Abstract

This application discloses a suspension device and a vehicle, belonging to the field of vehicle shock absorption technology. The suspension device includes a main frame, an elastomer, and a limiting bracket. The main frame is used to connect to the vehicle body and has a mounting cavity. The elastomer is used to connect to the vehicle's powertrain and is disposed within the mounting cavity. In the vertical direction, a gap is formed between the elastomer with the powertrain and the main frame. The limiting bracket is connected to the main frame and includes a limiting part that is embedded in the gap. In the vertical direction, the limiting part and the elastomer are mutually limiting and engaging. In this design, embedding the limiting part of the limiting bracket in the gap fills the gap between the elastomer and the main frame in the vertical direction, making it easier and faster for the elastomer to absorb the impact force from the road surface. The limiting part and the elastomer mutually limiting and engaging ensure that the elastomer always maintains a relatively stable working state, preventing excessive stretching of the elastomer during long-term operation.

Description

Technical Field

[0001] This application belongs to the field of vehicle shock absorption technology, specifically relating to a suspension device and a vehicle. Background Technology

[0002] In the field of vehicle engineering, the suspension system, as a key component connecting the powertrain and the vehicle body, plays a crucial role in the overall performance of the vehicle. The core function of the suspension system is to improve the ride comfort and driving stability of the vehicle. By working in conjunction with the powertrain to form a vibration absorption system, it effectively absorbs vibrations transmitted from the road surface and suppresses powertrain swaying within the engine compartment, thereby ensuring that the vehicle maintains a smooth and stable driving state under various operating conditions.

[0003] In related technologies, common suspension devices mainly consist of a main frame connected to the vehicle body and an elastomer housed within the main frame. The elastomer is directly connected to the powertrain, serving to bear the weight of the powertrain and reduce its vibration. During actual assembly, after the suspension device and powertrain are assembled, the elastomer undergoes a certain degree of deformation under the weight of the powertrain. This deformation often results in a gap forming between the elastomer and the top of the main frame.

[0004] Because of the gap between the top of the elastomer and the main frame, the elastomer is prone to excessive stretching or shaking during vehicle operation. On the one hand, excessive stretching can lead to uneven stress distribution inside the elastomer, and long-term accumulation can cause a decrease in the elasticity of the elastomer, thereby reducing its buffering effect on the powertrain, resulting in increased vibration and noise during vehicle operation, and reducing driving and riding comfort. On the other hand, shaking can cause the connection between the elastomer and the main frame to loosen, aggravating wear between the two, and even causing the elastomer to detach from the main frame. Utility Model Content

[0005] The purpose of this application is to provide a suspension device and vehicle that can solve the problem in the related art that the elastomer is prone to excessive stretching or shaking during vehicle operation.

[0006] In a first aspect, embodiments of this application provide a suspension device, the suspension device comprising:

[0007] The main frame is used to connect with the vehicle body, and the main frame is provided with a mounting cavity;

[0008] An elastomer for connecting to the powertrain of the vehicle, the elastomer being disposed within the mounting cavity, and in the vertical direction, a gap is formed between the elastomer, to which the powertrain is mounted, and the main frame.

[0009] A limiting bracket is connected to the main frame. The limiting bracket includes a limiting part, which is embedded in the gap. In the vertical direction, the limiting part is matched with the elastic body for limiting.

[0010] The suspension device provided in this application embodiment includes a limiting bracket. After the powertrain and the elastomer are assembled, there is a gap between the elastomer and the main frame in the vertical direction. The limiting part of the limiting bracket is embedded in the gap, which can fill the gap between the elastomer and the main frame in the vertical direction. This allows the elastomer to absorb the impact force from the road surface more easily and quickly, which helps to reduce vehicle vibration and improve driving and riding comfort. At the same time, in the vertical direction, the limiting part and the elastomer limit each other, which can keep the elastomer in a relatively stable working state at all times, so as to prevent the elastomer from being overstretched during long-term operation, thereby extending the service life of the elastomer. It can also prevent the elastomer from shaking or shifting during operation, thereby improving the connection stability between the elastomer and the main frame and preventing the elastomer from falling off the main frame.

