Abstract

The invention discloses an integrated fuel tank and its manufacturing process. The integrated fuel tank comprises an upper shell, a lower shell, a first reinforcing plate and a second reinforcing plate. The upper shell and the lower shell are assembled into a box by welding, and the cavity in the box is divided into a urea chamber and a fuel chamber along the long axis; the first reinforcing plate is arranged on the inner surface of the welding edge of the upper shell; the second Two reinforcing plates are arranged on the inner surface of the welding edge of the lower shell, one of the first reinforcing plate or the second reinforcing plate is formed with an insertion slot along the box assembly direction, the other of the first reinforcing plate or the second reinforcing plate One is provided with a plug-in part capable of being inserted into the plug-in slot.

Description

technical field [0001] The invention belongs to the field of auto parts, and in particular relates to an integrated fuel tank. Background technique [0002] With the rapid development of the automobile industry and the improvement of automobile environmental protection requirements, automobile fuel tanks and automobile urea tanks are important safety and regulatory parts in automobile parts, and their structure optimization and performance improvement have become the major automobile manufacturers. solved problem. When the fuel tank and the urea tank are arranged separately on the vehicle body, it takes up a lot of space and is not easy to install. Therefore, there is an integrated fuel tank that cancels the separate urea tank and integrates it with the fuel tank. [0003] Fuel tanks are generally made of metal materials such as cold-rolled steel plates, which have the advantages of cheap price, easy molding, and relatively low mold cost, but their weight and volume are lar...
