Description

[0001] The present application relates to the technical field of automobile suspension, and in particular to a rear suspension swing arm mounting assembly and a vehicle. Background Art

[0002] The suspension of a car is one of the indispensable parts of the car body. As a transmission device connecting the frame and the axle (or wheel), the suspension is also an important component to ensure the safety of the car. However, the weight of the suspension added to the body will increase the burden on the body. Therefore, the installation and reinforcement structure of the suspension is very important in the actual production process. At present, the traditional mounting points of the rear suspension swing arm of a car are set on the longitudinal beams on both sides of the frame. In order to achieve the required strength and stiffness requirements, a very thick reinforcement is often welded at the position where the suspension swing arm is connected to meet the use requirements of the body.

DETAILED DESCRIPTION

[0035] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0036] The following describes the rear suspension swing arm mounting assembly and the vehicle according to the embodiment of the present application with reference to the accompanying drawings. Figure 1 , Figure 2 , Figure 3 As shown, in view of the problem that the rear suspension swing arm in the related art mentioned in the background art needs to be assembled on the frame 2, and reinforcements (1 and 3 in the figure are reinforcements of different shapes) need to be added to the frame 2 to enhance the structural strength of the frame 2, the present application provides a rear suspension swing arm installation assembly and a vehicle, which can reduce the use of reinforcements, thereby simplifying the production process and reducing production costs. Thus, the technical problems of large consumables and long time consumption in the installation process of the rear suspension swing arm in the related art are solved.

[0037] Please also see Figures 4 to 8 , the present application provides some embodiments of a rear suspension swing arm mounting assembly and a vehicle.

[0038] like Figure 4 and Figure 5As shown, the rear suspension swing arm mounting assembly of the present application includes a left mounting plate 10, a right mounting plate 20 and a rear cross beam 30, wherein the right mounting plate 20 is arranged opposite to the left mounting plate 10; the rear cross beam 30 is arranged between the left mounting plate 10 and the right mounting plate 20; a first assembly portion 31 is provided at one end of the rear cross beam 30, and a second assembly portion 32 is provided at the other end; the first assembly portion 31 extends to the bottom of the left mounting plate 10 and is connected to the left mounting plate 10; the second assembly portion 32 extends to the bottom of the right mounting plate 20 and is connected to the right mounting plate 20; the area where the first assembly portion 31 is projected on the left mounting plate 10 is the first assembly area; the area where the second assembly portion 32 is projected on the right mounting plate 20 is the second assembly area; both the first assembly area and the second assembly area are provided with a bearing table 40 for assembling the rear suspension swing arm.

[0039] The rear suspension swing arm mounting assembly disclosed in this embodiment can be arranged on a vehicle body chassis for use, and the left mounting plate 10 and the right mounting plate 20 are relatively arranged on the frame chassis and can be fixed by welding or screwing. The rear cross beam 30 is arranged between the left mounting plate 10 and the right mounting plate 20 along the width direction of the vehicle body, so as to play a role in transversely strengthening the structural strength of the vehicle body.

[0040] Specifically, the first assembly part 31 and the second assembly part 32 are respectively provided at both ends of the rear cross beam 30, and are stacked with the left mounting plate 10 and the right mounting plate 20. The rear cross beam 30 is connected with the left mounting plate 10 and the right mounting plate 20 in a stacked manner to form a first assembly area and a second assembly area. By assembling the rear suspension swing arm in the first assembly area and the second assembly area, it is not necessary to set a reinforcement on the longitudinal beam of the automobile, thereby reducing the process of body manufacturing and improving processing efficiency.

[0041] Specifically, in the first assembly area, the rear cross beam 30 and the left mounting plate 10 are connected as a whole, and in the second assembly area, the rear cross beam 30 and the right mounting plate 20 are connected as a whole to form a two-layer plate structure; obviously, in the first assembly area and the second assembly area, the thickness of the rear suspension swing arm mounting assembly is large and the structure is stable, so a load-bearing table 40 can be set for assembling the rear suspension swing arm, which can play a role of stable support and does not need to add local reinforcement parts. Therefore, it is beneficial to reduce production materials, simplify the manufacturing process, reduce production costs and work difficulty, and help achieve the purpose of reducing costs and weight.

[0042] In one implementation of the embodiment of the present application, Figure 6 and Figure 7As shown, the left mounting plate 10 includes a first connection body 11 disposed in the first assembly area, and a first flanging 12 and a second flanging 13 formed by sheet metal on both sides of the first connection body 11; a first assembly slot is formed on one side of the first connection body 11 facing the first assembly portion 31; the first flanging 12 and the second flanging 13 are oppositely disposed on both sides of the first assembly slot; the first assembly portion 31 includes a first connection segment 311 protruding toward the first assembly area, and a third flanging 312 and a fourth flanging 313 formed by sheet metal on both sides of the first connection segment 311; wherein, the first connection segment 311 is inserted into the first connection body 11, the third flanging 312 is attached to the first flanging 12, and the fourth flanging 313 is attached to the second flanging 13.

