Description

Technical Field

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

[0002] Wheel hub structures that enhance wheel stability typically have the following characteristics: First, they are made of high-strength materials, which can withstand greater pressure and impact, ensuring no deformation under complex road conditions. Second, they have optimized spoke design, such as using a reasonable number, shape, and layout of spokes, which helps to evenly distribute the load and improve overall rigidity. Third, they have precise manufacturing processes to ensure the dimensional accuracy and roundness of the hub body, reducing eccentricity and vibration during rotation, thereby enhancing wheel stability.

[0003] The hub body, through the rationally designed spokes, evenly distributes the ground force transmitted from the tire, making the wheel bear the force evenly, reducing local overload. The high-strength and high-precision manufactured hub body can maintain its own shape, reduce rotational imbalance caused by deformation, and ensure smooth wheel rotation.

[0004] In existing technologies, the stability of some traditional wheel hubs gradually becomes a problem when dealing with complex working conditions. At high speeds, due to poor aerodynamic design, airflow turbulence causes unnecessary vibration and resistance in the wheel, which consumes energy and affects handling. Therefore, a wheel hub structure that enhances wheel stability is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wheel hub structure that enhances wheel stability, aiming to improve the problem of unnecessary vibration and resistance in wheels in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wheel hub structure for enhancing wheel stability includes a hub body, with multiple spokes fixedly connected to the outer side of the hub body in an annular arrangement. Multiple aerodynamic grooves are formed inside the spokes. Two aerodynamic plates are fixedly connected to the outer side of the spokes. Multiple fixing holes are formed in an annular arrangement inside the hub body. A central locking hole is formed inside the hub body. Multiple positioning pins are fixedly connected in an annular arrangement on the rear side of the hub body. Multiple portable components for facilitating heat dissipation of the hub body during driving are formed inside the hub body.

[0008] As a further description of the above technical solution:

[0009] The portable component includes a through hole, and multiple guide rings are fixedly connected to the front side of the hub in an annular arrangement. Heat dissipation fins are fixedly connected to the inner wall of the hub.

[0010] As a further description of the above technical solution:

[0011] A rim is fixedly connected to one of the far sides of the plurality of spokes, and a tire is provided on the outside of the rim;

[0012] As a further description of the above technical solution:

[0013] The rear side of the guide ring is in contact with the inner wall of the front side of the through hole, and the outer side of the heat dissipation fins is in contact with the inner wall of the through hole.

[0014] As a further description of the above technical solution:

[0015] The turbulence groove is trapezoidal in shape, and the external of the plurality of through holes is formed inside the hub body;

[0016] As a further description of the above technical solution:

[0017] The spoiler is arc-shaped and made of carbon fiber.

[0018] As a further description of the above technical solution:

[0019] The guide ring is wedge-shaped and made of engineering plastic.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the spoiler groove accelerates airflow by utilizing the characteristics of a large opening and a narrow closing, the spoiler plate guides the direction of airflow, and the positioning post on the rear side of the hub body, together with the fixing hole and the center locking hole, thereby achieving the optimization of aerodynamics by relying on the spoiler groove and the spoiler plate, effectively reducing air resistance and energy loss, and greatly enhancing the stability and handling of the wheel during driving.

[0029] 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.

[0030] Reference Figures 1 to 3 This utility model provides an embodiment of a wheel hub structure that enhances wheel stability, including a hub body 1. The hub body 1 provides support for the entire structure and serves as a carrier connecting other vehicle components to the tire 12. It is used to transmit the vehicle's power to the tire 12 and bear the vehicle's weight. Multiple spokes 2 are fixedly connected to the outer ring of the hub body 1. The spokes 2 play an important role in force transmission and support, and can transmit force evenly and stably to the hub body 1, and then distribute it to the entire vehicle structure, effectively ensuring the stability of the wheel under various driving conditions. Multiple airflow grooves 3 are opened inside the spokes 2. When air flows through the spokes 2, it guides the air to flow along a specific path. Due to the large opening of the trapezoidal groove, it can efficiently capture air. As the air flows into the groove, the narrowing part of the groove will accelerate the airflow speed, thereby forming a specific airflow disturbance around the spokes 2, which helps to reduce air resistance, reduce energy loss during vehicle operation, and enhance air convection.

