Car front bars lower body action
The main functions of the lower body of the front bars of automobiles include the following aspects :
Reduced air resistance : The plastic part under the front bar is often referred to as a deflector. The deflector is tilted downward and connected to the front skirt of the body to form a whole, thereby reducing the air pressure under the car and reducing wind resistance at high speeds. This can reduce fuel consumption and improve fuel efficiency .
Protect the body : The plastic parts under the front bars are usually part of the bumper. The bumper is composed of an outer plate, buffer material and beam, which can not only absorb and slow down the external impact force in the event of a collision, protect the front and rear parts of the body, but also reduce the injury to pedestrians at low speeds .
Beautify the appearance of vehicles : the bumper not only plays a protective role in function, but also beautifies the vehicle in appearance and improves the overall beauty .
Improved vehicle stability : The deflector improves vehicle stability and safety by reducing wind resistance and preventing the rear wheel from floating. The lack of a deflector may cause the upward bearing force of the car to increase at high speeds, affecting driving safety .
Car front bumper body usually refers to the plastic parts installed under the front bumper of the car, its main function is to reduce the air resistance of the vehicle and improve the stability of the vehicle.
This part is commonly referred to as deflector . The main functions of the deflector include:
Reduced air resistance : The deflector improves fuel efficiency by guiding air flow and reducing air resistance at high speeds.
Improve vehicle stability : at high speed, the deflector can reduce the lift caused by the difference in air pressure between the bottom and top of the vehicle, ensure the driving stability of the vehicle, reduce power loss, and improve driving safety .
Protect the vehicle : The deflector, usually made of plastic, has a cushioning effect to absorb minor collisions and scratches and protect the underside of the vehicle from damage .
The deflector is usually secured under the bumper by screws or clasps and can be self-removed and installed. If the deflector is damaged or lost, the owner can buy a replacement for installation .
lower front bar failure can be caused by a variety of reasons, including impact, scratching, bumps during driving, etc. The lower body of the front bar is usually made of plastic or resin, so it is vulnerable to damage. The following are some common fault situations and their solutions:
Surface scratches : Scratches just below the front bumper are usually caused by hitting fine sand particles at high speeds. This minor surface scratch can be repaired using a paint touch pen, or choose to ignore the problem .
Deep scratch to reveal primer : If the front bumper is damaged under the interior and the primer is exposed, it may be caused by not paying attention to friction with objects such as steps when parked. You can use sandpaper to smooth out the exposed areas of the primer, and then repaint and wax. If necessary, you can go to the repair shop or 4S shop for repair .
Cracks or deformation : If the bottom of the front bumper is cracked or deformed, it may be due to an impact or other external force. If the crack is small and does not affect driving safety, you can continue to use the vehicle; If the crack is large or affects the safety of driving, you should immediately go to the auto store or maintenance site for treatment, may need to replace the new bumper .
Maintenance steps and precautions
Assess the crack : First assess whether the crack poses a threat to driving safety. If the crack is small and does not affect key components, the vehicle can continue to be used; If the crack is large or affects the safety of driving, it should be repaired immediately .
Replace the bumper : If you need to replace the bumper, you can choose the plastic or resin material that matches the car model, and choose the corresponding color and material according to the car model. It will need to be repainted after replacement to ensure consistency with the body tone .
