One of the essentials of the logistics industry trucksThey can come up with very interesting equipment. Think of the trucks in movie scenes; driver honks at the top of your head pulls a rope. The horn, which is mounted on the steering wheel in standard cars, may also hang overhead in some trucks.

So why is there such a thing? After all, both trucks and passenger cars automotive engineers is produced by In addition, when we look at the consoles of today’s trucks, we see nothing but passenger cars. Get together, one of the must-haves for truck drivers. air horns Let’s take a closer look at that.

Thinking that trucks really only have air horns not true.

The picture shows the interior design of a Scania R-series truck. Just like cars, trucks also have standard horns. These horns operate like those in a passenger car, and the sounds they make are similar to passenger car horns. is similar.

If trucks have a standard horn, what is the reason for the horn on the head?

This, “air hornMoreover, these air horns are not only in trucks, but also in transport vehicles such as trains, ferries and ships. One of the horns used in passenger cars. much louder Air horns can also have different melodies.

The operating principle of air horns is different from that of passenger cars.

air horns; it doesn’t work like the electric horns we all have in our cars these days, to high air pressure needs. Air under high pressure remains trapped in a “pressure chamber”. A valve that releases air from this pressure chamber. valve consists. When the valve is released, in the horn”diaphragmThe so-called “material vibrates and creates sound waves. This sound wave is the result of the air horn”throatIt passes by taking off from the “” and spreads to the surrounding area. This is exactly the sound of “dari dari” you are all hearing right now.

How is compressed air supplied? Is there an oxygen cylinder?

In the years when the technology was not as developed as it is now, the air horn system in trucks to air brake systems was integrated. The driver could also use the compressed air, which also slowed the vehicle, for the air horn.

That’s where the drawn threads come into play.

We said high pressure air reaches the diaphragm using a valve; Here comes the sound. This is what we often see in movies The wire tensioning process ensures that this valve is opened precisely..

Years ago it was used in cars and trucks. mechanical systems dominated. Everything was not digital and electronic as it is now. There were also no functional steering wheels. Here are the air horns that work with a rope, especially in America at that time. has become a culture. That culture has survived to this day, and truck drivers can have air horns installed on their vehicles, even though it’s illegal to use them.

*A product we show as an example. Models with much larger compressors are also available.

Of course, for today’s air horns we need rope tension and integration into the braking system. it is not necessary. Because when you look at the air horn systems that are sold on the internet, you see that many of them have their own air compressors. Compressors that plug directly into the battery or cigarette lighter can be powered by a button or for nostalgia They are made with rope and can be used for air horns.

Here are the air horns of some trucks that make different sounds:
