Nylon suspension and its manufacturing method, manufacturing system, and vehicles

[0001] Cross-reference to related applications

[0002] This application is based on and claims priority to Chinese Patent Application No. 202410787485.7, filed on June 18, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of suspension technology, and in particular to nylon suspensions and their manufacturing methods, manufacturing systems, and vehicles. Background Technology

[0004] Engine mounts are automotive powertrain components used to reduce and control the transmission of engine vibrations and to provide support. Currently, against the backdrop of the energy and environmental crisis, automakers worldwide are vigorously promoting the research and development of new energy vehicles. Compared to traditional gasoline vehicles, electric vehicles have the advantages of zero emissions and low noise; however, electric vehicles have higher requirements for their motor mount systems compared to gasoline vehicles. Furthermore, with the development of electric vehicles and consumers' increasing demands for vehicle quality, the motor mount system, as a crucial component affecting noise, vibration, and harshness (NVH), is receiving increasing attention from major manufacturers.

[0005] The issue of motor whine in electric vehicle suspensions is a major NVH (Noise, Vibration, and Harshness) pain point for current electric vehicles. Solving this high-frequency whine problem has become a key focus for major manufacturers, with some currently opting for a dual-stage vibration isolation solution. While existing dual-stage vibration isolation solutions can improve the high-frequency vibration isolation performance of the suspension system to some extent and enhance driving comfort, they are structurally complex, require significant design space, and are costly. Summary of the Invention

[0006] This application aims to at least partially solve one of the technical problems existing in the aforementioned technologies. To this end, this application proposes a nylon suspension and its manufacturing method, manufacturing system, and vehicle.

[0007] The solution to the technical problem in this application is:

[0008] A nylon suspension comprising:

[0009] A nylon bracket is provided with a first mounting hole and a second mounting hole, both of which penetrate the nylon bracket along a first direction.

[0010] The main spring structure includes a main spring, a core, and a limiting adhesive. The main spring is connected to the first mounting hole, and the main spring has a third mounting hole that extends through the main spring along a first direction. The core is connected to the third mounting hole and partially protrudes from the third mounting hole. The limiting adhesive is sleeved on the outer periphery of the core.

[0011] An insert is provided, at least one of which is connected to the second mounting hole.

[0012] This application has at least the following beneficial effects: the nylon bracket and the main spring structure form a two-stage vibration isolation structure, which can improve the high-frequency vibration isolation performance of the vehicle's suspension system, thereby improving the overall NVH performance of the vehicle. Moreover, compared with the traditional two-stage vibration isolation scheme, the nylon bracket and the main spring structure are lighter and cheaper, and the nylon suspension made has the characteristics of simpler structure, lighter weight, and lower cost.

[0013] As a further improvement to the above technical solution, the insert has multiple bosses at both ends, with a gap between adjacent bosses. The second mounting hole has multiple grooves on its wall, with each boss corresponding to one of the grooves. The presence of bosses increases the contact area between the insert and the nylon support, thereby increasing the connection strength between them and enhancing the overall connection strength of the nylon suspension.

[0014] As a further improvement to the above technical solution, the main spring is connected to the wall of the first mounting hole using an adhesive. This arrangement increases the bonding strength between the main spring and the nylon bracket, thereby enhancing the overall strength of the nylon suspension.

[0015] As a further improvement to the above technical solution, the limiting adhesive is interference-fitted with the core. This configuration ensures a tight connection between the limiting adhesive and the core, preventing the limiting adhesive from easily detaching from the core and thus serving to limit movement and prevent abnormal noise.

[0016] A method for manufacturing a nylon suspension, applicable to the manufacture of a nylon suspension as described in any of the above technical solutions, includes the following steps:

[0017] The manufacturing data for the nylon bracket is designed based on the overall vehicle installation environment;

[0018] Computer-aided engineering analysis was performed on the production data;

[0019] Once the computer-aided engineering analysis is approved, a mold is made and a sample is manufactured based on the production data.

