[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. 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.

[0019] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0020] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0021] refer to Figures 1 to 8 This application discloses a suspension assembly applied to a vehicle. The suspension assembly can be used for mounting a transmission (not shown) to a vehicle body (not shown), and also for mounting an engine (not shown) to a vehicle body. In addition, the suspension assembly can be applied to other scenarios, which are not specifically limited here. The disclosed suspension assembly includes a first bracket 10, a second bracket 20, a bushing assembly 30, and a buffer assembly 40.

[0022] The first support 10 is a basic component that provides a load-bearing foundation for components such as the bushing assembly 30, the buffer assembly 40, and the second support 20. The first support 10 may be provided with a first mounting hole 11, such as... Figure 5 As shown, the bushing assembly 30 is installed in the first mounting hole 11 to realize the assembly of the bushing assembly 30 and the first bracket 10.

[0023] Optionally, the first bracket 10 can be a long, narrow bracket; the second bracket 20 can be a concave shell shape with a certain cavity to facilitate fastening to the transmission without causing assembly interference. Of course, the first bracket 10 and the second bracket 20 can each adopt other shapes, which are not specifically limited here. In some more specific embodiments, the first bracket 10 can be an integral structure, such as an integral stamped part or an integral injection molded part.

[0024] In some more specific embodiments, the first bracket 10 can be a long strip structure, and the first mounting hole 11 can be opened on the surface of the long strip structure and penetrate through the two opposite surfaces of the long strip structure, so that the axis of the first mounting hole 11 can be parallel to the extension direction of the long strip surface.

[0025] Optionally, the bushing assembly 30 can be installed into the first mounting hole 11 using an interference fit to ensure the stability and reliability of the assembly between the bushing assembly 30 and the first bracket 10, effectively preventing the bushing assembly 30 from arbitrarily dislodging from the first mounting hole 11. This can be achieved by pressing the bushing assembly into the first mounting hole 11 using a press-fitting device.

[0026] The second bracket 20 is connected to the bushing assembly 30, allowing the second bracket 20 to be flexibly connected to the first bracket 10 via the bushing assembly 30. In this way, the bushing assembly 30 acts as a connection and buffer between the first bracket 10 and the second bracket 20, preventing direct collisions between them that could generate noise, vibration, or even damage to components. It should be noted that at least some components of the bushing assembly 30 can be made of flexible materials, such as rubber or plastic, to achieve a flexible connection with the second bracket 20.

[0027] Optionally, when the mounting assembly is applied between the transmission and the vehicle body, or between the engine and the vehicle body, the first bracket 10 and the second bracket 20 can be separated by the bushing assembly 30 to prevent the vibration generated by the transmission or engine from being transmitted to the vehicle body, since the transmission or engine will vibrate during operation. Of course, during vehicle operation, uneven road surfaces may cause the vehicle body to sway. In this case, the bushing assembly 30 can also help reduce the degree of swaying of the transmission or engine by acting as a buffer.

[0028] For example, the bushing assembly 30 may include an inner core, a rubber body, an outer tube, a limiting pad, and a limiting plate. The inner core can be connected to the second bracket 20, the outer tube can be installed into the first mounting hole 11, the rubber body can be located between the inner core and the outer tube, and the limiting pad and the limiting plate both limit the relative movement between the inner core and the outer tube to ensure that the inner core and the outer tube do not move excessively or detach. It should be noted that the structure and working principle of the bushing assembly 30 can also be derived from other existing technologies.

[0029] refer to Figure 1 and Figure 2 The buffer assembly 40 is disposed between the first support 10 and the second support 20 to further buffer the first support 10 and the second support 20.

[0030] It should be noted that, considering the significant relative acceleration between the transmission or engine and the vehicle body during acceleration or braking, the first bracket 10 and the second bracket 20 are prone to relative movement. Therefore, when installing the suspension assembly, the first bracket 10 and the second bracket 20 can be arranged along the longitudinal direction of the vehicle. Simultaneously, a buffer assembly 40 can be positioned between the first bracket 10 and the second bracket 20 in the longitudinal direction. This buffer assembly 40 can thus cushion the first bracket 10 and the second bracket 20 in the longitudinal direction, reducing their relative movement and preventing collisions.

