[0029] In the design process of automobile frame, the strength and functionality of cross beam assembly are crucial factors. However, the existing cross beam assembly design is often cumbersome and complex, which not only increases the manufacturing cost, but also brings many challenges to the assembly process. Specifically, the existing cross beam assembly usually adopts a combined cross beam structure and is equipped with multiple thrust rod supports. Although this design can meet certain strength and functional requirements, it also leads to a complex and tedious frame assembly process. The assembly workers need to make multiple adjustments and corrections to ensure the correct installation position of each component.

[0030] In addition, in the actual production process, due to manufacturing errors, assembly errors and other environmental factors, the design tolerance of the system is difficult to effectively control and guarantee. This further leads to the difficulty in ensuring the accuracy of the suspension hard point size, making the assembly of key components such as thrust rods very inconvenient. In order to ensure the correct installation of these components, additional debugging and correction steps are usually required, greatly increasing the cost and time of production and maintenance.

[0031] In summary, the cross beam assembly design in the prior art has the problems of complex structure, difficult assembly and tolerance control difficulty. Therefore, an improved cross beam assembly design is needed to simplify the assembly process and improve the accuracy and reliability of the system.

[0032] Based on the problems in the prior art, please refer to Figs. 1 to 4 The utility model embodiment provides a kind of integrated frame cross beam 10, applied to frame field, especially suitable for rear double bridge group frame.The integrated frame cross beam 10 provided by the utility model embodiment adopts integrated design, integrates thrust rod support 300 with cross beam, reduces connecting point and tooling demand, improves manufacturing and assembly accuracy, enhances the stability and strength of frame.In addition, cross beam design also includes weight reduction hole 110 and function hole, to reduce system weight and facilitate installation brake valve body, electrical element and fixed wire harness, improve the multifunctionality of integrated frame cross beam 10.

[0033] In detail, integrated frame cross beam 10 includes integrally formed first connecting beam 100, second connecting beam 200 and thrust rod support 300.

[0034] The two long sides of the first connecting beam 100 are connected to two second connecting beams 200 respectively so that the cross section is in the shape of "I". Thrust rod supports 300 are provided on both sides of the length direction of the first connecting beam 100. The two thrust rod supports 300 located on the same side wall of the first connecting beam 100 are used together to connect with the thrust rod.

[0035] It is worth mentioning that the thrust rod connected to the thrust rod support 300 is usually a V-shaped thrust rod.

[0036] In this embodiment, the first connecting beam 100, the second connecting beam 200, and the thrust rod support 300 are manufactured using an integral casting process to reduce the number of connection points between the thrust rod support 300 and the first connecting beam 100. This not only significantly improves the manufacturing and assembly precision of the integrated frame crossbeam 10, ensuring the accuracy of the suspension hardpoint design dimensions and improving the structural strength of the integrated frame, but also simplifies the assembly of the thrust rod support 300 and the connecting beam during the assembly process, thereby reducing the investment and use of tooling and thus lowering production costs.

[0037] It should be noted that the first connecting beam 100 and the second connecting beam 200 are made of cast steel, thereby improving the structural strength of the integrated frame crossbeam 10 and enhancing its tensile and torsional resistance.

[0039] In this embodiment, a weight-reducing hole 110 is provided at the very center of the first connecting beam 100. This means that material at the very center of the first connecting beam 100 is removed without affecting its structural strength and stiffness. This not only significantly reduces the weight of the integrated frame crossbeam 10 but also saves material costs. Furthermore, it optimizes the stress distribution of the first connecting beam 100. By rationally arranging the weight-reducing holes 110, the load path can be altered, resulting in a more even distribution of stress across the structure, thereby preventing fatigue damage caused by localized overload. This not only extends the lifespan of the crossbeam but also improves the overall vehicle safety.

[0040] Furthermore, the first connecting beam 100 is provided with a second functional hole 120, which is used to install at least one of the brake valve body, electrical components, and wiring harness.

[0041] In the embodiment, the number of the second functional holes 120 is multiple, and the second functional holes 120 are arranged on both sides of the weight-reducing holes 110, and the multiple second functional holes 120 on both sides of the weight-reducing holes 110 are arranged in a matrix.

[0042] Further, the two wide sides of the first connecting beam 100 are provided with wire routing ports 130, and the wire routing ports 130 are used for wire harness routing.

[0043] In the embodiment, the second functional holes 120 are located between the wire routing ports 130 and the weight-reducing holes 110. By arranging the wire routing ports 130 on the two wide sides of the first connecting beam 100, the weight of the first connecting beam 100 can be further reduced, and the material cost can be further saved.

[0044] Further, the second connecting beam 200 is provided with first functional holes 210, and the first functional holes 210 are used to install at least one of brake valve bodies, electrical elements, and wire harnesses.

[0045] In the embodiment, the number of the first functional holes 210 is multiple, and the multiple first functional holes 210 are arranged in a matrix, so that the multiple first functional holes 210 can be used to install brake valve bodies, electrical elements, and also can be used to fix wire harnesses, thereby significantly improving the multifunctionality of the integrated frame cross beam 10.

[0046] Further, the second connecting beam 200 is provided with connecting holes 220, and the connecting holes 220 are located on both sides of the functional holes, and the connecting holes 220 are used to install frame connecting plates.

[0047] In the embodiment, the number of the connecting holes 220 is also multiple, and the multiple connecting holes 220 are arranged in a matrix, so that the second connecting beam 200 and the frame cross beam connecting plate can be fixedly connected by riveting at the multiple connecting holes 220.

[0048] Further, the second connecting beam 200 includes a first region 230 and two second regions 240 connected to both sides of the first region 230, the first functional holes 210 are arranged in the first region 230, and the connecting holes 220 are arranged in the two second regions 240 respectively.

[0050] Further, the width of the middle part of the second connecting beam 200 is smaller than the width of the two sides of the second connecting beam 200, that is, the two side edges of the first region 230 are in a concave arc shape, so that the width of the first region 230 gradually increases in the direction extending from the middle part to the two second regions 240.

[0051] In the embodiment, by setting the two side edges of the first region 230 in a concave arc shape, not only the structural strength of the second connecting beam 200 is enhanced, but also the weight and material of the second connecting beam 200 are reduced.