[0031] Two externally fixed spoilers 4 are attached to the spokes 2. The arc-shaped spoilers 4 utilize aerodynamic principles to precisely guide the airflow around the spokes 2 at high speeds. When air impacts the arc-shaped spoilers 4, it is forced to change direction and flow along the arc surface of the spoilers 4, thus forming a stable and efficient airflow channel in a specific area of ​​the spokes 2. The spoilers 4 and the spoiler grooves 3 work together to further optimize the aerodynamic environment around the spokes 2, enhancing the stability and handling of the wheels during driving. Multiple fixing holes 5 are arranged in a ring inside the hub 1. These fixing holes 5 are mainly used to connect the hub 1 to the vehicle's brake system using bolts and other connecting components. The drum, wheel hub bearing housing, and other components are tightly fixed together. The hub body 1 has a central locking hole 6 inside, which tightly locks the hub body 1 to the vehicle axle at the central locking hole 6. The central locking can provide more precise concentricity and reduce wheel imbalance caused by installation errors. In conjunction with the fixing hole 5, it can significantly improve the stability and rotation accuracy of the wheel when driving at high speed. Multiple positioning pins 7 are fixedly connected in a ring on the rear side of the hub body 1. When the hub body 1 is close to the vehicle installation part, it can be quickly inserted into the pre-designed positioning hole or positioning groove, providing preliminary precise guidance for the installation of the hub body 1. The hub body 1 has multiple portable components inside to facilitate heat dissipation of the hub body 1 during driving.

[0032] Reference Figure 3 and Figure 4 The portable component includes a through hole 8, which is used for air circulation to dissipate heat from the heat dissipation fins 10. Multiple guide rings 9 are fixedly connected to the front side of the hub 1 in a ring. When the vehicle is traveling at high speed, the air is guided by the guide rings 9 and is introduced into the through hole 8 at a specific angle and speed to form a directional airflow channel to quickly dissipate heat from the heat dissipation fins 10. The heat dissipation fins 10 are fixedly connected to the inner wall of the hub 1. By increasing the heat dissipation area, the heat generated inside the hub 1 is quickly conducted to the surrounding air.

[0033] Reference Figures 2 to 4 A rim 11 is fixedly connected to the far side of multiple spokes 2. The rim 11 is the component that directly contacts and mounts the tire 12. The tire 12 is set on the outside of the rim 11. The tire 12 serves as the contact medium between the vehicle and the road surface. The rear side of the guide ring 9 contacts the inner wall of the front side of the through hole 8. The airflow guided by the guide ring 9 can enter the through hole 8, providing a stable and continuous airflow source for the subsequent heat dissipation process. The outer side of the heat dissipation fins 10 contacts the inner wall of the through hole 8. When the airflow guided by the guide ring 9 passes through the through hole 8, the high-speed flowing air fully contacts the heat dissipation fins 10. Under the action of convective heat transfer, the heat on the surface of the heat dissipation fins 10 is quickly carried away, thereby achieving an efficient heat dissipation process.

[0034] The spoiler 3 is trapezoidal in shape. During vehicle operation, when air flows over the wheel spokes 2, the larger opening can efficiently capture the surrounding air. As the air flows into the slot, the trapezoidal opening gradually narrows. According to fluid dynamics principles, the narrowing of the channel leads to an increase in air velocity. Multiple through holes 8 are externally located inside the hub 1, which provides space for the through holes 8. The spoiler 4 is arc-shaped. When the vehicle is traveling at high speed, when air impacts the arc-shaped spoiler 4, it is forced to change its flow direction due to the arc surface of the spoiler 4. The diffuser 4 features an arc-shaped flow pattern. The material of the diffuser 4 is carbon fiber, which allows the diffuser 4 to maintain its structural integrity even when subjected to the strong impact of high-speed airflow, without deformation or damage. The guide ring 9 is wedge-shaped. When the vehicle is moving, the air can be efficiently introduced into the heat dissipation area inside the through hole 8 at a specific angle and speed under the guidance of the wedge shape. The guide ring 9 is made of engineering plastic. Engineering plastic has a low density, which allows the guide ring 9 to achieve its airflow guidance function without significantly increasing the overall weight of the wheel hub.

[0035] Working principle: During use, the multiple spokes 2 on the outside of the hub 1 drive the rim 11 and tire 12 to rotate. The trapezoidal spoiler grooves 3 inside the spokes 2 and the arc-shaped carbon fiber spoiler 4 on the outside work together. When the vehicle is moving and air flows through it, the spoiler grooves 3 accelerate the airflow by using the characteristics of a large opening and a narrow opening, and the spoiler 4 guides the direction of the airflow, optimizes the aerodynamic environment, reduces air resistance and energy loss, and enhances the stability and handling of the wheel during driving. At the same time, the positioning post 7 on the rear side of the hub 1 is quickly inserted into the pre-designed positioning hole or positioning groove during installation. Together with the fixing hole 5 and the center locking hole 6, it ensures accurate installation, reduces wheel imbalance, and further improves wheel stability.

[0036] When the vehicle is in motion, the wedge-shaped annular guide ring 9 on the front side of the hub 1 allows air to be introduced into the through hole 8 inside the hub 1 at a specific angle and speed. When the airflow passes through the through hole 8, the high-speed airflow comes into full contact with the heat dissipation fins 10. Under the effect of convection heat transfer, the heat is quickly carried away, achieving efficient heat dissipation and ensuring the thermal stability of the hub 1 during driving.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
