Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a hanging device, an exhaust system assembly with the hanging device and a vehicle. BACKGROUND

[0002] As an important modern means of transportation, automobiles come in a variety of types, including sedans, SUVs, MPVs, trucks, buses and other types. Although different types of automobiles have different purposes and design features, they all have high requirements for comfort. As an indispensable part of automobiles, the exhaust system not only undertakes the key task of discharging exhaust gas, but also directly affects the comfort and stability of the vehicle. The rubber hanging of the exhaust system, as a key component connecting the exhaust system and the vehicle body frame, plays an important role in ensuring the normal operation of the exhaust system and improving the comfort of the vehicle.

[0003] Currently, there are two common types of connection methods for the rubber hanging of the automobile exhaust system. The first type is a hanging device composed of only a rubber block, and the connection method is to connect both ends of the exhaust hook through the same rubber hanging. This structure is relatively simple and can meet the connection requirements of the exhaust system to some extent. The second type is to vulcanize a metal frame around the rubber block, and the metal frame is connected to the vehicle body or frame by bolts. This rubber hanging structure with a metal frame enhances the stability of the connection to some extent and avoids the problem of aging and cracking of the rubber block alone.

[0004] However, both of the above-mentioned common rubber hanging methods of the exhaust system have deficiencies. For the hanging device composed of only a rubber block, due to the characteristics of the rubber material, it is prone to aging during long-term use. After aging, the strength and toughness of the rubber block decrease, and it is prone to cracking, thereby affecting the normal operation of the exhaust system. For the rubber hanging with a metal frame around it, although the metal frame improves the stability of the connection, the limiting effect of the metal frame greatly increases the overall stiffness of the rubber hanging. This change seriously affects the original buffering and vibration absorption effect of the rubber hanging, thereby reducing the comfort of the vehicle and failing to meet the requirements of the automobile for comfort and stability.

[0006] Therefore, the present application aims to provide a hanging device, an exhaust system assembly with the hanging device and a vehicle, by improving the structure of the hanging device, so that the hanging device has good buffering effect and long service life.

[0007] To achieve the above object, the first aspect of the present application provides a hanging device for connecting a vehicle body and an exhaust pipe, the hanging device comprising a buffer and a rigid support; the buffer is elastically deformable to buffer the vibration transmitted from the exhaust pipe to the vehicle body, the buffer comprises a first buffer part and a second buffer part, one end of the first buffer part and the second buffer part is connected to each other, and the first buffer part and the second buffer part are arranged at an included angle; the rigid support is attached to the buffer to support the buffer.

[0008] In the above technical solution, the first buffer part and the second buffer part of the buffer are connected at one end and arranged at an included angle, the first buffer part and the second buffer part can deform relatively, this unique structural design makes the buffer itself have good elastic deformation ability, and the buffer with this structure makes the rigid support attached thereto also have certain deformation ability, so that the rigid support can not only provide necessary support to the buffer, but also adapt to the deformation of the buffer, so that the whole hanging device can effectively buffer and absorb the vibration of the exhaust pipe, reduce the vibration transmitted to the vehicle body, and improve the comfort of the vehicle; at the same time, due to the support of the rigid support, the hanging device also has high strength and durability, prolonging the service life.

[0043] In the following, the utility model is specifically described by exemplary embodiments.However, it should be understood that the elements, structures and features in one embodiment can also be beneficially combined into other embodiments without further description.

[0044] The automobile exhaust system hanging device is used for connecting the exhaust system and the vehicle body frame, the hanging device bears the gravity of the exhaust system, and also has the functions of limiting, buffering and absorbing the vibration of the exhaust system, thereby improving the comfort of the whole vehicle.

[0045] In the prior art, there are two kinds of hanging devices for exhaust systems: the first kind of hanging device is only composed of a rubber hanging block, and both ends of the exhaust hanging hook are connected through the same rubber hanging block; the second kind of hanging device is provided with a metal frame around the rubber hanging block, and the metal frame is connected to the vehicle body or frame by bolts.

[0046] However, the first kind of hanging device is only composed of a rubber block, which is prone to aging after long-term use, and the aged rubber block has a risk of breaking, affecting the normal work of the exhaust system. The second kind of hanging device is provided with a metal frame around the rubber hanging block, and the rigidity of the whole hanging device changes a lot due to the limiting effect of the metal frame, thereby affecting the buffering effect and the effect of absorbing the vibration of the exhaust system.

