Description

Technical Field

[0001] The utility model relates to the technical field of vehicle manufacturing, in particular to a rim of a wheel, a wheel with the rim, and a vehicle with the wheel. Background Art

[0002] The wheel consists of a tire, a hub, spokes and a rim. The tire is made of rubber, and the hub, spokes and rim are made of metal (common materials are steel, aluminum alloy or carbon fiber, etc.). During a collision, the above metal structure accepts the huge impact force exerted by the barrier and transmits it to the body and door sill, keeping the force transmission path unobstructed during the collision and reducing the impact damage to the passenger compartment.

[0003] With the widespread use of aluminum alloy subframes in high-end models, due to the poor stability of aluminum alloy's mechanical properties, aluminum alloy swing arms and subframes often fail prematurely in 25% offset collisions. The wheels quickly tilt (fly out) during the collision, making it possible for the wheels to not directly contact the door sill, resulting in a poor force transmission path and poor crushing energy absorption effect, causing impact damage to the passenger compartment. There is room for improvement. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0035] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0036] Unless otherwise specified, the front-to-back direction in this application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0037] Reference below Figure 1-Figure 3 The wheel rim 100 according to an embodiment of the present invention is described. By providing a reinforcement portion 31 on the rim, with a radial thickness greater than that of other rim portions 32, the rim's structural strength is enhanced while slightly increasing its weight. This significantly improves the vehicle's resistance to frontal collisions, enhances overall vehicle strength, and strengthens the underbody force transmission path, ensuring a smooth wheel-to-sill force transmission path during a frontal collision, thereby enhancing the vehicle's collision safety and reliability. Furthermore, by strengthening portions of the rim's structure, the overall structure is reduced in thickness, meeting lightweight design requirements. Furthermore, a lightweight rim can reduce overall vehicle weight, thereby improving fuel efficiency and handling performance.

[0038] It should be noted that the wheel is composed of a tire, a hub, spokes and a rim, wherein the tire material is rubber, and the hub, spokes and rim are made of metal (common materials are steel, aluminum alloy or carbon fiber, etc.); therefore, the weight of the wheel is mainly concentrated on the metal structures such as the hub, spokes and rim, wherein the tire is installed on the rim, and the hub and spokes have a large material thickness, mass and strength, which play a supporting and strengthening role on the rim to achieve the installation of the wheel.

[0039] like Figure 1-Figure 3 As shown, a wheel rim 100 according to an embodiment of the present invention comprises a rim inner ring portion 1, a rim outer ring portion 2 and a rim main body portion 3. The rim inner ring portion 1 and the rim outer ring portion 2 are respectively connected to the axial sides of the rim main body portion 3 and are both constructed to be bent outward relative to the rim main body portion 3. The rim main body portion 3 comprises a reinforcement portion 31. In the radial direction along the rim main body portion 3, the thickness of the reinforcement portion 31 is greater than the thickness of other portions 32 of the rim main body portion 3 outside the reinforcement portion 31.

[0040] Specifically, the rim includes a rim inner ring portion 1, a rim main body portion 3 and a rim outer ring portion 2 connected in sequence. The rim structure is a circular structure, and the rim inner ring portion 1, the rim main body portion 3 and the rim outer ring portion 2 are respectively circular structures. In actual design, the rim inner ring portion 1 and the rim outer ring portion 2 can be set to have the same structure. The rim main body portion 3 has a smooth surface, and the axial side edges of the rim main body portion 3 are bent and extended along the radial direction of the rim main body portion 3 away from the center of the rim main body portion 3 to form the rim inner ring portion 1 and the rim outer ring portion 2. Among them, the design of the rim inner ring portion 1 and the rim outer ring portion 2 helps to fix the tire, ensure that the tire will not be displaced during high-speed rotation, and improve driving safety. The bending angle can be a right angle, an obtuse angle, etc. This setting can improve the rigidity and stability of the rim, so that the rim can better support the tire and disperse various loads transmitted by the tire, such as vehicle weight, lateral force, driving force and braking force.

[0041] The inner rim portion 1 and the outer rim portion 2 are bent outward relative to the main rim portion 3 to increase the contact area between the rim and the air, thereby improving heat dissipation efficiency. The bent connection guides airflow, reduces eddy currents at the wheel, and reduces air resistance. The appearance is smooth and flat, creating a good visual effect.

