Description

Technical Field

[0001] This invention relates to the field of vehicle component assembly technology, and more particularly to a vehicle frame crossbeam, and also to a vehicle frame. Background Technology

[0002] The chassis is the mounting base for all automotive assemblies, connecting the engine, body, and other assemblies into a cohesive whole, forming a complete vehicle. It requires sufficient strength to ensure that under various complex stress conditions, the assemblies on the chassis and platform do not prematurely fail or lose their normal working capacity due to deformation or fatigue. It also needs appropriate torsional stiffness to ensure the vehicle's adaptability to uneven road surfaces, improving ride comfort and handling. The chassis crossbeams, as key components of the chassis, primarily connect the longitudinal beams, forming a complete frame that ensures the chassis's load-bearing capacity, possessing sufficient strength and torsional stiffness.

[0003] To meet requirements such as lightweighting and cost reduction, existing heavy-duty commercial vehicle chassis often adopt variable-width frames. However, the crossbeams in the deformation zone of such variable-width frames still suffer from uneven stress distribution and poor structural stability. To address these issues, the crossbeams are typically designed to be quite complex. Consequently, existing crossbeams in the deformation zone often suffer from numerous assembly parts, heavy weight, poor reliability, and occupy significant chassis space. Summary of the Invention

[0004] This invention provides a frame crossbeam to solve the problems of numerous assembly parts, heavy weight, poor reliability, and large chassis space occupation in the existing deformation zone frame crossbeams. It achieves a frame crossbeam structure with simple structure, fewer assembly parts, smaller chassis space occupation, and better strength and stability.

[0005] The present invention provides a crossbeam for a vehicle frame, comprising a crossbeam body, end beams and longitudinal beam connecting parts. Each end beam is connected to an end beam at both ends of the crossbeam body, and each end beam is connected to a longitudinal beam connecting part at the end opposite to the crossbeam body. The lower surface of the crossbeam body and the lower surfaces of the two end beams are curved surfaces, and the angle between the longitudinal beam connecting part and the upper surface of the crossbeam body is an obtuse angle.

[0006] According to the present invention, the lower surface of the crossbeam body and the lower surfaces of the two end beams are both curved, and the longitudinal beam connecting part and the end beam are arranged to realize that the transverse structure of the vehicle frame is arched, so as to ensure the strength, rigidity and stability of the crossbeam of the vehicle frame. The vertical arrangement of the longitudinal beam connecting part and the upper surface of the crossbeam body ensures the reliable connection between the crossbeam of the vehicle frame and the longitudinal beam of the vehicle frame.

[0007] In addition, a crossbeam of a vehicle frame according to the present invention may also have the following additional technical features:

[0008] In some embodiments of the present invention, each end beam includes an end connector and a side support plate. An end connector is connected to each end of the beam body, and a side support plate is connected to each side of each end connector. Each end connector is connected to the longitudinal beam connection part through the side support plate.

[0009] In the interconnected side support plate and longitudinal beam connection, the width of the side support plate gradually increases from the end furthest from the longitudinal beam connection to the end closest to the longitudinal beam connection.

[0010] By adopting the above embodiments, the width of the side support plate gradually increases from the end away from the longitudinal beam connection to the end closer to the longitudinal beam connection, which can increase the strength and stability of the frame crossbeam.

[0011] In some embodiments of the present invention, the width of both end connectors gradually increases from top to bottom, and the width of each end connector gradually increases from the end closest to the crossbeam body to the end furthest from the crossbeam body.

[0012] By adopting the above embodiments, the strength and stability of the frame crossbeam can be further increased by setting the width of the connector.

[0013] In some embodiments of the present invention, the width of the beam body gradually increases from the middle to both ends.

[0014] By adopting the above embodiments, the design of gradually increasing width of the beam body from the middle to both ends can decompose the force on the beam, thereby enabling the beam to bear a larger force.

[0015] In some embodiments of the present invention, the crossbeam body, the end beams, and the longitudinal beam connection are integrally formed.

[0016] By adopting the above embodiments, the one-piece molding design allows the crossbeam to be injection molded, which increases the convenience of processing the crossbeam while achieving a relatively simple structure.

[0017] In some embodiments of the present invention, each longitudinal beam connection includes a longitudinal beam connecting plate, a first connecting lug, a second connecting lug, and a third connecting lug. The upper end of each longitudinal beam connecting plate is connected to an end beam, and the side of each longitudinal beam connecting plate is provided with a first connecting lug, a second connecting lug, and a third connecting lug.

