Description

Technical Field

[0001] This utility model relates to the field of vehicle suspension technology, and particularly to a suspension assembly. Furthermore, this utility model also relates to a vehicle equipped with the aforementioned suspension assembly. Background Technology

[0002] Currently, in automotive design, as people's requirements for ride comfort continue to increase, reducing in-vehicle vibration and noise has become an important goal. As the main source of vibration, the engine's vibration needs to be effectively isolated through the suspension system.

[0003] Furthermore, vehicle engines experience diverse vibration frequencies and amplitudes under various operating conditions, such as starting, idling, acceleration, and high-speed driving. In traditional suspension assemblies, the rubber is typically vulcanized in one piece, thus limiting the range of stiffness and making it difficult to achieve good vibration isolation across a wide frequency range. This also prevents the simultaneous consideration of production costs and the flexibility of suspension assembly applications, making it unsuitable for various vehicle models. Utility Model Content

[0004] In view of this, the present invention aims to provide a suspension assembly to facilitate the application of the lifting device.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A suspension assembly comprising a suspension having a sleeve, an inner core, and a rubber main spring;

[0007] The sleeve is annular and is formed by splicing together multiple fan-shaped branch pipes, with vibration damping rubber sandwiched at the connection points of adjacent branch pipes; the inner core is located inside the sleeve; the rubber main spring is vulcanized and connected between the inner core and at least one of the branch pipes.

[0008] Furthermore, each of the branch pipes has an inwardly bent section at its end, and the vibration damping rubber between adjacent branch pipes is located between adjacent bent sections.

[0009] Furthermore, the suspension assembly also includes a suspension bracket with a suspension mounting hole, the suspension being inserted into the suspension mounting hole; the sleeve is provided with an anti-detachment structure, the anti-detachment structure being used to prevent the suspension from detaching from the suspension bracket along the axial direction of the suspension mounting hole.

[0010] Furthermore, each of the branch tubes is provided with an anti-detachment structure, each of the anti-detachment structures including a flange at the first end of the branch tube and a clamp at the second end of the branch tube, and both sides of the clamp are provided with notches extending to the second end.

[0011] Furthermore, each of the branch pipes has a guide portion at its second end, which is used to guide the sleeve into the suspension mounting hole.

[0012] Furthermore, the plurality of the branch pipes include an upper branch pipe and a lower branch pipe arranged in a vertical direction, and the rubber main spring is vulcanized and connected between the inner core and the lower branch pipe.

[0013] Furthermore, the rubber main spring includes an inner core connecting part and a support connecting part; the inner core connecting part covers the outer part of the inner core, the upper part of the support connecting part is integrally connected to the inner core connecting part, and the lower part of the support connecting part is connected to the lower branch pipe.

[0014] Furthermore, at least one of the branch tubes is provided with a limiting rubber, which is used to limit the extreme position of the inner core's radial movement along the sleeve.

[0015] Furthermore, the limiting rubber includes a first limiting rubber, a second limiting rubber, and a third limiting rubber; the first limiting rubber is disposed on the upper branch pipe, and the upper part of the inner core connecting part is in contact with the first limiting rubber.

[0016] The second limiting rubber is provided on the upper branch pipe or the lower branch pipe, and the second limiting rubber is provided on both sides of the inner core. A first gap is provided between the inner core connecting part and each of the second limiting rubbers. A notch is provided at the lower part of the supporting connecting part, and the third limiting rubber is located in the notch and a second gap is provided between it and the supporting connecting part.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] The suspension assembly described in this utility model features vibration-damping rubber at the connection points of adjacent branch pipes. This provides better support for the branch pipes, ensuring the stability and reliability of the sleeve after installation on the suspension bracket. It also works in conjunction with the rubber main spring to improve the vibration damping performance of the suspension assembly. The inner core, located inside the sleeve, facilitates connection to the powertrain and serves as the connection base for the rubber main spring. The rubber main spring provides the necessary elasticity and damping performance to cope with the load and vibration borne by the suspension assembly. By disassembling the sleeve into multiple branch pipes, the design of splicing these pipes allows for more flexible and convenient manufacturing and assembly of the suspension assembly. For example, different rubbers can be vulcanized on each branch pipe, and different branch pipes can be assembled to form suspension assemblies with different performance characteristics, thus increasing the applicability of the suspension assembly and reducing processing costs.

