Does the rear impact beam represent the attitude of car building? Why do many car companies reduce a

One of the things that everyone hates the most when buying a car is probably the reduction of car companies, and the most serious reduction is the anti-collision beam. Many people, this is distressed, feel that such an important safety device, should not be reduced, then according to the different installation positions, the anti-collision steel beam of the car can be divided into three types: front anti-collision steel beam, rear anti-collision steel beam and door anti-collision steel beam, the main role is to absorb collision energy, as far as possible to reduce the impact force damage to the body heavy beam, professional speech, is the collapse of energy absorption design.

In fact, many people's perception of the anti-collision steel beam is still relatively one-sided, we look at the body structure of the car will find that the front of the car, there are two weights, the front wall baffle and the front anti-collision steel beam composed of a mouth type, the engine, gearbox, front suspension and other important components of the key are installed in this opening, here, the front anti-collision steel beam plays a vital role, if not stepped, the front of the car is an open unstable structure, the normal driving of the car will be affected, In the event of a frontal collision, it will directly damage the weight of the body and some of the more important parts in the engine compartment, so the front sirder is an important part of the body structure, and no car manufacturer will reduce the front anti-collision steel beam.

The door anti-collision steel beam refers to the internal structure of the door is equipped with a beam to strengthen the structure of the side of the body, which is generally made into a steel pipe or a W-shaped steel plate shape. It is arranged diagonally in the door, extending from the bottom of the door frame to the bottom edge of the window glass, most of them are made of high-strength steel, these steel beams are not visible from the outside, but its role is very large, in the event of a side impact of the car, the protective effect on the members of the car is very obvious.

It is also part of the door structure, and almost no manufacturers will reduce the door impact beam, but the materials used and the manufacturing process are different. The rear anti-collision steel beam of the automobile is similar to the front anti-collision beam in structure, and the installation position is also similar, which is installed between the two longitudinal beams.

However, the structure of the rear of the car is very different from the front, there is no support between the two heavy beams in the front of the car, and if there is no front anti-collision steel beam, it cannot form a stable structure. The rear of the car is usually the tail box, which is supported by a high-strength plate between the two heavy beams, and this structure is originally very stable and reliable, and it is not easy to deform even if there is no rear anti-collision steel beam. In fact, the main function of the rear impact beam is to reduce the damage to the vehicle in the event of a collision.

The biggest reason why rear impact beams are mandatory for cars sold in the U.S. is because the Insurance Institute for Highway Safety is trying to reduce the cost of insurance. But to say that the rear anti-collision beam has no safety protection role at all, it is impossible to just say that the role is not so great.

In short, the front anti-collision steel beam is a part of the body structure, there must be a door anti-collision steel beam is also more and more important, mainly to deal with the side collision, and the rear anti-collision beam is only in the low-speed collision to reduce the car damage, to a certain extent to ensure the safety of the members of the car, there are some serious rear-end accidents on the Internet, in fact, whether there is a rear anti-collision beam, the result is the same, the speed reaches a certain level, no matter how much anti-collision steel beam is useless.

The rear beam can indeed represent too much on behalf of the enterprise to a certain extent, because it is related to the safety of the driver and passengers in the car.

The reason why many car companies choose to reduce the configuration is because of the consideration of cost, and the impact beam after the reduction can effectively reduce the cost. Personally, I think it's better not to buy such a car, because such a car is really not guaranteed for its own safety when driving on the road.

I don't think it represents, the reduction is mainly to save costs, but this kind of car can be bought.

I think it can represent that manufacturers will reduce their allocation in order to reduce costs, and I don't think they can buy it.

Summary. Hello Sorry for your question 1 If the anti-collision beam is only slightly deformed, it basically has no effect. 2. If the deformation of the anti-collision beam is not serious, and the car girder is not damaged but the deformation of the anti-collision beam is serious, the car girder will also be bent and deformed.