[0031] Of course, in other embodiments, the first support 10 and the second support 20 may be distributed in other ways, and the buffer component 40 is also set in a different way to buffer between the first support 10 and the second support 20.

[0032] In this embodiment, the first bracket 10 can support and install the bushing assembly 30, and the bushing assembly 30 can support and install the second bracket 20, and the bushing assembly 30 can buffer and dampen the second bracket 20. Furthermore, a buffer assembly 40 is provided between the first bracket 10 and the second bracket 20, so that the first bracket 10 and the second bracket 20 can play a further buffering role during relative movement, so as to prevent collisions caused by excessive relative movement.

[0033] Compared to the transmission mount assemblies in related technologies, which use components such as left mount frame, right mount frame, mount bracket, bushing, and bolts for assembly, the embodiments of this application can integrate the left mount frame and right mount frame. Compared to the transmission mount assemblies in related technologies, the embodiments of this application use an integrated first bracket 10, which not only reduces the number of parts and weight, but also enables integrated manufacturing. This reduces investment in mold development, simplifies assembly processes, reduces the complexity of production, assembly, and maintenance, improves production efficiency, and reduces costs. Furthermore, the cooperation between the buffer assembly 40 and the bushing assembly 30 can further improve the buffering effect and alleviate vibration and collision problems.

[0034] refer to Figures 1 to 5 In some embodiments, the first bracket 10 may be provided with a plurality of first mounting holes 11, the plurality of first mounting holes 11 being arranged along the extending direction of the first bracket 10, each first mounting hole 11 being provided with a bushing assembly 30, and the plurality of bushing assemblies 30 being respectively connected to the second bracket 20.

[0035] Based on the above configuration, the first support 10 and the second support 20 can be connected through multiple bushing assemblies 30, and the second support 20 can be supported and fixed, thereby improving the reliability of support and fixation, and further ensuring the connection stability and reliability of the second support 20.

[0036] In some more specific embodiments, the first bracket 10 may have two first mounting holes 11, and the two first mounting holes 11 are symmetrically arranged in the extending direction of the first bracket 10, making the first bracket 10 with two first mounting holes 11 look similar to an eyeglass structure. Based on this, a reliable shape can be maintained when supporting and fixing the bushing assembly 30, and it is not easy to deform or loosen. This allows the first bracket 10 to reduce unnecessary material use in the overall outline while ensuring strength, which is beneficial to reducing the overall weight of the first bracket 10. In addition, the shape of this type of first bracket 10 is relatively simple and beautiful, while also having a certain degree of flexibility. While ensuring functionality, it also takes into account the appearance design, making the first bracket 10 not only practical but also aesthetically pleasing. Furthermore, it can reduce the types of mold cavities to be developed, reduce the complexity of the process, and increase the service life of the mold cavities, which is beneficial to reducing cost investment and improving efficiency.

[0037] The bushing assemblies 30 installed in the two first mounting holes 11 provide dual-point support and dual-point connection for the second bracket 20, which can improve the overall strength and rigidity of the bushing assemblies 30, reduce vibration transmission, and improve the installation stability of the second bracket 20.

[0038] In other embodiments, the first bracket 10 may also be provided with other numbers of first mounting holes 11 and in other arrangements. Accordingly, each first mounting hole 11 may be equipped with a bushing assembly 30, as long as the requirements are met, the specific number and arrangement are not limited.

[0039] refer to Figures 1 to 4 In some embodiments, the sidewall of the first bracket 10 may be provided with multiple first reinforcing ribs 12, which are arranged at intervals along the axial direction of the first mounting hole 11, wherein the axial direction is perpendicular to the extension direction, each first reinforcing rib 12 extends along the extension direction of the first bracket 10, and each first reinforcing rib 12 passes through the outer wall area of ​​multiple first mounting holes 11.

[0040] For example, such as Figure 4As shown, the first mounting hole 11 can be formed on the top surface of the first bracket 10 and penetrate through the bottom surface of the first bracket 10; the first reinforcing ribs 12 can be provided on the front side wall and the rear side wall of the first bracket 10. Based on this design, the situation where the first reinforcing rib 12 blocks the first mounting hole 11 can be effectively avoided, so that both the overall strength of the first bracket 10 can be improved and the bushing assembly 30 can be smoothly installed into the first mounting hole 11 to prevent interference between the bushing assembly 30 and the first reinforcing rib 12.

