Description

Technical Field

[0001] This application relates to the field of vehicle chassis, and more particularly to a vehicle and its suspension assembly. Background Technology

[0002] The suspension assembly is a key component that flexibly connects the chassis and powertrain. Its main functions are to support the weight of the powertrain, isolate vibrations and noise generated by the powertrain, and limit the movement of the powertrain relative to the chassis. Traditionally, the suspension mounts and powertrain brackets are connected by bolts. If the bolts break due to excessive load or loosen due to vehicle vibration, the connection between the powertrain bracket and the suspension mount fails, causing the powertrain to lose its support and detach from the chassis, thus posing a safety hazard. Utility Model Content

[0003] In view of this, the present application aims to provide a suspension assembly that can effectively prevent the powertrain from falling off and has good reliability.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0005] A suspension assembly includes a suspension bushing and a powertrain bracket connected to the suspension bushing along the axial direction of the suspension bushing.

[0006] The inner core of the suspension bushing is provided with a support portion. In the vertical direction of the vehicle, the support portion is located below the connection point between the suspension bushing and the powertrain bracket. When the connection structure between the powertrain bracket and the suspension bushing breaks, the powertrain bracket can be supported on the support portion.

[0007] Furthermore, the support portion includes a support protrusion that protrudes outward along the axial direction of the inner core; the powertrain bracket is provided with a support groove with an opening facing downward, and the support protrusion is inserted into the support groove.

[0008] Furthermore, the powertrain bracket is provided with a limiting part that blocks the opening of the support groove, the limiting part being used to prevent the support protrusion from dislodging from the support groove.

[0009] Furthermore, the limiting part includes a limiting block rotatably disposed on the powertrain bracket, and an elastic member disposed between the limiting block and the powertrain bracket; the limiting block can be pushed by the support protrusion to rotate into the support groove to avoid the support protrusion, and under the action of the elastic member, the limiting block can return to its original position.

[0010] Furthermore, the limiting part includes a limiting block rotatably disposed on the powertrain bracket; the limiting block is pushed by the supporting protrusion and can rotate into the supporting groove to avoid the supporting protrusion, and under the action of gravity, the limiting block is blocked at the opening of the supporting groove.

[0011] Furthermore, the limiting block includes a limiting body and a limiting protrusion provided on the limiting body; when the limiting block is positioned at the opening of the support groove, the limiting protrusion abuts against the powertrain bracket and restricts the limiting body from rotating outward from the support groove.

[0012] Furthermore, the powertrain bracket includes a bracket body and connecting arms disposed on two opposite sides of the bracket body; the bracket body is connected to the inner core, the support groove is disposed on the bracket body, and the connecting arms on both sides are provided with powertrain connection portions.

[0013] Furthermore, the inner core is provided with a through hole located above the support protrusion, and the bracket body is provided with a threaded hole corresponding to the through hole; the inner core is connected to the powertrain bracket by bolts passing through the through hole and the threaded hole.

[0014] Furthermore, the powertrain connection includes a connection hole on the connecting arm; the connection hole is located at the end of the connecting arm away from the bracket body and is arranged along the axial direction of the suspension bushing.

[0015] Compared with related technologies, this application has the following advantages:

[0016] (1) The suspension assembly described in this application, by providing a support part and placing it below the connection point between the powertrain bracket and the suspension bushing, can support the powertrain bracket in the vertical direction of the whole vehicle when the connection structure breaks, so as to prevent the powertrain bracket from falling down and thus prevent the powertrain connected to the powertrain bracket from falling off, thereby making the suspension assembly have good reliability and safety in use.

[0017] (2) Through the cooperative arrangement of the support groove and the support protrusion, during the assembly process of the powertrain bracket and the suspension bushing, the support protrusion can enter the support groove along the vertical direction of the vehicle, allowing the support groove to serve as a positioning structure. This helps ensure accurate positioning between the powertrain bracket and the suspension bushing, thereby improving assembly efficiency. Simultaneously, the cooperative arrangement of the support groove and the support protrusion constitutes a limiting constraint on the powertrain bracket, restricting its movement in the vertical direction perpendicular to the vehicle. This further prevents the powertrain bracket from detaching from the support protrusion, thereby further improving the reliability of the suspension assembly.

