Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of automobile parts, and particularly relates to an anticorrosion oil tank bracket forge piece. BACKGROUND

[0002] The oil tank bracket forge piece is a mechanical component processed through a forging process and is mainly used for supporting and fixing an oil tank. It is usually made of metal materials with high strength and toughness, such as carbon steel, alloy steel, etc. After the forging process, the internal organization of the metal material is refined and densified, so that the oil tank bracket forge piece has good mechanical properties and can withstand the weight of the oil tank and various vibrations and impact loads generated during vehicle driving, ensuring the stability and safety of the oil tank during vehicle operation. At the same time, various mounting holes and connecting structures are generally designed on the oil tank bracket forge piece to facilitate reliable connection with the chassis or other components of the vehicle.

[0003] The oil tank bracket forge piece is usually located at the bottom of the vehicle and is exposed to the external environment for a long time, which is easily eroded by rainwater, snowwater, dust, and various chemicals on the road. Its surface will gradually rust and corrode, resulting in a decrease in material strength and a weakening of the structure. This will affect the supporting capacity of the bracket for the oil tank, and during vehicle driving, the oil tank may deform or break due to the inability to withstand the weight and vibrations of the oil tank, thereby causing the oil tank to fall and other serious safety accidents.

[0004] The existing oil tank bracket forge piece generally uses bolts and other components to fix the supported oil tank on the vehicle frame from below. Although this traditional fixing method can achieve stable connection of the oil tank and the vehicle frame in a static state, it is difficult to withstand the complex and variable working conditions during vehicle driving. In actual operation, the vehicle inevitably encounters road surface undulations, deceleration belt impacts, and vibrations generated by engine operation. These continuous and irregular external forces will cause the oil tank fixed by the oil tank bracket forge piece to be frequently stressed. Over time, even if the bolts are in a tightened state, the oil tank will still have slight displacement and shaking on the bracket. With the passage of time, these seemingly small displacements and shaking will continuously accumulate, causing the connecting components between the oil tank and the bracket to continuously bear additional shear force and friction force, thereby causing problems such as loose bolts and bracket surface wear. This not only affects the stability of the oil tank position and reduces the reliability of the fuel system, but also accelerates the fatigue damage of the oil tank bracket forge piece, significantly shortens its service life, and even may cause fuel line pulling and rupture due to oil tank displacement, bringing safety hazards such as fuel leakage.

In actual operation, the vehicle inevitably encounters the road surface undulation, deceleration zone impact and the vibration produced by engine operation, and these continuous and irregular external force effect will make the oil tank that is fixed by the oil tank bracket forge piece frequently stressed. After a long time, even if the bolt is in the state of tightening, the oil tank still can appear the slight displacement and the shaking on the bracket. With the time elapsing, these seemingly slight displacement and shaking will continuously accumulate, cause the connecting component between the oil tank and the bracket to continuously bear the additional shear force and friction, and then cause the problems such as bolt loosening, bracket surface wear. This not only influences the stability of oil tank position, reduces the reliability of fuel system, but also accelerates the fatigue damage of oil tank bracket forge piece, greatly shortens its service life, and even possibly causes the fuel pipeline to be pulled and broken due to the oil tank displacement, brings the problems such as fuel leakage and other safety hidden troubles.
