Description

Technical Field

[0001] This disclosure relates to the field of vehicle powertrain technology, specifically to a suspension bracket, powertrain, and vehicle. Background Technology

[0002] Engine mounts primarily support the weight of the engine, therefore they must meet reliability, mechanical strength, and stiffness requirements to satisfy modal performance targets. Lighter mounts are more prone to deformation and breakage due to insufficient strength. To ensure modal stiffness, engine mounts need a certain weight. However, excessive weight not only wastes materials and increases the vehicle's load, leading to increased fuel consumption, but also reduces other modal performance characteristics, causing them to fail to meet NVH (Noise, Vibration, Harshness) performance requirements for components. Utility Model Content

[0003] The purpose of this disclosure is to provide a suspension bracket, powertrain, and vehicle that improves the modal performance of the bracket while reducing its weight.

[0004] To achieve the above objectives, this disclosure provides a suspension bracket, comprising:

[0005] A cushion mounting bracket for connecting to a suspended cushion;

[0006] Two connecting parts, wherein one end of the two connecting parts is connected to each other and attached to the cushion mounting base, and the other ends of the two connecting parts are disposed opposite to each other; and

[0007] An engine mounting bracket for connecting to an engine, wherein one end of each of the two connecting portions is respectively connected to both sides of the engine mounting bracket, and the connecting portions and the engine mounting bracket form a hollow structure.

[0008] Optionally, the engine mounting bracket includes:

[0009] Two mounting sections for connection to the engine, the two mounting sections being spaced apart and connected one-to-one with the two connecting parts; and

[0010] A reinforcing rib is connected between the two mounting sections.

[0011] Optionally, the mounting section includes:

[0012] First mounting ring;

[0013] A second mounting ring is spaced apart from the first mounting ring. Both the first and second mounting rings have first bolt holes for engaging with engine connection bolts.

[0014] A connecting rib is connected between the first mounting ring and the second mounting ring.

[0015] Optionally, the soft pad mounting base is disposed on the side close to the first mounting ring, and the two ends of the reinforcing rib are respectively connected to the two second mounting rings.

[0016] Optionally, the side of the connecting rib away from the soft pad mounting base has a recessed structure.

[0017] Optionally, the connecting part includes two side ribs, one end of the two side ribs is connected to each other, and the other end extends away from each other and is arranged opposite to each other. The connected end of the two side ribs is connected to the soft pad mounting base, and the opposite end of the two side ribs is connected to the first mounting ring and the connecting rib respectively.

[0018] Optionally, all the side ribs are arc-shaped ribs, and the two arc-shaped ribs protrude to the side away from each other.

[0019] Optionally, the ends of the two connecting parts that are connected to each other are integrally formed structures.

[0020] According to a second aspect of this disclosure, a powertrain is provided, the powertrain including a suspension pad, an engine, and the aforementioned suspension bracket.

[0021] According to a third aspect of this disclosure, a vehicle is provided, including the powertrain described above.

[0022] Through the above technical solution, with one end of the two connecting parts connected and the other end positioned opposite each other, not only can the two connecting parts form a symmetrical structure, ensuring uniform stress on the suspension bracket, but the space between the two connecting parts is also effectively hollowed out, reducing the weight of the suspension bracket. Furthermore, the hollowing out between the connecting parts and the engine mount also reduces the weight of the suspension bracket, thereby optimizing the overall structure of the suspension. This results in a 9% weight reduction compared to existing solutions, achieving structural lightweighting and reducing manufacturing costs. Simultaneously, on the basis of weight reduction, modal performance can be improved, with a 29.7% improvement in first-order modality and an 11.4% improvement in second-order modality, thus meeting vehicle NVH requirements.

[0023] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0031] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0032] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined in relation to the outline of the corresponding components. The terms "first," "second," etc., are used to distinguish different components and are not sequential or significant. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.

[0033] According to one embodiment of this disclosure, such as Figures 1 to 4As shown, a suspension bracket is provided, including a soft pad mounting base 1, two connecting portions 2, and an engine mounting base 3. The soft pad mounting base 1 is used to connect to a suspension soft pad 4. One end of each of the two connecting portions 2 is connected to the soft pad mounting base 1, and the other ends of the two connecting portions 2 can be arranged opposite each other. The engine mounting base 3 is used to connect to an engine, and the opposite ends of the two connecting portions 2 are respectively connected to both sides of the engine mounting base 3, with a hollow structure formed between the connecting portions 2 and the engine mounting base 3. Here, the interconnected ends of the two connecting portions 2 can be an integrally formed structure to improve the strength of the suspension bracket; this disclosure does not limit this aspect.

[0034] Through the above technical solution, with one end of the two connecting parts 2 connected and the other end positioned opposite each other, not only can the two connecting parts 2 form a symmetrical structure, ensuring uniform stress on the suspension bracket, but the space between the two connecting parts 2 is also effectively hollowed out, reducing the weight of the suspension bracket. Furthermore, the hollowing out between the connecting part 2 and the engine mount 3 also reduces the weight of the suspension bracket, thereby optimizing the overall structure of the suspension. This not only reduces the weight by 9% compared to existing solutions, achieving structural lightweighting and reducing manufacturing costs, but also improves modal performance on the basis of weight reduction, increasing the first-order modal performance by 29.7% and the second-order modal performance by 11.4%, thus meeting vehicle NVH requirements.