[0011] Optionally, the limiting bracket further includes a first connecting portion, which is connected to the limiting portion and is used to connect to the vehicle body. This configuration, on the one hand, can improve the stability of the limiting portion's fixation, further preventing the limiting portion from coming out of the gap; on the other hand, it can further improve the connection strength and stability between the suspension device and the vehicle body.

[0012] Optionally, the first connecting part is a plate-like structure, and an angle is formed between the first connecting part and the limiting surface of the limiting part. This arrangement facilitates the connection of the first connecting part to the vehicle body in a direction intersecting the vertical direction, thereby distributing the weight of the suspension device to the horizontal direction of the vehicle body.

[0013] Optionally, the limiting bracket further includes a second connecting portion, which is connected to the limiting portion and / or the first connecting portion. The second connecting portion is used to connect to the vehicle's overflow tank to support the overflow tank. This configuration improves the functionality of the suspension device.

[0014] Optionally, the limiting bracket further includes:

[0015] A first reinforcing plate is connected to the first connecting portion and the limiting portion respectively;

[0016] The second reinforcing plate is connected to both the first connecting part and the second connecting part.

[0017] This configuration can strengthen the first connecting part, the limiting part, and the second connecting part, and can improve the connection strength between the first connecting part and the limiting part, as well as the connection strength between the first connecting part and the second connecting part.

[0018] Optionally, the main frame is provided with an opening that communicates with the mounting cavity, and the main frame has a first side and a second side, which are located on both sides of the opening, respectively.

[0019] The limiting bracket further includes a third connecting part and a fourth connecting part. A portion of the third connecting part and a portion of the fourth connecting part are both connected to the limiting part. Another portion of the third connecting part passes through the opening and is connected to the first side. Another portion of the fourth connecting part passes through the opening and is connected to the second side.

[0020] This design allows portions of the third and fourth connecting parts to be exposed outside the mounting cavity, making it easier for operators to connect the third and fourth connecting parts to the first and second sides of the main frame, respectively. This facilitates operation and reduces the difficulty of installing the limiting bracket.

[0021] Optionally, in the direction from the first side to the second side, the width of the opening is greater than or equal to the width of the limiting part, and the limiting part can be inserted into the gap through the opening. This configuration allows the limiting part to be inserted into the gap through the opening when assembling the limiting bracket and the main frame, making assembly simple, convenient, and easy for operators to perform.

[0022] Optionally, in the direction from the first side to the second side, the width of the limiting portion is greater than the width of the opening. This configuration allows the limiting portion to engage with the main frame in the vertical direction, preventing the limiting portion from slipping out of the opening and thus improving the stability of the limiting portion.

[0023] Optionally, the third connecting part is connected to the first side part via a first fixing member, and the fourth connecting part is connected to the second side part via a second fixing member;

[0024] At least one of the first fastener and the second fastener is used to secure a cable connected to the powertrain.

[0025] This design effectively improves the functionality of the suspension system and eliminates the need for additional fasteners to secure cables, thus reducing the number of fasteners, simplifying the vehicle's structure, and reducing its weight.

[0026] Secondly, embodiments of this application also provide a vehicle, the vehicle including a body, a powertrain and any of the above-described suspension devices, the powertrain being connected to the elastomer of the suspension device, and the main frame of the suspension device being connected to the body.

[0027] The beneficial effects achieved by the vehicle provided in this application embodiment are the same as those achieved by the suspension device described above, and will not be repeated here. Attached Figure Description

[0040] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0041] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0042] The suspension device and vehicle provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0043] refer to Figures 1-4 The suspension device provided in this application embodiment may include a main frame 100, an elastic body 200 and a limiting bracket 400.

[0044] Among them, such as Figure 1 and Figure 2 As shown, the main frame 100 can be used to connect with the vehicle body, and the main frame 100 can be provided with a mounting cavity 120; the elastic body 200 can be used to connect with the vehicle's powertrain, and the elastic body 200 can be disposed within the mounting cavity 120. In this way, the main frame 100 and the elastic body 200 can achieve an elastic connection between the powertrain and the vehicle body.