[0018] (3) By setting a limiting part, the limiting part can block the support protrusion at the opening of the support groove. When the connection structure breaks, it prevents the support protrusion from coming out of the opening of the support groove, improves the stability of the support protrusion in the support groove, thereby ensuring the stable connection between the powertrain bracket and the suspension bushing, and further improving the reliability of the suspension assembly.

[0019] (4) By setting a rotatable limiting block, the limiting block can be pushed and rotated by the supporting protrusion to avoid the supporting protrusion, allowing the supporting protrusion to enter the supporting groove through the slot. This avoids interference between the limiting part and the unassembled supporting protrusion, ensuring smooth assembly of the suspension bushing and the powertrain bracket. At the same time, after the supporting protrusion is assembled, the limiting block can be driven to reset by the elastic element, ensuring the limiting block's blocking effect on the supporting protrusion. This prevents the supporting protrusion from detaching from the supporting groove, thus better ensuring that the powertrain bracket will not fall off.

[0020] (5) By setting a limit block for rotational connection, the limit block can be pushed and rotated by the support protrusion to avoid the support protrusion, so that the support protrusion enters the support groove, and the support block can be automatically reset by gravity. Its structure is simple and reliable, which is convenient for assembly and improves the stability of the support protrusion in the support groove, thereby preventing the support protrusion from separating from the support groove, thus ensuring that the powertrain bracket will not fall off.

[0021] (6) By setting the limiting protrusion, the limiting protrusion can abut against the powertrain bracket to restrict the limiting block from rotating out of the slot, and prevent the limiting block from rotating due to the push of the supporting protrusion, so that the limiting block cannot block the supporting protrusion, thereby further improving the reliability of the limiting part and effectively preventing the supporting protrusion from falling out of the supporting slot.

[0022] (7) By setting up the bracket body and connecting arms, the two connecting arms extend outward from the bracket body and set the connection points of the powertrain on both sides of the bracket body. This can, to a certain extent, transmit the force from the powertrain to the bracket body evenly, improve the structural strength of the powertrain bracket, and thus enhance the connection effect between the suspension assembly and the powertrain.

[0023] (8) By using bolts as the connection structure, it has good structural strength and versatility. At the same time, the threaded end of the bolt can pass through the through hole and be screwed into the threaded hole on the powertrain bracket. Since the bolt is inserted into the through hole from the side of the suspension bushing, it can avoid interference between the bolt and the powertrain bracket during assembly, which facilitates assembly. Furthermore, the connection method between the bolt and the inner core and the powertrain bracket is simple, which can improve assembly efficiency and facilitate subsequent maintenance and replacement.

[0024] (9) The connecting holes on the connecting arm facilitate the connection of the connecting arm to the powertrain via bolts or other structures, ensuring the connection effect between the connecting part and the powertrain. At the same time, the connecting holes are arranged along the axial direction of the suspension bushing, which reduces the space occupied by the connecting arm.

[0025] This application also proposes a vehicle having a suspension assembly as described above.

[0026] The vehicle and / or the suspension assembly described in this application have the same technical effects as related technologies, and will not be described in detail here. Attached Figure Description

[0052] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0053] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0054] An embodiment of the first aspect of this application provides a mounting assembly for connecting a powertrain to a vehicle frame.

[0055] In related technologies, the traditional connection between the suspension mount and the powertrain bracket 2 is usually made using bolts 5. If the bolt 5 breaks due to excessive load or loosens due to vehicle vibration, the connection between the powertrain bracket 2 and the suspension mount will fail, causing the powertrain to detach from the vehicle frame, posing a safety hazard.

[0056] In view of this, in order to overcome the shortcomings of the related technology, the suspension assembly of this embodiment combines... Figures 1 to 5 As shown, the overall design includes a suspension bushing 1 and a powertrain bracket 2 connected to the suspension bushing 1 along the axial direction of the suspension bushing 1.

[0057] The inner core 101 of the suspension bushing 1 is provided with a support part. In the vertical direction of the whole vehicle, the support part is located below the connection point between the suspension bushing 1 and the powertrain bracket 2. When the connection structure between the powertrain bracket 2 and the suspension bushing 1 breaks, the powertrain bracket 2 can be supported on the support part.

