Description

Technical Field

[0001] This application relates to the field of vehicle chassis technology, and in particular to a suspension assembly. This application also relates to a vehicle using this suspension assembly. Background Technology

[0002] The transverse front-wheel-drive powertrains currently used in vehicles mostly employ pendulum-type mounts. Pendulum-type mounts offer advantages such as simple structure, low cost, good vibration isolation, convenient design, and ease of overall vehicle layout, leading to their increasingly widespread application in the automotive mounting system field.

[0003] With the rapid development of vehicles, hybrid vehicles with both fuel and electric power are being used more and more. However, when both fuel and electric power are used at the same time, the torque can reach its maximum value and is much greater than that of conventional power. The existing suspension structure has poor strength, and the inner core is connected to the powertrain by bolts, which is easy to loosen, thus easily leading to the failure of the suspension assembly. Utility Model Content

[0004] In view of this, this application aims to provide a suspension assembly to improve its application reliability.

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

[0006] A suspension assembly includes a sleeve that can be mounted to a vehicle body, an outer tube inserted into the sleeve, an inner core inserted into the outer tube, an elastic body connecting the outer tube and the inner core, and a powertrain connection portion connected to the inner core.

[0007] The outer tube is provided with a first clearance portion for avoiding the powertrain connection portion; the sleeve is provided with a second clearance portion for avoiding the powertrain connection portion;

[0008] The powertrain connection extends radially outward from the inner core along the outer tube and has an exposed portion that passes through the first clearance portion and the second clearance portion and protrudes outside the outer tube. The powertrain connection is connected to the powertrain through the exposed portion.

[0009] Furthermore, the powertrain connection portion is provided with a cavity, which extends along the extension direction of the powertrain connection portion.

[0010] Furthermore, the inner core includes an inner tube that is hollow inside, and the axial direction of the inner tube is consistent with the axial direction of the outer tube.

[0011] Furthermore, the first clearance portion includes a clearance hole provided on the outer tube, and a gap is provided between the edge of the clearance hole and the powertrain connection portion; and / or, the second clearance portion includes a clearance groove provided on the sleeve, the clearance groove being able to avoid the powertrain connection portion during the insertion of the outer tube into the sleeve.

[0012] Furthermore, in the axial direction of the inner tube, the middle part of the inner tube is connected to the powertrain connection part.

[0013] Furthermore, in a direction orthogonal to the extension direction of the powertrain connection portion, both sides of the inner tube are connected to the powertrain connection portion.

[0014] Furthermore, openings are provided on both sides of the inner tube in a direction orthogonal to the extension direction of the powertrain connection portion;

[0015] A sealing part is connected between the powertrain connection and the inner tube to seal each of the openings.

[0016] Furthermore, at least one end of the elastomer is provided with a recessed portion, which is recessed into the interior of the elastomer itself.

[0017] Furthermore, the elastic body has multiple recesses at both ends, and these multiple recesses at both ends are arranged at intervals around the inner core.

[0018] Compared with related technologies, this application has the following advantages:

[0019] (1) The suspension assembly described in this application includes both a sleeve and an outer tube by installing a sleeve on the vehicle body and inserting the outer tube into the sleeve. This improves the structural strength and installation reliability of the suspension assembly. The suspension assembly is also easier to install and assemble. The powertrain connection part is directly connected to the inner core and passes through the first and second clearance parts. It does not need to be connected to the powertrain connection part by bolts. This eliminates the need for bolts and avoids the problem of bolt loosening, thereby improving the reliability of the application of the suspension assembly.

[0020] (2) A cavity is provided in the powertrain connection part and the cavity extends along the extension direction of the powertrain connection part, which can effectively reduce the weight of the powertrain connection part, meet the lightweight design requirements of the vehicle, and at the same time make the powertrain connection part have good bending and torsional resistance.

[0021] (3) The inner core is set as an inner tube, which can be made using existing standard profiles at a lower cost. This makes the axial direction of the inner tube consistent with that of the outer tube, facilitating overall layout.

[0022] (4) The first clearance part is set as a clearance hole, which is simple and convenient to process. A gap is provided between the edge of the clearance hole and the powertrain connection part, which can better prevent the powertrain connection part from impacting the outer tube and causing abnormal noise. The second clearance part is set as a clearance groove, which is simple and convenient to process. At the same time, the setting of the clearance groove makes it easy for the outer tube to be smoothly inserted into the sleeve, and makes the sleeve lighter, which meets the lightweight design requirements of the vehicle.