[0045] In the vertical direction, a gap is formed between the elastic body 200, which is equipped with the power assembly, and the main frame 100. That is, after the elastic body 200 and the power assembly are assembled, the elastic body 200 deforms under the weight of the power assembly itself, thereby forming a gap between the elastic body 200 and the main frame 100 in the vertical direction.

[0046] like Figure 1 and Figure 2As shown, the limiting bracket 400 may include a limiting part 410, which can be embedded in the gap to fill the gap in the vertical direction between the elastic body 200 deformed under the gravity of the powertrain and the main frame 100. This allows the elastic body 200 to absorb the impact force from the road surface more easily and quickly, which helps to reduce the vibration of the vehicle body and thus effectively improve the comfort of driving and riding.

[0047] Here, the limiting bracket 400 can be connected to the main frame 100. This setting can prevent the limiting part 410 from coming out of the gap, which is beneficial to improving the limiting effect of the limiting part 410.

[0048] Furthermore, in the vertical direction, the limiting part 410 can engage with the elastic body 200 for limiting. This arrangement ensures that the elastic body 200 maintains a relatively stable working state, preventing excessive stretching of the elastic body 200 during prolonged operation, thereby extending the service life of the elastic body 200. It also prevents the elastic body 200 from shaking or shifting during operation, thus improving the connection stability between the elastic body 200 and the main frame 100 and preventing the elastic body 200 from detaching from the main frame 100.

[0049] It should be noted that the gap formed between the elastomer 200 equipped with the powertrain and the main frame 100 can be the gap between the top end of the elastomer 200 and the top wall of the mounting cavity 120, or the gap between the bottom end of the elastomer 200 and the bottom wall of the mounting cavity 120. When the gap formed between the elastomer 200 equipped with the powertrain and the main frame 100 is the gap between the top end of the elastomer 200 and the top wall of the mounting cavity 120, the limiting part 410 can be located above the elastomer 200; when the gap formed between the elastomer 200 equipped with the powertrain and the main frame 100 is the gap between the bottom end of the elastomer 200 and the bottom wall of the mounting cavity 120, the limiting part 410 can be located below the elastomer 200.

[0050] In this embodiment, the gap formed between the elastomer 200 equipped with the powertrain and the main frame 100 can be the gap between the top end of the elastomer 200 and the top wall of the mounting cavity 120, which facilitates the installation of the elastomer 200.

[0051] In optional embodiments of this application, such as Figure 1 , Figure 3 and Figure 4As shown, the limiting bracket 400 may further include a first connecting portion 420, which can be connected to the limiting portion 410 and can be used to connect to the vehicle body. In this embodiment, the suspension device can be connected to the vehicle body not only through the main frame 100 but also through the first connecting portion 420. This arrangement has two advantages: firstly, since the first connecting portion 420 is connected to the limiting portion 410 and the vehicle body, the first connecting portion 420 can provide a certain degree of fixation for the limiting portion 410, thereby improving the stability of the fixing of the limiting portion 410 and further preventing the limiting portion 410 from coming out of the gap; secondly, it can further improve the connection strength and stability between the suspension device and the vehicle body.

[0052] In other embodiments, the limiting bracket 400 may not include the first connecting portion 420. The suspension device may be connected to the vehicle body only through the main frame 100.

[0053] In optional embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the first connecting part 420 can be a plate-shaped structure, and an angle can be formed between the first connecting part 420 and the limiting surface of the limiting part 410. This arrangement facilitates the connection of the first connecting part 420 to the vehicle body in a direction intersecting with the vertical direction, thereby distributing the weight of the suspension device to the horizontal direction of the vehicle body.

[0054] For example, the angle between the first connecting portion 420 and the limiting surface of the limiting portion 410 can be 90°. This arrangement facilitates the horizontal connection between the first connecting portion 420 and the vehicle body. Of course, the angle between the first connecting portion 420 and the limiting surface of the limiting portion 410 can also be greater than 90° or less than 90°.