[0018] By adopting the above embodiments, the provision of the first connecting ear, the second connecting ear, and the third connecting ear increases the convenience of connecting the crossbeam and the longitudinal beam of this frame.

[0019] In some embodiments of the present invention, each end connector includes a top connecting portion and a vertical connecting plate. A vertical connecting plate is connected to each side of the top connecting portion. The top connecting portion and the two vertical connecting plates are connected to the crossbeam body. A side support plate is connected to the side of each vertical connecting plate away from the top connecting portion.

[0020] By adopting the above embodiments, the strength and stability of the end connector are ensured by the provision of a top connecting part and a vertical connecting part.

[0021] In some embodiments of the present invention, a bottom mounting portion is provided on the lower surface of the crossbeam body, a first side mounting portion is provided on one side of the crossbeam body, and a second side mounting portion is provided on the other side of the crossbeam body.

[0022] By adopting the above embodiments, the first side mounting part and the second side mounting part provide an installation environment for the valve body bracket, pipeline fixing bracket, drive shaft support angle plate and bottom wire harness bracket, and facilitate the installation of the valve body bracket, pipeline fixing bracket, drive shaft support angle plate and bottom wire harness bracket.

[0023] In some embodiments of the present invention, a first mounting hole is provided on the bottom mounting portion, a second mounting hole is provided on the first side mounting portion, a third mounting hole is provided on the second side mounting portion, and a fourth mounting hole is provided on the top connecting portion.

[0024] By adopting the above embodiments, the valve body bracket, pipeline fixing bracket, drive shaft support angle plate, and bottom wiring harness bracket can all be connected to the crossbeam of the vehicle frame by screwing through the first mounting hole, second mounting hole, third mounting hole, and fourth mounting hole, making the connection relatively convenient.

[0025] According to a frame of the present invention, in addition to using all the technical features of the frame crossbeam of the present invention, it also includes a left longitudinal beam, a right longitudinal beam and a connecting plate. The frame crossbeam is disposed between the left longitudinal beam and the right longitudinal beam. A connecting plate is provided on the side of both the left longitudinal beam and the right longitudinal beam, and the two connecting plates are respectively connected to the two top connecting parts one by one.

[0026] By adopting the above embodiments, the connection plate is set in conjunction with the left longitudinal beam of the frame and the left longitudinal beam of the frame being connected to the crossbeam of the frame, which can ensure the stability of the connection between the crossbeam and the longitudinal beam of the frame.

[0027] In summary, this application includes the following beneficial technical effects: First, by setting the lower surface of the crossbeam body and the lower surfaces of the two end beams to be curved, and by combining the longitudinal beam connection and the end beam, the transverse structure of this vehicle frame is arched, so as to ensure the strength, rigidity and stability of the crossbeam of this vehicle frame.

[0028] Secondly, by setting the angle between the longitudinal beam connecting part and the upper surface of the crossbeam body to be an obtuse angle, the reliable connection between the crossbeam and the longitudinal beam of the frame is ensured, while further decomposing the stress and alleviating stress concentration, thereby further increasing the stability of the crossbeam of the frame.

[0029] Third, the crossbeam has a simple structure and fewer assembly parts. By varying the dimensions of the crossbeam at various positions and designing a curved lower surface, it occupies less chassis space, leaving more installation space for other components. Attached Figure Description

[0040] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0041] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “” used herein may also indicate the inclusion of the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated, unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0042] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0043] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may also be rotated 90 degrees or in other orientations, and the spatial relative descriptors used in the text will be interpreted accordingly.

[0044] like Figures 1 to 4 As shown, according to an embodiment of the first aspect of the present invention, a frame crossbeam is provided, including a crossbeam body 1, end beams 2 and longitudinal beam connecting parts 3. An end beam 2 is connected to each end of the crossbeam body 1, and a longitudinal beam connecting part 3 is connected to the end of each end beam 2 facing away from the crossbeam body 1. The lower surface of the crossbeam body 1 and the lower surfaces of the two end beams 2 are both curved surfaces, and the angle between the longitudinal beam connecting part 3 and the upper surface of the crossbeam body 1 is an obtuse angle.

