the outer side of the middle section, it is not only convenient to fix the tire, but also the thickness of the material is reduced through reasonable layout, which further saves material and reduces material cost. By opening a connecting slope on the inner side of the tail, it is convenient to install it with the spoke wheel through the connecting slope, which improves the assembly efficiency of the device and reduces the difficulty of work.

[0018] By arranging raised ribs and trapezoidal cavities on the inner wall of the middle section, the raised ribs strengthen the structural strength of the hub, especially strengthen the strength of the thinner middle section, so that the entire hub is stronger when subjected to gravity and impact force, and is not prone to deformation or breakage. In addition, the raised ribs are reasonably designed without excessively increasing material consumption, thereby achieving an optimal balance between material and performance. The design of the trapezoidal cavity enables a more reasonable distribution of materials, which not only optimizes the utilization efficiency of the material, but also forms an effective cavity structure by combining with the bottom of the raised rib, which helps to disperse and reduce stress concentration, thereby enhancing the local strength and overall stability of the hub.

[0032] like Figures 1 to 3 As shown, an embodiment of the utility model provides a puncture-proof tire hub, including a main body 1, the profile of the main body 1 includes a head 3 at one end, a middle section 4 in the middle and a tail 5 at the other end, the head 3, the middle section 4 and the tail 5 are an integrated structure, and the top of the head 3 close to the middle section 4 is stepped; the stepped design of the head 3 increases the strength of the main body 1, and at the same time, in the process of sleeved tire on the outside of the main body 1, there is no need to process the prying edge, which reduces the working steps and improves the working efficiency, the thickness of the middle section 4 is reduced, the weight of the material is reduced, and the material cost is saved.

[0033] like Figures 1 to 4 As shown, the middle section 4 is connected to the head 3 at an angle b, an inner groove 7 is provided on the outer side of the middle section 4, and the tail 5 and the middle section 4 are transitioned by an inclined arc at an angle b; the angle b is 4°±1°, and the tire is inserted from the curved side of the head 3. With the curved surfaces set at both ends of the head 3, the tire is easier to insert into the head 3. Through the inclined angle b between the head 3 and the middle section 4, the tire is easier to slide and be installed on the outer side of the main body 1. The inner groove 7 allows the tire to be stuck on the outer side of the middle section 4, thereby increasing the stability of the tire.
