Description

Technical Field

[0001] This application relates to the field of vehicle vibration reduction technology, and in particular to a suspension device and a vehicle. Background Technology

[0002] Currently, vehicle exhaust systems are typically mounted on the vehicle body via a suspension structure. There are two main types of suspension structures: First, the suspension structure consists only of rubber blocks, with each rubber block connected to two hooks to achieve the connection between the exhaust system and the vehicle body. These two hooks are located on the vehicle body and the exhaust system, respectively. Second, the suspension structure consists of rubber blocks and a vulcanized metal frame on the outer circumference of the rubber blocks. The metal frame is fixed to the vehicle body (or chassis) via a connecting structure. On the exhaust system side, hooks pass through the rubber blocks to connect and fix the exhaust system to the vehicle body.

[0003] In related technologies, if the suspension structure is made of only rubber blocks, it is prone to breakage after aging; if the suspension structure is made of rubber blocks and a metal frame surrounding the rubber blocks, the rigidity of the suspension device can be improved, but the buffering and vibration absorption effect of the suspension structure will be weak.

[0010] According to some embodiments of this application, the connecting portion of each connecting arm is constructed as a limiting flange, which abuts against the side wall of the reinforcing frame away from the rubber arm, ensuring the fit between the connecting portion and the reinforcing frame.

[0011] According to some embodiments of this application, in the projection in the first direction, the outer peripheral wall of the head of each segment of the rubber arm with the mounting hole extends in an arc shape; there are three reinforcing frames, each of which includes: a main connecting segment, which is fitted to the rubber arm and located between the heads of two segments of the rubber arm; and two arc-shaped connecting segments, which are respectively connected to the two ends of the main connecting segment, and each arc-shaped connecting segment is fitted to a portion of the outer peripheral wall of the head.

[0012] According to some embodiments of this application, the rubber body includes two rubber arms arranged in a V-shape, one of the three mounting holes is located at the connection of the two rubber arms, and the other two mounting holes are respectively located at the free ends of the two rubber arms.

[0013] According to some embodiments of this application, the connecting portion of each connecting arm is configured to extend in an arc shape, the connecting portion is embedded in the rubber body, and the connecting portion is located on the circumferential outer side of the mounting hole, and surrounds part of the mounting hole in the circumferential direction.

The first mounting hole and the second mounting hole are respectively formed at the free ends of the two rubber arms, and the third mounting hole is formed at the connection of the two rubber arms. The three connecting arms are a first connecting arm, a second connecting arm, and a third connecting arm. The first connecting arm and the second connecting arm are connected and connected at the open ends of the two rubber arms that are arranged in a V-shape. The third connecting arm is connected between the connection area of ​​the first connecting arm and the second connecting arm and the connection of the two rubber arms.

[0016] According to some embodiments of this application, the first connecting arm and the second connecting arm are integrally formed.

[0017] According to some embodiments of this application, the third connecting arm includes a third arm body, one end of which is connected to the connection point of the two rubber arms; the connecting assembly further includes: a first connecting piece, the first connecting piece extending in an arc shape, with its arc-shaped opening facing one of the rubber arms, the first connecting piece connecting between the other end of the first arm body and the third arm body; and a second connecting piece, the second connecting piece extending in an arc shape, with its arc-shaped opening facing the other rubber arm, the second connecting piece connecting between the other end of the second arm body and the third arm body.

[0024] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0025] The following is for reference. Figures 1-5 Description of a hanging device 100 according to an embodiment of this application.

[0026] The suspension device 100 according to the embodiments of this application can be applied to vehicles, such as the suspension of an exhaust system and a vehicle body. Taking the use of the suspension device 100 to suspend the exhaust system to the vehicle body as an example, the suspension device 100 according to the embodiments of this application is described.

[0027] Currently, vehicle exhaust systems are typically suspended within the vehicle body via a suspension structure. This suspension structure, connecting the exhaust system to the vehicle frame, bears the weight of the exhaust system. Simultaneously, it positions, cushions, and absorbs vibrations from the exhaust system, enhancing overall vehicle ride comfort. During vehicle operation, the exhaust system vibrates vertically due to road surface vibrations and its own weight. The suspension structure utilizes tension and compression to cushion and absorb these vibrations.

