Description

Technical Field

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

[0002] With the continuous development of society, vehicles have become an indispensable part of people's lives as a means of transportation. When vehicles drive on uneven roads, or encounter emergencies requiring sudden braking, acceleration, or collisions, the vehicle body will shake, and the shock absorption device will also shake accordingly. These vibrations and shaking seriously affect the driving and riding experience of passengers. To address this, people have developed suspension structures that can be used for vibration isolation.

[0003] Traditional suspension structures typically use a rubber vulcanization process to connect the inner core and outer support into one unit. This process can only generate the required stiffness in specific directions and areas of the rubber, which limits the applicability of the suspension. In addition, the suspension needs to be manufactured using specialized molds. Due to its integrated structure, the molds are highly complex, which increases the processing cost. Utility Model Content

[0004] In view of this, the present invention aims to provide a suspension sleeve to improve the applicability of the suspension assembly and reduce processing costs.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A suspension sleeve is used for insertion into a suspension mounting hole of a suspension bracket; the suspension sleeve is annular and includes a plurality of fan-shaped branch tubes, which are spliced ​​together to form the suspension sleeve; the interior of the suspension sleeve is used to accommodate an inner core and a rubber main spring connecting the inner core and at least one of the branch tubes.

[0007] Furthermore, the plurality of the branch pipes include an upper branch pipe, a middle branch pipe, and a lower branch pipe. Both ends of the upper branch pipe and the lower branch pipe are connected through the middle branch pipe, and the upper branch pipe, the middle branch pipe, and the lower branch pipe are arranged sequentially in the vertical direction. Both ends of the middle branch pipe are used to connect to the rubber main spring.

[0008] Furthermore, the suspension sleeve is provided with an anti-detachment structure, which is used to prevent the suspension sleeve from detaching from the suspension bracket along the axial direction of the suspension mounting hole.

[0009] Furthermore, each of the branch pipes is provided with an anti-detachment structure, each of the anti-detachment structures including a flange at the first end of the branch pipe and a clamp at the second end of the branch pipe, and both sides of the clamp are provided with notches extending to the second end.

[0010] Furthermore, each of the second ends of the branch pipes is provided with a guide portion, which is used to guide the suspension sleeve into the suspension mounting hole.

[0011] Furthermore, each of the branch pipes has an inwardly bent section at its end, and adjacent branch pipes are connected by the adjacent bent sections.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] The suspension sleeve described in this utility model, by splitting the suspension sleeve into multiple sub-tubes and splicing the sub-tubes, makes the manufacturing and assembly of the suspension assembly more flexible and convenient. For example, different stiffness rubbers can be vulcanized on each sub-tube, and by assembling different sub-tubes, suspension assemblies with different performance can be formed, which can improve the applicability of the suspension assembly and help reduce processing costs.

[0014] Secondly, the multiple pipes are not only spliced ​​together in the circumferential direction to form the suspension sleeve, but are also specifically divided into upper pipes, middle pipes and lower pipes, which can be distinguished in the vertical direction of the whole vehicle. This helps to better distribute and bear the load and vibration from different directions, and improve the overall performance and stability of the suspension assembly. The rubber main spring is connected between the inner core and the middle pipe through the vulcanization process, so that the rubber main spring can better bear the vibration from the vertical direction, and can better perform shock absorption and vibration isolation.

[0015] Incorporating an anti-detachment structure on the suspension sleeve improves the stability of the suspension sleeve during installation on the suspension bracket. This anti-detachment structure ensures the suspension remains in the correct position when subjected to external forces or vibrations, preventing unnecessary detachment or loosening. This enhances the stability and reliability of the suspension assembly and also helps improve the shock absorption and vibration isolation performance of the entire suspension system.

[0016] 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 suspension sleeve into the mounting hole. This design improves the efficiency and accuracy of the suspension installation process.

[0017] Furthermore, each branch pipe has an inwardly bent section at its end, and vibration damping rubber between adjacent branch pipes is placed between adjacent bent sections, which helps to increase the contact area at the branch pipe connection. This structure helps to enhance the connection strength between branch pipes, while ensuring the stability and reliability of the entire suspension sleeve structure.

[0018] In addition, another objective of this utility model is to provide a suspension assembly, which includes a suspension bracket having a suspension mounting hole and a suspension inserted into the suspension mounting hole; the suspension includes the suspension sleeve as described above, and also includes an inner core and a rubber main spring, the rubber main spring being connected between the center tube and the inner core.

[0019] Furthermore, the rubber main spring includes an inner core connecting part and a support connecting part;

[0020] The inner core connecting part covers the outer part of the inner core, the upper part of the supporting connecting part is connected to the inner core connecting part as a whole, and the lower part of the supporting connecting part is connected to the middle tube.

