Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle parts, and in particular to a suspension bushing. The utility model also relates to a suspension assembly provided with the suspension bushing, and a vehicle provided with the suspension assembly. Background Art
[0002] With the continuous development of society, automobiles have become an indispensable part of people's lives as a means of transportation. Furthermore, the powertrain in a car primarily consists of the engine and transmission. Existing car bodies and powertrains are generally rigidly connected, causing vibration and noise during operation. The suspension system, a crucial component for reducing vibration and shock, connects between the engine and the frame, supporting and isolating the engine. Its vibration isolation performance directly impacts the vibration and noise levels of the entire vehicle.
[0003] At present, most suspension systems use rubber suspension for vibration reduction. It can form a shock absorber with the powertrain to absorb road vibrations and reduce the bumpy feeling of the vehicle. In addition, its smaller limit gap size can reduce the time and amplitude of the powertrain shaking inside the cabin when the vehicle is bumpy.
[0004] However, most rubber suspensions use an integrated rubber structure, which is limited by the integrated mold and cannot be designed as a pre-compression structure. During vehicle driving, the rubber is prone to excessive deformation or fatigue, resulting in rubber damage, which is not conducive to improving the vehicle's ride comfort. Utility Model Content
[0005] In view of this, the present invention aims to provide a suspension bushing to improve the ride comfort of a vehicle.
[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:
[0007] A suspension bushing comprises an outer tube, an inner tube, a rubber main spring connected between the outer tube and the inner tube, and a fluid storage portion; the rubber main spring is provided with a receiving space, the fluid storage portion is located in the receiving space and is installed on the rubber main spring, and the fluid storage portion is provided with a fluid storage cavity for storing fluid.
[0008] Furthermore, a plurality of fluid storage cavities are provided in the fluid storage portion, and a fluid inlet for filling the fluid into each of the fluid storage cavities is provided on the fluid storage portion.
[0009] Furthermore, the plurality of fluid storage cavities are arranged in sequence in a horizontal direction perpendicular to the axial direction of the outer tube; each of the fluid storage cavities is in a long strip shape, and the length direction of each of the fluid storage cavities extends along the axial direction of the outer tube.
[0010] Furthermore, a communication channel is provided between any adjacent fluid storage cavities, and the fluid inlet is communicated with any of the fluid storage cavities.
[0011] Furthermore, there are a plurality of communication channels between any adjacent fluid storage chambers, and the plurality of communication channels are arranged at intervals along the axial direction of the outer tube.
[0012] Furthermore, the rubber main spring includes an outer tube connecting portion connected to the outer tube, an inner tube connecting portion connected to the inner tube, and an inner-outer tube connecting portion connecting the outer tube connecting portion and the inner tube connecting portion, wherein the accommodating space is formed between the outer tube connecting portion and the inner tube connecting portion;
[0013] The fluid storage portion is fixed on the outer tube connection portion or the inner tube connection portion, and the fluid storage portion is located above the inner tube along the up-down direction of the vehicle.
[0014] Furthermore, the outer tube connecting part is provided with an outer tube limiting part protruding into the accommodating space, and the outer tube connecting part is connected to the fluid storage part through the outer tube limiting part; the inner tube connecting part is provided with an inner tube limiting part protruding into the accommodating space, and the inner tube connecting part can be pressed against the fluid storage part through the inner tube limiting part; the outer tube limiting part and the inner tube limiting part are placed on the upper and lower sides of the fluid storage part.
[0015] Furthermore, there are multiple inner tube limiting portions, and the multiple inner tube limiting portions are arranged in sequence along a direction orthogonal to the axial direction of the outer tube.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] The suspension bushing described in the utility model is applied to the suspension assembly to realize the pre-compression function of the suspension assembly and improve the application reliability of the suspension assembly. After the suspension assembly integrated with the suspension bushing is installed on the vehicle body, the fluid storage cavity can be filled with fluid. The operation is convenient and the assembly is simple. After the fluid storage part is filled with fluid, a damping effect can be generated, thereby improving the vibration reduction performance and impact resistance of the suspension. When applied to the vehicle body, it is beneficial to improve the ride comfort of the vehicle.
[0018] Secondly, the multiple fluid storage chambers can be used to store different fluids. The fluid inlets facilitate filling the fluid storage portion with fluid, with each fluid inlet connected to a specific fluid storage chamber. The fluid storage chambers are arranged horizontally, perpendicular to the axial direction of the outer tube, facilitating overall layout. Each fluid storage chamber is elongated and extends along the axial direction of the outer tube, increasing fluid storage capacity.
