Description

Technical Field

[0001] This utility model relates to the field of lightweight heat-dissipating automotive wheel hub technology, specifically a lightweight heat-dissipating automotive wheel hub structure. Background Technology

[0002] In the structure of a car wheel hub, the hub body is the core load-bearing component. It not only bears the weight of the vehicle body but also enables real-time speed monitoring, providing crucial data for the braking system and effectively improving braking safety. The brake disc body is located inside the hub and fits tightly with the brake pads, generating resistance through friction to achieve braking. Its material is mostly gray cast iron or carbon ceramic. After wear, the braking performance will drop significantly and must be replaced in time. The hub cap covers the center of the hub, serving both a decorative purpose, making the hub look more beautiful, and protecting the interior from dust and moisture intrusion, protecting bolts and bearings. It also features brand logos, enhancing vehicle recognition.

[0003] The excessive weight of existing wheel hubs is a major problem. Heavier wheels require vehicles to consume more energy to overcome their inertia during driving, leading to a significant increase in energy consumption, which runs counter to the current demand for energy conservation and emission reduction. At the same time, excessive weight reduces the vehicle's handling agility, making steering sluggish and affecting driving precision and safety. Moreover, excessive wheel hub weight also limits the improvement of the overall vehicle performance, making it difficult to achieve breakthroughs in key performance indicators such as acceleration and braking, which is not conducive to the development of the automotive industry towards high performance and high efficiency. Therefore, we need a lightweight and heat-dissipating automotive wheel hub structure. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight heat-dissipating automotive wheel hub structure to solve the problems mentioned in the background art, such as the excessive weight of existing wheel hubs, which leads to increased vehicle energy consumption, limited handling agility, and difficulty in improving overall performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight heat-dissipating automobile wheel hub structure, comprising a wheel hub body, characterized in that: a heat dissipation component is integrally connected to the outer wall of the wheel hub body, a lightweight component is welded to one side of the wheel hub body, bolts are provided inside the lightweight component, the lightweight component includes a wheel hub cover, and the wheel hub cover is welded to one side of the wheel hub body, a hollow frame is welded inside the wheel hub cover, a hollow groove is opened inside the hollow frame, and wheel hub heat dissipation holes are opened inside the hollow frame.

[0006] Preferably, there are multiple hollow slots, and the multiple hollow slots are evenly distributed in a ring around the center of the hollow frame.

[0007] Preferably, the heat dissipation holes of the wheel hub are evenly distributed on the hollow frame for heat dissipation.

[0008] Preferably, the heat dissipation assembly includes a brake disc body, one side of which is integrally connected to the outer wall of the wheel hub body. An air duct is provided inside the brake disc body, a brake disc heat dissipation hole is provided on one side of the brake disc body, heat dissipation fins are welded to one side of the wheel hub body, and heat dissipation grooves are provided on the outer wall of the wheel hub body.

[0009] Preferably, the air duct increases the heat dissipation surface area of ​​the brake disc body, and there are multiple air ducts, which are evenly distributed in a ring around the center of the brake disc body.

[0010] Preferably, the brake disc body has multiple brake disc heat dissipation holes distributed on its surface. These holes are arranged in a ring around the center of the brake disc, and the heat dissipation holes between adjacent ring arrays are misaligned in both the radial and circumferential directions.

[0011] Preferably, the heat dissipation fins are made of a metal with high thermal conductivity.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In the scheme of this application: 1. To address the problem of excessive wheel weight in existing technologies, which leads to increased vehicle energy consumption, limited handling agility, and difficulty in improving overall performance, this application cleverly optimizes the wheel structure by setting up a hollow frame and carefully creating hollow slots on it. These hollow slots, through reasonable layout and design, effectively reduce the amount of material used in the wheel while ensuring that the wheel has sufficient structural strength to stably bear the weight of the vehicle and various forces during driving, thus achieving the goal of lightweight wheel. This not only helps to reduce vehicle energy consumption and improve handling agility, but also provides strong support for optimizing the overall performance of the vehicle. 2. To address the problem in existing technologies where the surface temperature of the brake disc rises sharply during high-speed friction, resulting in low heat dissipation efficiency and a decline in braking performance and thermal damage, this application addresses this issue by incorporating an internal air duct to create an internal fan effect that accelerates the exchange of hot air. This generates negative pressure at the edges of the brake disc's heat dissipation holes, actively drawing in cool air and creating airflow circulation. Simultaneously, heat dissipation fins transfer heat from the brake disc body to the wheel hub body, and then the heat is dissipated to the surrounding environment through convective heat exchange between the air and the heat dissipation grooves of the wheel hub body. This significantly improves the overall heat dissipation efficiency of the brake disc, effectively reducing its temperature, ensuring stable braking performance, and extending its service life.

[0015] 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.