[0023] (5) Connect the powertrain connection part to the middle part of the inner tube in the axial direction of the inner tube so that the suspension assembly is subjected to uniform force and the application reliability of the suspension assembly is improved.

[0024] (6) In a direction orthogonal to the extension direction of the powertrain connection, both sides of the inner tube are connected to the powertrain connection, which helps to improve the reliability and stability of the connection between the inner tube and the powertrain connection.

[0025] (7) Openings are provided on both sides of the inner tube, and a sealing part is connected between the powertrain connection part and the inner tube. This can increase the connection area between the inner tube and the powertrain connection part, and improve the reliability and stability of the connection between the inner tube and the powertrain connection part.

[0026] (8) A recessed portion is provided at the end of the elastomer and the recessed portion is recessed into the elastomer itself. This not only reduces the amount of material used and the cost of the material, but also helps to improve the shock absorption performance of the elastomer.

[0027] (9) By setting multiple recesses and arranging them around the inner core at intervals, the weight of the elastic part can be reduced, and the elastomer can have better shock absorption performance.

[0028] Another object of this application is to provide a vehicle having the suspension assembly described above.

[0029] The vehicle described in this application includes a suspension assembly that includes both a sleeve and an outer tube, which can improve the structural strength and installation reliability of the suspension assembly. The suspension assembly is also easier to install and assemble. The powertrain connection part is directly connected to the inner core, without the need for bolts to connect to the powertrain connection part. This eliminates the need for bolts and avoids the problem of bolt loosening, thereby improving the reliability of the suspension assembly application. Attached Figure Description

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0048] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0049] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0050] The embodiments of the first aspect of this application provide a suspension assembly with high structural strength, convenient assembly, and high application reliability, thus having good practicality.

[0051] In related technologies, with the rapid development of vehicle technology, automobiles have evolved from traditional fuel vehicles to electric vehicles, and then gradually to hybrid vehicles that simultaneously achieve both fuel and electric power. Hybrid vehicles are becoming increasingly popular with consumers because they combine the advantages of both fuel and electric vehicles.

[0052] In hybrid vehicles, the powertrain is mostly arranged in a transverse front-wheel-drive configuration, and this type of powertrain is often mounted on the vehicle body using pendulum-type suspension. Pendulum-type suspension has advantages such as simple structure, low cost, good vibration isolation effect, convenient design, and ease of overall vehicle design and layout, and its application in the field of automotive suspension systems is becoming increasingly widespread.

[0053] In transversely mounted vehicles that use pendulum-type suspension (with the left or right suspension as the suspension point, which can be fixed at the top and swing at the bottom like a pendulum), the rear suspension is usually the main structure for torsional limiting in the X direction (the length direction of the vehicle, i.e., the front-to-back direction of the vehicle).

[0054] With the rapid development of vehicles, hybrid vehicles with both fuel and electric power are being used more and more. However, when both fuel and electric power are used at the same time, the torque can reach its maximum value and is much greater than that of conventional power. The existing suspension structure has poor strength, and the inner core is connected to the powertrain by bolts, which is easy to loosen, thus easily leading to the failure of the suspension assembly.

[0055] It should be noted that powertrains have different structures on different vehicle models. For example, the powertrain of a gasoline vehicle includes an engine and a transmission, while the powertrain of a hybrid vehicle includes an engine and an electric drive. The powertrain in this embodiment can be the powertrain of a gasoline vehicle, the powertrain of a hybrid vehicle, or the powertrain of a pure electric vehicle.

[0056] In view of this, in order to overcome the shortcomings of the related technology, the suspension assembly of this embodiment combines... Figure 1 The structure shown, in terms of overall design, the suspension assembly mainly includes a sleeve 6, an outer tube 1, an elastomer 3, and a powertrain connection part 4.

[0057] The suspension assembly is mounted to the vehicle body via a sleeve 6, specifically on the subframe of the vehicle body. It should be noted that the connection between the sleeve 6 and the subframe is a fixed connection. In a preferred embodiment, the sleeve 6 is welded to the subframe, which is more convenient for processing.

