Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, specifically to a wheel and a vehicle. Background Technology

[0002] In automobile manufacturing, the wheel rim, as a core component of the wheel, directly affects the vehicle's driving safety, comfort, and durability through its structural strength and vibration characteristics. Wheel rim modes refer to the vibration patterns of the wheel rim at specific frequencies. If the modal frequency is too low or the modal shape is unreasonable, it can cause resonance in the wheel rim during its formation, leading to noise, fatigue cracks, and even structural failure.

[0003] With the advancement of automotive lightweighting trends, the thickness of wheel rim materials has been reduced. In traditional wheel rim designs, due to uneven material distribution or insufficient structural design, the modal frequency of the wheel rim is often low. When the vehicle is traveling at high speed or under complex road conditions, the wheel rim is easily subjected to external excitation and generates severe vibration, affecting vehicle performance.

[0004] Currently, the modal frequency of a wheel rim is usually increased by increasing the thickness of the material used in its production or by changing its geometry. However, increasing the material thickness will significantly increase the weight of the wheel rim, and changing the geometry of the wheel rim places strict requirements on the production process, which will significantly increase the manufacturing cost. Utility Model Content

[0005] (I) This utility model provides a wheel and vehicle that alleviates the technical problem that increasing the modal frequency of the wheel rim will significantly increase the weight or manufacturing cost in the prior art.

[0009] The inner wall of the rim is provided with the reinforcing member, which is located on the side of the wheel spoke facing the center of gravity of the frame. The reinforcing member is arranged along the circumference of the rim and can improve the strength of the rim.

[0010] Furthermore, at least one reinforcing member is provided, and the reinforcing member is in the form of a closed ring.

[0013] Furthermore, the ends of the first connecting portion and the second connecting portion opposite to the support section are welded to the wheel rim.

[0014] Furthermore, the sidewall of the first or second connecting portion is welded to the wheel rim.

[0038] Example 1

[0039] like Figures 1 to 8 As shown, this utility model provides a wheel, which is mounted on an axle and connected to a frame. It includes a rim 100, spokes 200, and a reinforcing member 300. The rim 100 and spokes 200 are connected. The inner wall of the rim 100 is provided with a reinforcing member 300, which is located on the side of the spokes 200 facing the center of gravity of the frame. The reinforcing member 300 is arranged along the circumference of the rim 100 and can improve the strength of the rim 100.

[0040] In this embodiment, the wheel includes a rim 100, spokes 200, and a reinforcing member 300. The rim 100 and spokes 200 are connected to form the wheel. A reinforcing member 300 is provided on the inner wall of the rim 100. The reinforcing member 300 is located on the inner wall of the rim 100 corresponding to the side of the spokes 200 facing the center of gravity of the frame. The reinforcing member 300 is arranged along the circumference of the rim 100. The reinforcing member 300 can improve the strength of the rim 100. That is, the reinforcing member 300 effectively increases the local stiffness and overall structural strength of the rim 100, thereby significantly increasing the modal frequency of the rim 100, avoiding the occurrence of resonance, and reducing the vibration of the rim 100. This helps to reduce noise and vibration during vehicle operation, and can improve driving comfort and safety. The reinforcing component 300 only provides localized reinforcement to the areas of the rim 100 that require reinforcement, thus avoiding an overall increase in the weight of the rim 100. At the same time, the processing and installation of the reinforcing component 300 are simple, requiring no modification to the structure of the rim 100 and spokes 200, thereby reducing production costs and process complexity.

[0041] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, there is at least one reinforcing member 300, and the reinforcing member 300 is in the form of a closed ring.

[0042] In this embodiment, the reinforcing member 300 is in the shape of a closed ring. The reinforcing member 300, which is arranged in a closed ring shape, can be easily arranged along the inside of the rim 100. At the same time, it can also ensure that the parts of the rim 100 that need to be reinforced can be uniformly reinforced locally along the circumference of the rim 100, so that the local stiffness and overall structural strength of the rim 100 are effectively increased.

[0043] Correspondingly, the production and installation processes of the closed-ring reinforcement 300 are relatively simple, effectively reducing production costs and process complexity.

[0044] Of course, the reinforcing member 300 can also be composed of several small segments and arranged circumferentially along the inner wall of the rim 100. Whether it is evenly spaced or closely connected, it does not deviate from the design concept of this utility model and should fall within the protection scope of this utility model.

[0045] like Figure 7 and Figure 8 As shown, the number of reinforcing members 300 can be more than one; there can be two or more spaced along the width of the rim 100. The number of reinforcing members 300 can be set according to actual usage requirements.

[0046] According to one embodiment provided by this utility model, such as Figure 1 and Figure 3 As shown, the rim 100 has an inner rim 101, and a reinforcing member 300 is disposed on the inner wall of the inner rim 101.

[0047] In this embodiment, the rim 100 has an inner rim 101, and correspondingly, the rim 100 also has an outer rim opposite to the inner rim 101. The spokes 200 are installed on the side close to the outer rim. Therefore, when the reinforcing member 300 is located on the inner wall corresponding to the inner rim 101, the modal frequency enhancement effect of the rim 100 is optimal, and the resonance phenomenon can be fully avoided.

[0048] According to one embodiment provided by this utility model, such as Figure 3 As shown, the reinforcing member 300 includes a first connecting part 301, a second connecting part 302 and a support section 303. The first connecting part 301 and the second connecting part 302 are connected by the support section 303. The first connecting part 301 and / or the second connecting part 302 are fixedly connected to the rim 100.

