Description

Technical Field

[0001] The utility model relates to a frame round tube beam assembly for a heavy truck and a vehicle, belonging to the technical field of vehicle frames. Background Art

[0002] The frame beams of heavy trucks are usually made of ordinary bent plates, which are assembled with multiple beam connecting plates to form a beam assembly. The large number of connecting plates in the beam assembly will result in a large frame weight, and the plate beam structure has poor torsional resistance. When the vehicle passes through a road with poor road conditions, the frame torsions will be large, causing the frame to deform, and even the beam connecting plate to break. Round tube beams are superior to ordinary plate beams in strength and torsional resistance, but the formed tube beams lack assembly holes, which is not convenient for the installation of vehicle components. Summary of the invention

[0003] In view of the problems existing in the above-mentioned prior art, the utility model provides a frame round tube beam assembly for a heavy truck and a vehicle, which solves the problems of easy breakage of the existing plate beams and lack of assembly holes in the round tube beams.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts a heavy-duty truck frame round tube beam assembly, comprising:

[0005] The pipe beam support comprises a pipe beam right support and a pipe beam left support which are identical in structure and symmetrically arranged;

[0007] U-shaped brackets, two of which are fixed on the circular tube beam;

[0008] The transmission shaft hanging bracket is installed on the two U-shaped brackets.

[0009] As an improvement, the thickness of the right support of the tubular beam is uneven.

[0010] As an improvement, the mounting hole on the right support of the tubular beam and the connection between the right support of the tubular beam and the circular tubular beam are provided with a thickened portion.

[0011] As an improvement, the right support of the tubular beam is provided with a limiting convex ring and a limiting protrusion for matching and connecting the circular tubular beam, and the diameter of the limiting convex ring is smaller than the diameter of the circular tubular beam.

[0012] As an improvement, the connection between the circular tube beam and the right support of the tube beam is fixed by circumferential welding.

[0013] As an improvement, a welding nut is provided on one side of the U-shaped bracket close to the round tube beam, and the transmission shaft hanging bracket is fixed to the U-shaped bracket by installing bolts.

[0014] As an improvement, the U-shaped bracket is welded on the round tube beam.

[0015] In addition, the utility model also provides a vehicle, on which the frame round tube beam assembly for a heavy truck is installed.

[0016] As an improvement, it includes a left longitudinal beam of the frame, a right longitudinal beam of the frame and a round tube beam assembly of the frame. The right support of the tube beam at one end of the round tube beam assembly is connected to the right longitudinal beam of the frame by connecting bolts and connecting nuts, and the left support of the tube beam at the other end is connected to the left longitudinal beam of the frame by connecting bolts and connecting nuts.

[0017] Compared with the prior art, the frame round tube beam assembly for heavy trucks of the utility model can effectively prevent the round tube beam from moving to both ends and avoid weld cracking through the left and right supports of the tube beam, thereby enhancing the strength of the frame round tube beam assembly; the round tube beam is adopted, and the strength and torsion resistance are better than those of ordinary plate beams; by installing a U-shaped bracket on the round tube beam, an assembly hole is provided, which is convenient for the installation of vehicle components.

[0024] In order to make the objectives, technical solutions and advantages of the present invention more clear, the technical solutions of the present application are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0025] In the description of the present invention, it should be understood that the terms "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the protection content of the present invention.

[0026] like Figure 1-Figure 4 As shown, a frame round tube beam assembly for a heavy truck includes a tube beam support, a round tube beam 6, a U-shaped bracket 8 and a transmission shaft hanging bracket 10;

[0027] The tubular beam support includes a right tubular beam support 7 and a left tubular beam support 12 which have the same structure and are symmetrically arranged; the two ends of the circular tubular beam 6 are respectively fixedly mounted on the right tubular beam support 7 and the left tubular beam support 12; the two U-shaped brackets 8 are fixed on the circular tubular beam 6; the transmission shaft hanging bracket 10 is mounted on the two U-shaped brackets 8.

[0028] As an improvement of the embodiment, Figure 2-Figure 4 As shown, since the structures of the right support 7 of the pipe beam and the left support 12 of the pipe beam are the same, for the convenience of description, the structure of the right support 7 of the pipe beam is described as an example:

[0029] The thickness of the right support 7 of the pipe beam is uneven. According to the stress conditions, a thickened portion 7-1 is provided for the part with greater stress, such as the installation hole on the right support 7 of the pipe beam (for connecting the right longitudinal beam 2 of the frame) and the connection between the right support 7 of the pipe beam and the round pipe beam 6. The remaining parts with less stress are thinned to form a pipe beam support with uneven thickness. Compared with the conventional pipe beam support with uniform structure, the left and right supports of the pipe beam of the utility model are stronger and lighter. In addition, the left and right supports of the pipe beam are formed by casting or forging.

