Abstract
Description
Technical Field
[0001] This utility model belongs to the field of truck wheel technology, and in particular relates to a truck wheel with good heat dissipation. Background Technology
[0002] Currently, most truck and bus wheel hubs use round or rectangular air vents, which can meet basic heat dissipation requirements, but have three major drawbacks: First, under heavy loads, stress concentration is easily generated at the edges of the air vents, leading to fatigue cracks and shortening the life of the wheel hub; Second, the traditional air vent shape has limited effect on improving the overall rigidity of the wheel hub. When dealing with the impact of heavy loads from trucks and buses, insufficient rigidity will cause wheel hub deformation, affecting driving stability; Third, the chamfers of traditional air vents are mostly single-radius rounded corners, which are not combined with the optimization of the air vent shape, resulting in poor stress dispersion and easy accumulation of mud, sand, stones and other debris, which can block the air vents and affect heat dissipation. Summary of the Invention
[0003] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a truck wheel with good heat dissipation, including a hub body, characterized in that it further includes: Heart-shaped air vents: Several heart-shaped air vents are evenly distributed circumferentially on the hub body; A chamfer is provided at the connection between the heart-shaped air vent and the wheel hub body, and the chamfer is provided along the contour curve of the heart-shaped air vent; The inner contour of the heart-shaped air vent is transitioned by a circular arc.
[0004] Furthermore, the width of the heart-shaped air vent is narrower on the side closer to the center of the wheel hub body, and the width of the heart-shaped air vent gradually increases radially towards the side further away from the center of the wheel hub body.
[0005] Furthermore, at least 10 heart-shaped air vents are provided.
[0006] Furthermore, the chamfer forms a 45-degree angle with the surface of the wheel hub body.
[0007] Furthermore, it also includes: The valve stem opening is located on the wheel hub body.
[0008] Furthermore, it also includes: The main shaft bore is located at the center of the hub body; The mounting holes are numerous and are evenly distributed circumferentially around the spindle hole.
[0009] Furthermore, both the wheel hub body and the heart-shaped air vents have anti-corrosion coatings.
[0010] The beneficial effects of this utility model are as follows: 1. Effectively disperses stress at the edge of the air vents, preventing fatigue cracks during heavy-load driving, while optimizing airflow path to improve heat dissipation and extend wheel life.
[0011] 2. To avoid the reduction in rigidity caused by excessive reduction of materials in the core area, the wider vents on the outside can enhance airflow and further improve heat dissipation efficiency, making it suitable for the high-efficiency use requirements of heavy-duty trucks.
[0012] 3. The design minimizes wheel deformation when subjected to heavy truck impacts, resulting in greater driving stability. Additionally, the multi-vent design further enhances heat dissipation uniformity, preventing localized overheating.
[0013] 4. Precise control of the chamfer angle effectively reduces stress concentration while minimizing the accumulation of debris such as mud, sand, and stones at the chamfer, thus preventing blockage of the ventilation holes and affecting heat dissipation.
[0014] 5. It can be adapted to conventional valve stems without additional modifications to the main structure of the wheel hub, simplifying the assembly process. At the same time, the reasonable hole design avoids affecting the overall rigidity and heat dissipation of the wheel hub.
[0015] 6. Ensures a stable connection between the wheel hub and the axle, ensuring efficient power transmission. At the same time, the evenly distributed mounting holes disperse connection stress and improve connection reliability under heavy load conditions.
[0016] 7. Extends the service life of wheels under complex road conditions, reduces problems such as decreased rigidity and blocked heat dissipation channels caused by rust, and lowers maintenance costs. Attached Figure Description

[0018] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In the description of this application, it should be noted that the terminology used herein is only for describing specific implementations and is not intended to limit the exemplary implementations according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings indicate similar items, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings. Example 1
[0019] This embodiment provides a truck wheel with good heat dissipation, including a hub body 1, characterized in that it further includes: Heart-shaped air holes 2: Several heart-shaped air holes 2 are evenly distributed circumferentially on the hub body 1; Chamfer 3: A chamfer 3 is provided at the connection between the heart-shaped air hole 2 and the hub body 1. The chamfer 3 is provided along the contour curve of the heart-shaped air hole 2. The inner contour of the heart-shaped air vent 2 is transitioned by a circular arc.
[0020] In this technical solution, the inner contour of the heart-shaped air vent 2 is transitioned by an arc, and the chamfer 3 along the contour curve can avoid stress concentration caused by the right angle or single arc structure of traditional air vents. At the same time, the evenly distributed air vents can ensure air circulation efficiency and meet the heat dissipation requirements of heavy-duty truck scenarios.
[0021] Meanwhile, the curved structure of the heart-shaped air hole 2 is composed of multiple R arcs of different sizes, and the chamfer 3 is opened along the curve of the heart shape, thereby guiding the stress to be evenly distributed along the curve. Compared with the traditional circular air hole, the heart-shaped air hole 2 and the chamfer 3 reduce the stress concentration at the edge of the air hole, effectively prevent the generation of fatigue cracks under heavy load, and improve the fatigue life of the wheel hub. The inner contour of the heart-shaped air vent 2 is transitioned by a rounded arc to avoid sharp corners inside the heart-shaped air vent 2; This structural design effectively disperses the stress at the edge of the air vents, preventing fatigue cracks during heavy-load driving, while optimizing the airflow path to improve heat dissipation and extend wheel life. Example 2
[0022] This embodiment provides a truck wheel with good heat dissipation. In addition to the technical solutions of the above embodiments, it also has the following technical features.
