Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a vehicle wheel hub. Background Art

[0002] The cylindrical component with the inner profile of the tire supporting the tire and the center mounted on the shaft is called a wheel hub. The wheel hubs in the prior art mainly include aluminum alloy wheel hubs and steel wheel hubs. Aluminum alloy wheel hubs are made of special alloy materials, which have the advantages of light weight, good heat dissipation and high aesthetics. However, compared with steel wheel hubs, they are more easily deformed.

[0022] The technical solutions 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 only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Embodiment 1, as attached Figure 2 , Attachment Figure 3 and attached Figure 4 shown.

[0024] A vehicle wheel hub comprises a rim 1 and a spoke 2, wherein the spoke 2 is welded to the inner side of the rim 1, and is characterized in that an annular groove 3 is provided on the inner and outer end surfaces of the rim 1, a reinforcement support ring 4 is provided in the annular groove 3, the reinforcement support ring 4 is detachably connected to the annular groove 3, and the reinforcement support ring 4 is made of a metal material having a higher rigidity than aluminum alloy.

[0025] The outer surface of the reinforcement support ring 4 is provided with reinforcement ribs 5 .

[0026] It is worth noting that, as a preferred material, the reinforcement support ring 4 is made of alloy steel.

[0027] Through the above structure, the reinforcement support ring 4 is more rigid and less likely to deform when squeezed, which can increase the support strength and compressive strength of the wheel hub and make it less likely to deform. After the reinforcement support ring 4 has been used for a long time, small cracks may appear on it, affecting its performance. Regular replacement of the reinforcement support ring 4 can maintain the performance of the wheel hub.

[0028] Embodiment 2, as attached Figure 2 , Attachment Figure 3 and attached Figure 4 shown.

[0029] A plurality of threaded columns 6 are welded on the inner wall of the annular groove 3 , and a through hole 7 is correspondingly provided on the reinforcement support ring 4 . The threaded columns 6 pass through the through hole 7 and are matched with a fastening nut 8 .

[0030] The annular groove 3 is provided with limiting protrusions 9 on its inner and outer circumferences, and the reinforcing support ring 4 is provided with limiting notches 10 on its inner and outer side walls, and the limiting protrusions 9 can pass through the limiting notches 10 .

[0031] The outer wall of the reinforcement support ring 4 is also provided with a plurality of limiting grooves 11 . The limiting grooves 11 are arranged on one side of the limiting notch 10 , and the limiting protrusions 9 can be inserted into the limiting grooves 11 .

[0032] It is worth noting that the through hole 7 on the reinforcement support ring 4 is an arc-shaped hole.

[0033] Through the above structure, the limiting notch 10 on the reinforcement support ring 4 is aligned with the limiting protrusion 9 and then pressed to make it enter the annular groove 3, and then the reinforcement support ring 4 is rotated to make the limiting protrusion 9 fit into the limiting notch 10, thereby ensuring that the reinforcement support ring 4 fits tightly against the inner wall of the annular groove 3, so that the installation is tightened, and the fastening nut 8 is tightened to fix the reinforcement support ring 4.

[0034] Embodiment 3, as attached Figure 1 , Attachment Figure 2 and attached Figure 3 shown.

[0035] The inner and outer end surfaces of the rim 1 are also provided with dust cover rings 12 , which cover the outer side of the reinforcement support ring 4 , and the dust cover ring 12 is detachably connected to the outer end surface of the rim 1 .

[0036] Two clamping rings 13 are provided on the inner and outer end surfaces of the rim 1 corresponding to the dust cover ring 12, and a clamping groove 14 is provided on the side where the two clamping rings 13 are close to each other. The inner and outer sides of the dust cover ring 12 are provided with clamping ridges 15, and the dust cover ring 12 is made of elastic material, and the clamping ridges 15 are clamped in the clamping grooves 14.

[0037] It is worth noting that the dust cover ring 12 is preferably made of rubber.

[0038] Through the above structure, the setting of the dust cover ring 12 can prevent dust from entering the annular groove 3, avoiding the entry of dust causing the reinforcement support ring 4 to not fit tightly against the inner wall of the annular groove 3, and can also prevent dust from entering the limiting protrusion 9 and affecting its clamping with the limiting groove 11.

[0039] The specific method of use is as follows: replace the reinforcement support ring 4 and press the dust cover ring 12 to deform it, so that the snap-fitting ridges 15 are separated from the snap-fitting ring 13, unscrew the fastening nut 8, rotate the reinforcement support ring 4 to align the limiting protrusion 9 with the limiting notch 10, and then remove it; during installation, align the limiting notch 10 on the reinforcement support ring 4 with the limiting protrusion 9 to snap the reinforcement support ring 4 into the annular groove 3, rotate the reinforcement support ring 4 to make the limiting notch 10 and the limiting protrusion 9 staggered, at this time the limiting protrusion 9 is snapped into the limiting groove 11, and then the fastening nut 8 can be tightened.

[0040] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