[0028] Furthermore, there are two main ways to connect the suspension structure: First, the suspension structure consists only of rubber suspension blocks, and the rubber suspension blocks are respectively connected to two hooks to achieve the suspension connection between the exhaust system and the vehicle body. The two hooks are respectively set on the vehicle body and the exhaust system. Second, the suspension structure consists of rubber suspension blocks and a vulcanized metal frame set on the outer circumference of the rubber suspension blocks. The metal frame is fixed to the vehicle body (or frame) through the connecting structure on the metal frame. The exhaust system side is connected to the vehicle body by passing through the rubber suspension blocks with hooks.

[0029] In related technologies, if the suspension structure is made of only rubber blocks, the suspension structure is prone to breakage after aging; if the suspension structure is made of rubber blocks and a metal frame surrounding the rubber blocks, the rigidity of the suspension device 100 can be improved, but the buffering and vibration absorption effect of the suspension structure will be weak.

[0030] Combination Figures 1-5 As shown, the hanging device 100 according to an embodiment of this application includes: a rubber body 1 and a connecting component 2.

[0031] Reference Figure 1 and Figure 3 As shown, the rubber body 1 has three mounting holes 101 that are arranged through the first direction. The mounting holes 101 are used to connect the rubber body 1 to one side of the vehicle body or the exhaust system side, so that the rubber body 1 can buffer and absorb the vibration between the exhaust system and the vehicle body.

[0032] Furthermore, the connecting component 2 includes three connecting arms 21 arranged in a Y shape. The free ends of the three connecting arms 21 form connecting portions 214, which are fixedly engaged with the rubber body 1 to achieve the connection and fixation between the connecting component 2 and the rubber body 1. Each connecting arm 21 is partially embedded in the rubber body 1, and each connecting arm 21 has a tendency to pull the rubber body 1 toward the intersection area of ​​the three connecting arms 21. This can prevent the rubber body 1 from being overstretched, causing excessive deformation and cracking, and reduce the risk of damage to the rubber body 1.

[0033] Combination Figures 1-5As shown, in the projection of the first direction, the three mounting holes 101 are arranged in a non-collinear three-point arrangement, and the intersection area of ​​the three connecting arms 21 is located within the area enclosed by the center line connecting the three mounting holes 101.

[0034] Specifically, when the three mounting holes 101 are arranged in a non-collinear three-point configuration, they form a triangular arrangement, with each mounting hole 101 located at a vertex of the triangle. This allows for three-point assembly between the exhaust system and the vehicle body, improving the reliability of the assembly. Simultaneously, the triangular arrangement of the three mounting holes 101 enhances the structural strength and stress resistance of the rubber body 1, providing effective cushioning against vibration and impact.

[0035] The triangle formed by the center positions of the three mounting holes 101 is preferably constructed as an equilateral triangle, so that the distance between the positions of each mounting point in the hanging device 100 is the same (i.e., the distance between the center positions of any two mounting holes 101 is the same), making the structure of the hanging device 100 regular and helping to improve the buffering and weakening effect of the rubber body 1 on the impact force in all directions.

[0036] It should be noted that in the hanging device 100, two of the three mounting holes 101 are arranged horizontally and are used to install and cooperate with the mounting structure (such as a hook) on the side of the vehicle body. The other mounting hole 101 is located in the area below the two mounting holes 101 in the vertical position and is used to install and cooperate with the mounting structure (such as a hook) on the side of the exhaust system. This allows the exhaust system to be suspended and arranged on the vehicle body, so that the exhaust system can avoid the mounting structure on the side of the vehicle body located above it. At the same time, the force between the exhaust system and the vehicle body can be absorbed and buffered by the rubber body 1.

