Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and specifically relates to a powertrain suspension structure and a vehicle. Background Art

[0002] With the progress of the times, the driving safety and comfort of automobiles have gradually become the main concerns of people. Therefore, the suspension structure of the powertrain must have the functions of shock absorption, sound insulation and noise reduction. At the same time, it also needs to have the function of limiting the powertrain. While ensuring that the suspension can play a role in seismic isolation, it is also necessary to ensure that the powertrain moves within a controllable range to avoid collisions with surrounding parts due to excessive displacement of the powertrain. Therefore, the stiffness and structural form of the suspension will affect the stability of the powertrain and the comfort of the ride. Considering the comfort of the ride, the powertrain suspension needs to be as soft as possible, and the rubber hardness needs to be lower. Considering the stability of the powertrain, the suspension stiffness needs to be higher, so the hardness of the rubber is increased, which puts the suspension rubber in a contradiction.

[0003] The current suspension is a trapezoidal structure, and the internal rubber is directly vulcanized. The Z-direction (body height direction) stiffness of the suspension can only be improved by adjusting the hardness of the rubber. Compared with the higher Z-direction stiffness requirements of the trapezoidal suspension, it is difficult to meet them. And it also makes it difficult for the durability of the suspension structure to meet the standards.

[0004] For example, the patent document with publication number CN106476596A discloses a suspension of a powertrain, including an upper connecting plate, a lower connecting plate and a rubber block, wherein the rubber block is arranged between the upper and lower connecting plates, the two ends of the upper connecting plate are respectively formed with a first curling edge and a second curling edge, and the two ends of the lower connecting plate are respectively formed with a third curling edge and a fourth curling edge, forming a space for accommodating the rubber block; the suspension also includes an L-shaped fixing frame, the L-shaped fixing frame is provided with a mounting surface, the mounting surface is provided with a first fixing member for fixing to the engine support foot, and a set angle is formed between the mounting surface and the upper connecting plate. The suspension of the powertrain provided by the present invention is connected to the engine support foot through the first fixing member, and is connected to the upper connecting plate of the engine through the lower connecting plate. The technical solution disclosed in the patent document also cannot solve the technical problems described above. Utility Model Content

[0023] like Figures 1 to 3 As shown, the utility model provides a powertrain suspension structure, including a suspension bracket 6 and a suspension cushion, wherein the suspension bracket 6 is used to be connected to the vehicle body, and the suspension cushion is used to be connected to the powertrain, and the suspension cushion is located inside the suspension bracket 6. The suspension cushion includes a rubber main spring and a base 3 located below the rubber main spring, wherein the rubber main spring includes a main spring body 1 and a first connecting portion 2 connected to the main spring body 1, wherein the first connecting portion 2 is connected to the base 3, and a metal reinforcing member 4 is arranged inside the first connecting portion 2.

[0024] Specifically, if Figures 1 to 3As shown, two first connection parts 2 are provided, and the two first connection parts 2 are distributed in a V shape. The rubber main spring also includes a second connection part 5 connected to the first connection part 2 and the base 3. The second connection part 5 is located between the main spring body 1 and the base 3. The bottom surface of the second connection part 5 is connected to the base 3 as a whole. There is a certain distance between the second connection part 5 and the bottom surface of the main spring body 1, forming a buffer hole, which is conducive to vibration reduction. The upper ends of the two first connection parts 2 are connected to the main spring body 1, and the lower ends of the two first connection parts 2 are connected to the two ends of the second connection part 5. The second connection part 5 is located between the two first connection parts 2, and the distance between the upper ends of the two first connection parts 2 is greater than the distance between the lower ends of the two first connection parts 2. The first connection part 2 and the second connection part 5 are made of rubber material. The interior of the two first connection parts 2 is provided with a steel reinforcement 4. The reinforcement 4 is a rectangular sheet structure, and the first connection part 2 is formed on the reinforcement 4 by vulcanization.

[0025] The vulcanized steel sheet is located inside the first connecting part 2, and the trapezoidal suspension rubber is exposed to the outside and cannot be limited. A reinforcement member 4 is added inside so that during movement, the reinforcement member 4 directly acts on the rubber to increase the rubber stiffness, thereby improving durability.

[0026] like Figures 1 to 3 As shown, the main spring body 1 is a trapezoidal structure. An inner tube body made of metal is arranged inside the main spring body 1. The main spring body 1 is composed of the inner tube body and a rubber block vulcanized on the inner tube body. The inner tube 7 is a hollow structure. The base 3 includes an inner bracket and a rubber block vulcanized on the inner bracket. The inner bracket is made of cast aluminum.

Two first protrusions 8 are provided, and the two first protrusions 8 are respectively located on opposite sides of the main spring body 1. The height of the first protrusion 8 is less than the height of the second protrusion 9, and there is a certain distance between the first protrusion 8 and the inner wall surface of the suspension bracket 6. The first protrusion 8 and the second protrusion 9 are made of rubber, and the first protrusion 8 and the second protrusion 9 are integrally formed with the main spring body 1.

[0028] In the powertrain suspension structure of the above structure, the suspension rubber stiffness can be adjusted not only by the hardness of the rubber, but also by changing the thickness of the reinforcement 4, so the hardness of the rubber can be better selected, ensuring the stiffness while selecting a softer rubber to meet the durability requirements.

[0029] During manufacturing, the inner bracket, the reinforcement 4 and the inner tube body are vulcanized with rubber to form a suspension cushion, and the suspension cushion is pressed into the suspension bracket 6 to form a suspension assembly. The rubber part has no rigid restrictions, and after the reinforcement 4 is added, it will directly participate in the movement together with the rubber, thereby improving the collision effect and achieving the purpose of enhancing the rigidity.
