Lightweight all-aluminum alloy powder material transport semi-trailer

Abstract

The application discloses a lightweight all-aluminum alloy powder and particle material transportation semitrailer, which comprises a tank assembly which is made of an all-aluminum alloy part; the bottom part of the tank assembly is fixedly connected with a frame assembly; the frame assembly is made of the all-aluminum alloy part; two heaviest components of the semitrailer are the tank assembly and the frame assembly, and account for about 90 percent of total weight; after the all-aluminum alloy parts are adopted by both the tank assembly and the frame assembly, the total weight is reduced by one half in comparison with the weight of an all-stainless steel semitrailer in the prior art, and is reduced by 1 / 3 in comparison with the weight of a semi-stainless steel and semi-aluminum alloy semitrailer; as a body is lighter, the tank can be made bigger after the own weight of the semitrailer is reduced, and more materials can be loaded by the semitrailer at one time; the tank assembly and the frame assembly are respectively made of the all-aluminum alloy part, and the tank assembly can be directly welded to the frame assembly, so the problems that a subframe needs to be designed and the tank assembly and the frame assembly can be connected only by a bolt as two kinds of materials are adopted are avoided, and a body structure is simple, manufacturing processes are simplified, and the total weight is lighter.

Description

technical field [0001] The application belongs to the technical field of special vehicles, and specifically relates to a lightweight all-aluminum alloy powder material transport semi-trailer. Background technique [0002] The powder material semi-trailer can be used in the transportation of bulk powder materials in industry, agriculture, and construction, such as the transportation of bulk cement, fly ash, talc powder, powder feed, and lime powder materials, ending the need for packaging of bulk powder materials The transportation history of loading and unloading, and there is no pollution and no noise during the loading and unloading of bulk powder materials. [0003] At present, there are two main types of semi-trailers for powder materials: all-steel, and its structure includes tank body assembly, frame assembly, piping system, tank roof platform, tank rear ladder, side guardrails, fenders, rear insurance Bar, spare tire assembly and tool box, under the same load conditi...

AI Technical Summary

Problems solved by technology

[0004] Half-aluminum and half-steel, its structure includes tank body assembly, piping system, tank top walking platform, tank rear ladder, side guardrails, fenders, sub-frame and tool box are all made of aluminum. The part with heavy force is made of steel, and the half frame and spare tire are made of steel. Under the condition of the same load as stipulated by road traffic regulations, the weight of the whole vehicle is slightly lighter than that of the all-steel model, and the tank volume It can be slightly larger, and the negative fuel consumption caused by the self-weight of the whole vehicle is slightly less during transportation, and the loaded materials are slightly larger. However, due to the different materials of steel and aluminum, they cannot be connected by welding, so a sub-frame must be installed to place the tank It is bolted to the frame assembly, so the structure is more complicated than that of all steel

[0005] If all aluminum alloy parts are used, especially the frame assembly and the tank body assembly are made of aluminum alloy parts, although the frame assembly and the tank body assembly can be welded, the total weight of the car body is also lighter, but because the tank body Due to the structural limitations of the assembly and the frame assembly, the strength of the connecting parts is difficult to meet the requirements, and it is easy to cause problems such as fracture of the stressed parts under load
