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, when a car is in motion, the engine generates a certain amount of vibration. This vibration can be transmitted to the subframe, causing discomfort to passengers. To reduce subframe vibration, a mount is often inserted between the engine and the subframe, connecting both. This mount reduces the vibration transmitted from the engine to the subframe, thereby ensuring a comfortable passenger experience.

[0003] Matching suspensions with different performance characteristics to different vehicle models can balance the dual requirements of suspension production costs and vehicle comfort. Suspension performance primarily depends on the hardness and stiffness of the rubber between the inner core and the sleeve. Existing suspensions typically consist of an inner core and a sleeve with rubber between them. Due to structural limitations, these suspensions lack flexibility and versatility when applied to different vehicle models, failing to balance production costs and vehicle comfort requirements.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A suspension assembly includes multiple sub-suspensions, and the multiple sub-suspensions can be connected in sequence along the axial direction of the suspension assembly; a stop structure is provided between the inner cores of any adjacent sub-suspensions, and the stop structure is used to prevent the adjacent sub-suspensions from rotating around the axial direction of the suspension assembly.

[0007] Furthermore, the plurality of sub-suspensions include a first sub-suspension and a second sub-suspension, and the first sub-suspension and the second sub-suspension are alternately arranged in sequence along the axial direction of the suspension assembly; the inner core of the first sub-suspension is a first inner core, and a first sleeve is provided on the outer surface of the first inner core, and a first main spring rubber is connected between the first and second sub-suspensions;

[0008] The inner core of the second sub-suspension is a second inner core, and a second sleeve is provided on the outer cover of the second inner core. A limiting rubber is provided on one of the second inner core and the second sleeve, and the limiting rubber can abut against the other of the second inner core and the second sleeve, thereby limiting the relative position of the second inner core and the second sleeve in the radial direction of the suspension component.

[0009] Furthermore, there are a plurality of first main spring rubbers, and the plurality of first main spring rubbers are arranged at intervals around the circumference of the first inner core.

[0010] Furthermore, the second inner core includes a second inner core body and a limiting rubber mounting portion provided on the second inner core body, the limiting rubber mounting portion protrudes in a radial direction away from the second inner core body along the suspension component, and the limiting rubber is provided on the limiting rubber mounting portion.

[0011] Furthermore, there are a plurality of the limiting rubber mounting parts, which are arranged at intervals in the circumferential direction around the second inner core body, and each of the limiting rubber mounting parts is provided with the limiting rubber.

[0012] Furthermore, along the axial direction of the suspension assembly, each of the first main spring rubbers has a protruding portion protruding toward the adjacent second sub-suspension relative to the first inner core;

[0013] The limiting rubber mounting portion and the limiting rubber both extend along the axial direction of the suspension assembly, and both ends of the limiting rubber mounting portion and the limiting rubber abut against the protruding portions at both ends respectively.

[0014] Furthermore, the second sleeve is integrated with any adjacent first sleeve into an integral structure; or,

[0015] There are two second sleeves in the second sub-suspension, the two second sleeves are axially connected to the components of the suspension, and the two second sleeves are respectively integrated with adjacent first sleeves to form an integral structure.

[0016] Furthermore, the anti-rotation structure includes an anti-rotation protrusion provided on one of the two adjacent inner cores, and an anti-rotation groove provided on the other of the two adjacent inner cores, and the anti-rotation protrusion is embedded in the anti-rotation groove.

[0017] Furthermore, there are multiple anti-rotation structures, and the multiple anti-rotation structures are distributed at intervals around the circumference of the inner core.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] The suspension assembly of the present invention facilitates adjustment of the number of sub-suspensions during use, making assembly and disassembly very convenient. The length or structure of each sub-suspension can be adjusted according to actual needs. Each sub-suspension can also be matched with rubber of different hardness and stiffness. Different sub-suspensions can be combined to form suspension assemblies with different performances, thereby improving the flexibility and versatility of the suspension assembly. The provision of a rotation-stop structure effectively prevents adjacent sub-suspensions from rotating about the assembly axis, thereby ensuring the stability and reliability of the entire suspension assembly. When used on different vehicle models, different sub-suspensions can be combined to balance the cost of the suspension assembly with the comfort of the vehicle's ride.