[0043] Specifically, the first connection body 11, the first flanging 12 and the second flanging 13 disclosed in this embodiment can be integrally formed, and the overall cross-sectional shape is a "Ji" shape. Therefore, at least four surfaces, namely the first flanging 12, the second flanging 13, and the side wall and the bottom wall in the first assembly slot, can be respectively in contact with the third flanging 312, the fourth flanging 313 and the first connection segment 311, so as to increase the contact area and improve the connection stability. Compared with the traditional frame rear beam structure using a "one" shaped member or a "Kuang" shaped member, the "Ji" shaped member in this embodiment has higher structural strength, is not easily deformed, and can be accurately aligned and matched during the docking process, is not easily offset, and has a large contact area at the docking position. Therefore, after being connected into one body, the connection between the left mounting plate 10 and the rear cross beam 30 is firm, not easily loosened or shaken, which is beneficial to long-term and stable use.

[0044] In an implementation manner of the embodiment of the present application, as Figure 7 shown, the width of the first connection body 11 is smaller than the width of the first assembly slot; one side of the first connection body 11 is in contact with the side wall of the first assembly slot, and a first assembly gap 50 is formed between the other side and the side wall of the first assembly slot.

[0045] Specifically, in the actual manufacturing process, it is inevitable that there are dimensional errors in the processing of irregularly shaped plates. Therefore, a gap is left between the left mounting plate 10 and the rear cross beam 30 to absorb manufacturing errors. During the process of inserting the left mounting plate 10 into the first assembly slot, since the width of the first connection body 11 is smaller than that of the first assembly slot, there is a gap between the first connection body 11 and at least one side wall of the first assembly slot, thereby reducing the frictional resistance during the assembly process and avoiding the situation that the assembly between the left mounting plate 10 and the rear cross beam 30 is difficult due to the influence of processing accuracy, improving the fault tolerance rate of production manufacturing and reducing the manufacturing difficulty.

[0046] Again, as Figure 7As shown, in one implementation of the embodiment of the present application, a first mating through hole is provided on the first connecting section 311; a second mating through hole is formed in the first assembly slot at a position opposite to the first mating through hole; the rear suspension swing arm mounting assembly includes a first assembly bolt 60, and the first assembly bolt 60 passes through the first mating through hole and the second mating through hole, and is used to fix the rear cross beam 30 to the left mounting plate 10.

[0047] Specifically, the rear cross beam 30 and the left mounting plate 10 are connected by the first assembly bolt 60, and the connection is firm and not easy to loosen, so that the first connection section 311 and the first connection body 11 are connected as a whole, and jointly support the rear suspension swing arm, thereby reducing the use of reinforcements and reducing production costs. In addition, this embodiment only exemplifies that the first connection section 311 and the left mounting plate 10 are connected by punching and installing the first assembly bolt 60, which is not an exhaustive example. In another implementation of this embodiment, the first connection section 311 can be welded to the left mounting plate 10, or the edge of the first connection section 311 and the left mounting plate 10 are welded while being connected using the first assembly bolt 60, so as to strengthen the connection strength between the first connection section 311 and the left mounting plate 10, so that the overall structure of the rear suspension swing arm mounting assembly is more stable and reliable.

[0048] In one implementation of the embodiment of the present application, a plurality of first mating vias are provided, and the plurality of first mating vias are arranged at intervals along the axial direction of the first connecting section 311; a plurality of second mating vias are provided, and the plurality of second mating vias are arranged at intervals along the axial direction of the first assembly slot.

[0049] Specifically, multiple first matching holes and multiple second matching holes are provided, and during assembly, the connection firmness between the left mounting plate 10 and the rear cross beam 30 can be increased through multi-point connection, the structural strength can be improved, and the rear suspension swing arm can have better support capacity. When the number of the first matching holes and the second matching holes is equal, multiple first assembly bolts 60 can be provided to achieve a one-to-one correspondence between each first matching hole and the second matching hole, and each pair of the first matching holes and the second matching holes is provided with a first assembly bolt 60, so as to achieve a multi-point connection between the left mounting plate 10 and the rear cross beam 30, improve the connection strength, and increase the structural stability. When the number of the first matching holes and the second matching holes is not equal, the first assembly bolt 60 can be provided to be assembled into some of the first matching holes, so as to achieve the effect of flexibly selecting the assembly position of the first assembly bolt 60, and increase the flexibility of assembling the left mounting plate 10 and the rear cross beam 30.