[0047] Based on this, the first aspect of the present application provides a kind of hanging device, the hanging device includes buffer and rigid support, buffer is used to buffer the vibration of exhaust system, rigid support is used to provide support for buffer, by improving the shape structure of buffer, so that the whole hanging device has certain deformation performance, it has higher strength simultaneously, effectively solve the problem that rubber hanging is prone to breaking after aging and setting metal frame leads to the rigidity of the whole hanging device to be big, good buffering effect and longer service life are considered.

[0048] In the following, the embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0049] As Figures 1-4 As shown in one illustrative embodiment of the hanging device of the present application, the hanging device 1 includes a buffer 11 and a rigid support 12.

[0050] The buffer 11 can be elastically deformed to buffer the vibration transmitted by the exhaust pipe to the vehicle body. The buffer 11 includes a first buffer portion 111 and a second buffer portion 112, one end of the first buffer portion 111 and the second buffer portion 112 are connected to each other, and the first buffer portion 111 and the second buffer portion 112 are arranged at an included angle.

[0051] The rigid support 12 is attached to the buffer 11 to support the buffer.

[0052] The hanging device 1 provided by the present application improves the structure of the buffer 11, which includes the first buffer portion 111 and the second buffer portion 112 arranged at an included angle, and the first buffer portion 111 and the second buffer portion 112 can deform relative to each other. This structural design endows the buffer 11 with good elastic deformation capability, so that it can efficiently absorb and disperse vibration energy when subjected to the vibration of the exhaust pipe, thereby significantly reducing the transmission of vibration to the vehicle body and improving the comfort of the vehicle.

[0053] In addition, the rigid support 12 is attached to the buffer 11 with the above structure, further optimizing the performance of the hanging device 1. Based on the above structural design of the buffer 11, the rigid support 12 has a certain deformation ability to adapt to the buffer 11, so that it can cooperate with the elastic deformation of the buffer 11. When the exhaust pipe vibrates, the buffer 11 elastically deforms, and the rigid support 12 deforms to adapt to the change, avoiding the stress concentration problem caused by rigid constraint. The mutual cooperation of the rigid support 12 and the buffer 11 in the deformation process enhances the overall deformation ability and buffering effect of the hanging device 1.

[0054] Furthermore, the rigid support 12 is added to provide structural support and protection for the buffer 11, dispersing the direct impact of vibration energy on the buffer, prolonging the service life of the buffer. At the same time, the high strength and durability of the rigid support 12 further improve the overall strength and reliability of the hanging device 1, so that it can work stably for a long time, and will not be easily damaged even in complex working conditions.

[0055] The hanging device 1 of the present application realizes the effects of efficient buffering, vibration reduction, enhanced durability and prolonged service life through the structural design of the buffer 11 and the cooperation of the rigid support 12, so that when the hanging device 1 is applied to the exhaust system for hoisting the exhaust pipe, it can better play the buffering effect and has a longer service life, providing a strong guarantee for the reliability and safety of the vehicle.

[0056] The attachment position and attachment method of the rigid support 12 are not limited in the present application, as long as it can play a supporting role for the buffer 11. For example, the rigid support 12 can be attached to part or all of the side wall surface of the first buffer part 111, or attached to part or all of the side wall surface of the second buffer part 112, or attached to the entire side wall surface of the buffer 11.

[0057] In addition, the rigid support 12 can be in full contact with the side wall surface of the buffer 11, or in partial contact with the outer wall surface of the buffer 11, as long as it can be connected with the buffer 11 and play a supporting role. When the rigid support 12 is in partial contact with the side wall of the buffer 11, the part not in contact with the buffer 11 can avoid the constraint effect on the elastic deformation of the buffer 11, thereby enhancing the deformation ability of the hanging device 1.

[0058] It can be understood that the rigid support usually has a thin thickness, so as to reduce the weight of the hanging device 1 and reduce the cost as much as possible on the premise of providing necessary support and protection for the buffer. When the rigid support is attached to the buffer with a V-shaped structure, it itself has a certain deformation ability due to the shape of the buffer. This deformation ability can work with the buffer when the buffer is elastically deformed, so as to avoid significantly reducing the buffering effect of the buffer due to rigid collision or excessive constraint. Therefore, the rigid support can adapt to the deformation of the buffer while providing support, further optimizing the overall performance of the hanging device 1, and achieving a good balance between absorbing vibration, reducing weight and reducing cost.

