Description

Technical Field

[0001] The invention relates to the technical field of wheel hub production, and in particular to a fatigue-resistant and long-life wheel hub and a production method thereof. Background Art

[0002] The car wheel, also known as the rim or wheel, is the metal part of the inner ring of the car tire. It is closely combined with the tire to support the weight of the vehicle and withstand various forces during driving. The design and material of the wheel directly affect the performance, safety and appearance of the vehicle. Modern car wheels are usually made of lightweight materials such as aluminum alloy, steel or magnesium alloy to reduce weight and improve fuel efficiency.

[0003] Wheel designs vary from simple multi-spoke designs to complex multi-piece wheels, each with specific functional and aesthetic considerations. Multi-spoke wheels are popular for their simple and classic look, while multi-piece wheels are favored by high-performance cars for their customizability and lightweight properties. The diameter and width of the wheel also affect the handling of the vehicle, with larger wheels generally providing better handling performance, but may also sacrifice some comfort.

[0004] In addition to appearance and performance, the durability and safety of the wheel are also very important. High-quality wheels can withstand the pressure of high-speed driving and intense driving, while poor-quality wheels may cause tire deflation or even wheel breakage, endangering driving safety. Therefore, choosing the right wheel is crucial to the overall performance and safety of the vehicle.

[0005] In actual wheel hub production, the rough wheel hub is obtained by casting with a mold, and then drilling, tapping and other steps are carried out, and then polishing, spray cleaning, drying and painting are carried out to finally obtain the finished wheel hub. However, since the wheel hub itself is formed by casting, its overall structure is one-piece. Once a car accident or collision occurs, the wheel hub will be severely deformed due to the impact. In this way, the entire wheel hub needs to be replaced. However, for a complete wheel hub, the replacement cost is high, which also shortens its service life.

[0006] Therefore, a fatigue-resistant and long-life wheel hub and a production method thereof are proposed to solve or alleviate the above problems. Summary of the invention

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0036] Furthermore, the terms “first”, “second”, “third”, etc. are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0037] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] A fatigue-resistant and long-life wheel hub, such as Figures 1 to 5 As shown, it includes a wheel hub 1 and two wheel hub frames fixedly connected to one end of the wheel hub 1 and symmetrically arranged. A mounting ring is integrally formed on the inner ring of one end of the wheel hub 1. The mounting ring is provided with a plurality of mounting holes penetrating along the thickness direction thereof. The wheel hub frame is provided with a plurality of connecting holes 6. The plurality of connecting holes 6 are axially arranged with the mounting holes, and connecting columns 7 are integrally formed in the connecting holes 6 and the mounting holes.

[0039] The wheel hub consists of a wheel hub 1 and two symmetrically arranged wheel hub frames. Although the wheel hub frames are connected together by connecting columns 7 formed by casting, when the wheel hub frames need to be disassembled and replaced, a conical tool can be used to align the position of the connecting columns 7, and high-pressure force can be used to knock or punch, so that the connecting columns 7 are separated from the connecting holes 6 and the mounting holes. Whether replacing the wheel hub 1 or the wheel hub frame, it is only necessary to align the new wheel hub 1 or the wheel hub frame with the other one to perform the connecting hole 6 and the mounting hole, and then cast the molten raw material. In this way, the installation and replacement of the two can be completed, and the structure of the entire wheel hub is more stable, and it is also convenient for installation and maintenance.

[0040] Preferably, the two wheel hub frames respectively include an outer wheel hub frame 2, an inner wheel hub frame 8, an outer connecting ring 5 located on the outer ring of the outer wheel hub frame 2, an inner connecting ring located on the outer ring of the inner wheel hub frame 8, an outer connecting column 4 integrally formed between the outer wheel hub frame 2 and the outer connecting ring 5, and an inner connecting column 9 integrally formed between the inner wheel hub frame 8 and the inner connecting ring, and a plurality of connecting holes 6 are opened on the inner connecting ring and the outer connecting ring 5.

[0041] The two wheel hub frames respectively include an outer wheel hub frame 2, an inner wheel hub frame 8, an outer connecting ring 5 located on the outer ring of the outer wheel hub frame 2, an inner connecting ring located on the outer ring of the inner wheel hub frame 8, an outer connecting column 4 integrally formed between the outer wheel hub frame 2 and the outer connecting ring 5, and an inner connecting column 9 integrally formed between the inner wheel hub frame 8 and the inner connecting ring. Therefore, during actual production, the two wheel hub frames can be obtained separately by mold casting, and the structures of the two wheel hub frames are relatively reliable. At the same time, the wheel hub ring 1 can also be limited by the wheel hub frame and will not be easily deformed.

[0042] Preferably, the wheel hub ring 1 , the inner connecting ring and the outer connecting ring 5 are provided with reinforcing defoaming ribs, and the inner wheel hub frame 8 and the inner connecting column 9 , the outer wheel hub frame 2 and the outer connecting column 4 are also provided with reinforcing defoaming ribs.

[0043] Reinforced de-bubble ribs are added inside the wheel hub ring 1 and the inner and outer connecting rings 5. These reinforced de-bubble ribs are also arranged in the inner wheel hub frame 8 and the inner and outer connecting columns 4. The function of the reinforced de-bubble ribs is to improve the strength and rigidity of the wheel hub and form a structure similar to reinforced concrete. At the same time, the design of the reinforced de-bubble ribs helps to remove bubbles in the molten material during the manufacturing process, thereby improving the quality and durability of the wheel hub.

