What Are Axles on a Semi Truck?

An axle is an important part of a semi truck that helps it to move. It is a metal shaft that runs through the frame of the vehicle and connects the wheels.

The axles on a semi truck are also responsible for supporting the weight of the vehicle and its cargo, as well as transferring power from the engine to the wheels.

The axles on a semi truck come in two different types – rigid and steerable. Rigid axles are non-steering and are typically used for heavier loads, while steerable axles can turn to allow vehicles to make tighter turns. The number of axles on a semi truck will depend on its design and size, with larger trucks often having more than one axle.

Axles on a semi truck also come in different sizes and materials, which help determine how much weight they can carry. Steel is one of the most common materials used for axles because it is strong and durable, but other metals such as aluminum or brass can also be used depending on the application.

Semi trucks also have other components related to their axles such as brakes, suspension systems, drive shafts, and wheel bearings. These components all work together to ensure that the vehicle can move safely and efficiently.

Conclusion

Axles are essential components of any semi truck. They support the weight of the vehicle and its cargo, transfer power from the engine to the wheels, and allow for tighter turns when necessary.

Axles come in different sizes and materials depending on what type of load they need to carry, but steel is usually preferred due to its strength and durability. All these components work together so that semi trucks can move safely and efficiently.