[0030] As an improvement of the embodiment, Figure 3 , Figure 4As shown, the right support 7 of the tubular beam is provided with a limiting convex ring 7-2 which cooperates with the circular tubular beam 6. The diameter of the limiting convex ring 7-2 is smaller than the diameter of the circular tubular beam 6, so that the limiting convex ring 7-2 can be installed inside the circular tubular beam 6. The connection between the circular tubular beam 6 and the right support 7 of the tubular beam is fixed by circumferential welding. By installing the limiting convex ring 7-2 inside the circular tubular beam 6 and cooperating with the limiting protrusion 7-3 set at the end of the limiting convex ring 7-2, the circular tubular beam 6 is limited. This can effectively prevent the circular tubular beam 6 from moving to both ends, and at the same time avoid cracking of the weld between the circular tubular beam 6 and the right support 7 of the tubular beam, thereby enhancing the strength of the frame circular tubular beam assembly 3.

[0031] As an improvement of the embodiment, Figure 1 , Figure 2 As shown, a welding nut 9 is provided on one side of the U-shaped bracket 8 close to the round tube beam 6, and the transmission shaft hanging bracket 10 is fixed to the U-shaped bracket 8 by means of mounting bolts 11. By providing the welding nut 9, the assembly efficiency of the mounting components can be improved.

[0032] As an improvement of the embodiment, the U-shaped bracket 8 is welded on the round tube beam 6, which is easy to install and has high stability.

[0033] In addition, the utility model also provides a vehicle, on which the frame round tube beam assembly for a heavy truck is installed. Further, the vehicle can be a heavy truck.

[0034] As an improvement of the embodiment, the vehicle includes a left longitudinal beam 1, a right longitudinal beam 2 and a round tube beam assembly 3. The right tube beam support 7 at one end of the round tube beam assembly 3 is connected to the right longitudinal beam 2 of the frame through a connecting bolt 5 and a connecting nut 4, and the left tube beam support 12 at the other end is connected to the left longitudinal beam 1 of the frame through a connecting bolt 5 and a connecting nut 4. The connecting bolt 5 and the connecting nut 4 are used to cooperate and connect, so that the installation position of the round tube beam assembly 3 on the left and right longitudinal beams of the frame can be flexibly adjusted according to needs.

[0035] like Figure 2 and Figure 3 As shown, the installation process is:

[0036] The right support 7 and the left support 12 of the tube beam are respectively inserted into the inner wall of the circular tube beam 6. The connection between the two ends of the circular tube beam 6 and the right support 7 and the left support 12 of the tube beam is fixed by circumferential welding. The limiting convex rings and limiting protrusions on the right support 7 and the left support 12 of the tube beam can effectively prevent the circular tube beam 6 from moving to both ends, avoid weld cracking, and enhance the strength of the frame circular tube beam assembly 3; the U-shaped bracket 8 is welded and fixed to the circular tube beam 6, and the welding nut 9 is fixed to the inner side of the U-shaped bracket 8 by spot welding. The welding nut 9 can facilitate the installation of components and improve assembly efficiency; the transmission shaft hanging bracket 10 is assembled on the U-shaped bracket 8 by the mounting bolts 11, and can be used to install and fix the transmission shaft;

[0037] When the transmission shaft hanging bracket 10 is not assembled, the U-shaped bracket 8 can also be used to install other components, thereby ensuring the versatility of the frame round tube beam assembly 3.

[0038] The utility model discloses a heavy-duty truck frame round tube beam assembly, which can effectively prevent the round tube beam from moving toward both ends and avoid weld cracking through the left and right tube beam supports, thereby enhancing the strength of the frame round tube beam assembly. The round tube beam is superior in strength and torsion resistance to ordinary plate beams. A U-shaped bracket is installed on the round tube beam to provide assembly holes, which is convenient for installing vehicle components.

[0039] In addition, those skilled in the art will understand that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments also means being within the scope of protection of the present utility model and forming different embodiments. For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by the present application.