[0058] Therefore, by setting up a support part and placing it below the connection point between the powertrain bracket 2 and the suspension bushing 1, the powertrain bracket 2 can be supported in the vertical direction of the entire vehicle when the connection structure breaks, so as to prevent the powertrain bracket 2 from falling downward and thus prevent the powertrain connected to the powertrain bracket 2 from falling off, thereby making the suspension assembly have good reliability and safety in use.

[0059] Based on the above overview, specifically, the powertrain in this embodiment refers to the power source installed on the vehicle, such as the drive motor and engine. Furthermore, as... Figure 12 , Figure 13 and Figure 14 As shown, similar to the overall structure of related technologies, the suspension bushing 1 in this embodiment includes a suspension housing 102 for connecting to the subframe, an elastic body 103 disposed in the suspension housing 102, and an inner core 101 passing through the elastic body 103. The elastic body 103 is made of rubber, which can weaken the vibration transmission between the inner core 101 and the suspension housing 102, and plays a role in isolating vibration in the suspension bushing 1. The inner core 101 has outwardly protruding prismatic structures at its upper and lower ends. The prismatic structure further restricts the relative rotation between the inner core 101 and the elastic body 103.

[0060] In some of the exemplary implementations, such as Figure 2 , Figure 4 and Figure 5 As shown, the support portion includes a support protrusion 1011 that protrudes outward along the axial direction of the inner core 101. The powertrain bracket 2 is provided with a support groove 3 with its opening facing downward, and the support protrusion 1011 is inserted into the support groove 3.

[0061] With the cooperation of the support groove 3 and the support protrusion 1011, during the assembly of the powertrain bracket 2 and the suspension bushing 1, the support protrusion 1011 can enter the support groove 3 along the vertical direction of the vehicle, so that the support groove 3 can serve as a positioning structure, which helps to ensure the accurate positioning between the powertrain bracket 2 and the suspension bushing 1, thereby improving assembly efficiency.

[0062] Meanwhile, the cooperative arrangement of the support groove 3 and the support protrusion 1011 constitutes a limiting constraint on the powertrain bracket 2, thereby restricting the movement of the powertrain bracket 2 in the direction perpendicular to the vertical direction of the vehicle. This can further prevent the powertrain bracket 2 from falling off the support protrusion 1011, thereby further improving the reliability of the mounting assembly.

[0063] In practical implementation, the inner wall of the support groove 3 is arc-shaped, and the side of the support protrusion 1011 that abuts against the support groove 3 conforms to the inner wall of the support groove 3. Through the arc-shaped inner wall, when the support protrusion 1011 abuts against the support groove 3, the support protrusion 1011 can guide the arc-shaped inner wall of the support groove 3, causing the support groove 3 to move. This, to a certain extent, ensures that the line connecting the connecting structure and the support protrusion 1011 coincides with the vertical direction of the vehicle, ensuring that the support protrusion 1011 supports the powertrain bracket 2 in the vertical direction of the vehicle and restricts the movement of the support protrusion 1011.

[0064] In some of the exemplary implementations, such as Figure 6 , Figure 7 As shown, the powertrain bracket 2 is provided with a limiting part that blocks the opening of the support groove 3. The limiting part is used to prevent the support protrusion 1011 from falling out of the support groove 3.

[0065] By providing a limiting part, the limiting part can block the support protrusion 1011 at the opening of the support groove 3. In the event of a breakage of the connecting structure, the limiting part can restrict the downward movement of the support protrusion 1011 at the opening, thereby preventing the support protrusion 1011 from coming out of the opening of the support groove 3, improving the stability of the support protrusion 1011 in the support groove 3, and thus ensuring a stable connection between the powertrain bracket 2 and the suspension bushing 1, further enhancing the reliability of the suspension assembly.

[0066] In some exemplary embodiments, the limiting part includes a limiting block 4 rotatably disposed on the powertrain bracket 2, and an elastic member disposed between the limiting block 4 and the powertrain bracket 2. The limiting block 4 is pushed by the support protrusion 1011 and can rotate into the support groove 3 to avoid the support protrusion 1011, and under the action of the elastic member, the limiting block 4 can return to its original position.