[0037] Combination Figures 1-5 As shown, the connecting component 2 is provided with three connecting arms 21, and the three connecting arms 21 are connected and engaged. The "free end of the connecting arm 21" refers to the end of each connecting arm 21 that is away from the end of the connecting arm 21 that is connected and engaged with the other connecting arms 21. A connecting part 214 is formed at the free end of the connecting arm 21. The connecting part 214 is used to engage with the rubber body 1 to realize the connection and engagement between the connecting component 2 and the rubber body 1.

[0038] Furthermore, the rubber body 1 and the connecting component 2 are connected and engaged by a three-section connecting arm 21. Since the three-section connecting arm 21 is Y-shaped, the three connecting parts 214 in the connecting component 2 are arranged at intervals in the circumferential direction around the connection engagement area of ​​the three-section connecting arm 21, so that there are multiple connection positions between the connecting component 2 and the rubber body 1. The connecting component 2 can apply tension to the connection engagement area of ​​the three-section connecting arm 21 through multiple connection positions, thereby avoiding excessive stretching of the rubber body 1.

[0039] It is understood that when the exhaust system is suspended on the vehicle body by the suspension device 100 of this application embodiment, the compression and stretching of the rubber body can effectively absorb the vibration of the exhaust component. The connecting component 2 can apply tension to the rubber body to avoid the problem of excessive stretching of the rubber body, thereby avoiding damage to the rubber body 1 due to excessive stretching. It can extend the service life of the rubber body 1 while ensuring the buffering function of the rubber body 1 against the vibration of the exhaust system.

[0040] According to the embodiment of the present application, the rubber body 1 of the hanging device 100 is assembled through three mounting holes 101, and the Y-shaped connecting component 2 can apply tension force to multiple positions of the rubber body 1 to avoid excessive stretching and cracking of the rubber body 1, thereby extending the service life of the rubber body 1 and ensuring the vibration absorption and buffering effect of the hanging device 100.

[0041] Combination Figure 1 and Figure 2 As shown, in some embodiments of this application, the rubber body 1 includes three rubber arms 11 connected end to end. Each rubber arm 11 has a mounting hole 101 at its end. The three rubber arms 11 surround each other to form a clearance hole 102 that runs through the first direction. The intersection area of ​​the three connecting arms 21 is located in the clearance hole 102.

[0042] It is understandable that each connecting arm 21 extends in a straight line, and thus the three connecting arms 21 are connected end to end to form a triangular rubber body 1, which makes the rubber body 1 structurally stable, helps to improve the structural strength of the rubber body 1, and reduces the risk of the rubber body 1 being damaged by excessive stretching or compression.

[0043] Reference Figure 1 and Figure 2As shown, one end of the connecting arm 21 has a mounting hole 101, and the end of the connecting arm 21 with the mounting hole 101 connects and engages with the end of another connecting arm 21 without the mounting hole 101, so that the three mounting holes 101 can be respectively arranged at the three vertices of the rubber body 1 arranged in a triangle. At the same time, the three connecting arms 21 surround to form a clearance hole 102. The clearance hole 102 is a hollow structure formed on the rubber body 1. When the rubber body 1 is compressed, the rubber arm 11 can be squeezed and deformed towards the clearance hole 102, so as to reserve space on the rubber body 1 for the rubber arm 11 to squeeze and deform, thereby improving the buffering effect of the rubber body 1 against the compressive force and reducing the risk of the rubber body 1 being damaged by excessive compression.

[0044] Furthermore, the connection mating area of ​​the three connecting arms 21 is located at the avoidance hole 102, thereby forming a space in the middle of the rubber body 1 suitable for avoiding the connection mating area of ​​the three connecting arms 21 in the connecting assembly 2, so that each connecting arm 21 can apply tension force to the central area of ​​the rubber body 1, improve the performance of the rubber body 1 in bearing tensile force, and facilitate the arrangement of the connecting assembly 2 in the rubber body 1.

[0045] In some embodiments of this application, the connecting component 2 is constructed as a strap, which includes the aforementioned multiple connecting arms 21, and each connecting arm 21 can be provided with a rubber arm 11, and a tension force is applied to the rubber arm 11 towards the intersection of the three connecting arms 21 in the strap, so as to further improve the tensile strength of the rubber body 1 through the strap.