[0021] Furthermore, both the upper and lower branch pipes are provided with limiting rubber, which is used to limit the extreme position of the inner core's radial movement along the suspension sleeve; the limiting rubber and the rubber main spring have different stiffnesses.

[0022] The inner core, located inside the suspension sleeve, facilitates connection to the powertrain and serves as the base for the rubber main spring. The rubber main spring provides the necessary elasticity and damping performance to withstand the loads and vibrations experienced by the suspension assembly.

[0023] The inner core connecting part is the part of the rubber main spring that covers the outer part 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 center 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] Meanwhile, limiting rubber is installed on both the upper and lower branch pipes. When the inner core is subjected to external force or vibration and attempts to move radially inside the suspension sleeve, the limiting rubber provides a physical barrier, effectively and reliably preventing excessive movement of the inner core. Furthermore, the limiting rubber also provides additional shock absorption and vibration isolation functions, further enhancing the overall performance of the suspension assembly.

[0025] Furthermore, another object of this utility model is to provide a vehicle having the suspension assembly described above.

[0026] 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.

[0044] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] Example 1

[0046] This embodiment relates to a suspension sleeve to improve the applicability of the suspension assembly and reduce processing costs.

[0047] In terms of overall structure, combined Figures 1 to 4 As shown, the suspension sleeve of this embodiment is used to be inserted into the suspension mounting hole of the suspension bracket 6. The suspension sleeve is annular and includes multiple branch tubes in a fan-shaped annular shape. The multiple branch tubes can be spliced ​​together to form the suspension sleeve. The interior of the suspension sleeve is used to accommodate the inner core 1 and the rubber main spring 3 connecting the inner core 1 and at least one of its branch tubes.

[0048] At this point, with the above configuration, by splitting the suspension sleeve into multiple sub-tubes, the design of splicing the sub-tubes can 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 by assembling different sub-tubes, suspension assemblies with different performance can be formed, which can improve the applicability of the suspension assembly and help reduce processing costs.

[0049] It should be noted that the suspension sleeve in this embodiment can be divided into two sub-tubes, and adjacent sub-tubes can be connected by welding. Of course, in addition to welding, other common connection methods can also be used, such as screw connection, snap connection, etc.

[0050] Based on the above overall introduction, in this embodiment, as a preferred implementation, such as Figure 1As shown, the multiple pipes include an upper pipe 21, a middle pipe 22, and a lower pipe 23. Both ends of the upper pipe 21 and the lower pipe 23 are connected via the middle pipe 22. The upper pipe 21, middle pipe 22, and lower pipe 23 are arranged sequentially in the vertical direction, and both ends of the middle pipe 22 are used to connect to the rubber main spring 3. When applied to a vehicle, the upper pipe 21, middle pipe 22, and lower pipe 23 are arranged sequentially from top to bottom along the vertical direction of the entire vehicle.

[0051] Here, multiple pipes are not only spliced ​​together in the circumferential direction to form a suspension sleeve, specifically divided into upper pipe 21, middle pipe 22 and lower pipe 23, but also differentiated in the vertical direction of the whole vehicle. This helps to better distribute and bear the load and vibration from different directions, improve the overall performance and stability of the suspension assembly, and the rubber main spring 3 is connected between the inner core 1 and the middle pipe 22 through the vulcanization process, so that the rubber main spring 3 can better bear the vibration from the vertical direction and can better perform shock absorption and vibration isolation.

[0052] It should be understood that in other embodiments, the upper branch pipe 21 can be combined with the middle branch pipe 22 as one unit, or the lower branch pipe 23 can be combined with the middle branch pipe 22 as one unit, thereby simplifying the structure and facilitating design and implementation.

[0053] Furthermore, in this embodiment, as a preferred implementation, such as Figure 2 As shown, the suspension sleeve is provided with an anti-detachment structure 4, which is used to prevent the suspension sleeve from detaching from the suspension bracket 6 along the axial direction of the suspension mounting hole.

[0054] Therefore, by setting the anti-detachment structure 4 on the suspension sleeve, the stability of the suspension sleeve installed on the suspension bracket 6 is improved. It also ensures that the suspension remains in the correct position when subjected to external forces or vibrations, preventing unnecessary detachment or loosening. This enhances the stability and reliability of the suspension assembly and also helps improve the shock absorption and vibration isolation performance of the entire suspension system.

[0055] It should be noted that the anti-detachment structure 4 specifically includes flanges 41 and clamps 42 located at both ends of the suspension sleeve. In the specific structure, each branch pipe is provided with flanges 41 that bend outward along the radial direction of the suspension sleeve. Relative to the end with flanges 41, the other end of the branch pipe is provided with wedge-shaped clamps 42. At the location where clamps 42 are provided, notches 43 are provided on both sides along the circumference of the suspension sleeve.