[0058] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, the aforementioned outer tube 1 is inserted into the sleeve 6, the inner core 2 is inserted into the outer tube 1, and the elastomer 3 is connected between the outer tube 1 and the inner core 2. The powertrain connection part 4 is connected to the inner core 2, and the powertrain connection part 4 is used to connect the powertrain.

[0059] Specifically, the outer tube 1 is provided with a first clearance portion 101 for avoiding the powertrain connection portion 4, and the sleeve 6 is provided with a second clearance portion 601 for avoiding the powertrain connection portion 4. The powertrain connection portion 4 extends outward from the inner core 2 along the radial direction of the outer tube 1 and has an exposed portion 401 that passes through the first clearance portion 101 and the second clearance portion 601 and is exposed outside the outer tube 1. The powertrain connection portion 4 is connected to the powertrain through the exposed portion 401.

[0060] It should be noted that, in a preferred embodiment, the sleeve 6 is welded and fixed to the vehicle body, and the outer tube 1 is inserted into the sleeve 6. Generally, the outer tube 1 is made of metal, and the sleeve 6 is also made of metal. The outer tube 1 is interference-fitted into the sleeve 6, which facilitates assembly, improves the structural strength of the suspension assembly itself, and enhances the stability and reliability of the connection between the suspension assembly and the subframe.

[0061] In a preferred embodiment, the sleeve 6 has an annular cross-section, which allows it to be manufactured using existing round tubes, resulting in lower processing costs. It should be understood that the cross-section of the sleeve 6 can be square, rhomboid, polygonal, etc., in addition to being circular.

[0062] It should be noted that the shape of the outer tube 1 is adapted to the shape of the sleeve 6. That is to say, the shape of the sleeve 6 is consistent with the shape of the outer tube 1. For example, in the embodiment of this application, the cross-section of the sleeve 6 is circular, and the cross-section of the outer tube 1 is also circular.

[0063] It should be understood that when the cross-section of the sleeve 6 is square, the cross-section of the outer tube 1 is also square, so that the outer tube 1 can be securely inserted into the sleeve 6, thereby improving the reliability of the connection between the outer tube 1 and the sleeve 6.

[0064] Furthermore, in a preferred embodiment, the inner core 2 is inserted through the center of the outer tube 1, and the powertrain connection part 4 is preferably connected to the inner core 2 by welding. The powertrain connection part 4 passes through the first clearance part 101 and the second clearance part 601, and has an exposed portion 401 exposed outside the outer tube 1.

[0065] With this configuration, the inner core 2 is connected to the powertrain connection part 4 by welding, eliminating the need for bolts. This avoids bolt loosening and improves the reliability of the mounting assembly. Furthermore, it eliminates the need for tightening torque, reducing subsequent torque inspection steps.

[0066] In order to meet the lightweight design requirements of vehicles, such as Figure 4 and Figure 5As shown, in some exemplary embodiments, the powertrain connection portion 4 is provided with a cavity 402, which extends along the extending direction of the powertrain connection portion 4.

[0067] In this embodiment, a cavity 402 is provided within the powertrain connection portion 4, which reduces the amount of solid material used in the powertrain connection portion 4, thereby effectively reducing the overall weight and cost, meeting the lightweight requirements of vehicles. When applied to vehicles, weight reduction helps reduce energy consumption, improve the fuel economy of gasoline vehicles, or extend the driving range of electric vehicles.

[0068] In addition, lighter weight results in less inertia, making the powertrain more agile and responsive during acceleration, deceleration, and steering. This improves powertrain efficiency and enhances vehicle performance and handling stability.

[0069] In a preferred embodiment, the powertrain connection part 4 is made of square tubing, which allows for the use of existing steel profiles and reduces processing costs. It should be understood that the powertrain connection part 4 can also be made of round tubing in addition to square tubing.

[0070] After one end of the powertrain connection part 4 is welded to the inner core 2, a portion of the powertrain connection part 4 protrudes outside the outer tube 1, namely the aforementioned exposed portion 401. In this way, the powertrain connection part 4 can be connected to the powertrain using the exposed portion 401. The specific connection method can refer to existing connection methods, such as flexible connection methods, which will not be described in detail here.

[0071] It should be noted that, in a preferred embodiment, the exposed portion 401 of the powertrain connection part 4 may also adopt a structure other than a square tube, such as casting, to facilitate assembly with existing powertrains. Specifically, the structure of the exposed portion 401 can refer to existing structures, while the insertion portion of the powertrain connection part 4 that inserts into the outer tube 1 adopts the structure mentioned in this embodiment, and the insertion portion and the exposed portion 401 are welded together.

