Description

Technical Field

[0001] This utility model relates to the field of transport vehicle technology, specifically to a chassis assembly and a vehicle. Background Technology

[0002] Heavy-duty autonomous flatbed trucks are mainly used in unmanned port operations, where the operating environment is complex. The chassis is one of the main assemblies of the flatbed truck. Through the suspension system, it transmits all forces and torques between the chassis and the axle, mitigates the impact loads from uneven road surfaces, dampens vehicle vibrations caused by impact loads, and ensures that the vehicle has good handling stability and ride comfort.

[0003] In existing technologies, common bidirectional 8×4 transport vehicles are equipped with the same type of balanced suspension, such as a balance axle suspension or a balance beam suspension, both front and rear. The balance axle suspension uses a rigid balance axle running through the frame as its core, with the axles on both sides connected to the balance axle via connecting rods. The axle is fixed to the frame, resulting in even load distribution between axles and improved load-bearing stability, making it suitable for transport on paved or lightly unpaved roads. The balance beam suspension uses two sets of swingable balance beams as its core, with each beam connecting the front and rear wheels on the same side. The beams are hinged to the frame via hinge points, compensating for wheel height differences and handling uneven, potholed roads, reducing wheel slippage or wheel suspension.

[0004] However, the above-mentioned solution can only be fitted with one type of balance suspension on the vehicle frame. Different working conditions and operating scenarios have different requirements for vehicle load-bearing capacity and handling stability. If different balance suspension combinations are to be replaced, the vehicle frame needs to be redeveloped, which is detrimental to the control of development cycle and cost. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the chassis needs to be redeveloped for different working conditions and operating scenarios, thereby providing a chassis assembly.

[0006] To solve the above-mentioned technical problems, this utility model provides a vehicle frame assembly, including: longitudinal beams, crossbeams, and suspension mounting areas. The longitudinal beams are arranged along the length of the vehicle frame assembly, and the longitudinal beams include a first longitudinal beam and a second longitudinal beam arranged in parallel. Several crossbeams are arranged between the first longitudinal beam and the second longitudinal beam, with a first end connected to the first longitudinal beam and a second end connected to the second longitudinal beam. The suspension mounting area has one at each end of the first longitudinal beam and the second longitudinal beam. The web of the longitudinal beam in the suspension mounting area has several mounting holes, which form a first mounting area and a second mounting area. The first mounting area is used to install a balance beam suspension, and the second mounting area is used to install a balance shaft suspension.

[0007] In use, the first longitudinal beam, the second longitudinal beam, and several cross beams form a frame structure. Mounting holes in the suspension mounting areas at both ends of the longitudinal beams are used to assemble the balance suspension. The arrangement of these mounting holes forms the first and second mounting areas, allowing for the selection of balance beam suspension and / or balance axle suspension. Depending on the vehicle's different operating conditions and scenarios, and combining the characteristics of each type of balance suspension, flexible adaptation to different balance suspensions is achieved. The frame can be configured with balance axle suspension-balance axle suspension, balance axle suspension-balance beam suspension, balance beam suspension-balance beam suspension, etc., adapting to various transportation needs. Selecting balance suspension combinations for different scenarios eliminates the need for redesigning the frame, reducing R&D and manufacturing costs. The frame assembly provided by this invention solves the problem of needing to redevelop the frame for different operating conditions and scenarios. Optionally, the longitudinal beams are symmetrically arranged about the centerline of the vehicle assembly, the first and second longitudinal beams are symmetrically arranged about the perpendicular bisector of the centerline of the vehicle assembly, and the crossbeams and the suspension mounting area are symmetrically arranged about the perpendicular bisector of the centerline of the vehicle assembly.

[0012] Optionally, multiple outward-extending supports are provided along the length of the outer side of the longitudinal beam. These outward-extending supports are connected to the web of the longitudinal beam and the intermediate through-beam via fasteners. Each outward-extending support includes a second connecting plate, a supporting portion, and a limiting portion. The second connecting plate is disposed on the outer side of the longitudinal beam.