[0042] The rim body 3 is provided with a reinforcement portion 31 to enhance the structural strength of the rim body 3. In actual design, the reinforcement portion 31 and the rim body 3 can be integrally formed to enhance the connection strength between the reinforcement portion 31 and the rim body 3. The reinforcement portion 31 is thicker to enhance its structural strength, and the thickness of the reinforcement portion 31 is greater than that of the other portions 32 of the rim body 3. Thus, the reinforcement portion 31 enhances the overall structural strength and load-bearing capacity of the rim, thereby reducing the risk of deformation or damage to the rim when subjected to external forces.

[0043] Therefore, in the wheel structure, due to the larger rim area, there is a high probability of direct contact with the door sill during a collision, enabling direct force transmission, crushing and energy absorption. The larger contact area and more stable contact enhance the rim's structural strength while slightly increasing the rim's weight. This significantly improves the vehicle's frontal collision resistance, enhances overall vehicle strength, and strengthens the underbody force transmission path, ensuring a smooth wheel-to-door force transmission path during a frontal collision, thus increasing the vehicle's collision safety performance and reliability. Furthermore, the rim can disperse and withstand more stress, extending its service life, reducing replacement frequency and maintenance costs, and reducing the likelihood of rim cracking due to fatigue or impact, thereby reducing the risk of tire deflation and improving driving safety.

[0044] Furthermore, by providing a reinforcement portion 31 on the rim main body 3, the strength of the rim main body 3 can be locally reinforced to ensure the overall strength and stability of the rim, without reinforcing the overall structure of the rim. The overall structure will not be thick, and while meeting the strength requirements, it can meet the lightweight setting requirements and reduce the setting cost. The lightweight rim can reduce the weight of the entire vehicle, thereby improving fuel efficiency and handling performance.

[0045] In some embodiments, the reinforcement portion 31 is constructed as a reinforcement rib 311, and the reinforcement rib 311 is extended along the circumference of the rim main body 3. In this way, the circumference of the rim main body 3 can be reinforced by the reinforcement rib 311 to improve the structural strength of the rim main body 3, thereby improving the structural strength of the rim as a whole.

[0046] Specifically, if Figure 1-Figure 3 As shown, the rim main body 3 is constructed as a circular structure, and the reinforcing rib 311 extends along the circumference of the rim main body 3, wherein the reinforcing rib 311 can be constructed as a circular ring, and the reinforcing rib 311 can be integrally formed with the rim main body 3 to more effectively enhance the connection strength between the reinforcing rib 311 and the rim main body 3.

[0047] Therefore, by setting reinforcing ribs 311 circumferentially on the rim main body 3, the local structure of the rim main body 3 can be strengthened. The rim main body 3 is used to support and connect the tire, thereby improving the overall structural strength of the wheel. The setting method is simple, the structure is simple, and the setting cost is low.

[0048] In some embodiments, there are at least two reinforcing ribs 311 , and the at least two reinforcing ribs 311 are spaced apart along the axial direction of the rim body 3 .

[0049] Specifically, at least two reinforcing ribs 311 are distributed along the axial direction of the rim main body 3 at intervals, and reinforcement can be achieved at at least two locations in the axial direction of the rim main body 3. At least two reinforcing ribs 311 extend along the circumference of the rim main body 3 respectively, and reinforcement can be performed at multiple circumferential positions of the rim main body 3, thereby greatly improving the structural strength of the rim main body 3.

[0050] Among them, the reinforcing ribs 311 can be provided with two, three, four, five, etc. In this embodiment, as shown in FIG. Figure 3 As shown, there are three reinforcing ribs 311, which are distributed axially at intervals on the rim body 3, and the distance between two adjacent reinforcing ribs 311 is the same. In this way, the axial reinforcement structure of the rim body 3 can be made more uniform, thereby improving the structure of the rim body 3. The structural stability is improved, and the impact force can be dispersed and absorbed more stably, thereby improving the collision performance of the wheel in a collision.

[0051] It should also be noted that the structures of the rim inner ring portion 1 and the rim outer ring portion 2 are relatively complex, and the rim main body portion 3 includes a flat area. The reinforcing ribs 311 need to be evenly arranged in the flat area near the center line of the rim main body portion 3, away from the rim inner ring portion 1 and the rim outer ring portion 2, so that the processing of the rim is simpler and more convenient, and the processing cost is reduced.

[0052] In some embodiments, in the axial direction of the rim main body 3, as shown in FIG. Figure 2 As shown, the distance between two adjacent reinforcing ribs 311 is L1, and satisfies: 5mm≤L1≤100mm.