[0019] Furthermore, the provision of connecting channels allows fluid to flow or transfer between these fluid storage chambers, balancing the fluid pressure within each chamber and achieving a good damping effect. Providing multiple connecting channels not only facilitates the back-and-forth flow of fluid between adjacent fluid storage chambers, but also, by arranging these connecting channels along the axial spacing of the outer tube, the unconnected portions between adjacent fluid storage chambers create significant resistance to fluid flow, resulting in excellent damping performance for the fluid storage unit.
[0020] In addition, the fluid storage part is fixed on one of the outer tube connection part and the inner tube connection part, which can produce better damping performance. The fluid storage part is located above the inner tube, which can be conveniently arranged, so that the fluid storage part has a larger fluid storage space, thereby facilitating the improvement of the damping performance of the fluid storage part. When used in the suspension assembly, it can better realize the pre-compression function of the suspension assembly, and the fluid filling is more convenient.
[0021] The fluid storage portion is disposed between the outer tube stopper and the inner tube stopper. This not only facilitates the arrangement of the fluid storage portion but also allows for positioning of the fluid storage portion in the vertical direction of the vehicle, thereby ensuring its damping effect. Furthermore, the fluid storage portion cooperates with the outer and inner tube stoppers in the vertical direction of the vehicle, further enhancing the bushing assembly's vibration damping performance. Providing multiple inner tube stoppers, arranged sequentially in a direction perpendicular to the axial direction of the outer tube, reduces the contact area between the inner tube stopper and the fluid storage portion. Furthermore, the inner tube stopper can correspond to a portion of the fluid storage cavity, thereby enhancing the damping performance of the fluid storage portion.
[0022] In addition, another object of the present invention is to provide a suspension assembly, comprising a suspension bracket having a bushing mounting hole, and the suspension bushing as described above mounted in the bushing mounting hole.
[0023] The suspension assembly described in the present invention can realize the pre-compression function of the suspension assembly by adopting the above-mentioned suspension bushing, thereby improving the application reliability of the suspension assembly. Moreover, after the fluid storage part is filled with fluid, a damping effect can be generated, thereby improving the vibration reduction performance and impact resistance of the suspension, and further helping to improve the ride comfort of the vehicle.
[0024] In addition, another object of the present invention is to provide a vehicle, on which the suspension assembly as described above is provided.
[0025] The vehicle described in 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

For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.
[0041] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0042] Example 1
[0043] This embodiment relates to a suspension bushing that can realize the pre-compression function of the suspension assembly and improve the ride comfort of the vehicle. Figures 1 to 5 As shown in FIG, the suspension bushing of this embodiment includes an outer tube 1 , an inner tube 2 , a rubber main spring 3 connected between the outer tube 1 and the inner tube 2 , and a fluid storage portion 41 .
[0044] The rubber main spring 3 is provided with a receiving space 4 , the fluid storage portion 41 is in the receiving space 4 and is mounted on the rubber main spring 3 , and the fluid storage portion 41 is provided with a fluid storage cavity 411 for storing fluid.
[0045] At this point, it can be understood that the suspension bushing described in the present invention, when applied to the suspension assembly, can realize the pre-compression function of the suspension assembly and improve the application reliability of the suspension assembly. After the suspension assembly integrated with the suspension bushing is installed on the vehicle body, the fluid storage chamber 411 can be filled with fluid. The operation is convenient and the assembly is simple. After the fluid storage part 41 is filled with fluid, a damping effect can be generated, thereby improving the vibration reduction performance and impact resistance of the suspension. When applied to the vehicle body, it is beneficial to improve the ride comfort of the vehicle.
[0046] It should be noted that in this embodiment, only one fluid storage chamber 411 can be provided. When the fluid filled in fluid storage chamber 411 is air, it can form a structure similar to an air spring, thereby achieving the required vibration reduction performance of the suspension assembly. It should also be understood that the filling fluid can be other media besides air, such as nitrogen, liquid, etc.
[0047] In practice, the fluid storage portion 41 in this embodiment can be made of polyurethane (PU), polyvinyl chloride (PVC), or thermoplastic polyurethane (TPU), all of which are well known to those skilled in the art. Furthermore, the inner and outer tube connection portion 33 in this embodiment can be configured with reference to conventional connecting rib structures, and will not be further described here.