[0020] The nylon suspension prototypes produced through the above steps are suitable for the vehicle installation environment and meet the strength requirements. The obtained nylon suspensions can improve the high-frequency vibration isolation performance of the vehicle's suspension system, thereby improving the overall NVH performance of the vehicle. They also feature simpler structure, lighter weight, and lower cost.

[0021] As a further improvement to the above technical solution, the computer-aided engineering analysis of the production data includes the following steps:

[0022] The strength of the nylon suspension corresponding to the manufacturing data is analyzed according to isotropic computer-aided engineering.

[0023] When the isotropic computer-aided engineering analysis results meet the strength requirements, anisotropic computer-aided engineering analysis is performed.

[0024] Because computer-aided engineering analysis of nylon materials is quite difficult, we first analyze the strength according to isotropic properties, and then conduct anisotropic computer-aided engineering analysis based on the results of the isotropic computer-aided engineering analysis. This can shorten the design cycle of nylon suspension manufacturing data.

[0025] As a further improvement to the above technical solution, the anisotropic computer-aided engineering analysis includes the following steps:

[0026] Based on the isotropic computer-aided engineering analysis results, mold design and mold flow analysis are performed to obtain a standard model;

[0027] Substitute the material model data card into the standard model to perform the anisotropic computer-aided engineering analysis.

[0028] If the anisotropic computer-aided engineering analysis fails, return to the step of re-executing the manufacturing data of the nylon bracket based on the vehicle installation environment.

[0029] Anisotropic computer-aided engineering analysis allows for more accurate adjustments to manufacturing data, facilitating the acquisition of prototypes that meet strength requirements and shortening the design cycle.

[0030] As a further improvement to the above technical solution, the step of performing mold design and mold flow analysis based on the isotropic computer-aided engineering analysis results includes the following steps:

[0031] A standard model is built in the software based on the production data.

[0032] The standard model is simulated and filled using software, and model flow analysis is performed.

[0033] If the model flow analysis fails, return to and re-execute the step of building a standard model in the software based on the production data.

[0034] By following the steps above, a standard model that meets the strength requirements can be obtained, which is beneficial for subsequent adjustments to the production data.

[0035] As a further improvement to the above technical solution, the step of opening a mold and making a sample based on the manufacturing data includes the following steps:

[0036] Fabricate a nylon bracket injection mold based on the aforementioned manufacturing data;

[0037] The main spring and the core are connected by a vulcanization process, and an adhesive is coated on the outer surface of the main spring.

[0038] The main spring and insert are placed in the nylon bracket injection mold, and the nylon suspension is obtained by injection molding.

[0039] The above steps ensure a stable connection between the main spring, core, and nylon support, guaranteeing the strength of the entire nylon suspension.

[0040] As a further improvement to the above technical solution, the manufacturing method further includes the following steps:

[0041] The sample was subjected to vehicle testing and bench testing.

[0042] Conducting vehicle tests and bench tests can further ensure that the nylon suspension meets various requirements, thereby improving the safety performance of the entire vehicle.

[0043] A system for manufacturing nylon suspensions, employing the method for manufacturing nylon suspensions as described in any of the above technical solutions, wherein the system for manufacturing nylon suspensions comprises:

[0044] A data extraction module was created to extract manufacturing data for the nylon bracket based on the vehicle's installation environment.

[0045] A computer-aided engineering analysis module is used to perform computer-aided engineering analysis on the production data.

[0046] The mold making module is used to open molds and make samples based on the manufacturing data.

[0047] The nylon suspension manufacturing system enables the production of nylon suspensions. The resulting nylon suspensions improve the high-frequency vibration isolation performance of the suspension system while also offering advantages such as simple structure, light weight, and low cost.

[0048] A vehicle includes a nylon suspension as described in any of the above technical solutions. Because the nylon bracket and main spring structure of the nylon suspension form a two-stage vibration isolation structure, and compared to traditional two-stage vibration isolation solutions, it features a simpler structure, lighter weight, and lower cost, the vehicle exhibits excellent high-frequency vibration isolation performance, significantly improved overall NVH performance, and reduced overall vehicle weight and manufacturing costs.

[0062] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0063] Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application. The various technical features in this application can be combined with each other without contradicting each other.

