[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] In the prior art, a vehicle's crossbeam needs to connect to multiple functional components. To facilitate the connection between the functional components and the crossbeam, corresponding functional component mounting portions are typically pre-installed on the crossbeam. For example, a vehicle's crossbeam needs to connect to a longitudinal beam, so a longitudinal beam mounting plate is typically pre-installed on the crossbeam to connect the longitudinal beam. In the prior art, the functional component mounting portions (e.g., longitudinal beam mounting plates) are typically mounted on the crossbeam using corresponding connectors (e.g., bolts). This not only requires multiple installation steps, but also makes the crossbeam and the functional component mounting portions mounted on the crossbeam heavier overall, hindering the vehicle's lightweight design.

[0033] like Figure 1-Figure 3 As shown, an embodiment of the present application provides a crossbeam that can be used for a vehicle frame, and is particularly suitable for a vehicle frame with an air suspension.

[0034] The crossbeam provided in the embodiment of the present application includes a tubular beam 100 and a plurality of functional component mounting portions. The plurality of functional component mounting portions and the tubular beam 100 are an integrated structure. That is, the crossbeam provided in the embodiment of the present application is an integrated structure. Optionally, the crossbeam can be an integrated structure cast by casting. Of course, the crossbeam can also be processed into an integrated structure by other processing techniques.

[0035] The functional component mounting portion is used to connect functional components of the vehicle. Specifically, the multiple functional component mounting portions include at least a longitudinal beam mounting portion 200 for connecting to a longitudinal beam. In this case, integrating the functional component mounting portion into the tubular beam 100 reduces the number of connectors used to connect the tubular beam 100 and the functional component mounting portion, thereby reducing redundant parts and cross-functional integration, facilitating lightweight vehicle design and achieving vehicle weight reduction. Furthermore, integrating the functional component mounting portion into the tubular beam 100 through one-piece processing reduces installation steps, thereby reducing processing costs.

[0036] Furthermore, at least one of the plurality of functional component mounting portions is provided with a weight-reducing structure, which contributes to the lightweight design of the crossbeam and thus helps to achieve lightweighting of the vehicle.

[0037] In the embodiment of the present application, multiple functional component mounting parts are integrated on the tubular beam through one-piece processing to form a crossbeam, which saves the connecting parts required to install the functional component mounting parts on the tubular beam 100, and reduces the weight of the tubular beam 100 and the overall weight formed by the connection of multiple functional component mounting parts. In addition, at least one of the multiple functional component mounting parts is provided with a weight-reducing structure, which also helps to reduce the weight of the crossbeam. Therefore, using the crossbeam in the embodiment of the present application for a vehicle is conducive to achieving lightweighting of the vehicle.

[0038] The longitudinal beam mounting portion 200 may include a longitudinal beam mounting plate 210 and longitudinal beam mounting holes 220 provided on the longitudinal beam mounting plate 210. The number of longitudinal beam mounting holes 220 on each longitudinal beam mounting plate 210 may be multiple, and the multiple longitudinal beam mounting holes 220 may be arranged in a matrix or distributed along the circumference of the longitudinal beam mounting plate 210. Optionally, the longitudinal beam mounting holes 220 may be through holes or threaded holes.

[0039] There are at least two longitudinal beam mounting parts 200, which are respectively provided at both ends of the tubular beam 100. Optionally, there are two longitudinal beam mounting parts 200, which are respectively provided at both ends of the tubular beam 100 along the longitudinal direction of the tubular beam 100.

[0040] Each longitudinal beam mounting portion 200 is provided with a weight-reducing structure, and the structure of the weight-reducing structure can be of various types. In an optional embodiment, the weight-reducing structure can include a weight-reducing notch provided on the longitudinal beam mounting plate 210, such as a weight-reducing notch located at a corner of the longitudinal beam mounting plate 210, and the weight-reducing notch avoids the longitudinal beam mounting hole 220.

[0041] In an optional embodiment, the weight reduction structure may include a weight reduction hole 500 provided on the longitudinal beam mounting plate 210, wherein the weight reduction hole 500 avoids the longitudinal beam mounting hole 220. This weight reduction structure is simple in structure and can simplify the structure of the casting mold.

[0042] Among the multiple longitudinal beam mounting parts 200 , the longitudinal beam mounting plate 210 of one longitudinal beam mounting part 200 may have one or more weight reduction holes 500 , or each longitudinal beam mounting plate 210 of each longitudinal beam mounting part 200 may have one or more weight reduction holes 500 .

[0043] In a further technical solution, the tubular beam 100 has a tubular cavity, and the longitudinal beam mounting plate 210 includes an annular plate. The annular plates of the two longitudinal beam mounting portions 200 are respectively provided at both ends of the tubular beam 100, and the annular plates are arranged around the end openings of the tubular cavity. Designing the longitudinal beam mounting plate 210 as an annular plate helps reduce the weight of the longitudinal beam mounting plate 210, thereby reducing the weight of the crossbeam. Of course, in this embodiment, the weight reduction holes 500 can be provided in the annular plate. The number of weight reduction holes 500 on the annular plate is multiple, for example, two, and the multiple weight reduction holes 500 are symmetrically distributed about the center of the annular plate to ensure the strength of the longitudinal beam mounting plate 210.

[0044] In the prior art, a longitudinal beam mounting plate used to connect longitudinal beams is typically provided with 36 longitudinal beam mounting holes 220. In the embodiment of the present application, the number of longitudinal beam mounting holes 220 on each longitudinal beam mounting plate 210 can be 18 to 22, such as 18, 20, or 22. Thus, compared to the prior art, the embodiment of the present application reduces the number of longitudinal beam mounting holes 220, which helps reduce assembly time and improve vehicle installation efficiency when the crossbeam is used in a vehicle. Furthermore, reducing the number of longitudinal beam mounting holes 220 also reduces the number of connectors connecting the longitudinal beam mounting portion 200 and the longitudinal beam, which also contributes to the lightweight design of the vehicle and helps achieve vehicle lightweighting.