[0050] In one implementation of the embodiment of the present application, Figure 6 and Figure 8As shown, the right mounting plate 20 includes a second connecting body 21 arranged in the second assembly area and a fifth flange 22 and a sixth flange 23 formed by sheet metal on both sides of the second connecting body 21; a second assembly slot is formed on the side of the second connecting body 21 facing the second assembly part 32; the fifth flange 22 and the sixth flange 23 are relatively arranged on both sides of the second assembly slot; the second assembly part 32 includes a second connecting section 321 protruding toward the second assembly area, and a seventh flange 322 and an eighth flange 323 formed by sheet metal on both sides of the second connecting section 321; wherein, the second connecting section 321 is plugged into the second connecting body 21, and when the second connecting section 321 is inserted into the second assembly slot and fits with the right mounting plate 20, the fifth flange 22 fits with the seventh flange 322, and the sixth flange 23 fits with the eighth flange 323.

[0051] Specifically, in the present embodiment, the right mounting plate 20 and the second connecting section 321 are both configured to have a "J"-shaped structure in cross section, so that when the second connecting body 21 is docked with the second assembly slot, the fifth flange 22 fits with the seventh flange 322, and the sixth flange 23 fits with the eighth flange 323, thereby increasing the contact area between the right mounting plate 20 and the second assembly portion 32, making the second assembly portion 32 fit more closely with the right mounting plate 20 and improving the stability of the connection.

[0052] In one implementation of the embodiment of the present application, Figure 8 As shown, the width of the second connecting body 21 is smaller than the width of the second assembly slot; one side of the second connecting body 21 contacts the side wall of the second assembly slot, and a second assembly gap 70 is formed between the other side and the side wall of the second assembly slot.

[0053] Specifically, unlike the traditional connection method of completely fitting the two joints during assembly, in this embodiment, a gap is left between the right mounting plate 20 and the rear cross beam 30, and only one side of the second connecting body 21 is in contact with the side wall of the second assembly slot, while the other side forms a gap with the side wall of the second assembly slot, so as to absorb manufacturing errors and avoid the difficulty of assembly between the right mounting plate 20 and the rear cross beam 30 due to the influence of processing accuracy, thereby improving the fault tolerance of production and manufacturing and reducing the difficulty of manufacturing.

[0054] For example Figure 8As shown, in one implementation of the embodiment of the present application, a third mating through hole is provided on the second connecting section 321; a fourth mating through hole is formed in the second assembly slot at a position opposite to the third mating through hole; the rear suspension swing arm mounting assembly includes a second assembly bolt 80, and the second assembly bolt 80 passes through the third mating through hole and the fourth mating through hole, and is used to fix the rear cross beam 30 to the right mounting plate 20.

[0055] Specifically, the third matching hole and the fourth matching hole are provided, and the rear cross beam 30 and the right mounting plate 20 are connected by the second assembly bolt 80, so that the connection is firm and not easy to loosen, so that the second connecting section 321 and the second connecting body 21 are connected as a whole, and jointly support the rear suspension swing arm, thereby reducing the use of reinforcements and reducing production costs. It should be noted that the second connecting section 321 and the right mounting plate 20 disclosed in this embodiment can also be connected by welding.

[0057] Specifically, by providing a plurality of third matching holes and a plurality of fourth matching holes, the connection firmness between the right mounting plate 20 and the rear cross beam 30 can be increased through multi-point connection during assembly, thereby improving the structural strength and providing better support for the rear suspension swing arm. Of course, by providing a plurality of third matching holes and a plurality of fourth matching holes, the alignment position of the right mounting plate 20 and the rear cross beam 30 can be flexibly adjusted to achieve the effect of flexibly adjusting the installation position of the second assembly bolt 80, which is conducive to adjusting the relative position of the rear cross beam 30 and the right mounting plate 20 to meet production needs.

[0058] In one implementation of the embodiment of the present application, the left mounting plate 10 and the right mounting plate 20 are mirror structures, and the left mounting plate 10 is provided with a first connecting column, a first flange 12 and a second flange 13; the right mounting plate 20 is provided with a second connecting body 21, a fifth flange 22 and a sixth flange 23, and the first connecting section 311 and the second connecting section 321 are respectively provided on both sides of the rear cross beam 30. In this embodiment, the left mounting plate 10 and the right mounting plate 20 are mirror structures to each other, which simplifies the overall structure of the rear suspension swing arm mounting assembly and facilitates manufacturing; the two ends of the rear cross beam 30 can be formed by sheet metal into a first connecting section 311, a third flange 312, a fourth flange 313, and a second connecting section 321, a seventh flange 322 and an eighth flange 323, further simplifying the manufacturing process of parts and components, so as to improve production efficiency. In addition, the symmetrical structure makes the weight distribution of the rear suspension swing arm mounting assembly uniform, and when applied to the vehicle body, the balance of the vehicle body can be improved.
