The Tractor
The tractor is the front part of the tractor trailer, also known as the cab. It is where the driver sits and controls the entire vehicle. Some of the important parts of the tractor include:The Engine
The engine is responsible for powering the tractor. It is usually located under the hood of the tractor and is responsible for generating the necessary energy to move the entire vehicle. Engines vary in size and power, depending on the type of tractor and the load it needs to carry.The Transmission
The transmission is responsible for transferring the power from the engine to the wheels. It helps to control the speed of the tractor and performs an essential role in shifting gears. Many modern tractors have automatic transmissions, but others still have manual transmissions.The Cabin
The cabin is where the driver sits while driving the tractor. It has seats, a steering wheel, and controls for various functions, such as air conditioning. The cabin also includes gauges for monitoring the engine's performance, like fuel level, speed, and temperature.The Trailer
The trailer is the container that holds the cargo and is attached to the tractor. It is made up of several components, including:The Axles and Wheels
The axles and wheels are responsible for carrying the weight of the trailer and the cargo. The number of axles and wheels varies depending on the size of the trailer and the load it carries.The Landing Gear
The landing gear is a support system for the trailer's front end when it is not attached to the tractor. It allows the trailer to stand on its own after it is disconnected from the tractor.The Rear Doors
The rear doors are the entry point for loading and unloading cargo into the trailer. Most trailers have two doors that open outward to allow for easy loading and unloading.The Suspension System
The suspension system is an essential part of the trailer, responsible for helping it absorb shock while driving on rough terrain. It also helps to keep the trailer level while in motion. There are several types of suspension systems, including:The Leaf Spring Suspension System
Leaf springs are a set of metal bars that absorb the shock while the trailer drives over rough terrain. They are commonly used in older trailers and are known for their durability.The Air Ride Suspension System
Air ride suspension uses airbags to absorb shock while the trailer is in motion. It provides a smoother ride than leaf springs and is more commonly used in modern tractors.
