Description

Technical Field

[0001] The utility model relates to the technical field of vehicle suspension, and in particular to a suspension assembly. The utility model also relates to a vehicle equipped with the suspension assembly. Background Art

[0002] Currently, in the development of automobiles, engine layouts vary widely. With the advancement of automotive technology, certain typical layouts for powertrain components, such as engines and transmissions, have gradually emerged. For example, a longitudinal layout places the engine longitudinally at the front of the vehicle, with the engine crankshaft aligned with the direction of travel. This layout is common in some rear-wheel drive or four-wheel drive vehicles, facilitating ideal front-to-rear axle weight distribution and improving vehicle handling.

[0003] Because the crankshaft of a longitudinally mounted engine rotates in the same direction as the vehicle's travel, its vibration transmission path differs from that of a transversely mounted engine. Therefore, the torsional vibration of a longitudinally mounted engine may have a more direct impact on the vehicle's ride smoothness. To accommodate the characteristics of a longitudinally mounted powertrain, a longitudinal suspension system is often employed to effectively isolate the engine's low-frequency vibrations and prevent noticeable body shake.

[0004] However, the existing longitudinal suspension structures mostly use bolts for limiting the position. After being subjected to alternating loads for a long time, the bolts are prone to fatigue cracks, which may cause the suspension system to lose effective limiting and cause serious damage. In addition, the assembly process of this limiting structure is relatively complicated and has many parts, which is not conducive to simplifying the production process and reducing production costs. Utility Model Content

[0005] In view of this, the present invention aims to provide a suspension assembly to simplify the production process and reduce production costs.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0007] A suspension assembly includes an upper connecting plate, a lower connecting plate, a rubber main spring, and a first rubber limiter; an accommodating space is provided between the upper connecting plate and the lower connecting plate, and the upper connecting plate and the lower connecting plate are connected by the rubber main spring;

[0008] The first rubber limiting portion is provided on one of the upper connecting plate and the lower connecting plate, and is a plurality of the first rubber limiting portions located within the accommodating space. A gap is provided between the first rubber limiting portion and the other of the upper connecting plate and the lower connecting plate, and the first rubber limiting portion can abut against the other of the upper connecting plate and the lower connecting plate to limit the relative position of the upper connecting plate and the lower connecting plate.

[0009] Furthermore, the first rubber limiting portion is provided on the upper connecting plate; the two rubber main springs are symmetrically arranged in the accommodating space, and the first rubber limiting portion is located between the two rubber main springs; there are two first rubber limiting portions, and the connection direction of the two first rubber limiting portions intersects with the connection direction of the two rubber main springs.

[0010] Furthermore, the upper connecting plate includes an upper connecting plate body and a limiting portion mounting portion provided on the upper connecting plate body; the limiting portion mounting portion has a limiting portion located in the accommodating space, and at least the limiting portion is provided with the first rubber limiting portion.

[0011] Furthermore, the limiting portion mounting portion includes a first plate body connected to the upper connecting plate body, and a second plate body connected to the first plate body; the first plate body extends from the upper connecting plate body to the lower connecting plate, and the second plate body extends from the first plate body into the accommodating space; the first rubber limiting portion is arranged on the side of the second plate body facing the lower connecting plate.

[0012] Furthermore, the first plate body and the second plate body are formed by bending parts of the upper connecting plate in sequence.

[0013] Furthermore, the lower connecting plate includes a lower connecting plate body and a third plate body provided on the lower connecting plate body; the third plate body extends from the lower connecting plate body to the upper connecting plate, and a second rubber limiting portion is provided between the third plate body and the first plate body.

[0014] Furthermore, a fourth plate body connected to the third plate body is provided on the lower connecting plate; the fourth plate body extends from the third plate body to above the upper connecting plate body, and a third rubber limiting portion is provided between the fourth plate body and the upper connecting plate body.

[0015] Furthermore, the first rubber limiting portion, the second rubber limiting portion and the third rubber limiting portion are integrally formed; and / or the third plate body and the fourth plate body are formed by sequentially bending parts of the lower connecting plate.

