[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] The following is for reference. Figures 1-3 This invention describes a bushing device 100, a suspension system, and a vehicle according to an embodiment of the present invention. The bushing device 100 according to an embodiment of the present invention includes: an outer frame 10 and an inner frame 20, the outer frame 10 being fitted onto the inner frame 20; a bushing body 30, the bushing body 30 including an elastic body 31 and an assembly 33, the elastic body 31 having a through hole 32, the bushing body 30 being located between the outer frame 10 and the inner frame 20, and the bushing body 30 being fitted onto the inner frame 20, the assembly 33 being fixedly connected to the elastic body 31 and located on the side of the elastic body 31 facing away from the inner frame 20, and the assembly 33 facing the outer frame 10. The outer frame 10 has one of the mounting grooves 11 and mounting protrusions 34 formed on its surface, and the other of the mounting grooves 11 and mounting protrusions 34 formed on its inner surface. The mounting grooves 11 penetrate the bushing device 100 along its axial direction. There are multiple mounting grooves 11 and mounting protrusions 34. The multiple mounting grooves 11 and multiple mounting protrusions 34 are arranged circumferentially along the elastic body 31. The mounting protrusions 34 can move into or out of the corresponding mounting grooves 11 along the axial direction of the bushing device 100 to adjust the relative position of the through hole 32 and the outer frame 10.

[0029] Both the outer frame 10 and the inner frame 20 are metal components, such as steel or aluminum alloy, to ensure their strength and durability. The outer frame 10 is fitted over the inner frame 20, protecting it from corrosion and wear, and preventing direct contact between external objects and the inner frame 20, thus reducing potential malfunctions and damage. As the external support structure of the bushing body 30, the outer frame 10 fixes and supports both the bushing body 30 and the inner frame 20, providing additional strength and stability to ensure they can withstand external pressure and loads. The bushing body 30 is an important component of the bushing device 100. The bushing body 30 is located between the outer frame 10 and the inner frame 20, and the bushing body 30 is fitted onto the inner frame 20. The bushing body 30 is connected between the outer frame 10 and the inner frame 20 so that the bushing body 30 plays the role of filling and supporting. The bushing body 30 can absorb and buffer external impacts and vibrations, and improve the shock resistance and stability of the suspension system.

[0030] The bushing body 30 and the outer frame 10 are detachably connected, enabling quick assembly and disassembly of the bushing body 30. When the bushing body 30 or the outer frame 10 is worn or damaged, the detachable design allows technicians to quickly disassemble and replace the damaged parts without replacing the entire bushing assembly 100, significantly shortening maintenance time, reducing maintenance costs, and improving the maintainability of the bushing assembly 100. Furthermore, the detachable connection between the bushing body 30 and the outer frame 10 facilitates adjustment of the position and angle of the through holes, allowing for adjustment of the stiffness of the bushing assembly 100 to suit vehicles with different stiffness requirements. This enhances the versatility of the bushing assembly 100, reduces costs, improves vehicle comfort and handling, and ultimately enhances overall vehicle performance.

[0031] The bushing body 30 includes an elastomer 31 and an assembly 33. The elastomer 31 can be made of polymer materials, rubber, plastics, etc. This application uses rubber as an example for illustration. The rubber elastomer 31 has advantages such as elasticity, resilience, vibration damping and isolation performance, wear resistance, and durability. Moreover, the rubber elastomer 31 is conducive to the lightweight design of the bushing device 100 and also helps to reduce the manufacturing cost of the bushing device 100. This allows the bushing body 30 to absorb and reduce external impacts and vibrations, effectively reducing the damage to the suspension system caused by vibration and impact. Furthermore, the bushing body 30 can maintain stable performance when subjected to repeated loads and friction, which helps to extend the service life of the bushing body 30.

[0032] The elastomer 31 has a through hole 32, which reduces the weight of the bushing body 30, thereby effectively reducing the load on the bushing device 100. This helps reduce vehicle energy consumption, improves vehicle handling and acceleration performance, and also effectively reduces the stiffness of the bushing body 30, thereby improving the vibration isolation performance of the bushing device 100 and thus effectively improving the overall vehicle vibration noise and NVH performance. In addition, since the bushing body 30 and the outer frame 10 are detachably connected, the position and angle of the through hole 32 can be adjusted at any time by disassembling and assembling the bushing body 30, thereby adjusting the stiffness of the bushing device 100 to be applied to vehicles with different stiffness requirements. This improves the versatility of the bushing device 100, reduces costs, and also improves vehicle comfort and handling, thus improving the overall vehicle performance.