[0023] Furthermore, the heart-shaped air vent 2 is narrower on the side closer to the center of the wheel hub body 1, and the width of the heart-shaped air vent 2 gradually increases radially towards the side of the heart-shaped air vent 2 away from the center of the wheel hub body 1.
[0024] In this technical solution, the design of the air vents of this shape reduces the material weakening of the core stress area of the wheel hub body 1 while maintaining sufficient heat dissipation area. It balances lightweight and structural rigidity, achieving a dual improvement in rigidity and lifespan, which meets the "heavy load and high efficiency" usage requirements of trucks and buses.
[0025] Meanwhile, since the chamfer 3 is opened along the curve of the heart-shaped air hole 2, the design of being larger on the outside and smaller on the inside makes it difficult for debris such as mud and stones to stay at the edge of the air hole. Compared with the traditional rounded corner, it reduces the accumulation of debris, avoids the blockage of the air hole, and ensures the stability of heat dissipation performance. This structural design avoids the reduction in rigidity caused by excessive material reduction in the core area, while the wider vents on the outside can enhance airflow and further improve heat dissipation efficiency, making it suitable for the heavy-duty and high-efficiency use requirements of trucks. Example 3
[0026] This embodiment provides a truck wheel with good heat dissipation. In addition to the technical solutions of the above embodiments, it also has the following technical features.
[0027] Furthermore, at least 10 heart-shaped air vents 2 are provided.
[0028] In this technical solution, the uniform circumferential distribution of 10 or more heart-shaped air holes 2 can optimize the force path of the hub spokes, avoid local overload, and improve the overall torsional rigidity and bending rigidity.
[0029] This structural design allows the wheel hub to deform less when subjected to heavy truck impacts, resulting in higher driving stability. At the same time, the multi-vent design further improves heat dissipation uniformity and avoids localized overheating. Example 4
[0030] This embodiment provides a truck wheel with good heat dissipation. In addition to the technical solutions of the above embodiments, it also has the following technical features.
[0031] Furthermore, the chamfer 3 forms a 45-degree angle with the surface of the hub body 1.
[0032] In this technical solution, the 45-degree chamfer angle 3 angles are optimized to maximize the dispersion of stress at the edge of the air hole, while avoiding problems such as increased processing difficulty and increased risk of debris accumulation caused by excessively large or small angles, thus balancing stress dispersion effect and processing feasibility.
[0033] This structural design allows for precise control of the chamfer angle 3, effectively reducing stress concentration while minimizing the accumulation of debris such as mud and stones at the chamfer angle 3, thus preventing air vent blockage and affecting heat dissipation. Example 5
[0034] This embodiment provides a truck wheel with good heat dissipation. In addition to the technical solutions of the above embodiments, it also has the following technical features.
[0035] Furthermore, it also includes: Valve stem hole 4 is located on the wheel hub body 1.
[0036] In this technical solution, the addition of valve hole 4 provides an adapter structure for the installation of tire valve, meeting the basic usage requirements of truck tire inflation and air pressure monitoring, and ensuring the practicality of the wheel.
[0037] This structural design allows for the adaptation of conventional valve stems without requiring additional modifications to the main wheel hub structure, simplifying the assembly process. At the same time, the reasonable hole design avoids affecting the overall rigidity and heat dissipation of the wheel hub. Example 6
[0038] This embodiment provides a truck wheel with good heat dissipation. In addition to the technical solutions of the above embodiments, it also has the following technical features.
[0039] Furthermore, it also includes: Main shaft hole 5, which is located at the center of hub body 1; Mounting holes 6 are provided, and the mounting holes 6 are evenly distributed circumferentially around the spindle hole 5.
[0040] In this technical solution, the spindle hole 5 is used for precise assembly with the truck axle (the axle and assembly method are existing technologies and will not be described in detail here), and the evenly distributed mounting holes 6 ensure that the wheel hub and the axle are firmly connected and the force is balanced, avoiding driving vibration caused by assembly deviation.
[0041] This structural design ensures a stable connection between the wheel hub and the axle, guaranteeing efficient power transmission. At the same time, the evenly distributed mounting holes disperse connection stress, improving connection reliability under heavy load conditions. Example 7
[0042] This embodiment provides a truck wheel with good heat dissipation. In addition to the technical solutions of the above embodiments, it also has the following technical features.
[0043] Furthermore, both the wheel hub body 1 and the heart-shaped air vent 2 have anti-corrosion coatings.
[0044] In this technical solution, the anti-corrosion coating can resist the erosion of rainwater, mud, salt and other media during truck operation, prevent the wheel hub body 1 and the heart-shaped air hole 2 from rusting, and ensure the stability of structural strength and heat dissipation performance.
[0045] This structural design extends the service life of wheels under complex road conditions, reduces problems such as decreased rigidity and blocked heat dissipation channels caused by rust, and lowers maintenance costs.
