[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] Example 1

[0045] This embodiment relates to a subframe assembly to solve the problem that the large variety and quantity of components in the subframe assembly in the prior art leads to high production costs.

[0046] In terms of overall structure, the subframe assembly of this embodiment includes a subframe 1 and a powertrain bracket 2 disposed on the subframe 1. The subframe 1 includes a first beam 101 arranged opposite to each other in a first direction, a second beam 102 arranged opposite to each other in a second direction, and a plurality of mounting parts for mounting the subframe 1 on the vehicle body.

[0047] The powertrain bracket 2 is provided with a first sleeve 204 and a second sleeve 205 for mounting the suspension bushing, and a third sleeve 206 for mounting the subframe bushing 5. The first sleeve 204 is arranged along a first direction, the second sleeve 205 is arranged along a second direction, and the third sleeve 206 is provided at least corresponding to a portion of the mounting part, and the third sleeve 206 is arranged along a third direction.

[0048] The subframe assembly described in this embodiment facilitates the installation of the powertrain on the powertrain bracket 2 by providing a first sleeve 204 and a second sleeve 205 respectively arranged along a first direction and a second direction on the powertrain bracket 2. Furthermore, by providing a subframe bushing 5 inside a third sleeve 206, and by providing the third sleeve 206 at least corresponding to a portion of the mounting portion, the subframe 1 and the powertrain bracket 2 can share at least a portion of the subframe bushing 5, thereby reducing the number of parts and thus reducing production costs.

[0049] Based on the above overview, an exemplary structure of the subframe assembly described in this embodiment is as follows: Figure 1 As shown in the diagram. In this embodiment, the subframe 1 is generally U-shaped, which is not only simple in structure and easy to arrange and implement, but also has good structural strength and stability. The powertrain bracket 2 is set at the top or bottom of the subframe 1 and is used to install the powertrain. In this embodiment, the first direction can be the front-rear direction or the left-right direction of the vehicle, and the second direction is set perpendicular to the first direction. The following description uses the example of the first direction being the front-rear direction of the vehicle, the second direction being the left-right direction of the vehicle, and the third direction being the height direction of the vehicle, with the powertrain bracket 2 set at the bottom of the subframe 1, to illustrate the structure of the subframe assembly.

[0050] As a preferred implementation method, such as Figure 1 As shown, each of the second beams 102 has a mounting portion at both ends, and the mounting portion includes a mounting cylinder 103 on the second beam 102. One end of the mounting cylinder 103 is open, and the other end has a mounting hole 1031. The third sleeve 206 is inserted into the corresponding mounting cylinder 103, and the subframe 1 is mounted on the vehicle body by fasteners passing through the mounting hole 1031 and the subframe bushing 5.

[0051] Here, the opening of the mounting sleeve 103 is set downwards, which facilitates the installation of the third sleeve 206 inside the mounting sleeve 103. The setting of the mounting hole 1031 facilitates the passage of fasteners. The tight fit between the third sleeve 206 and the mounting sleeve 103, as well as the use of fasteners, helps to ensure a firm and reliable connection between the subframe 1, the powertrain bracket 2 and the vehicle body.

[0052] Specifically, the specifications of the mounting cylinder 103 are compatible with those of the third sleeve 206, which facilitates the installation of the third sleeve 206 within the mounting cylinder 103. Furthermore, the bottom of the mounting cylinder 103 abuts against the top of the third sleeve 206, ensuring the third sleeve 206 is properly installed and limiting its upward movement during installation. The inner tube of the subframe bushing 5 within the third sleeve 206 is coaxially aligned with the mounting hole 1031. Fasteners such as bolts can pass through the mounting hole 1031 and the corresponding inner tube of the subframe bushing 5 in the vertical direction of the vehicle before connecting to the vehicle body.

[0053] In this embodiment, as Figure 2 As shown, the two ends of the second beam 102 are respectively inclined in the first direction away from the first beam 101 at the same end, so that the four mounting cylinders 103 are respectively located at the four corners of the subframe 1. The subframe 1 is installed on the vehicle body through the subframe bushing 5 in the second sleeve 205 inside the four mounting cylinders 103, which helps to ensure the installation stability of the subframe 1.

