TORSION CONTROLLER Antifriction fifth wheel for variator contrast spring A secret from Malossi racing department Light, perfect: a technology extract in its simplicity. Design and formula of the materials are registered. Abstract from of Malossi Engineering R&D department archives CVT Transmission systems Chapter : contrast spring. Goal Pull down vibrations and to make the system operation stable at any rpm and temperature. Design path We have considered both on theoretical and practical basis all the existing fifth wheel systems: balls, rollers and radial sliding fifth wheels of metal type.…

TORQUE DRIVER The mobile driven split pulley comes from our racing department's many years of experience, and is manufactured with the best possible special nitrided steels in order to ensure a long life. This component called Torque Driver for its specific function of determining the exact shifting moment, was calculated to give the vehicle the maximum possible acceleration in connection with the specific power of any single engine. The spiral's peculiar shape was studied to fix the RPMs on the point of maximum power. It was expressly created to complete the development of boosted motors…

VENTILVAR 2000 It’s a fixed half-pulley with a diamond finish of the belt-side pulley surface and a redesigned working angle to further increase the gearing range. This component completes the Multivar and renders it unparalleled. Specially designed for the line of variable-speed drives for scooters, it further improves the performance of the drive belt. It is not just a simple accessory, but a very important part for guaranteeing the long life of all the transmission components. The temperatures produced inside the crankcases where variators work with V-belts are prohibitive at critical…

MULTIVAR 2000 MHR Next The variator has been improved to renew the transmission system as well as to exploit its extraordinary technical features: so we have come out with Multivar MHR Next . This new variator is the evolution of the previous generations, born from the very experience drawn from race tracks and from modern Cad-Cam technology; it allows to achieve the highest performance results. The mobile half-pulley is the component characterising the entire system and for this reason is subject to constant evolution. Designed with a larger diameter than the original, it allows a…