The anti-collision beam and the car girder are connected. 3 The anti-collision beam of the vehicle generally has a curvature, and when the front of the vehicle is impacted, the curvature of the anti-collision beam will be deformed due to the impact force, canceling most of the impact force. 4. The impact is not serious, which will only bend and deform the anti-collision beam, and will not affect the girder; However, if the impact is large, the deformation of the anti-collision beam can no longer absorb all the kinetic energy, and the remaining impact will make the beam bend inward or to one side.

The impact beam behind me was bent.

Hello, how bent is it?

Hello, can you take a full picture of me? That's how good it looks!

This kind of thing. In this case, the bend is not serious.

The impact on the car is relatively small.

Does the brake being rear-ended in D gear have any effect on the car gear?

New energy car. Hello, yes.

No matter which block it is in, it will have an impact.

The rear anti-collision steel beam has a very huge improvement for the improvement of the safety of the car. In a slight collision, the anti-collision steel beam can play a role in protecting the chassis, I have seen a rear-end Great Wall dazzling (it is estimated that it was hit by a large car), the rear tailgate is recessed, but the anti-collision steel beam is intact in front of the chassis. It is cheaper to repair the tailgate, and it is much more expensive to repair the chassis, and the rear anti-collision steel beam plays a very important role in reducing the loss of the owner in a slight collision.

As for the rear anti-collision steel beam advertised by some car companies in a violent collision, it can play a role in the stable chassis structure, so the rear anti-collision steel beam is omitted, which is completely joking with the lives of our consumers. For passenger cars, especially hatchbacks, anti-collision steel beams play a very important role. Without anti-collision steel beams, the force of the chassis is often not uniform in the event of a collision, and in this case, the chassis is very prone to twisting, denting, and even tearing.

When a strong metal (some models are equipped with high-strength synthetic materials, such as MG3) anti-collision steel beams are installed at the rear of the car, one can absorb a large amount of collision force through the energy-absorbing box of the anti-collision steel beam, and the other can evenly transmit the collision force to the two most stable points on the chassis. In high-intensity collisions, the rear anti-collision steel beam and the energy-absorbing box on it also play a very important role.

In many manufacturers' models, the foreign version has a rear anti-collision steel beam, but the domestic version does not have it because the domestic version does not have a safety test for rear-end collision like abroad.

But on the other hand, now 100,000 or even more advanced joint venture brand cars, the simple configuration of anti-collision steel beams seems to have become a trend. At first, only Japanese and Korean cars were simply matched, and now the gods are also following suit. On the **polo, the anti-collision steel beam is simply equipped.

For Polo and Fit, which are small hatchbacks with simple anti-collision steel beams, manufacturers are too black-hearted.

If it doesn't work, there is no need to install it, and there are still some benefits.

The collision of the rear impact beam at low speed still has a certain effect, and it is better than nothing. But for the safety of a car, the most important thing is the design of the entire body structure, which is much more important than what material is used for the crash beam.

In response to your questions, I would like to make some additional explanations. Everyone should know by now that the safety factor of a car in the event of a collision is mainly determined by its body structure design. The rear impact beam is only one component in the entire body structure, so we cannot judge the overall safety of a car by whether there is a crash beam or not.

But why is it said that the anti-collision steel beam is better than nothing? Because in some low-speed rear-end accidents, the anti-collision steel beam has a high probability of playing a certain role in protecting the frame, which can reduce the maintenance cost of the owner, so it is of course better than nothing. Regarding the material of the anti-collision steel beam, we should know that the car body should be designed to absorb the collision energy as much as possible, the anti-collision steel beam as a part of the safety structure of the entire car body, how to absorb energy, how much to absorb, each manufacturer's understanding and practice are different, so many cars of the anti-collision steel beam material is different, the design structure is different, the position is different, which is the final result of the car factory after experimental demonstration.

Therefore, I do not recommend changing the material of the crash beam yourself.

How important are car crash beams? After reading it, you will understand that there are so many functions!

At present, the function of the anti-collision beam in the automobile safety structure is to transmit the impact force to the rear joint, so that the longitudinal beam and the passenger compartment can bear the main force. If the passenger compartment is not deformed, the doors can be opened normally and the driver can escape, even if the vehicle is safe. In the overall security structure, its role as a guarantee is very necessary.

