Description

Technical Field

[0001] This utility model relates to the field of automobile wheel hub manufacturing technology, and more specifically, to a high-strength aluminum-iron composite anti-disc brake wheel hub structure. Background Technology

[0002] A wheel hub is a metal component on a car where the axle is mounted at the center of the wheel. Commonly known as a "wheel rim" or "steel rim," its main functions are to support the tire, transmit power, and bear the weight of the vehicle. It consists of a rim and spokes, and common materials include aluminum alloy and steel. As a critical safety component, wheel hubs must possess high strength and durability, while also affecting the vehicle's appearance and performance. When using existing wheel hubs for braking, the anti-disc brake discs often generate heat due to strong friction. However, the heat dissipation of existing anti-disc brake discs is limited. As a result, during long-term use, the anti-disc brake discs cannot dissipate heat quickly, and the high temperature will continue to accumulate, causing deformation or even damage, thus affecting the service life of the anti-disc brake discs.

[0003] Therefore, a high-strength aluminum-iron composite anti-disc brake hub structure is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a high-strength aluminum-iron composite anti-disc brake hub structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength aluminum-iron composite anti-disc brake hub structure, comprising a hub body, with a cast iron anti-disc brake disc fixedly connected to both ends of the hub body. Two annular connecting seats are symmetrically welded to the outer wall of the hub body. Multiple guide rail grooves are fixedly arranged at equal intervals on the surfaces of the two annular connecting seats. An inclined air inlet is opened at the end of each guide rail groove away from the anti-disc brake disc, and an air outlet facing the surface of the anti-disc brake disc is opened at the end of each guide rail groove near the anti-disc brake disc. Multiple anti-disc brake disc features are fixedly arranged on both inner side walls of the guide rail grooves. The micro-protrusions acting as airflow guides, with the width and depth of the guide rail grooves adapted to the inlet's tilt angle, allow air to be injected into the guide rail grooves as the hub rotates. The air enters through the inlet, forms an airflow within the guide rail grooves, and then exits through the outlet, directly guiding the airflow to the disc brake disc for air cooling. Multiple micro-protrusions are fixedly installed on the inner wall of the guide rail grooves. These micro-protrusions disrupt the laminar flow structure of the gas entering the guide rail grooves, making the airflow more turbulent, thereby improving the rapid heat dissipation effect on the disc brake disc and extending its service life.

[0006] Preferably, multiple threaded posts are evenly distributed at both ends of the wheel hub body, and the threaded posts are evenly distributed circumferentially along the end face of the wheel hub body. Multiple limiting members are fixedly connected to both ends of the wheel hub body and on the outer wall of the anti-disc brake disc. The setting of multiple limiting members can play a certain limiting role for the anti-disc brake disc.

[0007] Preferably, both of the reverse disc brake discs have multiple screw holes on their surfaces, and a screw is screwed into each of the screw holes. One end of the screw is screwed into a threaded post. After the screw is screwed in, a 0.5-1mm gap is left between the end of the screw and the bottom of the threaded post. Loosening is prevented by the elastic deformation of the anti-loosening washer. When installing and fixing the reverse disc brake disc, the screw can be threaded through the screw holes on the surface of the reverse disc brake disc, and then one end of the screw can be screwed into the threaded post fixedly connected to the wheel hub body to complete the fixed connection between the wheel hub body and the reverse disc brake disc.

[0008] Preferably, in order to dissipate heat from the disc brake disc, a center hole limiting plate is fixedly connected at the center shaft position of the disc brake disc. The surface of the center hole limiting plate is provided with multiple locking holes and multiple heat dissipation holes distributed on the surface of the center hole limiting plate. The outer wall of the disc brake disc is provided with multiple arc-shaped weight reduction and heat dissipation notches evenly distributed. The number of notches is adapted to the number of guide rail grooves. By setting the heat dissipation holes, the heat dissipation effect of the disc brake disc can be improved.

[0009] Preferably, the outer side wall of the hub body is symmetrically provided with two sets of spokes, and one end of the two spokes is connected to a rim. The two sets of spokes can support the rim and fix the hub body and the rim in a fixed connection.

[0010] Preferably, two retaining rings are symmetrically fixed on the outer wall of the rim, and a stepped valve stem protrusion adapted to the valve stem is provided on the rim, which facilitates the installation of the valve stem.

[0011] Preferably, in order to improve the strength and rigidity of the entire structure while achieving lightweighting, the wheel hub body, annular connecting seat, guide rail groove, spokes, rim, and retaining ring are all made of high-strength aluminum alloy, and the anti-disc brake disc is made of gray cast iron HT250. They are fixedly connected to the aluminum alloy wheel hub body by screws to form an aluminum-iron composite structure. The aluminum-iron composite structure effectively improves the strength and rigidity of the entire structure, enabling it to withstand greater loads and impacts. Furthermore, the use of aluminum reduces the weight of the entire structure, thereby improving the vehicle's handling and fuel economy.

