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.

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.

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.

Barloworld CVT Technologies received an overwhelming response at our stand at the 6th International CTI symposium on Innovative Automotive Transmissions in Berlin, Germany. On display was a fully functional model of the iCVT complete with iCVT shifter as well as a rocker pin version model of the drive chain. This rocker pin type chain, also known as a silent chain, is based on existing chain technology and adapted for use in the iCVT. With this chain design the drive bars in the original design is eliminated while the chain pin tips engage protruding "ribs" on the partial drive section of the sheaves. See below picture.

A promotional video of the iCVT as well as a presentation of the iCVT is available for viewing below. The promotional video focuses on the operation and functioning of the iCVT while the iCVT presentation provides an overview of the company and includes topics like our business model and intellectual property. See below.

We have just returned from the SAE Commercial Vehicles exhibition in Chicago where our fully functional iCVT model has been on display. Once again the model proved to be a very powerful marketing tool in demonstrating the positive drive, shift under load properties of the iCVT concept that is unique in the world. The iCVT model is fully functional and includes an iCVT shifter. A preview video clip of the iCVT model has been added to our Recent videos section.

Our PCT (Patent Cooperation Treaty) application on the iCVT shifter has been granted while the PCT search report indicated that NO PRIOR ART was found by the PCT search. The iCVT shifter presents a solenoid activated mechanical, reversible, index on demand device.

Barloworld CVT Technologies visited the IAA Frankfurt motor show during September 2007 and demonstrated a fully functional model of the iCVT to interested parties. This model will also be exhibited at the SAE Commercial Vehicle Engineering Congress & Exhibition, October 30 - November 1, 2007 Rosemont (Chicago), Illinois, USA. See us at booth 902.

Jan Naude and Richard Michelson have been interview by the SA Mechanical Engineer and the iCVT vehicle was demonstrated. The article that appeared in this magazine is attached below as a pdf file.

Barloworld CVT Technologies will be displaying a fully functional model of the iCVT at the International CTI-Symposium – Innovative automotive Transmissions, 3 – 7 December 2007, Maritim Hotel Berlin, Germany. Jan Naude, the company’s MD will also give a presentation entitled “Development of a positive drive iCVT (Incremental Continuously Variable Transmission) session H3” .