[0019] Secondly, each branch pipe has an inwardly bent section at its end, and the vibration damping rubber between adjacent branch pipes is located between adjacent bent sections, which helps to increase the arrangement space of the vibration damping rubber and improve the supporting effect of the vibration damping rubber on the branch pipe. This structure also helps to enhance the connection strength between branch pipes, while ensuring the stability and reliability of the entire sleeve structure.

[0020] Incorporating an anti-detachment structure between the suspension mount and its bracket enhances the stability of the suspension mount during installation. This structure ensures the mount remains in the correct position when subjected to external forces or vibrations, preventing unnecessary detachment or loosening. This improves the stability and reliability of the suspension assembly and also contributes to enhancing the overall shock absorption and vibration isolation performance of the suspension system.

[0021] Furthermore, the combination of the flange and the clamp provides an effective anti-detachment structure for the branch pipes. The flange prevents the branch pipe from falling off from the first end, while the clamp and notch, in conjunction with the mounting hole, allow the clamped portion to bend inward along the radial direction of the suspension during installation. After passing through the mounting hole, the clamped portion returns to its original position, allowing it to abut against the end of the mounting hole, thus preventing the branch pipe from falling off from the second end and enhancing the stability and reliability of the entire suspension assembly. Each branch pipe's second end is designed with a guide section, making it easier and more accurate to insert the sleeve into the mounting hole. This design improves the efficiency and accuracy of the suspension installation process.

[0022] Furthermore, the multiple pipes are not only spliced ​​together in the circumferential direction to form a sleeve, but also differentiated in the vertical direction, specifically divided into upper pipes and lower pipes. This helps to better distribute and bear the load and vibration from different directions, improving the overall performance and stability of the suspension assembly. The rubber main spring is connected between the inner core and the lower pipe through the vulcanization process, so that the rubber main spring mainly bears the vibration from the vertical direction, which can effectively reduce vibration and isolate vibration.

[0023] The inner core connecting part is the part of the rubber main spring that covers the outside of the inner core. It ensures a tight connection between the rubber main spring and the inner core. The main function of the supporting connecting part is to connect the rubber main spring and the lower branch tube. In this way, the rubber main spring can better attenuate vibrations in the vertical direction, so that the suspension assembly has good shock absorption and vibration isolation performance. When applied to vehicles, it helps to improve the overall ride comfort.

[0024] Limiting rubber is installed on each branch pipe. When the inner core is subjected to external force or vibration and attempts to move radially inside the sleeve, the limiting rubber provides a physical barrier, effectively and reliably preventing excessive movement of the inner core. At the same time, the limiting rubber also provides additional shock absorption and vibration isolation functions, further enhancing the overall performance of the mounting assembly.

[0025] A first limiting rubber is installed on the upper branch pipe to effectively restrict the upper limit position of the inner core, thereby improving the vibration damping and isolation performance of the suspension assembly in the vertical direction of the vehicle. A second limiting rubber is installed on either the upper or lower branch pipe to effectively restrict the movement limit position of the inner core in the longitudinal direction of the vehicle, thereby improving the vibration damping and isolation performance of the suspension assembly in the longitudinal direction of the vehicle. The second limiting rubber, in conjunction with the first limiting rubber, can improve the vibration damping and isolation performance of the suspension assembly in multiple directions of the vehicle.

[0026] A notch is provided at the lower part of the support connection to accommodate the third limiting rubber, which can better limit the lower extreme position of the inner core. The second gap allows the support connection to have a certain elastic deformation when subjected to vibration or load, while still being limited by the third limiting rubber. The third limiting rubber works in conjunction with the aforementioned first and second limiting rubbers to make the shock absorption and vibration isolation performance of the suspension assembly even better.

[0027] Another objective of this invention is to provide a vehicle having the suspension assembly described above.

[0028] The vehicle described in this utility model has the same beneficial effects as the aforementioned suspension assembly compared to the prior art, and will not be described again here. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0047] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] Example 1

[0049] This embodiment relates to a suspension assembly. By improving its structure, it is easy to form suspension assemblies with different performance, thereby increasing the applicability of the suspension assembly.