[0024] like Figure 1-8 As shown, this embodiment provides a specific implementation of a vehicle frame assembly, including: a longitudinal beam 1, a crossbeam 2, and a suspension mounting area 13. The longitudinal beam 1 is arranged along the length direction of the vehicle frame assembly, and the longitudinal beam 1 includes a first longitudinal beam 11 and a second longitudinal beam 12 arranged in parallel. Several crossbeams 2 are arranged between the first longitudinal beam 11 and the second longitudinal beam 12. The first end of the crossbeam 2 is connected to the first longitudinal beam 11, and the second end of the crossbeam 2 is connected to the second longitudinal beam 12. The suspension mounting area 13 is provided at both ends of the first longitudinal beam 11 and the second longitudinal beam 12. The web plate 16 of the longitudinal beam in the suspension mounting area 13 has several mounting holes, which form a first mounting area 131 and a second mounting area 132. The first mounting area 131 is used to install a balance beam suspension 7, and the second mounting area 132 is used to install a balance shaft suspension 6.

[0025] In use, the first longitudinal beam 11, the second longitudinal beam 12, and several crossbeams 2 form a frame structure. The mounting holes in the suspension mounting areas 13 at both ends of the longitudinal beams 1 are used to assemble the balance suspension. The arrangement of these mounting holes forms the first mounting area 131 and the second mounting area 132, allowing for the optional configuration of a balance beam suspension 7 and / or a balance shaft suspension 6. Based on different vehicle operating conditions and scenarios, and considering the characteristics of each suspension type, flexible adaptation of the two balance suspensions is achieved. The chassis can be configured with combinations such as balance shaft suspension 6-balance shaft suspension 6, balance shaft suspension 6-balance beam suspension 7, and balance beam suspension 7-balance beam suspension 7, adapting to various transportation needs. Different balance suspension combinations can be selected for different scenarios without requiring redesign of the chassis, reducing the R&D and manufacturing costs. The chassis assembly provided by this utility model solves the problem of needing to redevelop the chassis for different operating conditions and scenarios.

[0026] Specifically, the first mounting area 131 has multiple sets of mounting holes arranged in a matrix to accommodate the connection accessories between the balance beam suspension 7 and the longitudinal beam 1; the second mounting area 132 has several mounting holes for accommodating the balance shaft suspension 6; the first mounting area 131 and the second mounting area 132 have partially overlapping areas.

The main structure of the frame assembly is symmetrical front to back, which can take into account the symmetry of the vehicle's bidirectional driving arrangement. In addition, as an alternative implementation, the crossbeam 2 between the first longitudinal beam 11 and the second longitudinal beam 12 can be set as an asymmetrical structure according to the overall design requirements of the frame.

[0028] like Figure 3 As shown, in the frame assembly provided in this embodiment, the longitudinal beam 1 includes an inner beam 14 and an outer beam 15. The inner beam 14 and the outer beam 15 are configured as C-shaped beams. The outer surface of the inner beam 14 and the inner surface of the outer beam 15 are flush and fitted together. The upper and lower flanges of the inner beam 14 and the outer beam 15 are also flush and fitted together. The inner beam 14 and the outer beam 15 are riveted together. The longitudinal beam 1 is formed by riveting two C-shaped beams, which can enhance the strength of the longitudinal beam 1 and the torsional stiffness of the frame assembly as a whole. In addition, as an alternative embodiment, the longitudinal beam 1 can also be made of square steel or channel steel or other structures.

[0029] like Figure 1 As shown, in the frame assembly provided in this embodiment, the longitudinal beams 1 and crossbeams 2 are made of steel.

Alternatively, as an alternative implementation, the longitudinal beams 1 and crossbeams 2 can be made of aluminum alloy, titanium alloy, or other composite materials.

[0030] Specifically, the longitudinal beam 1 and the transverse beam 2 are made of BT700L high-strength steel, which, compared with the traditional B500L steel, has the characteristics of being lightweight, high-strength, having a large load-bearing capacity, and being able to withstand greater impacts, resulting in better lightweight performance.