[0016] Furthermore, the upper connecting plate is provided with an installation avoidance portion, and during the assembly process of the upper connecting plate and the lower connecting plate, the installation avoidance portion is used to avoid the third plate body and the fourth plate body.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] In the suspension assembly described in the present invention, an accommodation space is formed between the upper connecting plate and the lower connecting plate, and the first rubber limiter is provided on one of the upper connecting plate and the lower connecting plate. The first rubber limiter is located inside the accommodation space and has a certain gap with the other connecting plate. The existence of this gap allows the first rubber limiter to have a certain movable space when the suspension assembly is subjected to an external force and causes the upper connecting plate and the lower connecting plate to have a tendency to move relative to each other. The first rubber limiter will come into contact with and abut against the connecting plate on which the first rubber limiter is not installed. This abutment can effectively limit the relative position change between the upper connecting plate and the lower connecting plate, thereby ensuring the stability and reliability of the suspension assembly.

[0019] The suspension assembly can effectively absorb and limit external vibrations through the limiting action of the rubber main spring and the first rubber limiting part, thereby ensuring the stability and other performance of the entire system. The suspension assembly can eliminate existing bolts and reduce the number of parts. The first rubber limiting part can be bonded or vulcanized on the upper connecting plate or the lower connecting plate, which can simplify the production process and help reduce production costs. Setting a plurality of first rubber limiting parts can help improve the stability and reliability of the limitation.

[0020] Secondly, the first rubber stopper is located between the two main rubber springs. This layout helps ensure that when the vehicle sways from side to side or is subjected to lateral forces, the first rubber stopper can evenly absorb and distribute these forces, thereby maintaining the stability and balance of the suspension assembly. The presence of two first rubber stoppers, with the line connecting the two first rubber stoppers intersecting the line connecting the two main rubber springs, evenly absorbs and distributes external forces acting on the suspension assembly from different directions. This design further enhances the stability and impact resistance of the suspension assembly.

[0021] When the suspension assembly is in use on a vehicle, the two first rubber stoppers work together to more effectively absorb and disperse these forces, protecting the suspension assembly and connected components from damage. The specific location, layout, and number of the first rubber stoppers on the upper connecting plate ensure the suspension assembly's performance under various operating conditions, providing reliable support and shock absorption for the vehicle.

[0022] Furthermore, the upper connecting plate primarily consists of an upper connecting plate body and a stopper mounting portion. The upper connecting plate body is the primary structural component of the connecting plate and serves to connect to the powertrain. The stopper mounting portion is specifically designed to mount the first rubber stopper, ensuring accurate and stable installation of the first rubber stopper on the stopper mounting portion. At least a portion of the stopper mounting portion is located within the accommodation space. When subjected to external forces, the first rubber stopper can fully utilize the space within the accommodation space to absorb energy, thereby enhancing the shock absorption effect of the suspension assembly.

[0023] The first plate body is a transition part connecting the upper connecting plate body and the second plate body. It is intended to ensure that the second plate body can be stably installed on the upper connecting plate and provide a reliable installation base for the first rubber limit part. The second plate body is parallel to the upper connecting plate, which is conducive to providing a larger installation area for the first rubber limit part, so as to ensure the limiting and shock-absorbing functions.

[0024] In addition, the first plate body and the second plate body are formed by bending parts of the upper connecting plate in sequence, and the entire limit portion mounting portion and the upper connecting plate form an integral structure, which can reduce additional connecting parts and assembly steps. The structure formed by bending usually has higher strength and rigidity than the structure connected by welding or bolts. At the same time, the use of sheet metal forming technology can also reduce material waste and processing time, thereby reducing manufacturing costs. Compared with the relatively complex welding or bolt connection, this one-piece bending sheet metal forming process is relatively simple and easy to automate.

[0025] The lower connecting plate is primarily composed of a lower connecting plate body and a third plate. The lower connecting plate body serves as the primary connection and structural support, connecting to the vehicle frame and securing and supporting the suspension assembly. The third plate is the lower connecting plate, which may be connected to the lower connecting plate body through integral molding, welding, bolting, riveting, or other fastening methods.

[0026] The second rubber stopper is positioned between the third plate and the first plate. When the suspension assembly is subjected to external forces in the vehicle's fore-aft direction, the second rubber stopper absorbs and disperses these forces, thereby improving the suspension assembly's position-limiting and shock-absorbing performance. The first and second rubber stoppers work together to maintain the stability and reliability of the suspension assembly in the fore-aft and up-and-down directions under various operating conditions, while also reducing vibration and noise transmitted to the vehicle body.