[0035] Furthermore, such as Figure 1 and Figure 4 As shown, the engine mounting bracket 3 may include two mounting sections 31 and a reinforcing rib 32. The mounting sections 31 are used to connect to the engine, and the two mounting sections 31 are spaced apart and connected to the two connecting parts 2 in a one-to-one correspondence. The reinforcing rib 32 connects the two mounting sections 31. In this way, the two parts of the engine mounting bracket 3 are connected only by the reinforcing rib 32. This allows for further hollowing out of the existing structure to further reduce the weight of the engine mounting bracket 3 while ensuring the modal performance of the suspension bracket, thus meeting the goals of lightweight suspension brackets and NVH performance requirements.

[0036] Furthermore, such as Figures 2 to 4As shown, the mounting section 31 may include a first mounting ring 311, a second mounting ring 312, and a connecting rib 313. The second mounting ring 312 may be spaced apart from the first mounting ring 311. Both the first mounting ring 311 and the second mounting ring 312 have first bolt holes 310 for engaging with the engine connecting bolt 5. The connecting rib 313 can connect between the first mounting ring 311 and the second mounting ring 312. The engine mounting base 3 is mounted to the engine at four points to improve the stability of the connection between the suspension bracket and the engine. Here, the installation direction of the suspension soft pad connecting bolt 6 may be perpendicular to the installation direction of the engine connecting bolt 5. The soft pad mounting base 1 may also have two second bolt holes 11 spaced apart for engaging with the suspension soft pad connecting bolt 6 to improve the connection stability with the suspension soft pad 4. This disclosure does not limit this. The distance between the two first mounting rings 311 and the distance between the two second mounting rings 312 may be equal to the distance between the first mounting ring 311 and the second mounting ring 312. This disclosure does not limit this. Alternatively, the side of the connecting rib 313 away from the soft pad mounting seat 1 can also be a recessed structure 3131. The recessed structure 3131 can effectively reduce the material used for the connecting rib 313, thereby further reducing the weight of the engine mounting seat 3.

[0037] Furthermore, such as Figure 3 As shown, the soft pad mounting base 1 can be positioned on the side close to the first mounting ring 311, and the two ends of the reinforcing rib 32 can be connected to two second mounting rings 312 respectively. The offset arrangement of the soft pad mounting base 1 and the reinforcing rib 32 can effectively improve the modal stiffness of the suspension bracket while reducing weight, making the connection between the engine and the suspension more secure.

[0038] According to one embodiment of this disclosure, such as Figures 1 to 3As shown, the connecting part 2 may include two side ribs 21. One end of the two side ribs 21 is connected to each other, and the other end extends away from each other and is positioned opposite each other. The connected end of the two side ribs 21 is connected to the soft pad mounting seat 1, and the opposite ends of the two side ribs 21 are respectively connected to the first mounting ring 311 and the connecting rib 313. In this way, the connecting part 2 can form a hollow structure with the engine mounting seat 3 to reduce the weight of the suspension bracket. The connecting part 2 can be formed into a U-shaped structure, that is, the connected end of the two side ribs 21 can be formed into a flat end and become the bottom of the U-shaped structure. The U-shaped structure is upside down on the engine mounting seat 3, its bottom is connected to the soft pad mounting seat 1, and its end is connected to the engine mounting seat 3, forming a hollow structure to reduce the weight of the suspension bracket. The connecting part 2 can also be formed into a V-shaped structure, that is, the connected end of the two side ribs 21 can be formed into a pointed end. The V-shaped structure is upside down on the engine mounting seat 3 and its end is connected to it, which can also form a hollow structure to reduce the weight of the suspension bracket. Of course, the connecting part 2 can also be a triangular ring structure, that is, the connecting part 2 itself is a hollow structure, and one side of its triangular ring is connected to the engine mounting base 3. This disclosure does not limit this. Here, the position of the side rib 21 connecting to the first mounting ring 311 can be located at the end of the first mounting ring 311 away from the connecting rib 313, so as to avoid the first bolt hole 310, so as to facilitate the connection of the engine connecting bolt 5.

[0039] Furthermore, such as Figures 1 to 3 As shown, the side ribs 21 can all be arc-shaped ribs, with each arc-shaped rib protruding away from the other. The arc-shaped ribs can reduce weight while increasing the overall strength of the suspension bracket, thus meeting the modal performance requirements of the suspension bracket.

[0040] Based on the above solutions, this disclosure also provides a powertrain, which includes a suspension pad 4, an engine and the aforementioned suspension bracket, and the powertrain has all the beneficial effects of the aforementioned suspension bracket, which will not be repeated here.

[0041] Based on the above solutions, this disclosure also provides a vehicle that includes the above powertrain and has all the beneficial effects of the above powertrain, which will not be repeated here.

However, the present disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0043] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0044] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