[0046] It should be noted that the connection and engagement method between the strap and the rubber body 1 is well known to those skilled in the art. For example, the strap passes through the through hole structure (e.g., the first through hole 1101) formed at the rubber arm 11 and is disposed at the clearance hole 102. After being divided into two sections at the clearance hole 102, the strap passes through the other two sections of the rubber arm 11 respectively. Furthermore, the portion of each strap (i.e., the connecting arm 21) placed on the outside of the rubber arm 11 (i.e., the side away from the clearance hole 102) can form a connecting portion 214 on the outside of the rubber arm 11, so that a tension force towards the center side can be applied to the rubber arm 11 through the connecting portion 214.

[0047] Combination Figure 1 and Figure 2 As shown, in some embodiments of this application, the hanging device 100 further includes a reinforcing frame 3, which is disposed on the side wall of each rubber arm 11 away from the avoidance hole 102, so as to improve the rigidity of the rubber body 1 by means of the reinforcing frame 3.

[0048] Understandably, the reinforcing frame 3 is positioned on the side of the rubber arm 11 away from the clearance hole 102, so that the reinforcing frame 3 is located on the circumferential outer side of the rubber body 1 and can avoid the clearance hole 102 to prevent interference between the reinforcing frame 3 and the connecting component 2. At the same time, the reinforcing frame 3 has a certain structural strength. After the reinforcing frame 3 is connected and fitted with the rubber body 1, the circumferential stiffness of the rubber body 1 can be improved by the reinforcing frame 3, so that the wall of the rubber body 1 is not excessively squeezed when the rubber body 1 is compressed.

[0049] Combination Figure 1 and Figure 2 As shown, the reinforcing frame 3 is tightly fitted to the outer peripheral wall of the rubber body 1, and the reinforcing frame 3 can be constructed as a metal part and further fixed to the rubber body 1 by vulcanization, thereby improving the reliability of the fit between the reinforcing frame 3 and the rubber body 1, which helps to improve the compressibility of the hanging device 100.

[0050] It is understandable that when the rubber body 1 is compressed, the reinforcing frame 3 can also deform along with the rubber body 1. Furthermore, the reinforcing frame 3 has a certain elasticity, which gives the deformed reinforcing frame 3 a tendency to return to its original position. This increases the overall compression of the hanging device 100 by reinforcing the frame 3, which not only provides a good buffering effect against vibration or impact but also prevents the hanging device 100 from being over-compressed, thus helping to extend the service life of the rubber body 1.

[0051] Combination Figure 1 and Figure 2 As shown, in some embodiments of this application, the rubber arm 11 is provided with a first through hole 1101, the reinforcing frame 3 is provided with a second through hole 301, and the first through hole 1101 and the second through hole 301 are arranged opposite to each other. The connecting arm 21 is arranged to pass through the rubber arm 11 and the reinforcing frame 3 in sequence through the first through hole 1101 and the second through hole 301, and the connecting arm 21 applies a tensioning force to the reinforcing frame 3 to move closer to one side of the rubber arm 11.

[0052] Understandably, the first through hole 1101 and the second through hole 301 are used for the connecting arm 21 to pass through, so that each connecting arm 21 can pass through the clearance hole 102 to the outside of the rubber body 1 and the reinforcing frame 3, and the connecting part 214 is placed on the side wall of the reinforcing frame 3 away from the rubber arm 11, so that the connecting arm 21 can apply a tension force to the reinforcing frame 3 towards the center area of ​​the rubber body 1 through the connecting part 214, thereby preventing the rubber body 1 from being overstretched.