[0012] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this high-strength aluminum-iron composite disc brake hub structure uses multiple guide rail grooves that are equidistantly connected to the surfaces of two annular connecting seats. When the hub body rotates, air is injected into the guide rail grooves. The air enters from the air inlet, forms an airflow in the guide rail grooves, and then exits from the air outlet. The airflow is then directly guided to the disc brake disc for air cooling. Furthermore, multiple micro-protrusions are fixedly installed on the inner wall of the guide rail grooves. These micro-protrusions disrupt the laminar flow structure of the air injected into the guide rail grooves, making the airflow more turbulent, thereby improving the rapid heat dissipation effect on the disc brake disc and extending its service life.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 As attached Figures 1 to 4The high-strength aluminum-iron composite anti-disc brake hub structure shown includes a hub body 1, with a cast iron anti-disc brake disc 2 fixedly connected to both ends of the hub body 1. Two annular connecting seats 11 are symmetrically welded to the outer wall of the hub body 1. Multiple guide rail grooves 12 are fixedly arranged at equal intervals on the surface of the two annular connecting seats 11. An inclined air inlet 13 is opened at the end of the multiple guide rail grooves 12 away from the anti-disc brake disc 2, and an air outlet 14 facing the surface of the anti-disc brake disc 2 is opened at the end of the multiple guide rail grooves 12 near the anti-disc brake disc 2. Multiple micro-protrusions 15 that play a turbulence role are fixedly arranged on the inner two side walls of the guide rail grooves 12. The groove width and depth of the guide rail grooves 12 are adapted to the inclination angle of the air inlet 13 to meet the airflow introduction requirements when the hub body 1 rotates, thereby improving the heat dissipation efficiency of the anti-disc brake disc 2.

[0020] Specifically, when the hub body 1 rotates, the entire structure can draw external air into the guide rail groove 12 through the air inlet 13. After forming an airflow in the guide rail groove 12, the airflow is discharged from the air outlet 14 and then directly guided to the reverse disc brake disc 2 for air cooling. Furthermore, multiple micro-protrusions 15 are fixedly installed on the inner wall of the guide rail groove 12. By setting the micro-protrusions 15, the laminar flow structure of the gas flowing into the guide rail groove 12 is disrupted, making the airflow more turbulent, thereby improving the rapid heat dissipation effect on the reverse disc brake disc 2 and extending the service life of the reverse disc brake disc 2.

[0021] Example 2 Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, multiple threaded posts 3 are evenly spaced at both ends of the wheel hub body 1. The threaded posts 3 are evenly distributed circumferentially along the end face of the wheel hub body 1. Multiple limiting members 4 are fixedly connected to both ends of the wheel hub body 1 and to the outer wall of the counter-disc brake disc 2. Multiple screw holes 8 are opened on the surface of both counter-disc brake discs 2. A screw 10 is screwed into each of the multiple screw holes 8, and one end of the screw 10 is screwed into the threaded post 3. After the screw 10 is screwed in, a gap of 0.5-1mm is left between the end of the screw 10 and the bottom of the threaded post 3. Loosening is achieved by the elastic deformation of the anti-loosening washer. When installing and fixing the counter-disc brake disc 2, the screw 10 can be threaded through the openings on the surface of the counter-disc brake disc 2. The screw hole 8 is then screwed into the threaded post 3 fixedly connected to the hub body 1, thus completing the fixed connection between the hub body 1 and the reverse disc brake disc 2. At the same time, the setting of multiple limiting parts 4 can play a certain limiting role for the reverse disc brake disc 2. In order to dissipate heat from the reverse disc brake disc 2, a center hole limiting plate 5 is fixedly connected at the center shaft position of the reverse disc brake disc 2. Multiple locking holes 6 are opened on the surface of the center hole limiting plate 5, and multiple heat dissipation holes 7 are distributed on the surface of the center hole limiting plate 5. Multiple arc-shaped weight reduction and heat dissipation notches 9 are evenly opened on the outer wall of the reverse disc brake disc 2. The setting of heat dissipation holes 7 can improve the heat dissipation effect of the reverse disc brake disc 2.

[0022] In a preferred embodiment, two sets of spokes 16 are symmetrically arranged on the outer side wall of the hub body 1. One end of the two spokes 16 is connected to a rim 17. Two retaining rings 18 are symmetrically fixed on the outer side wall of the rim 17. A stepped valve stem protrusion 19 adapted to the valve stem is provided on the rim 17. The two sets of spokes 16 can support the rim 17 and fix the hub body 1 and the rim 17. The valve stem protrusion 19 facilitates the installation of the valve stem.

[0023] As a preferred embodiment, in order to improve the strength and rigidity of the entire structure while achieving lightweighting, the wheel hub body 1, the annular connecting seat 11, the guide rail groove 12, the spoke 16, the wheel rim 17, and the retaining ring 18 are all made of high-strength aluminum alloy, and the anti-disc brake disc 2 is made of gray cast iron HT250. It is fixedly connected to the aluminum alloy wheel hub body 1 by screws 10 to form an aluminum-iron composite structure. The aluminum-iron composite structure effectively improves the strength and rigidity of the entire structure, enabling it to withstand greater loads and impacts. Furthermore, the use of aluminum reduces the weight of the entire structure, thereby improving the vehicle's handling and fuel economy.

[0024] The working process of this utility model is as follows: First, when the wheel rotates, it will drive the hub body 1 to rotate. When the hub body 1 rotates, the external air is injected into the guide rail groove 12 from the air inlet 13, and after forming an airflow in the guide rail groove 12, it is discharged from the air outlet 14. Then, the airflow is directly guided to the anti-disc brake disc 2, thereby cooling the anti-disc brake disc 2. In addition, multiple micro-protrusions 15 are fixedly arranged on the inner wall of the guide rail groove 12. By setting the micro-protrusions 15, the laminar flow structure of the gas injected into the guide rail groove 12 is disrupted, making the airflow more turbulent, thereby better cooling the guide rail groove 12. Furthermore, the overall shape of the guide rail groove 12 gradually tightens from the outside to the inside, that is, the cross-sectional area of ​​the air inlet 13 is larger than the cross-sectional area of ​​the air outlet 14. This makes the air injected from the air inlet 13 turbulent when flowing through the gradually decreasing space, thereby further improving the rapid heat dissipation effect on the anti-disc brake disc 2 and extending the service life of the anti-disc brake disc 2. The above is the working principle of this high-strength aluminum-iron composite anti-disc brake hub structure.