[0054] In a preferred embodiment, the powertrain bracket 2 described in this embodiment includes a first bracket unit disposed on a first beam 101, and two second bracket units disposed on two corresponding second beams 102. The first bracket unit is provided with a first sleeve 204, and each second bracket unit is provided with a second sleeve 205 and a third sleeve 206. Here, the powertrain bracket 2 is divided into a first bracket unit disposed on the first beam 101 and two second bracket units respectively disposed on the two second beams 102, so that the powertrain bracket 2 is distributed in a decentralized manner, which facilitates the more even distribution of the force borne by the powertrain bracket 2 to the different beam structures of the subframe 1.

[0055] like Figures 3 to 5 As shown, the first support unit includes two opposing sub-supports 201, and each second support unit includes a second support 202 that conforms to the corresponding second beam 102, and the second support 202 is integrally formed with the sub-supports 201 on each side. One end of each second support 202 is provided with a second sleeve 205, and the other end of each second support 202 is provided with a third sleeve 206.

[0056] The second bracket 202 and the side brackets 201 are integrally formed in an "L" shape, which improves the connection strength and assembly efficiency. The second sleeve 205 and the third sleeve 206 are respectively positioned at both ends of the second bracket 202, working in conjunction with the first bracket unit to enhance the stability of the subframe assembly. Furthermore, the two third sleeves 206 on the powertrain bracket 2 allow the subframe 1 and powertrain bracket 2 to share two subframe bushings 5, reducing the number of components.

[0057] In this embodiment, due to the arrangement of two sub-supports 201 and two second supports 202, the powertrain support 2 is generally n-shaped. The powertrain support 2 is connected to three beams in different directions of the subframe 1, which has good connection stability and helps to improve the strength of one of the first beams 101 and the two second beams 102 of the subframe 1.

[0058] Reference Figure 1 As shown in the diagram, in this embodiment, the two sub-supports 201 are symmetrically arranged on the bottom surface of the first beam 101 and conform to the shape of the first support 203. Of course, besides simply setting the two sub-supports 201 on... Figure 1 In addition to the first beam 101 positioned at the front, two first sub-supports 201 can also be positioned on the first beam 101 positioned at the rear. Furthermore, the sub-supports 201 being shaped to conform to the first beam 101 specifically means that the shape and specifications of the sub-supports 201 are the same as or approximately the same as the shape and specifications of the first beam 101.

[0059] As a feasible arrangement, the first sleeve 204 is located at one end of the sub-support 201 near the second beam 102, so that the two first sleeves 204 are located at both ends of the first beam 101, thereby connecting to the powertrain in the first direction and improving connection strength and reliability. For ease of distinction, the suspension support installed in the first sleeve 204 is called the first suspension bushing 3, and the suspension bushing installed in the second sleeve 205 is called the second suspension bushing 4.

[0060] The powertrain is connected to the powertrain bracket 2 via a connector that passes through the first suspension bushing 3 in a first direction, and is also connected to the powertrain bracket 2 via a connector that passes through the second suspension bushing 4 in a second direction. The cooperation of the two first suspension bushings 3 and the two second suspension bushings 4 here helps to improve the installation stability of the powertrain.

[0061] Continue to refer to Figure 1As shown, the second bracket 202 is conformally arranged to the second beam 102, meaning that their shapes and specifications are the same or approximately the same. This facilitates further improvement in the connection between the first bracket 203 and the second beam 102. A second sleeve 205 is provided at the end of the second beam 102 furthest from the first sleeve 204, allowing the first sleeve 204 and the second sleeve 205 to be positioned opposite each other, which improves the installation stability of the powertrain on the powertrain bracket 2. A third sleeve 206 is provided on the outer side of the end of the second beam 102 closest to the first sleeve 204, allowing the subframe 1 and the powertrain bracket 2 to share two subframe bushings 5.