[0053] Meanwhile, the reinforcing frame 3 is located on the outer circumferential side of the rubber body 1, and the connecting component 2 can tightly fit the reinforcing frame 3 with the rubber body 1, so that the force generated by the deformation of the rubber body 1 can also be fed back to the reinforcing frame 3. Since the reinforcing frame 3 has a certain rigidity, and the reinforcing frame 3 is fixedly fitted with the rubber body 1 through the connecting component 2, it can improve the rigidity of the rubber body 1 in the circumferential direction, thereby effectively limiting excessive stretching or compression of the rubber body 1 and helping to extend the service life of the rubber body 1.

[0054] Combination Figure 1 and Figure 2 As shown in a further embodiment of this application, the connecting portion 214 of each connecting arm 21 is constructed as a limiting flange. The limiting flange abuts against the side wall of the reinforcing frame 3 away from the rubber arm 11, so that the connecting arm 21 can apply tension force to the reinforcing frame 3 through the limiting flange, so that the reinforcing frame 3 can maintain a tight fit with the wall of the rubber body 1.

[0055] Furthermore, the area of ​​the limiting flange is larger than the opening area of ​​the second through hole 301, so that at least part of the limiting flange protrudes outward in the circumferential direction of the second through hole 301, so as to ensure that the limiting flange can abut against the side wall of the reinforcing frame 3 away from the rubber arm 11.

[0056] Combination Figure 1 and Figure 2 As shown, in some embodiments of this application, in the projection in the first direction, the outer peripheral wall of the head 111 of each rubber arm 11 with the mounting hole 101 extends in an arc shape, so that the shape of the head 111 of the rubber arm 11 with the mounting hole 101 matches the shape of the mounting hole 101. At the same time, the head 111 of the rubber arm 11 is provided on the side opposite to the avoidance hole 102, protruding from the main body of the rubber arm 11.

[0057] Furthermore, there are three reinforcing frames 3, and each reinforcing frame 3 includes a main connecting section 31 and two arc-shaped connecting sections 32. The main connecting section 31 is fitted to the side wall of the rubber arm 11 away from the avoidance hole 102, and the main connecting section 31 is located between the heads 111 of the two rubber arms 11. The two arc-shaped connecting sections 32 are respectively connected to the two ends of the main connecting section 31, and each arc-shaped connecting section 32 is fitted to a portion of the outer peripheral wall of the head 111. Thus, the fitted arrangement of the reinforcing frames 3 and the rubber body 1 helps to increase the contact area between each reinforcing frame 3 and each rubber arm 11, so that the reinforcing frames 3 can improve the stiffness of the rubber body 1 near the outer peripheral wall area.

[0058] Combination Figure 1 and Figure 2As shown in some embodiments of this application, the suspension device 100 is provided with three reinforcing frames 3, which are respectively connected and cooperate with three rubber arm segments 11. The three reinforcing frames 3 provide reinforced support to the three rubber arm segments 11. Furthermore, the three reinforcing frames 3 are relatively independent and elastic, allowing them to limit the deformation of the rubber body 1. Compared to a method where the entire frame is enclosed on the circumferential outer side of the rubber body 1, this avoids excessive overall stiffness of the suspension device 100. Therefore, the suspension device 100 can effectively buffer the impact and vibration between the exhaust system and the vehicle body.

[0059] Combination Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of this application, the rubber body 1 includes two rubber arms 11 arranged in a V-shape, one of the three mounting holes 101 is located at the connection of the two rubber arms 11, and the other two mounting holes 101 are respectively located at the free ends of the two rubber arms 11, such that the three mounting holes 101 are arranged at the apex corner of the rubber body 1 arranged in a V-shape.

[0060] Understandably, the rubber body 1 is used to assemble the exhaust system on the vehicle body. Two mounting holes 101 at the opening of the V-shaped rubber body 1 are used to connect and mate with mounting structures (such as hooks) on the vehicle body. The mounting holes 101 at the bottom of the V-shaped rubber body 1 (i.e., the connection point of the two rubber arms 11) are used to connect and mate with mounting structures (such as hooks) at the exhaust system. The V-shaped rubber body 1 has high structural strength and good stability, which helps to improve the buffering effect of the rubber body 1 against vibration and impact.

