[0044] Embodiment 1

[0045] This embodiment relates to a suspension assembly, which comprises a mounting sleeve 1, a suspension bushing 4 arranged in the mounting sleeve 1, and a mounting bracket arranged on the mounting sleeve 1. An outer tube 401 of the suspension bushing 4 is provided with a groove 4012 for facilitating the reduction of the outer tube 401, and the suspension assembly is mounted on the sub-frame via the mounting bracket.

[0046] The suspension assembly of this embodiment is provided with a mounting sleeve 1 for mounting the suspension bushing 4, and the mounting sleeve 1 is mounted on the sub-frame through a mounting bracket, so that the mounting position of the suspension bushing 4 can be adjusted by adjusting the relative position of the mounting bracket on the sub-frame, thereby facilitating the installation flexibility of the suspension assembly on the sub-frame. In addition, by providing a slot 4012 on the outer tube 401 that is easy to reduce the diameter of the outer tube 401, it is convenient to reduce the diameter of the outer tube 401 during installation, thereby facilitating the installation of the suspension bushing 4 in the mounting sleeve 1, thereby improving the installation efficiency of the suspension bushing 4.

[0047] Based on the above overall introduction, an exemplary structure of the suspension assembly in this embodiment is as follows: Figures 1 to 3 As a preferred embodiment, the mounting bracket includes a first frame 2 disposed on the mounting sleeve 1, and a second frame 3 connected to the first frame 2, wherein the first frame 2 is connected to the second frame 3. In addition, the second frame 3 is provided with a connection portion connected to the sub-frame.

[0048] Here, the first frame 2 and the second frame 3 cooperate with each other, and the first frame 2 and the second frame 3 are connected, and the setting of the connecting part not only facilitates the installation and disassembly of the suspension assembly on the sub-frame, but also facilitates the loading and unloading between the first frame 2 and the second frame 3, thereby helping to reduce the maintenance cost of the suspension bushing 4 and the mounting bracket.

[0049] In specific implementation, the first frame 2 can be connected to the second frame 3 by screwing, and the connecting portion is connected to the sub-frame by screwing. The first frame 2 and the second frame 3 are connected by screwing, which is conducive to adjusting the relative position between the two, and thus to changing the flexibility of the suspension assembly installed on the sub-frame. The connecting portion connected to the sub-frame by screwing is provided on the second frame 3 and connected to the sub-frame, and the structure of the first frame 2 and the second frame 3 is simple, which is convenient for realizing the connection between the mounting sleeve 1 and the sub-frame.

[0050] In order to facilitate the adjustment of the installation position of the suspension assembly relative to the sub-frame, as a preferred embodiment, the connection position of the first frame body 2 and the second frame body 3 in the axial direction of the installation sleeve 1 is adjustable. Such a configuration is conducive to changing the position of the suspension assembly along the axial direction of the installation sleeve 1, and then changing the relative position on the sub-frame, and has good adjustment flexibility.

[0051] As a preferred embodiment, the first frame 2 and the second frame 3 are both arranged on two opposite sides of the mounting sleeve 1, which is conducive to improving the mounting firmness of the suspension assembly on the subframe. Figure 1 and Figure 4 As shown in the figure, the first frame 2 includes a top portion 201 and side portions 202 arranged on two opposite sides of the top portion 201, the side portions 202 are connected to the mounting sleeve 1, and the top portion 201 is screwed to the second frame 3. Here, the first frame 2 is roughly "U" shaped, the opening of the first frame 2 is arranged toward the mounting sleeve 1, and the two ends of the first frame 2 are respectively connected to the outer peripheral wall of the mounting sleeve 1. Here, the structure of the first frame 2 is simple, which is conducive to processing and molding.

[0052] In addition, the spacing between the two sides of the first frame 2 is gradually increased in the direction close to the installation sleeve 1, which is conducive to further improving the connection firmness between the first frame 2 and the installation sleeve 1. Furthermore, the top part 201 is extended along the axial direction of the installation sleeve 1 to facilitate screw connection with the second frame 3.

[0053] like Figure 1 As shown in , the second frame 3 includes a longitudinal portion 301 extending along the axial direction of the mounting sleeve 1, and a transverse portion 302 extending along the radial direction of the mounting sleeve 1, the longitudinal portion 301 is connected to the first frame 2, and the connecting portion is arranged on the transverse portion 302. Here, the arrangement of the longitudinal portion 301 and the transverse portion 302 on the second frame 3 has a high structural strength, and the top portion 201 is connected to the second frame 3, which is convenient for arrangement and implementation.

