Dampers – Topic Overview

What Is A Damper?

A damper can be described as a unit that contains oil within a tube and a piston in it. The primary function of the piston is to move up and down through the oil. The piston itself has a small precise hole that allows the oil to pass through at a certain speed.

To better understand how it works, we have to first look at its construction. Therefore, a dumper contains the following pieces:

• The body (tube) – The body is the housing that contains other components. The body has external threads for mounting and to allow the spring base to be wound up and down. This allows one to adjust ride height and pre-load.

• The Piston – The piston connects the inserts and chassis into the body. It moves through the oil when the dumper is working.

• Shims – The ship sits at the upper part of the damper and flexes whenever oil passes through the piston. Shims are generally tuned based on the spring rate. NOTE: it is very important to get the tuning right when designing a damper system.

• Adjuster needles – This is a pointed needle that screws in and out of the hole to allow more or less oil to pass through the piston. In other words, it is used to control the flow of oil and affects its characteristics and rebound.

• The oil – We all know what is oil. The only thing is that there are many kinds or types of oils. In this case, this is a special type of oil intended for the damper. Remember, damper oil is chosen based on viscosity. One that can pass through the holes and past the shims to control the flow rate.

Nitrogen – This is a non-reactive gas that is used to pressurize the oil within the damper. It is designed to make the damper operate as designed. It is also used to keep the pressure in the reservoir up so that it can keep up with the demand without delays. Finally, it acts as a spring in the damper to smoothen the damping effects at high speed.

The Work Of A Damper

The primary function of a dumper is to control the motion of the spring as well as manage the weight transfer and shock load. Without a damper, the springs will oscillate violently when driving a vehicle. This is not idyllic when one is trying to retain balance and control of a vehicle; or when trying to maintain continuous wheel contact on the road to increase grip. For this reason, it controls how much the springs can oscillate and return. For readers in Peterborough see ‘peterborough land rover show‘.

Another function of a damper is to control how fast a coil or spring can compress or extend. The technical term for this is known as the bump and rebound response. This is very important as it controls how fast a vehicle’s shocks can roll in or out (compress and extend) around corners. This is what prevents under or over steering in and out of bends in a vehicle.

The final function of a damper is to act as a shock absorber. It plays a huge role when it comes to road surfaces that are not even, and the wheels need to absorb as much shock as possible to prevent an uncontrollable ride. Remember, the better the shock absorption, the more the wheels will have contact with the ground and prevent jolting. This is why in rallying vehicles; you will find them having high-quality shock absorbers.
