Is it necessary to install chassis armor in a family car???

There are actually two problems;

One is the problem of the guard plate;

1. The purpose of installing the lower guard plate is mainly to protect the engine from "supporting the bottom";

2. You can consider whether you need it according to the comprehensive factors such as road conditions and driving skills that you often drive;

3. The advantage is that it can effectively protect the engine; The disadvantage is to increase the dead weight, increase the fuel consumption, and put in the cost;

4. When a new car leaves the factory, some will have a very thin plastic shell, but it will not play a protective role; The more common materials on the market are aluminum alloy materials, steel plate materials, and carbon molecular materials; Its role is not the same; The carbon molecule is better in comparison; The first launch.

In the event of a major accident, the engine will automatically sink; But neither aluminum alloy nor steel plate can stop the engine from sinking; Only the carbon molecules will automatically break when they encounter extrusion force, so as to ensure personal safety; The second resin carbon molecule.

does not resonate; Thirdly, the weight of the resin is less than 3 kg, which is fuel-efficient; steel plates reach more than ten kilograms; At the market price, the cost of resin carbon molecules is about 200, and the cost of steel is more than 100;

The second is the so-called armor, which is actually a layer of anti-corrosion, and whether it is sprayed or not should be based on the needs of use; In addition, it should be reminded that many vehicles already have a coating on the chassis.

There are many functions of chassis armor, that is, it can make the car anti-corrosion and rust-proof, and the most important thing is that you don't have to worry about the bad environment, which will cause some splashed stones to cause damage to the car chassis.

Of course, if you often drive in some places with better road conditions, it is okay not to install it. The roads in the village are sometimes not cleaned properly, and some places are still gravel roads, so it is recommended to install them.

Chassis armor and, if convenient, chassis guards, for greater safety. It doesn't add much weight, so you don't need to worry about fuel consumption.

Be sure to choose a regular car repair shop to install it, and implement it in accordance with the standard, if the guard plate is not fixed firmly, it will become a danger.

It is still necessary to install chassis armor in the car, which can prevent the chassis from rusting.

1. Cheap cars may rust the chassis because of the material

It is impossible to use good sheet metal materials due to the restriction of the car due to the best and brand positioning, which is the result of rusting and being hardwareized, there is no doubt that the higher the car will generally use higher cost materials, such as hot-dip galvanized steel, all-aluminum materials, high-strength composite materials, automotive carbon fiber, etc., these automotive materials are naturally difficult to rust, who has ever seen the all-aluminum body, chassis will rust.

2. The external environment causes the chassis to rust

The external factors are mainly related to the use environment, and the environment in some places is poor, and there are more exposure to acid rain and corrosive dust; In some places, the weather is humid and rainy, resulting in serious corrosion of the chassis; In some places, the road conditions are poor, and the chassis is often knocked into the chassis or sand and gravel hits the chassis, causing surface damage and increasing the possibility of easy corrosion, such as the engine underguard, exhaust pipe, etc.

3. Human factors cause rust in the chassis

Driving often walks to waterlogged places, so that the chassis is in contact with water for a long time, resulting in chassis corrosion; If you don't wash your car for a long time, especially after rain, the rain will corrode the car body. Or often place the car in a humid place, such as the seaside, riverside, etc. Rarely maintain the exterior of the car, such as car washing, waxing, etc.; The tail of the exhaust pipe often accumulates water and is not cleaned.

Notes:

1. The more expensive the car, the more rust prevention treatment has been done at the factory, and the chassis armor can be considered for those vehicles that have not been treated with chassis. Chassis armor can reduce the damage of road sand and gravel to the chassis to a certain extent, and slightly knock the bottom, and more importantly, it can prevent the chassis from rusting prematurely to a certain extent.

2. Cars are often in a humid environment, and they should be more cautious about anti-rust treatment; At the same time, it is also necessary to prevent the aging of electrical external insulation. Pay special attention to the rust of the brake disc, the slight rust of the friction part can be removed by friction when braking; The parts of the brake disc that do not participate in friction can be protected from rust by self-painting or hard film anti-rust oil.

People's Daily Online - Why is your car so easy to rust After reading it, you will understand.

In fact, there are pros and cons to everything, the existence is reasonable, the chassis armor must also have its advantages and disadvantages, if we can accept its shortcomings, in line with the need for installation, then it can naturally be installed, and it will definitely be good for the vehicle.