[0020] Secondly, the rubber of each sub-suspension can be made of rubber with different stiffness, which makes the suspension component have a wide range of applications, a reliable structure, and excellent vibration reduction performance. The first inner core serves as the core component of the first sub-suspension and plays a supporting and connecting role. The first sleeve is arranged on the outside of the first inner core and is connected to the first inner core through the first main spring rubber. The first main spring rubber plays the role of elastic support and vibration reduction, which helps to absorb and disperse vibration energy and improve the vibration isolation performance of the suspension component.

[0021] The second inner core, the core component of the second sub-suspension, also provides support and connection. A stopper rubber, located on one of the second inner core and the second sleeve, abuts against the other, limiting the relative position of the second inner core and the second sleeve in the radial direction of the suspension assembly, thereby enhancing the stability of the suspension assembly. The first and second sub-suspensions are arranged alternately along the axial direction of the suspension assembly. This arrangement ensures excellent stability and load-bearing capacity in both the axial and radial directions.

[0022] Furthermore, the circumferential spacing of the first main spring rubber around the first inner core helps to more evenly absorb and disperse vibration energy from all directions. The synergistic effect of the first and second sub-suspensions makes the suspension assembly more stable and reliable in complex vibration environments, providing a strong guarantee for the excellent performance of the suspension assembly. The second inner core body is used to provide the necessary support and connection functions. The provided limit rubber mounting portion allows the limit rubber to be securely installed on the second inner core and can provide effective limiting in the radial direction of the suspension assembly, thereby ensuring that the suspension assembly can remain stable under vibration or impact conditions.

[0023] Furthermore, the positioning rubber mounting portions on the second inner core are arranged at intervals around the circumference of the second inner core body, helping to more evenly distribute the positioning force provided by the positioning rubber, ensuring stable support and positioning of the second inner core in multiple directions, thereby improving the overall stability and load-bearing capacity of the suspension assembly. Along the axial direction of the suspension assembly, each first main spring rubber has a protruding portion that projects from the first inner core toward the adjacent second sub-suspension. The presence of this protruding portion helps increase the contact area between the rubber of the first and second sub-suspensions, thereby improving the connection stability and load-bearing capacity between them, and also provides the suspension assembly with excellent vibration damping performance in its own axial direction.

[0024] The second sleeve is integrated into an integral structure with any adjacent first sleeve, and the two second sleeves are connected in the axial direction of the suspension assembly and are respectively integrated into an integral structure with the adjacent first sleeves, which helps to improve the rigidity and stability of the suspension assembly and can reduce the connection points between adjacent sub-suspensions, thereby reducing the potential risk of loosening. This structure helps to improve the load-bearing capacity of the suspension assembly, enabling it to cope with more complex vibration and impact environments.

[0025] The anti-rotation structure, comprising anti-rotation protrusions and anti-rotation grooves, effectively prevents relative rotation between the inner cores, improving the stability and reliability of the suspension assembly. Furthermore, the anti-rotation structure offers advantages such as low cost, simple manufacturing, and strong adaptability. Multiple anti-rotation structures are spaced circumferentially around the inner cores, helping to more evenly distribute the anti-rotation force they provide. This ensures that the inner cores are stably supported and restrained in multiple directions, reliably preventing relative rotation between adjacent inner cores. This design also helps to improve the overall stability and load-bearing capacity of the suspension assembly.

[0026] In addition, another object of the present invention is to provide a vehicle, in which the suspension assembly as described above is provided.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0045] Example 1

[0046] This embodiment relates to a suspension assembly that can meet the requirements of different stiffnesses of the limit rubber and the main spring rubber, thereby facilitating improvement of the flexibility and versatility of the suspension assembly.