[0054] As a preferred embodiment, the longitudinal portion 301 is provided with a plurality of connection holes 3011, which are arranged at intervals along the extension direction of the longitudinal portion 301 and are used to connect with the first frame 2. The top portion 201 is screwed to the second frame 3. In order to adjust the position of the second frame 3 relative to the first frame 2, two studs 203 arranged at intervals are provided on the top portion 201, and each stud 203 extends radially outward from the mounting sleeve 1 and passes through the top portion 201. The number of connection holes 3011 can be Figure 1 As shown in the four, the connection between the second frame 3 and the first frame 2 can be achieved by inserting two studs 203 into two different connection holes 3011 and then screwing with nuts.

[0055] In addition, by changing the position of the stud 203 passing through the connection hole 3011, the connection position of the first frame 2 and the second frame 3 in the axial direction of the installation sleeve 1 can be changed, so that it can be adjusted according to the installation requirements of the suspension assembly on the subframe, and has good installation flexibility. The arrangement of the stud 203 here is conducive to arrangement and implementation, and the effect of matching with the connection hole 3011 is good.

[0056] like Figure 1 As shown in , the above-mentioned connection part is provided in the mounting hole 3021 on the transverse part 302, and the second frame 3 is installed on the sub-frame by screwing through the bolts and nuts on the second frame 3 and the sub-frame. The structure of the mounting hole 3021 here is simple and easy to process and form. For example, there are two mounting holes 3021 arranged at intervals on each transverse part 302, and the transverse part 302 is provided with a first reinforcing rib 3022 located between the two mounting holes 3021 and extending along the extension direction of the transverse part 302. The cooperation of the two mounting holes 3021 is conducive to improving the mounting strength of the second frame 3 on the sub-frame, and the provision of the first reinforcing rib 3022 is conducive to further improving the connection reliability between the second frame 3 and the sub-frame.

[0057] As shown in the figure, in order to further improve the structural strength of the second frame 3, side flanges 303 extending outward are respectively provided on both sides of the junction of the longitudinal portion 301 and the transverse portion 302. The provision of the side flanges 303 here is conducive to increasing the connection area between the second frame 3 and the sub-frame, thereby improving the connection reliability between the two.

[0058] The second bracket in this embodiment can be arranged on the crossbeam or longitudinal beam of the subframe according to the use requirements. By changing the position of the suspension assembly on the crossbeam or longitudinal beam, the flexibility of the suspension assembly installation is improved, and it can be applied to the subframes of different models.

[0059] Specifically, when the suspension assembly is installed on the crossbeam of the subframe, the position of the suspension bushing 4 in the height direction and the left-right direction of the vehicle can be adjusted by adjusting the position of the second frame 3 in the height direction and the left-right direction of the crossbeam. And by adjusting the connection position of the first frame 2 and the second frame 3 in the axial direction of the installation sleeve 1, the position of the suspension bushing 4 in the front-rear direction of the vehicle can be adjusted, which further facilitates the installation of the suspension assembly on crossbeams of different specifications.

[0060] Similarly, when the suspension assembly is installed on the longitudinal beam of the subframe, the position of the suspension bushing 4 in the height direction and the front-rear direction of the vehicle can be adjusted by adjusting the position of the second frame 3 in the height direction and the left-right direction of the cross beam. And by adjusting the axial connection position of the first frame 2 and the second frame 3 in the installation sleeve 1, the position of the suspension bushing 4 in the left-right direction of the vehicle can be adjusted, which further facilitates the installation of the suspension assembly on longitudinal beams of different specifications.

[0061] Another implementation method of the mounting bracket in this embodiment is as follows Figure 5 As shown in , the mounting bracket here does not need the cooperation of the first frame 2 and the second frame 3. Specifically, the mounting bracket includes a main board 5, side panels 6 arranged on two opposite sides of the main board 5, and an outer flange 601 is provided on the side panel 6. Among them, a through hole is provided on the main board 5, and the mounting sleeve 1 is inserted into the through hole and connected to the main board 5 by welding, and the outer flange 601 is connected to the sub-frame. Among them, the through hole on the main board 5 in the mounting bracket is conducive to the arrangement of the mounting sleeve 1, and the setting of the outer flange 601 is conducive to the connection with the sub-frame and to improving the structural strength of the side panel 6.

[0062] In terms of specific structure, the through hole is located in the middle of the main board 5. In order to improve the installation effect of the mounting sleeve 1 on the main board 5, an annular protrusion 501 is provided on the main board 5 along the circumferential outward protrusion of the through hole. The provision of the annular protrusion 501 is conducive to extending the length of the through hole, increasing the connection area between the main board 5 and the mounting sleeve 1, and thus facilitating the improvement of the connection firmness of the mounting sleeve 1 on the mounting bracket.