[0031] like Figure 1As shown, in the frame assembly provided in this embodiment, the crossbeam 2 includes: a head-to-tail through crossbeam 21, a middle through crossbeam 22, and a middle support crossbeam 23. The head-to-tail through crossbeam 21 is disposed at both ends of the longitudinal beam 1, and connects the first longitudinal beam 11 and the second longitudinal beam 12. Several middle through crossbeams 22 are disposed along the length of the longitudinal beam 1, and connect the first longitudinal beam 11 and the second longitudinal beam 12. At least one middle support crossbeam 23 is disposed between two adjacent middle through crossbeams 22, and connects the first longitudinal beam 11 and the second longitudinal beam 12. The head-to-tail through crossbeam 21, the middle through crossbeam 22, and the middle support crossbeam 23 can connect the first longitudinal beam 11 and the second longitudinal beam 12, and improve the overall torsional stiffness of the frame assembly, ensuring stable connection. In addition, as an alternative implementation, the crossbeam 2 can also be equipped with one or a combination of two of the following: the head and tail through crossbeam 21, the middle through crossbeam 22, and the middle support crossbeam 23, depending on the overall structural design requirements of the vehicle frame.

The first connecting plates 222 at both ends of the through portion 221 enable the intermediate through beam 22 and the longitudinal beam 1 to form a stable connection through bolts, and the pipeline through hole 2211 on the through portion 221 facilitates the passage of internal pipelines and wiring harnesses of the frame. Alternatively, as an alternative embodiment, the pipeline through hole can be omitted, and the pipelines and wiring harnesses can pass through from below or above the intermediate through beam 22.

[0033] Specifically, such as Figure 4As shown, the first connecting plate 222 is provided with a plurality of mounting holes, through which the first connecting plate 222 is bolted to the longitudinal beam 1; the through part 221 includes: a through U-shaped plate 2212 and a through crossbeam connecting plate 2213, the through U-shaped plate 2212 has two oppositely arranged, the two ends of the through U-shaped plate 2212 are welded to the first connecting plate 222, and the through crossbeam connecting plate 2213 is welded to the first connecting plate 222 and the two opposite through U-shaped plates 2212; a plurality of reinforcing ribs 2214 are arranged circumferentially around the through part 221, and the reinforcing ribs 2214 are evenly arranged on both sides of the mounting holes of the first connecting plate 222.

[0034] like Figure 1 , Figure 5 As shown, in the frame assembly provided in this embodiment, a plurality of outward supports 3 are provided on the outer side of the longitudinal beam 1 along the length direction. The outward supports 3 are connected to the web plate 16 of the longitudinal beam and the intermediate through beam 22 through fasteners.

The supporting part 32 and the limiting part 33 cooperate to support the cargo. One end of the supporting part 32 is connected to the web of the longitudinal beam 16 through the second connecting plate 31. The extended bracket 3, the web of the longitudinal beam 16, and the intermediate through beam 22 are connected by bolts, which has good connection strength, so that the supporting part 32 has good load-bearing capacity, and at the same time, it can reduce the number of mounting holes on the web of the longitudinal beam. In addition, as an alternative embodiment, the extended bracket 3 can be omitted, and the limiting plate 333 is set on the outside of the longitudinal beam 1. The container or cargo is supported by the frame structure composed of the longitudinal beam 1 and the beam 2.

[0035] Specifically, such as Figure 5 As shown, the second connecting plate 31 is provided with a plurality of mounting holes, through which the first connecting plate 222 is bolted to the longitudinal beam 1.

The bearing plate is disposed at the top of the base plate 321, and the bearing surface is welded to the base plate 321 and the second connecting plate 31. The bearing plate is used to support containers or other goods. A reinforcing vertical plate 324 is also disposed between the bearing plate and the lower sealing plate 322. While ensuring the strength and stability of the support portion 32, a lightweight design has been implemented.

[0037] Specifically, such as Figure 5 As shown, the limiting part 33 includes: a side sealing plate 331, an outer sealing plate 332, and a limiting plate 333. The side sealing plate 331 has two oppositely arranged side sealing plates. The limiting plate 333 is located on the side of the side sealing plate 331 near the longitudinal beam 1. The limiting plate 333 is welded to the support part 32. The outer sealing plate 332 is located on the side of the side sealing plate 331 away from the longitudinal beam 1. The side sealing plate 331, the outer sealing plate 332, and the limiting plate 333 are welded to form a closed cavity, which improves the strength of the limiting part 33 of the extended bracket 3 and achieves a lightweight design.

[0038] Specifically, such as Figure 1 As shown, four intermediate through beams 22 are arranged along the length of the longitudinal beam 1, and four external supports 3 are arranged on each side of the longitudinal beam 1. The external supports 3 and the intermediate through beams 22 are arranged opposite each other, and bolts pass through the intermediate through beams 22, the web of the longitudinal beam, and the external supports 3. First external supports 34 and second external supports 35 are arranged sequentially from both ends of the longitudinal beam 1 toward the middle, and the suspension mounting area 13 is located in the middle area between the first external supports 34 and the second external supports 35.