[0064] Referring to Figures 1, 2 and 3, this application proposes a nylon suspension, including a nylon bracket 110, a main spring structure 120 and an insert 130, which can improve the high-frequency vibration isolation performance of the suspension system while having the advantages of simple structure, light weight and low cost.

[0065] In this embodiment, the nylon bracket 110 is provided with a first mounting hole and a second mounting hole, which extend along a first direction and penetrate through the nylon bracket 110. The main spring structure 120 includes a main spring 121, a core 122, and a limiting adhesive 123. The main spring 121 is disposed in the first mounting hole and is connected and fixed to the hole wall of the first mounting hole. The main spring 121 is provided with a third mounting hole, which also extends along the first direction and penetrates through the main spring 121. The core 122 is disposed at the third mounting hole and is connected to the hole wall of the third mounting hole. A portion of the core 122 protrudes outward from the third mounting hole, and the limiting adhesive 123 is sleeved on the outer periphery of the portion of the core 122 protruding from the third mounting hole. At least one insert 130 is provided, which is disposed in the second mounting hole and connected to the hole wall of the second mounting hole.

[0066] In this embodiment, the insert 130 is used to install connecting bolts when installing the whole vehicle. The insert 130 has a fourth mounting hole extending along the first direction in the middle, which is used to provide an installation position for the bolt.

[0067] In this embodiment, the shape of the nylon bracket 110 is set according to the vehicle installation environment and the installation strength requirements. In this embodiment, three inserts 130 are provided, and correspondingly, three second mounting holes are provided on the nylon bracket 110. The three second mounting holes are not on the same straight line, which can ensure that the nylon suspension has sufficient strength when installed on the vehicle and improve the connection stability.

[0068] In this embodiment, the core 122 and insert 130 are both made of aluminum, the limiting adhesive 123 is made of rubber, and the nylon bracket 110 is cast from nylon. The choice of materials further reduces the production cost of the nylon suspension and results in a lightweight design. Of course, the core 122 and insert 130 can also be made of other metals, such as iron, and the limiting adhesive 123 can be made of materials such as silicone.

[0069] In this embodiment, the nylon material used in the nylon bracket 110 is high-damping nylon. The difference in damping characteristics between this material and traditional standard nylon is shown in Figure 4. The dashed line in the figure represents the curve of the tangent value of the high-damping nylon material changing with temperature, while the dashed line represents the curve of the tangent value of the traditional standard nylon material changing with temperature. As can be seen from Figure 4, the tangent value of the high-damping nylon material is greater than that of the traditional standard nylon material at all temperatures. It is understood that high-damping nylon material is a material already existing in the art. Utilizing the damping characteristics of high-damping nylon material can further improve the high-frequency vibration isolation performance of the vehicle's suspension system, thereby improving the overall NVH performance of the vehicle.

[0070] The nylon mounts in this embodiment are mostly used in the mount systems of electric vehicles. The nylon bracket 110 and the main spring structure 120 form a two-stage vibration isolation structure, which is beneficial to improving the high-frequency vibration isolation performance of the mount system, thereby improving the NVH performance of the whole vehicle. Moreover, compared with the traditional two-stage vibration isolation scheme, it has the characteristics of simpler structure, lighter weight and lower cost.

[0071] In some embodiments, the insert 130 has multiple protrusions 131 at both ends, with a gap between adjacent protrusions 131. The second mounting hole has multiple grooves on its wall, with the protrusions 131 corresponding to the grooves. Specifically, two sets of protrusions 131 are symmetrically arranged at both ends of the insert 130, with a certain gap between the two sets of protrusions 131. Each set of protrusions 131 has multiple protrusions 131, and a gap is also left between adjacent protrusions 131 in the same set.

[0072] It is understandable that in the same group of bosses 131, the bosses 131 are arranged circumferentially around the central axis of the insert 130 on the outer periphery of the insert 130. The width of each boss 131 can be the same or different, and the gap width between the bosses 131 is equal.

[0073] Understandably, the protrusion 131 increases the contact area between the insert 130 and the nylon bracket 110, thereby increasing the connection strength between the insert 130 and the nylon bracket 110 and thus improving the connection strength of the entire nylon suspension.

