Problems solved by technology

Although the invention integrates the fuel tank and the urea tank, it saves the space and difficulty of placing the urea tank. Since the urea solution corrodes common metals, common metal materials are not suitable for containing urea. Therefore, the integrated fuel tank adopts a durable The material corroded by urea, but the cost of this kind of integrated fuel tank is

Abstract

The invention provides a dual-chamber integrated pedal ladder and urea tank fuel box assembly. The dual-chamber integrated pedal ladder and urea tank fuel box assembly includes a dual-chamber pedal fuel box assembly and a urea tank assembly with same cross sections, wherein the fuel box and the urea tank are made of magnesium aluminum alloy. After the inner portion of the urea tank is treated repeatedly, the anticorrosive treatment is carried out, and the urea tank and the fuel box are welded together by the welding technology. The dual-chamber integrated pedal ladder and urea tank fuel box assembly is simple in structure, convenient to manufacture and use, low in cost and not prone to falling off, and the functions of the fuel box and the function of the urea tank are better integrated. At the same time, the occupancy of a vehicle space is reduced, a bracket and a hoop for fixing the urea tank are reduced, and people can get on and get off conveniently, so that the weight of a whole vehicle is greatly reduced, and the dual-chamber integrated pedal ladder and urea tank fuel box assembly can be applied to a variety of types of vehicle models.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an integrated fuel tank with a urea tank, and belongs to the technical field of automobile parts. Background technique [0002] In recent years, with the increasingly stringent requirements on vehicle emissions, more and more vehicles have carried out exhaust purification for exhaust emissions, and urea is one of the ways. Therefore, corresponding space and brackets need to be added on the commercial vehicle frame to install the urea tank, which increases the difficulty of assembly design. Therefore, the integrated design of the urea tank has appeared, which is combined in other components. At present, there is also an integrated urea tank fuel tank in China, which not only maintains the shape characteristics of the fuel tank in structure, but also meets the structural and functional requirements of the urea tank, reducing a set of dedicated urea tank brackets. Although the invention...