[0050] In terms of overall structure, combined Figures 1 to 4As shown, the suspension assembly of this embodiment includes a suspension 1 having a sleeve 2, an inner core 3 and a rubber main spring 4. The sleeve 2 is annular and is formed by splicing together multiple branch pipes in a fan-shaped annular shape. The connection parts of adjacent branch pipes are sandwiched with vibration damping rubber 23.

[0051] At this time, the suspension assembly described in this utility model has vibration damping rubber 23 at the connection part of the adjacent branch pipe, which can better support the branch pipe, which helps to ensure the stability and reliability of the sleeve 2 after it is installed on the suspension bracket 5. It can also cooperate with the rubber main spring 4 to improve the vibration damping performance of the suspension assembly.

[0052] By splitting the sleeve 2 into multiple sub-tubes, the design of splicing the sub-tubes may make the manufacturing and assembly of the suspension assembly more flexible and convenient. For example, different rubbers can be vulcanized on each sub-tube, and suspension assemblies with different properties can be formed by assembling different sub-tubes, which can improve the applicability of the suspension assembly and help reduce processing costs.

[0053] Meanwhile, in this embodiment, the inner core 3 is located inside the sleeve 2, and the rubber main spring 4 is vulcanized and connected between the inner core 3 and at least one of the branch pipes. Here, placing the inner core 3 inside the sleeve 2 facilitates connection to the powertrain and serves as the connection base for the rubber main spring 4. The function of the rubber main spring 4 is to provide the necessary elasticity and damping performance to cope with the load and vibration borne by the suspension assembly.

[0054] It is worth mentioning that the inner core 3 of this embodiment has a connecting hole 31 in the middle, which can cooperate with the support arm 9. In specific implementation, one end of the support arm 9 can be inserted into the connecting hole 31, and the other end can be connected to the suspension assembly. At the same time, the vibration damping rubber 23 and the branch pipe can be connected by vulcanization. Of course, in addition to vulcanization, other common connection methods can also be used, such as bonding.

[0055] Based on the above overall introduction, in this embodiment, as a preferred implementation, such as Figure 2 and Figure 3 As shown, each branch pipe has an inwardly bent section 24 at its end, and the vibration damping rubber 23 between adjacent branch pipes is located between adjacent bent sections 24.

[0056] The advantage of this arrangement is that it allows for more space to be allocated for the damping rubber 23, which can improve the supporting effect of the damping rubber 23 on the branch pipes. This structure also helps to enhance the connection strength between the branch pipes, while ensuring the stability and reliability of the entire sleeve 2 structure.

[0057] It should be noted that the bent section 24 in this embodiment can be inserted into the first gap 81 mentioned below, which facilitates increasing the connection area of ​​adjacent branch pipes, improves the structural reliability of the sleeve 2 formed by splicing, and can also prevent the branch pipe from detaching from the suspension bracket 5 along the axial direction of the suspension mounting hole.

[0058] It should be understood that in other embodiments, the ends of each branch pipe may not be provided with a bend 24, in which case vibration damping rubber 23 is provided between the ends of adjacent branch pipes.

[0059] Furthermore, in this embodiment, as a preferred implementation, such as Figure 1 As shown, the suspension assembly also includes a suspension bracket 5 with a suspension mounting hole, into which the suspension 1 is inserted. This improves the stability of the suspension 1 when mounted on the suspension bracket 5.

[0060] Meanwhile, the sleeve 2 is provided with an anti-detachment structure 6, which is used to prevent the suspension 1 from detaching from the suspension bracket 5 along the axial direction of the suspension mounting hole. The anti-detachment structure 6 ensures that the suspension 1 remains in the correct position when it is subjected to external force or vibration, avoiding unnecessary detachment or loosening, which can enhance the stability and reliability of the suspension assembly, and also help improve the shock absorption and vibration isolation performance of the entire suspension system.

