For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] This embodiment relates to a suspension assembly, including a suspension bushing 1 and a connecting bracket 2 connected to each other. The suspension bushing 1 includes an outer tube 101 for connecting to a subframe, an inner core 102 arranged in the outer tube 101, and a rubber body 103 connected between the outer tube 101 and the inner core 102, and the inner core 102 is provided with a connecting structure convexly arranged relative to the outer tube 101. The connecting bracket 2 is used to connect to the powertrain and has a convex connecting portion 203, which is connected to the top of the connecting structure along the radial direction of the inner core 102.

[0044] The suspension assembly of this embodiment connects the connecting portion 203 of the connecting bracket 2 to the top of the connecting structure along the radial direction of the inner core 102. Therefore, when the connection point between the connecting portion 203 and the connecting structure is loosened or broken, the connecting portion 203 can be supported by the connecting structure to prevent the power assembly from continuing to fall, thereby effectively ensuring the safety of the vehicle. At the same time, the connecting portion 203 is connected to the connecting structure along the radial direction of the inner core 102, and will not affect the assembly between the two.

[0045] Based on the above overall introduction, an exemplary structure of the suspension assembly of this embodiment is referred to as Figure 1 As shown in the figure, the overall structure of the suspension bushing 1 is the same as that of the prior art. As described above, it includes an outer tube 101 for connecting to a subframe, an inner core 102 disposed in the outer tube 101, and a rubber body 103 connected between the outer tube 101 and the inner core 102. In addition, the outer tube 101 can be specifically press-fitted into the subframe, or connected to the subframe via a bracket. In addition, Figure 2 The up and down directions shown in the figure are the actual state diagram when the suspension assembly is installed on the vehicle. Therefore, when the connection point between the connecting part 203 and the connecting structure is broken, the connecting structure of the inner core 102 can support the connecting part 203 to prevent the power assembly from falling and being damaged.

[0046] like Figure 1 and 2 As shown in , as a preferred embodiment, the connection structure of this embodiment includes a connection block 104 that is convexly arranged along the axial direction of the inner core 102, and a limiting protrusion 1043 is provided on the connection block 104. The limiting protrusion 1043 can abut against the connecting portion 203 to limit the displacement of the connecting bracket 2 in the radial direction of the inner core 102. And, as a preferred embodiment, the limiting protrusion 1043 is two spaced apart along the radial direction of the inner core 102. Each limiting protrusion 1043 protrudes upward along the up-down direction of the whole vehicle, and in the application state of the suspension assembly, the two limiting protrusions 1043 are located in the front-to-back direction of the whole vehicle. Therefore, the displacement of the powertrain and the connecting bracket 2 in the front-to-back direction of the whole vehicle can be limited by the abutment of the limiting protrusion 1043 with the connecting portion 203, which can further prevent the powertrain from falling.

[0047] In this embodiment, as a preferred embodiment, Figure 2 As shown in , the connection structure has a first part 1041 and a second part 1042, one end of the first part 1041 is connected to the inner core 102, and the second part 1042 is arranged at the other end of the first part 1041. In addition, the length of the second part 1042 in the radial direction of the inner core 102 is greater than the length of the first part 1041, and the connection part 203 is connected to the second part 1042. At the same time, the above-mentioned limiting protrusion 1043 is also arranged on the second part 1042. Such a configuration can allow the connection part 203 to have a larger size, increase the contact area between the connection part 203 and the connection structure, and help improve the supporting effect of the connection structure on the connection part 203, which can better ensure that the power assembly does not fall.

[0048] In addition, to further improve the use effect, the cross section of the first part 1041 is smaller than the cross section of the inner core 102, and the inner core 102 is used to abut against the connecting part 203 to limit the displacement of the connecting bracket 2 along the axial direction of the inner core 102. In this way, the abutment between the inner core 102 and the connecting bracket can limit the displacement of the connecting bracket 2 along the axial direction of the inner core 102, thereby better ensuring that the connecting bracket 2 and the powertrain do not fall. Among them, as a preferred embodiment, Figure 2 As shown in FIG. 1 , the cross section of the inner core 102 of this embodiment is rhombus-shaped, and the cross section of the first portion 1041 is rectangular and is located in the middle of the inner core 102. Obviously, the cross sections of the inner core 102 and the first portion 1041 are not limited to Figure 2 The shapes shown in the figure can be adjusted accordingly according to design requirements.

[0049] In addition, in order to prevent the second portion 1042 from being too long and colliding with the outer tube 101 to produce abnormal noise, as a further embodiment, Figure 1 and Figure 2 As shown in , one end of the outer tube 101 is provided with a flange 1011, and the rubber body 103 has a limiting portion 1031 located on the flange 1011. Moreover, the limiting portion 1031 is used to abut against the connecting structure to limit the displacement of the connecting structure along the axial direction of the inner core 102.