[0027] In addition, the fourth plate body provided can ensure that the third rubber limit part can be correctly installed and function, and at the same time can improve the stability and reliability of the connection between the upper connecting plate and the lower connecting plate. In the up and down directions of the entire vehicle, the fourth plate body can prevent the gap between the upper connecting plate and the lower connecting plate from being too large, which causes the rubber main spring to be excessively stretched. The third rubber limit part cooperates with the first rubber limit part and the second rubber limit part, which can not only provide limitation and shock absorption in the front and rear directions, but also play the same role in the up and down directions, which can better improve the overall performance of the suspension assembly and provide strong and reliable guarantees for the stable operation of the suspension assembly under various complex working conditions.

[0028] At the same time, the third and fourth plates are formed by sequentially bending portions of the lower connecting plate, forming an integral structure with the lower connecting plate, thereby reducing the need for additional connectors and assembly steps. Compared to relatively complex welding or bolted connections, the bent structure has greater strength and rigidity. The use of sheet metal forming processes also reduces material waste and processing time, thereby lowering manufacturing costs. This integrally bent sheet metal forming process is relatively simple and amenable to automated production. The provision of an installation avoidance portion prevents interference or collision between the upper and lower connecting plates during assembly, ensuring a smooth and efficient assembly process.

[0029] Another object of the present invention is to provide a vehicle, wherein the powertrain of the vehicle is mounted on the vehicle body via the suspension assembly as described above.

[0030] The vehicle of the present invention has the same beneficial effects as the above-mentioned suspension assembly, and will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Taking the vehicle in which the suspension assembly described in the present invention is located as an example, the directional words used in the embodiments, such as "up, down, left, right, front, and back", are based on the vehicle's position. Figure 1 The vehicle is defined based on the up-down direction (also known as the height direction, or the Z direction of the vehicle), the left-right direction (also known as the length direction, or the Y direction of the vehicle), and the front-back direction (also known as the width direction, or the X direction of the vehicle) in the shown state.

[0046] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0047] Example 1

[0048] This embodiment relates to a suspension assembly that can eliminate existing bolts, thereby reducing the number of parts, simplifying the production process, and helping to reduce production costs.

[0049] In terms of overall structure, combined Figures 1 to 4 As shown in FIG, the suspension assembly of this embodiment includes an upper connecting plate 1, a lower connecting plate 2, a rubber main spring 3, and a first rubber limiter 41. An accommodating space 5 is provided between the upper connecting plate 1 and the lower connecting plate 2, and the upper connecting plate 1 and the lower connecting plate 2 are connected by the rubber main spring 3.

[0050] At the same time, a first rubber limiting portion 41 is provided on one of the upper connecting plate 1 and the lower connecting plate 2, and is located in a plurality of positions within the accommodating space 5. A gap is provided between the first rubber limiting portion 41 and the other of the upper connecting plate 1 and the lower connecting plate 2, and the first rubber limiting portion 41 can abut against the other of the upper connecting plate 1 and the lower connecting plate 2 to limit the relative position of the upper connecting plate 1 and the lower connecting plate 2.

[0051] It can be understood that the suspension assembly described in the present invention forms an accommodating space 5 between the upper connecting plate 1 and the lower connecting plate 2, and the first rubber limiter 41 is provided on one of the upper connecting plate 1 and the lower connecting plate 2. It is located inside the accommodating space 5 and there is a certain gap between it and the other connecting plate. The existence of this gap allows the suspension assembly to have a certain amount of space for movement when the upper connecting plate 1 and the lower connecting plate 2 tend to move relative to each other due to external force. The first rubber limiter 41 will come into contact with and abut against the connecting plate on which the first rubber limiter 41 is not installed. This abutment can effectively limit the relative position change between the upper connecting plate 1 and the lower connecting plate 2, thereby ensuring the stability and reliability of the suspension assembly.

[0052] In addition, the suspension assembly can effectively absorb and limit external vibrations through the limiting effects of the rubber main spring 3 and the first rubber limiting portion 41, thereby ensuring the stability and other performance of the entire system. The suspension assembly can eliminate the existing bolts 22, thereby reducing the number of parts, simplifying the production process, and helping to reduce production costs. Setting the first rubber limiting portion 41 to multiple parts is beneficial to improving the stability and reliability of the limitation.

