Beschreibung
Zusammenfassung:	Disclosed is a urea tank and fuel tank assembly, which belongs to the field of automobile parts. The urea tank and fuel tank assembly includes a shell, wherein the shell includes an upper shell, a middle shell and a lower shell, the upper shell, the middle shell and the lower shell are welded separately to form a cavity including a fuel cavity. The urea tank and fuel tank assembly is welded after injection molding, so that not only is the shell uniform in wall thickness and high in mechanical strength, but also the welding stress is dispersed to the upper and lower ends of the shell by setting that the upper shell, the middle shell and the lower shell are welded separately, on the one hand, the stress concentration of the welded part of the shell is reduced and the cracking of the welded part is avoided; on the other hand, because the middle area of the shell bears the maximum flow impact force caused by the shaking of liquid such as fuel, avoiding setting welded joints in the middle of the shell can not only improve the overall strength of the shell, but also avoid the cracking of the welded part of the shell due to suffering from the impact force, and improve the service life of the fuel tank.