[0045] The crossbeam includes multiple functional component mounting parts. In the embodiment of the present application, the multiple functional component mounting parts may also include a V-push bracket 300. The V-push bracket 300 is used to install the V-push assembly. The V-push bracket 300 may include multiple (for example, two) V-push mounting bosses 310 protruding from the pipe beam 100. The V-push mounting bosses 310 are provided with V-push mounting threaded holes 330. The multiple V-push mounting bosses 310 form an installation space 320 for the end of the V-push assembly to extend into.

[0046] There are at least two V-push brackets 300 . The at least two V-push brackets 300 are located on the same side of the tubular beam 100 and are spaced apart along the length direction of the tubular beam 100 .

[0047] In this case, the V-push assembly can be matched with the V-push mounting threaded hole 330 through bolts to achieve the installation of the V-push assembly and the crossbeam, and this structure does not require the use of nuts that match the bolts. When this crossbeam is applied to a vehicle, it helps to achieve lightweighting of the vehicle.

[0048] Optionally, the number of V-push brackets 300 can be four, two of which are arranged on one side of the pipe beam 100 and are spaced apart along the length direction of the pipe beam 100, and the other two are arranged on the other side of the pipe beam 100 and are spaced apart along the length direction of the pipe beam 100.

[0049] The crossbeam includes multiple functional component mounting parts. In an embodiment of the present application, the multiple functional component mounting parts may include a valve body mounting part, which is used to mount a valve body, such as a brake valve body. The valve body mounting part may be provided with a valve body mounting threaded hole 420 for mounting the valve body. The valve body may have a mounting bracket. The mounting bracket of the valve body may cooperate with the valve body mounting threaded hole 420 through bolts to achieve the installation of the valve body and the crossbeam. This structure does not require the use of nuts that match the bolts. When this crossbeam is applied to a vehicle, it contributes to the lightweight design of the vehicle and helps to achieve the lightweight design of the vehicle.

[0050] In an optional embodiment, the valve body mounting threaded hole 420 can be directly provided on the pipe wall of the pipe beam 100 .

[0051] In a preferred embodiment, the valve body mounting portion may include a valve body mounting protrusion 410 protruding from the tubular beam 100, and the valve body mounting threaded hole 420 may be provided in the valve body mounting protrusion 410. With this structure, the axial length of the valve body mounting threaded hole 420 can be increased, which helps to improve the connection strength and stability between the crossbeam and the valve body when the crossbeam is used in a vehicle.

[0052] The number of valve body mounting protrusions 410 and valve body mounting threaded holes 420 is the same and corresponds one to one. Optionally, the number of valve body mounting protrusions 410 and valve body mounting threaded holes 420 can be eight, four of which are arranged on one side of the pipe beam 100 and the other four are arranged on the other side of the pipe beam 100.

[0053] In the embodiment of the present application, the pipe beam 100 has a lumen and a drainage hole 600 communicating with the lumen. The drainage hole 600 can be provided at the bottom of the pipe beam 100. The number of drainage holes 600 can be two, one, or three. The present application does not impose any restrictions on the number of drainage holes 600. In this case, accumulated water inside the pipe beam 100 can be drained away, reducing the risk of crossbeam corrosion.

[0054] In the embodiment of the present application, the cross-section of the tubular beam 100 may be elliptical to improve the torsional stiffness of the tubular beam 100. It should be noted that the cross-section of the tubular beam 100 refers to the cross-section perpendicular to the longitudinal direction. Of course, in other embodiments, the cross-section of the tubular beam 100 may also be a circular or other shape.

[0055] The crossbeam in the embodiment of the present application can be an integral cast crossbeam. Optionally, the crossbeam can be cast as a whole from QT1050 (ductile iron 1050) material. A crossbeam with this structure is not only easy to install but also lightweight. Applying it to a vehicle can contribute to the lightweight design of the vehicle and help achieve lightweighting of the vehicle.

[0056] Based on the above-mentioned crossbeam, an embodiment of the present application further provides a vehicle frame, which includes the above-mentioned crossbeam. Since the vehicle frame includes the above-mentioned crossbeam, the beneficial effects of the frame brought by the crossbeam can be found in the above content and will not be repeated here.

[0057] Based on the above-mentioned crossbeam, an embodiment of the present application further provides a vehicle, which includes the above-mentioned crossbeam. Since the vehicle has the above-mentioned crossbeam, the beneficial effects brought by the crossbeam to the vehicle can be found in the above content and will not be repeated here.

[0058] The vehicle in the embodiment of the present application can be a family car or a commercial vehicle, such as a tractor. The crossbeam in the embodiment of the present application is applied to the vehicle, and redundant components are reduced through integrated design to achieve cross-functional integration and achieve vehicle lightweighting.

[0059] In recent years, with rising oil prices and the worsening global warming, countries around the world have paid greater attention to environmental issues caused by energy and carbon dioxide emissions. Commercial vehicle carbon dioxide emissions account for approximately 60% of all vehicle emissions; a 49-ton diesel heavy-duty truck emits as much carbon dioxide as 40 gasoline-powered cars. Therefore, when the crossbeams described in the embodiments of this application are applied to vehicles, particularly commercial vehicles, they can reduce vehicle weight, achieve energy conservation and emission reductions, and simultaneously increase payload capacity while reducing vehicle weight, thereby improving transportation efficiency and reducing transportation costs.
