The invention belongs to the technical field of automobile fuel tank manufacturing, and discloses a reinforcing device of an automobile fuel tank and a fuel tank of a large and medium-sized fuel vehicle. The reinforcing device of the automobile fuel tank comprises a fuel tank body, and a first reinforcing device and/or a second reinforcing device are/is installed in the fuel tank body in a penetrating mode. The tail ends of the first reinforcing devices are welded to oil tank plugging plates on the two sides of the oil tank body. At least one oil tank oil baffle plate is arranged in the middle of the first reinforcing device in a penetrating mode. Inertial thrust formed on fuel oil in the fuel tank body when the vehicle speed is unstable is transmitted and dispersed through the first reinforcing device, the fuel tank oil baffle plate, the fuel tank plugging plate and the second reinforcing device which are connected with one another. The problems that metal fatigue occurs at a welding point of the oil baffle plate of the oil tank, cracks and oil leakage occur, and metal powder is generated due to abrasion caused by open welding sliding of an internal assembly, so that an electronic fuel injection head of an automobile engine is blocked and scrapped are solved. The stressed stress is differentiated, so that the service life of the whole part is prolonged by several times.

    本发明属于汽车油箱制造技术领域,公开了一种汽车油箱的加固装置及大中型燃油车辆油箱。汽车油箱的加固装置,包括油箱主体,所述油箱主体内部贯通安装有第一加固装置和/或第二加固装置;所述第一加固装置的末端与油箱主体两侧的油箱封堵板焊接安装;所述第一加固装置的中部贯穿设置有至少一个油箱挡油板;通过相互连接的第一加固装置、油箱挡油板、油箱封堵板以及第二加固装置将车速不稳定时对油箱主体内部的燃油形成的惯性推力传输分散。解决了油箱挡油板焊接点出现金属疲劳出现裂纹漏油现象,和内部组合件开焊滑动出现磨损产生金属粉末,导致汽车发动机电喷油头堵塞报废的问题。本发明将被受的应力分化,使整体部件的使用寿命增加了几倍。
