The role of the deflector.
01 Stable
The deflector plays a key stabilizing role in automobile design. Its main purpose is to reduce the lift generated by the car when driving at high speed, so as to avoid the adhesion between the wheel and the ground is reduced, resulting in unstable car driving. When the car reaches a certain speed, the lift may exceed the weight of the car, causing the car to float. To counter this lift, the deflector is designed to create a downward pressure under the car, thereby increasing the adhesion of the wheels to the ground and improving the car's driving stability. In addition, the tail (which is also a type of deflector) creates downforce at high speeds, further reducing lift but potentially increasing the drag coefficient.
02 Dredge air flow
The main function of the deflector is to divert the air flow. In the process of spraying, by adjusting the Angle of the deflector, the wind direction can be controlled, so that the drug can be accurately sprayed to the designated area. In addition, the baffle can also reduce the speed of the dust-containing air flow and distribute it evenly under the action of the secondary diversion, so as to ensure the effective purification of the gas.
03 Disrupt and reduce air flow into the underside of the car
The main function of the deflector is to disturb and reduce the air flow into the bottom of the car, thus reducing the lift force generated by the air flow on the car when driving at high speed. When the car is traveling at high speeds, the instability of the bottom air flow causes an increase in lift, which can affect the stability and handling of the car. The design of the deflector can effectively disrupt and reduce this unstable air flow, thereby reducing the lift and improving the driving stability of the car.
04 Reduced air resistance
The main function of the deflector is to reduce air resistance. On vehicles, aircraft, or other objects moving at high speeds, air resistance consumes a lot of energy, which affects performance. The design of the deflector can effectively change the direction and speed of the air flow, so that it flows more smoothly through the object, thereby reducing air resistance. This not only improves energy efficiency, but also improves the overall performance of the object.
05 Purify air flow from under the chassis
The deflector serves to purify the air flow from under the chassis in vehicle design. The main purpose of this design is to reduce air pollution such as dust, mud and other impurities under the chassis, thus ensuring that the vehicle does not inhale these pollutants while driving. By effectively diverting and filtering these air currents, the deflector helps to improve the driving performance and ride comfort of the vehicle, while also helping to extend the service life of the vehicle.
The physical principle of the action of the deflector
The main role of the deflector is to reduce the lift generated by the vehicle at high speed through the principle of aerodynamics, thereby improving the stability and driving safety of the vehicle. This function is mainly achieved through the following physical principles:
Application of the Bernoulli principle: The design of the deflector uses the Bernoulli principle, that is, the speed of air flow is inversely proportional to the pressure. When the vehicle is traveling at high speed, the deflector reduces the air pressure under the car by changing the air velocity and pressure distribution under the car, thus reducing the lift force caused by the air pressure difference of the vehicle.
Increased downward pressure: The design of the deflector also includes the use of protruding objects at the bottom and rear of the vehicle. These designs can effectively direct the air flow downward, increase the pressure of the vehicle on the ground, improve the grip, and thus enhance the driving stability of the vehicle.
Reduce eddy current and resistance: the baffle can not only reduce the eddy current generated by the shape of the vehicle, but also reduce the total amount of air entering the bottom of the vehicle, further reducing the lift and resistance under the car, thereby improving the safety of driving.
The application of these physical principles makes the deflector play an important role in automobile design, especially in improving vehicle stability and safety at high speeds.
