[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Off-road vehicles generally use a double wishbone suspension system. The width between the suspension support and the wheel must be reserved and cannot be used to house components of various systems, including pipelines. On a chassis with a width limit, the chassis' own subsystems occupy too much space, which is not conducive to the installation of superstructure equipment and also not conducive to the reasonable control of the chassis center of gravity height.

[0033] Chinese Patent No. CN202022196078.9 discloses a trailing arm suspension drive assembly, belonging to the field of automotive parts technology. Its technical solution includes a suspension body, which integrates a hub motor, brake calipers, hydraulic springs, and a semi-circular trailing arm mounting component, achieving high precision, simplified assembly process, and minimal space occupation. The hub motor has a longitudinal limiting boss on its top, and a longitudinal movement limiter above the boss. The semi-circular trailing arm mounting component has a swing opening at the end facing the hub motor. The side of the suspension body has an outwardly protruding lateral limiting block. The suspension body swings at the swing opening, with the upper limit of the swing restricted by the longitudinal limiting boss and the longitudinal movement limiter. The opening angle of the swing opening is 180 degrees, enabling a large tire travel distance, adapting to complex road conditions. The structure is simple, with fewer parts, greatly simplifying the assembly process, resulting in low cost and minimal space occupation. The combined application of trailing arm suspension and hub motors emphasizes the trailing arm suspension's ability to achieve large wheel sway, boasting a simple structure, streamlined assembly process, low cost, and small footprint. However, it lacks a reasonable optimization design for the trailing arm suspension's installation structure and space, as well as the necessary conditions to ensure the suspension's functionality.

[0034] To address the aforementioned problems, this application provides a frame that combines... Figure 1 and Figure 2 ,include:

[0035] The frame crossbeam 1 is installed laterally on the inner side of the frame longitudinal beams 3 on both sides.

[0036] Suspension supports 2 are provided on the outer side of the longitudinal beams 3 on both sides of the vehicle frame, and the suspension bracket 2 on one side passes through the longitudinal beam 3 of the vehicle frame and is connected to one end of the cross beam 1 of the vehicle frame.

[0037] Two longitudinal cantilever arms 5 are symmetrically arranged on the front and rear sides of a suspension support 2. One end of the longitudinal cantilever arm 5 on one side is hinged to the suspension support 2, so that the longitudinal cantilever arm 5 can rotate in the vertical plane. The other end of the longitudinal cantilever arm 5 is connected to the wheel 6.

[0038] Two elastic elements 7 are located on the front and rear sides of the suspension support 2, respectively. One elastic element 7 is positioned directly above the corresponding longitudinal cantilever 5. One end of the elastic element 7 is hinged to the suspension support 2, and the other end is hinged to the corresponding longitudinal cantilever 5. The elastic element 7 can be a hydraulic cylinder. The elastic element 7 mainly functions to reset the longitudinal cantilever 5 and dampen the shock of the wheel 6.

[0039] The vehicle frame provided in this application includes a suspension support 2, a longitudinal cantilever 5, and an elastic element 7. Two longitudinal cantilever 5 are symmetrically arranged on the front and rear sides of a suspension support 2. One end of the longitudinal cantilever 5 on one side is hinged to the suspension support 2, so that the longitudinal cantilever 5 can rotate in the vertical plane. The other end of the longitudinal cantilever 5 is connected to the wheel 6. Two elastic elements 7 are located on the front and rear sides of the suspension support 2. One elastic element 7 is arranged directly above the longitudinal cantilever 5 on the corresponding side. One end of the elastic element 7 is hinged to the suspension support 2, and the other end is hinged to the longitudinal cantilever 5 on the corresponding side. The vehicle's frame allows the longitudinal suspension arms 5 on the front and rear wheels 6 to share a single suspension support 2, which saves space. At the same time, the symmetrical arrangement of the front and rear longitudinal suspension arms 5 on the suspension support 2 achieves a force balance effect, which is more conducive to the stability of the suspension support 2. Finally, the longitudinal suspension arms 5 swing longitudinally in the vertical plane, which saves the vehicle's lateral installation space compared to the typical lateral suspension arm arrangement.

