What Is the Back of the Semi Truck Called?

The back of the semi-truck is an important part of the vehicle for both its design and function. It is an integral component of any semi-truck, and its name is the trailer.

The trailer is what carries all the cargo from one place to another on a semi-truck. It is usually attached to the cab by a fifth wheel and can be either a dry van or a flatbed.

The trailer has many components, including the frame, axle, suspension system, brakes, body panels, doors, and tires. The frame is the main structure that holds all of these components together.

It consists of steel beams that are welded together in a box shape. The axles are what support the weight of the trailer and its cargo. They are constructed from steel and can be either single or dual-axle designs.

The suspension system on a semi-trailer helps provide stability while in motion as well as dampening any bumps or vibrations that may occur while driving on rough roads. The brakes are used to slow down and stop the trailer when necessary. They can be either air brakes or hydraulic brakes.

The body panels provide protection for both the cargo and driver from wind, rain, snow, dirt, etc., while also helping to reduce drag for improved fuel efficiency. Doors are used to access the cargo area from outside and can either be manually operated or powered electronically.

Tires

The tires on a semi-trailer come in various sizes and types depending on their purpose and intended use. They must be able to withstand heavy loads over long distances without wearing out quickly.

In conclusion, what is known as “the back of a semi truck” is actually referred to as “the trailer.” This trailer consists of various components such as frames, axles, suspension systems, brakes, body panels, doors and tires which all play an important role in helping safely transport goods over long distances.