[0061] In detail, the anti-detachment structure 6 includes flanges 61 and clamps 62 located at both ends of the sleeve 2. Specifically, each branch pipe is provided with flanges 61 that bend outward along the radial direction of the sleeve 2. Relative to the end with flanges 61, the other end of the branch pipe is provided with clamps 62. The clamps 62 are wedge-shaped, and notches 63 are provided on both sides of the sleeve 2 along the circumference at the location where the clamps 62 are provided.

[0062] When the suspension 1 is inserted into the suspension mounting hole, the part with the clamp 62 can deform inward along the radial direction of the sleeve 2, and after passing through the suspension mounting hole, the part with the clamp 62 returns to its original position, so that the clamp 62 abuts against the end wall of the suspension mounting hole, thereby preventing the suspension 1 from detaching from the suspension bracket 5 along the axial direction of the suspension mounting hole.

[0063] Furthermore, the suspension bracket 5 in this embodiment specifically includes a bracket body 51 and an outer tube 52 disposed on the bracket body 51. The outer tube 52 is cylindrical and has the aforementioned suspension mounting hole. In specific implementation, the bracket body 51 is connected to the vehicle frame through the mounting hole 511 thereon.

[0064] Specifically, in this embodiment, as a preferred implementation, such as Figure 4 As shown, each branch pipe is provided with an anti-detachment structure 6. Each anti-detachment structure 6 includes a flange 61 at the first end of the branch pipe and a clamp 62 at the second end of the branch pipe. Both sides of the clamp 62 are provided with notches 63 extending to the second end.

[0065] Here, the combination of flange 61 and clamp 62 provides an effective anti-detachment structure 6 for the branch pipe. Flanged flange 61 can prevent the branch pipe from falling off from the first end, while clamp 62 and notch 63 cooperate. During the installation of the suspension 1 into the suspension mounting hole, the part with clamp 62 can bend and deform radially inward along the suspension 1. After passing through the suspension mounting hole, the part with clamp 62 returns to its original position, so that clamp 62 abuts against the end of the suspension mounting hole, thereby preventing the branch pipe from falling off from the second end and enhancing the stability and reliability of the entire suspension assembly.

[0066] Meanwhile, as a preferred implementation form, such as Figure 4 As shown in the figure, each of the second ends of the branch pipes in this embodiment is provided with a guide portion 25, which is used to guide the sleeve 2 to be inserted into the suspension mounting hole.

[0067] Here, a guide portion 25 is designed at the second end of each branch pipe, making it easier and more accurate to insert the sleeve 2 into the suspension mounting hole. This design improves the efficiency and accuracy of the suspension 1 installation process. Furthermore, in this embodiment, the guide portion 25 can be a chamfered right angle at the second end of the branch pipe. It should be understood that a rounded corner for the guide portion 25 is also feasible.

[0068] It should be noted that, in terms of specific structure, the guide part 25 at the second end of each branch pipe can be provided on the clamp head 62 or at the part of the second end without the clamp head 62.

[0069] Furthermore, in this embodiment, as a preferred implementation, reference is still made to... Figure 4 As shown, the multiple pipes include an upper pipe 21 and a lower pipe 22 arranged in the vertical direction, and a rubber main spring 4 is vulcanized and connected between the inner core 3 and the lower pipe 22. When applied to a vehicle, the upper pipe 21 and the lower pipe 22 are arranged vertically along the entire vehicle.

[0070] This design allows multiple branch pipes to not only be spliced ​​together circumferentially to form sleeve 2, but also to be differentiated in the vertical direction of the vehicle, specifically divided into upper branch pipe 21 and lower branch pipe 22. This helps to better distribute and bear the load and vibration from different directions, improving the overall performance and stability of the suspension assembly. The rubber main spring 4 is connected between the inner core 3 and the lower branch pipe 22 through a vulcanization process, so that the rubber main spring 4 mainly bears the vibration from the vertical direction, which can effectively reduce vibration and isolate shock.

[0071] In one preferred embodiment, the rubber main spring 4 includes an inner core connecting part 41 and a support connecting part 42. The inner core connecting part 41 covers the inner core 3, the upper part of the support connecting part 42 is connected to the inner core connecting part 41 as a whole, and the lower part of the support connecting part 42 is connected to the lower branch pipe 22.