1. Functional discussion

1.Climate impacts.

As the climate becomes more and more indistinct, high and low temperatures often occur, and in the south can often experience the rainy season for more than a month, or the high temperature that can fry eggs, these weather will often cause erosion on the bottom of the car, and the chassis armor of the car appears, which can make the vehicle less eroded by these factors.

But I think it's a bit of a chicken rib for this function, because we all know that the test of the car is very strict, and it will often be tested in some extreme weather, such as Turpan, Mohe and other hot and cold places, we can actually rest assured about the reliability of the vehicle, because most of us will definitely not be in that extreme environment all the time.

2.Sand and gravel impact.

During the driving of the car, there are often some small stones on the road, which will inevitably splash some at this time, and these foreign objects will damage the chassis of the car. In the long run, the damage to the chassis of the car is relatively large. And after the installation of chassis armor, it is possible to reduce the impact of these factors, thereby reducing the wear and tear of the chassis of the car.

I think it will have some effect on this, but if you think about it, there are not so many rough roads in the city, so it may not be used very often.

3.Drag the bottom. In some country roads, it is inevitable that there will be some bulges or depressions, and if you accidentally step on it when you drive over at this time, it will undoubtedly cause greater damage to the chassis of the car. If there is chassis armor, you can reduce the damage of the bottom and protect the original car chassis. I think this is the most important, especially for sedans, because the chassis of the car is relatively low, it is very easy to support the bottom in the city, I believe that many people have this experience, or more distressed.

This happens less often with SUVs.

4.Hedge. We all know that the better the vehicle is maintained, the higher the value, this is for sure, the installation of chassis armor, to a certain extent to protect the chassis, indirectly for the vehicle to maintain the value, the effect must be there, as for the degree, depending on the situation, some high, some low.

5. Driving comfort.

Because the chassis should achieve the effect of anti-collision and anti-rust, it is made of elastic materials and sealed, the effect is to improve the smoothness of vehicle driving, improve the NVH experience in the car, and have an effect on noise control, so the car with chassis armor is much better than the vehicle that has not been done in terms of driving comfort and noise control.

Second, whether it needs to be installed.

As the saying goes, "a bad car is bad first", this sentence is full of wisdom, the car chassis does not see the sun all year round, and it has to go through countless devastation, and the probability of natural damage is very large. If you often experience underpinning, bad roads, hot and humid weather, gravel roads, then, congratulations, it is necessary to install chassis armor, so that you can better protect your car.

I think it is very necessary for cars, especially new ones, to install chassis armor.

Chassis armor is not installed, it is essentially a kind of adhesive rubber asphalt coating made by high technology, the use method is to spray directly on the car chassis after thoroughly cleaning it, so that the role is: to prevent the chassis of the car from rusting, increase the sound insulation in the car, and increase the comfort of driving.

If you think that since the car leaves the factory, the chassis part is basically in an environment where there is no daylight, and dust, mud, rain, etc. are accompanied by dust all day long, which will accelerate the rust of the chassis and endanger driving safety. Think about how terrible it would be if the underside of the car was so rusty that it broke while you were driving.

And after spraying the chassis armor, you can also maintain the value of the car, when you buy a new car after a few years of driving and want to change a new car, at this time a clean and perfect chassis will add a lot of glory to your car, the buyer will also think that you are a person who cherishes the car, so that both parties will be more relaxed when trading, of course, your car will also be sold at a good price.

Therefore, I think it is still necessary to install chassis armor after buying a new car, after all, a small cost in the initial stage may reduce the trouble you may encounter later.

Must be followed! Be sure to follow it!

Some car dealers will give it away, so they will install it when they buy it, and some cars need to be installed by themselves! For example, at my carnival, on the first day I bought a car, I asked 4S to help me install the chassis armor.

Because most of the car chassis is relatively low, and the bottom of the front car is the main place to install important equipment, there is a very important engine here, and we usually stop to the high ground, walk on uneven ground, water on rainy days, etc., these are easy to damage our car bottom, and even rust. If you encounter big rocks on the road or come down from a steep uphill slope, it is easy to bump the chassis and even break the fuel tank and leak oil. So at this time, chassis armor is very needed.

