Presentation of Wet Multi-Disc Clutches

Our team at RTMG Performance, after extensive research and development under the most challenging conditions of dragster racing, managed to solve all the development issues of the 02E DQ250 gearbox clutches. Initially, we tested all friction materials, most of which had a lower friction coefficient compared to the factory clutch. Some of these materials not only had a lower friction coefficient but also produced residues, which clogged or sometimes even damaged the solenoids.

Na twee jaar continu testen op het Santa Pod-circuit in Engeland verzamelden we onschatbare inzichten om een van de meest uitdagende prestaties te bereiken: het vestigen van het Europese record op 0–400 meter (kwartmijl) met een tijd van 7,8 seconden en een eindsnelheid van 300 km/u met een 2,0L-motor.

How did we develop the clutch?

The clutch struggled with the incredible launch control of our engine, which delivers close to 1,400 horsepower in a 2.0L TSI Golf 6. After approximately every 5 passes, we would remove the clutch and inspect the wear. We tested numerous friction materials until we finally selected the current material.

The most critical point, however, was in the metal plates, which deformed as the car had to cover the first 18 meters as quickly as possible from a standstill, while at the same time ensuring the clutch did not overheat to avoid slipping at high speeds and under high turbo pressures. This led to extensive testing with many materials until we found a steel that had a high friction coefficient but was also highly resistant to high temperatures, as its crystalline structure prevented it from deforming as easily as other materials, including the factory parts. The material we use is thermally treated with tempering, which relieves stress and prevents deformation under the extremely high temperatures generated during the clutch's operation during the launch.

Het resultaat was niet alleen de tijd die we neerzetten, maar ook het baan- en Europese record voor voorwielaangedreven auto’s: 1,3006 seconden op de 0–18 meter.

A few words about power transmission.

Koppel wordt opgewekt door de motor en via de aandrijflijn overgebracht: vliegwiel, koppeling, versnellingsbak, differentieel, aandassen en uiteindelijk naar de wielen. Wat is hier de rol van de koppeling? De koppeling moet het toerental en koppel van de motor overbrengen naar de versnellingsbak tijdens de launch, waarbij de motor van 5.000 tpm in launch control gaat naar het aandrijven van de versnellingsbak op 0 tpm. Er zijn vaste en roterende componenten. In de koppeling zijn de vaste componenten de organische platen die met mechanismen op de koppeling zijn gemonteerd en met de versnellingsbak verbonden zijn, terwijl de roterende componenten bestaan uit de motor, het vliegwiel, de koppelingskorf en de metalen platen, die geïntegreerd zijn en daarop zweven.

As the driver initiates the launch by releasing the brake while flooring the throttle, the gearbox control unit compresses a piston that pushes the metal plates, squeezing the organic discs. The friction generated between these components causes the fixed discs to rotate at the same speed as the rotating ones.

To achieve this, several factors come into play, such as the friction coefficient, the surface area, the radius at which the friction materials are located relative to the axis, the cooling rate, and the heat dissipation, which is forced convection. We improved our results by:
a) Increasing the friction surface area.
b) Increasing the friction coefficient.

All of this was achieved by increasing the number of metal and organic discs and installing a bronze bushing instead of a plastic one for the stage 3 setup, to prevent it from melting at high temperatures.

Welcome to our team, welcome to the next generation of performance enhancement!
