The performed RotorCVT test results were divided into two groups namely, indirectly measuring the mechanical efficiency and performing the ECE15 drive cycle.
Varibox is pleased to announce that the South African Technology Innovation Agency (TIA) has become a substantial Varibox shareholder.
The integration of the RotorCVT into a small vehicle, a 3 cylinder Chevrolet Spark, has been completed. All refinements to the mechanical part of the RotorCVT have also been completed.
The manufacturing of our RotorCVT demonstrator vehicle transmission has been completed. Currently testing of this standalone RotorCVT is in progress, after which the integration into a small vehicle will commence.
Varibox CVT Technologies will be presenting a paper entitled "Test results of a RotorCVT (rotor based ratcheting CVT" at the CVT 2010 CVT hybrid international conference, MECC, Maastricht, The Netherlands 17-19 November 2010.
We have completed the first phase of the testing of our 25 kW RotorCVT prototype with peak efficiency measured at 87.5%.
Further development and refinement is in progress to meet the target peak efficiency of 90%
Towards producing a demonstrator vehicle we have designed a complete 25-35 kW front wheel drive RotorCVT transmission which only weighs 32 kg. This transmission is geared neutral and includes a differential and reverse.
The test result efficiency graph and details of the above design can be downloaded below in pdf format.
Varibox CVT Technologies will also participate in the SAE-China 2010 International Symposium on Transmission Innovation and China Industrialization from April 23-24, 2010 in Beijing China.
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.
On display will also be models of the 78 ratio iCVT and RotorCVT.
Below is a link to a pdf file highlighting details of the above mentioned RotorCVT prototype.
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.
We are currently building a prototype of the feasibility design to be tested, to confirm the feasibility study simulation results.
The current design also indicate a significant weight reduction if compared to an equivalent commercial belt and pulley traction fluid CVT's.
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.