[0059] In some embodiments, the first buffer part 111 and the second buffer part 112 constitute a V-shaped structure.

[0060] In the above technical solution, the first buffer part 111 and the second buffer part 112 constitute a V-shaped structure, so that the buffer 11 as a whole forms a stable mechanical structure. When subjected to external force, the first buffer part 111 and the second buffer part 112 as two sides of the V-shaped structure can deform in two directions respectively, providing a larger deformation space for realizing vibration absorption effect. In addition, the external stress is also dispersed through the geometric characteristics of the V-shaped structure angle, avoiding the phenomenon of stress concentration. In addition, the rigid support 12 is attached to the buffer 11 of the V-shaped structure, so that the deformation of the rigid support 12 itself can adapt to the elastic deformation of the buffer 11 to a certain extent, so that the two can better play a synergistic effect, can efficiently absorb and disperse vibration energy, and at the same time maintain the stability of the structure.

[0061] In some embodiments, as shown in Figure 3 and Figure 4 The end of the first buffer part 111 away from the second buffer part 112 is a first connecting end 113, the end of the second buffer part 112 away from the first buffer part 111 is a second connecting end 114, and the end of the first buffer part 111 and the second buffer part 112 connected to each other is a third connecting end 115. Two of the first connecting end 113, the second connecting end 114 and the third connecting end 115 are connected to the vehicle body, and one is connected to the exhaust pipe, so as to hang the exhaust pipe in the vehicle body.

[0062] In the above embodiment, the buffer 11 has three connection ends, two of which are used to connect with the vehicle body, and the other is connected with the exhaust pipe. This unique three-end connection structure realizes the double connection between the exhaust pipe and the vehicle body, and the exhaust pipe is indirectly connected with the vehicle body through two different connection ends. This connection method significantly improves the lifting reliability of the exhaust pipe, even if one of the connection ends is accidentally detached, the exhaust pipe can still be connected with the vehicle body through the other connection end, thereby avoiding the risk of the exhaust pipe falling directly. This double safety mechanism effectively enhances the stability of the exhaust pipe during vehicle driving, reduces the safety hazards caused by connection failure, makes the lifting connection of the exhaust pipe more stable and reliable, and provides a strong guarantee for the safe operation of the vehicle.

[0063] Considering the stress conditions of different hanging modes of the exhaust pipe, preferably, the first connection end 113 and the second connection end 114 are used to connect the vehicle body, and the third connection end 115 is used to connect the exhaust pipe. Such a connection method makes the first buffer part 111 and the second buffer part 112 form two cantilevers for hanging the exhaust pipe, thereby forming a connection mode of hanging the exhaust pipe from both sides. This hanging mode has a certain stability and has excellent effect on left and right limiting of the exhaust pipe, can constrain the transverse vibration, and improve the stability of the exhaust system.

[0064] It can be understood that the above hanging mode of connecting the vehicle body through the first connection end 113 and the second connection end 114 and connecting the exhaust pipe through the third connection end 115 is only one of the more reasonable ways, but it does not exclude that different ways are used for connection by those skilled in the art for other purposes. For example, in some embodiments, the first connection end 113 and the third connection end 115 are used to connect the vehicle body, and the second connection end 114 is used to connect the exhaust pipe, or the second connection end 114 and the third connection end 115 are used to connect the vehicle body, and the first connection end 113 is used to connect the exhaust pipe. These connection methods can also lift the exhaust pipe in the vehicle body, but may cause the lifting reliability to be reduced due to unbalanced stress.

[0065] In some embodiments, as shown in Figure 3 The included angle α between the first buffer part 111 and the second buffer part 112 is formed, and the angle bisector of the included angle α is located in the vertical direction.

[0066] In the above embodiment, by limiting the position of the angle bisector of the included angle a between the first buffer part 111 and the second buffer part 112, the included angle between the first buffer part 111 and the second buffer part 112 and the vertical direction is the same, so that the exhaust pipe is kept in a relatively stable position during hanging, improving the stability of the hanging connection. Especially in the case where the first connecting end 113 and the second connecting end 114 are connected to the vehicle body, and the third connecting end 115 is connected to the exhaust pipe, the force borne by the buffer piece 11 can be more evenly distributed, making the deformation of the buffer piece more uniform and reducing stress concentration. In this application, the "included angle a" does not include the case of 180°, that is, the length direction of the first buffer part 111 and the length direction of the second buffer part 112 are not on the same straight line.

