RotorCVT feasibility study completed

Varibox has contracted Hofer, a powertrain developer, in Germany to perform a feasibility study on the RotorCVT for application in a small passenger vehicle. The study was completed and indicated that the RotorCVT is viable for implementation in small passenger vehicles.


See us at Automechanika 18-21 March 2009, South Africa

Varibox CVT Technologies will be exhibiting models of its iCVT and RotorCVT as well as our iCVT test vehicle at Automechanika, South Africa from 18-21 March 2009.


Varibox CVT Technologies becomes an independent entity

January 2009 marks the coming of age of Varibox CVT Technologies, previously known as Barloworld CVT Technologies, as we are now able to continue our endeavours as a separate entity from the Barloworld Group. Following a management buyout, as well as the investment of a number of investors, Varibox CVT Technologies was established.

US RotorCVT patent granted!

The US RotorCVT application has been granted. Claim 1 of this granted patent, US7416506, protects the conceptual functioning of the RotorCVT and therefore will also protect the different implementations of the concept in different applications.


iCVT conjugate cam driven ratio shifter and animation

The most recent further development of the iCVT oscillating shifting mechanism is presented below. This Oscillating shifter is driven by a conjugate cam pair and is integrated in the sheave unit. The picture to the right presents the conjugate cam pair.


New iCVT shifter mechanism

The most recent development of the iCVT includes a radically simplified oscillating shifting mechanism that replaces the Geneva wheel based shifter mechanism. This Oscillating shifter is driven by a barrel cam, coupled to a locking mechanism that results in accurate high speed shifting.


International trip and rotorCVT model

We will be traveling to Europe, China and Japan from 13 to 27 February 2008 and would like to invite any parties interested in our technology to Contact Us for a full demonstration of our models and technology.


RotorCVT compact design and granted European patent

Our European patent application on the rotorCVT has been granted and validations are in progress. The granted European specification, EP1592900B1, can be downloaded below. An animation of a new improved compact rotorCVT design has been added to our Recent Videos. See Compact rotorCVT. This design presents a complete drive train and includes the rotorCVT, a clutch, a forward gear, reverse gear, low gear and a differential. All this functionality is configured around the output axle making, use of a single planetary gear set.
