[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0022] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Example

[0024] Please see Figures 1 to 4 As shown, this embodiment provides a commercial vehicle balance beam integrated device 1, including a balance beam casting 11. The balance beam casting 11 includes an integrally connected crossbeam 12, a bracket 13, a first connecting plate 14, and a second connecting plate 15. The crossbeam 12 is hollow. The first connecting plate 14 is located at the bottom of the crossbeam 12 and is used to fix and connect the balance shaft. The second connecting plate 15 is located at the end of the crossbeam 12 and is used to fix and connect the vehicle frame. The bracket 13 is located on the circumferential surface of the crossbeam 12 and is used to connect the thrust rod assembly.

[0025] The commercial vehicle balance beam integration device 1 integrates the crossbeam 12, bracket 13, first connecting plate 14 and second connecting plate 15 by integrally casting the balance beam casting 11, thereby improving the overall strength of the balance beam casting 11. The balance beam casting 11 reduces the weight of the balance beam casting 11 by setting a hollow crossbeam 12. Thus, the commercial vehicle balance beam integration device 1 reduces the weight of the balance beam while meeting the strength requirements of the balance beam.

[0026] In this embodiment, the cross-sectional shape of the crossbeam 12 is square. The crossbeam 12 is cast with a hollow structure to reduce the weight of the commercial vehicle balance beam integration device 1 and reduce manufacturing costs. The crossbeam 12, bracket 13, first connecting plate 14 and second connecting plate 15 are integrally cast to reduce the disassembly and assembly of parts, thereby improving the overall strength of the commercial vehicle balance beam integration device 1. At the same time, it reduces the assembly work of parts to improve work efficiency and reduce manufacturing costs.

[0027] In one possible implementation, the first connecting plate 14 is provided with a first plate 141, a second plate 142, a third plate 143 and a fourth plate 144. The first plate 141 and the second plate 142 are provided on one side of the crossbeam 12, and the third plate 143 and the fourth plate 144 are provided on the other side. The first plate 141, the second plate 142, the third plate 143 and the fourth plate 144 are respectively fixedly connected to the balance shaft.

[0028] In this embodiment, the first connecting plate 14 is fixedly connected to the balance shaft via a first plate 141, a second plate 142, a third plate 143, and a fourth plate 144, respectively, to improve the stability and connection strength of the connection between the first connecting plate 14 and the balance shaft. One side of the crossbeam 12 is connected to the first plate 141 and the second plate 142, and the other side is connected to the third plate 143 and the fourth plate 144. This arrangement helps to improve the structural strength of the crossbeam 12, increasing its strength while reducing its weight.

[0029] In one possible implementation, the support 13 includes a first frame 131 and a second frame 132. The first frame 131 is disposed between the first plate 141 and the second plate 142 and is used to connect the first thrust rod of the thrust rod assembly. The second frame 132 is disposed between the third plate 143 and the fourth plate 144 and is used to connect the second thrust rod of the thrust rod assembly.

[0030] In one possible implementation, the first plate 141 and the second plate 142 are respectively connected to the crossbeam 12 to strengthen the crossbeam 12. The first frame 131 is disposed between the first plate 141 and the second plate 142 and is connected to the crossbeam 12, thereby improving the stability of the connection between the first frame 131 and the crossbeam 12 and reducing the deformation of the crossbeam 12 caused by the force on the first frame 131.

[0031] In one possible implementation, the first connecting plate 14 has a first connecting hole 145, and the first connecting plate 14 is fixedly connected to the balance shaft through the first connecting hole 145.

[0032] In this embodiment, the first connecting plate 14 and the balance shaft are connected by mounting bolts in the first connecting hole 145, thereby fixing the commercial vehicle balance beam integration device 1 to the balance shaft.

[0033] In one possible implementation, the crossbeam 12 includes a beam portion 121 and a protrusion 122. The protrusion 122 is disposed on the circumferential surface of the beam portion 121, with one end of the protrusion 122 connected to the beam portion 121 and the other end connected to the first connecting plate 14.

[0034] In this embodiment, the protrusion 122 brings the first connecting plate 14 close to the balance shaft, which is beneficial for the connection between the first connecting plate 14 and the balance shaft.

[0035] In one possible implementation, the protrusion 122 extends downward from the beam portion 121 along the vertical direction 16 so that the first connecting plate 14 fits against the surface of the balance shaft.

[0036] In this embodiment, the protrusion 122 makes the surface of the first connecting plate 14 fit with the balance shaft, thereby improving the positioning and fixing accuracy of the first connecting plate 14 and the balance shaft, which is beneficial to the fixed connection between the first connecting plate 14 and the balance shaft.

[0037] In one possible implementation, there are two second connecting plates 15. One end of the crossbeam 12 has a first opening 123 and the other end has a second opening 124. The first opening 123 and the second opening 124 are connected, and the periphery of the first opening 123 and the periphery of the second opening 124 are respectively connected to the second connecting plate 15.

[0038] In one possible implementation, the second connecting plate 15 has a second connecting hole 151, and the second connecting plate 15 is fixedly connected to the frame through the second connecting hole 151.

[0039] In this embodiment, the second connecting plate 15 is connected to the vehicle frame by mounting bolts in the second connecting hole 151, thereby fixing the commercial vehicle balance beam integration device 1 to the vehicle frame.

[0040] In summary, the commercial vehicle balance beam integrated device 1 integrates the crossbeam 12, bracket 13, first connecting plate 14 and second connecting plate 15 into a single casting through the balance beam casting 11, thereby improving the overall strength of the balance beam casting 11. The balance beam casting 11 reduces its weight by incorporating a hollow crossbeam 12. Thus, the commercial vehicle balance beam integrated device 1 reduces the weight of the balance beam while meeting the strength requirements of the balance beam.