[0067] It should be noted that in the above embodiment, the hanging device 1 does not need to be distinguished between up and down when in use, and can be installed according to the needs of vehicle body design. For example, in actual installation, the first connecting end 113 and the second connecting end 114 can be located above the third connecting end 115, at which time the hanging device 1 is arranged in a positive V shape; in another case, the first connecting end 113 and the second connecting end 114 can also be located below the third connecting end 115, at which time the hanging device 1 is arranged in an inverted V shape.

[0068] It can be understood that when the buffer piece 11 has a V-shaped structure, it itself is mirror-symmetrically distributed relative to the angle bisector of the included angle a, so that the exhaust pipe hanging at the intersection of the V-shaped structure is in a force balance position, achieving better positioning effect on the exhaust pipe, and the first buffer part 111 and the second buffer part 112 uniformly bear the force transmitted by the exhaust pipe in two directions, so that the stress of the hanging device 1 is more uniform, avoiding the case where one side bears too much force and the other side bears too little force, effectively reducing the local overload condition, prolonging the service life of the hanging device 1, improving the stability of the hanging device 1, and reducing the vibration transmitted to the vehicle body.

[0069] In some embodiments, the rigid support 12 is mirror-symmetrically arranged relative to the angle bisector of the included angle a. Such a design makes the deformation ability of the hanging device 1 symmetrically distributed relative to the hanging position, and the stress and deformation degree on both sides are more consistent under external force, which can ensure that the hanging device 1 can uniformly buffer and absorb external force, so that the stress can be symmetrically conducted and dispersed on both sides, reducing the phenomenon of stress concentration, reducing the risk of fatigue cracks or damage of the structure due to stress concentration, and improving the reliability of the overall structure.

[0070] In some embodiments, as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the rigid support 12 is arranged around the buffer 11, and the rigid support 12 is not closed in the circumferential direction to form an opening part 121.

[0071] In the above embodiment, by virtue of the opening design of the rigid support 12, the constraint of the rigid support 12 on the buffer 11 in the entire circumferential direction is avoided, additional space is provided for the elastic deformation of the buffer, the deformation capability of the hanger device 1 is further enhanced, the rigidity coefficient of the hanger device 1 is reduced, the influence of the rigid support on the buffering and vibration absorption of the exhaust system by the hanger device 1 is reduced, the vibration transmitted to the vehicle body is reduced, and the comfort of the vehicle is improved.

[0072] In the present application, the opening position and the number of the opening of the rigid support 12 are not limited. In actual application, the design can be made according to the overall requirements of the hanger device 1 and in combination with the structure and shape of the buffer 11. For example, the rigid support 12 is arranged around the side wall of the buffer 11, the opening part 121 can be formed on the side wall at the first buffer part 111, or the side wall at the second buffer part 112; or the opening part 121 has a plurality of opening parts 121 distributed on the side wall at the first buffer part 111 and the second buffer part 112.

[0073] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 5 and Figure 6 , the rigid support 12 comprises a main body segment 122 and first and second hook-shaped segments 123 and 124 located at both ends of the main body segment 122; the main body segment 122 is attached to the outer wall of the third connecting end 115; the first hook-shaped segment 123 is connected to the main body segment 122 and is attached to the side of the first buffer part 111 close to the second buffer part 112 after bypassing the first connecting end 113; the second hook-shaped segment 124 is connected to the main body segment 122 and is attached to the side of the second buffer part 112 close to the first buffer part 111 after bypassing the second connecting end 114.

[0074] In the above embodiment, the rigid support 12 is attached to the side away from the included angle of the V-shaped structure and extends from both ends to the inside of the included angle of the V-shaped structure, which cooperates with the structure design of the buffer 11, the rigid support 12 is attached to the position where the deformation capability of the buffer 11 is the largest, that is, the position where fatigue fracture is most likely to occur, which provides support and protection for the structure of the buffer 11, enhances the strength of the hanger device 1, avoids problems such as fracture due to excessive deformation of the buffer 11, and makes the hanger device 1 maintain a relatively stable shape, thereby prolonging the service life of the hanger device 1.