[0074] In this embodiment, the structure of each insert 130 is the same, and the hole shape of each second mounting hole is the same.

[0075] In this embodiment, the three inserts 130 are all installed on the same side of the main spring structure 120. During the processing, the main spring 121 and the three inserts 130 are placed in the injection mold of the nylon bracket 110, and then the nylon bracket 110 is formed by injection molding. After injection molding is completed, the nylon bracket 110 is stably connected with the main spring 121 and the inserts 130.

[0076] It is understandable that the shape and assembly structure of the main spring 121 can be adjusted according to the actual conditions of the vehicle. In this embodiment, four slots are evenly arranged on the outer periphery of the main spring 121, with the slots opening outwards.

[0077] In some embodiments, an adhesive layer is provided on the outer periphery of the main spring 121. That is, after injection molding, an adhesive is provided between the hole wall of the first mounting hole and the main spring 121, and the hole wall of the first mounting hole and the main spring 121 are reinforced by the adhesive. This arrangement can increase the bonding strength between the main spring 121 and the nylon bracket 110, thereby improving the strength of the entire nylon suspension.

[0078] In some embodiments, the limiting adhesive 123 and the outer peripheral wall of the core 122 are assembled together by an interference fit, which can achieve a tight connection between the limiting adhesive 123 and the core 122, making it difficult for the limiting adhesive 123 to fall off the core 122, thus playing a role in limiting and preventing abnormal noise. In this embodiment, the inner hole of the limiting adhesive 123 for mounting the core 122 is polygonal, and the shape of the core 122 matches the shape of the inner hole of the limiting adhesive 123.

[0079] In this embodiment, the outer peripheral edge of the limiting adhesive 123 matches the edge of the nylon bracket 110 to adapt to the vehicle installation environment.

[0080] In this embodiment, the nylon support 110 has three arc-shaped edges. One of these edges has a larger radius than the other two. The two smaller-radius edges are located to the right of the larger-radius edge, and are situated above and below it, respectively. The two smaller-radius edges are connected to the larger-radius edge by straight lines, and are also connected by an arc-shaped edge that curves inward toward the side of the larger-radius edge. It is understood that the three arc-shaped edges, two straight lines, and one arc-shaped edge together form the boundary of the nylon support 110 in this embodiment.

[0081] This configuration adapts to the vehicle installation environment and meets strength requirements. The main spring structure 120 is located on one side of the arc edge with a larger radius. Of the three inserts 130, two inserts 130 are respectively located on one side of the two arc edges with smaller radii, while the third insert 130 is located in the middle of the arc edge.

[0082] Multiple weight-reducing grooves are provided on the nylon bracket 110, and the edges of the weight-reducing grooves form reinforcing ribs, which can ensure the strength of the nylon bracket 110 while reducing weight.

[0083] Secondly, this application provides a method for manufacturing a nylon suspension, which is applied to the manufacture of nylon suspensions as proposed in any of the embodiments of the first aspect. Specifically, it includes steps S100, S200 and S300. Referring to FIG5, the manufactured nylon suspension can improve the high-frequency vibration isolation performance of the suspension system while having the advantages of simple structure, light weight and low cost.

[0084] Step S100: Design the manufacturing data of the nylon bracket 110 based on the vehicle installation environment. It is understood that the manufacturing data of the nylon bracket 110 should be extracted based on the vehicle installation environment and designed according to strength requirements to ensure that the nylon bracket 110 has sufficient strength.

[0085] In this embodiment, the boundary of the nylon support 110 includes three arc-shaped edges, two straight edges, and one curved edge. The manufacturing data includes, but is not limited to, the radius of the three arc-shaped edges, the center position of the three arc-shaped edges, and the curvature of the curved edge. Specifically, the design follows the strength requirements shown in Tables 1 and 2.

[0086] Table 1 Vertical Limits and Misused Torque Requirements

[0087]

[0088] Table 2 Vertical fatigue and torque durability requirements

[0089]

[0090] Understandably, the strength requirements for nylon suspension can be adjusted based on the actual road conditions of the vehicle.