[0072] Reference Figure 3 As shown, in some exemplary embodiments, the inner core 2 includes an internally hollow inner tube whose axial direction is aligned with that of the outer tube 1.

[0073] In this embodiment, the inner core 2 is made of an inner tube, which can be manufactured using existing standard steel profiles, thus reducing costs. The inner core 2 is also lightweight and has good bending and torsional resistance. For example, in this embodiment, the inner core 2 uses an inner tube with a hexagonal cross-section, which is lightweight and has excellent bending and torsional resistance. It also facilitates connection with the powertrain connection part 4 described below, improving the stability and reliability of the connection with the powertrain connection part 4.

[0074] It should be noted that the axial direction of the inner tube is consistent with that of the outer tube 1. With this arrangement, the power assembly connection part 4 can be easily inserted into the outer tube 1, making it easier to connect the inner tube to the power assembly connection part 4. The power assembly connection part 4 can easily connect to the power assembly, and it does not affect the overall interference fit of the inner tube, the elastomer 3 and the outer tube 1 in the sleeve 6, making the overall installation and arrangement more convenient.

[0075] like Figure 6 As shown in the figure, the structure of the outer tube 1 is illustrated. Specifically, the aforementioned first clearance portion 101 includes a clearance hole provided on the outer tube, and a gap is provided between the edge of the clearance hole and the powertrain connection portion 4.

[0076] In this embodiment, the first clearance portion 101 is configured as a clearance hole, which can better ensure the integrity of the overall structure of the outer tube 1, thereby ensuring the structural strength of the suspension assembly. In some examples, for example... Figure 6 The state shown is along the axial direction of outer tube 1, that is... Figure 6 As shown in the vertical direction, the clearance hole is located in the middle of the axial direction of the outer tube 1, which can better ensure the integrity of the outer tube 1 and thus improve the structural strength of the outer tube 1.

[0077] In a preferred embodiment, the gap between each side of the powertrain connection portion 4 and the edge of the clearance hole is between 1mm and 20mm, such as 1mm, 5mm, 10mm, 12mm, 16mm, 20mm, etc. It should be understood that leaving a gap between the powertrain connection portion 4 and the edge of the clearance hole can better prevent impact noise between the powertrain connection portion 4 and the outer pipe 1.

[0078] In some exemplary embodiments, the sleeve 6 is structured as follows: Figure 2 As shown, the aforementioned second clearance portion 601 includes a clearance groove provided on the sleeve 6, which can avoid the powertrain connection portion 4 during the insertion of the outer tube 1 into the sleeve 6. Specifically, during the insertion of the outer tube 1 into the sleeve 6, in order to prevent the powertrain connection portion 4 from interfering with the sleeve 6, which would lead to assembly difficulties or even make assembly impossible, the second clearance portion 601 is set as a clearance groove in the above structure. This provides additional space for the powertrain connection portion 4, preventing it from interfering with the sleeve 6 during insertion, thereby improving the stability and smoothness of the insertion of the outer tube 1 into the sleeve 6.

[0079] Without the clearance groove, the powertrain connection part 4 would collide and rub against the sleeve 6 during insertion, potentially causing damage or deformation to the powertrain connection part 4. The clearance groove effectively avoids this direct physical contact, allowing the powertrain connection part 4 to be smoothly inserted into the sleeve 6.

[0080] It should be understood that gaps are also provided between the two side walls and bottom wall of the clearance groove and the powertrain connection part 4, and each gap is between 1mm and 20mm, for example, 1mm, 5mm, 10mm, 12mm, 16mm, 20mm, etc. In a preferred embodiment, the opening size of the clearance groove is larger than the opening size of the clearance hole, which can better prevent impact noise between the powertrain connection part 4 and the sleeve 6. Figure 2 As shown, in the illustrated direction, the upper end of the clearance groove has an opening, from... Figure 2 In the state shown, the open end of the clearance groove is located at the upper end of the sleeve 6, and in the axial direction of the sleeve 6, that is... Figure 2 In the vertical direction shown, the depth of the clearance groove is approximately two-thirds of the height of the sleeve 6. With this configuration, when the outer tube 1 is inserted into the sleeve, the powertrain connection part 4 is located approximately at the center of the sleeve 6 in the axial direction, which provides good installation stability. At the same time, when used in a vehicle, the forces on each component are relatively balanced, the components of the suspension assembly are not easily damaged, and the application reliability is high.