[0047] In terms of overall structure, combined Figures 1 to 7 As shown in , the suspension assembly of this embodiment includes a plurality of sub-suspensions 1, which can be sequentially connected along the axial direction of the suspension assembly. Each sub-suspension 1 includes an inner core, and a rotation-stopping structure 3 is provided between the inner cores of any adjacent sub-suspensions 1. The rotation-stopping structure 3 is used to prevent adjacent sub-suspensions 1 from rotating about the axial direction of the suspension assembly.

[0048] At this time, as set above, the suspension assembly of the utility model is convenient for adjusting the number of sub-suspensions 1 when used, and is very convenient for assembly and disassembly. The length or structure of each sub-suspension 1 can be adjusted according to actual needs, which is beneficial to improving the flexibility and versatility of the suspension assembly. The anti-rotation structure 3 is set to effectively prevent the adjacent sub-suspensions 1 from rotating around the axial direction of the assembly, thereby ensuring the stability and reliability of the entire suspension assembly.

[0049] It should be noted that the structural design of the above-mentioned suspension assembly is suitable for cylindrical suspension, and in specific implementation, multiple sub-suspensions 1 are connected by connecting parts such as bolts passing through the inner core. When the suspension assembly is subjected to external force, each sub-suspension 1 will jointly bear the load and maintain overall stability through bolts.

[0050] Based on the above overall introduction, in this embodiment, as a preferred implementation form, as Figure 2 and Figure 3 As shown in FIG, the plurality of sub-suspensions 1 include a first sub-suspension 11 and a second sub-suspension 12, and the first sub-suspension 11 and the second sub-suspension 12 are alternately arranged in sequence along the axial direction of the suspension assembly.

[0051] With this arrangement, the rubber components of each sub-mount 1 can be made of rubber with different stiffnesses, making the suspension assembly widely applicable, structurally reliable, and offering excellent vibration damping performance. Furthermore, the first sub-mounts 11 and second sub-mounts 12 are alternately arranged along the axial direction of the suspension assembly, providing the suspension assembly with excellent stability and load-bearing capacity in both the axial and radial directions. Specifically, in this embodiment, two first sub-mounts 11 and one second sub-mount 12 are provided.

[0052] Furthermore, the inner core of the first sub-suspension 11 is the first inner core 21, which is surrounded by a first sleeve 111, with a first main spring rubber 112 connected between the first inner core 21 and the first inner core 21. Here, the first inner core 21 serves as the core component of the first sub-suspension 11, providing support and connection. The first sleeve 111 is sleeved outside the first inner core 21 and connected to the first inner core 21 via the first main spring rubber 112. The first main spring rubber 112 provides elastic support and vibration damping, helping to absorb and disperse vibration energy and improve the vibration isolation performance of the suspension assembly.

[0053] At the same time, the inner core of the second sub-suspension 12 is the second inner core 22, and the second inner core 22 is provided with a second sleeve 121. A limiting rubber 2221 is provided on one of the second inner core 22 and the second sleeve 121. The limiting rubber 2221 can abut against the other of the second inner core 22 and the second sleeve 121, thereby limiting the relative position of the second inner core 22 and the second sleeve 121 in the radial direction of the suspension component.

[0054] Therefore, the second inner core 22 serves as the core component of the second sub-suspension 12 and also plays a supporting and connecting role. The limiting rubber 2221 is set on one of the second inner core 22 and the second sleeve 121, and can abut against the other of the two. It can radially limit the relative position of the second inner core 22 and the second sleeve 121 in the suspension assembly, which is beneficial to increase the stability of the suspension assembly.

[0055] In addition, in this embodiment, as a preferred embodiment, refer to Figure 2 、 Figure 5 and Figure 7 As shown in the figure, there are multiple first main spring rubbers 112, spaced apart circumferentially around the first inner core 21. This arrangement helps more evenly absorb and disperse vibration energy from all directions. The first and second sub-mounts 11, 12 work together, making the suspension assembly more stable and reliable in complex vibration environments, effectively ensuring its superior performance.

[0056] In the specific structure, the number of the first main spring rubbers 112 in this embodiment can be three. Of course, the specific number of the first main spring rubbers 112 can also be designed and adjusted accordingly according to actual vibration reduction requirements, for example, it can be set to four or five.

