Mudguard, also known as mudguard, is the outer panel of the car body, covering the wheels. According to the installation position, it is divided into front fender and rear fender. Its function is to use fluid mechanics to reduce the drag coefficient and make the car run more smoothly. The front fender is mounted on the front wheel. Because the front wheel has steering function, it is necessary to ensure the maximum limit space when the front wheel rotates. Therefore, the designer will verify the design size of the fender with the wheel jump diagram according to the selected tire model size. There is no wheel rubbing problem on the rear fender, but due to aerodynamic considerations, the rear fender is slightly arched outward.
An accident vehicle meets one of the following conditions: 1, a vehicle that has been damaged by collision in the engine compartment and cockpit; 2. The impact damage of the rear fender exceeds one third of the vehicle; 3. The longitudinal beam has vehicles that are welded, cut, reshaped and deformed; 4. The shock absorber seat has welded, cut, reshaped and deformed vehicles; 5.ABC column has welded, cut, reshaped and deformed vehicles; 6. Vehicles with airbags ejected due to impact. 7. Vehicles with other non-removable parts that are severely welded, cut, reshaped and deformed; 8. Vehicles whose bodies are soaked in water for more than half of their bodies, or vehicles with accumulated water entering the cockpit; 9. The car body was burned by fire for more than 0.5 square meters. After repair, there are still potential safety hazards. (Photo/Text/Photo: Pacific Auto Network Wu Jiahong)
