The Reeves Drive (also known as Variable-Diametre Pulley (VDP)) is a form of Continuously Variable Transmission (CVT) that has been around for 100 years. The technology is well-proven, and today is still utilised in the Reeves mechanical speed variators that we manufacture at All Torque in Preston. 
Even with many years under it’s belt, Reeves drives are still finding their way into many new applications, with many automotive manufacturers employing the pulley and belt system in their new CVT systems.
A run through the list of marques using CVT to aid with vehicle efficiency is impressive. Some manufacturers are employing a chain driven CVT (much like the PIV drive) whilst others are running the pulley and belt (Reeves) configuration.
CVT was deemed to be so good that it was outlawed in Formula One in 1994, for fear that those teams that could successfully implement the technology would have an unfair advantage over teams using traditional transmissions.
We are very happy that the world is catching on to just how effective the Reeves drive is in transmitting torque over varying speeds. You can rest assured that our Reeves Motodrives won’t be outlawed at any time!
