Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive wheel hub technology, and in particular to high-strength lightweight automotive wheel hubs. Background Technology
[0002] A car wheel rim, also known as a wheel hub, rim, wheel, or rim, is a cylindrical metal component that supports the tire from within. It is mounted on the axle. The main function of the wheel rim is to support the car body and is an important component for transmitting the weight of the car body to the road. It also bears the lateral load, driving force, and braking torque during cornering. The condition of the wheel rim directly affects whether the car can drive normally and its safety during driving.
[0003] A lightweight, high-strength automotive wheel hub is disclosed in Chinese utility model patent publication number CN222329366U. The wheel hub body includes a rim and a hub axle. A support shaft is provided on the hub axle, and multiple slots are provided on the support shaft. A first spoke is provided in the slot, and the first spoke is hollow. A second spoke and a fixing ring are provided on the first spoke. The second spoke is Y-shaped. The front of the fixing ring is fixedly connected to the back of the first spoke, which has beneficial effects.
[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In the above-mentioned device, the fixing ring and the wheel rim are connected to each other by a second nut and a screw. This not only increases the mass of the wheel hub itself, but also, due to the large weight of the car, the screw is easily deformed during the rotation of the wheel hub, thus affecting the normal driving of the car. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a high-strength, lightweight automotive wheel hub.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-strength lightweight automotive wheel hub, comprising a wheel hub body, the wheel hub body including a rim, a wheel axle hub and multiple connecting spokes, the wheel axle hub being located at the center of the rim, the wheel axle hub coinciding with the axis of the rim, the two ends of the multiple connecting spokes being fixed to the wheel axle hub and the rim respectively, multiple mounting holes being provided through the side wall of the wheel axle hub, the rim, wheel axle hub and connecting spokes being an integrated design, and multiple mounting grooves being provided on the side wall of the wheel axle hub.
[0007] By adopting the above technical solution, when using the wheel hub, workers install the wheel hub body onto the car's drive shaft through the mounting holes. During this process, because the rim, axle hub, and connecting spokes are integrated, the strength of the wheel hub body itself is increased, thereby reducing the probability of deformation during use and thus reducing the likelihood of the car becoming malfunctioning. Furthermore, the mounting slot reduces the weight of the wheel hub body.
[0008] Furthermore, a connecting piece is provided at the end of the connecting spoke away from the wheel hub, the connecting piece is fixed to the inner ring of the rim, and a connecting groove is provided through the connecting piece.
[0009] By adopting the above technical solution, by Figure 1 As shown, the connecting piece increases the contact area between the connecting spokes and the rim, thereby further increasing the strength of the wheel hub itself. This reduces the probability of deformation during use, and consequently, the probability of the vehicle becoming malfunctioning. The connecting groove reduces the weight of the connecting piece, which in turn reduces the weight of the wheel hub itself.
[0010] Furthermore, the connecting spokes include a first connecting member fixedly disposed on the outer wall of the wheel hub and a second connecting member fixedly disposed on the outer wall of the wheel hub, wherein the ends of the first connecting member and the second connecting member away from the rim are fixed to the adjacent connecting piece.
[0011] By adopting the above technical solution, by Figure 1 As shown, the distance between the first connector and the second connector gradually decreases from the end closer to the wheel hub to the end closer to the wheel rim. Because triangles have stability, this further increases the strength of the wheel hub itself, thereby reducing the probability of deformation during use and thus reducing the probability of the car being unable to drive normally.
[0012] Furthermore, connecting strips are fixedly provided on the sidewalls of the first and second connecting members that are far apart from each other, and the other ends of the multiple connecting strips are fixed to the inner ring of the wheel rim.
[0013] By adopting the above technical solution, the connecting strip further improves the connection strength of the wheel hub body, thereby reducing the probability of deformation of the wheel hub body during use.
[0014] Furthermore, the wheel hub body is made of titanium alloy, the connecting strip is made of titanium alloy, and the wheel hub body, connecting strip, and connecting strip are integrally formed by 3D printing.
[0015] By adopting the above technical solutions, titanium alloys possess the characteristics of being lightweight and high-strength, thereby improving the strength of the wheel hub body and reducing its weight, thus enhancing the practicality of the wheel hub. The wheel hub body, connecting pieces, and connecting strips, manufactured through 3D printing in a single piece, further improve the stability of the connection between them, thereby further reducing the probability of deformation of the wheel hub body during use.
[0016] Furthermore, the diameter of the mounting groove gradually decreases from the inside to the outside, and an elastic pad is fixedly installed inside the mounting groove.