[0062] In a preferred embodiment, the powertrain bracket 2 is attached to the subframe 1, and the subframe 1 has a clearance groove for accommodating the first sleeve 204 and the second sleeve 205. This attachment of the powertrain bracket 2 to the subframe 1 not only reduces the space occupied by the subframe assembly and optimizes the overall space layout of the vehicle's undercarriage, but also improves the connection between the powertrain bracket 2 and the subframe 1. The clearance groove facilitates a more compact installation of the powertrain bracket 2 and the subframe 1, further reducing space occupation and preventing interference during installation.

[0063] In specific implementation, the secondary support 201 is attached to the first beam 101, and the second support 202 is attached to the second beam 102. For ease of distinction, as follows... Figure 1 As shown, the clearance groove used to avoid the top of the first sleeve 204 is called the first clearance groove 104, and the clearance groove used to avoid the top of the second sleeve 205 is called the second clearance groove 105. In this embodiment, by placing the top of the first sleeve 204 in the corresponding first clearance groove 104, it is also beneficial to limit the displacement of the sub-support 201 along the second direction, which further improves the installation effect of the sub-support 201 on the first beam 101. In addition, by placing the top of the second sleeve 205 in the second clearance groove 105, it is beneficial to limit the displacement of the second support 202 along the first direction, which further ensures the installation effect of the second support 202 on the second beam 102.

[0064] Furthermore, a positioning part is provided between the subframe 1 and the powertrain bracket 2, which is used to position the powertrain bracket 2 on the subframe 1. This helps to ensure that the powertrain bracket 2 can be accurately installed on the subframe 1, reduces the time required to adjust the position of the powertrain bracket 2, and thus improves the installation efficiency of the powertrain bracket 2.

[0065] Specifically, such as Figures 5 to 8As shown, the positioning part includes an arc-shaped positioning groove 106 on the second beam 102 and an arc-shaped protrusion 2022 on the second bracket 202. The arc-shaped protrusion 2022 is inserted into the arc-shaped positioning groove 106 and positions the second bracket 202 in the first and second directions. Here, by inserting the arc-shaped protrusion 2022 into the arc-shaped positioning groove 106, the second bracket 202 is positioned in the first and second directions on the subframe 1, which helps to further improve the installation accuracy, especially the fitting accuracy of the holes, and also helps to reduce costs.

[0066] Meanwhile, compared to schemes that separately set other positioning structures in the first and second directions, the scheme of the arc-shaped protrusion 2022 and the arc-shaped positioning groove 106 working together also helps to simplify the structure of the positioning part, thereby helping to reduce production costs. In this embodiment, as shown... Figure 2 As shown, the mounting cylinder 103 is located at the top of the end of the second beam 102. The top surface of the mounting cylinder 103 is coplanar with the top surface of the second beam 102, and the bottom surface of the mounting cylinder 103 is higher than the bottom surface of the second beam 102. The second sleeve 205 protrudes towards the side closer to the first beam 101, which facilitates the insertion of the top of the second sleeve 205 into the mounting cylinder 103.

[0067] Combination Figures 5 to 8 As shown, in this embodiment, the arc-shaped positioning groove 106 is specifically disposed at the end of the second beam 102 and located on one side of the mounting cylinder 103. The arc-shaped positioning groove 106 is coaxially disposed with the mounting cylinder 103. The arc-shaped protrusion 2022 corresponds to the arc-shaped positioning groove 106 and is disposed on the outer peripheral wall of the third sleeve 206, and is coaxially disposed with the third sleeve 206. This makes the cross-sectional surface at the connection between the arc-shaped protrusion 2022 and the second beam 102 "L"-shaped in the first and second directions, and has a better positioning effect.

[0068] During the installation of the third sleeve 206 inside the mounting cylinder 103, as the third sleeve 206 is inserted into the second mounting cylinder 103, the arc-shaped protrusion 2022 can be inserted into the corresponding arc-shaped positioning groove 106. When the third sleeve 206 is installed in place inside the mounting cylinder 103, the top of the arc-shaped protrusion 2022 can abut against the bottom of the top of the arc-shaped positioning groove 106.