[0053] Specifically, the spacing L1 between two adjacent reinforcing ribs 311 can be set to 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, etc. By setting the above multiple values, a certain spacing can be set between two adjacent reinforcing ribs 311, so that the two adjacent reinforcing ribs 311 do not interfere with each other, and the structure can be effectively reinforced at different axial positions of the rim body 3. The axial dimension of the rim body 3 is matched according to the requirements of different tires and vehicles. That is, in the axial direction of the rim body 3, the structural strength of the rim body 3 can be enhanced by using different numbers of reinforcing ribs 311. The number of reinforcing ribs 311 and different spacings are selected according to the overall axial dimension to more effectively improve the structural strength of the rim body 3.

[0054] In some embodiments, in the axial direction of the rim main body 3, as shown in FIG. Figure 2 As shown, the width of the reinforcing rib 311 is L2, and satisfies: 5mm≤L2≤50mm.

[0055] Specifically, the width L2 of the reinforcement rib 311 can be: 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, etc. By setting the above multiple values, the reinforcement rib 311 can maintain a certain axial width to improve the self-strength of the reinforcement rib 311, and after the reinforcement rib 311 is embedded in the rim main body 3, the structural strength of the rim main body 3 can be improved. When the vehicle is hit by a collision, the impact force can be effectively dispersed and absorbed by the reinforcement rib 311, thereby improving the impact resistance of the rim and avoiding premature deformation of the rim structure, thereby making the force transmission path between the rim and the door sill smooth and stable, thereby improving the collision performance of the rim.

[0056] The width of the reinforcing rib 311 is not limited to the above, and can be selectively set according to the axial dimension of the rim body 3 .

[0057] In other embodiments, the number of reinforcing ribs 311 is A, and satisfies: 1≤A≤15. The number of reinforcing ribs 311 can be one, two, three, four, five, six, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, etc. By setting these values, the plurality of reinforcing ribs 311 are spaced apart and distributed along the axial direction of the rim body 3, and the dimensions of each reinforcing rib 311 can be the same. The plurality of reinforcing ribs 311 can improve the structural strength of the rim body 3. Furthermore, the number of reinforcing ribs 311 is not limited to the number described above and can be selectively set according to the actual rim specifications, with various configuration methods.

[0058] Furthermore, when only one reinforcing rib 311 is provided, the one reinforcing rib 311 is located at the center of the rim body 3 to more evenly improve the structural strength of the rim body 3 .

[0059] In some embodiments, in the radial direction along the rim main body 3, as shown in FIG. Figure 2 As shown, the thickness of the reinforcing rib 311 is L3, the thickness of the other portion 32 is L4, and the following conditions are satisfied: L3≤30mm, and / or the following conditions are satisfied: L3≤10L4.

[0060] Specifically, in the radial direction of the rim body 3, the thickness of the reinforcing rib 311 is different from the thickness of the other parts 32, such as Figure 2 and Figure 3 As shown, the radial thickness L3 of the reinforcing rib 311 can be: 20mm, 22mm, 24mm, 25mm, 26mm, 28mm, 30mm. By setting the above multiple values, the reinforcing rib 311 can maintain a certain radial thickness and achieve a certain reinforcement effect.

[0061] Alternatively, the radial thickness L3 of the reinforcing rib 311 can be set to within ten times the thickness L4 of the other parts 32, that is, the radial thickness of the reinforcing rib 311 can be 10L4, 9L4, 8L4, 7L4, etc. In this way, the radial thickness of the reinforcing rib 311 can be greater than the radial thickness of the other parts 32, and the local improvement of the rim can be achieved only by adjusting the size of the reinforcing rib 311, so as to effectively strengthen the structural strength of the rim main body 3.

[0062] Among them, in the actual design, in the radial direction of the rim main body 3, the reinforcing rib 311 can be kept flush with the outer side surface of the other parts 32 of the rim main body 3, and the radial inner side surface of the reinforcing rib 311 protrudes from the radial inner side surface of the other parts 32 of the rim main body 3 toward the center of the rim main body 3. In this way, the reinforcing rib 311 can not only enhance the structural strength of the rim main body 3, but also the radial thickness of the reinforcing rib 311 will not affect the normal safety and use of the wheel, and it is more convenient and reliable to use.

[0063] In some embodiments, the cross-section of the reinforcing rib 311 is configured as a rectangular surface, a circular surface, a semicircular surface, a triangular surface, or a fan-shaped surface.