[0063] Still refer to Figure 5 As shown in , the side panels 6 on both sides are tilted so that the distance between the two side panels 6 gradually increases in the direction away from the main board 5, which is conducive to improving the stability of the mounting bracket and the sub-frame in the connected state. Further, the side panels 6 can also be provided with second reinforcing ribs 602 extending along the extending direction of the side panels 6 to the outer flange 601, so as to further improve the structural strength of the side panels 6 and the connection strength between the outer flange 601 and the sub-frame.

[0064] In addition, the main board 5 and the two side boards 6 are preferably formed in one piece to improve processing and assembly efficiency and have a high structural strength. Both sides of the main board 5 and each side board 6 in the width direction are provided with folded reinforcing flanges 502 to enhance the overall structural strength of the mounting bracket. The reinforcing flanges 502 have a simple structure, are easy to arrange and implement, and have a good use effect.

[0065] The mounting bracket in this embodiment can be arranged on the crossbeam or longitudinal beam of the subframe according to the use requirements. By changing the position of the suspension assembly on the crossbeam or longitudinal beam, the flexibility of the suspension assembly installation is improved, and it can be applied to the subframes of different models.

[0066] Specifically, when the suspension assembly is installed on the crossbeam of the subframe, the position of the suspension bushing 4 in the height direction and the left-right direction of the vehicle can be adjusted by adjusting the positions of the two side plates 6 in the height direction and the left-right direction of the crossbeam. Similarly, when the suspension assembly is installed on the longitudinal beam of the subframe, the position of the suspension bushing 4 in the height direction and the front-back direction of the vehicle can be adjusted by adjusting the positions of the two side plates 6 in the height direction and the front-back direction of the longitudinal beam.

[0067] The above two structural forms of the mounting brackets in this embodiment are both conducive to achieving the compatibility of the subframe assembly and the powertrain of different models on the same platform, and to ensuring the maximum platformization of the subframe and subassembly, thereby solving the problem of the current subframe assembly and various front / rear welded crossbeam subassemblies and suspension adaptation, thereby reducing the types of product development, reducing the development and reliability verification costs, and improving the platformization rate of the subframe body. In addition, the suspension bushing 4 and the mounting bracket and the subframe crossbeam subassembly are assembled by screw connection, welding and integrated press fitting, which is conducive to improving the convenience of after-sales maintenance, thereby reducing the man-hours and costs of after-sales maintenance.

[0068] As a preferred embodiment, the structure of the suspension bushing 4 in this embodiment is as follows: Figures 6 to 8As shown in , the suspension bushing 4 includes an inner tube 403, an outer tube 401 sleeved in the inner tube 403, and a rubber body 402 integrally vulcanized and formed between the inner tube 403 and the outer tube 401. The two ends of the inner tube 403 are both extended out of the two ends of the outer tube 401, and one end of the outer tube 401 is provided with a radially outwardly convex limiting ring 4011, and the above-mentioned slot 4012 is also set through the limiting ring 4011. The limiting ring 4011 here can play a limiting role when the suspension bushing 4 is installed in the installation sleeve 1, so as to ensure that the suspension bushing 4 is installed in place.

[0069] In this embodiment, the structure of the suspension bushing 4 is simple, and the one-piece molding processing method is conducive to reducing the types and quantity of parts, streamlining the redundancy of production processes, and reducing R&D cost investment. In addition, compared with the traditional split vulcanization solution, the one-piece vulcanization molding method is also conducive to reducing the types and quantities of parts, further streamlining the redundancy of production processes, and reducing R&D cost investment.

[0070] like Figure 7 As shown in , the above-mentioned slot 4012 penetrates the outer tube 401 along the thickness direction of the outer tube 401, and the slot 4012 penetrates from one end of the outer tube 401 axially to the other end. Such a configuration is conducive to reducing the diameter of the outer tube 401, and while ensuring that the suspension bushing 4 is able to escape from the mounting sleeve 1, it is also conducive to improving the smoothness of assembly, reducing the degree of deformation between metal components, and improving the product qualification rate. At the same time, the slot 4012 has a simple structure and is easy to process and form.

[0071] In this embodiment, the width of the slot 4012 is between 2 mm and 4 mm to ensure the convenience of installing the suspension bushing 4 in the installation sleeve 1 and to facilitate the use performance of the suspension bushing 4. In specific implementation, the width of the slot 4012 can be, for example, 2 mm, 3 mm or 4 mm. When the suspension bushing 4 is press-fitted into the installation sleeve 1, the width of the slot 4012 can be changed to 0 mm, that is, a certain initial stiffness is obtained in the axial direction, thereby facilitating the improvement of the installation reliability of the suspension bushing 4 on the installation sleeve 1.

