Description

Technical Field

[0001] This utility model belongs to the field of truck wheel technology, and in particular relates to a truck wheel. Background Technology

[0002] The air vents on existing truck and bus wheel hubs mostly use simple geometric shapes such as circles, squares, or rectangles. The chamfers on the edges of the air vents are small or even absent. When air flows through the air vents, vortices are easily formed, resulting in high air resistance, increased vehicle fuel consumption, and the sharp edges of the air vents generate significant wind noise, affecting driving comfort. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a truck wheel, including a hub body, characterized in that it further includes: The mounting hole is formed through the center of the hub body; The mounting hole has a plurality of connecting holes, which are evenly distributed around the circumference of the mounting hole. Shell-shaped air vents: Several evenly distributed shell-shaped air vents are opened through the circumferential edge area of ​​the wheel hub body; The shell-shaped air vents are chamfered to transition between the vents and the wheel hub body. The shell-shaped air vent has a shape that is narrow at both ends and wide in the middle.

[0004] Furthermore, it also includes: A transition surface is also provided on the side of the shell-shaped air hole facing the connecting hole. The transition surface extends smoothly from the inner edge to the outer edge of the shell-shaped air hole. The area of ​​the transition surface is at least 1 / 3 of the cross-sectional area of ​​the shell-shaped air vent.

[0005] Furthermore, the chamfer and the angle formed by the transition surface and the sidewall of the shell-shaped air hole are both obtuse angles.

[0006] Furthermore, the angle formed by the chamfer and the transition surface with the centerline of the shell-shaped air hole is 40°.

[0007] Furthermore, at least six shell-shaped air vents are provided.

[0008] Furthermore, the cross-sectional outline of the shell-shaped air vents is transitioned by circular arcs.

[0009] Furthermore, the chamfers, shell-shaped vents, and transition surfaces all have an anti-corrosion coating.

[0010] Furthermore, the chamfer, shell-shaped air vents, and transition surfaces are all free of protrusions and depressions.

[0011] The beneficial effects of this utility model are as follows: 1. It can guide air to flow smoothly along the shell-shaped air vents, reduce eddy currents to reduce air resistance, and eliminate sharp edges to reduce wind noise, thereby improving the aerodynamic performance of existing wheels and driving comfort.

[0012] 2. By setting a transition surface, airflow disturbance can be further reduced on the basis of Example 1, and air resistance and wind noise can be reduced; at the same time, the larger area of ​​the transition surface can further prevent rainwater and dust from accumulating inside the air hole, reducing the risk of corrosion.

[0013] 3. It can enhance the aerodynamic effect of chamfers and transition surfaces, further reducing wind noise and air resistance; at the same time, eliminating sharp angles can reduce the retention of corrosive media and extend the service life of the wheel hub.

[0014] 4. It can ensure that the chamfer and transition surface can give full play to their advantages without sacrificing the ventilation function of the air vents and the overall structural stability of the wheel hub, thus avoiding wheel hub performance loss due to improper angle design.

[0016] 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

[0017] This embodiment provides a truck wheel, including a hub body 1, and further comprising: Mounting hole 2 is formed through the center of the hub body 1; The connecting holes 3 are of several kinds, and the several connecting holes 3 are evenly distributed around the circumference of the mounting hole 2; Shell-shaped air holes 4: Several evenly distributed shell-shaped air holes 4 are opened through the circumferential edge area of ​​the hub body 1. Chamfer 5: The shell-shaped air hole 4 and the wheel hub body 1 are transitioned by chamfer 5; The shell-shaped air vent 4 has a shape that is narrow at both ends and wide in the middle.

[0018] In this technical solution, the mounting hole 2 and the connecting hole 3 are used to connect the wheel hub body 1 to the external axle, so that the axle can drive the wheel hub body 1 to rotate (the axle and the connection method are existing technologies and will not be described in detail here). Mounting hole 2 serves as the mating reference between wheel hub body 1 and axle, ensuring coaxiality during wheel hub assembly; while connecting holes 3 are evenly distributed around mounting hole 2, ensuring balanced force distribution when the wheel is fixed, avoiding localized stress concentration. like Figure 1-5As shown, the shell-shaped air vent 4 has a profile that is narrow at both ends and wide in the middle, which adapts to the airflow characteristics and reduces airflow impact; the chamfer 5 is used to eliminate the sharp edge at the junction of the air vent and the hub body 1, solving the problem of sharp edges caused by the lack of chamfer in the existing air vents, and preventing rainwater and dust from accumulating at the edge of the air vent.

[0019] Meanwhile, compared to simple-shaped air vents, the shell-shaped air vent 4 is more aesthetically pleasing; This structural design can initially guide air to flow smoothly along the shell-shaped air holes 4, reduce vortex generation to reduce air resistance, and eliminate sharp edges to reduce wind noise, thereby improving the aerodynamic performance and driving comfort of existing wheels. Example 2

[0020] This embodiment provides a truck wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0021] Furthermore, it also includes: A transition surface 6 is provided on the side of the shell-shaped air hole 4 facing the connecting hole 3. The transition surface 6 extends smoothly from the inner edge to the outer edge of the shell-shaped air hole 4. The area of ​​the transition surface 6 is at least 1 / 3 of the cross-sectional area of ​​the shell-shaped air hole 4.