[0056] When the suspension is inserted into the suspension mounting hole, the portion with the clamp 42 can deform radially inward along the suspension sleeve, and after passing through the suspension mounting hole, the portion with the clamp 42 returns to its original position, allowing the clamp 42 to abut against the end wall of the suspension mounting hole, thereby preventing the suspension from detaching from the suspension bracket 6 along the axial direction of the suspension mounting hole. Furthermore, the suspension bracket 6 in this embodiment specifically includes a bracket body and an outer tube disposed on the bracket body, with the suspension mounting hole disposed in the outer tube.

[0057] Specifically, in this embodiment, as a preferred implementation, we continue to refer to... Figure 2 As shown, each branch pipe is provided with an anti-detachment structure 4. Each anti-detachment structure 4 includes a flange 41 at the first end of the branch pipe and a clamp 42 at the second end of the branch pipe. Both sides of the clamp 42 are provided with notches 43 extending to the second end.

[0058] Here, the combination of the flange 41 and the clamp 42 provides an effective anti-detachment structure 4 for the branch pipe. The flange 41 can be used to prevent the branch pipe from falling off from the first end. The clamp 42 and the notch 43 cooperate, so that during the suspension installation in the suspension mounting hole, the part with the clamp 42 can bend and deform inward along the radial direction of the suspension. After passing through the suspension mounting hole, the part with the clamp 42 returns to its original position, so that the clamp 42 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.

[0059] Meanwhile, as a preferred implementation method, refer to Figure 2 As shown in the figure, each branch pipe in this embodiment has a guide portion 5 at its second end. The guide portion 5 is used to guide the suspension sleeve into the suspension mounting hole.

[0060] The advantage of this design is that a guide section 5 is designed at the second end of each branch pipe, making it easier and more accurate to insert the suspension sleeve into the suspension mounting hole. This structure can improve the efficiency and accuracy of the suspension installation process.

[0061] In the specific structure, the guide portion 5 can be formed by chamfering the second end. It should be understood that rounding the corners is also acceptable. In the preferred embodiment, both the clamp 42 on the second end of each branch pipe and the portion without clamp 42 are provided with guide portions, which can help improve the installation efficiency of the suspension sleeve.

[0062] Furthermore, in this embodiment, as a preferred implementation, such as Figure 2 , Figure 3 and Figure 4As shown, each branch pipe has an inwardly bent section 24 at its end, and adjacent branch pipes are connected by adjacent bent sections 24. This arrangement increases the contact area at the branch pipe connection points, which helps to enhance the connection strength between branch pipes, while ensuring the stability and reliability of the entire suspension sleeve structure.

[0063] It should be understood that in other embodiments, the ends of each branch pipe may not be provided with the bending section 24, and they may be connected by simply abutting the ends of each branch pipe, or the compression joint between each branch pipe may be achieved by other structures.

[0064] In this embodiment, the suspension sleeve can be designed with multiple sub-tubes spliced ​​together, which may make the manufacturing and assembly of the suspension more flexible and convenient. At the same time, different rubbers can be vulcanized on each sub-tube to form suspension assemblies with different properties, which can improve the applicability of the suspension assembly and help reduce processing costs.

[0065] Example 2

[0066] This embodiment relates to a suspension assembly, which includes a suspension bracket 6 having a suspension mounting hole, a suspension inserted into the suspension mounting hole, and the suspension includes the suspension sleeve in Embodiment 1, as well as an inner core 1 and a rubber main spring 3, with the rubber main spring 3 connected between the center tube 22 and the inner core 1.

[0067] Therefore, the inner core 1 is located inside the suspension sleeve, serving to facilitate connection with the powertrain and as the base for connecting the rubber main spring 3. The function of the rubber main spring 3 is to provide the necessary elasticity and damping performance to cope with the load and vibration borne by the suspension assembly. In the specific structure, the inner core 1 has a connecting hole 11 in the middle for mates with the support arm. One end of the support arm is inserted into the connecting hole 11, and the other end is connected to the suspension assembly.

[0068] Furthermore, in this embodiment, as a preferred implementation, refer to... Figure 1 and Figure 3 As shown, the rubber main spring 3 includes an inner core connecting part 31 and a support connecting part 32. The inner core connecting part 31 covers the outer part of the inner core, the upper part of the support connecting part 32 is connected to the inner core connecting part 31 as a whole, and the lower part of the support connecting part 32 is connected to the middle branch tube 22.

[0069] Understandably, the inner core connecting part 31 is the part of the rubber main spring 3 that covers the outside of the inner core 1. It can ensure a tight connection between the rubber main spring 3 and the inner core 1. The main function of the supporting connecting part 32 is to connect the rubber main spring 3 and the center split tube 22. In this way, the rubber main spring 3 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.

