Bumper absorber in a car - what is it and why is it needed
Content
The buffer also has a third function, no less important - to protect the body from damage, and passengers who inadvertently find themselves in the path of the car from injury. Thus, the purpose of this element is to dampen the energy of the shock wave, minimizing the deformation of the remaining parts of the body.
A car body kit is needed not only for beauty. The element also performs other functions, for example, it softens the blow in case of accidents. Let's consider what a bumper absorber is in a car and what protective functions it performs.
Why does a car need a bumper
This body element is made in such a way as to harmoniously fit into the overall exterior design. Its other function is to increase downforce and aerodynamics. To do this, manufacturers use new synthetic materials, and the edges of the part are bent, which turns the element into a kind of spoiler.

It has been proven that on a flat track, the new body kit helps to achieve fuel savings of up to 20 percent per 100 kilometers, as well as increase the top speed by 50 km / h.
Unfortunately, on many cars now, especially budget ones, the buffer is made only for beauty. After a minor blow, he needs serious recovery. In order to somehow protect this element, a rubber band is glued to it, special plastic skirts are mounted, and a steel kenguryatnik is installed.
How to Reduce Pedestrian Danger
The buffer also has a third function, no less important - to protect the body from damage, and passengers who inadvertently find themselves in the path of the car from injury. Thus, the purpose of this element is to dampen the energy of the shock wave, minimizing the deformation of the remaining parts of the body.
To this end, they came up with a bumper absorber in a car. Translated from English, the word means "shock absorber" or "absorber". Kinetic energy is converted into thermal energy, then dissipated in the atmosphere. Naturally, this does not affect the movement and handling of the machine.
Confusion in concepts
If the bumper absorber in the car is needed to soften the blow, then the absorber is a completely different thing. There is a real confusion on the Internet about this now:
- An adsorber, or a special valve, traps fuel vapors during engine warm-up and prevents harmful fumes from entering the manifold. Thus, it protects the catalyst from premature wear. In fact, this is a kind of environmental filter installed in the engine compartment. Most often present in sedans A and B classes. The element begins to work immediately after the start of the power plant.
- Absorber is an energy-absorbing plate, which is a filler made of polymers.
The appearance of the absorber for cars
Below we will talk about the bumper absorber in the car, or a pillow, as it is also called.
What does a bumper shock absorber do?
According to some experts, the absorber is more of a publicity stunt and the use of a popular name. It is effective at a speed of 5-15 km per hour, and if the car goes faster than 20 km/h, then no shock absorber will help there.
On the other hand, glass beads are increasingly being used in the buffers of premium cars. This makes the products both durable and flexible. They withstand impacts of considerable force, rarely break, as they are deformed and straightened.
What is a bumper pad made of?
The shock absorber consists of several elements:
- honeycomb type plastic;
- expanded polystyrene;
- glass beads - used in expensive models of products;
- additives for absorption.
Is a bumper with a shock absorber effective?
Although the buffer of the car rarely breaks in frontal collisions due to its plasticity, a strong impact can damage it, despite the presence of a protective cushion (see photo of the front bumper absorber in the car).

Remember that the safety of driving is affected not only by the absorber and other deformable zones. The main thing is to always monitor the condition of the vehicle, timely identifying faulty components and parts.