[0072] Understandably, the inner core connecting part 41 is the part of the rubber main spring 4 that covers the outside of the inner core 3. It can ensure a tight connection between the rubber main spring 4 and the inner core 3. The main function of the supporting connecting part 42 is to connect the rubber main spring 4 and the lower branch tube 22. In this way, the rubber main spring 4 can better attenuate the vibration in the vertical direction, so that the suspension assembly has good shock absorption and vibration isolation performance. When applied to vehicles, it helps to improve the overall vehicle ride comfort.

[0073] Furthermore, in this embodiment, as a preferred implementation, refer to... Figure 2 As shown, at least one of the tubes is provided with a limiting rubber 7, which is used to limit the extreme position of the inner core 3 moving radially along the sleeve 2.

[0074] Therefore, limiting rubber 7 is installed on each branch pipe. When the inner core 3 is subjected to external force or vibration and attempts to move radially inside the sleeve 2, the limiting rubber 7 provides a physical barrier, effectively and reliably preventing the inner core 3 from moving too much. At the same time, the limiting rubber 7 can also provide additional shock absorption and vibration isolation functions, further enhancing the overall performance of the mounting assembly.

[0075] In addition, as a preferred implementation method, refer to Figure 2 As shown, the limiting rubber 7 in this embodiment includes a first limiting rubber 71, a second limiting rubber 72, and a third limiting rubber 73. The first limiting rubber 71 is disposed on the upper branch pipe 21, and the upper part of the inner core connecting part 41 is in contact with the first limiting rubber 71. Therefore, by providing the first limiting rubber 71 on the upper branch pipe 21, the upper limit position of the inner core 3 can be effectively limited, which is beneficial to improving the shock absorption and vibration isolation performance of the suspension assembly in the vertical direction of the vehicle.

[0076] Meanwhile, the second limiting rubber 72 is provided on the upper branch pipe 21 or the lower branch pipe 22, and the second limiting rubber 72 is provided on both sides of the inner core 3, and the first gap 81 is provided between the inner core connecting part 41 and each of the second limiting rubbers 72.

[0077] Here, a second limiting rubber 72 is installed on the upper branch pipe 21 or the lower branch pipe 22, which can effectively limit the movement limit of the inner core 3 in the longitudinal direction of the vehicle, thereby improving the shock absorption and vibration isolation performance of the suspension assembly in the longitudinal direction of the vehicle. The second limiting rubber 72 works in conjunction with the first limiting rubber 71 to improve the shock absorption and vibration isolation performance of the suspension assembly in multiple directions of the vehicle.

[0078] The lower part of the support connection 42 is provided with a notch 731, and the third limiting rubber 73 is located within the notch 731, with a second gap 82 between it and the support connection 42. This design can effectively limit the lower extreme position of the inner core 3. The second gap 82 allows the support connection 42 to have a certain degree of elastic deformation when subjected to vibration or load, while still being limited by the third limiting rubber 73. The third limiting rubber 73 works in conjunction with the aforementioned first limiting rubber 71 and second limiting rubber 72, resulting in superior shock absorption and vibration isolation performance of the suspension assembly.

[0079] It should be noted that, in the preferred embodiment, the stiffness of the limiting rubber 7 is different from that of the rubber main spring 4, and it is better for the stiffness of the limiting rubber 7 to be greater than that of the rubber main spring 4, so as to achieve a better limiting effect. It should be understood that it is also feasible for the stiffness of the limiting rubber 7 to be less than or equal to the stiffness of the rubber main spring 4.

[0080] For ease of processing, in this embodiment, the first limiting rubber 71 and the second limiting rubber 72 have the same stiffness, which is relatively high, and are vulcanized together and connected to the upper branch pipe 21. The third limiting rubber 73 and the rubber main spring 4 have the same stiffness, which is relatively low compared to the first limiting rubber 71 and the second limiting rubber 72, and are vulcanized together and connected to the lower branch pipe 21.

[0081] In other embodiments, the stiffness of the first limiting rubber 71, the second limiting rubber 72, and the third limiting rubber 73 can be set according to requirements. The stiffness of the three can be the same, or the stiffness of the three can be different, or two of the three can have the same stiffness.

