What is the front beam assembly of a car
The front bumper beam assembly is a part of the automobile body structure, located between the front axle, connecting the left and right front stringer. Usually made of high-strength steel, it mainly supports the vehicle, protects the engine and suspension system, and also absorbs and disperses impact forces from the front and bottom .
Structural composition
The front bumper beam assembly usually consists of the following parts:
top plate : is fixed to the bottom plate of the body.
The first stiffener : is sandwiched between the top plate and the second stiffener plate, and is fixedly connected with the top plate and the second stiffener plate.
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
The front bumper beam assembly plays an important role in vehicle design and safety:
supporting role : provides the structural support of the body to ensure the stability and rigidity of the vehicle.
Protection : Protects the engine and suspension system from external shocks.
energy absorption and dispersed impact : in the event of a collision, it can absorb and disperse the impact force to protect the safety of the vehicle .
The front bumper beam assembly plays a vital role in the automobile structure, the main role includes the following aspects :
Absorb and disperse collision energy : When the vehicle crashes, the front bumper beam assembly can effectively absorb and disperse the impact force, reduce the damage to other parts of the body, so as to protect the safety of the vehicle and passengers .
improve the overall rigidity and strength of the vehicle : through its structural design, the beam assembly can significantly improve the rigidity and strength of the vehicle to ensure the stability of the vehicle structure in various working conditions .
supporting key parts : The front cross beam not only supports the key parts of the vehicle, but also connects with the cross beam by riveting to ensure that it has enough strength and stiffness to withstand various impacts from the car and wheels .
aerodynamic action : the beam in some designs will also affect the aerodynamic performance of the vehicle, optimize the fuel efficiency and driving stability of the vehicle .
Aesthetics and protection : The front bumper not only has a practical function, but also can add beauty to the vehicle and enhance the overall appearance of the attractive. At the same time, it also protects the vehicle in the event of minor crashes, reducing damage .
The front beam of the car is usually located behind the front bumper, including the front beam, the front longitudinal beam and the rear longitudinal beam.
Front beam : Located behind the front bumper, is the first beam, also known as the girder or part of the frame. It is the base of the car, composed of two longitudinal beams and several beams, supported on the wheels by the suspension device, the front axle and the rear axle. The main role of the front beam is to support and connect the various assemblies of the car and withstand various loads from inside and outside the car.
front longitudinal beam : located under the engine, above the ingot beam. The main function of the front longitudinal beam is to withstand the collision force from the front and protect the front structure of the vehicle.
rear stringer : located under the trunk. The main function of the rear longitudinal beam is to support the rear structure of the vehicle and withstand the collision force from the rear.
Together, these components form the front structure of the car, ensuring that the vehicle provides adequate protection in the event of a collision, while supporting and connecting the car's individual assemblies.