[0069] In the specific arrangement, each end of the second beam 102 is provided with an arc-shaped positioning groove 106, and each second bracket 202 is also provided with an arc-shaped protrusion 2022. This is conducive to maximizing the stability of the powertrain bracket 2 in the positioning state, so that neither the sub-bracket 201 nor the second bracket 202 can move relative to the subframe 1 in the first direction or the second direction, thereby improving installation efficiency and installation accuracy.

[0070] In this embodiment, the powertrain bracket 2 is preferably detachably connected to the subframe 1, which facilitates replacement or maintenance of both and helps reduce production costs. As a feasible connection method, such as... Figure 2 and Figure 3 As shown, both the bracket 201 and the second bracket 202 are provided with multiple first connecting holes 100 that are arranged through each other in a third direction. The first beam 101 and the second beam 102 are provided with multiple second connecting holes 200 that are arranged one-to-one with the first connecting holes 100. The second connecting holes 200 are threaded holes. Connecting components, such as bolts, pass through the first connecting holes 100 and are screwed into the corresponding second connecting holes 200. The structure of the first connecting holes 100, the second connecting holes 200, and the bolts is simple, easy to install and disassemble, and has low production costs.

[0071] To further enhance the connection strength between the second support 202 and the first beam 101 without a sub-support 201, such as Figure 4 As shown, an extension portion 2021 extending towards the end of the first beam 101 can also be provided at the free end of the second bracket 202. That is, the extension portion 2021 is located on the side of the second sleeve 205 away from the first sleeve 204. The extension portion 2021 is also provided with the aforementioned first connecting hole 100, and a second connecting hole 200 corresponding to the first connecting hole 100 is provided on the first beam 101. The connection between the extension portion 2021 and the first beam 101 is beneficial to further improve the connection strength and reliability between the powertrain bracket 2 and the subframe 1, and to facilitate the transmission of guiding force to the corresponding first beam 101.

[0072] In this embodiment, the subframe 1 is preferably made of aluminum alloy through integral casting. This utilizes the significant advantages of aluminum alloy—low density and light weight—to reduce the weight of the subframe 1, thereby reducing the overall vehicle weight and improving fuel economy and vehicle handling performance. Simultaneously, the integral casting process ensures high structural integrity of the subframe 1, thus improving its machining accuracy. Furthermore, the subframe bracket 201 and the second bracket 202 are also preferably made of aluminum alloy through integral casting to further reduce the weight of the subframe assembly.

[0073] In addition, the first sleeve 204 is integrally formed with the sub-support 201, and the second sleeve 205 and the third sleeve 206 are integrally formed with the second support 202. This can further reduce the number of product components, improve the product integration level, reduce development costs, and also help increase the rigidity and strength of the first beam 101 and the two second beams 102 on the left and right sides of the subframe 1 corresponding to the first support 203.

[0074] The subframe assembly described in this embodiment optimizes the structure of the powertrain bracket 2, allowing the powertrain bracket 2 and the subframe 1 to share the subframe bushing 5. In specific implementation, the specifications of the suspension bushing and the subframe bushing 5 are preferably the same, which not only reduces the types of products developed and development costs, but also helps to improve the efficiency of product component platformization.

[0075] The subframe assembly of this embodiment integrates three sleeves 204, 205, and 206 in different directions on the powertrain bracket 2, eliminating the need for production assembly lines and large bushing pressing equipment for after-sales maintenance, thus reducing development and after-sales maintenance costs. The subframe assembly has a simple overall structure, is easy to implement, and has good adaptability and compatibility, which helps improve platform efficiency.

[0076] Example 2

[0077] This embodiment relates to a subframe assembly, which has a roughly the same structure as the subframe assembly in Embodiment 1, the only difference being the different structural forms of the first support unit and the second support unit.