[0053] Here, in this embodiment, two rubber main springs 3 can be provided. The specific implementation can refer to existing technologies. For example, two rubber main springs 3 are symmetrically arranged within the accommodation space 5. When used on a vehicle, the two rubber main springs 3 are spaced apart along the left-right direction of the vehicle. Specifically, the two rubber main springs 3 are symmetrically arranged about the centerline of the suspension assembly along the left-right direction of the vehicle, and the rubber main springs 3 can be connected to the upper connecting plate 1 and the lower connecting plate 2 respectively through a vulcanization process. Furthermore, the first rubber stoppers 41 in this embodiment can be arranged along the spacing in the front-to-back direction of the vehicle, along the left-to-right direction of the vehicle, or in a random arrangement.

[0054] In specific structure, the upper connecting plate 1 and the lower connecting plate 2 in this embodiment can be arranged in a V-shaped structure according to the prior art. Furthermore, the upper connecting plate 1 has connecting holes 14 formed on its two inclined plates, through which the upper connecting plate 1 can be fixedly connected to the powertrain (i.e., the transmission or electric drive). The lower connecting plate 2 has bolts 22 fixedly connected to its horizontal plate, thereby allowing the lower connecting plate 2 to be fixedly connected to the vehicle frame.

[0055] Based on the above overall introduction, in this embodiment, as a preferred implementation form, refer to Figure 1 and Figure 2 As shown in FIG, a first rubber stopper 41 is provided on the upper connecting plate 1 and is located between the two rubber main springs 3. In a preferred embodiment, there are two first rubber stoppers 41, and the connecting line of the two first rubber stoppers 41 intersects the connecting line of the two rubber main springs 3.

[0056] When the suspension assembly is used on a vehicle, the first rubber limiter 41 is located in the middle of the accommodating space 5 along the left-right direction of the vehicle, and there are two first rubber limiters 41 spaced apart in the front-to-back direction of the vehicle. The angle between the connecting direction of the two first rubber limiters 41 and the connecting direction of the two rubber main springs 3 is preferably 90°. It should be understood that the angle between the connecting direction of the two first rubber limiters 41 and the connecting direction of the two rubber main springs 3 can be other angles besides 90°, such as 70°, 80°, etc.

[0057] Here, the first rubber stopper 41 is located in the middle of the accommodating space 5 in the left-right direction of the vehicle. This layout helps ensure that when the vehicle sways left and right or is subjected to lateral forces, the first rubber stopper 41 can evenly absorb and disperse these forces, thereby maintaining the stability and balance of the suspension assembly.

[0058] Furthermore, two first rubber stoppers 41 are spaced apart in the vehicle's fore-aft direction. This design further enhances the suspension assembly's fore-aft stability and impact resistance. When the vehicle rockes or is subjected to fore-aft forces, the two first rubber stoppers 41 work together to more effectively absorb and disperse these forces, protecting the suspension assembly and its connected components from damage. The specific location, layout, and number of first rubber stoppers 41 on the upper connecting plate 1 ensure the suspension assembly's performance under various operating conditions, providing reliable support and shock absorption.

[0059] Specifically, in this embodiment, as a preferred implementation form, Figure 1 and Figure 3 As shown in , the upper connecting plate 1 includes an upper connecting plate body 11 and a limiting portion mounting portion 12 provided on the upper connecting plate body 11 .

[0060] It can be understood that the upper connecting plate 1 is mainly composed of an upper connecting plate body 11 and a limit portion mounting portion 12. The upper connecting plate body 11 is the main structural part of the connecting plate, which is used to connect to the powertrain. The limit portion mounting portion 12 is specially designed to install the first rubber limit portion 41, which can ensure that the first rubber limit portion 41 can be accurately and stably installed on the limit portion mounting portion 12.

[0061] Furthermore, the stopper mounting portion 12 includes a stopper portion located within the accommodating space 5, and a first rubber stopper 41 is provided on at least this stopper portion. Here, since at least a portion of the stopper mounting portion 12 is located within the accommodating space 5, when subjected to external forces, the first rubber stopper 41 can fully utilize the space within the accommodating space 5 to absorb energy, thereby enhancing the shock absorption effect of the suspension assembly.

[0062] Furthermore, in this embodiment, as a preferred implementation form, Figure 3 As shown in , the position-limiting portion mounting portion 12 includes a first plate 121 connected to the upper connecting plate body 11, and a second plate 122 connected to the first plate 121. Specifically, the first plate 121 extends from the upper connecting plate body 11 to the lower connecting plate 2, and the second plate 122 extends from the first plate 121 into the accommodating space 5.