[0033] Assembly 33 may have structures such as splines and connecting plates, but this utility model is not limited to these. Assembly 33 may also have other structures. This application uses assembly 33 as a spline as an example for description. Assembly 33 and elastic body 31 are fixedly connected and located on the side of elastic body 31 away from inner frame 20. For example, assembly 33 and elastic body 31 can be fixedly connected by adhesive bonding, or assembly 33 and elastic body 31 can be fixedly connected by vulcanization molding process. However, this utility model is not limited to these. Assembly 33 and elastic body 31 can also be fixedly connected by other means, as long as assembly 33 and elastic body 31 are fixedly connected and located on the side of elastic body 31 away from inner frame 20. This application uses the example of a fixed connection between assembly 33 and elastomer 31 via vulcanization molding to illustrate this. This not only improves the connection strength between elastomer 31 and assembly 33 and reduces the risk of loosening or falling off, but is also applicable to inner skeletons 20 of various shapes and sizes, as well as different types of elastomers 31, thereby reducing the difficulty of connecting elastomer 31 and assembly 33.

[0034] The assembly 33 and the outer frame 10 are detachably connected. For example, the assembly 33 and the outer frame 10 can be connected by a spline sleeve, pin, bolt, or other structure, making the assembly 33 and the outer frame 10 detachably connected. This detachable connection allows the bushing body 30 to be disassembled from the outer frame 10, enabling quick assembly and disassembly of the bushing body 30 without the need for specialized hydraulic equipment. When the bushing body 30 or the outer frame 10 is worn or damaged, the detachable connection design allows technicians to quickly disassemble and replace the damaged parts without replacing the entire bushing assembly 100, significantly shortening maintenance time, reducing maintenance costs, and improving the maintainability of the bushing assembly 100.

[0035] Furthermore, by disassembling and assembling the bushing body 30, the position and angle of the through hole 32 can be adjusted at any time to adjust the stiffness of the bushing device 100 to meet the needs of vehicles with different stiffness requirements. This can improve the versatility of the bushing device 100, reduce vehicle development costs, balance vehicle comfort and handling, and thus improve the overall vehicle performance.

[0036] The surface of the assembly 33 facing the outer frame 10 has one of a mounting groove 11 and a mounting protrusion 34, and the inner surface of the outer frame 10 has the other of a mounting groove 11 and a mounting protrusion 34. For example, the surface of the assembly 33 facing the outer frame 10 has a mounting groove 11 and the inner surface of the outer frame 10 has a mounting protrusion 34, or the surface of the assembly 33 facing the outer frame 10 has a mounting protrusion 34 and the inner surface of the outer frame 10 has a mounting groove 11. This application will describe the assembly 33 with a mounting protrusion 34 on the surface facing the outer frame 10 and a mounting groove 11 on the inner surface of the outer frame 10 as an example. The mounting groove 11 extends through the bushing device 100 along its axial direction. There can be multiple mounting grooves 11 and mounting protrusions 34, for example, there can be six, eight, ten or other numbers of mounting grooves 11 and mounting protrusions 34. However, this utility model is not limited to this, and there can be other numbers of mounting grooves 11 and mounting protrusions 34, as long as there are multiple mounting grooves 11 and mounting protrusions 34.

[0037] Multiple mounting slots 11 and multiple mounting protrusions 34 are arranged circumferentially along the elastic body 31. The mounting protrusions 34 are assembled into the corresponding mounting slots 11, which can fix the assembly 33 and the outer frame 10 through the cooperation of the mounting protrusions 34 and the mounting slots 11, thereby realizing the detachable connection between the outer frame 10 and the bushing body 30. Furthermore, the arrangement of multiple mounting slots 11 and multiple mounting protrusions 34 can improve the connection strength and reliability between the outer frame 10 and the bushing body 30.

[0038] Furthermore, the multiple mounting slots 11 and multiple mounting protrusions 34 can be evenly arranged around the circumference of the elastomer 31. This arrangement ensures that the load is evenly distributed on the elastomer 31 when under stress, helping to prevent local overload, improve the stability and durability of the overall structure, and also help to provide more balanced and stable connection points, thereby improving the connection strength of the entire structure. During the manufacturing process of the multiple mounting slots 11 and multiple mounting protrusions 34, it is easier to ensure that the position and size of each mounting slot 11 and mounting protrusion 34 are accurate. During the assembly process of the outer frame 10 and the bushing body 30, it is also possible to more quickly position and connect the outer frame 10 and the bushing body 30. When it is necessary to adjust the position and angle of the through hole 32 on the elastomer 31, multiple mounting grooves 11 and multiple mounting protrusions 34 are evenly arranged around the circumference of the elastomer 31. By removing the bushing body 30 and rotating the bushing body 30, the through hole 32 can be moved to the preset angle position more quickly and accurately. Then, the adjusted bushing body 30 is installed on the outer frame, which helps to reduce the adjustment time of the position and angle of the through hole 32 and also improves the accuracy of the adjustment. In addition, the mounting grooves 11 and mounting protrusions 34 evenly distributed around the circumference of the elastomer 31 can also enhance the overall aesthetics of the product.