[0078] like Figure 9 As shown, the first support unit of this embodiment includes two sub-supports 201 arranged opposite to each other. Each second support unit includes a second support 202 that is conformally arranged to the corresponding second beam 102, and the second support 202 is integrally formed with the sub-supports 201 on each side. Each second support 202 has a third sleeve 206 at both ends, and a second sleeve 205 is provided at the end of each second support 202 near the other first beam 101.

[0079] The second sleeve 205 is positioned at the other end of the second beam 102 relative to the first sleeve 204. The two second sleeves 205 and the two first sleeves 204 cooperate to facilitate the installation of the powertrain on the subframe 1. Furthermore, by connecting the powertrain to the powertrain bracket 2 in the first and second directions, the installation stability of the powertrain on the powertrain bracket 2 is also improved.

[0080] In this embodiment, the subframe assembly provides a third sleeve 206 at both ends of the second bracket 202, allowing the subframe 1 and the powertrain bracket 2 to share four subframe bushings 5. This maximizes the number of shared subframe bushings 5 ​​and helps reduce production costs.

[0081] Example 3

[0082] This embodiment relates to a subframe assembly, which has a roughly the same structure as the subframe assembly in Embodiment 1, the only difference being the different structural forms of the first support unit and the second support unit.

[0083] As a preferred implementation method, such as Figure 10 As shown, the first support unit includes a first support 203 that conforms to the first beam 101, and each second support unit includes a second support 202 that conforms to the corresponding second beam 102, and the second support 202 and the first support 203 are integrally formed. Each second support 202 has a second sleeve 205 at one end and a third sleeve 206 at the other end.

[0084] The first bracket 203 and the second bracket 202 are integrally formed, making the powertrain bracket 2 as a whole "n" shape, which not only helps to improve the connection strength between the two, but also improves the assembly efficiency. The second sleeve 205 and the third sleeve 206 are respectively set at both ends of the second bracket 202, which is easy to arrange and implement, and has a good effect.

[0085] The subframe assembly described in this embodiment is not only simple in structure and easy to implement, but also helps to reduce the number of parts and thus reduce production costs.

[0086] Example 3

[0087] This embodiment relates to a subframe assembly, which has a roughly the same structure as the subframe assembly in Embodiment 1, the only difference being the different structural forms of the first support unit and the second support unit.

[0088] like Figure 11 As shown, each first support unit includes a first support 203 that conforms to the first beam 101, and each second support unit includes a second support 202 that conforms to the corresponding second beam 102. The second support 202 and the first support 203 are integrally formed. Each second support 202 has a third sleeve 206 at both ends, and a second sleeve 205 at the end of each second support 202 closest to the other first beam 101. The integral formation of the first support 203 and the second support 202 not only improves the connection strength between them but also enhances assembly efficiency.

[0089] Specifically, the first support 203 extends along the second direction on the first beam 101, and the first support 203 and the two second supports 202 are integrally formed, so that the powertrain support 2 is in the shape of "n". This not only facilitates the layout and implementation, but also helps to improve the structural strength of the first beam 101 on which the first support 203 is provided and each of the second beams 102.

[0090] A third sleeve 206 is provided at both ends of the second bracket 202, and the second sleeve 205 is provided at one end close to the other first beam 101, which can share four subframe bushings 5, which is conducive to further increasing the number of subframe bushings 5 ​​shared by the subframe 1 and the powertrain bracket 2, thereby further reducing production costs.

[0091] In this embodiment, the second sleeve 205 is disposed at the other end of the second beam 102 relative to the first sleeve 204. The two second sleeves 205 and the two first sleeves 204 cooperate to facilitate the installation of the powertrain on the subframe 1. Furthermore, by connecting the powertrain to the powertrain bracket 2 in the first and second directions, the installation stability of the powertrain on the powertrain bracket 2 is also improved.

[0092] In this embodiment, the subframe assembly provides third sleeves 206 at both ends of the second bracket 202, allowing the subframe 1 and the powertrain bracket 2 to share four subframe bushings 5. This maximizes the number of shared subframe bushings 5 ​​and reduces production costs.