The chassis armor is generally an elastic material with a thickness of 2-4mm, and the material looks very plastic, but the quality is very good. My car has been installed for more than four years, and I usually drive quite carelessly, sometimes I often park on the curb to make it easier to park, but even so, the chassis armor is still very good.

In the summer, the chassis armor, in addition to protecting the chassis of the car in front, also kept out the heat. He also reduces noise. The function is very powerful, and ** is not very expensive, many car accessories are more expensive than him.

Therefore, for the sake of your car, it is highly recommended to follow the chassis armor, especially the new car installed in the 4S store, and there may be new car discounts.

"Chassis armor" is also known as "chassis sealing", chassis armor and engine guards are not the same thing, don't get confused.

Due to its special parts, the working conditions of the automobile chassis are relatively harsh. In summer, the surface is hot and hot, the water is invading, the sand and gravel on the road surface in autumn are flying and impacting, the mud and dirt are easy to accumulate on the bottom fender and the curved part of the body edge, and the moisture of the accumulated attachment is not easy to evaporate, and it is not easy to clean up for a long time, coupled with the erosion of industrial snow remover after the winter rain and snow, the anti-rust layer coated on the automobile chassis is gradually damaged and loses its original anti-corrosion ability. Especially in some coastal areas, long-term saline erosion is more serious.

To solve this problem, we need to carry out a special treatment of the chassis "chassis armor" to enhance its ability to resist corrosion and rust in harsh environments. Now the mainstream is still the use of PVC (polyethylene resin) coating for treatment, the coating has high adhesion, high elasticity, and has the ability of anti-corrosion and moisture-proof, painted on the car site, not only can make the chassis isolated from the outside world, but also can achieve anti-corrosion, anti-rust, anti-collision, shock-proof, isolation of chassis noise function.

At present, the car has been done before leaving the factory for conventional plastic sealing, but in the process of use, the bottom of the body is susceptible to abrasions on the ground, stones, etc., especially in the event of an accident, the chassis sealing has been damaged, and the sealing effect before leaving the factory has gradually declined, so we need to carry out the chassis sealing operation from scratch.

Chassis armor, if you can, it's better to do it, after all, no one can guarantee that the original car armor will always work, and the driving environment of the vehicle will not become bad at any time. One more protection, one more rest assured.

For a lot of people who have just bought a new car.

People really can't wait to treat the new car as a baby, give their car insurance, film all kinds of care, and install chassis armor for the car, it is very common to film the car, but many people don't know what the chassis armor is, so let me introduce it below.

The name chassis armor is very domineering, but its construction is not so domineering, because it is not really armor, it is just a layer of rubber asphalt sprayed on the chassis of the car, about 2mm thick, which is a sticky, and non-toxic material, it is mainly sprayed on the chassis of the car and the contour of the fuel tank and wheels, is an elastic protective layer. Its specific functions are as follows.

Corrosion-resistant

There are still many uses of chassis armor, the chassis of the car is closest to the ground, so it will often encounter water, and the bottom of the car can not see the sun, so the chassis of the car will be more wet and rusty all year round, and the chassis armor can avoid this situation.

Resistant to small object impacts

In the process of driving, it is inevitable that there will be small stones and other impacts on the chassis of the car, although it is a small stone, but in the process of high-speed driving of the car, this impact is still very powerful, and the chassis armor can reduce the power of the stone hitting the chassis, although its thickness of 1-2mm can not completely eliminate the damage caused by the stone, but it can still effectively reduce the power of the stone.

Thermal insulation

When the temperature is relatively high in summer, the surface temperature must be the highest, and the temperature will be imported from the chassis into the car under the baking of the surface temperature, and the chassis armor can effectively insulate the heat to maintain the temperature in the car.

Put the bottom of the hit

This is actually very easy to understand, everyone who drives will basically meet, when in some uneven road sections, especially on the road with potholes, the chassis of the car will inevitably collide with the ground, which will cause wear and tear to the chassis of the car, and although the car armor can not completely resist this impact, it will also effectively slow down the power of this impact, and reduce the wear and tear of the chassis.

Whether to install car armor actually depends on the specific situation of the car, because some models themselves do safety work such as guardrails at the bottom of the car, but if their car does not have these protection measures, it is still necessary to install a chassis armor.