[0091] Step S200: Perform computer-aided engineering analysis on the production data.

[0092] Computer-aided engineering (CAE) is an approximate numerical analysis method that uses computers to help solve complex engineering and product structures, including problems related to structural strength, stiffness, buckling stability, dynamic response, thermal conduction, three-dimensional multibody contact, elastoplasticity, and other mechanical properties, as well as optimizing structural performance.

[0093] By using computer-aided engineering analysis to generate data, and with the help of computer analysis and calculation, the rationality of the design of the nylon bracket 110 can be ensured, the design cost can be reduced, the design and analysis cycle can be shortened, and it can also serve as a "virtual prototype" to predict the reliability of the nylon suspension throughout its entire life cycle.

[0094] In step S300, after the computer-aided engineering analysis is passed, a mold is opened and a sample is manufactured based on the production data. It is understood that if the computer-aided engineering analysis fails, the production data is readjusted and the computer-aided engineering analysis is performed again. After the computer-aided engineering analysis passes, a mold is opened for the nylon bracket 110 based on the adjusted production data to manufacture a nylon suspension sample, ensuring that the manufactured sample meets the strength requirements.

[0095] Understandably, due to the anisotropy of nylon materials, which differs from the isotropy of metallic materials, computer-aided engineering analysis of nylon materials is more difficult. In order to shorten the design cycle, the strength is first analyzed according to isotropic analysis, and then anisotropic computer-aided engineering analysis is performed based on the results of the isotropic computer-aided engineering analysis.

[0096] In this embodiment, step S200 specifically includes steps S210 and S220, as shown in Figure 6.

[0097] Step S210: Based on the isotropic computer-aided engineering analysis, the strength of the nylon suspension corresponding to the data is generated.

[0098] If the isotropic computer-aided engineering analysis results meet the strength requirements, proceed to step S220 to perform anisotropic computer-aided engineering analysis. Otherwise, return to step S100 and redesign the data.

[0099] Understandably, when the isotropic computer-aided engineering analysis results do not meet the strength requirements, the process returns to the step of designing the manufacturing data of the nylon bracket 110, adjusting the manufacturing data according to the isotropic computer-aided engineering analysis results, and then performing the isotropic computer-aided engineering analysis again until the isotropic computer-aided engineering analysis results meet the strength requirements.

[0100] In this embodiment, step S220 involves performing anisotropic computer-aided engineering analysis, including steps S221, S222, and S223, as shown in Figure 7.

[0101] Step S221: Based on the isotropic computer-aided engineering analysis results, perform mold design and mold flow analysis to obtain a standard model. Mold flow analysis essentially refers to using data simulation software to simulate the injection molding process using a computer, obtaining data results, and then evaluating the feasibility of the mold design to improve both the mold design and the product design.

[0102] In this embodiment, step S221 specifically includes the following steps: establishing a standard model in the software based on the production data, then simulating and filling the standard model using the software, and performing a model flow analysis. If the model flow analysis fails, return to the step of establishing a standard model in the software based on the production data until the model flow analysis passes, and then proceed to step S222.

[0103] In this embodiment, the infilling simulation is performed using software such as Moldflow and Moldex3D, and a standard model is established using software such as Ansys, Abaqus, and Ls-Dyna.

[0104] Step S222: Substitute the material model data card into the standard model to perform anisotropic computer-aided engineering analysis. It is understood that the material model data card is obtained through prior experiments.

[0105] Step S223: If the anisotropic computer-aided engineering analysis fails, return to the step of re-executing the manufacturing data of the nylon bracket 110 for the branch's whole vehicle installation environment design. It is understandable that if the anisotropic computer-aided engineering analysis fails, it means that the designed manufacturing data does not meet the requirements, so the manufacturing data needs to be adjusted. After adjusting the manufacturing data, isotropic computer-aided engineering analysis needs to be performed again, followed by anisotropic computer-aided engineering analysis, to ensure that the final obtained manufacturing data meets all requirements.