[0057] In specific implementation, the first inner core 21 and the first sleeve 111 can be connected together by vulcanization of the first main spring rubber 112, and the first main spring rubber 112 and the limiting rubber 2221 are both made of rubber material. When the first inner core 21, the second inner core 22, the first sleeve 111 and the second sleeve 121 and other components are manufactured, the main material is aluminum or iron with a content of more than 70%.

[0058] Specifically, as a preferred embodiment, Figure 6 As shown in the figure, the second inner core 22 of this embodiment includes a second inner core body 221 and a limiting rubber mounting portion 222 provided on the second inner core body 221. The limiting rubber mounting portion 222 protrudes in the radial direction away from the second inner core body 221 along the radial direction of the suspension component, and a limiting rubber 2221 is provided on the limiting rubber mounting portion 222.

[0059] It is understood that the second inner core body 221 is used to provide the necessary support and connection functions. The provision of the limit rubber mounting portion 222 allows the limit rubber 2221 to be securely mounted on the second inner core 22 and to provide effective radial limiting for the suspension assembly, thereby ensuring that the suspension assembly remains stable under vibration or impact conditions. In specific implementations, the limit rubber 2221 is vulcanized and wrapped around the limit rubber mounting portion 222, thereby providing cushioning during the limiting process.

[0060] Furthermore, in this embodiment, as a preferred implementation form, Figure 6 As shown, there are multiple limiting rubber mounting parts 222 , which are arranged at circumferential intervals around the second inner core body 221 , and each limiting rubber mounting part 222 is provided with a limiting rubber 2221 .

[0061] Here, the limiting rubber mounting portion 222 on the second inner core 22 is arranged at circumferential intervals around the second inner core body 221, which helps to more evenly distribute the limiting force provided by the limiting rubber 2221, ensuring that the second inner core 22 can be stably supported and limited in multiple directions, thereby improving the overall stability and load-bearing capacity of the suspension assembly.

[0062] Specifically, the limiting rubber mounting portions 222 in this embodiment can be provided in four positions, distributed in a cross shape. Of course, in addition to being provided in four positions, the number can also be designed and adjusted accordingly based on actual needs, such as being provided in one, two, five, or six positions. Furthermore, in other embodiments, the limiting rubber mounting portion 222 can also be provided in a circular ring shape, so that it is sleeved on the second inner core body 221.

[0063] In addition, in this embodiment, as a preferred implementation form, Figure 3 As shown in , along the axial direction of the suspension assembly, each first main spring rubber 112 has a protruding portion 1121 that protrudes relative to the first inner core 21 toward the adjacent second sub-suspension 12. Furthermore, the limiting rubber mounting portion 222 and the limiting rubber 2221 both extend along the axial direction of the suspension assembly, with both ends of the limiting rubber mounting portion 222 and the limiting rubber 2221 respectively abutting against the protruding portions 1121 at either end.

[0064] Here, the presence of the protruding portion 1121 helps to increase the contact area of ​​the rubber between the first sub-suspension 11 and the second sub-suspension 12, thereby improving the connection stability and load-bearing capacity therebetween, and also enables the suspension assembly to have excellent vibration reduction performance in its own axial direction.

[0065] It should also be noted here that, in the above embodiment, the limiting rubber 2221 is provided on the second inner core 22 for explanation. It should be understood that, in other embodiments, the limiting rubber 2221 may not be provided on the second inner core 22, but may be provided on the second sleeve 121. For example, the limiting rubber 2221 may be specifically provided on the inner circumferential wall of the second sleeve 121, and it may protrude toward the second inner core 22 along the radial direction of the second sleeve 121, and it is also feasible to set it at a distance from the second inner core 22.

[0066] Furthermore, considering the stability requirement of the suspension assembly, in this embodiment, as a preferred implementation form, Figure 3 and Figure 7 As shown in FIG, the second sleeve 121 is integrated with any adjacent first sleeve 111 into a one-piece structure. This helps improve the rigidity and stability of the suspension assembly, reduces the number of connection points between adjacent sub-suspensions 1, and thus reduces the potential risk of loosening. This structure helps improve the load-bearing capacity of the suspension assembly, enabling it to cope with more complex vibration and shock environments.