[0075] Moreover, the opening part 121 of the rigid support 12 is between the first hook-shaped section 123 and the second hook-shaped section 124, and the opening part 121 is continuously formed on the surface between the first buffer part 111 and the second buffer part 112, which is the position with the largest deformation capacity of the buffer 11. The opening part 121 formed at this position can further reduce the influence of the rigid support 12 on the deformation capacity of the buffer 11, so that the buffer 11 still has a certain deformation space when vibrating, optimizes the vibration damping effect, and effectively reduces the vibration transmitted to the vehicle body.

[0076] In addition, the first hook-shaped section 123 and the second hook-shaped section 124 at both ends of the rigid support 12 have a structure similar to a hook, and the first hook-shaped section 123 and the second hook-shaped section 124 surround the first connecting end 113 and the second connecting end 114, respectively, which can not only enhance the strength of the connecting end and improve the reliability of the connection, but also have a certain elastic deformation capacity, which can cooperate with the elastic deformation of the buffer 11, further reduce the rigidity coefficient of the whole hanging device 1, and improve the vibration absorption and buffering effect.

[0077] In some embodiments, the buffer 11 is connected with the rigid support 12 by vulcanization, so that a firm connection is formed between the two, which can ensure that the buffer 11 and the rigid support 12 will not easily separate under various working conditions, and improve the reliability of the hanging device 1.

[0078] In some embodiments, as shown in Figure 3 and Figure 4 , the side wall surface of the buffer 11 at the first connecting end 113, the second connecting end 114 and the third connecting end 115 protrudes outward to increase the size of the buffer 11 at the first connecting end 113, the second connecting end 114 and the third connecting end 115. In this embodiment, the size of the buffer 11 at the three connecting ends is increased by outward expansion, thereby increasing the strength of the three connecting ends, avoiding the situation that the connecting ends are broken after long-term use, and improving the reliability of the connecting position.

[0079] Based on the above embodiments, as shown in Figure 5 , the position where the rigid support 12 is attached to the first connecting end 113, the second connecting end 114 and the third connecting end 115 also protrudes outward correspondingly to fit the outer wall surface of the buffer 11.

[0080] In some embodiments, as shown in Figure 3 and Figure 4As shown, the outer wall surface of the buffer 11 at the first connecting end 113, the second connecting end 114 and the third connecting end 115 is formed as a smooth surface. The smooth surface can avoid problems such as fatigue cracks at the connection position due to stress concentration, making the stress distribution more uniform, improving the overall strength and fatigue resistance, and extending the service life.

[0081] In some embodiments, such as Figures 1-4 As shown, mounting holes 116 are formed at the first connecting end 113, the second connecting end 114, and the third connecting end 115. The design of the mounting holes 116 facilitates the connection between the buffer 11 and the vehicle body and the exhaust pipe. For example, two hooks on the vehicle body side are inserted into the mounting holes 116 of the first connecting end 113 and the second connecting end 114, respectively, and one hook on the exhaust pipe side is inserted into the mounting hole 116 of the third connecting end 115, thereby connecting the exhaust pipe to the vehicle body. In addition, the three mounting holes 116 are arranged in a triangle, which provides a certain degree of stability and helps to limit the exhaust pipe and reduce vibration.

[0082] In some embodiments, the buffer 11 needs to have a certain degree of elasticity to achieve vibration absorption and buffering effects, and the buffer 11 can be made of rubber. Rubber materials have excellent elasticity and flexibility, and can effectively absorb and disperse vibration energy during vibration transmission, thereby significantly reducing the impact of vibration on the vehicle body.

[0083] In some embodiments, the rigid support 12 is specifically a metal component, such as one made of steel or aluminum alloy. Metal has high strength, which can improve the overall load-bearing capacity of the suspension device 1, so that the buffer 11 can maintain the structural integrity even when subjected to large external forces.

[0084] The suspension device 1 provided in this application improves the structure of the buffer 11 by including a first buffer portion 111 and a second buffer portion 112 arranged at an angle, thus giving the buffer 11 a V-shaped structure. This unique structural design gives the buffer 11 itself good elastic deformation capability. A rigid support 12 is attached to the buffer 11 with this structure, allowing the rigid support 12 to also have a certain deformation capability. Thus, while providing necessary support for the buffer 11, the rigid support 12 can also adapt to the deformation of the buffer 11. This allows the suspension device 1 as a whole to effectively buffer and absorb the vibration of the exhaust pipe, reducing the vibration transmitted to the vehicle body and improving vehicle comfort. At the same time, the suspension device 1 also has high strength and durability, avoiding the problem of aging and breakage that can occur with only the buffer 11, and extending its service life.