[0039] Specifically, such as Figure 5 As shown, a lifting bracket 36 is welded to the side of the first extended bracket 34, so that four lifting brackets 36 are distributed in the front and rear of the vehicle frame, which facilitates the overall lifting of the vehicle frame.

[0040] like Figure 1As shown, in the frame assembly provided in this embodiment, connecting crossbeams 41 extending away from the longitudinal beams 11 and 12 are provided on the outer sides of both ends. A support leg 4 is provided at the end of the connecting crossbeam 41 away from the longitudinal beam 1. The support leg 4 supports the ground, and a support leg crossbeam 42 is provided between the two oppositely arranged support legs 4. The support legs 4 can meet the support requirements during vehicle assembly and can prevent damage to other vehicle systems caused by tire blowouts under extreme conditions. Alternatively, as an alternative implementation, the support legs 4 can be omitted, and the frame can be supported by a crane or other means during assembly.

[0041] like Figure 1 , Figure 6 , Figure 7 As shown, in the frame assembly provided in this embodiment, the suspension mounting area 13 is provided with a butterfly-shaped crossbeam 5 on the inner side of the longitudinal beam 1. The butterfly-shaped crossbeam 5 includes: an upper bending plate 51, a lower bending plate 52, and an intermediate connecting plate 53. The upper bending plate 51 and the lower bending plate 52 are provided at both ends of the intermediate connecting plate 53.

The lower surface of the lower bending plate 52 is connected to the lower surface of the intermediate connecting plate 53, and the side of the lower bending plate 52 is connected to the inner side of the longitudinal beam 1. The web of the intermediate connecting plate 53 is used to connect with the thrust rod of the balance shaft suspension 6. The butterfly-shaped crossbeam 5 is disposed inside the longitudinal beam 1 of the suspension mounting area 13, which can improve the overall strength of the frame. The main function of the butterfly-shaped crossbeam 5 is to work in conjunction with the balance shaft suspension 6. The butterfly-shaped crossbeam 7 can disperse the stress of the connection accessories between the balance shaft and the longitudinal beam 1, which is beneficial to improving the overall service life of the frame. In addition, as an alternative embodiment, the butterfly-shaped crossbeam 5 can be omitted, and it can be connected to the balance shaft of the balance shaft suspension 6 through the intermediate through crossbeam 22 or the intermediate support crossbeam 23.

[0042] Specifically, such as Figure 7 , Figure 8 As shown, the balance shaft suspension 6 has a V-shaped thrust rod and a leaf spring assembly with greater stiffness, which strengthens its ability to resist lateral forces and thus provides better stability on bumpy roads. However, the corresponding assembly weight and cost are also higher. The balance beam suspension 7 does not have an upper thrust rod and consists of two leaf springs connected in series with lower stiffness. It has a weaker ability to resist lateral forces and therefore has poorer stability on bumpy roads, but it has better load-bearing capacity and is correspondingly lighter and less expensive.

[0043] How to use: like Figure 1As shown, the vehicle frame assembly provided in this embodiment, when in use, consists of the first longitudinal beam 11, the second longitudinal beam 12, and several crossbeams forming a frame structure. The mounting holes in the suspension mounting areas 13 at both ends of the longitudinal beam 1 are used to assemble the balance suspension. The arrangement of the mounting holes forms the first mounting area 131 and the second mounting area 132. The balance beam suspension 7 and / or balance shaft suspension 6 can be selected. Depending on different working conditions and operating scenarios, and based on the vehicle's usage scenarios and working conditions, combined with the characteristics of the two suspensions, the chassis can be configured with combinations such as balance shaft suspension 6-balance shaft suspension 6, balance shaft suspension 6-balance beam suspension 7, and balance beam suspension 7-balance beam suspension 7.

[0044] In addition, this embodiment also provides a vehicle, including a cab and a frame assembly as described in any of the above solutions, wherein the cab is mounted on the longitudinal beam 1. By employing the frame assembly described in the above embodiments, the vehicle frame development cost can be reduced for different working conditions and scenarios.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