[0082] In the specific structure, the second limiting rubber 72 is disposed on the upper branch pipe 21, and the joint point between the upper branch pipe 21 and the lower branch pipe 22 is located between the second limiting rubber 72 and the rubber main spring 4, that is, at the lower end of the first gap 81. In other embodiments, it is also feasible to dispose of the second limiting rubber 72 on the lower branch pipe 22. In this case, the joint point between the upper branch pipe 21 and the lower branch pipe 22 is located between the second limiting rubber 72 and the first limiting rubber 71, that is, at the upper end of the first gap 81.

[0083] It should be noted that the vibration damping rubber 23 in this embodiment has multiple states, thereby enabling it to support the upper branch pipe 21 and the lower branch pipe 22 in different scenarios. Specifically, before the upper branch pipe 21 and the lower branch pipe 22 are pressed into the suspension mounting hole, the vibration damping rubber 23 is not compressed, its thickness reaches its maximum, and the rubber main spring 4 is in its natural state.

[0084] Secondly, when the upper branch pipe 21 and the lower branch pipe 22 are press-fitted into the suspension mounting hole, the vibration damping rubber 23 is compressed to its limit, at which point its thickness is minimized, thus facilitating the press-fitting of the upper branch pipe 21 and the lower branch pipe 22 into the suspension mounting hole. At this time, the first limiting rubber 71 squeezes the upper part of the inner core connecting part 41, thereby causing the connecting hole 31 to move downward relative to the lower part of the supporting connecting part 42, so that the supporting connecting part 42 is in a downward compressed state.

[0085] Furthermore, after the upper branch pipe 21 and the lower branch pipe 22 are pressed into the suspension mounting hole, the vibration damping rubber 23 returns to its intermediate compressed state. At this time, its thickness is at the intermediate thickness, which can simultaneously provide extrusion force to the upper branch pipe 21 and the lower branch pipe 22 to fix them. Also, the upper part of the inner core connecting part 41 is in contact with the first limiting rubber 71, and there is compression deformation.

[0086] After the suspension assembly is installed, the support arm 9 is pressed down under the weight of the powertrain, and the support connection part 42 is in a compressed state. The upper part of the inner core connection part 41 is no longer in contact with the first limiting rubber 71, which leads to an increase in the gap between the upper part of the inner core connection part 41 and the first limiting rubber 71. The gap at this time is usually between 0 and 4 mm, such as 1 mm, 2 mm, or 3 mm.

[0087] In a preferred embodiment, the shape of the aforementioned first gap 81 changes with the upper shape of the rubber main spring 4. Specifically, a first gap 81 is provided between the inner core connecting part 41 and the second limiting rubber 72 in the front-rear direction of the whole vehicle. The upper part of the first gap 81 extends in the vertical direction, and the lower part of the first gap 81 extends downward while tilting away from the inner core 3, which facilitates the arrangement of the bending section 24 and the vibration damping rubber 23.

[0088] In addition, in specific implementation, the second gap 82 in this embodiment can be set as an inverted U-shape, which has a good limiting effect in both the vertical and longitudinal directions of the vehicle.

[0089] In this embodiment, the suspension assembly is disassembled into an upper branch pipe 21 and a lower branch pipe 22. Different types of rubber can be vulcanized on each branch pipe, and different branch pipes can be assembled to form suspension assemblies with different performance characteristics, thereby improving the applicability of the suspension assembly. Vibration-damping rubber 23 is provided at the connection between the upper branch pipe 21 and the lower branch pipe 22, which can better support the upper branch pipe 21 and the lower branch pipe 22, thus ensuring the stability and reliability of the sleeve 2 after it is installed on the suspension bracket 5.

[0090] Example 2

[0091] This embodiment relates to a vehicle that is equipped with the suspension assembly described in Embodiment 1.

[0092] The vehicle in this embodiment, by adopting the suspension assembly in Embodiment 1, can ensure the stability and reliability of the sleeve 2 after it is installed on the suspension bracket 5. By cooperating with the rubber main spring 4, the vibration damping performance of the suspension assembly can be improved. Furthermore, the design of using separate pipe splicing may make the manufacturing and assembly of the suspension assembly more flexible and convenient, thereby improving the applicability of the suspension assembly and reducing processing costs.

[0093] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
