A trailer wheel plays a crucial role in the trailer's suspension system, absorbing shocks and providing a smooth ride, especially when linked to a torsion axle.
When you are towing your trailer, each wheel moves up and down and the rubber inside the axle compresses giving an even wheel suspension for a smooth ride. This inherent movement and compression are key to how the system manages varying road conditions.
The Role of the Axle
While the wheel itself is a rotating component, its function in suspension is heavily dependent on the axle it's attached to. Different axle types handle this differently, but a common and effective type is the torsion axle, as highlighted in the reference.
Torsion Axles Explained
Unlike traditional leaf spring axles that link wheels on opposite sides, a torsion axle works differently:
- Independent Movement: A torsion axle allows each wheel to act independently to absorb any shocks from the road. This means that if one wheel hits a bump, the other wheel on the same axle is not directly affected, leading to better stability and control.
- Rubber Compression: Inside the axle tube, there are rubber cords or blocks. As the wheel moves up and down in response to the road surface, the axle arm twists, which in turn compresses these internal rubber elements.
- Suspension Action: This compression and resistance from the rubber provide the suspension effect, dampening the impact of bumps and vibrations before they are transferred to the trailer frame and its cargo.
Essentially, a trailer wheel, in conjunction with a system like a torsion axle, doesn't just roll; it actively participates in the trailer's suspension by allowing controlled vertical movement and using internal rubber components to absorb shocks, resulting in a more stable and comfortable towing experience.