[0081] It should be understood that by placing the open end of the clearance groove at the upper end of the sleeve 6, the process of inserting the outer tube 1 into the sleeve 6 is from top to bottom. Alternatively, the open end of the clearance groove can be placed at the lower end of the sleeve 6, in which case the process of inserting the outer tube 1 into the sleeve 6 is from bottom to top.

[0082] It should be noted that setting the second clearance part 601 as a clearance groove is only a preferred embodiment, which allows the whole consisting of the outer tube 1, the elastomer 3 and the inner core 2 to be conveniently pressed into the sleeve 6. It should be understood that the second clearance part 601 may not be set as a clearance groove, for example, it may be set as a clearance hole. In this case, the sleeve 6 may include, for example, a first half tube and a second half tube. It is also possible to form the sleeve 6 by the first half tube and the second half tube.

[0083] It should also be noted that, in a preferred embodiment, the thickness of the sleeve 6 is greater than the thickness of the outer tube 1, so that both structural strength and weight can be taken into account, making the overall weight of the suspension assembly lighter and having higher structural strength.

[0084] Still refer to Figure 1 As shown, in some of the exemplary embodiments, the powertrain connection 4 is connected to the middle of the inner tube in the axial direction of the inner tube.

[0085] In this preferred embodiment, since the axial direction of the inner tube is consistent with that of the outer tube 1, and the powertrain connection part 4 extends radially along the outer tube 1, the powertrain connection part 4 is connected to the middle of the inner tube. The resulting suspension assembly has the powertrain connection part 4 located in the middle of the inner tube along its axial direction. When this suspension assembly is applied to a vehicle, the suspension assembly is subjected to uniform force, which helps to improve the application reliability of the suspension assembly.

[0086] like Figure 1 and combined Figure 4 As shown, in some exemplary embodiments, both sides of the inner tube are connected to the powertrain connection 4 in a direction orthogonal to the extending direction of the powertrain connection 4.

[0087] like Figure 4 In the state shown, in this preferred example, both sides of the inner tube are connected to the powertrain connection part 4 in a direction orthogonal to the extension direction of the powertrain connection part 4, which helps to improve the reliability and stability of the connection between the inner tube and the powertrain connection part 4.

[0088] Continue to refer to Figure 1 , Figure 4 and combined Figure 5 As shown, in some exemplary embodiments, openings 201 are provided on both sides of the inner tube in a direction orthogonal to the extension direction of the powertrain connection 4, and a sealing part 5 is connected between the powertrain connection 4 and the inner tube to seal each opening 201.

[0089] Reference Figure 3 and combined Figure 1 and Figure 4 As shown, the inner tube has openings 201 on both sides, and a connecting hole 202 on the side of the inner tube facing the powertrain connection part 4. The openings 201 on both sides communicate with the connecting hole 202. The aforementioned powertrain connection part 4 is inserted into the connecting hole 202, and after the powertrain connection part 4 is welded to the inner core 2, the sealing part 5 can seal the openings 201 on both sides.

[0090] For example Figure 4 and Figure 5 In the structure shown, in a direction orthogonal to the extending direction of the powertrain connection portion 4, both sides of the sealing portion 5 include a second sealing plate 502 and two other first sealing plates 501. (Refer to...) Figure 1 As shown, the direction of extension of the powertrain connection part 4 is the direction shown in f1, and the direction orthogonal to the direction of extension of the powertrain connection part 4 is the direction shown in f2.

[0091] In a preferred embodiment, the second blocking plate 502 is integrally formed on the powertrain connection part 4, which is convenient for processing. When the powertrain connection part 4 is assembled with the inner core 2, the two second blocking plates 502 are arranged axially on the outer tube 1, thereby blocking the upper and lower parts of the opening 201.

[0092] In a preferred embodiment, since the inner core 2 is a hollow hexagonal prism tube, the aforementioned connecting hole 202 is opened on one of the side plates, while the aforementioned two openings 201 are both opened on the two side plates. When the powertrain connection part 4 is assembled with the inner core 2, the aforementioned second blocking plate 502 can only block the middle part of the opening 201 in the axial direction of the outer tube 1. The second blocking plate 502, in conjunction with the first blocking plates 501 at its upper and lower ends, can completely block the opening 201.

