[0003] The cab is a crucial part of a truck, and the functional requirements of the front underbody suspension are becoming increasingly clear. The overall trend towards lightweight cabs is driving the development of lightweight cab suspension systems as well. The primary function of the front underbody suspension in the suspension system is to support cab tilting and limit its movement, while also connecting it to the chassis.

[0004] In the existing technology, the cab under-support is made of ductile iron casting, which is relatively heavy. This results in an overall heavy weight of the cab suspension system, which is not conducive to reducing the energy consumption ratio per unit mileage of the whole vehicle and the underutilization of materials. In addition, the cost of ductile iron cab under-support is too high, and there are many internal defects and low production efficiency. Utility Model Content

[0025] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0026] See Figure 1 and Figure 2 As shown in the figure, a cab suspension lower support 100 is shown. The maximum projection surface of the cab front suspension lower support is an h-shaped projection surface, i.e. Figure 1 and Figure 2 The projected area shown is formed by connecting the interior of the h-shaped projection surface with straight reinforcing ribs 110 and cylindrical reinforcing ribs 120, and connecting the sides 130 and 140 of the h-shaped projection surface with long waist-shaped reinforcing ribs 150 and cylindrical reinforcing ribs 120.

[0027] Specifically, the lower front suspension support of the cab in this invention is made of A356 aluminum alloy using a liquid forging process. Using A356 aluminum alloy instead of ductile iron or steel achieves lightweighting of the lower front suspension support, reducing the overall weight of the suspension system, lowering costs, and reducing the vehicle's energy consumption per unit mileage. Liquid forging is a novel casting process with advantages such as high quality, high efficiency, energy saving, low consumption, and wide adaptability. This process utilizes external force to solidify and rheologically transform the molten metal in a high-strength mold, thereby forcibly eliminating shrinkage cavities or porosity defects caused by solidification shrinkage, and even inducing plastic deformation. This invention employs this advanced casting process, resulting in a significant improvement in its quality and performance.

[0028] See Figure 3 and Figure 4 The figure shows a device for manufacturing a lower front suspension support for a driver's cab, including a material stalk 200 and a mold body 300 fixed to the top of the material stalk 200 for the lower front suspension support 100 of the driver's cab. The entire mold body 300 is made of high-strength metal, allowing liquid metal to fill the interior of the mold body 300 under pressure, ensuring a high surface quality of the lower front suspension support 100 of the driver's cab.

[0029] The material shank 200 is shell-shaped and has a cylindrical structure. The material shank 200 and the flow channel 210 (the aforementioned first flow channel) are designed as a classic thick three-pronged structure. The thick material shank 200 can compensate for defects caused by shrinkage inside the product, and the aluminum liquid can flow into the mold better, which is convenient for molding.

[0030] A grouting port 220 is provided at the end of the material stalk portion 200. Both the material stalk portion 200 and the interior of the mold body 300 are cavities. The cavities 310 within the material stalk portion 200 and the mold body 300 are connected through a flow channel 210. The flow channel 210 includes an injection end and an output end. The injection end is connected to the cavity of the material stalk portion 200, and the output end is connected to the cavity 310 of the mold body 300. The output end of the flow channel 210 is a cylindrical output end.

[0031] There are two cavities 310 inside the mold body 300, and there are also two output ends of the flow channel 210. The two cavities 310 inside the mold body 300 are located on the top side of the two output ends of the flow channel 210.

[0032] At least one slag pack 320 and at least one venting groove 330 are provided on the parting surface of the mold body 300 opposite to the material shank 200. At least one slag pack 340 and at least one venting groove 350 are provided on the mold body 300 opposite to the material shank 200. The function of the slag packs 320 and 340 is to facilitate the better removal of air at the parting surface of the mold body 300 and residual impurities during production and cleaning. At the same time, it can balance the temperature of the mold, so as not to have serious flash and burrs on the subsequent products, and reduce internal defects of the products.

[0033] The interiors of slag bags 320 and 340 and venting channels 330 and 350 are all cavities. The cavities in slag bags 320 and 340 are connected to the cavity 310 in the mold body 300, and are also connected to the venting channels 330 and 350 through the cavities in flow channels 360 and 370.

[0034] The cavities of slag bags 320 and 340 form a quadrilateral structure with the cavity 310 inside the mold body 300. A recovery bag 380 is provided inside the cavity 310 of the mold body 300, and the recovery bag 380 is connected to the venting groove 330 through the flow channel 390; the cross-sections of the flow channels 210, 360, 370, and 390 are rectangular.

[0035] How to use the cab front suspension lower support manufacturing equipment of this utility model:

[0036] During operation, molten aluminum is poured into the grouting port 220 of the slurry shank 200. The molten aluminum is then filled through a cavity 310 within the mold body 300 that matches the shape of the lower front suspension support 100 of the cab, forming the lower front suspension support 100 of the cab. Slag pockets 320 and 330 are created at the front end and confluence of the molten aluminum to collect cold materials. When the molten aluminum is filled to 90%, a pressure of 80-100 MPa is applied, allowing the molten aluminum to solidify sequentially under high pressure, thus obtaining the high-performance lower front suspension support 100 of the cab.