[0055] In other embodiments, the limiting surfaces of the first connecting portion 420 and the limiting portion 410 may not form an included angle. For example, the limiting surfaces of the first connecting portion 420 and the limiting portion 410 may be arranged parallel to each other.

[0056] Optionally, such as Figure 3 and Figure 4 As shown, the first connecting portion 420 can be connected to the limiting portion 410 via the intermediate connecting portion 460. The intermediate connecting portion 460 can be bent in the first direction a so that the first connecting portion 420 can avoid other components of the vehicle, such as the vehicle's overflow tank. Here, the first direction a can be perpendicular to the vertical direction and perpendicular to the direction from the elastomer 200 to the powertrain. It should be noted that the direction from the elastomer 200 to the powertrain can be as follows: Figure 4 The thickness direction c of the elastomer 200 shown.

[0057] In optional embodiments, such as Figures 1-3 As shown, the main frame 100 can be provided with two body connecting parts 110, each of which can be connected to the body. The two body connecting parts 110 can be located on both sides of the main frame 100 in the first direction a. This arrangement can improve the connection strength between the main frame 100 and the body.

[0058] Optionally, such as Figure 1 and Figure 3 As shown, the body connecting part 110 can be connected to the body via a first connecting bolt. Specifically, the body connecting part 110 is provided with a first connecting hole 111, which is arranged vertically. The first connecting bolt can pass through the first connecting hole 111 and be connected to the body. Here, the diameter of the head of the first connecting bolt is larger than the diameter of the first connecting hole 111. In this embodiment, the body connecting part 110 is connected to the body vertically. The first connecting part 420 can be connected to the body via a second connecting bolt, specifically, as shown... Figure 1 and Figure 3 As shown, a second connecting hole 421 is provided on the first connecting part 420. A second connecting bolt can pass through the second connecting hole 421 to connect with the vehicle body. Here, the diameter of the head of the second connecting bolt is larger than the diameter of the second connecting hole 421. Since there is an included angle between the limiting surface of the first connecting part 420 and the limiting part 410, the opening direction of the second connecting hole 421 can intersect with the vertical direction. This arrangement allows the connection direction between the first connecting part 420 and the vehicle body to intersect with the vertical direction, thereby distributing part of the force of the suspension device to the horizontal direction and preventing excessive force on the vehicle body in one direction.

[0059] In optional embodiments of this application, such as Figures 1-4 As shown, the limiting bracket 400 may further include a second connecting portion 430, which may be connected to the limiting portion 410 and / or the first connecting portion 420. The second connecting portion 430 may be used to connect to the vehicle's overflow tank to support the overflow tank. This configuration improves the functionality of the suspension device.

[0060] It's important to note that the overflow tank can be considered part of the vehicle's cooling system, used to regulate the flow and storage of antifreeze. Specifically, as the vehicle's engine temperature rises, the antifreeze expands beyond the radiator's capacity. The overflow tank then stores this excess antifreeze. After the vehicle stops, the antifreeze temperature gradually decreases, and the antifreeze stored in the overflow tank flows back into the radiator, ensuring a stable water level and guaranteeing smooth operation of the vehicle's cooling system.

[0061] In other embodiments, the limiting bracket 400 may also exclude the second connecting portion 430. For example, the overflow tank can be supported and fixed by other structures of the vehicle, such as a support plate provided on the vehicle body, which is connected to the overflow tank for supporting it.

[0062] Optionally, the second connecting part 430 can be connected to the overflow tank via a third connecting bolt, specifically, as shown in the example. Figure 1 and Figure 3 As shown, a third connecting hole 431 may be provided on the second connecting part 430. The third connecting bolt can pass through the third connecting hole 431 and connect to the overflow tank. Here, the diameter of the head of the third connecting bolt is larger than the diameter of the third connecting hole.