[0064] Specifically, in actual design, the cross-section of the reinforcing rib 311 can be constructed as a rectangular surface, and the rectangular cross-section includes two shapes: square corners and rounded corners. The cross-sectional size of the reinforcing rib 311 with a rectangular surface is large, which can make the reinforcing rib 311 and the other parts 32 of the rim main body 3 completely connected, thereby improving the tightness of the connection between the two, so as to improve the overall structural strength. The cross-section of the reinforcing rib 311 can also be constructed as a circular surface, a semicircular surface, a triangular surface and a fan-shaped surface, etc., which can strengthen the overall structure of the rim main body 3 to a certain extent. The setting method is diverse and can be flexibly selected.

[0065] Among them, it should be noted that by adding reinforcing ribs 311 locally to the rim main body 3, the material utilization efficiency is extremely high. Through simulation and theoretical calculation, it can be seen that for every 45% increase in the rim mass (that is, the mass of the reinforcing rib 311), the rim crushing peak force can be increased by 100% and the crushing energy absorption can be increased by 126%, which can ensure the smoothness of the wheel-door force transmission path, ensure that the wheel fully crushes and absorbs energy, reduce the collision intrusion and deformation degree of the passenger compartment, protect the safety of the occupants, and increase the safety performance of the entire vehicle; in addition, it should be pointed out that the cross-section of the reinforcing rib 311 in the existing simulation calculation is in the form of a rectangular surface. If a circular or semicircular cross-section is used, the stress concentration in the area near the reinforcing rib 311 during the collision extrusion process will be effectively reduced, which can further increase the mechanical properties and crushing energy absorption of the wheel.

[0066] In some embodiments, a middle region of the rim body portion 3 in the axial direction of the rim body portion 3 is configured as the reinforced portion 31 .

[0067] Specifically, if Figure 4 and Figure 5 As shown, the central region of the rim body 3 is constructed as a reinforcement portion 31, and reinforcement ribs 311 extend axially from the central region at both ends. This allows the reinforcement portion 31 to occupy a larger area of ​​the central region of the rim body 3, thereby increasing the structural strength of the reinforcement portion 31. This arrangement can also improve the structural strength of the central region of the rim body 3, significantly enhancing the structural strength of the rim body 3 and thereby enhancing the overall structural strength of the rim. Furthermore, this arrangement simplifies the processing and manufacturing of the rim body 3 and reinforcement portion 31. Furthermore, when the reinforcement portion 31 comprises multiple reinforcement ribs 311, the multiple reinforcement ribs 311 are also arranged to be evenly spaced apart axially from the central region of the rim body 3 toward both ends, i.e., they can be symmetrically distributed along the axial direction, resulting in a uniform structural distribution and more uniform structural strength.

[0068] Among them, it should be noted that in actual processing, when forging or spinning processes are used to manufacture metal structural parts such as hubs, rims, and spokes, due to the limitations of the process level, the shape is generally relatively simple, and the surface of the hub is mostly simple and rough lines. Therefore, it is too difficult to process fine reinforcement ribs 311 on the surface of the rim as required. At this time, a reinforcement rib 311 with a larger axial width can be processed, which is simpler and more convenient to process.

[0069] Low-pressure casting technology can also conveniently and efficiently produce various cross-sectional shapes (circular, semicircular, triangular, fan-shaped, etc.) and sizes (the height of the rib 311 should be less than 30 mm or within 10 times the average rim thickness) that meet design requirements. This makes it particularly suitable for the manufacture of high-strength aluminum alloy rims (spokes, hubs). It should be noted that low-pressure casting utilizes low pressure to compress the mold against the liquid alloy. The resulting wheels have high metal density, high strength, fewer defects, more complex shapes, and a higher safety factor. Currently, this is the primary method for aluminum alloy wheel manufacturing, with a relatively high yield rate and a high degree of automation.

[0070] In some embodiments, in the axial direction of the rim main body 3, as shown in FIG. Figure 4 and Figure 5 As shown, the width of the reinforcement portion 31 is greater than half the width of the rim main body 3 .

[0071] Therefore, setting the axial width of the reinforcement part 31 to be greater than half of the axial width of the rim main body 3 can make the axial width of the reinforcement part 31 account for a larger proportion, which can significantly improve the overall structural strength of the rim to resist various forces and moments from the tire and the road surface, thereby extending the service life of the rim, and can better support the tire, reduce the deformation and wear of the tire during driving, thereby improving the stability and handling of the vehicle, and enhancing its durability. During long-term use, the rim can better withstand the stress and deformation under various complex working conditions, reduce the risk of damage and failure, and thus improve the collision performance of the entire vehicle.