[0045] In the above embodiments, it should be noted that the crossbeam body 1, the end beams 2, and the longitudinal beam connecting parts 3 are integrally formed; the crossbeam body 1 includes a middle connecting top plate 11, a middle connecting bottom plate 12, and two middle connecting side plates 16. The middle connecting top plate 11, the middle connecting bottom plate 12, and the two middle connecting side plates 16 enclose a quadrilateral hollow tubular structure. The width of the middle connecting top plate 11 and the middle connecting bottom plate 12 gradually increases from the middle to both ends. The middle connecting top plate 11 is a flat plate, and the cross-sectional shape of the middle connecting bottom plate 12 is arc-shaped so that the lower surface of the crossbeam body 1 is curved. The width of the two middle side connecting plates 16 increases sequentially from top to bottom; the crossbeam body 1 is provided with a burr structure on the front, back, left, and right sides.

[0046] The technical effect achieved by the above embodiment is that the crossbeam body 1 is a tubular structure formed by the intermediate connecting top plate 11, intermediate connecting bottom plate 12 and two intermediate connecting side plates 16, which can ensure that the frame is lightweight to the greatest extent while ensuring stability and strength.

[0047] The width of both the intermediate connecting top plate 11 and the intermediate connecting bottom plate 12 gradually increases from the middle to both ends, which can decompose the forces from the left and right directions of the vehicle as well as the forces from the front and rear directions of the vehicle, so that the crossbeam body 1 can withstand greater forces from the left and right directions and the front and rear directions of the vehicle. The curved surface of the lower surface of the crossbeam body 1, combined with the width of the two intermediate side connecting plates 16 increasing from top to bottom, can further decompose the forces from the up and down directions, left and right directions and the front and rear directions of the vehicle, so that the crossbeam body 1 can withstand greater forces from the up and down direction of the vehicle, while further increasing the forces that the crossbeam body 1 can withstand from the front and rear directions and the left and right directions of the vehicle.

[0048] By designing the lower surfaces of both end beams 2 as curved surfaces, forces from the left and right directions as well as forces from the up and down directions of the vehicle can be decomposed. The forces are initially decomposed before they enter the crossbeam body 1, so as to maximize the load-bearing capacity of the crossbeam of the vehicle frame.

[0049] In summary, by using the intermediate connecting top plate 11, intermediate connecting bottom plate 12, and two intermediate connecting side plates 16 in conjunction with the end beam 2, the forces from the vehicle coming from all directions received by the crossbeam of this frame can be decomposed to the maximum extent, thereby increasing the torsional strength and bending strength of the crossbeam of the frame, and thus increasing the reliability and stability of the crossbeam of this frame.

[0050] The curved design of the lower surface of the crossbeam body 1 and the lower surfaces of the two end beams 2 provides ample installation space for the bottom drive shaft 53.

[0051] The design of gradually increasing widths of the intermediate connecting top plate 11 and intermediate connecting bottom plate 12 from the middle to both ends further reduces the weight of the frame crossbeams, achieving the goal of lightweighting.

[0052] The design effectively solves the problem of stress concentration at both ends of the beam assembly by having the width of the intermediate connecting top plate 11 and intermediate connecting bottom plate 12 gradually increase from the middle to both ends, the lower surface of the beam body 1 and the lower surfaces of the two end beams 2 are curved surfaces, and the beam body 1 is provided with burrs on the front, back, left and right sides.

[0053] In addition, the crossbeam has a simple structure and fewer assembly parts. By varying the dimensions of the crossbeam at various positions and designing a curved lower surface, it occupies less chassis space, leaving more installation space for other components.

[0054] Optional, such as Figure 2 and Figure 3 As shown, each end beam 2 includes an end connector and a side support plate 22. An end connector is connected to each end of the crossbeam body 1, and a side support plate 22 is connected to each side of each end connector. Each end connector is connected to the longitudinal beam connection part 3 through the side support plate 22.

[0055] In the interconnected side support plate 22 and longitudinal beam connection 3, the width of the side support plate 22 gradually increases from the end away from the longitudinal beam connection 3 to the end closer to the longitudinal beam connection 3.

[0056] The width of both end connectors gradually increases from top to bottom, and the width of each end connector gradually increases from the end closest to the crossbeam body 1 to the end furthest from the crossbeam body 1.

[0057] Each end connector includes a top connecting part 21 and a vertical connecting plate 23. A vertical connecting plate 23 is connected to each side of the top connecting part 21. The top connecting part 21 and the two vertical connecting plates 23 are connected to the crossbeam body 1. A side support plate 22 is connected to the side of each vertical connecting plate 23 away from the top connecting part 21.

