Description

Technical Field

[0001] This utility model relates to the field of wheel hub insert technology, and in particular to a wheel hub insert. Background Technology

[0002] As an important component of automotive exterior decoration, wheel inserts are widely used to enhance the aesthetics and personalization of wheels. During actual assembly, wheel inserts must be tightly integrated with the wheel, meeting not only the mechanical requirements of vibration and centrifugal force during vehicle operation, but also balancing ease of installation and long-term stability. Their structural design directly affects the decorative effect and service life.

[0003] However, existing automotive wheel hub inserts have shortcomings. Traditional inserts often use simple clips or single-point contact for fixation, which easily leads to stress concentration. Under vehicle vibration, they may loosen or even fall off, affecting driving safety. Some inserts lack effective load-distribution structures, making them unable to withstand complex external forces, resulting in surface deformation and wear, and compromising the integrity of the decoration. In addition, existing inserts do not consider the dust problem during the manufacturing process. During processes such as spraying and cleaning, dust can easily accumulate on the inserts, affecting the fitting accuracy and aesthetics. Moreover, cleaning is cumbersome and maintenance costs are high, failing to meet the dual requirements of modern automobiles for the reliability and aesthetics of decorative parts. Summary of the Invention

[0004] To address the above issues, this application provides a wheel hub insert comprising an insert body, the insert body being fan-shaped in shape, a fixing unit being provided on the contact surface between the insert body and the wheel hub, the fixing unit comprising two fixing legs, a retaining platform being provided on the outer side of the two fixing legs, the retaining platform being arc-shaped on the contact surface with the wheel hub, a triangular support column being provided between the two fixing legs, and a support connecting plate being provided between the triangular support column and the fixing legs.

[0005] In one embodiment, the insert body has a pointed contact portion on the side near the center of the hub and an arc-shaped contact portion on the side away from the center of the hub. A guide groove penetrating the body is provided in the middle of the insert body, and the arc-shaped contact portion transitions to the bottom center of the guide groove.

[0006] In one embodiment, the insert body has a locking nut on the contact surface with the wheel hub, and the threaded hole of the locking nut is coaxial with the wheel hub locking hole.

[0007] In one embodiment, the insert body and the contact surface with the hub are provided with at least three reinforcing ribs, including two transverse reinforcing ribs and one radial reinforcing rib. The transverse reinforcing ribs and the radial reinforcing ribs are arranged in a cross pattern, and the two ends of one of the transverse reinforcing ribs are connected to the locking nut.

[0008] In one embodiment, a positioning support post is provided at the tip contact portion.

[0009] In one embodiment, both the fixing unit and the positioning support column are integrally formed with the insert body.

[0010] The beneficial effects of this utility model are as follows:

[0011] This application discloses a wheel hub insert, comprising an insert body and a fixing unit on the contact surface between the insert body and the wheel hub. The fixing unit includes two fixing feet, a retaining plate, a triangular support column, and a support connecting plate. During assembly, the insert body fits against the inner wall of the wheel hub via the arc-shaped retaining plate of the fixing unit. The curvature of the retaining plate matches the inner diameter of the wheel hub, enabling the insert body to form a surface-to-surface contact with the inner wall of the wheel hub. This eliminates stress concentration associated with traditional point contact. The load is transferred from the retaining plate to the fixing feet and then distributed to the triangular support column via the support connecting plate, effectively suppressing circumferential deformation of the insert body. Simultaneously, the rigid structure of the triangular support column counteracts lateral bending moments, ensuring uniform pressure distribution on the contact surface between the insert body and the wheel hub. In this application, by setting a fixed support foot with an arc-shaped mounting plate, the insert body and the inner wall of the wheel hub are made into surface-to-surface contact, eliminating the stress concentration problem; by setting a support connecting plate and a triangular support column, the load transmitted by the mounting plate is distributed, effectively suppressing the circumferential deformation of the insert body; and by using the triangular support column, the pressure on the contact surface between the insert body and the wheel hub is evenly distributed, enhancing the stability and reliability of the connection between the insert body and the wheel hub.

[0024] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0025] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0026] like Figure 1-3 As shown, a wheel hub insert includes an insert body 1, which is generally fan-shaped. A fixing unit 3 is provided on the contact surface between the insert body 1 and the wheel hub. The fixing unit 3 includes two fixing legs 31. A locking platform 32 is provided on the outer side of the two fixing legs 31. The contact surface between the locking platform 32 and the wheel hub is arc-shaped. A triangular support column 33 is provided between the two fixing legs 31. A supporting connecting plate 34 is provided between the triangular support column 33 and the fixing legs 31.

[0027] Specifically, the main body of the wheel hub insert is a fan-shaped insert body 1, and a fixing unit 3 is provided on its contact surface with the wheel hub 2. The fixing unit 3 consists of two fixing legs 31, and each fixing leg 31 has a locking platform 32 on its outer side. The contact surface between the locking platform 32 and the wheel hub is arc-shaped. During assembly, the insert body 1 fits against the inner wall of the wheel hub 2 through the arc-shaped locking platform 32 of the fixing unit 3. The curvature of the locking platform 32 matches the inner diameter of the wheel hub 2, so that the insert body 1 and the inner wall of the wheel hub 2 form a surface-to-surface contact, eliminating the stress concentration of traditional point contact. The load is transferred from the locking platform 32 to the fixing legs 31, and then distributed to the triangular support column 33 through the support connecting plate 34, effectively suppressing the circumferential deformation of the insert body 1. At the same time, the rigid structure of the triangular support column 33 offsets the lateral bending moment, ensuring that the pressure on the contact surface between the insert body 1 and the wheel hub 2 is evenly distributed. In this application, by setting a fixed support 31 with an arc-shaped mounting plate 32, the insert body 1 and the inner wall of the hub are made into surface-to-surface contact, eliminating the stress concentration problem; by setting a support connecting plate 34 and a triangular support column 33, the load transmitted by the mounting plate 32 is distributed, effectively suppressing the circumferential deformation of the insert body 1; by setting the triangular support column 33, the pressure on the contact surface between the insert body 1 and the hub 2 is evenly distributed, enhancing the stability and reliability of the connection between the insert body 1 and the hub 2.