[0063] In an optional embodiment of this application, the limiting bracket 400 may further include a first reinforcing plate (not shown in the figure) and a second reinforcing plate (not shown in the figure). The first reinforcing plate may be connected to the first connecting portion 420 and the limiting portion 410, respectively. The second reinforcing plate may be connected to the first connecting portion 420 and the second connecting portion 430, respectively. In this embodiment, the first reinforcing plate can strengthen the first connecting portion 420 and the limiting portion 410, and can improve the connection strength between the first connecting portion 420 and the limiting portion 410. The second reinforcing plate can strengthen the first connecting portion 420 and the second connecting portion 430, and can improve the connection strength between the first connecting portion 420 and the second connecting portion 430.

[0064] Optionally, the limiting bracket 400 may include at least two first reinforcing plates and at least two second reinforcing plates. The first reinforcing plates may be distributed in parallel at intervals, and each first reinforcing plate may be connected to both the first connecting portion 420 and the limiting portion 410. Similarly, the second reinforcing plates may be distributed in parallel at intervals, and each second reinforcing plate may be connected to both the first connecting portion 420 and the second connecting portion 430. This configuration further enhances the connection strength between the first connecting portion 420 and the limiting portion 410, and further enhances the connection strength between the first connecting portion 420 and the second connecting portion 430.

[0065] In other embodiments, the limiting bracket 400 may also exclude the first reinforcing plate and the second reinforcing plate.

[0066] In optional embodiments of this application, such as Figure 3 As shown, the main frame 100 may be provided with an opening 130, which may communicate with the mounting cavity 120. The main frame 100 may have a first side 140 and a second side 150, which may be located on both sides of the opening 130 respectively.

[0067] like Figure 1As shown, the limiting bracket 400 may further include a third connecting portion 440 and a fourth connecting portion 450. A portion of the third connecting portion 440 and a portion of the fourth connecting portion 450 may be connected to the limiting portion 410. Another portion of the third connecting portion 440 may pass through the opening 130 and may be connected to the first side portion 140. Another portion of the fourth connecting portion 450 may pass through the opening 130 and may be connected to the second side portion 150.

[0068] In this embodiment, the opening 130 provided on the main frame 100 can provide channels for the third connecting part 440 and the fourth connecting part 450 to pass through and connect to the first side part 140 and the second side part 150 respectively. This allows parts of the third connecting part 440 and the fourth connecting part 450 to be exposed outside the mounting cavity 120, thereby facilitating the operator to connect the third connecting part 440 and the fourth connecting part 450 to the first side part 140 and the second side part 150 of the main frame 100 respectively, making the operation convenient and easy.

[0069] In other embodiments, the opening 130 may not be provided on the main frame 100. For example, the third connecting portion 440 and the fourth connecting portion 450 of the limiting bracket 400 may be located inside the mounting cavity 120, and the third connecting portion 440 and the fourth connecting portion 450 may be directly connected to the inner wall of the mounting cavity 120.

[0070] Optionally, such as Figure 1 As shown, the third connecting portion 440 may include a first protruding portion 441 and a first connecting plate 442. One end of the first protruding portion 441 can be connected to the limiting portion 410, and the other end of the first protruding portion 441 can pass through the opening 130 and connect to the first connecting plate 442. The first connecting plate 442 can be connected to the first side portion 140. The fourth connecting portion 450 may include a second protruding portion 451 and a second connecting plate 452. One end of the second protruding portion 451 can be connected to the limiting portion 410, and the other end of the second protruding portion 451 can pass through the opening 130 and connect to the second connecting plate 452. The second connecting plate 452 can be connected to the second side portion 150. This configuration facilitates the connection between the limiting bracket 400 and the main frame 100.

[0071] Alternatively, the height of the limiting part 410 can be adjusted so that the limiting part 410 can adapt to gaps of different sizes.

