The safety of Japanese cars has always been criticized by the Chinese people, believing that Japanese cars do not even install anti-collision beams, and that if something goes wrong, it is to move the coffin. So what is the role of the anti-collision beam? Is it really safe to remove the anti-collision beam?

It was stated in advance that Xiao Bian was not a pro-Japanese member and did not receive any red packets from Nissan car manufacturers. From an objective point of view, the concept of economical application of Japanese cars and the design idea of comfort and durability are very consistent with the actual use of Chinese people. So, why do Japanese cars remove the anti-collision beam and wring out the last drop of water in the towel?

First of all, we have to understand, what is an anti-collision beam?

The anti-collision beam is a device used to reduce the vibration force of the vehicle. Its two ends are connected to a low-speed energy-absorbing box with a very low yield strength, and then connected to the longitudinal beam of the car body by bolts.

The low-speed energy-absorbing box can effectively absorb the collision energy when the vehicle is in a low-speed collision, and minimize the damage to the body rail by the impact force, which exerts its protective effect on the vehicle.

A layer of foam buffer is installed on the anti-collision beam. Its main function is to support the external plastic bumper, relieve the collision force, and reduce the damage to the plastic bumper caused by the collision., Reduce maintenance costs.

What is the use of anti-collision beams?

The front and rear anti-collision beams are the first device for the vehicle to withstand the impact force. An important concept in the passive safety of the car body is to receive a little force and the whole body. A certain position of the car body is hit. If only this part is allowed to bear the force, the protection effect will be very poor. If the entire skeleton structure is allowed to bear the force at a certain point, the strength of the force at a point can be minimized, especially the front and rear anti-collision steel beams play an obvious role here.

When a car collides while driving, the anti-collision beam can effectively transmit the impact force from the left side (or right side) to the right side (or left side) of the car body, allowing the entire car body to absorb the collision energy as much as possible. In the event of a low-speed collision (generally below 15 km/h), the anti-collision beam can avoid the impact force on the front and rear longitudinal beams of the vehicle body and reduce maintenance costs.

However, it should be noted that the safety issues of anti-collision steel beams mentioned above are all when driving at low speeds, and the real purpose of anti-collision steel beams is to protect important parts during low-speed collisions to reduce maintenance costs. After an accident occurs at high speed, or the impact force that the anti-collision steel beam can withstand is exceeded, the existence of the anti-collision steel beam has no meaning.

Why remove the anti-collision steel beam?

In fact, in the face of the strategy of "configuration war" of domestic cars, many joint venture cars are at a loss. The competitiveness of a good car is not only fuel saving, but also price and configuration. If the joint venture car wants to keep its advantages, it has to compromise in some aspects. It is also what everyone thinks is a reduction in allocation. Whether it is in a place where you can see or not, of course, these "reductions" may be balanced to other "configurations". "In order to cater to the appetite of consumers and improve the competitiveness of models.

Summary: Any model, no matter how awesome the car is, if an accident occurs at high speed, the effect of the anti-collision beam will be minimal. The anti-collision beam is useful, but it does not play a decisive role. Safe driving is the fundamental guarantee of all safety. Now not only Japanese cars, but also many other cars have intentionally or unintentionally removed the anti-collision beams in order to cater to the market and reduce production costs, such as some Volkswagen models.
