What is the rear beam assembly
The rear bumper assembly is an important part of the car, mainly composed of the following parts:
Rear bumper body : This is the main part of the rear bumper assembly, which determines the shape and basic structure of the bumper .
mounting kit : includes a mounting head and a mounting post for securing the cassette to the rear bumper body. The mounting head collides with the rubber buffer blocks on the taildoor, protecting the front and rear ends .
card socket : play a fixed and connected role to ensure the stability of the rear bumper .
elastic cassette : used to absorb and disperse the impact energy, protect the body .
anti-collision steel beam : can transfer the impact force to the chassis and disperse, enhance the anti-collision ability .
bracket : used to support the bumper and ensure its stability .
reflectors : improve visibility for driving at night .
mounting hole : used for connecting radar and antenna components .
reinforcing plate : to improve the side stiffness and perceived quality, usually with support bars, welded convex and reinforcing bars .
plastic foam : absorb and disperse the impact energy, protect the body .
Other accessories : such as rear bumper skin, protection plate, bright strip, bar iron, lower side circumference, frame, Angle, buckle, etc., enhance the anti-collision ability and improve the appearance .
The main role of the rear bumper beam assembly of the car includes the following aspects :
Disperse and absorb impact force : the rear bumper beam assembly is usually made of high-strength steel or other wear-resistant materials, its main role is to disperse and absorb the impact force when the vehicle is impacted, so as to protect the front and rear of the vehicle from external impact force .
Improve rigidity and strength : The design and shape of the bumper beam can affect the rigidity and strength of the vehicle. By improving the rigidity and strength of the bumper beam, the structural integrity of the vehicle in a crash can be better protected and the deformation and damage of the body .
Affects fuel efficiency and Aerodynamics : The design and shape of the bumper beam also affects a car's fuel efficiency and aerodynamics. Reasonable design can reduce wind resistance, improve vehicle fuel economy, and also help improve vehicle driving performance .
Protect the safety of back-end electrical appliances : for electric vehicles, rear anti-collision beams can not only reduce maintenance costs in low-speed crashes, but also protect the safety of back-end electrical appliances in high-speed crashes .
The replacement of the rear beam of the car is serious, mainly depends on the specific situation.
Seriousness of rear beam replacement
Major repair or not : Replacing the rear beam does not necessarily mean a major repair has been done. Usually, major repairs are not necessary only if the rear beam is damaged while the rest is intact. The standard for a major accident is damage to the longitudinal rail or wheel rotation position of the vehicle, in which case more serious repairs are required.
Impact on vehicle performance : The main role of the rear beam is to absorb the impact force in the collision and protect the safety of the vehicle and passengers. Replacing the rear beam usually does not significantly affect the overall performance of the vehicle, unless the rear beam and other critical components are damaged at the same time in a serious accident.
Effect on vehicle value : Replacing the rear beam may have an effect on the depreciation of the vehicle, but this effect is usually minor. If only a minor rear-end collision results in the replacement of the rear beam and bumper, it will have little impact on the overall value of the vehicle. However, if a major accident is involved, the depreciation of the vehicle may be affected.
The role and design of the rear beam
The rear beam (anti-collision beam) is an important part of vehicle safety, which can absorb and disperse the impact force during a collision, and protect the safety of the occupants of the car. It consists of a main beam, an energy absorption box, and a device connected to the vehicle, usually located in the front and rear parts of the vehicle.
Troubleshooting Suggestions after replacement
Consult a professional : If the rear beam of the vehicle needs to be replaced, it is recommended to consult a professional mechanic or car appraisal expert for more accurate information. They can conduct a full inspection of the vehicle and determine whether the rear beam needs to be replaced based on the actual situation.
Check other parts : When replacing the rear beam, pay attention to whether the longitudinal beam or wheel rotation position of the vehicle is damaged. If these critical components are also damaged, more serious repairs may be needed.