[0022] In this technical solution, the transition surface 6 is set on the side of the shell-shaped air hole 4 facing the connecting hole 3, and its inner edge extends smoothly to the outer edge, thereby further optimizing the path of airflow through the air hole and avoiding airflow reversal inside the air hole. Meanwhile, the area of ​​transition surface 6 shall not be less than 1 / 3 of the cross-sectional area of ​​shell-shaped air hole 4 (the cross-sectional area of ​​shell-shaped air hole refers to the area specified in the appendix). Figure 5 The inner contour area of ​​the shell-shaped air vent allows the transition surface 6 to have a large area, thereby ensuring the transition guidance range and ensuring that most of the air flowing through the air vent can be smoothly guided.

[0023] Through this structural design, by setting the transition surface 6, airflow disturbance can be further reduced on the basis of embodiment 1, and air resistance and wind noise can be reduced; at the same time, the larger area of ​​the transition surface 6 can further prevent rainwater and dust from accumulating inside the air hole, reducing the risk of corrosion. Example 3

[0024] This embodiment provides a truck wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0025] Furthermore, the angles formed by the chamfer 5 and the transition surface 6 with the sidewall of the shell-shaped air hole 4 are all obtuse angles.

[0026] In this technical solution, the obtuse angle design can completely avoid the sharp angle formed between the chamfer 5, the transition surface 6 and the side wall of the air hole. If the angle formed is an acute angle or a right angle, it will easily create an airflow stagnation area and a pollutant accumulation point. The obtuse angle can make the airflow transition more smoothly along the connection, while reducing the space for dust and rainwater to adhere.

[0027] This structural design enhances the aerodynamic effect of the chamfer 5 and the transition surface 6, further reducing wind noise and air resistance. At the same time, eliminating sharp angles reduces the retention of corrosive media and extends the service life of the wheel hub. Example 4

[0028] This embodiment provides a truck wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0029] Furthermore, the angle formed by the chamfer 5 and the transition surface 6 with the center line of the shell-shaped air hole 4 is 40°.

[0030] In this technical solution, such as Figure 4 As shown, the angle formed by the chamfer 5 and the transition surface 6 with the center line of the shell-shaped air hole 4 is preferably 40°. In actual testing, if the angle is too large, it will easily lead to a reduction in the effective flow area of ​​the air hole, affecting the heat dissipation and ventilation effect; if the angle is too small, it will not be able to fully play the role of guiding airflow and eliminating sharp edges. A 40° angle can achieve a relatively balanced effect.

[0031] This structural design ensures that chamfer 5 and transition surface 6 can leverage their advantages without sacrificing the ventilation function of the air vents or the overall structural stability of the wheel hub, thus avoiding performance degradation of the wheel hub due to improper angle design. Example 5

[0032] This embodiment provides a truck wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0033] Furthermore, the shell-shaped air vent 4 is provided with at least 6 vents.

[0034] In this technical solution, the number of shell-shaped air holes 4 is preferably 6, and the 6 air holes are evenly and circumferentially distributed on the wheel hub body 1.

[0035] Too few air vents will result in an excessively large area of ​​each vent, affecting the structural strength of the wheel hub; too many air vents will result in an overly dense distribution of air vents, increasing the probability of airflow interference; six shell-shaped air vents evenly distributed can maintain the balance of force on the wheel hub while ensuring the total amount of airflow.

[0036] This structural design enables uniform airflow distribution at the wheel hub edge, reducing eddies caused by concentrated airflow and further lowering air resistance. At the same time, the balanced distribution of air vents ensures the overall structural strength of the wheel hub and avoids safety hazards caused by an inappropriate number of air vents. Example 6

[0037] This embodiment provides a truck wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0038] Furthermore, the cross-sectional outline of the shell-shaped air vent 4 is transitioned by a circular arc.

[0039] In this technical solution, such as Figure 5 As shown, the arc transition can eliminate all straight angles on the contour line of the shell-shaped air hole 4, so that when the airflow passes through the air hole, it is not easy to generate turbulence at the contour angle, thereby reducing wind noise and air resistance; the arc contour can guide the airflow to flow continuously along the surface of the air hole, which conforms to aerodynamic characteristics.

[0040] This structural design further reduces eddies and turbulence, lowering wind resistance and noise. At the same time, the rounded contour makes the air vent shape more closely resemble the natural biomimetic form of a seashell, enhancing the aesthetic appeal of the wheel hub. Example 7

[0041] This embodiment provides a truck wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0042] Furthermore, the surfaces of the chamfer 5, the shell-shaped air hole 4, and the transition surface 6 are all coated with an anti-corrosion coating.

[0043] This structural design significantly improves the corrosion resistance of areas prone to pollutant accumulation, such as chamfer 5, air vents, and transition surfaces 6, extending the overall service life of the wheel while preventing the corrosive effects of rainwater and dust on the wheel hub body 1. Example 8

[0044] This embodiment provides a truck wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0045] Furthermore, the surfaces of the chamfer 5, the shell-shaped air hole 4, and the transition surface 6 are all free of protrusions and depressions.

[0046] In this technical solution, the surfaces of the chamfer 5, the shell-shaped air hole 4, and the transition surface 6 can have low surface roughness, preferably Ra 1.6 μm or less. A smooth surface can ensure smooth airflow and prevent pollutants from adhering.

[0047] This structural design avoids surface defects from interfering with wheel hub performance, further reducing wind noise and wind resistance; at the same time, the smooth surface reduces the adhesion points of pollutants, improving the wheel hub's corrosion resistance and appearance.

[0048] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features described in this application specification can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