[0067] Understandably, during assembly, when the powertrain bracket 2 is installed from top to bottom, that is, when the support protrusion 1011 enters the groove from bottom to top relative to the support groove 3, the support protrusion 1011 can push against the limiting block 4, causing one end of the limiting block 4, which is blocked in the groove, to flip into the support groove 3. As the limiting block 4 rotates, the elastic element between the limiting block 4 and the powertrain bracket 2 is energized. Subsequently, after the powertrain bracket 2 is installed in place, the limiting block 4 is no longer pushed by the support protrusion 1011, and the energized elastic element causes the limiting block 4 to reset. The end of the limiting block 4 can then block the groove again and prevent the support protrusion 1011 from coming out of the support groove 3 from bottom to top.

[0068] Therefore, by setting a rotatable limiting block 4, the limiting block 4 can be pushed and rotated by the supporting protrusion 1011 to avoid the supporting protrusion 1011, allowing the supporting protrusion 1011 to enter the supporting groove 3 through the slot, thus avoiding interference between the limiting part and the supporting protrusion 1011, and ensuring the smooth assembly of the suspension bushing 1 and the powertrain bracket 2. At the same time, after the powertrain bracket 2 is assembled in place, the limiting block 4 can be driven to reset by the setting of the elastic element, ensuring the blocking effect of the limiting block 4 on the supporting protrusion 1011, thereby preventing the supporting protrusion 1011 from disengaging from the supporting groove 3, thus ensuring that the powertrain bracket 2 will not fall off.

[0069] In specific implementation, such as Figure 7 , Figure 9 and Figure 10 As shown, the aforementioned elastic element is a torsion spring 302, which is disposed between the limiting block 4 and the power assembly bracket 2. The power bracket has a rotating shaft 301 for rotatably connecting the limiting block 4. Both the power bracket and the limiting block 4 have grooves for receiving the two ends of the torsion spring 302, which is sleeved within the rotating shaft 301. When the limiting block 4 rotates, it pushes against the ends of the torsion spring 302 in its grooves, causing the torsion spring 302 to twist and store energy. Of course, other conventional elastic structures can also be used in this embodiment, as long as they can drive the limiting block 4 to rotate and reset.

[0070] Furthermore, the length of the limiting block 4 in the slot in this embodiment is limited. The limiting block 4 cannot completely block the slot; it can only reduce the width of the slot to prevent the support protrusion 1011 from coming out of the slot. By setting the length of the limiting block 4, while ensuring that the support protrusion 1011 is blocked, it can also prevent the support protrusion 1011 from getting stuck between the limiting block 4 and the inner wall of the support groove 3, so as to ensure that the support protrusion 1011 can be installed in place.

[0071] In some exemplary embodiments, as another structural form of the limiting part, the limiting part includes a limiting block 4 rotatably disposed on the powertrain bracket 2. The limiting block 4 is pushed by the supporting protrusion 1011 and can rotate into the supporting groove 3 to avoid the supporting protrusion 1011, and under the action of gravity, the limiting block 4 is blocked at the opening of the supporting groove 3.

[0072] By setting a rotatable limiting block 4, the limiting block 4 can be pushed and rotated by the supporting protrusion 1011 to avoid the supporting protrusion 1011, so that the supporting protrusion 1011 enters the supporting groove 3, and the supporting block can automatically reset by gravity. Its structure is simple and reliable. While facilitating assembly, it improves the stability of the supporting protrusion 1011 in the supporting groove 3, thereby preventing the supporting protrusion 1011 from separating from the supporting groove 3. This can better ensure that the powertrain bracket 2 will not fall off.

[0073] In practice, the length or weight of one end of the limiting block 4 located in the slot is greater than the length or weight of the other end of the limiting block 4, so as to ensure that the limiting block 4 on one side of the slot is heavier, so as to ensure that the limiting block 4 can be reset by gravity.

[0074] Based on this, in this embodiment, the limiting block 4 is configured as one, and the limiting block 4 is located on one side of the groove to block the support protrusion 1011 at the groove. In addition, as another embodiment, the limiting block 4 can be located not only on one side of the groove, but also on opposite sides of the groove. At the same time, one or more limiting blocks 4 can be provided on either side of the groove. By providing multiple limiting blocks 4, each limiting block can simultaneously block the support protrusion 1011, so as to further prevent the support protrusion 1011 from falling out of the support groove.

[0075] In some of the exemplary implementations, such as Figure 8 , Figure 11 As shown, the limiting block 4 includes a limiting body 401 and a limiting protrusion 402 provided on the limiting body 401. Specifically, when the limiting block 4 is positioned at the opening of the support groove 3, the limiting protrusion 402 abuts against the powertrain bracket 2 and restricts the limiting body 401 from rotating outward from the support groove 3.