[0039] According to the embodiment of the present invention, the bushing device 100, by forming a through hole 32 in the elastic body 31 of the bushing body 30, can effectively reduce the stiffness of the bushing device 100, improve the vibration isolation performance of the bushing device 100, and also effectively improve the vibration and noise of the whole vehicle, thereby improving the NVH performance of the vehicle. Furthermore, the mounting protrusion 34 can be moved into or out of the corresponding mounting groove 11 along the axial direction of the bushing device 100 to adjust the relative position of the through hole 32 and the outer frame 10. This allows for quick disassembly and assembly of the bushing body 30 and adjustment of the position angle of the through hole 32, thereby adjusting the stiffness of the bushing device 100 to be applied to vehicles with different stiffness requirements. This improves the versatility of the bushing device 100 and helps reduce the development cost of the vehicle.

[0040] According to some embodiments of the present invention, such as Figure 1 As shown, there can be multiple through holes 32, and the multiple through holes 32 are arranged around the inner frame 20 along the circumference of the inner frame 20.

[0041] The through holes 32 can be multiple, for example, there can be two, three, four, or other numbers of through holes 32. However, this utility model is not limited to this, and there can be other numbers of through holes 32, as long as there are multiple through holes 32. Multiple through holes 32 can be arranged around the inner frame 20 in the circumferential direction, which can further reduce the weight of the bushing body 30, thereby effectively reducing the load on the bushing device 100, helping to reduce vehicle energy consumption, improve vehicle handling and acceleration performance, and also avoid stress concentration in the elastomer 31, so as to reduce the risk of damage to the elastomer 31 due to stress concentration. The bushing body 30, the inner frame 20, and the outer frame 10 form a hard and soft integrated limiting, which buffers the damage to the elastomer 31 under large load impact excitation, thereby effectively extending the service life of the bushing device 100.

[0042] According to some embodiments of the present invention, such as Figure 1 As shown, multiple through holes 32 are evenly arranged along the circumference of the inner skeleton 20, which enables the stress of the elastic body 31 to be evenly distributed on the entire elastic body 31 when it is under force, thereby reducing the risk of damage due to excessive local stress of the elastic body 31, and thus effectively extending the fatigue life of the bushing body 30. In addition, the evenly arranged through holes 32 also help to improve the appearance quality of the bushing device 100.

[0043] According to some embodiments of the present invention, such as Figure 1 As shown, there can be two through holes 32, located on opposite sides of the inner frame 20. This arrangement effectively balances and disperses stress, reduces stress concentration, and facilitates airflow and heat dissipation. Especially in high-temperature or high-load working environments, it effectively reduces the temperature of the inner frame 20 and the bushing body 30, lowering the risk of overheating and aging of the bushing assembly 100, thereby improving the stability and durability of the bushing assembly 100. The arrangement of the two through holes 32 on opposite sides of the inner frame 20 also facilitates mold design and manufacturing, improving the machining accuracy of the bushing body 30 and product quality.

[0044] According to some embodiments of the present invention, such as Figure 1 As shown, the through hole 32 can be a strip-shaped hole that extends circumferentially along the inner skeleton 20; and / or the elastomer 31 is adjacent to and fixedly connected to the inner skeleton 20.

[0045] The through-hole 32 can be a strip-shaped hole extending circumferentially along the inner skeleton 20. This strip-shaped hole allows air to flow more smoothly through the elastomer 31, enhancing ventilation and heat dissipation. Furthermore, the circumferential extension of the strip-shaped hole along the inner skeleton 20 ensures more uniform heat dissipation, preventing localized overheating and helping to further extend the service life of the bushing device 100. Additionally, the circumferential extension of the strip-shaped hole along the inner skeleton 20 increases its torsional resistance, improving its stability and durability.