[0072] Through simulation and theoretical calculation, it can be seen that every 45% increase in the rim mass (the mass of the reinforced part 31) can increase the rim crushing peak force by 86% and the crushing absorption energy by 94%, which can effectively increase the tire crushing mechanical properties.

[0073] Specifically, the width of the reinforcement part 31 can be set to two-thirds, three-fifths, etc. of the width of the rim main body 3. In this way, the axial and axial structural strength of the reinforcement part 31 to the rim main body 3 can be improved, and the specific setting can be selected according to actual usage requirements.

[0074] In some embodiments, the reinforcement portion 31 is constructed in a ring shape and extends along the circumference of the rim main body 3. In this way, the circumference of the rim main body 3 can be reinforced by the reinforcement portion 31 to improve the structural strength of the rim main body 3, thereby improving the structural strength of the rim as a whole.

[0075] Specifically, the reinforcement portion 31 is annular and concentrically arranged with the rim body 3. The reinforcement portion 31 extends axially along the rim body 3, allowing the reinforcement portion 31 to be connected to the rim body 3 in the circumferential direction, thereby improving the reliability and stability of the connection between the two. Furthermore, the reinforcement portion 31 is integrally formed with the rim body 3, thereby enhancing the structural strength of the rim body 3 and the reinforcement portion 31. Furthermore, the number of connection steps can be reduced, thereby improving production costs.

[0076] Among them, it should be noted that, by setting a plurality of reinforcing ribs 311 on the rim main body 3 or setting an integral reinforcing part 31 in the central area thereof, the structural strength of the rim main body 3 can be enhanced, and it is applicable to various types of metals (steel, aluminum alloy, magnesium alloy, titanium alloy, etc.) and non-metallic wheel materials (carbon fiber, plastic, etc.). When a carbon fiber rim is used, the rim shape is easier to process and the weight can be further reduced by about 40%. The use effect is good, and the material selection is diversified, the scope of application is wider, and the safety is higher.

[0077] The utility model also provides a wheel.

[0078] The wheel according to the embodiment of the present invention includes the rim 100 of the wheel of any of the above embodiments. The wheel also includes components such as a hub and spokes. The rim is used to install the tire and support the weight of the vehicle. The spokes are supporting components between the axle and the rim, and play the role of connecting the rim and the hub. By using the rim, spokes and spokes in combination, a complete wheel can be formed.

[0079] Furthermore, by providing a reinforcement portion 31 on the rim, with a radial thickness greater than that of the remaining rim portion 32, the rim's structural strength is enhanced while slightly increasing its weight. This significantly improves the vehicle's resistance to frontal collisions, enhancing overall vehicle strength. It also strengthens the underbody force transmission path, ensuring a smooth wheel-to-sill force transmission path during a frontal collision, and enhancing the vehicle's collision safety and reliability. Furthermore, by strengthening parts of the rim's structure, the overall structure is less bulky, meeting lightweight design requirements. Furthermore, a lightweight rim can reduce overall vehicle weight, thereby improving fuel efficiency and handling performance.

[0080] The utility model also provides a vehicle.

[0081] The vehicle according to the embodiment of the present invention includes the wheel of the above embodiment. The wheel is an important component of the vehicle driving system. The wheel includes the rim 100 of the above wheel. By providing a reinforcement portion 31 on the rim, and the radial thickness of the reinforcement portion 31 is greater than the radial thickness of the other portions 32 of the rim, the structural strength of the rim is improved while slightly increasing the weight of the rim. This can greatly improve the vehicle's resistance to frontal collisions, enhance the strength of the entire vehicle, and enhance the lower body force transmission path. This can effectively alleviate the force transmission pressure of the A-pillar during a collision, making the upper and lower force transmission paths of the body more balanced. For heavier models such as MPVs, coupes, and SUVs, this can effectively improve the passenger compartment's anti-intrusion capability (reduce the amount of intrusion from the upper body). For 100% head-on collisions, 25% offset collisions, and 40% offset collisions, the wheel will not tilt (fly out) rapidly during a collision, ensuring the smoothness of the wheel-door force transmission path, thereby increasing the vehicle's collision safety performance and reliability. By strengthening part of the rim structure, the overall structure will not be thick and heavy, meeting the requirements of lightweight settings. Lightweight rims can also reduce the weight of the entire vehicle, thereby improving fuel efficiency and handling performance.
