Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a cylindrical wheel hub. Background Technology

[0002] In the automotive, construction machinery and other fields, cylindrical wheel hubs are core load-bearing components, and their performance directly affects the stability of equipment operation and the cost of use.

[0003] Traditional cylindrical wheel hubs typically consist of a rim, a hub, and several spokes. The spokes are distributed circumferentially along the inner side of the rim, and their ends are usually welded to the inner wall of the rim and the hub at the center of the hub to transfer loads. In practical applications, it has been found that when the wheel hub is subjected to external impact (such as hitting an obstacle while driving), one or a few spokes are prone to deformation and breakage. Because the spokes are welded to the rim and hub, disassembly and replacement require cutting the weld points, which is complex and time-consuming. Secondary welding may also damage the original structural strength of the wheel hub, making it difficult to guarantee performance after repair. In most cases, users have to scrap the entire wheel hub, resulting in material waste and increased usage costs. Therefore, we propose a cylindrical wheel hub to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A cylindrical wheel hub includes: a rim, wherein a locking block is fixedly arranged in an annular array in the middle of the inner wall of the rim;

[0006] A support disc is slidably embedded inside the rim. The center of the support disc has a central hole. The sides of the support disc have a ring array of slots that are adapted to a locking block. The support disc has a rectangular channel on the side of the slot. The side wall of the rectangular channel is threaded with a locking bolt extending into the slot. The end of the locking block has a connecting hole adapted to the locking bolt.

[0007] Furthermore, the number of the card blocks and card slots is greater than or equal to four.

[0008] Furthermore, a fan-shaped channel is constructed between the sides of the support disk and the sides of the slot.

[0009] Furthermore, the surface of the support disk has heat dissipation holes evenly distributed on the side of the central hole.

[0010] Furthermore, both the card block and the card slot are in the shape of an isosceles trapezoid.

[0011] Furthermore, the connection port is funnel-shaped.

[0012] Furthermore, the outer end face of the rim is constructed with triangular notches arranged in a ring along the circumferential direction.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model adopts an integrated support disc to replace the traditional split wheel spokes and hub core, reducing welding nodes (traditionally, multiple sets of wheel spokes need to be welded at both ends), simplifying the processing technology. At the same time, the integrated structure improves the overall support strength and avoids the risk of fracture caused by welding stress concentration. In addition, the detachable structure with a card block, card slot and locking bolt is adopted, which can realize the disassembly and assembly of the support disc without cutting the weld points, effectively solving the problem that traditional wheel hub repair requires damage to the original structure, and has high practicality.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] This application provides a cylindrical wheel hub, primarily addressing the problem that in existing technologies, when a wheel hub is subjected to external impact (such as hitting an obstacle while driving), one or a few spokes are prone to deformation and breakage. Because the spokes are welded to the rim and hub core, disassembly and replacement require cutting the weld points, which is complex and time-consuming; secondary welding may also damage the original structural strength of the wheel hub, leading to unreliable performance after repair. The application provides the following technical solution, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0022] A cylindrical wheel hub, comprising:

[0023] The rim 1 has a ring array of locking blocks 2 fixedly arranged in the middle of its inner wall;

[0024] A support disc 3 is slidably embedded inside the rim 1. The center of the support disc 3 has a central hole 301. The side of the support disc 3 has a ring array of slots 302. The slots 302 are adapted to the locking block 2. The support disc 3 has a rectangular channel 303 on the side of the slot 302. The side wall of the rectangular channel 303 is threaded with a locking bolt 4 extending into the slot 302. The end of the locking block 2 has a connecting hole 201 adapted to the locking bolt 4.

[0025] Workflow Description

[0026] Assembly process

[0027] Align the support disc 3 with the inner axis of the rim 1, so that the slot 302 of the support disc 3 corresponds one-to-one with the block 2 on the inner wall of the rim 1. Slowly slide the support disc 3 along the axial direction until the slot 302 is completely fitted onto the block 2 to complete the initial positioning. Tighten the locking bolt 4 to make it embed into the connecting hole 201 until the torque is up to standard, ensuring that the rim 1 and the support disc 3 are not loose. The assembly is complete.

[0028] Disassembly and repair process

[0029] If the support disc 3 needs to be replaced, use the appropriate tool to unscrew all the locking bolts 4. After removing the locking bolts 4, push the support disc 3 in the opposite direction along the axis to separate the slot 302 from the block 2. Slide the damaged support disc 3 out of the rim 1, take the new support disc 3 and repeat the assembly process. After the replacement is completed, reinstall the tire to restore the wheel hub's functionality.