[0058] In the above optional embodiments, it should be noted that each end connector also includes a bottom connecting part 26, and the two vertical connecting plates 23, the top connecting part 21 and the bottom connecting part 26 are arranged to form a quadrilateral tubular structure.

[0059] The top connecting part 21 is connected to the middle connecting top plate 11, the bottom connecting part 26 is connected to the middle connecting bottom plate 12, and the vertical connecting plate 23 is connected to the middle connecting side plate 16 in a corresponding manner.

[0060] The width of the top connecting part 21 and the width of the bottom connecting part 26 gradually increase from the end near the crossbeam body 1 to the end away from the crossbeam body 1; the distance between the two vertical connecting plates 23 gradually increases from top to bottom and the distance between the two vertical connecting plates 23 gradually increases from the end near the crossbeam body 1 to the end away from the crossbeam body 1.

[0061] It also includes a collar hole 24, a part of which is formed in the middle connecting base plate 12, and another part of which is formed in the bottom connecting part 26. The collar hole 24 is irregularly circular in shape. The diameter of the part of the collar hole 24 located in the middle connecting base plate 12 gradually increases from the side closer to the middle of the middle connecting base plate 12 to the side farther away from the middle connecting base plate 12. The outer periphery of the collar hole 24 is formed with an arc-shaped transition part 25.

[0062] The top connecting part 21, the middle connecting top plate 11, the bottom connecting part 26, the middle connecting bottom plate 12, the vertical connecting plate 23, and the middle connecting side plate 16 are integrally cast from high-strength and tough ductile iron material. The side support plate 22 and the vertical connecting plate 23 are welded together, as are the side support plate 22 and the longitudinal beam connecting part 3.

[0063] The advantages of the above optional embodiments are as follows: the collar hole 24 and the transition part 25 can effectively reduce stress concentration and further reduce the weight of the crossbeam support; in addition, the collar hole 24 can provide sufficient operating space for the crossbeam of the frame to be assembled on the frame, which facilitates the disassembly and assembly of the crossbeam of the frame and improves maintenance convenience.

[0064] The quadrilateral tubular structure formed by the two vertical connecting plates 23, the top connecting part 21, and the bottom connecting part 26, combined with the quadrilateral hollow tubular structure formed by the intermediate connecting top plate 11, the intermediate connecting bottom plate 12, and the two intermediate connecting side plates 16, achieves a variable-size tubular structure for the entire frame beam. This ensures strength and stability while minimizing stress concentration and meeting lightweight requirements.

[0065] By gradually increasing the width of the side support plate 22 from the end away from the longitudinal beam connection 3 to the end near the longitudinal beam connection 3, and by gradually increasing the width of both end connectors from top to bottom, and by gradually increasing the width of each end connector from the end near the crossbeam body 1 to the end away from the crossbeam body 1, the force from the vehicle can be further decomposed in all directions, so that the crossbeam of this frame can withstand very large impact forces and meet performance requirements.

[0066] The side support plate 22 can further alleviate the stress concentration of the crossbeam of the frame.

[0067] Optional, such as Figures 1 to 4As shown, the width of the beam body 1 gradually increases from the middle to both ends.

[0068] Optional, such as Figures 1 to 7 As shown, each longitudinal beam connection part 3 includes a longitudinal beam connection plate 34, a first connecting ear 31, a second connecting ear 32 and a third connecting ear 33. The upper end of each longitudinal beam connection plate 34 is connected to the end beam 2, and the side of each longitudinal beam connection plate 34 is provided with a first connecting ear 31, a second connecting ear 32 and a third connecting ear 33.

[0071] The surfaces of the first connecting ear 31, the second connecting ear 32, and the third connecting ear 33 can be machined or exempted from machining to improve casting precision, thereby reducing assembly errors.

[0072] The fifth mounting hole 311, the sixth mounting hole 321 and the seventh mounting hole 331 are all threaded holes to increase the convenience of connecting this crossbeam to the frame.

[0073] The beneficial effects of the above optional embodiments are as follows: First, by having the first connecting ear 31 and one of the second connecting ears 32 arranged in a stepped manner, and the third connecting ear 33 and another second connecting ear 32 arranged in a stepped manner, it is achieved that the multiple fifth mounting holes 311 and multiple sixth mounting holes 321, as well as the fifth mounting holes 311 and multiple seventh mounting holes 331, are all arranged in a trapezoidal manner, so as to ensure that the crossbeam of this frame occupies less space while achieving a higher connection force when connected to the frame, thereby ensuring the reliability of the connection of the crossbeam of this frame.

