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.

Após dois anos de testes contínuos na pista de Santa Pod, em Inglaterra, reunimos informações inestimáveis para alcançar um dos feitos mais desafiantes — estabelecer o recorde europeu nos 0-400 metros (ou quarto de milha) com um tempo de 7,8 segundos e velocidade de saída de 300 km/h utilizando um motor de 2,0 L.

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.

O resultado não foi apenas o tempo que alcançámos, mas também o recorde da pista e o recorde europeu para carros de tração dianteira: 1,3006 segundos nos 0-18 metros.

A few words about power transmission.

O binário é gerado pelo motor e transferido através dos componentes da transmissão: volante do motor, embraiagem, caixa de velocidades, diferencial, semieixos e, por fim, para as rodas. Qual é o papel da embraiagem aqui? A embraiagem precisa de transferir as rotações e o binário do motor para a caixa de velocidades durante o arranque, onde o motor passa de 5.000 RPM em launch control para fazer girar a caixa a 0 RPM. Existem componentes fixos e rotativos. Na embraiagem, os componentes fixos são os discos orgânicos montados com mecanismos na embraiagem e ligados à caixa de velocidades, enquanto os componentes rotativos incluem o motor, volante do motor, cesto da embraiagem e os pratos metálicos, que estão integrados e flutuam sobre ele.

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!