[0072] In some embodiments, both the first protruding portion 441 and the second protruding portion 451 can be telescopic structures. The height of the limiting portion 410 can be adjusted by extending and retracting the first protruding portion 441 and the second protruding portion 451. For example, both the first protruding portion 441 and the second protruding portion 451 can include a first connecting plate and a second connecting plate. The first connecting plate of the first protruding portion 441 can be connected to the first side portion 140, and the first connecting plate of the second protruding portion 451 can be connected to the limiting portion 410, and are respectively slidably connected to the corresponding first connecting portion. Through the relative sliding of the first connecting portion and the second connecting portion in the height direction, both the first protruding portion 441 and the second protruding portion 451 can form telescopic structures. To keep the first connecting plate and the second connecting plate in the desired position, the first connecting plate and the second connecting plate can be connected by fixing pins to prevent relative sliding, thereby keeping the limiting portion 410 at the desired height.

[0073] It should be noted that the height direction 'b' here can be the height direction of the vehicle body, that is, the vertical direction mentioned above.

[0074] In one alternative embodiment, such as Figure 3 As shown, in the direction from the first side 140 to the second side 150, the width of the opening 130 can be greater than or equal to the width of the limiting part 410, and the limiting part 410 can be inserted into the gap through the opening 130. In this embodiment, since the width of the opening 130 is greater than or equal to the width of the limiting part 410, when assembling the limiting bracket 400 and the main frame 100, the limiting part 410 can be inserted into the gap through the opening 130. This arrangement makes the assembly method simple and convenient, and easy for operators to operate.

[0075] In another alternative embodiment, the width of the limiting portion 410 may be greater than the width of the opening 130 in the direction from the first side 140 to the second side 150. This arrangement allows the limiting portion 410 to be vertically positioned and engaged with the main frame 100, preventing the limiting portion 410 from dislodging from the opening 130 and thus improving the stability of the limiting portion 410. In this embodiment, when assembling the limiting bracket 400, the limiting portion 410 can be embedded into the gap along the direction from the powertrain to the elastomer 200.

[0076] In optional embodiments, such as Figure 1 and Figure 3As shown, the third connecting part 440 can be connected to the first side part 140 via the first fixing member 600, and the fourth connecting part 450 can be connected to the second side part 150 via the second fixing member 700. This arrangement can improve the connection strength between the third connecting part 440 and the first side part 140, as well as the connection strength between the fourth connecting part 450 and the second side part 150. For example, the first fixing member 600 can be a fourth connecting bolt, and the third connecting part 440 can be connected to the first side part 140 via the fourth connecting bolt. Specifically, the third connecting part 440 can be provided with a first fixing hole, and the first side part 140 can be provided with a first threaded hole. The fourth connecting bolt can pass through the first fixing hole and be threaded into the first threaded hole. Furthermore, the diameter of the head of the fourth connecting bolt can be larger than the diameter of the first fixing hole, or a first washer can be provided between the head of the third connecting part 440 and the head of the fourth connecting bolt. The second fastener 700 can be a fifth connecting bolt. The fourth connecting part 450 can be connected to the second side part 150 through the fifth connecting bolt. Specifically, the fourth connecting part 450 can be provided with a second fixing hole, and the second side part 150 can be provided with a second threaded hole. The fifth connecting bolt can pass through the second fixing hole and be threaded into the second threaded hole. Furthermore, the diameter of the head of the fifth connecting bolt can be larger than the diameter of the second fixing hole. Alternatively, a second washer can be provided between the fourth connecting part 450 and the head of the fifth connecting bolt.

[0077] In other embodiments, the third connecting portion 440 and the first side portion 140 may not be connected by the first fastener 600, and the fourth connecting portion 450 and the second side portion 150 may not be connected by the second fastener 700. For example, the third connecting portion 440 and the first side portion 140 may be bonded, overlapped, snapped, or riveted, and the fourth connecting portion 450 and the second side portion 150 may be bonded, overlapped, snapped, or riveted.

[0078] Optionally, at least one of the first fastener 600 and the second fastener 700 can be used to secure cables connected to the powertrain. This configuration effectively improves the functionality of the suspension system and eliminates the need for additional fasteners for securing cables, thus reducing the number of fasteners, simplifying the vehicle's structure, and reducing its weight.