[0030] This cylindrical wheel hub uses an integrated support disc 3 to replace the traditional split spokes and hub core, reducing welding nodes (traditionally, multiple spokes need to be welded at both ends), simplifying the processing technology. At the same time, the integrated structure improves the overall support strength and avoids the risk of fracture caused by welding stress concentration. In addition, the detachable structure with a locking block 2, a slot 302, and a locking bolt 4 allows the support disc 3 to be disassembled and assembled without cutting the weld points, effectively solving the problem that traditional wheel hub repair requires damaging the original structure.

[0031] like Figure 3 As shown, in some embodiments, the number of locking blocks 2 and locking slots 302 is greater than or equal to four. More specifically, from the perspective of force, the circular array design of more than four locking blocks 2 can evenly transfer the external load (such as impact and gravity) borne by the rim 1 to the support disc 3, avoiding local stress concentration due to insufficient quantity, reducing the risk of deformation and breakage, which is superior to the traditional single-point force mode of wheel spokes. In addition, from the perspective of positioning, more than four locking blocks 2 can ensure that the rim 1 and the support disc 3 are radially precisely fitted without relative offset, maintaining a rigid whole, and can be quickly aligned during disassembly and assembly, ensuring assembly efficiency and stability.

[0032] like Figure 4As shown, in some embodiments, a fan-shaped channel 304 is constructed between the sides of the support disk 3 and the sides of the slot 302. More specifically, the fan-shaped structure distributed in a ring array can reduce the amount of material used and the weight of the wheel hub, while dispersing the force on the support disk 3, avoiding local stress concentration, and ensuring load-bearing performance. Compared with the traditional spoke structure, this design achieves both lightweighting to reduce the energy consumption of equipment operation and maintaining structural reliability, making it suitable for the high-intensity use requirements of automobiles and construction machinery.

[0033] like Figure 4 As shown, in some embodiments, heat dissipation holes 305 are evenly distributed on the surface of the support disc 3 on the side of the central hole 301. More specifically, when the wheel hub is running, friction easily generates local heat. The heat dissipation holes 305 can accelerate air circulation and quickly remove heat, avoiding high temperature causing component aging or performance degradation. The evenly distributed layout can ensure heat dissipation without dead corners and prevent local overheating damage. At the same time, the heat dissipation holes 305 are opened on the side of the central hole 301, avoiding core stress areas such as the card slot 302. While achieving efficient heat dissipation, the load-bearing strength of the support disc 3 is not weakened, balancing heat dissipation performance and structural reliability, and extending the overall service life of the wheel hub.

[0034] like Figure 3 As shown, in some embodiments, both the locking block 2 and the locking slot 302 are isosceles trapezoids. More specifically, from an assembly perspective, the trapezoidal symmetrical structure can quickly guide the locking block 2 and the locking slot 302 to align, avoiding misalignment and simplifying the assembly process. Moreover, the contact area of ​​the trapezoidal inclined surface is larger than that of the plane, making it more stable after fitting and reducing the risk of radial displacement. From a stress perspective, the trapezoidal structure can distribute and transfer impact loads along the inclined surface, avoiding stress concentration caused by the "corner stress" of the traditional rectangular structure, reducing the probability of deformation and breakage of the locking block 2 or the locking slot 302. At the same time, the trapezoidal structure can be disassembled and assembled without jamming, ensuring the convenience of replacing the support disc 3, which is in line with the overall detachable design concept.

[0035] like Figure 3 As shown, in some embodiments, the port of the connecting hole 201 is funnel-shaped. More specifically, from an operational perspective, the funnel-shaped port forms a flared guide structure that can quickly guide the insertion of the locking bolt 4 without repeated alignment adjustments, greatly improving bolt installation efficiency. This is especially suitable for on-site maintenance scenarios. From a structural protection perspective, the funnel-shaped design can prevent the bolt from being misaligned and scratching the inner wall threads of the connecting hole 201 during insertion, extending the service life of the component. At the same time, the funnel-shaped port also provides a certain amount of space for bolt removal during disassembly, further conforming to the overall design concept of being detachable and easy to maintain, ensuring operational convenience.

[0036] like Figure 2As shown, in some embodiments, the outer end face of the rim 1 is constructed with triangular notches 101 arranged in a ring along the circumferential direction. More specifically, the core function of the circumferential array of triangular notches 101 on the outer end face of the rim is to provide a leverage point for tire removal. When removing tires from a traditional rim 1, tools are prone to slipping, while the triangular notches 101 allow tools such as pry bars to be precisely inserted, quickly separating the tire from the rim 1 and reducing the difficulty of operation. At the same time, the ring array distribution can ensure that the rim 1 is subjected to balanced force and avoid strength loss caused by local gaps. Moreover, the notch design is compatible with the detachable characteristics of the support disc 3, and the support disc 3 can be directly exposed after tire removal, shortening the overall maintenance process and conforming to the design concept of convenient wheel hub maintenance.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