[0061] Combination Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of this application, the connecting portion 214 of each connecting arm 21 is constructed to extend in an arc shape. The connecting portion 214 is embedded in the rubber body 1 and is located on the circumferential outer side of the mounting hole 101. Moreover, the connecting portion 214 surrounds part of the mounting hole 101 in the circumferential direction, thereby realizing the connection and engagement between the connecting portion 214 and the rubber body 1, and connecting and fixing the connecting component 2 and the rubber body 1.

[0062] It is understood that the connecting portion 214 is embedded in the rubber body 1 and is located on the axial outer side of the mounting hole 101, so as to further enhance the structural strength at the mounting hole 101. The arc-shaped inner wall of the connecting portion 214 and the hole wall of the mounting hole 101 are spaced apart in the radial direction of the mounting hole 101 to prevent interference between the connecting portion 214 and the mounting hole 101.

[0063] Furthermore, each connecting portion 214 only surrounds the mounting hole 101 in the circumferential direction, thereby preventing the mounting hole 101 from being a separate rubber block portion from the rubber body 1, ensuring that the rubber body 1 is integrally formed. In other words, the rubber portion that encloses and defines the mounting hole 101 is part of the rubber arm 11.

[0064] In some embodiments of this application, the arc-shaped connection structure formed at the connecting part 214 is an optimal arc, which can increase the contact area and ensure the reliability of the connection between the connecting part 214 and the rubber body 1.

[0065] Preferably, the arc-shaped opening of each connecting part 214 extending in an arc shape is open towards the connection intersection area of ​​the three connecting arms 21, which helps to ensure the reliability of the connection between the connecting part 214 and the rubber body 1.

[0066] Combination Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of this application, the three mounting holes 101 are respectively the first mounting hole 1011, the second mounting hole 1012 and the third mounting hole 1013. The first mounting hole 1011 and the second mounting hole 1012 are respectively formed at the free ends of the two rubber arms 11, and the third mounting hole 1013 is formed at the connection of the two rubber arms 11.

[0067] Furthermore, the three connecting arms 21 are respectively the first connecting arm 211, the second connecting arm 212, and the third connecting arm 213. The first connecting arm 211 and the second connecting arm 212 are connected to each other, and the first connecting arm 211 and the second connecting arm 212 are connected at the open ends of the two rubber arms 11 arranged in a V shape. The third connecting arm 213 is connected between the connection area of ​​the first connecting arm 211 and the second connecting arm 212 and the connection point of the two rubber arms 11.

[0068] Therefore, the first connecting arm 211 and the second connecting arm 212 can apply a tightening force to the free ends of the two rubber arms 11, bringing them closer together, to maintain the structural stability and reliability of the rubber body 1. At the same time, the third connecting arm 213 can connect and support the connection between the two rubber arms 11 and the connection between the two connecting arms 21 (i.e., the first connecting arm 211 and the second connecting arm 212), further improving the anti-deformation performance of the hanging device 100 and its buffering and absorption effect against impact and vibration.

[0069] Reference Figure 3 and Figure 4As shown, when the first connecting arm 211, the second connecting arm 212 and the two rubber arms 11 are connected and engaged, the first connecting arm 211, the second connecting arm 212 and the rubber body 1 form a triangle, which helps to improve the structural stability of the hanging device 100. In addition, the hollow center of the hanging device 100 can reduce the weight of the hanging device 100 and realize the lightweight design of the hanging device 100.

[0070] Furthermore, the triangular hollow area is further divided by the third connecting arm 213 to form two adjacent and smaller triangular hollow areas, which helps to further improve the structural stability of the hanging device 100, so that the hanging device 100 can play a good buffering role against impact and vibration, and reduce the risk of cracking of the rubber body 1 due to excessive deformation (such as excessive stretching or compression).