[0050] In addition, as a preferred embodiment, a connecting portion is provided on the connecting block 104, the connecting portion is located between the two limiting protrusions 1043, and the connecting block 104 is detachably connected to the connecting portion 203 through the connecting portion. This design facilitates the disassembly, maintenance and replacement of the connecting bracket 2. In order to facilitate processing and manufacturing, the connecting portion of this embodiment includes a plurality of first connecting holes M or connecting columns with threads that are spaced apart along the arrangement direction of the two limiting protrusions 1043.

[0051] Moreover, by arranging multiple first connecting holes M or connecting columns with threads at intervals along the arrangement direction of the two limiting protrusions 1043, the advantage of the larger length of the second part 1042 can be fully utilized. At the same time, compared with the axial spacing along the inner core 102, the space occupied by the connecting structure in the left and right directions of the entire vehicle can be reduced, the cantilever length can be reduced, and the connecting structure can provide better supporting effect on the connecting bracket 2.

[0052] And, combined with Figure 1 and Figure 2 As shown in , the connection portion of this embodiment specifically includes two first connection holes M provided on the second portion 1042. Figure 3 As shown in , a through hole N is provided on the connection part 203 corresponding to the two first connection holes M, and the connection part 203 is connected by a bolt 3 passing through the through hole N and the first connection hole M. Among them, the first connection hole M can be set as a threaded hole or a smooth hole according to design requirements.

[0053] It should be noted that, in addition to including two first connection holes M, the connection portion may also be provided with only one, or more. Moreover, in addition to using the first connection holes M, the connection portion may also use a connection column with a thread. In addition, in addition to using the connection portion and the connection part 203 to be detachably connected, the connection structure may also be connected by welding.

[0054] In this embodiment, in order to facilitate the connection between the connection bracket 2 and the powertrain, as a preferred embodiment, a second connection hole P is provided on the connection bracket 2, and the connection bracket 2 is connected to the powertrain through a fastener inserted in the second connection hole P. In addition, the opening direction of the second connection hole P is the same as the connection direction between the connection portion 203 and the connection structure. In other words, the opening direction of the second connection hole P is set along the up-down direction of the vehicle.

[0055] Among them, Figure 3 As shown in , as a preferred embodiment, the connection bracket 2 of this embodiment has a main arm 201, and a support arm 202 spaced apart from the main arm 201, the support arm 202 is connected to one end of the main arm 201, and the connection portion 203 is provided at the end where the main arm 201 is connected to the support arm 202. With this design, the connection bracket 2 is U-shaped as a whole, and the connection portion 203 is specifically a block structure protruding outwardly toward one side of the main arm 201.

[0056] In this embodiment, by arranging the connecting portion 203 at one end where the main arm 201 and the support arm 202 are connected, the structural strength of the position is relatively high, and the setting strength of the connecting portion 203 can be improved, which is conducive to improving the supporting effect of the inner core 102 on the connecting bracket 2. In addition, in order to improve the connection firmness between the connecting bracket 2 and the power assembly, a plurality of second connecting holes P are arranged at intervals along the length direction of the main arm 201 and the support arm 202. The above-mentioned fasteners can be specifically bolts in the prior art. In addition, in order to further improve the use effect, the connecting bracket 2 can be cast as a whole to have a higher structural strength.

[0057] In addition, it should be noted that the structure of the connecting bracket 2 is not limited to Figure 3 The shape shown in the figure can be adjusted according to the design requirements. Moreover, the opening direction and number of the second connection holes P are not limited to Figure 3 As shown in , it can also be adjusted accordingly depending on the specific situation.

[0058] The suspension assembly of this embodiment adopts the above structure, and when the bolt 3 connected between the connecting portion 203 and the connecting structure is loosened or broken, the power assembly will tend to fall downward with the connecting bracket 2. Since the connecting block 104 that contacts the connecting structure and the connecting bracket 2 is a U-shaped structure with a low middle and high sides, during the falling process, the connecting bracket 2 is always supported by the connecting block 104 due to the limiting effect of the inner core 102 and the limiting protrusion 1043, thereby preventing the power assembly from continuing to fall and ensuring the safety of the vehicle.

[0059] In normal assembly, the power assembly and the connecting part 203 are placed on the connecting bracket 2 from top to bottom, and the bolts 3 are tightened from top to bottom to connect the two, so the connecting block 104 does not affect the normal assembly. In addition, the connecting bracket 2 and the connecting block 104 of this embodiment also have the characteristics of low cost, easy installation and high reliability.

[0060] In addition, the present embodiment also relates to a vehicle, on which the suspension assembly as described above is provided.

[0061] The vehicle of this embodiment has the same beneficial effects as the above-mentioned suspension assembly relative to the prior art, which will not be described in detail here.

[0062] 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.
