What is the front beam of a car
The front beam of the car is located in the engine compartment of the front part of the car, parallel to the longitudinal beam of the body . Its main function is to support and connect various parts of the car, such as bumpers and radiators. In the event of an impact, the front beam can effectively disperse the impact force and protect the safety of the occupants and other important components .
In addition, the front beam also has the following characteristics and functions:
Structure features : The front beam is usually made of high-strength steel, with high impact resistance and good energy absorption effect. It is usually used in conjunction with other structural parts of the body (such as collision beams) to form a complete collision protection system .
Safety protection : in the event of a collision, the front beam can absorb and disperse the impact force, reducing the injury to the occupants of the car. It is designed to deform during a crash, thereby consuming crash energy and protecting the vehicle and occupants .
material choice : automobile girder plate is mainly used in the manufacture of automobile longitudinal beam, beam, front and rear axle, bumper and other structural parts, the thickness is generally 4.0-8.0mm. This material has high strength and stiffness, and can meet the needs of automobiles in different working conditions .
The main role of the front beam of the car includes supporting and connecting various components of the car, such as bumpers and radiators, and effectively distributing the impact force in the event of an impact, protecting the safety of the occupants and other important components .
Specifically, the front beam of the car is located in the engine compartment of the front section and is connected parallel to the longitudinal beam of the body. Its main functions include:
Support and connection : The front beam supports and connects the various components of the vehicle, ensuring the stability and structural integrity of the vehicle.
dispersed impact force : in the event of impact, the front beam can effectively disperse the impact force, reduce the damage to other parts of the body, so as to protect the safety of the occupants and other important components .
In addition, the design and material choice of the front beam of the car is also very important. For example, BYD's patented technology improves the bearing effect of various collision forces by forming a double ring structure, further enhancing the safety of vehicles .
The handling method of the fault of the front beam of the automobile mainly includes two ways: correction and replacement .
Correction method
Using a girder corrector : Place the damaged vehicle on the girder corrector and use a clamp to secure the vehicle to ensure its stability during correction. Use the drawing tool to apply the tension opposite to the impact force to the deformation area, and gradually correct the skew of the front beam .
crowbar fine-tuning : In the correction process, a crowbar can be used to probe into the edge opening and fine-tune the concave part of the side of the frame, usually with remarkable results .
welding repair : If the front beam is cracked or broken, holes can be cut at both ends of the crack to prevent the crack from spreading, then polish the welding groove, use steel plates of the same thickness to cover the crack and weld repair .
Replacement method
Replace entire beam : If the front beam is severely deformed or damaged, the entire beam may need to be replaced. This method can restore the vehicle to normal use, but the maintenance cycle is longer .
repair without disassembly : on the condition that the vehicle is not disassembled, the butt welding technology can be used to repair the fracture or crack directly, or the internal and external surfaces of the front beam can be opened and repaired by butt welding technology. If necessary, dressing can be added to the fracture site to enhance the structural strength .
Preventive measures and maintenance suggestions
Regular inspection : Regular inspection of the front beam of the vehicle to detect and deal with potential problems in a timely manner.
avoid overloading : Avoid overloading the vehicle for a long time to reduce excessive pressure on the front beam.
professional maintenance : When the front beam fails, the vehicle should be sent to a professional auto repair shop for inspection and repair as soon as possible to ensure the repair quality and safety .
