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.

Nach zwei Jahren kontinuierlicher Tests auf der Santa Pod Strecke in England haben wir unschätzbare Erkenntnisse gewonnen, um eine der größten Herausforderungen zu meistern – den Europarekord über 0–400 Meter (Viertelmeile) mit einer Zeit von 7,8 Sekunden und einer Ausfahrtsgeschwindigkeit von 300 km/h mit einem 2,0-Liter-Motor aufzustellen.

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.

Das Ergebnis war nicht nur die von uns erzielte Zeit, sondern auch der Strecken- und Europarekord für frontgetriebene Fahrzeuge: 1,3006 Sekunden auf 0–18 Meter.

A few words about power transmission.

Das Drehmoment wird vom Motor erzeugt und über die Antriebskomponenten übertragen: Schwungrad, Kupplung, Getriebe, Differential, Antriebswellen und letztlich zu den Rädern. Welche Rolle spielt hier die Kupplung? Die Kupplung muss die Motordrehzahl und das Motordrehmoment beim Start an das Getriebe übertragen, wenn der Motor aus dem Launch-Control-Bereich von 5.000 U/min das Getriebe von 0 U/min auf Drehzahl bringt. Es gibt feste und rotierende Komponenten. In der Kupplung sind die festen Komponenten die organischen Scheiben, die mit Mechanismen an der Kupplung montiert und mit dem Getriebe verbunden sind, während zu den rotierenden Komponenten Motor, Schwungrad, Kupplungskorb und die Metallscheiben gehören, die integriert sind und auf diesem schwimmend laufen.

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!
