The overrun damper on your trailer is an unassuming yet essential component for your safety and driving comfort. It ensures that your trailer doesn’t sway while braking and is smoothly decelerated. In this article, you’ll discover everything you need to know about trailer overrun dampers, from their function and maintenance to troubleshooting.
What is an Overrun Damper and Why is it So Important?
An overrun damper is a hydraulic damping system mounted between the towing vehicle and the trailer. When braking, the trailer’s drawbar pushes against the overrun damper. This resistance is used to activate the trailer’s overrun brake. Without a functioning overrun damper, dangerous swaying and accidents can occur. Imagine having to brake suddenly – an intact overrun damper can be life-saving in such a situation.
How a Trailer Overrun Damper Works
How the Overrun Damper Works in Detail
The overrun damper operates on a simple but effective principle. Inside the damper is a piston that moves within an oil bath. When braking, the piston is compressed, forcing the oil through small openings. This resistance gently slows the trailer. The damping force depends on the intensity of the braking process. “A well-maintained overrun damper is paramount for safe trailer towing,” says Dr. Franziska Müller, vehicle technology expert and author of the book “Safe on the Road with Your Trailer.”
Overrun Damper Maintenance and Troubleshooting
Regular checks of the overrun damper are essential. Test the damping effect by pushing down on the trailer’s drawbar. The resistance should be noticeable. Also, look out for leaks. Replacing the overrun damper is recommended at least every 8-10 years or after 150,000 km (approx. 93,000 miles). This prevents costly repairs and dangerous situations.
Benefits of a Functioning Overrun Damper
A functioning overrun damper offers numerous benefits: increased safety, improved driving comfort, protection against damage to both the towing vehicle and the trailer, and a longer service life for the braking system.
Overrun Dampers and Tongue Weight
Tongue weight plays an important role in relation to the overrun damper. Too little or too much tongue weight can impair the damper’s function. Therefore, ensure your trailer is loaded correctly.
Different Types of Overrun Dampers
There are different types of overrun dampers that vary in their design and performance. Before purchasing, inform yourself about which overrun damper is suitable for your trailer.