[0093] With this configuration, both first blocking plates 501 are triangular in shape. The inherent stability of the triangle structure enhances the reliability of the connection between the powertrain connection 4 and the inner core 2. Furthermore, the design of the sealing part 5, including the first blocking plate 501 and the second blocking plate 502, facilitates the processing of both the powertrain connection 4 and the inner core 2, and also makes their assembly easier, thus ensuring the reliable application of the powertrain connection 4.

[0094] In addition, this connection structure allows for a larger connection area between the powertrain connection part 4 and the inner core 2, which can significantly improve the connection reliability between them. It should be understood that, besides including the second blocking plate 502 and two other first blocking plates 501 in the sealing part 5, in actual installation, the second blocking plate 502 and the two first blocking plates 501 can also be machined as a single unit and then connected to the powertrain connection part 4 and the inner core 2.

[0095] It should be noted that, in actual processing, the powertrain connection part 4 including the second blocking plate 502 can pass through the aforementioned first clearance part 101, and then the powertrain connection part 4 can be welded together with the inner core 2. Then, each of the first blocking plates 501 can be welded together, and then the inner core 2 and the outer tube 1 can be vulcanized and connected together by an elastomer 3 such as rubber.

[0096] With this connection structure, since the aforementioned opening 201 has been blocked by the sealing part 5, the rubber will not enter the interior of the inner core 2 during the vulcanization process, which can reduce the manufacturing difficulty of the mold and reduce the cost of the mold and vulcanization connection.

[0097] To improve the damping performance of the suspension assembly, for example Figure 1 As shown, in some exemplary embodiments, at least one end of the elastomer 3 is provided with a recessed portion that is recessed into the interior of the elastomer 3 itself.

[0098] In some examples, the aforementioned recessed portion is a groove 301, and at least one end of the elastic body 3 is provided with a groove 301, which is recessed into the elastic body 3 itself. That is to say, it is possible to provide a groove 301 at either end of the elastic body 3, or it is possible to provide a groove 301 at both ends of the elastic body 3.

[0099] In this application, a groove 301 is provided at the end of the elastomer 3 and the groove 301 is recessed into the elastomer 3 itself. This not only reduces the amount of material used and the cost of the material, but also helps to improve the shock absorption performance of the elastomer 3.

[0100] It should be noted that in some preferred examples, both ends of the elastomer 3 are provided with grooves 301, and the grooves 301 at both ends are recessed into the elastomer 3 itself, which can effectively reduce the amount of material used in the elastomer 3 and make the elastomer 3 have excellent shock absorption performance.

[0101] Continue to refer to Figure 1 As shown, the grooves 301 at both ends of the elastic body 3 have the same shape and structure along the axial direction of the outer tube 1. Therefore, the following description will take the groove 301 at one end of the elastic body 3 as an example.

[0102] In some exemplary embodiments, the elastic body 3 has multiple recesses at both ends, and the multiple recesses at both ends are arranged at intervals around the inner core 2.

[0103] As in this application, the recessed portion is a groove 301, and there are multiple grooves 301 at both ends of the elastic body 3, and the multiple grooves 301 at both ends are arranged at intervals around the inner core 2.

[0104] Here, multiple grooves 301 are provided and arranged around the inner core 2 at intervals, which has a good effect of reducing the weight of the elastic part and at the same time makes the elastic body 3 have better shock absorption performance.

[0105] For example Figure 1 As shown, each end of the elastomer 3 has four grooves 301. In the direction of extension of the powertrain connection part 4, two grooves 301 are provided on both sides of the inner tube. These two grooves 301 are symmetrically arranged about the center line of the inner core 2 in the direction of extension of the powertrain connection part 4, and these two grooves 301 extend in a direction orthogonal to the direction of extension of the powertrain connection part 4.

[0106] It should be noted that, in a preferred embodiment, the recesses at both ends of the elastic body 3 are symmetrically arranged about the cross-section of the middle part of the inner tube along the axial direction. For example, in one example of this application, the recesses at corresponding locations at both ends of the elastic body 3 are connected, thus forming a through hole that penetrates the elastic body 3 along the axial direction of the inner tube, so that the elastic body 3 has a better vibration damping effect.