[0085] In a second aspect, the application further provides an exhaust system assembly, which comprises the exhaust pipe 2 and the hanger device 1 according to any one of the above embodiments; wherein one of the two ends of the first buffering part 111 and the second buffering part 112 away from each other, or the end of the first buffering part 111 and the second buffering part 112 connected to each other, is connected to the exhaust pipe 2.

[0086] In the above embodiments, the end of the first buffering part 111 away from the second buffering part 112 is the first connecting end 113, the end of the second buffering part 112 away from the first buffering part 111 is the second connecting end 114, and the end of the first buffering part 111 and the second buffering part 112 connected to each other is the third connecting end 115; one of the first connecting end 113, the second connecting end 114 and the third connecting end 115 is connected to the exhaust pipe 2.

[0087] The exhaust system assembly provided by the application can effectively absorb the vibration of the exhaust pipe 2 when the exhaust pipe 2 vibrates, avoid the transmission to the vehicle body, and affect the comfort and stability of the vehicle, and has a longer service life.

[0088] It can be understood that the exhaust system assembly may further include other components for assisting in achieving the exhaust function in addition to the exhaust pipe 2 and the hanger device 1, such as a catalytic converter, a muffler, and the like, which are not limited by the application.

[0089] In a third aspect, the application further provides a vehicle, which comprises a vehicle body and the exhaust system assembly described above; wherein two of the two ends of the first buffering part 111 and the second buffering part 112 of the hanger device 1 of the exhaust system assembly away from each other, and the end of the first buffering part 111 and the second buffering part 112 connected to each other are connected to the vehicle body, and the other is connected to the exhaust pipe 2, so as to hang the exhaust pipe 2 in the vehicle body. That is, two of the first connecting end 113, the second connecting end 114 and the third connecting end 115 are connected to the vehicle body, and the other is connected to the exhaust pipe 2.

[0090] In some embodiments, the first connecting end 113 and the second connecting end 114 are connected to the vehicle body, and the third connecting end 115 is connected to the exhaust pipe 2. Such a connection mode makes the first buffering part 111 and the second buffering part 112 form two cantilever arms for hanging the exhaust pipe, thereby forming a connection mode of hanging the exhaust pipe from both sides. Such a hanging mode has a certain stability and has an excellent effect on the left and right limiting of the exhaust pipe, can constrain the transverse vibration, and improve the stability of the exhaust system.

[0091] In some embodiments, as shown in FIG. 6, the first connecting end 113 and the second connecting end 114 are connected to the vehicle body, and the third connecting end 115 is connected to the exhaust pipe 2. Figures 7-9As shown, two body hooks 31 are fixed on the longitudinal beam 3 of the vehicle body, and one exhaust pipe hook 21 is fixed on the exhaust pipe 2, the two body hooks 31 are respectively inserted into the mounting holes 116 at the first connecting end 113 and the second connecting end 114 of the hanging device 1, and the exhaust pipe hook 21 is inserted into the mounting hole 116 at the third connecting end 115, so as to hang the exhaust pipe 2 in the vehicle body.

[0092] In the above embodiment, the hanging device 1 is installed in a positive V shape, the first buffer part 111 and the second buffer part 112 are connected to the longitudinal beam 3 of the vehicle body, and the exhaust pipe 2 is hung at the third connecting end 115 at the lower end, so as to form an installation mode of hanging the exhaust pipe 2 from both sides, which has excellent effect on limiting the left and right of the exhaust pipe 2, can constrain the transverse vibration, and improves the stability of the exhaust system.

[0093] It can be understood that the above hanging device 2 can also be installed in an inverted V shape in actual use, supports the exhaust pipe 2 at the top, and connects the first buffer part 111 and the second buffer part 112 at the lower end to the vehicle body, which has similar effect to the above positive V shape installation. The specific installation mode of the hanging device 1 depends on the installation position of the exhaust pipe 2 and the connection structure with the vehicle body, and the present application does not limit it.

[0094] In the above embodiment, the exhaust pipe 2 is connected to the longitudinal beam 3 of the vehicle body. However, in other embodiments, the body hooks 31 can also be fixed on other structures of the vehicle body, depending on the installation position and installation requirements of the exhaust pipe 2.

[0095] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limiting the present application, and those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present application.