[0041] Based on the above settings, through multiple first reinforcing ribs 12, the force on the first bracket 10 can be dispersed in multiple directions, which is beneficial to enhancing the compressive, tensile and anti-twisting capabilities of the structure of the first bracket 10, making the overall structure of the first bracket 10 more stable and not easily deformed; moreover, it can effectively increase the bearing load of the first bracket 10. When bearing a large weight or pressure, it can better maintain its shape and reduce the risk of damage; through the reasonable structural layout of multiple first reinforcing ribs 12, on the premise of ensuring strength, the amount of material used can be reduced, the cost can be lowered, the quality can be reduced, the stiffness and mode of the first bracket 10 can be improved, and the vibration transmission can be reduced.

[0042] Reference Figure 3 and Figure 4 , in some more specific embodiments, three first reinforcing ribs 12 can be respectively provided on the opposite side walls of the first bracket 10. Among the three first reinforcing ribs 12 on each side wall, the middle first reinforcing rib 12 can be a straight reinforcing rib, and both ends of the first reinforcing ribs 12 on both sides can be bent in the direction away from the middle respectively. Thus, the three first reinforcing ribs 12 can form a "chuan" character structure. This layout method can increase the distribution area of the first reinforcing ribs 12, thereby further improving the anti-bearing capacity of the first bracket 10. Of course, in other embodiments, other numbers of first reinforcing ribs 12 can also be respectively provided on the opposite side walls of the first bracket 10, which can be specifically set according to the actual situation.

[0043] In order to install the first bracket 10 to the vehicle body, the first bracket 10 can be provided with multiple fixing holes 13. Along the extending direction of the first bracket 10, the multiple fixing holes 13 can be distributed at both ends of the first bracket 10, as Figures 1 to 4 shown. Based on this, the setting position of the first mounting hole 11 can be avoided; a fastener is inserted into each fixing hole 13 and the fastener is installed on the vehicle body to fasten the first bracket 10 to the vehicle body through the fastener, ensuring the installation stability and reliability of the first bracket 10. Exemplarily, the fastener can be a fastening bolt, a fastening screw, etc.

[0044] Optionally, the fixing hole 13 can penetrate through the first bracket 10 along the thickness direction of the first bracket 10.

[0045] In other embodiments, the first bracket 10 can also be fixed to the vehicle body by welding, riveting or other methods to ensure the firmness and reliability of the connection between the first bracket 10 and the vehicle body.

[0046] Furthermore, both ends of each first reinforcing rib 12 can extend to the area near the fixing hole 13, thereby further expanding the area covered by the first reinforcing rib 12 and thus further improving the overall strength of the first bracket 10.

[0047] In this embodiment, the first reinforcing rib 12 passes through both the location of the first mounting hole 11 and the location of the fixing hole 13, thereby reinforcing the locations of the first mounting hole 11 and the fixing hole 13 to prevent the first bracket 10 from breaking at the weak points of the first mounting hole 11 and the fixing hole 13 when bearing a load.

[0048] In some embodiments, the first reinforcing rib 12 can be fixedly disposed on the side wall of the first bracket 10, for example, by welding, bonding, riveting, etc.; of course, the first reinforcing rib 12 and the first bracket 10 can also be integrally disposed, that is, the first reinforcing rib 12 is formed together during the manufacturing process of the first bracket 10, so as to improve the overall strength of the first bracket 10 and the first reinforcing rib 12.

[0049] refer to Figure 6 and Figure 7 In some embodiments, the second bracket 20 may be provided with multiple second mounting holes 21. Considering that the second bracket 20 can be connected to both the bushing assembly 30 and the transmission, a portion of the multiple second mounting holes 21 can be used for connecting the second bracket 20 and the bushing assembly 30, while another portion can be used for connecting the second bracket 20 to the transmission. The axis of the second mounting hole 21 may be parallel to the axis of the first mounting hole 11.

[0050] Optionally, a portion of the second mounting hole 21 used for connecting the second bracket 20 to the bushing assembly 30 can be a threaded hole to facilitate the installation of threaded fasteners. The threaded hole can be a through hole or a blind hole, depending on the actual requirements. Another portion of the second mounting hole 21 used for connecting the second bracket 20 to the gearbox can be a through hole to allow fasteners to pass through.