[0017] Furthermore, the elastic pad is made of polypropylene, and the outer diameter of the elastic pad matches the inner diameter of the mounting groove.
[0018] By adopting the above technical solution, when workers install the wheel hub body, they can further improve the stability of the wheel hub body installation by setting protrusions on the drive shaft that match the mounting groove, thereby improving the stability of the device. An elastic pad made of polypropylene fills the gap between the protrusion and the mounting groove, thus reducing the probability of noise generated by the wheel hub colliding with the protrusion during rotation, thereby improving the stability of the device.
[0019] Furthermore, a connecting hole is provided on the side wall of the axle hub, and a connecting ring is fixedly provided on the inner wall of the connecting hole, and the axis of the connecting hole coincides with the axis of the axle hub.
[0020] By adopting the above technical solution, the connecting hole further reduces the weight of the wheel hub body, and the connecting ring set inside the connecting hole reduces the difficulty for workers to install the brand logo. During installation, workers only need to snap the logo and the connecting ring together, thereby reducing the difficulty of the workers' work.
[0021] Furthermore, the mounting holes are provided in a plurality of circular arrays on the side wall of the axle hub, and the distance between the axis of the plurality of mounting holes and the axis of the axle hub is equal.
[0022] By adopting the above technical solution, the distance between the axis of the multiple mounting holes and the axis of the wheel hub is reduced to be equal, so that the wheel hub body can be connected to the car drive shaft more stably, thereby improving the stability of the wheel hub body during use.
[0023] Furthermore, the surfaces of the wheel hub body, connecting piece, and connecting strip are all electroplated.
[0024] By adopting the above technical solution, the wear resistance and corrosion resistance of the wheel hub body, connecting pieces and connecting strips are improved through electroplating, thereby extending the service life of the wheel hub.
[0025] In summary, this utility model has the following beneficial effects:
[0026] 1. In this application, when the wheel hub body is in use, the worker installs the wheel hub body onto the vehicle drive shaft through the mounting holes. During this process, because the rim, axle hub, and connecting spokes are integrated into a single design, the strength of the wheel hub body itself is increased, thereby reducing the probability of deformation during use and thus reducing the probability of the vehicle being unable to drive normally. In addition, the mounting slot reduces the weight of the wheel hub body;
[0027] 2. In this application, by Figure 1As shown, the connecting piece increases the contact area between the connecting spokes and the rim, thereby further increasing the strength of the wheel hub itself. This reduces the probability of deformation during use, and consequently, the probability of the vehicle malfunctioning. The connecting groove reduces the weight of the connecting piece, thus reducing the weight of the wheel hub itself.
[0028] 3. In this application, by Figure 1 As shown, the distance between the first connector and the second connector gradually decreases from the end closer to the wheel hub to the end closer to the wheel rim. Because triangles have stability, this further increases the strength of the wheel hub itself, thereby reducing the probability of deformation during use and thus reducing the probability of the car being unable to drive normally.

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0035] like Figure 1-4As shown in the figure, this application discloses a high-strength lightweight automotive wheel hub, including a wheel hub body, a connecting piece 3, a connecting strip 4, an elastic pad 5, and a connecting ring 61. The wheel hub body 1 includes a rim 11, a wheel hub 12, and multiple connecting spokes 13. The wheel hub 12 is located at the center of the rim 11, and the axis of the wheel hub 12 coincides with that of the rim 11. Multiple connecting spokes 13 are provided, and the two ends of the multiple connecting spokes 13 are respectively fixed to the wheel hub 12 and the rim 11. Multiple mounting holes 2 are provided through the side wall of the wheel hub 12. The rim 11, wheel hub 12, and connecting spokes 13 are integrated into one piece, and multiple mounting grooves 21 are provided on the side wall of the wheel hub 12.
[0036] When in use, the wheel hub body 1 is installed onto the vehicle's drive shaft through the mounting holes 2. During this process, because the rim 11, axle hub 12, and connecting spokes 13 are integrated into one piece, the strength of the wheel hub body 1 itself is increased, thereby reducing the probability of deformation during use and thus reducing the probability of the vehicle being unable to drive normally. In addition, the mounting slot 21 reduces the weight of the wheel hub body 1.
[0037] The connecting piece 3 is located at the end of the connecting spoke 13 away from the wheel hub 12. The connecting piece 3 is fixed to the inner ring of the rim 11, and a connecting groove 31 is provided through the connecting piece 3.