[0076] By setting the limiting protrusion 402, the limiting protrusion 402 can abut against the powertrain bracket 2 to restrict the limiting block 4 from rotating out of the slot, and prevent the limiting block 4 from rotating due to the push of the supporting protrusion 1011, which would cause the limiting block 4 to be unable to block the supporting protrusion 1011, thereby further improving the reliability of the limiting part and effectively preventing the supporting protrusion 1011 from falling out of the supporting slot 3.

[0077] In specific implementation, the limiting protrusion 402 of this embodiment is provided on the side of the limiting body 401 facing the powertrain bracket 2, and protrudes towards the powertrain bracket 2 along the rotation axis of the limiting block 4, and can abut against the bottom side of the powertrain bracket 2.

[0078] In some of the exemplary implementations, such as Figure 2 As shown, the powertrain bracket 2 includes a bracket body 201 and connecting arms 202 disposed on two opposite sides of the bracket body 201. The bracket body 201 is connected to the inner core 101, the support groove 3 is disposed on the bracket body 201, and the connecting arms 202 on both sides are provided with powertrain connection parts.

[0079] With the support body 201 and connecting arms 202, the two connecting arms 202 extend outward from the support body 201, and the connection points of the powertrain are located on both sides of the support body 201, which can, to a certain extent, make the force from the powertrain evenly transmitted to the support body 201.

[0080] Meanwhile, when the two connecting arms 202 are connected to the powertrain, the powertrain and the powertrain bracket 2 form a ring-shaped support structure. The connection between the powertrain and the connecting arms 202 can limit the outward expansion of the ends of the two connecting arms 202, thereby preventing bending between the connecting arms 202 and the bracket body 201, thereby improving the structural strength of the powertrain bracket 2 and thus enhancing the connection effect between the suspension assembly and the powertrain.

[0081] In specific implementation, the support body 201 of this embodiment has an arched structure, and the supporting protrusion 1011 is located below the arched structure. The arched structure further improves the overall structural strength of the support body 201 and the powertrain support 2.

[0082] In some exemplary embodiments, the inner core 101 has a through hole 1012 located above the support protrusion 1011, and the bracket body 201 has a threaded hole 2011 corresponding to the connecting hole 203. The inner core 101 is connected to the powertrain bracket 2 by bolts 5 passing through the through hole 1012 and the threaded hole 2011.

[0083] Furthermore, it is understandable that if the threaded hole 2011 is located in the suspension bushing 1, the bolt 5 needs to first pass through the powertrain bracket 2 before connecting to the suspension bushing 1. However, since the powertrain bracket 2 is connected to the powertrain, and the space between the powertrain bracket 2 and the powertrain is small, the bolt 5 needs to be pre-installed on the powertrain bracket 2. At the same time, the powertrain bracket 2 needs to be inserted into the suspension bushing 1 along the axial direction of the bolt 5 to complete the assembly connection between the powertrain bracket 2 and the bushing, which restricts the installation direction between the powertrain bracket 2 and the suspension bushing 1.

[0084] Therefore, in the above implementation, the use of bolt 5 as the connection structure provides good structural strength and versatility.

[0085] Simultaneously, bolt 5 needs to pass through the through hole 1012 of the suspension bushing 1 so that the threaded end of bolt 5 can be screwed into the threaded hole 2011 on the powertrain bracket 2. Since bolt 5 is inserted into the through hole 1012 from one side of the suspension bushing 1, interference between bolt 5 and the powertrain bracket 2 during assembly is avoided, facilitating assembly. Furthermore, the connection method between bolt 5 and the inner core 101 and the powertrain bracket 2 is simple, improving assembly efficiency and facilitating subsequent maintenance and replacement.

[0086] In some exemplary embodiments, the powertrain connection includes a connection hole 203 provided on the connecting arm 202. The connection hole 203 is provided at the end of the connecting arm 202 away from the bracket body 201 and is arranged along the axial direction of the suspension bushing 1.

[0087] The connecting hole 203 on the connecting arm 202 allows the connecting arm 202 to be connected to the powertrain via bolts 5 or other structures, ensuring a good connection between the connecting part and the powertrain. At the same time, the connecting hole 203 is positioned along the axial direction of the suspension bushing 1, reducing the space occupied by the connecting arm 202.