[0071] Combination Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of this application, the first connecting arm 211 includes a first arm body 2111, one end of which is connected to the free end of a rubber arm 11 via a connecting portion 214, and the first arm body 2111 extends in an arc shape; the second connecting arm 212 includes a second arm body 2121, one end of which is connected to the free end of another rubber arm 11, and the second arm body 2121 extends in an arc shape, the other end of which is connected to the other end of the first arm body 2111 and smoothly transitions to form an arc-shaped segment that opens away from the third mounting hole 1013, so that the first connecting arm 211 and the second connecting arm 212 can be elastically connected and supported between the free ends of the two rubber arms 11.

[0072] It is understandable that the first arm body 2111 and the second arm body 2121 appear in an arc shape, so that the part of the first connecting arm 211 and the second connecting arm 212 located between the two rubber arms 11 extends in an arc shape, which helps to increase the elasticity of the connecting component 2, so that the first connecting arm 211 and the second connecting arm 212 can provide good elastic support between the two rubber arms 11.

[0073] In a further embodiment of this application, the first connecting arm 211 and the second connecting arm 212 are integrally formed, thereby ensuring the consistency and structural strength of the first connecting arm 211 and the second connecting arm 212, improving the elastic performance of the first connecting arm 211 and the second connecting arm 212, and enabling the first connecting arm 211 and the second connecting arm 212 to be elastically connected and supported between the free ends of the two rubber arms 11.

[0074] In some embodiments of this application, the third connecting arm 213 includes a third arm body 2131, one end of which is connected to the connection point of the two rubber arms 11 via a connecting part 214, thereby realizing the connection and cooperation between the third connecting arm 213 and the rubber body 1.

[0075] Furthermore, the connecting assembly 2 also includes: a first connecting piece 215 and a second connecting piece 216. The first connecting piece 215 extends in an arc shape, and the arc-shaped opening of the first connecting piece 215 is open towards one of the rubber arms 11. The first connecting piece 215 is connected between the other end of the first arm body 2111 and the third arm body 2131. The second connecting piece 216 extends in an arc shape, and the arc-shaped opening of the second connecting piece 216 is open towards the other rubber arm 11. The second connecting piece 216 is connected between the other end of the second arm body 2121 and the third arm body 2131.

[0076] Therefore, the third connecting arm 213 can be connected and cooperated with the first arm body 2111 through the first connecting piece 215 and with the second arm body 2121 through the second connecting piece 216. This increases the connection and cooperation area between the third connecting arm 213 and the first arm body 2111 and the second arm body 2121. Furthermore, the first connecting piece 215, the second connecting piece 216, the first arm body 2111 and the second arm body 2121 further enclose and form a triangular space. This area has good structural stability, which helps to improve the reliability of the connection and cooperation between the third connecting arm 213 and the first connecting arm 211 and the second connecting arm 212.

[0077] Meanwhile, a triangular region is formed by the first connecting arm 211, the third connecting arm 213, and a section of rubber arm 11; a triangular region is also formed by the second connecting arm 212, the third connecting arm 213, and another section of rubber arm 11. This improves the structural stability of the suspension device 100.

[0078] In some embodiments of this application, the thickness of the connecting arm 21 is 0.5mm-1mm, which enables the connecting arm 21 to have good elastic properties. The connecting arm 21 can be constructed as a stainless steel elastic plate.

[0079] The hanging device 100 according to the embodiments of this application has at least the following advantages: (1) When the connecting component 2 is constructed as a metal plate (e.g., stainless steel elastic steel plate), the elastic buffer of the rubber body 1 can be compensated by the connecting component 2, and the excessive stretching and compression of the rubber body 1 can be avoided, reducing the risk of the rubber body 1 breaking due to aging, thereby extending the service life of the hanging device 100. (2) A reinforcing frame 3 is provided on the outer side of the rubber body 1. Multiple reinforcing frames 3 are arranged around the rubber body 1 at intervals, and the multiple reinforcing frames 3 are independent of each other. The rigidity of the rubber body 1 can be improved by reinforcing frames 3, and the excessive expansion and contraction of the rubber body 1 can be effectively limited, which helps to extend the service life of the hanging device 100.

[0081] The vehicle has a body and an exhaust system mounted on the body, and the suspension device 100 is used to suspend and assemble the exhaust system on the vehicle body.
