TORSION CONTROLLER


Anti-friction centering ring Variator contrast spring

A secret from the Malossi racing department

Light, perfect: in its simplicity it is a concentration of technology.
The project and formulation of the materials are registered.

Extract from the archives of the Malossi Engineering technical office

CVT transmission systems
Chapter: contrast spring.
Objective
To reduce vibrations and stabilize the operation of the system
at any rotation speed and at any operating temperature.


Path

All the
metallic ball, roller and radial sliding fifth wheel systems existing on the market were taken into consideration, both on a theoretical and practical basis, and all the tests gave unsatisfactory results.
Prototypes were created with alternative, metallic systems, without
obtaining positive results. Only after exhausting laboratory and track tests did we arrive at the finalization of the Torsion Controller project.

Thesis
The component described above solves the following problems.
First problem: during the excursion of the shifting curve, in the
driven pulley group the bushing of the mobile pulley (torque corrector)
slides axially along the hub of the fixed pulley and describes a
small rotation, imparting a twist to the contrast spring. In some
cases the spring loses its position by rubbing on the mass holder plate
(dry metal on metal); in other cases, however, it remains integral with the
itself, thus determining contrasting forces, which are randomly different.
Second problem: the centrifugal forces that develop at high
rotation speeds influence the spring, which deforms and begins to skid
to the point of creating strong vibrations, annoying for the rider or harmful for
the engine, and which above all make the shifting curve inconsistent.

Result
After testing in the test room and on the track, the project is approved on
all types of scooters examined, with a full degree of satisfaction.
