Presentazione e vantaggi del volano bimassa RTMG PERFORMANCE

Another innovation in DSG automatic transmission systems from RTMG PERFORMANCE. The benefits of a dual-mass flywheel compared to the previous generation single-mass flywheels are significant. The importance of having two masses in the flywheel lies in smoothing out the explosions created by the combustion of the pistons during the third stroke of ignition.

In a five-cylinder TSI or TFSI engine, there are four powerful combustions in a full cycle of 720 degrees (two rotations), corresponding to the engine's power output. These piston explosions, which generate a reciprocating motion, are transformed into rotational motion through the crankshaft, and this motion is then transferred to the flywheel. The dual-mass flywheel acts as a damper for these vibrations. Through its springs, it prevents the peak combustion forces from being transmitted to the gearbox.

By smoothing out these forces, smooth power transmission from the engine to the gearbox is achieved, leading to longer component life and preventing the gears from wearing out. The manufacturer designed the dual-mass flywheel for the DQ500 gearboxes to handle up to 750Nm of torque for daily use.

But what happens beyond that? When the torque exceeds 750Nm, the springs inside the factory flywheel reach their limit, and the combustion forces beyond this point hammer the entire drivetrain—from the crankshaft and bolts to the gears, axles, and finally to the tires. The factory flywheel was not designed to handle hybrid or big turbo setups, slick tires for launches, or 10,000 RPM.

As enthusiasts of vehicle performance and having experienced repeated issues with the DQ250 transmissions in our own 2.0 TFSI race car, we decided to find a solution. Our engineers’ mindset is to design something that enhances performance with better mechanisms and materials. In the new flywheel we designed, we set the bar high in terms of quality, durability, and longevity, allowing it to handle from 770Nm to 1450Nm of torque. It was tested and developed in our own race car.

La prova del suo successo? Siamo riusciti a battere il record europeo con un tempo di 7,49 secondi utilizzando un motore 2.0L TSI, raggiungendo quasi 310 km/h al Santa Pod Raceway in Inghilterra nel 2022. Questo risultato ci ha motivato a investire ulteriormente in questo prodotto, poiché ha garantito un funzionamento fluido senza danni alla trasmissione, portandoci a diventare campioni europei.

Our latest version is made of high-strength chromoly steel (42CrMo4), and the splines undergo thermal treatment for maximum durability. The springs are twice as strong as the factory ones, but the key improvement is the progressive spring design. The initial springs are softer, allowing the flywheel to operate smoothly at lower loads. Another advantage over the factory flywheel is that ours is modular, meaning it can be serviced or upgraded for even more torque if needed.

The new floating design prevents the springs from contacting the moving masses, ensuring smooth operation and longer lifespan of the assembly. For those seeking ultimate performance, every component is dynamically balanced to 0.01G, and the overall weight is 20% lighter than the factory flywheel. Additionally, the internal Teflon components make our dual-mass flywheel more stable at high RPMs, preventing resonances and lateral vibrations.

Un vantaggio molto importante del nostro volano rinforzato è che, poiché le molle rinforzate non si comprimono completamente a coppie più elevate rispetto a quelle di serie, si evita la rottura dei bulloni tra volano e albero motore, in quanto tutte le forze d’urto vengono assorbite dalle molle rinforzate. Le molle lavorano in un ambiente lubrificato, assicurando che l’intero assieme funzioni in modo armonioso durante accelerazioni e decelerazioni, sia in condizioni di gara che nell’uso quotidiano.