[0040] See Figure 1 In one embodiment, the suspension support 2 is provided with cantilever lugs 22 on the front and rear sides respectively. The direction of the cantilever lugs 22 is parallel to the direction of the longitudinal beam 3 of the frame, so that the longitudinal cantilever 5 hinged to it can swing in the vertical plane.

[0041] See Figure 1 In one embodiment, shock absorber lugs 23 are provided on the front and rear sides of the suspension support 2, and the shock absorber lugs are located directly above the cantilever lugs 22. The direction of the cantilever lugs 22 is parallel to the direction of the longitudinal beam 3 of the vehicle frame, so that the elastic element 7 hinged to it can swing in the vertical plane.

[0042] One embodiment further includes a reinforcing member 4, which is disposed between the frame crossbeam 1 and the frame longitudinal beam 3. Multiple reinforcing bushings 41 are provided on the end face of the reinforcing member 4 facing the suspension support 2. The suspension support 2 is provided with bushing stop holes 210 corresponding to the reinforcing bushings 41, and the reinforcing bushings 41 are connected within the corresponding bushing stop holes 210. With the reinforcing member 4 and reinforcing bushings 41 provided, the reinforcing member 4 acts as a pad for the frame crossbeam, fixing the suspension support 2, reinforcing bushings 41, and frame crossbeam 1 together. The reinforcing bushings 41 are fitted into the bushing stop holes 210, reducing the horizontal shear stress between the suspension support 2 and the frame crossbeam 1, and enhancing the installation strength between the suspension support 2 and the frame crossbeam 1.

[0043] See Figure 3 In some embodiments, the two ends of the frame crossbeam 1 are respectively fixedly provided with a first connecting part 11, and the suspension support 2 is provided with a corresponding second connecting part 21. The second connecting part 21 is connected to the first connecting part 11. In this solution, the first connecting part 11 and the second connecting part 21 are both steel plates with connecting holes and are fixed by bolts.

[0044] See Figure 3 In one embodiment, the two first connecting parts 11 are symmetrically inclined at both ends of the frame crossbeam 1, and the first connecting part 11 on one side is inclined from top to bottom in the vertical direction towards the frame crossbeam 1. Thus, the connection between the first connecting part 11 and the second connecting part 21 is also inclined. When the suspension support 2 and the frame crossbeam 1 tend to move relative to each other vertically, the inclined connection will generate a longitudinal force to counteract this tendency. Compared with the horizontal connection, it is more conducive to maintaining the stability of the suspension support 2 and the frame crossbeam 1.

[0045] See Figure 4 In one embodiment, in order to improve the fixing effect of the second connecting part 21 on the suspension support 2, a reinforcing rib plate 212 is provided between the second connecting part 21 and the suspension support 2.

[0046] See Figure 4 In one embodiment, a plurality of connecting holes 211 are provided on the second connecting part 21. The plurality of connecting holes 211 are arranged from top to bottom on both sides of the second connecting part 21 and are fixedly connected to the frame crossbeam 1 through the connecting holes 211.

[0047] See Figure 4 In one embodiment, a plurality of connecting holes 211 are arranged from top to bottom on both sides of the second connecting part 21, with adjacent connecting holes 211 on one side being staggered in a horizontal direction. In this way, during the connection process, the connection force on each connecting hole 211 is distributed at multiple points, and the connection force area between the second connecting part 21 and the frame crossbeam 1 is larger, resulting in a more stable connection.

[0048] See Figure 3 In some embodiments, in order to make the end of the frame beam 1 and the first connecting part 11 more tightly fixed, and to make the force-bearing area of ​​the end of the frame beam 1 and the first connecting part 11 larger, the two ends of the frame beam 1 are provided with upward protruding bosses 12, and the bosses 12 and the end of the first connecting part 11 are connected together to 4 to increase the connection area.

[0049] See Figure 3 In some embodiments, the first connecting portion 11 is welded to the end face of the boss 12.

[0050] This embodiment also provides a vehicle including the aforementioned frame. The vehicle with the aforementioned frame saves lateral installation space and reduces the horizontal shear stress between the suspension support 2 and the frame crossbeam 1, thereby enhancing the installation strength between the suspension support 2 and the frame crossbeam 1 and having good practicality.