[0107] Meanwhile, in a direction orthogonal to the extension direction of the powertrain connection part 4, two other grooves 301 are placed on both sides of the inner core 2, so that the four grooves 301 cooperate to improve the vibration reduction effect of the suspension assembly in these two directions.

[0108] It should be noted that in the preferred embodiment of this application, there are four grooves 301 at each end of the elastomer 3. It should be understood that the number of grooves 301 at each end of the elastomer 3 can also be other, such as four, five, or six grooves 301 at each end of the elastomer 3.

[0109] It is worth noting that, regarding this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still... Figure 1 As shown, the suspension assembly includes a sleeve 6 welded to the subframe, an outer tube 1 interference-fitted into the sleeve 6, an inner core 2 inserted into the outer tube 1, an elastic body 3 connecting the outer tube 1 and the inner core 2, and a powertrain connection part 4 welded to the inner core 2.

[0110] The outer tube 1 is provided with a clearance hole for avoiding the powertrain connection part 4, and the sleeve 6 is provided with a clearance groove for avoiding the powertrain connection part 4. The edges of the clearance groove and the clearance hole are provided with gaps between them and the powertrain connection part 4.

[0111] The powertrain connection part 4 extends outward from the inner core 2 along the radial direction of the outer tube 1 and has an exposed portion 401 that passes through the clearance hole and clearance groove and is exposed outside the outer tube 1. The powertrain connection part 4 is connected to the powertrain through the exposed portion 401.

[0112] The powertrain connection part 4 has a cavity 402 that extends along the extension direction of the powertrain connection part 4. The inner core 2 is an inner tube, and the axial direction of the inner tube is consistent with the axial direction of the outer tube 1.

[0113] In a direction orthogonal to the extension direction of the powertrain connection part 4, openings 201 are provided on both sides of the inner tube, and a sealing part 5 is provided on the powertrain connection part 4 and / or the inner tube to seal each opening 201. Multiple grooves 301 are provided at both ends of the elastic body 3, and the multiple grooves 301 at each end are arranged at intervals around the inner core 2.

[0114] In the above preferred embodiment, the suspension assembly includes both sleeve 6 and outer tube 1, which can improve the structural strength and installation reliability of the suspension assembly. The suspension assembly is also easier to install and assemble. The powertrain connection part 4 is welded to the inner core 2, and there is no need to connect it to the powertrain connection part 4 with bolts. This eliminates the need for bolts and avoids the problem of bolt loosening, thereby improving the reliability of the application of the suspension assembly.

[0115] In addition, a clearance hole is provided, with a gap between the edge of the clearance hole and the powertrain connection part 4, which can effectively prevent the powertrain connection part 4 from impacting and causing abnormal noise with the outer tube 1. The clearance groove is provided to facilitate the smooth insertion of the outer tube 1 into the sleeve 6, and to make the sleeve lighter, which meets the lightweight design requirements of the vehicle.

[0116] Furthermore, the cavity 402 within the powertrain connection portion 4 extends along the extension direction of the powertrain connection portion 4, which can effectively reduce the weight of the powertrain connection portion 4, meeting the lightweight design requirements of the vehicle, while also giving the powertrain connection portion 4 better bending and torsional resistance. The inner core 2 uses an inner tube, which can be manufactured using existing standard profiles, resulting in lower costs. This ensures that the axial direction of the inner tube is aligned with the axial direction of the outer tube 1, facilitating overall layout.

[0117] The connection method between the powertrain connection part 4 and the inner core 2 is limited, which increases the connection area between the inner tube and the powertrain connection part 4, thus improving the reliability and stability of the connection. The groove 301 provided at the end of the elastic body 3 has a good effect on reducing the weight of the elastic part, and at the same time makes the elastic body 3 have better shock absorption performance.

[0118] An embodiment of the second aspect of this application provides a vehicle having the suspension assembly described above.

[0119] In this embodiment, the vehicle uses the above-mentioned suspension assembly. Since the suspension assembly includes both the sleeve 6 and the outer tube 1, the structural strength and installation reliability of the suspension assembly can be improved. The installation and assembly of the suspension assembly are also more convenient. The powertrain connection part 4 is connected to the inner core 2 without the need for bolts. This eliminates the need for bolts and avoids the problem of bolt loosening, thereby improving the reliability of the application of the suspension assembly.

[0120] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