[0048] It is worth mentioning that in this embodiment, the inner tube 2 of the suspension bushing is used to cooperate with the supporting arm 52. Specifically, the supporting arm 52 has an insertion portion 521 that is inserted into the inner tube 2. The supporting arm 52 is also provided with a connecting portion 522 for connecting to the powertrain. The connecting portion 522 specifically comprises three connecting holes 5221 to facilitate connection with the powertrain. It should be understood that the number of connecting holes 5221 can be other than three, such as two or four.
[0049] Based on the above overall introduction, in this embodiment, as a preferred implementation form, as Figure 4 and Figure 5 As shown in FIG, the fluid storage unit 41 is provided with a plurality of fluid storage chambers 411. Here, the plurality of fluid storage chambers 411 are provided in the fluid storage unit 41 to store different fluids. Furthermore, the fluid storage unit 41 is provided with a fluid inlet 412 for filling each fluid storage chamber 411 with fluid. Thus, the provision of the fluid inlet 412 facilitates filling the fluid storage unit 41 with fluid.
[0050] It is worth mentioning that the number of fluid storage chambers 411 in this embodiment can be set to five. Of course, in addition to being set to five, the number can also be designed and adjusted accordingly according to actual storage needs, for example, it can be set to three or eight.
[0051] In the specific structure, the fluid storage chambers 411 are not connected to each other. Therefore, multiple fluid inlets 412 can be set, and each fluid inlet 412 corresponds to each fluid storage chamber 411 one by one, so that each fluid inlet 412 is connected to a specific fluid storage chamber 411 to facilitate filling the specific fluid storage chamber 411 with fluid.
[0052] In other embodiments, the multiple fluid storage chambers 411 may be filled with different fluids, wherein each fluid is filled in one or more fluid storage chambers 411. Taking the five fluid storage chambers 411 of this embodiment as an example, any one fluid storage chamber 411 is filled with air, and any two of the remaining fluid storage chambers 411 are filled with nitrogen, and the last two fluid storage chambers 411 are filled with liquid.
[0053] Furthermore, in this embodiment, as a preferred implementation form, Figure 4 and Figure 5 As shown in , multiple fluid storage chambers 411 are arranged in sequence in the horizontal direction along a direction perpendicular to the axial direction of the outer tube 1. Here, the fluid storage chambers 411 are arranged in sequence in the horizontal direction, and the arrangement direction is perpendicular to the axial direction of the outer tube 1, which facilitates the overall layout.
[0054] At the same time, each fluid storage cavity 411 is elongated, and the length direction of each fluid storage cavity 411 extends along the axial direction of the outer tube 1. The elongated shape of each fluid storage cavity 411 and the extension of each fluid storage cavity 411 along the axial direction of the outer tube 1 help increase the fluid storage capacity.
[0055] In the specific structure, there are fluid channels and unconnected parts between any two adjacent fluid storage chambers 411. When multiple fluid storage chambers 411 are connected in sequence, the fluid flows repeatedly between the multiple fluid storage chambers 411. The unconnected parts can increase the resistance to fluid flow, and when the fluid flows, it gradually enters the fluid storage chamber 411 with lower pressure, which has a better damping effect.
[0056] It should be noted that the unconnected portion in this embodiment can be formed by partially bonding the upper and lower surfaces of the fluid storage chamber 411 to form an internally hollow isolation column 413, or the entire portion can be bonded together. Of course, in addition to bonding, other common connection methods can also be used, such as welding, fusion connection, etc.
[0057] In the specific structure, nine isolation columns 413 are arranged at axial intervals along the outer tube 1 between any adjacent fluid storage chambers 411. Of course, the specific number of isolation columns 413 can also be designed and adjusted accordingly according to actual needs, such as eight or ten.
[0058] At the same time, in this embodiment, as a preferred implementation form, a communication channel is provided between any adjacent fluid storage chambers 411, and the fluid inlet 412 is connected to any fluid storage chamber 411. Here, a communication channel is provided between any adjacent fluid storage chambers 411, allowing fluid to flow or transfer between these fluid storage chambers 411. This design can be used to balance the fluid pressure in different fluid storage chambers 411 and has a good damping effect.