[0046] Alternatively, the elastomer 31 can be adjacent to and fixedly connected to the inner skeleton 20. For example, the elastomer 31 and the inner skeleton 20 can be fixedly connected by adhesive bonding, or by vulcanization molding. However, this utility model is not limited to these methods; the elastomer 31 and the inner skeleton 20 can also be fixedly connected by other means, as long as the elastomer 31 and the inner skeleton 20 are fixedly connected. This application uses the example of the elastomer 31 and the inner skeleton 20 being fixedly connected by vulcanization molding. Under high temperature and pressure, the elastomer 31 undergoes a chemical reaction with the surface of the inner skeleton 20, forming a strong chemical bond. Vulcanization molding has high connection strength, good durability, and wide applicability. It can not only improve the connection strength between the elastomer 31 and the inner skeleton 20 and reduce the risk of loosening or falling off, but it is also suitable for inner skeletons 20 of various shapes and sizes, as well as different types of elastomers 31, thereby reducing the difficulty of connecting the elastomer 31 and the inner skeleton 20.

[0047] Alternatively, the through hole 32 can be a strip-shaped hole extending circumferentially along the inner skeleton 20, with the elastomer 31 adjacent to and fixedly connected to the inner skeleton 20 (this embodiment is used as an example for illustration). This arrangement allows air to flow more smoothly through the elastomer 31, enhancing ventilation and heat dissipation. Furthermore, the strip-shaped hole extending circumferentially along the inner skeleton 20 ensures more uniform heat dissipation, preventing localized overheating and further extending the service life of the bushing device 100. The strip-shaped hole also increases the torsional resistance of the inner skeleton 20, improving its stability and durability. It also strengthens the connection between the elastomer 31 and the inner skeleton 20, reducing the risk of loosening or detachment. This design is suitable for inner skeletons 20 of various shapes and sizes, as well as different types of elastomers 31, thereby reducing the difficulty of connecting the elastomer 31 and the inner skeleton 20.

[0048] According to some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the assembly 33 is annular and is arranged around the elastic body 31 in the circumferential direction.

[0049] The assembly 33 can be annular and arranged around the elastic body 31 in the circumferential direction. The surface of the assembly 33 facing the outer frame 10 has one of a mounting groove 11 and a mounting protrusion 34, and the inner surface of the outer frame 10 has the other of a mounting groove 11 and a mounting protrusion 34. For example, the surface of the assembly 33 facing the outer frame 10 has a mounting groove 11 and the inner surface of the outer frame 10 has a mounting protrusion 34, or the surface of the assembly 33 facing the outer frame 10 has a mounting protrusion 34 and the inner surface of the outer frame 10 has a mounting groove 11. This application uses the example of the surface of the assembly 33 facing the outer frame 10 having a mounting protrusion 34 and the inner surface of the outer frame 10 having a mounting groove 11 for illustration. The mounting groove 11 extends through the bushing device 100 along its axial direction. There can be multiple mounting grooves 11 and mounting protrusions 34, for example, there can be six, eight, ten or other numbers of mounting grooves 11 and mounting protrusions 34. However, this utility model is not limited to this, and there can be other numbers of mounting grooves 11 and mounting protrusions 34, as long as there are multiple mounting grooves 11 and mounting protrusions 34.

[0050] Multiple mounting slots 11 and multiple mounting protrusions 34 are arranged circumferentially along the elastic body 31. The mounting protrusions 34 are assembled into the corresponding mounting slots 11, which can fix the assembly 33 and the outer frame 10 through the cooperation of the mounting protrusions 34 and the mounting slots 11, thereby realizing the detachable connection between the outer frame 10 and the bushing body 30. Furthermore, the arrangement of multiple mounting slots 11 and multiple mounting protrusions 34 can improve the connection strength and reliability between the outer frame 10 and the bushing body 30.

[0051] Furthermore, the multiple mounting slots 11 and multiple mounting protrusions 34 can be evenly arranged around the circumference of the elastomer 31. This arrangement ensures that the load is evenly distributed on the elastomer 31 when under stress, helping to prevent local overload, improve the stability and durability of the overall structure, and also help to provide more balanced and stable connection points, thereby improving the connection strength of the entire structure. During the manufacturing process of the multiple mounting slots 11 and multiple mounting protrusions 34, it is easier to ensure that the position and size of each mounting slot 11 and mounting protrusion 34 are accurate. During the assembly process of the outer frame 10 and the bushing body 30, it is also possible to more quickly position and connect the outer frame 10 and the bushing body 30. When it is necessary to adjust the position and angle of the through hole 32 on the elastomer 31, multiple mounting grooves 11 and multiple mounting protrusions 34 are evenly arranged around the circumference of the elastomer 31. By removing the bushing body 30 and rotating the bushing body 30, the through hole 32 can be moved to the preset angle position more quickly and accurately. Then, the adjusted bushing body 30 is installed on the outer frame, which helps to reduce the adjustment time of the position and angle of the through hole 32 and also improves the accuracy of the adjustment. In addition, the mounting grooves 11 and mounting protrusions 34 evenly distributed around the circumference of the elastomer 31 can also enhance the overall aesthetics of the product.