[0016] This utility model embodiment provides a lightweight heat-dissipating automotive wheel hub structure, such as Figure 1 and Figure 4 As shown, the wheel hub includes a main body 1, with a heat dissipation component 2 integrally connected to the outer wall of the main body 1. A lightweight component 3 is welded to one side of the main body 1, and bolts 4 are installed inside the lightweight component 3. The lightweight component 3 includes a wheel cover 301, which is welded to one side of the main body 1. A hollow frame 302 is welded inside the wheel cover 301, with a hollow groove 303 and a wheel hub heat dissipation hole 304 inside the hollow frame 302. The hollow groove 303 on the hollow frame 302 reduces the overall weight of the wheel hub while ensuring sufficient structural strength, and also indirectly allows the wheel hub to dissipate heat. The wheel hub heat dissipation hole 304 on the hollow frame 302 is a direct channel for heat dissipation, allowing hot air to be quickly discharged from the wheel hub, effectively reducing the temperature of the wheel hub and brake disc body 201.

[0017] Furthermore, such as Figure 4 As shown, there are multiple hollow grooves 303, and the multiple hollow grooves 303 are evenly distributed in a ring around the center of the hollow frame 302. By setting the hollow grooves 303, the weight of the wheel hub can be reduced, and at the same time, the stress can be dispersed by using the geometric shape to avoid the decrease in rigidity caused by weight reduction.

[0018] Furthermore, such as Figure 4As shown, the hub heat dissipation holes 304 are evenly distributed on the hollow frame 302 for heat dissipation. The hub heat dissipation holes 304 allow airflow to be guided more efficiently through the hub heat dissipation holes 304 when the brake disc rotates, thereby improving heat dissipation efficiency.

[0019] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the heat dissipation assembly 2 includes a brake disc body 201, which is annular. One side of the inner ring of the brake disc body 201 is integrally connected to the outer wall of the wheel hub body 1. An air duct 202 is provided inside the brake disc body 201, and a brake disc heat dissipation hole 203 is provided on one side of the brake disc body 201. A heat dissipation fin 204 is welded to one side of the wheel hub body 1, and a heat dissipation groove 205 is provided on the outer wall of the wheel hub body 1. When the brake disc body 201 is working, it generates intense friction, causing the surface temperature to rise sharply. The air duct 202 inside the brake disc body allows airflow to enter from the center and flow radially to form an internal fan effect, accelerating the replacement of hot air on the surface and allowing hot air to leave the surface of the brake disc more quickly. This creates a negative pressure zone at the edge of the brake disc heat dissipation hole 203, actively drawing in cool air and forming a continuous airflow circulation, which improves the efficiency of hot air replacement. At the same time, the heat from the brake disc body 201 is conducted to the wheel hub body 1 through the heat dissipation fin 204, and then dissipated to the surrounding environment through convection heat exchange between the air and the heat dissipation groove 205 of the wheel hub body 1, achieving overall heat dissipation.

[0020] Furthermore, such as Figure 2 As shown, the air duct 202 can increase the heat dissipation surface area of ​​the brake disc body 201, and there are multiple air ducts 202. The multiple air ducts 202 are evenly distributed in a ring around the center of the brake disc body 201. Through the air ducts 202, airflow can enter from the center of the brake disc body 201 and flow along the radial channel to form an internal fan effect. The air duct 202 increases the heat dissipation surface area of ​​the brake disc body 201.

[0021] Furthermore, such as Figure 2 As shown, multiple brake disc heat dissipation holes 203 are distributed on the surface of the brake disc body 201. The multiple brake disc heat dissipation holes 203 are arranged in a ring around the center of the brake disc, and the brake disc heat dissipation holes 203 between adjacent ring arrays are misaligned in both the radial and circumferential directions. By setting multiple brake disc heat dissipation holes 203, thermal stress can be dispersed to the periphery of multiple holes, reducing local stress concentration.

[0022] Furthermore, such as Figure 3 As shown, the heat dissipation fins 204 are made of a metal with high thermal conductivity. Through the heat dissipation fins 204, the heat dissipation fins 204 can quickly transfer the heat generated by the brake disc body 201 to the wheel hub body 1.

[0023] Working principle: The tire is mounted on the wheel hub via bolt 4, and the tire is fixed by rotating the nut. During braking, the surface temperature of the brake disc body 201 rises sharply. The internal air duct 202 allows airflow to enter from the center of the brake disc body 201 and flow radially, creating an internal fan effect. This accelerates the replacement of hot air on the surface of the brake disc body 201, allowing the hot air to leave the brake disc surface more quickly. This creates a negative pressure zone at the edge of the brake disc cooling holes 203, actively drawing in surrounding cool air and forming a continuous airflow circulation. This further accelerates the hot air replacement efficiency, effectively reducing the temperature of the brake disc body 201. The temperature of the brake disc body 201 is conducted through the heat dissipation fins 204, allowing heat to be transferred to the wheel hub body 1. Through convective heat exchange between the air and the heat dissipation grooves of the wheel hub body 1, the heat is dissipated into the surrounding environment, thereby achieving a heat dissipation effect on the entire brake disc. The hollow slots 303 on the hollow frame 302 reduce the overall weight of the wheel hub while ensuring sufficient structural strength, and also indirectly dissipate heat from the wheel hub. The wheel hub heat dissipation holes 304 on the hollow frame 302 are direct channels for heat dissipation, allowing hot air to be quickly discharged from the inside of the wheel hub, effectively reducing the temperature of the wheel hub and the brake disc body 201.