[0059] It is worth mentioning that the fluid storage chambers 411 in this embodiment can also be interconnected. In this case, a fluid inlet 412 is provided to connect with any fluid storage chamber 411 , and fluid is filled into the corresponding fluid storage chamber 411 through the fluid inlet 412 , so that the fluid flows into each fluid storage chamber 411 .
[0060] Specifically, in this embodiment, as a preferred implementation form, there are multiple communication channels between any adjacent fluid storage chambers 411. The advantage of such an arrangement is that it facilitates the back and forth flow of fluid between adjacent fluid storage chambers 411.
[0061] At the same time, multiple communication channels are arranged at intervals along the axial direction of the outer tube 1. In this way, the isolation columns 413 between adjacent fluid storage chambers 411 can generate greater resistance to the flow of fluid, so that the fluid storage portion 41 has excellent damping performance.
[0062] During specific implementation, the number of connecting channels can be designed and adjusted accordingly according to actual needs. In this embodiment, it is preferred to set the number of connecting channels between any adjacent fluid storage chambers 411 to ten, that is, connecting channels are provided between two adjacent isolation columns 413, and between the edge of the fluid storage part 41 and the isolation column 413 close to the edge.
[0063] In this embodiment, the rubber main spring 3 includes an outer tube connecting portion 31 connected to the outer tube 1, an inner tube connecting portion 32 connected to the inner tube 2, and an inner and outer tube connecting portion 33 connecting the outer tube connecting portion 31 and the inner tube connecting portion 32 together.
[0064] As a preferred embodiment, the aforementioned accommodating space 4 is formed between the outer tube connecting portion 31 and the inner tube connecting portion 32. The accommodating space 4 passes through the rubber main spring 3 along the axial direction of the suspension bushing. The fluid storage portion 41 is specifically fixed on the outer tube connecting portion 31 or the inner tube connecting portion 32, which can produce better damping performance.
[0065] In a preferred embodiment, the fluid storage portion 41 is located above the inner tube 2 along the up-down direction of the entire vehicle, and the fluid storage portion 41 can be conveniently arranged so that the fluid storage portion 41 has a larger fluid storage space, thereby facilitating improving the damping performance of the fluid storage portion 41. When applied to the suspension assembly, it can better realize the pre-compression function of the suspension assembly, and fluid filling is more convenient.
[0066] Furthermore, as a preferred embodiment, Figure 2 As shown in FIG, the outer tube connection portion 31 of this embodiment is provided with an outer tube stopper 311 protruding into the accommodating space 4, and the outer tube connection portion 31 is connected to the fluid storage portion 41 via the outer tube stopper 311. At the same time, the inner tube connection portion 32 is provided with an inner tube stopper 321 protruding into the accommodating space 4, and the inner tube connection portion 32 can be pressed against the fluid storage portion 41 via the inner tube stopper 321.
[0067] Here, a fluid storage part 41 is arranged between the outer tube connecting part 31 and the inner tube connecting part 32. On the one hand, it facilitates the arrangement of the fluid storage part 41. On the other hand, the outer tube limiting part 311 and the inner tube limiting part 321 can limit the fluid storage part 41 in the upper and lower directions of the entire vehicle respectively, which is conducive to ensuring the damping effect of the fluid storage part 41.
[0068] The outer tube limiter 311 and the inner tube limiter 321 are respectively placed on the upper and lower sides of the fluid storage portion 41. With this arrangement, the fluid storage portion 41 can cooperate with the outer tube limiter 311 and the inner tube limiter 321 in the vertical direction of the vehicle, thereby making the vibration reduction performance of the bushing assembly more excellent. In specific implementation, the support arm 52 moves upward, driving the inner tube limiter 321 to compress the fluid storage portion 41, hitting the outer tube limiter 311, thereby limiting the movement of the support arm 52.
[0069] It should be understood that, in this embodiment, the outer tube limiting portion 311 can also be set to multiple, so that the multiple outer tube limiting portions 311 are arranged in sequence along a direction orthogonal to the axial direction of the outer tube 1, and the specific number of the outer tube limiting portions 311 can be designed and adjusted accordingly according to actual needs, such as three or four.
[0070] In a specific structure, the fluid storage portion 41 can be fixed to the outer tube limiting portion 311 by bonding, fusing, vulcanization, or the like, and only contacts the inner tube limiting portion 321. In a specific implementation, the supporting arm 52 moves upward, driving the inner tube limiting portion 321 upward, causing it to abut against the lower surface of the fluid storage portion 41, thereby limiting the position of the supporting arm 52.