[0028] A triangular support post 33 is installed between the two fixed legs 31. This triangular support post 33 is connected to the fixed legs 31 on both sides through a support connecting plate 34, forming a stable triangular support frame. By setting the triangular support post 33 and the support connecting plate 34, the locking platform 32 can maintain stable contact under different locking forces, avoiding surface deformation of the insert due to excessive locking force, and problems such as insecure fixing and abnormal noise due to insufficient locking force. The arc-shaped contact surface of the locking platform 32 increases the contact area, reduces local contact stress, and extends the service life of the insert and the hub.

[0029] like Figure 2 As shown, the insert body 1 has a pointed contact portion 11 on the side near the center of the hub 2 and an arc contact portion 12 on the side away from the center of the hub 2. A guide groove 4 penetrating the body is provided in the middle of the insert body 1, and the arc contact portion 12 is recessed towards the bottom center of the guide groove 4.

[0030] Specifically, the guide groove 4 penetrating the insert body 1 cooperates with the arc contact part 12 recessed at the bottom of the groove center, so that the dust generated by the insert during spraying can slide naturally along the guide groove 4, avoiding accumulation in the contact area, reducing dust cleaning and maintenance costs, and improving the spraying process.

[0031] like Figure 4 As shown, the insert body 1 has a locking nut 5 on the contact surface with the hub 2, and the threaded hole of the locking nut 5 is coaxial with the locking hole of the hub 2.

[0032] Specifically, a locking nut 5 is provided on the contact surface between the insert body 1 and the wheel hub 2. The threaded hole of the locking nut 5 is coaxial with the locking hole of the wheel hub 2, which can ensure that the locking nut 5 and the wheel hub locking hole are precisely connected, and at the same time ensure that the insert will not cause displacement or abnormal noise due to loosening of the nut during the operation of the wheel hub.

[0033] like Figure 3 , 4 As shown, the insert body 1 has at least three reinforcing ribs 13 on the contact surface with the wheel hub, including two transverse reinforcing ribs 131 and one radial reinforcing rib 132. The transverse reinforcing ribs 131 and the radial reinforcing rib 132 are arranged in a cross pattern. The two ends of one transverse reinforcing rib 131 are connected to the locking nut 5.

[0034] Specifically, the contact surface between the insert body 1 and the hub 2 is provided with two transverse reinforcing ribs 131 and one radial reinforcing rib 132 arranged in a cross pattern. One of the transverse reinforcing ribs 131 is connected to the locking nut 5 at both ends, which effectively improves the overall rigidity and deformation resistance of the insert body 1 and reduces the risk of structural damage caused by stress concentration. The transverse reinforcing rib 131 connected to the locking nut 5 can strengthen the local strength of the nut installation area and prevent the insert surface from denting or cracking due to uneven stress.

[0035] like Figure 3 As shown, a positioning support column 6 is provided at the tip contact portion 11.

[0036] Specifically, a positioning support post 6 is provided at the tip contact portion 11, which can accurately play a supporting role, effectively prevent the insert from sinking due to force during use, enhance the structural stability of the contact area between the insert and the wheel hub, ensure a tight fit and uniform force between the insert and the wheel hub, and thus improve the load-bearing capacity and service life of the insert.

[0037] like Figure 2 , 3 As shown, the fixing unit 3 and the positioning support column 6 are both integrally formed with the insert body 1.

[0038] Specifically, the fixing unit 3 and the positioning support column 6 are integrated with the insert body 1, avoiding the connection gaps and weak points caused by traditional splicing or assembly methods, eliminating the stress concentration and loosening hazards caused by loose joints between components, and greatly improving the overall structural strength and stability of the insert.

[0039] This application discloses a wheel hub insert, comprising an insert body 1. A fixing unit 3 is provided on the contact surface between the insert body 1 and the wheel hub. The fixing unit 3 includes two fixing legs 31, a mounting plate 32, a triangular support column 33, and a support connecting plate 34. During assembly, the insert body 1 fits against the inner wall of the wheel hub 2 via the arc-shaped mounting plate 32 of the fixing unit 3. The curvature of the mounting plate 32 matches the inner diameter of the wheel hub 2, allowing the insert body 1 to form a surface-to-surface contact with the inner wall of the wheel hub 2. This eliminates stress concentration associated with traditional point contact. The load is transferred from the mounting plate 32 to the fixing legs 31, and then distributed to the triangular support column 33 via the support connecting plate 34, effectively suppressing circumferential deformation of the insert body 1. Simultaneously, the rigid structure of the triangular support column 33 counteracts lateral bending moments, ensuring uniform pressure distribution on the contact surface between the insert body 1 and the wheel hub 2. In this application, by setting a fixed support 31 with an arc-shaped mounting plate 32, the insert body 1 and the inner wall of the hub are made into surface-to-surface contact, eliminating the stress concentration problem; by setting a support connecting plate 34 and a triangular support column 33, the load transmitted by the mounting plate 32 is distributed, effectively suppressing the circumferential deformation of the insert body 1; by setting the triangular support column 33, the pressure on the contact surface between the insert body 1 and the hub 2 is evenly distributed, enhancing the stability and reliability of the connection between the insert body 1 and the hub 2.