[0072] As a preferred embodiment, one end of the rubber body 402 of the suspension bushing 4 has a first protruding portion 4021 protruding relative to the outer tube 401, and the draft angle of the free end of the first protruding portion 4021 is between 58° and 62°. The edge of the first protruding portion 4021 is provided with a plurality of notches 4022, and the plurality of notches 4022 are arranged at intervals along the circumference of the suspension bushing 4. Here, the first protruding portion 4021 on the rubber body 402 and the setting of the draft angle of its free end are conducive to the rapid attenuation of the excitation energy, thereby improving the NVH and handling performance of the whole vehicle. The setting of the plurality of notches 4022 on the first protruding portion 4021 is conducive to further rapid attenuation of the excitation energy.

[0073] In terms of specific structure, the first protrusion 4024 and the limiting protrusion 4024 are located at the same end. The draft angle of the free end of the first protruding portion 4021 can be, for example, 58°, 60° or 62°. A plurality of notches 4022 are arranged along the axial direction of the rubber body 402 and penetrate the first protruding portion 4021. The cross section of the notch 4022 can be semicircular as shown in the figure, which is conducive to the molding of the notch 4022 and has a better use effect.

[0074] In addition, if Figure 7 As shown in the figure, the other end of the rubber body 402 of the suspension bushing 4 has a second protruding portion 4023 protruding relative to the outer tube 401, and the draft angle of the free end of the second protruding portion 4023 is between 28° and 32°. The second protruding portion 4023 is provided with a protrusion 4024, which extends from the end face of the second protruding portion 4023 to the side face, and the protrusion 4024 is arranged in a plurality of intervals along the circumference of the second protruding portion 4023. Here, the setting of the second protruding portion 4023, the protrusion 4024 and the draft angle of the free end of the second protruding portion 4023 is also conducive to the rapid attenuation of the excitation energy.

[0075] To facilitate the distinction, such as Figure 7 As shown in the figure, the draft angle of the free end of the first protruding portion 4021 is called the first draft angle α, and the draft angle of the free end of the second protruding portion 4023 is called the second draft angle β. In specific implementation, the draft angle of the free end of the second protruding portion 4023 can be, for example, 28°, 30° or 32°. In addition, the protrusion 4024 extends from the free end of the second protruding portion 4023 to the end of the outer tube 401 along the axial direction of the rubber body 402. The cooperation of multiple protrusions 4024 is conducive to further improving the strength of the suspension bushing 4.

[0076] When the vehicle is driving in harsh conditions, the low-frequency vibration and macro-roughness of the road surface generate road excitation force, which is transmitted to the suspension assembly through the axle head, suspension, and subframe. At this time, in the axial direction of the suspension bushing 4, the draft angle of the free end of the first protrusion 4021 and the setting of the draft angle of the free end of the second protrusion 4023 are beneficial to compressing the rubber body 402, and at the same time, it is beneficial to change the mode of the suspension system in the front and rear directions of the vehicle (including the drive axle), thereby achieving rapid attenuation of the excitation energy, and further helping to improve the NVH and handling performance of the vehicle.

[0077] In addition, according to the driving conditions and the (low-frequency vibration) frequency of the road surface, parameters such as the width of the slot 4012 in the outer tube 401, the notch 4022 and the draft angle on the first protruding part 4021, and the protrusion 4024 and the draft angle on the second protruding part 4023 can be adjusted to facilitate changing the mass and stiffness of the suspension bushing 4, thereby achieving adjustable frequency and quickly attenuating the excitation energy transfer.

[0078] The suspension assembly of this embodiment, by optimizing its own structure, not only has the advantages of simple structure and easy implementation, but also is easy to apply to subframes of different specifications, and has strong adaptability and compatibility, which is conducive to the platformization and serialization of suspension assembly products. In addition, the suspension assembly is also conducive to reducing the types and number of parts, thereby helping to reduce production cost investment. At the same time, the suspension assembly is also conducive to quickly attenuating the transmission of bad road excitation energy of the whole vehicle, thereby improving the NVH and handling performance quality of the whole vehicle.

[0079] In addition, the present embodiment also relates to a vehicle, on which the suspension assembly as described above is provided.

[0080] During specific implementation, the suspension assembly is located on a subframe of the vehicle, and the subframe here may be a front subframe and a rear subframe on the vehicle.

[0081] The vehicle of this embodiment, by providing the suspension assembly as described above, is not only conducive to improving assembly efficiency and assembly flexibility, but also conducive to reducing production costs.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
