Damper Science

The technology that goes into modern competition dampers is truly staggering. Below is information to better illustrate just what is going on:

 

Damper Anatomy

 

To the left is an interactive movie of anatomy of a modern Donerre competition damper along with its settings (courtessy of Donerre).

Click the arrow to play. When finished, hover over the individual components to highlight areas of the damper, or click the component title for an animated action display!

 

DETRA System

 

DETRA System
....

 

The patented DETRA system, developed after years of research, is aiming to get the wheel back on the ground as quickly and as often as possible.

DETRA Release Assistance

With this system we can have much higher rebound values than with the standard systems. Without destroying the grip (jacking down or packing down).

There are 2 seperate rebound settings, one with the DETRA inactive (the wheel in contact with the ground) and the other with the DETRA active (the wheel has lost contact with the ground). The system switches from one setting to the other automatically and instantly.
..

Shaft Speed Rebound Strength

The graph opposite shows the rebound strength when there is a loss of contact between the wheel and ground.

   

Rebound Speed Instant Strength

When the wheel gets back in contact with the ground, the system goes back to the initial setting - up to 20 times per second.

 

 

ART Anti Rolling Technology

 

Anti Rolling Technology
....

The ART (Anti Rolling Technology) is a system that controls the rolling of the vehicle using the g-forces that are applied to it (longitudinal or lateral).

This system can be used as an anti roll-, anti dive- or anti stall-device, or a combination of them.
The ART enables you to reduce the roll bar values which makes the wheels more independent thus generating better traction, it also makes the inside wheel NOT lift in the corners, thus generating better in corner grip.

 

Hydro Bump Stop

 


....Hydro Bump Stop Compression

 

Donerre's Hydro Bump Stop is characterised by its effective and progressive action.

A Hydro Bump Stop has several uses. It can protect the chassis in case of major shocks when the damper gets to maximal compression due to an unforseen event (big jump, unavoidable rock..). The hydro bump stop is there to preserve the chassis from these extreme compression situations.

It must absorb a maximum shock in a minimum of motion and in the most progressive way.
This bump stop could theoretically be made out of rubber but then this solution has 2 major flaws:

  • It “sends back” to the vehicle immediately: a rubber stop stores the compression energy and releases it immediately and brutally, which might lead to unpredictable chassis reactions.
  • It brakes in the same manner if we get to the compression limit at 0.1m/s or at 1 m/s.


The Donerre hydro bump stop will adapt its braking effort to the encountered speed.
So the hydro bump stop also has an energy dissipation role. With such a device the rebound phase is improved, and very quickly the vehicle gets back to its normal behaviour and comes under the control of the driver.

The last advantage of a hydro bump stop is to provide a very important improvement to the vehicle’s comfort which will result in greater comfort and safety of the driver and thus better performance.