[0063] Here, the first plate body 121 is a transition portion connecting the upper connecting plate body 11 and the second plate body 122 , which is intended to ensure that the second plate body 122 can be stably installed on the upper connecting plate 1 and provide a reliable installation foundation for the first rubber limiter 41 .

[0064] At the same time, the second plate 122 is parallel to the upper connecting plate 1, and the first rubber stopper 41 is provided on the side of the second plate 122 facing the lower connecting plate 2. This arrangement has the advantage of providing a larger installation area for the first rubber stopper 41, thereby ensuring the limiting and shock-absorbing functions.

[0065] Moreover, as a preferred embodiment, Figure 3 As shown in FIG, the first plate 121 and the second plate 122 of this embodiment are formed by sequentially bending portions of the upper connecting plate 1. This arrangement allows the entire stopper mounting portion 12 and the upper connecting plate 1 to form an integral structure, reducing the number of additional connectors and assembly steps. The bent structure generally has higher strength and rigidity than structures connected by welding or bolts 22.

[0066] At the same time, the use of sheet metal forming technology can also reduce material waste and processing time, thereby reducing manufacturing costs. Compared with the relatively complex welding or bolt 22 connection, this one-piece bending sheet metal forming process is relatively simple and easy to automate.

[0067] In addition, in this embodiment, as a preferred implementation form, Figure 2 and Figure 4 As shown in , the lower connecting plate 2 includes a lower connecting plate body 21 and a third plate body 211 provided on the lower connecting plate body 21 .

[0068] It is understood that the lower connecting plate 2 is primarily composed of the lower connecting plate body 21 and the third plate body 211. The lower connecting plate body 21 serves as the primary connection and structural support component, connecting to the vehicle frame and securing and supporting the suspension assembly. Furthermore, the third plate body 211 may be connected to the lower connecting plate body 21 by welding, bolting, riveting, or other fastening methods.

[0069] Specifically, the third plate body 211 extends from the lower connecting plate body 21 to the upper connecting plate 1 , and a second rubber limiting portion 42 is disposed between the third plate body 211 and the first plate body 121 .

[0070] Here, the second rubber stopper 42 is positioned between the third plate 211 and the first plate 121. When the suspension assembly is subjected to external forces in the vehicle's fore-aft direction, the second rubber stopper 42 absorbs and disperses these forces, thereby improving the suspension assembly's position-limiting and shock-absorbing performance. The first and second rubber stoppers 41, 42 work together to maintain the stability and reliability of the suspension assembly in the fore-aft and up-and-down directions under various operating conditions, while also reducing vibration and noise transmitted to the vehicle body.

[0071] In addition, as a preferred embodiment, still refer to Figure 2 and Figure 4 As shown in , the lower connecting plate 2 of this embodiment is provided with a fourth plate 212 connected to the third plate 211. The fourth plate 212 extends from the third plate 211 to above the upper connecting plate body 11. More specifically, the fourth plate 212 is parallel to the upper connecting plate body 11, and a third rubber stopper 43 is provided between the fourth plate 212 and the upper connecting plate body 11.

[0072] At this time, as set above, by setting the fourth plate body 212, it can be ensured that the third rubber limit part 43 can be correctly installed and function, and at the same time the stability and reliability of the connection between the upper connecting plate 1 and the lower connecting plate 2 can be improved. In the up and down directions of the entire vehicle, the fourth plate body 212 can prevent the gap between the upper connecting plate 1 and the lower connecting plate 2 from being too large, which causes the rubber main spring 3 to be over-stretched.

[0073] At the same time, the third rubber limit portion 43 cooperates with the first rubber limit portion 41 and the second rubber limit portion 42 to not only provide limitation and shock absorption in the front-to-back direction, but also play the same role in the up-down direction, which can effectively improve the overall performance of the suspension assembly and provide a strong and reliable guarantee for the stable operation of the suspension assembly under various complex working conditions.

[0074] Furthermore, considering the need for process simplification, in this embodiment, as a preferred implementation, the first rubber stopper 41, the second rubber stopper 42, and the third rubber stopper 43 are integrally formed. This configuration reduces the traditional steps of separate molding followed by gluing, significantly improving production efficiency and overall product performance.

