What does a large rear bottom spoiler of a car mean
The rear bottom deflector of a car is an airflow control device installed at the bottom of the rear part of the vehicle body. Its main function is to reduce air resistance and enhance driving stability by guiding the flow of air, and it also has a protective function.
Core function
Youdaoplaceholder0 reduce air resistance
The deflector plate optimizes the airflow path under the vehicle, reduces the wind resistance coefficient, making it easier for the vehicle to travel at high speeds and also lowers wind noise.
Youdaoplaceholder0 balance lift
When driving at high speed, the lift force generated by the airflow under the vehicle may cause the vehicle to float. The deflector plates enhance the vehicle's stability by guiding the airflow downward.
Youdaoplaceholder0 protective effect
Some of the deflector plates are made of resin, which can buffer minor collisions and protect the engine compartment and chassis components from scratches and damage.
Installation Precautions
Youdaoplaceholder0 Material selection : It is recommended to use resin or plastic materials to avoid the impact of metal materials on the safety of engine sinking
Youdaoplaceholder0 Installation method : The number of screws should be controlled at 4 to 8 (M6 or less) to avoid excessive reinforcement and potential safety hazards
Youdaoplaceholder0 applicable scenarios : No additional installation is required on daily urban roads. It can enhance the protection effect in complex road conditions (such as muddy and bumpy) .
The main functions of the rear bottom deflector plate of a car are reflected in the following aspects:
Reduce air resistance and lift
The deflector plate optimizes the airflow path at the bottom of the vehicle body, reduces the air pressure under the vehicle, decreases the air lift caused by the difference in vehicle body shape during high-speed driving, lowers air resistance, and improves fuel economy and driving stability.
Prevent the rear wheels from floating
The downforce generated by the deflector can enhance the friction between the tires and the ground, prevent the rear wheels from floating due to lift during high-speed driving, and improve handling and braking safety.
Optimize airflow guidance
Sort out the airflow at the rear of the vehicle, reduce vortices and turbulence, keep the rear of the vehicle clean and lower air resistance, and further improve driving efficiency.
Protective function
In minor collisions, the deflector can absorb part of the impact force and reduce damage to the vehicle body.
The rear bottom deflector plate of the car must be replaced when it is severely damaged. The degree of damage to the deflector plate directly affects the stability and safety of vehicle driving. Specific handling should be carried out based on the extent of the damage
Situations where replacement is necessary
The deflector plate needs to be replaced immediately when the following situations occur:
Youdaoplaceholder0 Structural damage : Cracks larger than 5 centimeters, fractures or loose connection parts more than 5 millimeters (such as fingers can be inserted) appear;
Youdaoplaceholder0 Function failure : Large-scale cracking leads to a decrease in vehicle stability during high-speed driving (such as a floating rear end) and an abnormal increase in fuel consumption (measured fuel consumption rises by 1.5 liters per 100 kilometers).
The situation where replacement is temporarily suspended can be repaired
If the following conditions are met, replacement may be temporarily omitted:
Youdaoplaceholder0 Minor damage : surface scratches, paint peeling and crack length ≤1 cm;
Youdaoplaceholder0 application scenario : Driving at low speed only on unpaved roads. However, it is necessary to check the expansion of cracks every month to avoid delays that could lead to increased maintenance costs.
Suggestions for Supporting Disposal
Youdaoplaceholder0 Self-inspection method : Observe whether the cracks are spreading in a spider web pattern, gently shake to detect the degree of loosening, and listen for abnormal air leakage sounds at a speed of 80 kilometers per hour.
Youdaoplaceholder0 Cost control : Choose a counterfeit PP/ABS material deflector plate with a thickness of ≥ 3mm (counterfeit parts for Wuling models cost about 80 yuan), and self-spray painting repair can save painting costs.
The design life of the deflector plate exceeds three years. When maintaining it, the principle of "disposal as needed" should be followed. Scrap parts should be transformed into tool bases and other resource reuse methods to avoid unnecessary expenses.