[0106] In this embodiment, step S300, after the computer-aided engineering analysis is passed, involves opening a mold and making a sample based on the manufacturing data. Specifically, it includes steps S310, S320, and S330, as shown in Figure 8.

[0107] Step S310: Fabricate an injection mold for the nylon support 110 based on the manufacturing data. The injection mold for the nylon support 110 is used for injection molding to obtain the nylon support 110. Since the manufacturing data has been subjected to computer-aided engineering analysis in advance, the nylon support 110 obtained by adjusting the manufacturing data according to the results of the computer-aided engineering analysis has sufficient strength.

[0108] In step S320, the main spring 121 is connected to the core 122 by a vulcanization process, and an adhesive is applied to the outer surface of the main spring 121.

[0109] Understandably, the vulcanization process connects the main spring 121 and the core 122. High temperatures transform the linear macromolecules of the main spring 121 into a network structure, enhancing its tensile strength, hardness, elasticity, and anti-aging properties. An adhesive is applied to the outer periphery of the main spring 121. After injection molding, the adhesive increases the bond strength between the main spring 121 and the nylon support 110, thereby improving the overall strength of the nylon suspension.

[0110] In step S330, the main spring 121 and the insert 130 are placed in the injection mold of the nylon bracket 110, and the nylon suspension is obtained by injection molding. The nylon bracket 110 is obtained by injection molding, which allows the main spring 121, the insert 130 and the nylon bracket 110 to be stably connected. The manufacturing process is simpler and more convenient, and the strength of the nylon suspension can be improved.

[0111] In some embodiments, to further ensure the strength of the nylon suspension and guarantee its safety in subsequent use, after obtaining the prototype, it is necessary to conduct vehicle tests and bench tests on the prototype. After passing the vehicle tests and bench tests, large-scale production can be carried out based on the prototype's manufacturing data, ensuring the pass rate of the nylon suspension.

[0112] Thirdly, this application also proposes a nylon suspension manufacturing system for performing the nylon suspension manufacturing method proposed in any of the embodiments of the second aspect, which can obtain nylon suspensions. The obtained nylon suspensions have the advantages of simple structure, light weight, and low cost while improving the high-frequency vibration isolation performance of the suspension system.

[0113] The nylon suspension fabrication system of this embodiment includes a fabrication data extraction module, a computer-aided engineering analysis module, and a mold-making module. The fabrication data extraction module extracts fabrication data for the nylon bracket 110 based on the vehicle installation environment, thereby designing the fabrication data and implementing step S100. The computer-aided engineering analysis module performs computer-aided engineering analysis on the fabrication data, implementing step S200. The mold-making module creates a mold and fabricates a prototype based on the fabrication data, implementing step S300.

[0114] In this embodiment, due to the anisotropy of nylon material, computer-aided engineering analysis is quite difficult. The computer-aided engineering analysis module includes software for isotropic computer-aided engineering analysis and software for anisotropic computer-aided engineering analysis. First, computer-aided engineering analysis is performed according to isotropic conditions, and after adjusting the manufacturing data, anisotropic computer-aided engineering analysis is performed to shorten the design cycle.

[0115] Fourthly, this application also proposes a vehicle that includes the nylon suspension proposed in any of the embodiments of the first aspect. Since the nylon bracket 110 of the nylon suspension and the main spring structure 120 form a dual-stage vibration isolation structure, and compared with traditional dual-stage vibration isolation schemes, it has the characteristics of simpler structure, lighter weight, and lower cost. Therefore, the vehicle has good high-frequency vibration isolation performance, the overall NVH performance of the vehicle is significantly improved, and the overall vehicle weight is reduced, thus reducing the overall vehicle production cost.

[0116] It is understood that the vehicles mentioned in this embodiment can be private cars, such as sedans, SUVs, MPVs, or pickup trucks. Vehicles can also be commercial vehicles, such as vans, buses, small trucks, or large semi-trailers. Vehicles can be gasoline-powered or new energy vehicles. When a vehicle is a new energy vehicle, it can be a hybrid or a pure electric vehicle.

[0117] The preferred embodiments of this application have been described in detail above, but the invention of this application is not limited to the embodiments described.
