What Are the Axles Called on a Semi Truck?

Semi trucks are large and powerful vehicles that are used to transport goods over long distances. These trucks have several parts that work together to make them move, including axles.

The axles on a semi truck are responsible for transferring power from the engine to the wheels, and they also help support the weight of the truck and its cargo. So, what are the axles called on a semi truck?

The two main axles that are found on a semi truck are called drive axles and steer axles. The drive axle is responsible for providing power to the wheels, while the steer axle is used for steering. Both of these axles have an important role in keeping a semi truck moving and safe.

The drive axle consists of two or more differential gears that transfer power from the engine to the wheels. This axle is usually located at the rear of the truck, but can be found in front-wheel-drive trucks as well. The differential gears help to reduce friction between the wheels and provide better handling.

The steer axle is located at the front of a semi truck and is responsible for steering. This axle has two or more steering arms that attach to either side of the wheels and allow them to turn when steered by a driver. Each axle also has its own suspension system, which helps absorb bumps in the road.

Conclusion

Axles are an important part of any semi truck because they transfer power from the engine to the wheels and help support its weight. On semi trucks, these axles are called drive axles and steer axles, with each one having its own specific purpose in keeping a truck running safely.