[0052] According to some embodiments of the present invention, such as Figure 1 As shown, multiple mounting slots 11 and multiple mounting protrusions 34 can be evenly arranged circumferentially along the elastic body 31, ensuring the uniformity and stability of the bushing device 100. Furthermore, the multiple mounting slots 11 and multiple mounting protrusions 34 correspond one-to-one, ensuring that during the assembly of the outer frame 10 and the assembly body 33, the mounting protrusions 34 can be fitted into the corresponding mounting slots 11, thereby achieving a firm connection between the outer frame 10 and the assembly body 33, and thus improving the stability and reliability of the bushing device 100. Simultaneously, it also ensures that the elastic body 31 can evenly distribute the load when under stress, helping to prevent local overload, improve the stability and durability of the overall structure, and also helps to provide more balanced and stable connection points, thereby improving the connection strength of the entire structure. During the manufacturing process of the multiple mounting slots 11 and multiple mounting protrusions 34, it is easier to ensure that the position and size of each mounting slot 11 and mounting protrusion 34 are accurate. During the assembly of the outer frame 10 and the bushing body 30, it is also possible to more quickly and accurately position and connect the outer frame 10 and the bushing body 30. In addition, the mounting grooves 11 and mounting protrusions 34, which are evenly distributed along the circumference of the elastomer 31, can enhance the overall aesthetics of the product.

[0053] Furthermore, during the design phase of the bushing device 100, the position and angle of the through hole 32 on the elastomer 31 can be quickly adjusted for vehicle matching, determining the optimal angle of the through hole 32 position to meet the needs of vehicles with different stiffness requirements, thus achieving the universality of the bushing device 100. During the mass production phase of the bushing device 100, marking points can be drawn on the outer frame 10 and inner frame 20 to accurately control the position and angle of the through hole 32 before assembling the outer frame 10 with the bushing body 30, ensuring consistent product performance.

[0054] When the position and angle of the through hole 32 on the elastic body 31 need to be adjusted after the outer frame 10 and the bushing body 30 are assembled, the marking points of the angle to be adjusted can be drawn on the outer frame 10 and the inner frame 20 first. Then, the bushing body 30 is taken out from the outer frame 10 along the axial direction of the bushing body 30. The bushing body 30 is rotated to the corresponding marking point and then assembled into the outer frame 10 to realize the adjustment of the position and angle of the through hole 32, thereby realizing the adjustment of the stiffness of the bushing device 100.

[0055] Furthermore, when marking, the markings on the outer frame 10 and the inner frame 20 are located in different positions, and the included angle between the outer frame 10 and the inner frame 20 is the angle that needs to be adjusted. After removing the bushing body 30 from the outer frame 10 along the axial direction of the bushing body 30, the bushing body 30 is rotated so that the markings on the outer frame 10 and the inner frame 20 are in the same position. Then the bushing body 30 is assembled into the outer frame 10, thereby realizing the adjustment of the position and angle of the through hole 32, and thus realizing the adjustment of the stiffness of the bushing device 100.

[0056] When adjusting the position and angle of the through hole 32 on the elastic body 31, the multiple mounting grooves 11 and multiple mounting protrusions 34 can be evenly arranged around the circumference of the elastic body 31. This allows the through hole 32 to reach the preset angle position more quickly and accurately when the bushing body 30 is rotated. This avoids the phenomenon of rotation error of the bushing body 30 caused by uneven distribution of the multiple mounting grooves 11 and multiple mounting protrusions 34, thus avoiding the phenomenon of incorrect adjustment of the position and angle of the through hole 32. This improves the reliability and safety of the bushing device 100.

[0057] In the later stages, when the bushing body 30 is damaged or reaches the end of its service life, the bushing body 30 can be quickly replaced without replacing the entire bushing device 100, which significantly shortens the maintenance time, reduces maintenance costs, and improves the maintainability of the bushing device 100.

[0058] The suspension system according to the present invention includes the bushing device 100 of the above embodiment. It can effectively reduce the stiffness of the bushing device 100, improve the vibration isolation performance of the bushing device 100, and effectively improve the vibration and noise of the whole vehicle, thereby improving the vibration isolation performance of the suspension system and thus improving the NVH performance of the vehicle.
