What is the rear leaf lining of a car
Automobile rear leaf liner , also known as rear leaf liner , is the non-metal protective layer at the rear of the automobile, installed on the inside of the rear leaf liner. Its main functions include sound insulation, heat insulation, body protection and increased aerodynamic performance .
Definition and location
The rear leaf liner is located on the inside of the rear leaf of the car and is usually made of plastic, resin or other lightweight materials. It is connected with the body through a specific installation method, and plays a role of beautiful and protective body .
Main function
sound insulation : the inner lining of the rear leaf board can effectively isolate the noise and heat from outside the car, creating a more peaceful and comfortable riding environment for the passengers in the car, especially at high speed, the sound insulation effect is more significant .
body protection : As a non-metal protective layer, the inner lining of the rear blade can resist the impact of external objects such as splashing stones and sand to a certain extent, and reduce the damage to the paint of the body. In the event of a minor collision, it can also play a certain buffer role to protect the body structure from serious damage .
Increased aerodynamic performance : The design of the rear leaf liner takes into account the principle of aerodynamics, through its specific shape and material, it can reduce the wind resistance of the vehicle during driving to a certain extent, improve the fuel economy .
Maintenance and replacement suggestions
Although the rear leaf liner does not need to be maintained and replaced as frequently as core components such as engines and transmissions, the following points still need to be noted in daily use:
regular inspection : regular inspection of the leaf liner is damaged or loose, if necessary, should be repaired or replaced in time.
keep clean : regularly clean the sand and debris on the lining of the leaf board to maintain its good working condition and extend its service life.
Pay attention to the use environment : try to avoid driving for a long time in bad road conditions to reduce the damage to the rear leaf liner .
The main role of the rear leaf liner (rear fender) of the automobile includes the following aspects :
reduced drag coefficient : The rear fender is usually designed to be slightly arched and slightly raised outward to optimize air flow and reduce air resistance, thereby improving driving efficiency and stability .
vehicle protection : The rear fender can prevent the sand and mud rolled up by the wheel from splashing onto the bottom of the carriage, reduce the damage and corrosion of the chassis, and protect the long-term performance of the vehicle .
improved vehicle stability : The rear fenders are designed with aerodynamic considerations in mind to optimise air flow, reduce potential wear and damage and ensure that there is no scraping between the wheels and the fenders .
beauty and body modeling : the design of the rear fender can also improve the body modeling, maintain the smooth lines of the body, guide the airflow, and further reduce the air resistance .
Material and design characteristics of rear fender :
material diversity : The rear fender can be made of plastic, steel, aluminum alloy and other materials. For example, plastic materials are widely used for their cushioning and ease of maintenance.
Aerodynamic design : Rear fenders are usually designed with arched arcs protruding outward to optimize air flow and improve driving efficiency .
Maintenance and inspection recommendations : Although the rear fender is not as susceptible to damage as the front fender, it is still necessary to check its integrity and function regularly to ensure that it can effectively perform its protective and aerodynamic role.
