Description

Commercial vehicle fuel tank with inner partition plate bracket device and mounting method

Technical Field

The invention belongs to the technical field of oil tank manufacturing, and particularly relates to a fuel tank of a commercial vehicle with an inner partition plate bracket device and an installation method.

Background

The inner baffle is a key component of the fuel tank of the commercial vehicle, and has the main function of improving the integral rigidity of the fuel tank and ensuring that the fuel tank does not deform excessively under the action of external force. Meanwhile, the inner partition plate can also reduce the negative effects of noise and the like caused by the impact of fuel shaking in the fuel tank on the tank body. The fuel tank body and the inner partition plate are designed and manufactured by stamping and forming a sheet metal part mostly, and the assembly and connection process between the tank body and the inner partition plate has important influence on the working reliability of the fuel tank assembly. In order to avoid damaging a fuel tank body or excessively large welding deformation, the fuel tank for the vehicle of the patent publication No. CN105416041B is characterized in that a positioning groove is formed in the side wall of the tank body, a first baffle and a second baffle are installed in the positioning groove, meanwhile, the transverse baffles are welded to realize supporting, and the transverse baffles are used for a long time, and can be separated to lose functions due to positioning looseness. The patent publication No. CN204432377U is a fuel tank inner partition board, and the fuel tank with the patent publication No. CN202294261U is a design scheme that the inner partition board is fixed in a mode that a tank body rib and a positioning arc groove on the partition board are pressed.