[0075] It should be noted that the primary material used to make the rubber main spring 3, first rubber stopper 41, second rubber stopper 42, and third rubber stopper 43 in this embodiment is over 70% rubber, resulting in excellent high-frequency vibration isolation for the suspension assembly. Furthermore, the primary material used to make the upper and lower connecting plates 1 and 2 in this embodiment is over 80% iron.

[0076] At the same time, the third plate 211 and the fourth plate 212 are formed by sequentially bending portions of the lower connecting plate 2. This allows them to form an integral structure with the lower connecting plate 2, thereby reducing the number of additional connectors and assembly steps. Compared to relatively complex welding or bolt connections, the bent structure has greater strength and rigidity. The use of sheet metal forming processes also reduces material waste and processing time, thereby lowering manufacturing costs. This integrally bent sheet metal forming process is relatively simple and easily automated.

[0077] In addition, in this embodiment, as a preferred implementation form, Figure 3 As shown in , the upper connecting plate 1 is provided with an installation avoidance portion 13 . During the assembly process of the upper connecting plate 1 and the lower connecting plate 2 , the installation avoidance portion 13 is used to avoid the third plate body 211 and the fourth plate body 212 .

[0078] Here, by providing the installation avoidance portion 13, interference or collision between the upper connecting plate 1 and the lower connecting plate 2 can be avoided during assembly, thereby ensuring a smooth and efficient assembly process. In the specific structure, the installation avoidance portion 13 is a avoidance groove provided on the upper connecting plate body 11, which is recessed toward the middle of the upper connecting plate body 11 along the front-to-back direction of the entire vehicle.

[0079] Finally, it should be noted that the above embodiment uses the example of a first rubber stopper 41 being provided on the upper connecting plate 1, with a gap provided between the first rubber stopper 41 and the lower connecting plate 2. Alternatively, the first rubber stopper 41 may be provided on the lower connecting plate 2, in which case a gap is provided between the first rubber stopper 41 and the upper connecting plate 1.

[0080] Alternatively, first rubber stoppers 41 may be provided on both the upper connecting plate 1 and the lower connecting plate 2. The number of first rubber stoppers 41 on each of the upper connecting plate 1 and the lower connecting plate 2 may be adjusted according to actual needs, for example, one or three. In this case, a gap may be provided between the first rubber stoppers 41 on the upper connecting plate 1 and the first rubber stoppers 41 on the lower connecting plate 2, or between the first rubber stoppers 41 on the upper connecting plate 1 and the lower connecting plate 2, or between the first rubber stoppers 41 on the lower connecting plate 2 and the upper connecting plate 1. All of these are feasible.

[0081] It should be understood that the above embodiment is based on the example of two first rubber stoppers 41 within the accommodation space 5. In other embodiments, the number of first rubber stoppers 41 is also feasible, such as one, three, etc. In a preferred embodiment, multiple first rubber stoppers 41 are evenly distributed within the accommodation space 5, which is conducive to effectively limiting the relative movement of the upper connecting plate 1 and the lower connecting plate 2. The specific arrangement of the first rubber stoppers 41 is not specifically limited here. During assembly of the suspension assembly of this embodiment, the first rubber stoppers 41, the second rubber stoppers 42, and the third rubber stoppers 43 are vulcanized onto the upper connecting plate 1. The upper connecting plate 1 and the lower connecting plate 2 are then placed in a mold. The rubber main spring 3 is formed by the vulcanization process to connect the upper connecting plate 1 and the lower connecting plate 2 together, thereby eliminating existing bolts, reducing the number of parts, and simplifying the production process and reducing production costs. Finally, the lower connecting plate 2 is fixedly connected to the vehicle frame, and the vehicle powertrain is connected to the upper connecting plate 1.

[0082] Example 2

[0083] This embodiment relates to a vehicle, the powertrain of which is mounted on the vehicle body via the suspension assembly of the first embodiment.

[0084] The vehicle of this embodiment adopts the suspension assembly of Example 1, which can reduce the number of parts, simplify the production process, and help reduce production costs. In addition, the limiting dimensions of the suspension assembly along the front and rear directions of the vehicle and the limiting dimensions along the left and right directions of the vehicle are both large, which can increase the limiting area, making the suspension assembly have excellent durability performance, and its application in vehicles is beneficial to improving the comfort of the vehicle.

[0085] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