[0051] Additionally, the second bracket 20 may also be provided with a fourth mounting hole 23, such as... Figure 1 and Figure 2 As shown, the axis of the fourth mounting hole 23 is perpendicular to the axis of the second mounting hole 21. Thus, the second bracket 20 is installed to the transmission or engine through the fasteners in the fourth mounting hole 23 and the second mounting hole 21, thereby achieving multi-directional fastening and improving the installation stability of the second bracket 20.

[0052] In this embodiment of the application, a second reinforcing rib 22 can be connected between any second mounting hole 21 and the surrounding adjacent second mounting holes 21. In this way, the second reinforcing rib 22 can strengthen the area where any second mounting hole 21 is located, and can also strengthen the area between any second mounting hole 21 and the surrounding adjacent second mounting holes 21, thereby improving the overall strength of the second bracket 20 and improving the overall load-bearing capacity of the second bracket 20.

[0053] Optionally, the second bracket 20 may have a first side and a second side disposed opposite to each other, wherein the first side is disposed toward the first bracket 10, and the second side is disposed away from the first bracket 10 and toward the transmission or engine.

[0054] In some embodiments, the second reinforcing rib 22 may be distributed on the side of the second bracket 20 away from the first bracket 10, that is, the second reinforcing rib 22 is disposed on the second side of the second bracket 20 to prevent the second reinforcing rib 22 from interfering with the first bracket 10 and the bushing assembly 30.

[0055] Furthermore, the side of the second support 20 facing away from the first support 10 is divided into multiple triangular regions by multiple second reinforcing ribs 22, such as... Figure 7 As shown, the stability and non-deformation properties of triangles can be utilized to improve the strength and stiffness of the second support 20 and reduce the vibration transmission of the second support 20.

[0056] refer to Figure 6 and Figure 7 In some embodiments, at least a portion of the plurality of second mounting holes 21, i.e., a portion of the second mounting holes 21 used for connecting the second bracket 20 to the bushing assembly 30, may be threaded holes; correspondingly, the suspension assembly may also include a threaded fastener (not shown in the figure) that passes through the bushing assembly 30 and connects to the threaded hole. Based on this, a detachable connection between the second bracket 20 and the bushing assembly 30 can be achieved, ensuring the stability and reliability of the connection between the two, and facilitating disassembly and assembly for maintenance of the transmission or engine.

[0057] In some embodiments, the second bracket 20 may also be fixed to the transmission or engine by welding, riveting, screwing, or other methods to ensure the firmness and reliability of the connection between the second bracket 20 and the transmission or engine.

[0058] To enable the connection between the buffer assembly 40 and the first bracket 10, the first bracket 10 may also be provided with a third mounting hole 14, such as... Figure 5As shown, the axis of the third mounting hole 14 is parallel to the axis of the first mounting hole 11, allowing the third mounting hole 14 to be positioned opposite the second bracket 20. A portion of the buffer assembly 40 can be mounted to the third mounting hole 14 to facilitate stable installation of the buffer assembly 40. For example, the axes of both the first mounting hole 11 and the third mounting hole 14 can extend along the longitudinal direction of the vehicle body to facilitate buffering in the longitudinal direction of the vehicle body via the buffer assembly 40.

[0059] refer to Figures 2 to 5 , Figure 8 In some embodiments, the buffer assembly 40 may include a mounting rod 41 and a buffer end 42. One end of the mounting rod 41 is inserted into the third mounting hole 14, and the buffer end 42 is connected to the other end of the mounting rod 41 and is disposed opposite to the second bracket 20. Based on this, the cooperation between the mounting rod 41 and the third mounting hole 14 can achieve stable installation of the buffer assembly 40 and the first bracket 10, and the buffer end 42 can limit and buffer the second bracket 20 to prevent the second bracket 20 from colliding with the first bracket 10 due to excessive proximity.

[0060] It should be noted that when the vehicle is stationary, the end of the buffer end 42 facing away from the mounting rod 41 can be spaced apart from or in contact with the second bracket 20. As the vehicle moves, the second bracket 20 can move closer to the first bracket 10 and drive the bushing assembly 30 to move. In this way, the second bracket 20 can squeeze the buffer end 42, causing the buffer end 42 to undergo elastic deformation, so as to limit and buffer the second bracket 20 through the buffer end 42, preventing the second bracket 20 from contacting the first bracket 10.