[0044] Preferably, the reinforced defoaming ribs include a plurality of high temperature resistant rigid tubes 11 and a high temperature resistant hose 10 connecting adjacent high temperature resistant rigid tubes 11, both ends of the interior of the high temperature resistant rigid tubes 11 are fixedly connected with partitions 15, the partitions 15 are provided with through grooves and through grooves penetrating along the thickness direction thereof, a connecting bearing 18 is fixedly connected in the through groove, a hard connecting shaft 17 is fixedly connected to the inner ring of the connecting bearing 18, a shaking shaft 19 located in the high temperature resistant rigid tube 11 is fixedly connected between the two hard connecting shafts 17 on both sides, the distances from the edge of the shaking shaft 19 to the rotation axis thereof are different, and the shaking shaft 19 The outer peripheral wall of the high temperature resistant hard tube 11 can be set in conflict with the inner wall of the high temperature resistant hard tube 11, and the other end of the hard connection shaft 17 is fixedly connected to the soft connection shaft 13 located in the high temperature resistant hose 10, and a feed pipe 12 is commonly arranged in the high temperature resistant hard tubes 11 and the high temperature resistant hose 10, and the feed pipe 12 runs through the through groove, and the feed pipe 12 located in the high temperature resistant hard tube 11 is provided with a discharge hole 14 connected with the interior thereof on the outer peripheral wall, and the high temperature resistant hard tube 11 is provided with a plurality of through holes 16 connected with the interior thereof on the outer peripheral wall, and the sum of the flow rates of the plurality of through holes 16 is less than the flow rate of the feed pipe 12;

[0045] One end of the feed inlet of the feed pipe 12 is used for detachably connecting to a high-temperature pump body for feeding the molten raw material therein, and the flexible connection shaft 13 on the same side as the feed inlet of the feed pipe 12 is used for detachably connecting to a motor for driving the rotation thereof;

[0046] The high temperature resistant hose 10 is made of a multi-layer glass fiber coated cloth hose, and the feed pipe 12 and the high temperature resistant hard pipe 11 are made of 310S stainless steel.

[0047] When people need to inject molten raw materials into the mold, people only need to heat the raw materials through the high-temperature pump body and make the raw materials into a molten state. The molten raw materials are guided by the high-temperature pump body through the feed pipe 12 and pumped into the high-temperature resistant hose 10 and the high-temperature resistant hard tube 11. The molten raw materials will enter the high-temperature resistant hard tube 11 through the discharge hole 14 on the feed pipe 12, and then enter the cavity of the mold through the through hole 16 on the high-temperature resistant hard tube 11, so that the entire reinforced defoaming rib can be immersed in the molten raw materials. The flexible connecting shaft 13 is driven to rotate by starting the motor, so that the flexible connecting shaft 13 can drive the hard connecting shaft 17 to transmit, and the connecting bearing 18 effectively supports the hard connecting shaft 17, so that the shaking shaft 19 can intermittently conflict with the inner wall of the high-temperature resistant hard tube 11 at a high frequency, so that the entire reinforced defoaming ribs can vibrate continuously, and then the gas in the molten raw material in the mold can be shaken out by vibration, so as to prevent the hub frame and the hub ring 1 from affecting its structural strength due to the presence of bubbles.

[0048] The present invention also provides a method for producing a fatigue-resistant and long-life wheel hub, which is used to produce the above-mentioned fatigue-resistant and long-life wheel hub, such as Figure 6 As shown, the following steps are included:

[0049] Prepare materials, including aluminum, silicon, copper, magnesium, manganese, iron, titanium and zinc as raw materials according to the formula;

[0050] A reinforcing defoaming rib is placed in the wheel hub 1 mold, and the raw material is melted and stored and then injected into the wheel hub 1 mold. Bubbles in the molten raw material are removed by shaking the reinforcing defoaming rib and the wheel hub 1 is demoulded after cooling.

[0051] A reinforcing defoaming rib is placed in the hub frame mold, the raw material is melted and stored, and then injected into the hub frame mold. Bubbles in the molten raw material are removed by shaking the reinforcing defoaming rib, and the hub frame is demoulded after cooling.

[0052] Take a wheel hub 1 and two wheel hub frames for splicing, and after the connecting holes 6 of the wheel hub 1 and the wheel hub frames are aligned, inject molten raw materials to form a connecting column 7 to obtain a wheel hub blank;

[0053] The threaded hole 3 on the wheel hub blank is threaded, and the wheel hub blank is polished, cleaned, sprayed, and dried to obtain a finished wheel hub.

[0054] Preferably, the raw material includes 90% aluminum, 6% silicon, 2% copper, 0.5% magnesium, 0.2% manganese, and 1.3% iron, titanium, and zinc.

[0055] The above method can be used to produce a fatigue-resistant and long-life wheel hub, and the fatigue-resistant and long-life wheel hub can be spliced ​​between the hub rim 1 and the hub frame by mechanical automation or manual means after demolding. The wheel hub obtained in this way not only has good structural strength, but also can replace the hub rim 1 or the hub frame in the event of wheel hub deformation.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
