What Are Trailer Suspension Units?
A trailer suspension unit is a vital component of a trailer's suspension system, responsible for providing support, stability, and shock absorption during towing. They are designed to absorb the impact of bumps, potholes, and uneven terrain, minimising vibrations and ensuring a smoother ride for both the trailer and the towing vehicle. Trailer suspension units come in different configurations, including braked and unbraked variants, to accommodate various trailer types, load capacities, and towing requirements. They play a crucial role in maintaining stability, enhancing safety, and improving overall towing performance.
What Types of Trailer Suspension are There?
- Braked Suspension Units: Braked suspension units incorporate braking systems into the suspension assembly, providing additional stopping power and control. These units are essential for towing heavier loads and are typically equipped with brake shoes for smooth and controlled braking.
- Unbraked Suspension Units: Unbraked suspension units lack integrated braking systems and are commonly used for lighter trailers or applications where braking assistance is not required. They provide basic support and stability for the trailer without the added complexity of braking components. TrailerTek stocks a large range of braked suspension hubs with cast hubs fitted and also unbraked suspensions without hubs.
- Shock Absorbers: Shock absorbers, also known as dampers, are often incorporated into trailer suspension systems to control the movement of the springs and reduce bouncing and vibrations. They help improve ride quality, handling, and overall comfort during towing.
Suspension Units FAQ’s
How do I know if my trailer suspension units need replacement?
Signs of worn suspension units include excessive bouncing, uneven tyre wear, sagging trailer height, and noticeable noises such as squeaking or clunking. Regular inspection and maintenance can help identify issues early.
Can I upgrade my trailer suspension units for better performance?
Yes, upgrading trailer suspension units can improve ride quality, stability, and load capacity. Consider factors such as the trailer's weight, intended use, and compatibility with the new suspension components.
How often should I lubricate my trailer suspension components?
It's recommended to lubricate trailer suspension components, such as the bearings, every 6 to 12 months or as per the manufacturer's guidelines. Proper lubrication helps reduce friction and extend the lifespan of the suspension system.