[0070] Furthermore, in this embodiment, as a preferred implementation, such as Figure 1 and Figure 4 As shown, both the upper branch pipe 21 and the lower branch pipe 23 are provided with limiting rubber 7, which is used to limit the extreme position of the inner core 1 along the radial movement of the suspension sleeve.

[0071] Here, limiting rubber 7 is provided on both the upper branch pipe 21 and the lower branch pipe 23. When the inner core 1 is subjected to external force or vibration and attempts to move radially inside the suspension sleeve, the limiting rubber 7 provides a physical barrier to effectively and reliably prevent the inner core 1 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 suspension assembly.

[0072] It should be noted that, as Figures 1 to 4 As shown in the diagram, 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 31 abuts against and connects to 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 1 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.

[0073] Secondly, the second limiting rubber 72 is provided on the upper branch pipe 21 or the middle branch pipe 22, and the second limiting rubber 72 is provided on both sides of the inner core 1. Here, the second limiting rubber 72 is provided on the upper branch pipe 21 or the middle branch pipe 22, which can better limit the movement limit position of the inner core 1 in the longitudinal direction of the whole vehicle, which is beneficial to improving the shock absorption and vibration isolation performance of the suspension assembly in the longitudinal direction of the whole vehicle. The second limiting rubber 72 cooperates with the first limiting rubber 71 to improve the shock absorption and vibration isolation performance of the suspension assembly in multiple directions of the whole vehicle.

[0074] 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 23 is located between the second limiting rubber 72 and the rubber main spring 3, that is, at the lower end of the first gap 81. In other embodiments, the second limiting rubber 72 is disposed on the lower branch pipe 23, and the joint point between the upper branch pipe 21 and the lower branch pipe 23 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.

[0075] Furthermore, a first gap 81 is provided between the inner core connecting part 31 and the second limiting rubber 72 in the front-rear direction of the vehicle. The upper part of the first gap 81 extends vertically, and the lower part of the first gap 81 extends downward while tilting away from the inner core 1, which facilitates the arrangement of the bending section 24. Moreover, the shape of the first gap 81 changes with the shape of the upper part of the rubber main spring 3.

[0076] Thus, the aforementioned bent section 24 can be inserted into the first gap 81 for easy arrangement. The connection between adjacent branch pipes via the bent section 24 increases the connection area between adjacent branch pipes, which helps to improve the structural reliability of the spliced ​​suspension sleeve and also prevents the branch pipes from detaching from the suspension bracket 6 along the axial direction of the suspension mounting hole.

[0077] Furthermore, the lower part of the support connection part 32 is provided with a notch 43, the third limiting rubber 73 is provided on the lower branch pipe 23 and located in the notch, and a second gap 82 is provided between the third limiting rubber 73 and the support connection part 32.

[0078] A notch is provided at the lower part of the support connection 32 to accommodate the third limiting rubber 73, which can better limit the lower extreme position of the inner core 1. The second gap 82 allows the support connection 32 to have a certain 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 to make the shock absorption and vibration isolation performance of the suspension assembly even better.

[0079] It should be noted that the second gap 82 in this embodiment is specifically in the shape of an inverted U, which has a good limiting effect in both the vertical and longitudinal directions of the vehicle. Furthermore, in the suspension of this embodiment, any one or two of the first limiting rubber 71, the second limiting rubber 72, and the third limiting rubber 73 can be provided.

[0080] In a preferred embodiment, the limiting rubber 7 and the rubber main spring 3 have different stiffnesses. In a preferred embodiment, the stiffness of the limiting rubber 7 is greater than the stiffness of the rubber main spring 3, which can achieve a better limiting effect. It should be understood that, in addition, the stiffness of the limiting rubber 7 can also be equal to or less than the stiffness of the rubber main spring 3.

[0081] Still refer to Figure 1 As shown, in this embodiment, the first limiting rubber 71, the second limiting rubber 72 and the third limiting rubber 73 have the same stiffness and relatively high stiffness, while the rubber main spring 3 has low to medium stiffness.

[0082] It should be understood that the stiffness of the first limiting rubber 71, the second limiting rubber 72, and the third limiting rubber 73 may also be different from each other. For example, in a preferred embodiment, the first limiting rubber 71 and the second limiting rubber 72 have the same stiffness, and the third limiting rubber 73 has the same stiffness as the rubber main spring 3.

[0083] This embodiment also relates to a vehicle equipped with the aforementioned suspension assembly.

[0084] The vehicle in this embodiment has the same beneficial effects as the aforementioned suspension assembly compared to the prior art, and will not be described again here.

[0085] 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.
