Semi trucks are an important part of the transportation industry, and they require multiple parts to function correctly. The axles on semi trucks are an integral part of their functionality, providing stability and support for the heavy loads that the truck is carrying.
Understanding what these axles are called can help you to maintain your semi truck correctly.
Steering Axle
The steering axle on a semi truck is what allows the driver to control the direction that the vehicle is going in. This axle is located at the front of the vehicle and usually consists of two wheels that can be turned by a hydraulic system. This system uses pressurized fluid to move pistons which then turn the wheels in either direction, allowing for precise control of the vehicle’s direction.
Drive Axle
The drive axle is located at the rear of a semi truck, and it is responsible for providing power to move the vehicle forward. This axle consists of two or more wheels that are connected directly to a power source such as an engine or electric motor. When this power source is activated, it causes the drive axle’s wheels to rotate which then propels the vehicle forward.
Trailer Axles
In addition to the steering and drive axles, most semi trucks also have trailer axles which provide support for any trailers they may be pulling. These axles consist of two or more wheels that are connected directly to either a frame or bodywork on a trailer, providing stability and support for any loads contained within it.
Conclusion
In summary, semi trucks have three main types of axles – steering axle, drive axle, and trailer axles – all of which serve different purposes in helping it transport its cargo safely and efficiently. Knowing what these axles are called can be useful when maintaining your own semi truck as you’ll be able to identify them when they need servicing or repairing.
