Trailer Spring Axle

Types of Trailer Axles

Trailer axles are normally divided into two different types: Spring axles and torsion axles. While these two types of axles perform the same basic job, the way they go about suspending and cushioning the trailer load is completely different.

Spring axles
The function of the spring shaft is to use stacked metal plate springs located below or above the axle beam to support the weight of the trailer. The spring shaft is available in single axis, double axis, and three axis configurations. In both dual trailer and triple trailer, the leaf springs are connected through an equalizer. Equalizer helps to distribute the weight of the trailer more evenly across all axles. Spring axles are common on all brands and models of trailers because they are more cost-effective than torque.

Torsion axis

The torsion shaft handles suspension travel and shock absorption by using rubber ropes or sleeves inside the shaft tube. The torsion shaft does not use leaf springs, but uses compressed rubber to provide the required suspension support. Each wheel works independently of each other. The torque shaft is also directly bolted or welded to the trailer frame, which increases the stability and structure of the trailer frame.

Which Is Better For Your Trailer? Torsion Axles or Spring Axles:

Benefits	The smoothness of the torsion axis. They adopt a direct design that relies on the tension of the rubber components inside the axle to absorb interference. Even when there is no load on the trailer, this twisting and compression mechanism is very smooth and slides very well. In addition, there is no contact between the metal inside the axles, making driving quieter. Moreover, due to its design efficiency, it only requires minimal maintenance. There are fewer moving parts, and there are no components inside the axle that rub against each other, thereby reducing wear and corrosion.	The spring shaft is the most typical shaft anywhere, for a reason. Spring axles are very popular among consumers because they are cheap. The ease of production and installation makes it a more cost-effective axle choice. Parts are also widely available, which means that in the long run, their costs may be lower. Maintenance and repair are also very simple. If the spring shaft is broken, the parts can be replaced separately. In addition, welding is not required during the repair process. The load-bearing capacity of a spring shaft is much higher than that of a torsion shaft. In addition, because all the fragments are visible outside, you can repair them before any damage increases.
Cons	torsion axles come with several drawbacks too. First, the connected structure of torsion axles entails that any substantial repairs will involve the removal of the axle.	Spring shafts, like torsion shafts, have several drawbacks. Firstly, its ability to reduce vibration is limited. Due to the fact that the spring shaft is a sturdy component, vibration may easily propagate through the trailer frame. Another drawback is its relatively limited adaptability. When you need adjustable ride height, using a spring axle may be somewhat inconvenient.