[0061] For example, the buffer end 42 can be a frustum structure, a truncated pyramid structure, etc. Of course, the buffer end 42 can also be other shapes, which are not specifically limited here.

[0062] In some more specific embodiments, the outer peripheral surface of the buffer end 42 may be provided with a spiral structure 421, such as... Figure 8 As shown, this can distribute the force borne by the buffer end 42 to the entire buffer end 42, thereby reducing the problem of localized concentrated force on the outer peripheral surface of the buffer end 42. This is beneficial to improving the fatigue resistance of the buffer end 42 under dynamic or alternating loads, making the buffer end 42 less prone to damage, and extending the service life of the buffer end 42.

[0063] Optionally, the helical structure 421 can be a helical groove, or the helical structure 421 can be a helical protrusion. In addition, the helical structure 421 can also be in other forms, which are not specifically limited here.

[0064] In other more specific embodiments, the outer peripheral surface of the buffer end 42 may be provided with a multi-layered annular structure arranged along the center line of the buffer end 42. In this way, the force borne by the buffer end 42 can be distributed to the multi-layered annular structure to alleviate the problem of localized concentrated force on the outer peripheral surface of the buffer end 42. This is beneficial to improving the fatigue resistance of the buffer end 42 under dynamic or alternating loads, making the buffer end 42 less prone to damage, and extending the service life of the buffer end 42.

[0065] Optionally, the annular structure can be an annular groove, or it can be an annular protrusion. Other forms of the annular structure are not specifically limited here.

[0066] In addition, the outer diameter of the buffer end 42 can be gradually increased along the direction from the second support 20 to the first support 10. This can change the stiffness of the gradient section, so as to provide a more flexible buffering effect under compression, tension or torsion and improve the vibration reduction effect.

[0067] The buffer end 42 in this embodiment can utilize the elastic deformation of the spiral structure 421 to improve the adaptability of the buffer end 42 in three-dimensional space. The strength of different parts can be adjusted by the change in stiffness of the gradually changing cross section, so that the buffer end 42 can simultaneously cope with loads in multiple directions such as axial and radial directions, making the application scenarios of the buffer end 42 more extensive.

[0068] In some embodiments, the first bracket 10 may be made of magnesium alloy, which ensures sufficient strength, improves corrosion resistance, and reduces weight, thus facilitating lightweight vehicle design. Additionally, the first bracket 10 may be manufactured using a casting process to improve manufacturing efficiency and reduce manufacturing costs.

[0069] The second bracket 20 can be made of aluminum alloy, which ensures sufficient strength, improves corrosion resistance, and reduces weight, thus facilitating lightweight vehicle design. Furthermore, the second bracket 20 can be manufactured using a casting process to improve manufacturing efficiency and reduce costs.

[0070] Of course, the first support 10 and the second support 20 can each be made of carbon fiber reinforced plastic, etc.

[0071] Based on the above-described mounting assembly, this application also discloses a vehicle, which includes a body (not shown in the figure), a transmission (not shown in the figure), and the above-described mounting assembly.

[0072] Among them, the first bracket 10 is connected to the vehicle body, and the second bracket 20 is connected to the transmission. In this way, the transmission can be reliably mounted to the vehicle body through the mounting assembly, and it can play a certain buffering and vibration damping role between the transmission and the vehicle body, which is beneficial to improving the service life and quality of the vehicle.

[0073] In summary, the first bracket 10 in the embodiment of the present application adopts a glasses-type structure design and is strengthened in a zigzag shape, achieving a balance between lightweight and high strength; through the design of the buffer component 40, the vibration damping effect between the first bracket 10 and the second bracket 20 can be improved; through the screw connection of the first bracket 10 and the bushing component 30 and the integrated design of the first bracket 10, the assembly process can be simplified, the production efficiency can be improved, and the overall cost can be effectively controlled; in addition, both the first bracket 10 and the second bracket 20 adopt high-strength and lightweight materials, which is beneficial to promoting the lightweight development of the vehicle and improving the fuel economy and handling performance of the vehicle.

[0074] The embodiments of the present application have been described above in conjunction with the accompanying drawings. However, the present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
