Description

Technical Field

[0001] The utility model relates to the technical field of vehicle engineering, and particularly relates to a low wind resistance structure device for the outer cover of a wheel housing. Background Art

[0002] With the continuous development of the automotive industry, reducing vehicle energy consumption and improving driving performance have become important research directions. Wind resistance is one of the important factors affecting vehicle energy consumption and driving performance. Especially when driving at high speeds, wind resistance has a significant impact on the power demand and fuel consumption of the vehicle.

[0003] As a component of the vehicle in contact with the ground, the wheel will generate a large amount of wind resistance during driving. Traditional wheel designs usually do not consider the impact of wind resistance. The irregular shapes of the wheel hub and tire will cause air flow disorders and increase wind resistance. In addition, the wheel generates heat during driving. If the heat cannot be dissipated in time, it will affect the performance and service life of the tire and braking system.

[0004] To solve these problems, a new type of low wind resistance structure device for the outer cover of a wheel housing is needed. This device can reduce the wind resistance of the wheel, improve the fuel economy and driving performance of the vehicle, and at the same time ensure the heat dissipation effect of the wheel and extend the service life of the tire and braking system. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a low wind resistance structure device for the outer cover of a wheel housing, which can effectively solve the problems in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A low wind resistance structure device for the outer cover of a wheel housing includes a wheel connecting body and bolts. The front end and the rear end of the wheel connecting body are both fixedly connected with outer cover bodies. A plurality of threaded holes are opened on the inner wall surfaces of the two outer cover bodies. A plurality of bolts are provided. The plurality of threaded holes are clamped with two wheel hubs through the plurality of bolts. A plurality of heat dissipation holes are opened on the inner surfaces of the two outer cover bodies, and a retaining net is arranged in each of the plurality of heat dissipation holes.

[0008] Preferably, the inner sides of the two outer cover bodies are both in a sharp shape, and the outer sides gradually narrow.

[0009] By adopting the above technical solution: The design with a sharp inner side and a narrowing outer side can reduce the air impact area, reduce wind resistance, and improve the fuel economy and driving performance of the vehicle.

[0010] Preferably, the gap between the outer cover body and the wheel hub does not exceed five millimeters.

[0011] By adopting the above technical solutions: a gap not exceeding five millimeters can prevent air from entering to form turbulence, reduce wind resistance, and at the same time prevent foreign objects from entering, ensuring the stability of the wheel operation.

[0012] Preferably, the edge of the outer cover body is closely attached to the tire.

[0013] By adopting the above technical solutions: the edge of the outer cover body is closely attached to the tire, which can avoid air leakage, reduce wind resistance, and at the same time prevent foreign objects from entering through the gap and damaging the wheel.

[0014] Preferably, the outer surface of the outer cover body is polished.

[0015] By adopting the above technical solutions: the outer surface of the outer cover body is polished, reducing air friction resistance, decreasing wind resistance, making the vehicle run more smoothly, and improving fuel economy.

[0016] Preferably, the shapes of several of the heat dissipation holes are inclined designs, and several of the heat dissipation holes are distributed in a central annular array of two outer cover bodies.

[0017] By adopting the above technical solutions: the heat dissipation holes are inclined and distributed in an annular array, generating a downward pressure while effectively dissipating heat, increasing vehicle stability, and reducing wind resistance.

[0018] Preferably, the retaining net is made of corrosion-resistant and high-strength materials.

[0019] By adopting the above technical solutions: the retaining net of this device is made of stainless steel wire mesh material, which can effectively block foreign objects from entering the heat dissipation holes and at the same time does not hinder the air circulation.

[0020] Compared with the prior art, the present utility model has the following beneficial effects:

[0021] 1. In the present utility model, the inner side surface of the outer cover body is in a sharp shape and the outer side surface gradually narrows, forming a streamlined structure, which can effectively guide the smooth flow of air, reduce the generation of airflow separation and turbulence, and thus significantly reduce the wind resistance of the wheel. Low wind resistance means that the air resistance that the vehicle needs to overcome during driving is reduced, and the power output of the engine can be more effectively converted into the forward power of the vehicle, thereby reducing fuel consumption and improving fuel economy. For example, in actual tests, the fuel consumption of the vehicle equipped with this device can be reduced by [X]% compared with traditional wheels under the same driving conditions, saving fuel costs for users and at the same time reducing environmental pollution.

[0022] 2. In the present utility model, a number of heat dissipation holes with an inclined design and arranged in an annular array are provided on the outer cover body of the device, which can effectively dissipate the heat generated by the wheel. The corrosion-resistant and high-strength retaining nets arranged in the heat dissipation holes can prevent foreign objects from entering the wheel interior and will not impede the air circulation, ensuring the heat dissipation effect. This good heat dissipation performance enables the tire and the braking system to work at an appropriate temperature, extending their service life. For example, after a long-term use comparison, the wear degree of the vehicle tires equipped with this device is significantly lower than that of the vehicles with traditional wheels, and the performance of the braking system is also more stable and reliable, reducing the maintenance and replacement costs for users.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0030] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "provided with", "connection", etc. shall be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0032] A low wind resistance structure device for the outer cover of a wheel housing, comprising a wheel connection body 1 and bolts 5, characterized in that: both the front end and the rear end of the wheel connection body 1 are fixedly connected with outer cover bodies 2, and a plurality of threaded holes 3 are opened on the inner wall surfaces of the two outer cover bodies 2. A plurality of bolts 5 are provided, and the two hubs 4 are clamped by the plurality of threaded holes 3 through the plurality of bolts 5. A plurality of heat dissipation holes 6 are opened on the inner surfaces of the two outer cover bodies 2, and a retaining net 7 is provided in each of the plurality of heat dissipation holes 6.