[0038] Depend on Figure 1 As shown, the connecting piece 3 increases the contact area between the connecting spoke 13 and the rim 11, thereby further increasing the strength of the wheel hub body 1 itself, reducing the probability of deformation during use, and thus reducing the probability of the car failing to drive normally. The connecting groove 31 reduces the weight of the connecting piece 3, thereby reducing the weight of the wheel hub body 1.
[0039] The connecting spoke 13 includes a first connecting member 131 and a second connecting member 132. The first connecting member 131 is fixedly disposed on the outer wall of the wheel hub 12, and the second connecting member 132 is fixedly disposed on the outer wall of the wheel hub 12. The ends of the first connecting member 131 and the second connecting member 132 away from the rim 11 are fixed to the adjacent connecting piece 3.
[0040] Depend on Figure 1 As shown, the distance between the first connector 131 and the second connector 132 gradually decreases from the end closer to the wheel hub 12 to the end closer to the wheel rim 11. Because triangles have stability, this further improves the strength of the wheel hub body 1 itself, thereby reducing the probability of deformation during use and thus reducing the probability of the car being unable to drive normally.
[0041] Multiple connecting strips 4 are provided and fixedly installed on the side walls of the first connecting member 131 and the second connecting member 132 that are far apart from each other, and the other ends of the multiple connecting strips 4 are fixed to the inner ring of the rim 11.
[0042] The connecting strip 4 further improves the connection strength of the wheel hub body 1, thereby reducing the probability of deformation of the wheel hub body 1 during use.
[0043] To further reduce the probability of deformation of the wheel hub body 1 during use, the wheel hub body 1 is made of titanium alloy, and the connecting strip 4 is also made of titanium alloy. The wheel hub body 1, connecting piece 3, and connecting strip 4 are integrally formed by 3D printing. Titanium alloy is lightweight and high-strength, which improves the strength of the wheel hub body 1 and reduces its weight, thereby improving the practicality of the wheel hub. The integral 3D printing of the wheel hub body 1, connecting piece 3, and connecting strip 4 further improves the stability of the connection between them, thereby further reducing the probability of deformation of the wheel hub body 1 during use.
[0044] The diameter of the mounting groove 21 gradually decreases from the inside to the outside. The elastic pad 5 is fixedly installed in the mounting groove 21. The elastic pad 5 is made of polypropylene and its outer diameter matches the inner diameter of the mounting groove 21.
[0045] When the worker installs the wheel hub body 1, the stability of the installation of the wheel hub body 1 is further improved by setting a protrusion on the drive shaft that matches the mounting groove 21, thereby improving the stability of the device. The elastic pad 5 made of polypropylene fills the gap between the protrusion and the mounting groove 21, thereby reducing the probability of noise caused by the wheel hub colliding with the protrusion during rotation, thus improving the stability of the device.
[0046] A connecting hole 6 is provided on the side wall of the wheel hub 12, and a connecting ring 61 is fixedly installed on the inner wall of the connecting hole 6, and the axis of the connecting hole 6 coincides with the axis of the wheel hub 12.
[0047] The connecting hole 6 further reduces the weight of the wheel hub body 1. The connecting ring 61 set inside the connecting hole 6 reduces the difficulty for workers to install the brand logo. During installation, workers only need to engage the logo with the connecting ring 61, thereby reducing the difficulty of the workers' work.
[0048] To improve the stability of the wheel hub body 1 during use, multiple mounting holes 2 are arranged in a circumferential array on the side wall of the wheel hub 12, and the distance between the axis of the multiple mounting holes 2 and the axis of the wheel hub 12 is equal. The equal distance between the axis of the multiple mounting holes 2 and the axis of the wheel hub 12 allows the wheel hub body 1 to be connected to the vehicle drive shaft more stably, thereby improving the stability of the wheel hub body 1 during use.
[0049] To extend the service life of the wheel hub, the surfaces of the wheel hub body 1, connecting piece 3, and connecting strip 4 are all electroplated. Electroplating improves the wear resistance and corrosion resistance of the wheel hub body 1, connecting piece 3, and connecting strip 4, thereby extending the wheel hub's service life.
[0050] The working principle of the high-strength lightweight automotive wheel hub in this embodiment is as follows: When in use, the wheel hub body 1 is installed onto the vehicle's drive shaft through the mounting holes 2. During this process, because the rim 11, axle hub 12, and connecting spokes 13 are integrated into a single design, the strength of the wheel hub body 1 itself is increased, thereby reducing the probability of deformation during use and thus reducing the probability of the vehicle being unable to drive normally. In addition, the mounting groove 21 reduces the weight of the wheel hub body 1.
[0051] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