The main functions of the anti-collision beam are twofold: the first is to block the water tank or car body from being injured in a low-speed collision, saving maintenance costs; The second is to absorb a part of the energy during the collision, and then further absorb the energy through the collapsed structure, and then conduct it to the longitudinal beam structure to protect the member cabin.

When a sedan and an SUV of the same level collide at the time of the collision, the SUV should be a little safer than the sedan, because the special structure and ground clearance of the SUV are high, and the ground clearance of the sedan is low, so the SUV has an innate advantage in the collision. In terms of the front of the car, the front of the SUV is high, and the front of the sedan is low, whether it is a rear-end collision or a head-on collision with the bumper of the car, it does not play a role, and the core components just hit the anti-collision beam of the SUV, which is also a loss. Another point is that the chassis of the SUV is non-load-bearing and load-bearing, if the sedan meets the load-bearing model, there may still be hope, but if it encounters a non-load-bearing SUV, then there is basically no hope.

The material of the anti-collision beam is all-aluminum profile or steel, and under the same performance conditions, aluminum is 50% lighter than the steel anti-collision beam. The specific structural shapes include the "day" glyph and the "U" glyph.

The defects caused by the congenital structure are difficult to change, and most of the so-called losses are collisions in the low-speed range, and the safety of the members above the medium speed is stronger than anything else!

This question is related to the overall design of the vehicle. The car is subject to the overall body is shorter, and the force point of the vehicle skeleton itself is also low, and we all know that the direct force transmission is more conducive to the conduction of force, so as to facilitate the subsequent force dispersion. Then the connection point of the anti-collision beam must be connected to the horizontal position of the frame.

The design of the SUV itself is slightly higher than that of the sedan, so the frame of the whole vehicle is also slightly higher, and according to the above concept, the position of the natural impact beam is higher, which is unavoidable.

In addition, in the crash test, there is no relationship between high and low to determine whether the safety standard of the vehicle is or not. The collision between SUVs and sedans is a contradiction in the first place, and it is not yet possible to unify standards.

Not the same height, because of the site, ground clearance, suspension height is different... Crashing is not just an SUV. There are also collision walls, collision trees, collision size of the car, these anti-collision beams all play a role, and safety is not a decision of the anti-collision beam, there are other parts of the skeleton to take into account the degree, seat belts, airbags, active and passive safety systems and so on.

Speechless, do you know what a standard is??? I don't know, but I always know the difference between men and women???

The impact of changing insurance on the vehicle is definitely there, but it is not large. On the one hand, the replacement of the bumper belongs to the physical depreciation, after all, the original and the replaced are already two different concepts, so the depreciation will definitely be. But on the other hand, simply replacing the insurance will not have much impact on the overall performance of the vehicle, so it will not have much impact on whether the value of the vehicle or the depreciation of the vehicle will not be significant.

Generally speaking, the higher the original value of your vehicle, the greater the impact of details such as changing the bumper on the value retention rate of the vehicle. On the contrary, if the initial value of your vehicle is not high, then some aspects of the defects will not be magnified, compared to fatal injuries such as impact beams, chassis, engine, etc., replacing the bumper is simply not enough.

When a rear-end collision occurs, there are generally three factors that determine the consequences of the accident!

1. The difference between the weight of the two cars.

From a mechanical point of view, the greater the difference in mass, the farther away it will be hit, so the tonnage of the vehicle can play a role at this time. Although the car is light, it will suffer a big loss in the rear-end collision of a large car or a fast car.

2. The rear bumper anti-collision steel beam can play a role in absorbing impact.

What is the security impact? Replace the anti-collision steel beam after Yuedong.

The function of the rear anti-collision steel beam is to absorb the impact force through its own deformation at the first time of collision, so as to ensure the integrity of the rear body structure. Through the chassis ** we can see that the rear bumper of the general vehicle is behind the spare tire, and there are structural beams on both sides of the spare tire compartment, this area of the sedan is relatively long, while the hatchback is relatively short, generally only about centimeters, and in front is the seat of the rear occupants.
