The RADIALcvt is a multi-parallel power path type of continuously variable transmission (CVT), that consists of only one steel-on-steel friction drive interface in each path.
RADIALcvt features a single friction drive interface in series and at least 6 power split friction drive parallel paths. A constant input radius on the friction drive input make it possible to use a constant clamping force which is provided by springs. Therefore RADIALcvt concept has no hydraulic control system.
The RADIALcvt has a very large radius variation on the friction drive output which provides the ratio variation. Due to the fact that the Radial drivers are clamped between two opposite rotating disks, results in the largely cancelling out of the forces on the Radial drivers. The RADIALcvt’s first ratio is hard geared to eliminate the “kerb test” issue common with push belt CVT’s.

With Patents granted and a solid concept and design, VARIBOX CVT Technologies were keen to show, on more than just paper, the benefits of the RADIALcvt. And after completing a comprehensive simulation, the benefits are obvious. The simulation was completed in May 2017 and shows very promising results, demonstrating the innovation's enormous fundamental advantages over current commercial and known developmental CVT's.
