You mean the crash beam? The beam on the bumper? In that case, you'd better buy a new one. Once this kind of anti-collision beam is hit, it will lose its great protection. After the repairman's shaping, the surface can be restored, but after a little collision, the deformation will be serious, and it will not protect the engine, transmission and fuel tank. The front cross member is the first cross member behind the front bumper. The front beam of the car is the front bumper of the car. As you can imagine, there is a wall in front of the car, and the car flies gently. The first thing that hit the wall was the front bumper, which is what you called the front crossbar. This part is basically plastic, only metal is used in the cart, but after engineering analysis and design, its structure is affected. Although it is plastic, it is very strong. Slightly overweight can be repaired, and severely overweight must be replaced. Automobile crossbeams have three main functions: 1. When a vehicle collides, the front bumper anti-collision beam distributes the energy generated by any form of offset and frontal collision on the two energy-absorbing brackets as evenly as possible, absorbs the energy uniformly to the maximum extent, and transmits the impact force to other energy-absorbing components. 2. When the automobile rear-end collides at low speed on urban roads, the front bumper anti-collision beam plays a certain role in protecting the fender, radiator, hood, lights and other components. 3. The rear bumper anti-collision beam can reduce the damage of luggage compartment, tailgate and taillight group.
