[0045] See Figure 1 - Figure 2, a front panel air spring lower bracket 10 provided by an embodiment of the present application includes: a bracket body 1, and the bracket body 1 is connected to a vehicle body 20; a first connecting portion 2, the first connecting portion 2 is connected above the bracket body 1, and a vehicle brake pipeline bracket 30 is connected to the first connecting portion 2; a second connecting portion 3, the second connecting portion 3 is vertically connected above one side of the first connecting portion 2, and a lower fulcrum of an air spring 40 is connected to the second connecting portion 3; a third connecting portion 4, the third connecting portion 4 is connected to one side of the second connecting portion 3 and is connected to the vehicle body 20.

[0046] This embodiment is designed according to the requirements of the overall vehicle front panel structure, production, assembly, and pipeline routing. The bracket body 1 is closely and firmly connected to the vehicle body 20. The upper and lower two mounting positions of the third connecting portion 4 and the bracket body 1 cooperate to integrally mount the bracket on the vehicle body, with firm installation and meeting the reliability requirements. The first connecting portion 2 is used for assembling the vehicle brake pipeline bracket 30, and the second connecting portion 3 is used for assembling the lower fulcrum of the air spring 40. The second connecting portion 3 is arranged on one side of the first connecting portion 2 to prevent interference with the assembly of the vehicle brake pipeline bracket 30 on the first connecting portion 2.

[0047] The front panel air spring lower bracket described in this embodiment, through integrated design, can effectively meet the simultaneous assembly of the lower fulcrum of the air spring and the vehicle brake pipeline bracket, meet the requirements of routing the cab front pipe harness, improve the assembly efficiency, save the production beat, and meet the reliability and appearance quality requirements. While meeting the use functions, the structure is simple and the operation and installation are convenient.

[0048] Further, it further includes a first connecting plate 5 and a second connecting plate 6; both ends of the bracket body 1 are respectively connected to the front end of the first connecting plate 5 and the front end of the second connecting plate 6; both ends of the first connecting portion 2 are respectively connected to the upper end of the first connecting plate 5 and the upper end of the second connecting plate 6; the bracket body 1, the first connecting portion 2, the first connecting plate 5, and the second connecting plate 6 are connected into a "door" - shaped structure; the second connecting portion 3 is vertically connected to the connection portion between the first connecting portion 2 and the second connecting plate 6. The "door" - shaped structure strengthens the connection strength of the first connecting portion 2 and makes the assembly of the vehicle brake pipeline bracket 30 more reliable.

[0049] In this embodiment, the lower end of the second connecting portion 3 is connected to the connection portion between the first connecting portion 2 and the second connecting plate 6, the upper front side is connected to the third connecting portion 4, the middle and lower front side is set to a shape that fits the vehicle body 20 profile, and the upper rear side is connected to the lower fulcrum of the air spring 40.

[0050] Optionally, the lower ends of both the first connecting plate 5 and the second connecting plate 6 are set to a structure that is concave inward to better fit the overall vehicle front panel structure.

[0051] Further, the structure of the front bulkhead gas spring lower bracket is integrally formed. The basic thickness of the bracket is 6 mm, the minimum fillet is R = 0.5 mm, and the draft angle is not more than 1°. It is formed by die casting, which can effectively solve the technical problem of difficult forming of sheet metal stamping parts. Its die can achieve a multi-cavity structure, improve production efficiency, and ensure production and vehicle loading.

[0052] Further, the structure of the front bulkhead gas spring lower bracket is made of cast aluminum material. Since the cast aluminum material meets the anti-corrosion grade requirements, there is no need for surface painting treatment, reducing the process steps and saving costs.

The second connection hole A11-1 is circular, and the second connection hole B11-2 is elliptical. The two second connection holes 11 cooperate with the first connection hole 41 to install the bracket on the vehicle body 20 through three fixed points, making the bracket installation more reliable and firm.

[0056] Further, a third connection hole 31 is opened at the upper end of the second connection part 3, and the lower fulcrum of the gas spring 40 is connected in the third connection hole 31.

[0057] Further, a fixing hole 21 and a through hole 22 are opened on the first connection part 2; the lower end of the vehicle brake line bracket 30 passes through the through hole 22 and is fixed to the first connection part 2 through the fixing hole 21. The diameter of the through hole 22 is larger than the outer diameter of the vehicle brake line bracket 30 to ensure that the line bracket can pass smoothly from top to bottom during installation. After the lower end of the vehicle brake line bracket 30 passes through the through hole 22, bolts and nuts are used to fix the lower end of the vehicle brake line bracket to the first connection part 2 through the fixing hole 21.

[0058] The assembly process of the front bulkhead gas spring lower bracket described in this embodiment is as follows:

[0059] The bracket body 1 and the third connecting part 4 are respectively installed on the vehicle body through the second connecting hole 11 and the first connecting hole 41. The lower end of the vehicle brake pipe bracket 30 passes through the through hole 22 and is fixed on the first connecting part 2 through the fixing hole 21. Finally, the lower fulcrum of the gas spring 40 is connected in the third connecting hole 31, and the assembly of the entire front panel gas spring lower bracket is completed.