[0079] In other embodiments, both the first fixing member 600 and the second fixing member 700 may not be used to fix cables connected to the powertrain. For example, the vehicle may include a fixing structure that can be connected to the main frame 100 of the suspension device, or the fixing structure can be connected to the vehicle body and can be connected to cables to secure the cables to the suspension device or the vehicle body.

[0080] In some embodiments, cables connected to the powertrain can perform functions such as signal transmission and power supply, ensuring proper coordination between powertrain components and with other vehicle systems. Cables connected to the powertrain may include sensor cables, actuator cables, communication cables, and power cables.

[0081] In optional embodiments, such as Figures 1-4 As shown, the suspension device may further include a support arm 500, through which the elastomer 200 can be connected to the powertrain. Specifically, the middle portion of the support arm 500 can be connected to the elastomer 200, and the support arm 500 may be provided with at least two fourth connection holes 510, each fourth connection hole 510 being distributed along the length direction of the support arm 500. The fourth connection holes 510 can be used to connect to the powertrain, which improves the connection stability between the support arm 500 and the powertrain. For example, each fourth connection hole 510 can be connected to the powertrain via a sixth connecting bolt.

[0082] In optional embodiments of this application, such as Figure 1 and Figure 2 As shown, the suspension device may further include a hydraulic damping structure 300, which can be connected to the elastomer 200. Specifically, the hydraulic damping structure 300 can be located below the elastomer 200, and the hydraulic damping structure 300 and the elastomer 200 can be vulcanized into an integral structure. During assembly, the hydraulic damping structure 300 and the elastomer 200 can be assembled together into the mounting cavity 120. During vehicle operation, when uneven road surfaces cause vibrations, the hydraulic damping structure 300 can effectively attenuate the vibration amplitude and intensity, reducing or preventing vibration transmission to the powertrain and vehicle body, thereby reducing powertrain vibration and vehicle body vibration, and thus improving driving and riding comfort. In this embodiment, the elastomer 200 can be made of rubber.

[0083] Optionally, in the vertical direction, the hydraulic damping structure 300 can be limited and engaged with the main frame 100 to prevent the hydraulic damping structure 300 from moving in the vertical direction. Furthermore, in the first direction a, the hydraulic damping structure 300 is limited and engaged with the main frame 100 to prevent the hydraulic damping structure 300 from moving relative to the main frame 100 in the first direction a. Here, the first direction a is perpendicular to both the vertical direction and the direction from the elastic body 200 to the powertrain.

[0084] In an optional embodiment, the limiting bracket 400 can be made of sheet metal. Since sheet metal has good ductility and strength, it can improve the strength of the limiting bracket 400 so that the limiting bracket 400 can adapt to large impact conditions.

[0085] Optionally, the main frame 100 can be made of sheet metal or aluminum, and the support arm 500 can be made of aluminum.

[0086] In the embodiments of this application, when assembling the suspension device, the main frame 100 equipped with the elastomer 200 can be connected to the vehicle body first, and then the elastomer 200 can be connected to the powertrain via the support arm 500. The powertrain's own weight is used to compress the elastomer 200. This arrangement allows the powertrain's own weight to compress the elastomer 200, resulting in a simple process, high reliability, and eliminating the need for specialized equipment to compress the elastomer 200 during the suspension device's production process, thus reducing manufacturing costs and improving production efficiency. Finally, the limiting bracket 400 is installed onto the main frame 100, so that the limiting part 410 is embedded in the vertical gap between the elastomer 200 and the main frame 100.

[0087] Based on the suspension device provided in the embodiments of this application, the embodiments of this application also provide a vehicle, which may include a body, a powertrain and the suspension device described in any of the above embodiments. The powertrain may be connected to the elastomer 200 of the suspension device, and the main frame 100 of the suspension device may be connected to the body.

[0088] The beneficial effects achieved by the vehicle provided in this application embodiment are consistent with the beneficial effects achieved by the suspension device provided in this application embodiment, and will not be repeated here.