[0088] It is worth noting that, regarding this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still... Figures 1 to 4 As shown, the suspension assembly of this embodiment includes a suspension bushing 1 and a powertrain bracket 2 connected to the suspension bushing 1 along the axial direction of the suspension bushing 1.

[0089] First, the suspension bushing 1 of this embodiment can be connected to the subframe. Furthermore, the suspension bushing 1 includes a suspension housing 102 for connecting to the subframe, an elastic body 103 disposed within the suspension housing 102, and an inner core 101 passing through the elastic body 103. The elastic body 103 can weaken the vibration transmission between the inner core 101 and the suspension housing 102, thus playing a role in isolating vibrations within the suspension bushing 1. The upper and lower ends of the inner core 101 have outwardly protruding prismatic structures; the arrangement of these prismatic structures further restricts the relative rotation between the inner core 101 and the elastic body 103.

[0090] In addition, a support portion is provided on the inner core 101 of the suspension bushing 1. In the vertical direction of the whole vehicle, the support portion is located below the connection point between the suspension bushing 1 and the powertrain bracket 2. When the connection structure between the powertrain bracket 2 and the suspension bushing 1 breaks, the powertrain bracket 2 can be supported on the support portion.

[0091] The support portion includes a support protrusion 1011 that protrudes outward along the axial direction of the inner core 101. The powertrain bracket 2 has a downward-facing support groove 3, into which the support protrusion 1011 is inserted. In the event of a breakage in the connecting structure, the support protrusion 1011 can abut against the support groove 3, thereby supporting the powertrain bracket 2 in the vertical direction of the vehicle, preventing the powertrain bracket 2 from falling downwards, and thus preventing the powertrain connected to the powertrain bracket 2 from detaching and causing a safety accident.

[0092] During the assembly of the powertrain bracket 2 and the suspension bushing 1, the support protrusion 1011 can enter the support groove 3 along the vertical direction of the vehicle, allowing the support groove 3 to serve as a positioning structure. This helps ensure accurate positioning between the powertrain bracket 2 and the suspension bushing 1, thereby improving assembly efficiency. The cooperative arrangement of the support groove 3 and the support protrusion 1011 constitutes a limiting constraint on the powertrain bracket 2, restricting its movement in the vertical direction perpendicular to the vehicle, and further preventing the powertrain bracket 2 from detaching from the support protrusion 1011.

[0093] Specifically, the inner wall of the support groove 3 is arc-shaped, and the side of the support protrusion 1011 that abuts against the support groove 3 conforms to the inner wall of the support groove 3. Through the arc-shaped inner wall, when the support protrusion 1011 abuts against the support groove 3, the support protrusion 1011 can support the arc-shaped inner wall of the groove 3, allowing the support groove 3 to move. This, to a certain extent, ensures that the line connecting the connecting structure and the support protrusion 1011 coincides with the vertical direction of the vehicle, ensuring that the support protrusion 1011 supports the powertrain bracket 2 in the vertical direction of the vehicle and restricting the movement of the support protrusion 1011.

[0094] In addition, the powertrain bracket 2 is provided with a limiting part that blocks the opening of the support groove 3. The limiting part is used to prevent the support protrusion 1011 from falling out of the support groove 3. In the event of a breakage of the connecting structure, the limiting part can restrict the support protrusion 1011 from moving downward at the opening, thereby preventing the support protrusion 1011 from falling out of the opening of the support groove 3 and improving the stability of the support protrusion 1011 in the support groove 3. The limiting part includes a limiting block 4 rotatably provided on the powertrain bracket 2. When the powertrain bracket 2 is installed from top to bottom, the limiting block 4 can be pushed by the support protrusion 1011 and rotated into the support groove 3 to avoid the support protrusion 1011.

[0095] Based on this, an elastic element can be provided between the limiting block 4 and the power assembly bracket 2. The elastic element is a torsion spring 302. The upper and lower parts of the torsion spring 302 are respectively embedded on the opposite sides of the limiting block 4 and the power assembly bracket 2. A rotating shaft 301 for rotatably connecting the limiting block 4 is formed on the power bracket. The power bracket and the limiting block 4 are respectively provided with grooves for receiving the two ends of the torsion spring 302. The torsion spring 302 is sleeved in the rotating shaft 301.