[0033] Through the above solution: First, the wheel connection body 1, as a connecting component, fixes the two outer cover bodies 2 at the corresponding positions of the wheel. The outer cover body 2 cooperates with a plurality of bolts 5 through a plurality of threaded holes 3 on the inner wall surface to clamp the two hubs 4 inside the outer cover body 2. Such a connection method ensures the firm combination of the outer cover body 2 and the hub 4, and will not loosen or fall off during the driving of the vehicle. When heat is generated during the driving of the wheel, the plurality of heat dissipation holes 6 opened on the inner surface of the outer cover body 2 start to play a role, and the heat can be dissipated through the heat dissipation holes 6 to ensure the normal working temperature of the wheel. At the same time, the retaining net 7 can effectively prevent foreign objects from entering the wheel interior, and at the same time will not hinder the air circulation, ensuring the continuous and stable heat dissipation effect.

[0034] In this embodiment, the inner sides of the two outer cover bodies 2 are both in a sharp shape, and the outer sides gradually narrow; the gap between the outer cover body 2 and the hub 4 does not exceed five millimeters; the edge of the outer cover body 2 is closely attached to the tire; the outer surface of the outer cover body 2 is polished; the shapes of the plurality of heat dissipation holes 6 are inclined designs, and the plurality of heat dissipation holes 6 are distributed in a central annular array of the two outer cover bodies 2; the retaining net 7 is made of a corrosion-resistant and high-strength material.

[0035] Through the above solution: The inner sides of the two outer cover bodies 2 are in a sharp shape. When the vehicle is running, this design enables air to flow more smoothly from front to back, reducing the impact area of air at the front end and lowering the wind resistance. The gradually narrowing outer sides further guide the air to flow quickly past the outer cover bodies, reducing the generation of airflow separation and turbulence; the gap between the outer cover body 2 and the wheel hub 4 does not exceed five millimeters, preventing excessive air from entering this gap to form turbulence, thereby maintaining the stability of the airflow and reducing the wind resistance. At the same time, the edge of the outer cover body 2 fits tightly with the tire, preventing air from leaking through the gap between the tire and the outer cover body, ensuring that the airflow around the entire wheel is more regular and further reducing the wind resistance; the outer surface of the outer cover body 2 is polished to make the surface smoother, reducing the frictional resistance between the air and the surface of the outer cover body and reducing the energy loss and wind resistance caused by friction; several heat dissipation holes 6 are distributed in a central annular array on the two outer cover bodies 2. On the one hand, it ensures the uniformity of heat dissipation in all directions of the wheel. On the other hand, the inclined design of the heat dissipation holes causes the air to generate a downward pressure when flowing out of the heat dissipation holes. This pressure acts on the wheel, increasing the adhesion between the vehicle and the ground and improving the driving stability of the vehicle. At the same time, while the heat dissipation holes achieve the heat dissipation function, they do not overly increase the wind resistance due to their existence, because the inclined design optimizes the angle between the direction of air outflow and the direction of vehicle travel, reducing the interference to the airflow; the retaining net 7 is made of corrosion-resistant and high-strength materials and is installed in the heat dissipation holes 6. It can effectively prevent foreign objects from entering the wheel interior, prevent foreign objects from damaging the wheel, braking system, etc., and at the same time ensure the normal ventilation and heat dissipation function of the heat dissipation holes, ensuring that the wheel works in a safe environment. And due to its corrosion-resistant characteristics, it can maintain good performance for a long time, reducing the maintenance cost.

[0036] It should be noted that the present utility model is a low-wind-resistance structural device for the outer cover of a wheel housing. During use, first, check whether the wheel connecting body 1 is intact to ensure that it can be normally connected to the outer cover body 2. Place the two outer cover bodies 2 at the front end and the rear end of the wheel respectively, with the sharp-shaped inner side of the outer cover body 2 facing the vehicle travel direction and the gradually narrowing outer side facing the rear. Adjust the position of the outer cover body 2 to align it with the wheel hub 4, ensuring that the gap between the outer cover body 2 and the wheel hub 4 does not exceed five millimeters. At the same time, the edge of the outer cover body 2 fits tightly with the tire. Use several bolts 5 to snap-connect and fix the outer cover body 2 to the wheel hub 4 through the threaded holes 3 on the inner wall surface to ensure a firm connection. Check whether the several heat dissipation holes 6 on the outer cover body 2 are unobstructed and whether the retaining net 7 is firmly installed and undamaged. The inclined design of the heat dissipation holes 6 should ensure that the air can generate a downward pressure when flowing out to increase the vehicle stability. The retaining net 7 is made of corrosion-resistant and high-strength materials to prevent foreign objects from entering the wheel interior. Conduct an overall inspection of the installed low-wind-resistance structural device to ensure that each component is correctly and firmly installed, the gap meets the requirements, and the heat dissipation hole function is normal.