[0074] Optional, such as Figures 1 to 7As shown, the bottom mounting part 13 has a first mounting hole 131, the first side mounting part 14 has a second mounting hole 141, the second side mounting part 15 has a third mounting hole 151, and the top connecting part 21 has a fourth mounting hole 211.

[0075] In the above optional embodiments, it should be noted that the bottom mounting portion 13, the first side mounting portion 14, and the second side mounting portion 15 are all boss structures to reduce the machining area and save manufacturing costs.

[0076] The first mounting hole 131, the second mounting hole 141, the third mounting hole 151, and the fourth mounting hole 211 are all threaded holes.

[0077] Each top connection 21 has six fourth mounting holes 211. In each group of fourth mounting holes 211, three of the six fourth mounting holes 211 are arranged in a triangular pattern, and the other three fourth mounting holes 211 are arranged in a straight line outside the three fourth mounting holes 211 arranged in a triangular pattern. The fourth mounting holes 211 are also used to connect the crossbeam of this frame to the frame.

[0078] The second mounting hole 141 is used to connect the ABS control valve bracket 51 by bolts. The ABS control valve bracket 51 is used to install the ABS control valve. The third mounting hole 151 is used to connect the support angle plate of the drive shaft 50 and the heating water pipe 52 by bolts. The first mounting hole 131 is used to connect the bottom wiring harness bracket 54 by bolts. The brake line 55 and the whole vehicle wiring harness are all tied to the bottom wiring harness bracket 54 by bracing, so that the brake line 55 and the whole vehicle wiring harness can cross the right longitudinal beam 41 and the left longitudinal beam 42 of the frame, ensuring the connection of the left and right chassis wiring harnesses, facilitating the straightening of pipelines, effectively solving the safety hazards of wiring harness friction, and improving the overall vehicle quality.

[0080] The advantages of the above optional embodiments are as follows: by arranging the six fourth mounting holes 211 in a triangular and straight-line shape in each group, the six fourth mounting holes 211 are combined to form four triangles, and the stability of the triangles is used to ensure the stability of the connection between the crossbeam and the frame.

[0081] The coordinated mounting holes 131, 141, 151, 211, 311, 321, and 331 ensure a reliable and stable connection between the frame crossbeam and the frame, while also enabling the reliable installation of the drive shaft 50, ABS control valve, heating water pipe 52, brake line 55, and vehicle wiring harness. This integrated design provides installation space and convenient adjustment for these components. It overcomes the limitations of existing products with limited functionality, and the multiple mounting holes on the frame crossbeam allow for the assembly of various parts such as the drive shaft 50, ABS control valve, heating water pipe 52, and brake line 55, improving assembly efficiency. This reduces the number of vehicle parts, saves production costs, increases production efficiency, and effectively solves problems such as loose rivets and dimensional inconsistencies.

[0082] In summary, the crossbeam of this vehicle frame is integrally cast from high-strength and tough ductile iron material, achieving high quality, lightweight, and cost reduction. The arched structure improves the overall vehicle layout space, enhances the stress condition in the deformation zone of the frame, and ensures the safety and service life of the frame. The multiple sets of mounting holes on the crossbeam of the frame allow for the offline assembly of various parts, improving assembly efficiency. At the same time, it is aesthetically pleasing and maintainable, with a more optimized structure, making it suitable for widespread application.

The frame crossbeam is disposed between the left longitudinal beam 42 and the right longitudinal beam 41. A connecting plate 43 is provided on the side of both the left longitudinal beam 42 and the right longitudinal beam 41.

[0085] The beneficial effects of the above optional embodiments are as follows: the connection plate 43 enables the frame crossbeam to be positioned on both sides and above the frame crossbeam when connected to the frame left longitudinal beam 42 and frame right longitudinal beam 41. The fourth mounting hole 211, the fifth mounting hole 311, the sixth mounting hole 321 and the seventh mounting hole 331 cooperate to form a triangular mounting and positioning structure, so as to achieve reliable and stable connection between the frame crossbeam and the frame left longitudinal beam 42 and frame right longitudinal beam 41.

[0086] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