[0096] When the limiting block 4 rotates, it pushes against the end of the torsion spring 302 in its groove, causing the torsion spring 302 to twist and store energy. When the torsion spring 302 releases its energy, it can drive the limiting block 4 to reset. Alternatively, in this embodiment, the limiting block 4 can reset under its own gravity, causing it to be repositioned at the opening of the support groove 3.

[0097] Meanwhile, the length of the limiting block 4 within the slot is limited. The limiting block 4 cannot completely seal the slot; it can only reduce the width of the slot to prevent the support protrusion 1011 from coming out of the slot. By setting the length of the limiting block 4, while ensuring that the support protrusion 1011 is blocked, it can also prevent the support protrusion 1011 from getting stuck between the limiting block 4 and the inner wall of the support groove 3, thus ensuring that the support protrusion 1011 can be installed in place.

[0098] Furthermore, the limiting block 4 includes a limiting body 401 and a limiting protrusion 402 provided on the limiting body 401. When the limiting block 4 is positioned at the opening of the support groove 3, the limiting protrusion 402 abuts against the powertrain bracket 2 and restricts the limiting body 401 from rotating outward from the support groove 3. Specifically, the limiting protrusion 402 is provided on the side of the limiting body 401 facing the powertrain bracket 2, and protrudes towards the powertrain bracket 2 along the rotation axis of the limiting block 4, and can abut against the bottom side of the powertrain bracket 2. The limiting protrusion 402 can abut against the powertrain bracket 2 to restrict the limiting block 4 from rotating outward from the groove, preventing the limiting block 4 from rotating due to the pushing of the support protrusion 1011, which would cause the limiting block 4 to fail to block the support protrusion 1011, thereby further improving the reliability of the limiting part and effectively preventing the support protrusion 1011 from falling out of the support groove 3.

[0099] Furthermore, the powertrain bracket 2 includes a bracket body 201 and connecting arms 202 disposed on two opposite sides of the bracket body 201. When the two connecting arms 202 are connected to the powertrain, the powertrain and the powertrain bracket 2 form a ring-shaped support structure. The connection between the powertrain and the connecting arms 202 can limit the outward expansion of the ends of the two connecting arms 202, thereby preventing bending between the connecting arms 202 and the bracket body 201, thereby improving the structural strength of the powertrain bracket 2 and thus enhancing the connection effect between the suspension assembly and the powertrain.

[0100] The bracket body 201 is connected to the inner core 101, and the support groove 3 is provided on the bracket body 201. Powertrain connection portions are provided on the connecting arms 202 on both sides. The bracket body 201 has an arched structure, with the support protrusion 1011 located below the arched structure. The arched structure further improves the overall structural strength of the bracket body 201 and the powertrain bracket 2. The powertrain connection portion includes a connection hole 203 on the connecting arm 202. The connection hole 203 is located at the end of the connecting arm 202 away from the bracket body 201 and is arranged along the axial direction of the suspension bushing 1.

[0101] Finally, the inner core 101 has a through hole 1012 located above the support protrusion 1011, and the bracket body 201 has a threaded hole 2011 corresponding to the connecting hole 203. The inner core 101 is connected to the powertrain bracket 2 by bolts 5 passing through the connecting hole 203 and the threaded hole 2011. The bolts 5 need to pass through the connecting hole 203 of the suspension bushing 1 so that the threaded end of the bolts 5 can be screwed into the threaded hole 2011 on the powertrain bracket 2 for assembly.

[0102] The suspension assembly of this embodiment adopts the above design. By setting a support part and placing it below the connection point between the powertrain bracket 2 and the suspension bushing 1, it can support the powertrain bracket 2 in the vertical direction of the whole vehicle when the connection structure breaks, so as to prevent the powertrain bracket 2 from falling downward, thereby preventing the powertrain connected to the powertrain bracket 2 from falling off. As a result, this suspension assembly has good reliability and safety in use, and has good practicality.

[0103] An embodiment of the second aspect of this application provides a vehicle having the suspension assembly described above.

[0104] In this embodiment, the vehicle, through the aforementioned suspension assembly, ensures the reliability of the connection between the powertrain and the chassis, preventing the powertrain from detaching from the chassis and causing a safety accident, thereby improving the overall safety of the vehicle.

For those skilled in the art, this application can have various modifications and variations.
