What is a Torsion Axle?

We depend on our utility trailers day in and day out. Whether you need one for work or if it simply helps you knock out chores around your property, your utility trailer needs to be ready when it’s time to get the job done. One of the key components that allow your trailer to be reliable is the torsion axle. 

Let’s take a look at what a torsion axle is and how it benefits your trailer as opposed to other types of suspension. 

So, What Is It?

A torsion axle is a type of suspension system commonly used in trailers, particularly utility trailers along with many other small to medium-sized recreational vehicles. 

It consists of a long, hollow, steel tube that contains a rubberized bar known as the torsion arm, which is responsible for absorbing shocks and vibrations. The ends of the torsion arm are attached to the trailer frame and the spindle, which holds the wheel hub and tire. 

When your trailer hits a bump in the road or you are towing it over uneven terrain, the torsion arm inside the axle tube twists, which in turn suspends the trailer. This works by creating a springing effect to absorb the impact. This prevents the trailer from bucking or swaying. 

One of the biggest advantages of torsion axles over traditional leaf spring suspensions is that they have fewer moving pieces which require less maintenance. Torsion axles also have better ground clearance as well as lowering the overall height of the trailer.

How Are They Useful?

A torsion axle offers several advantages for a trailer compared to other types of suspension systems:

1. Smooth Ride: Torsion axles provide a smoother ride for the trailer as the rubberized torsion arm absorbs shocks and vibrations more effectively than traditional leaf springs. This means less wear and tear on the trailer and its contents, and a more comfortable ride for passengers.
2. Better Handling: Torsion axles also offer better handling as they reduce the bounce and sway of the trailer. This is especially important for trailers that are carrying fragile or delicate cargo as it reduces the risk of damage.
3. Less Maintenance: There are no greased bolts, shackles or bushings to worry about, and the rubberized torsion arm is self-lubricating.
4. Better Ground Clearance: Torsion axles are mounted higher on the trailer frame than leaf spring suspensions, which means they offer better ground clearance. This is particularly useful for trailers that need to navigate rough or uneven terrain.
5. Lower Profile: Torsion axles can be used to lower the overall height of the trailer as the suspension system is integrated into the axle tube. This can be useful for trailers that need to fit into low-clearance areas, such as garages or parking structures.

Overall, a torsion axle is a reliable, low-maintenance suspension system that can provide a smooth ride, better handling, and improved ground clearance for a trailer. M&G Trailer has you covered with the utility trailers you need. Stop in today!