[0067] In addition, it should be understood that, as another preferred embodiment, there are two second sleeves 121 in the second sub-suspension 12, the two second sleeves 121 are axially connected to the suspension component, and the two second sleeves 121 are respectively integrated with the adjacent first sleeves 111 into an integral structure.

[0068] It is worth mentioning that in this embodiment, the first sub-mount 11, the second sub-mount 12, and the further first sub-mount 11 of the suspension assembly can be press-fitted into the suspension bracket 4. Specifically, the structure of the suspension bracket 4 can refer to the prior art, such as the mounting hole 41 for mounting the suspension assembly and the connection hole 42 for connecting to the vehicle powertrain.

[0069] In addition, as a preferred embodiment, Figure 4 、 Figure 5 and Figure 6 As shown in , the anti-rotation structure 3 of this embodiment includes an anti-rotation protrusion 31 provided on one of the two adjacent inner cores, and an anti-rotation groove 32 provided on the other of the two adjacent inner cores, and the anti-rotation protrusion 31 is embedded in the anti-rotation groove 32.

[0070] At this point, it can be understood that the anti-rotation structure 3, including the anti-rotation protrusion 31 and the anti-rotation groove 32, can effectively prevent relative rotation between the inner cores, thereby improving the stability and reliability of the suspension assembly. At the same time, the anti-rotation structure 3 also has the advantages of low cost, simple manufacturing, and strong adaptability.

[0071] Furthermore, in this embodiment, as a preferred implementation, multiple anti-rotation structures 3 are provided, spaced apart around the circumference of the inner core. This arrangement helps to more evenly distribute the anti-rotation force provided by the anti-rotation structures 3, ensuring that the inner core is stably supported and limited in multiple directions, reliably preventing relative rotation between adjacent inner cores. This design also helps to improve the overall stability and load-bearing capacity of the suspension assembly.

[0072] In the specific structure, two anti-rotation structures 3 can be provided. That is, in this embodiment, anti-rotation protrusions 31 are respectively provided at both ends of the second inner core body 221 along the axial direction of the suspension assembly, and the anti-rotation protrusions 31 at each end are two arranged along the circumferential spacing of the second inner core body 221. At the same time, each first inner core 21 is provided with an anti-rotation groove 32 arranged corresponding to each anti-rotation protrusion 31 on the side facing the second inner core body 221. Of course, in addition to being provided with two anti-rotation structures 3, the anti-rotation structures 3 can also be designed and adjusted accordingly according to actual needs, for example, three or four anti-rotation structures can be provided.

[0073] In addition, in other embodiments, anti-rotation grooves 32 may be respectively provided at both ends of the second inner core body 221 along the axial direction of the suspension assembly, and each first inner core 21 is provided with an anti-rotation protrusion 31 arranged corresponding to each anti-rotation groove 32 on one side facing the second inner core body 221.

[0074] The suspension assembly of this embodiment utilizes multiple sub-suspensions 1, each of which can utilize rubber with different stiffnesses. This allows for a wide range of applications, meeting the varying stiffness requirements of the stop rubber 2221 and the main spring rubber, thereby enhancing the suspension assembly's flexibility and versatility. Furthermore, the provision of the anti-rotation grooves 32 and anti-rotation protrusions 31 effectively prevents adjacent sub-suspensions 1 from rotating about the assembly's axis, thereby ensuring the stability and reliability of the entire suspension assembly.

[0075] Example 2

[0076] This embodiment relates to a vehicle, in which the suspension assembly of the first embodiment is provided.

[0077] The vehicle of this embodiment adopts the suspension assembly of Example 1, which can meet the requirements of different stiffness of the limit rubber 2221 and the main spring rubber, which is beneficial to improving the flexibility and versatility of the suspension assembly. The setting of the anti-rotation groove 32 and the anti-rotation protrusion 31 can effectively prevent the adjacent sub-suspensions 1 from rotating around the axial direction of the assembly, thereby ensuring the stability and reliability of the entire suspension assembly.

[0078] 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.
