What is the front beam assembly of a car
The front bumper beam assembly is a part of the car body structure, located between the front axle, connecting the left and right front longitudinal beams. It is usually made of high-strength steel, mainly to support the vehicle, protect the engine and suspension system, but also absorb and disperse the impact from the front and bottom .
Structural composition
The front bumper beam assembly is mainly composed of the following parts:
top plate : is fixed to the bottom plate of the body.
The first reinforcing plate : sandwiched between the top plate and the second reinforcing plate to enhance the overall structural strength.
the second stiffener : is fixed connected with the first stiffener plate and the top plate to form a closed force transmission path and improve the support of the beam assembly .
Function and importance
Front bumper beam assembly plays an important role in the car:
supporting role : support the main structure of the vehicle to ensure the stability and rigidity of the body.
protection : protect the engine and suspension system to prevent external impact on the internal structure of the vehicle damage.
absorbing impact force : in the event of a collision, can absorb and disperse the impact force, reduce the damage to the internal structure of the vehicle .
The main role of the front beam assembly of the automobile includes the following aspects :
Ensuring frame torsional stiffness and longitudinal load : The front beam assembly plays a crucial role in ensuring frame torsional stiffness and longitudinal load. It is connected to the beam by riveting, ensuring sufficient strength and stiffness to effectively withstand the load of the car as well as the impact of the wheel transmission .
Key parts supporting the vehicle : The front beam assembly is responsible for supporting the key parts of the vehicle and ensuring that these parts remain stable during the operation of the vehicle. By connecting with the beam, it is able to provide the necessary support to ensure the stability and safety of the vehicle .
Improve vehicle crash safety : the front beam assembly plays a key role in protecting the vehicle in the event of a collision. It can absorb and disperse the energy during the collision, reduce the damage to the vehicle structure, and thus protect the safety of the passengers in the car .
Improving the vehicle's aerodynamics : The design and shape of the front beam assembly also affect the vehicle's aerodynamics. Reasonable design can reduce wind resistance, improve fuel efficiency, and further optimize vehicle driving performance .
The front bumper beam assembly is not a collision beam . The front bumper beam assembly and the collision beam are two different components, although they are located in the front of the vehicle, but each has a different function and role.
Front bumper beam assembly features
The front bumper beam assembly is mainly composed of plastic bumper, buffer foam and beam. Its main function is to absorb and slow down the external impact force and protect the front and back of the body. Plastic bumpers have better elasticity and energy absorption capacity, which can play a buffer role in minor collisions, reduce maintenance costs, and have better protection for pedestrians and non-motor vehicles.
The function of anti-collision beam
The anti-collision beam is located inside the bumper and is usually made of a metal material, such as aluminum alloy or steel pipe. Its main function is to absorb energy in the event of a collision and protect the safety of the occupants of the vehicle. The anti-collision beam is installed on the longitudinal beam of the car body by bolts, which can play the role of absorbing energy for the first time in high-speed collision, and prevent the uneven force on both sides of the car body by balanced transfer of force.
The location and material difference between the two in the vehicle structure
The front bumper beam assembly is usually located at the front of the vehicle and is made of a highly elastic material such as plastic. The anti-collision beam is hidden inside the bumper and is usually made of metal. The anti-collision beam is bolted to the longitudinal beam of the car body, which can effectively absorb energy and transfer force during collision.
