Varibox CVT Technologies will be exhibiting a functional 30kW RotorCVT prototype at the 8th International CTI Symposium "Innovative Automotive Transmissions" from 1-3 December 2009.

The manufacturing of the RotorCVT prototype has been completed.

Testing is in progress and test results so far indicate that the RotorCVT has the potential for significant advantages if compared to current commercial automotive CVT’s in mechanical efficiency, weight and manufacturing cost. The prototype also features a geared neutral and thus do not require a clutch or torque converter.

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.

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.

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.

Barloworld CVT Technologies will be exhibiting at the International CTI Symposium "Innovative Automotive Transmissions" from 1-3 December 2008. We will be exhibiting the new iCVT model as well as RotorCVT models at stand 65.

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.

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.

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.