[0071] It should be understood that in other embodiments, the fluid storage portion 41 may be fixed to the inner tube limiting portion 321 by bonding, fusing, vulcanization, or the like, and only contacts the outer tube limiting portion 311. In specific implementations, the supporting arm 52 moves upward, driving the inner tube limiting portion 321 and the fluid storage portion 41, so that the upper surface of the fluid storage portion 41 abuts against the outer tube limiting portion 311, thereby limiting the position of the supporting arm 52.
[0072] In addition, the upper and lower surfaces of the fluid storage part 41 are fixedly connected to the outer tube limiting part 311 and the inner tube limiting part 321 respectively, which can also achieve the limitation of the support arm 52. It should be noted that the fluid cannot be filled too full at this time.
[0073] Furthermore, in this embodiment, as a preferred implementation form, Figure 2 As shown, there are multiple inner tube stoppers 321, which are arranged in sequence along a direction perpendicular to the axial direction of the outer tube 1. This arrangement reduces the contact area between the inner tube stoppers 321 and the fluid storage portion 41. Furthermore, the inner tube stoppers 321 can correspond to a portion of the fluid storage chamber 411, thereby improving the damping performance of the fluid storage portion 41.
[0074] In specific structures, such as Figure 3 As shown in FIG, in this embodiment, two inner tube limiting portions 321 may be provided, one corresponding to the second fluid storage chamber 411 and the other corresponding to the fourth fluid storage chamber 411. Of course, the number of inner tube limiting portions 321 may also be designed and adjusted according to actual needs, for example, three or four.
[0075] When the support arm 52 moves upward, the second fluid storage chamber 411 and the fourth fluid storage chamber 411 are compressed, causing the fluid in the chamber to flow into the first, third and fifth fluid storage chambers 411 through the connecting channels, thereby generating greater resistance to the flow of the fluid and improving the damping performance of the fluid storage part 41.
[0076] In summary, the suspension bushing of this embodiment adopts the above design. By securely attaching the fluid storage portion 41 to the outer tube stopper 311, filling the fluid storage chamber 411 with fluid, and sealing the fluid inlet 412, the fluid storage portion 41 produces a damping effect. Simultaneously, when the support arm 52 moves upward, it drives the inner tube stopper 321 to compress the corresponding fluid storage chamber 411, allowing the fluid within the chamber to flow through the connecting channel to the adjacent fluid storage chamber 411. This enhances the damping performance of the fluid storage portion 41, thereby improving the vibration reduction and impact resistance of the suspension. When applied to a vehicle body, this can help enhance the ride comfort of the vehicle.
[0077] Example 2
[0078] This embodiment relates to a suspension assembly, including a suspension bracket 51 having a bushing mounting hole, and the suspension bushing of the first embodiment installed in the bushing mounting hole. The structure of the suspension bracket 51 can refer to the prior art.
[0079] The suspension assembly described in the present invention can realize the pre-compression function of the suspension assembly by adopting the above-mentioned suspension bushing, thereby improving the application reliability of the suspension assembly. Moreover, after the fluid storage part 41 is filled with fluid, a damping effect can be generated, thereby improving the vibration reduction performance and impact resistance of the suspension assembly, thereby helping to improve the ride comfort of the vehicle.
[0080] In specific implementation, before the suspension assembly is installed on the vehicle, the fluid storage part 41 does not need to be filled with fluid, and the fluid storage part 41 is in a natural state. After the suspension assembly is installed on the vehicle, the fluid is filled, and then the fluid inlet 412 is sealed so that it cannot be opened.
[0081] For example, preferably, after loading, the support arm 52 is pressed downward under the gravity of the power assembly, and the gap between the outer tube limit portion 311 and the inner tube limit portion 321 increases, and the increase is usually between 3mm and 7mm, such as 3mm, 5mm, and 7mm. After the fluid storage portion 41 is filled with fluid, the thickness of the fluid storage portion 41 increases, and the gap between the lower surface of the fluid storage portion 41 and the inner tube limit portion 321 is preferably between 0mm and 3mm, such as 0mm, 1.5mm, and 3mm.
[0082] In addition, this embodiment also provides a vehicle, on which the above-mentioned suspension assembly is provided.
[0083] The vehicle of this embodiment has the technical advantages of the above-mentioned suspension assembly, which will not be described in detail here.
[0084] 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.
