1. The longitudinal beam can't completely recover its shape even after correction, and abnormal sound or * * * vibration is easy to appear during driving;
2. The rigidity of the car body is affected. After all, the metal will bend and wrinkle after the girder is deformed. Even after repair, the strength of this folding is not as high as that of the original factory, and the safety performance of the car will be affected to some extent;
3. After the girder hits, it is an accident car. A big accident car will greatly affect the price of used cars. When it is sold as a used car, the price will be greatly reduced.
If the girder is replaced, it will not affect the annual inspection. As long as the girder is properly installed, there is basically no problem without affecting the operation of the car. However, if the whole frame is replaced, you need to go to the vehicle management office to re-enter the frame number, otherwise you will not pass the annual inspection. The materials of automobile crossbeams are basically high-strength steel plates, which are mainly riveted to connect crossbeams and longitudinal beams to form rigid structures. Only in this way can they have enough strength and rigidity to bear the load of the car and the impact from the wheels. As long as there is no accident, maintenance is generally not needed.
