The longitudinal beam absorbs collision energy through crushing deformation and bending deformation, and the front longitudinal beam bears 60% of the total collision energy. Although the energy absorption pressure of the rear longitudinal beam is less than that of the front longitudinal beam, it is still the main energy absorption force in the rear-end collision. Therefore, if the front and rear longitudinal beams are injured in the accident, the protective effect of these two beams on the cockpit will be greatly reduced in the future driving process.
Accident vehicles refer to vehicles that have been severely hit, soaked in water, burned, etc. But even after the repair, there are still security risks. These vehicles are collectively referred to as accident vehicles. The unified feature of this kind of vehicle is that when the vehicle collides or is damaged, it will hurt the components such as the beam and the frame, and it needs to be cut and welded before it can be repaired.
Strictly speaking, as long as there has been an accident, it is an accident car. According to the size of the accident, vehicles with major accidents can be distinguished from vehicles with minor accidents. Generally speaking, as long as the damaged parts can be replaced, they are all minor accidents. For example, if the front bumper is damaged, the headlights are damaged, and the front fender is damaged, the vehicle will depreciate.
If the longitudinal beam, chassis and ABC column of the car cannot be replaced, they can only be repaired by shaping, cutting and welding. This situation is a serious accident car. If it is an accident car, the strength will drop a lot after repair, and this kind of used car depreciates more than the accident car.
