What Are the Two Parts of a Semi Truck?

Semi trucks are the big rigs that transport goods all across the country. They are a common sight on highways and freeways, and they are an essential part of the transportation industry.

But what exactly is a semi truck? A semi truck is composed of two distinct parts: the tractor and the trailer.

The Tractor

The first component of a semi truck is known as the tractor. This is the part that contains the engine, cab, and axles of a semi truck. The engine powers the vehicle and can be either diesel or gas-powered depending on its model.

The cab houses the driver and typically contains various amenities, such as air conditioning and comfortable seating. Finally, there are one or more axles located underneath the tractor which provide support for both it and the trailer.

The Trailer

The second component of a semi truck is known as the trailer. This is where goods are stored during transportation.

Trailers come in a variety of sizes, from small box trailers to large flatbeds that can transport large items like cars or construction equipment. Trailers have their own axles which provide support for them while they are being pulled by the tractor.

Conclusion

A semi truck consists of two parts: a tractor which houses the engine, cab, and axles; and a trailer which stores goods during transportation. Together these two components make up one complete vehicle capable of transporting goods across long distances efficiently.