[0049] In this embodiment, the reinforcing member 300 includes a first connecting portion 301, a second connecting portion 302, and a support section 303. Preferably, the first connecting portion 301, the second connecting portion 302, and the support section 303 are integrally formed, that is, the first connecting portion 301 and the second connecting portion 302 are connected by the support section 303, and the reinforcing member 300 is fixedly connected to the rim 100 through the first connecting portion 301 and / or the second connecting portion 302.

[0050] According to one embodiment provided by this utility model, such as Figure 1 , Figure 3 and Figure 5 As shown, the ends of the first connecting part 301 and the second connecting part 302 that are away from the support section 303 are welded to the rim 100.

[0051] In this embodiment, preferably, the reinforcing member 300 is welded to the inner wall of the rim 100 by laser welding. That is, the first connecting part 301 and the second connecting part 302 are fixed by welding the ends away from the support section 303 to the rim 100, so as to enhance the local stiffness and overall structural strength of the corresponding parts of the rim 100 that need to be reinforced by the reinforcing member 300.

[0052] According to one embodiment provided by this utility model, such as Figure 6 and Figure 8 As shown, the sidewall of the first connecting part 301 or the second connecting part 302 is welded to the rim 100.

[0053] In this embodiment, the wheel rim 100 can also be fixed by welding the sidewall of the first connecting part 301 or the second connecting part 302 to the wheel rim 100. That is to say, after welding and fixing, the opening formed by the first connecting part 301, the second connecting part 302 and the support section 303 can face either side, which is not limited here. Therefore, by fixing the wheel rim 100 to the sidewall of either the first connecting part 301 or the second connecting part 302, the effect of strengthening the local stiffness and overall structural strength of the corresponding part of the wheel rim 100 that needs to be strengthened by the reinforcing member 300 can be achieved.

[0054] Of course, the methods of fixing the reinforcing member 300 to the rim 100 include, but are not limited to, using laser welding. Other methods can also be used for fixing, which are existing technologies and will not be elaborated further.

[0055] like Figure 4 and Figure 7As shown, the ends of the first connecting part and the second connecting part of the reinforcing member provided in this embodiment that are away from the support section can also be integral. That is to say, the reinforcing member can also be made of integral hollow tube and fixed to the rim by laser welding. Its purpose has not deviated from the design concept of this utility model and should be within the protection scope of this utility model.

[0056] According to one embodiment provided by this utility model, such as Figure 1 and Figure 3 As shown, the rim 100, the first connecting part 301, the second connecting part 302, and the support section 303 enclose a cavity 400.

[0057] In this embodiment, since the first connecting part 301, the second connecting part 302 and the support section 303 are integrally formed, the first connecting part 301, the second connecting part 302 and the support section 303 can form a cavity 400 together with the inner wall of the rim 100. By setting the cavity 400, the production process required for welding and fixing the reinforcing member 300 to the inner wall of the rim 100 can be simplified. At the same time, setting the cavity 400 can also reduce the weight, and the weight of the rim 100 will not increase significantly due to the addition of the reinforcing member 300.

[0058] According to one embodiment provided by this utility model, such as Figure 5 As shown, the cross-section of the reinforcing member 300 is C-shaped, elliptical, convex, concave, or ingot-shaped.

[0059] In this embodiment, the overall cross-section of the reinforcing member 300 can be C-shaped, elliptical, convex, concave, or ingot-shaped. Reinforcing members 300 with different cross-sectional shapes can all improve the modal frequency of the rim 100 to a certain extent.

[0060] Of course, the cross-sectional shape of the reinforcing member 300 can also be trapezoidal, polygonal or other shapes, which do not deviate from the design concept of this utility model and should fall within the protection scope of this utility model.

[0061] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the spoke 200 includes a mounting area 201, which is located at the center of the spoke 200, and the wheel is mounted to the axle through the mounting area 201.

[0062] In this embodiment, the spoke 200 includes a mounting area 201, which is located at the center of the spoke 200. The mounting area 201 includes multiple screw hole seats, and screw holes are provided on the screw hole seats. The screw holes facilitate the direct connection between the wheel and the axle. The wheel can be fixed to the axle by passing a bolt through the screw hole. In other words, the wheel is mounted on the axle through the mounting area 201.

[0063] Of course, the spokes 200 can also be configured to have air vents 202 depending on actual usage needs. When the spokes 200 has multiple air vents 202, the multiple air vents 202 are evenly distributed along the circumference of the spokes 200. The air vents 202 guide airflow to directly cool the vehicle's brake discs and calipers, reduce the risk of heat fade, and remove excess material to effectively reduce the weight of the wheel. At the same time, the air vents 202 can also effectively drain water accumulated inside the wheel.

[0064] Example 2

[0065] This utility model also provides a vehicle, including a wheel, which is the wheel described above.

[0066] In this embodiment, the vehicle uses the aforementioned wheel. The reinforcing member 300 enhances the strength of the rim 100, effectively increasing the local stiffness and overall structural strength of the rim 100. This significantly improves the modal frequency of the rim 100, preventing resonance and reducing rim 100 vibration, thus reducing vehicle noise and vibration during driving and improving driving comfort and safety. Furthermore, the wheel equipped with the reinforcing member 300 only locally strengthens the rim 100 where reinforcement is needed, avoiding an overall increase in rim 100 weight. This prevents a significant increase in vehicle weight. The reinforcing member 300 is simple to manufacture and install, requiring no modification to the rim 100 and spoke 200 structures, reducing wheel production costs and process complexity, and further lowering vehicle manufacturing costs.

[0067] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
