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 too high, which is about 2 times higher than the total price of the common aluminum alloy fuel tank urea tank; or the weight of the tank is too large, which is 2 times the total weight of the split aluminum alloy fuel tank above
Therefore, the current technical solution is fundamentally unable to balance the cost and lightweight requirements of the integrated fuel tank.

The invention provides a single-chamber integrated boarding ladder and urea vessel fuel tank assembly, comprising a pedal fuel tank assembly and a urea vessel assembly with the same cross-section. Thefuel tank and the urea vessel are both made of magnesium aluminum alloy. The inside of the urea vessel is subjected to multiple times of treatments, anti-corrosion treatment is then conducted, and the urea vessel is welded to the fuel tank through welding. The structure is simple, and the functions of the fuel tank and the urea vessel are well integrated, thus manufacturing and use are convenient, the cost is low, and falling off does not easily happen; and the occupancy rate of the vehicle space is reduced, a bracket and a band for fixing the urea vessel are reduced, and the personnel can get on and off the vehicle conveniently, the weight of the vehicle can be greatly reduced, and the single-chamber integrated boarding ladder and urea vessel fuel tank assembly can be applied to different models of vehicles.
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...
