Established in 2009, Varibox CVT Technologies is an intellectual property company specialising in the development of alternative positive drive CVT (Continuously Variable Transmission) concepts. The core business of the company is to invent and patent new positive drive CVT technologies, as well as prove the application of their inventions via tested prototypes. The company does not venture into the mass production of its transmissions, but rather license the technology to interested parties.
Varibox has successfully developed and tested three unique CVT concepts namely the ROTORcvt, icvt and RADIALcvt. Patents associated with these technologies cover 13 international countries including; Austria, Australia, Brazil, China, Countries bound by the European patent office, India, Japan, South Korea, USA and South Africa. It is the goal of Varibox to license the protected technologies to manufacturers of various transmission drive related products globally.
The History of the CVT dates back to the 15th century when Leonardo DaVinci sketched a stepless Continuously Variable Transmission in 1490. However, the first toroidal CVT concept was only patented in the 18th century, but it had to wait for the industrial revolution and the development of traction fluid technology before its manufacture.
It was not until the early 1980s that practical CVT application became viable. Early CVTs, whilst proving the efficacy of the engineering concept, relied on pure rubber belts to create the friction interface to change the radius between two interfacing metal surfaces. The resultant heat generation, vibration and friction losses characterised early CVT technology. With the introduction of traction fluid and special steels, steel on steel friction drive was made possible, CVT’s became more efficient with a higher power density. CVT’s in general currently shows a very high growth rate with production volumes doubling every 2-3 years. CVT’s however still suffers lower mechanical efficiency than manual transmissions while their hydraulic control systems make them heavy and expensive, while reducing mechanical efficiency.
In 2001, recognising the need for a design that eliminated the shortcomings of old-style CVT technology, inventor, Dr. Jan Naude partnered with Marinus van den Ende and Barloworld Equipment, a division of the global Barloworld group to establish a company called Barloworld CVT technologies. Through Barloworld CVT technologies, Dr Naude set out to develop prototypes that would lead to his revolutionary innovations. At this time Barloworld rendered much needed support in terms of R&D.
January 2009 marked the beginning of Varibox CVT Technologies following a management buyout from Barloworld, as well as the arrival of new investors. In 2014, Varibox successfully patented and prototype-proved its unique ROTORcvt and icvt inventions. As of 2016, a patent for another breakthrough technology called the RADIALcvt, a multi parallel power path CVT, with only one steel on steel friction drive interface in each path is pending.
Today, Varibox is continuing their endeavours as a separate entity and is marketing their patent protected inventions in order to find a licensing partner that will further develop and commercialise the products. Varibox is set to continue on their path to penetrate the gearbox industry and bring about major change.
Recent Varibox achievements include the following:
This is very encouraging for Varibox since above tests presents the first RADIALcvt prototype tests that are compared to commercial CVT's which have been in development for many years. The full details of the testing and the results can be viewed in chapter 8 of the attached design, simulation and testing document, attached as RADIALcvtDesignVer1.12.pdf. Some modifications to the RADIALcvt are in progress as well as a second round of tests at WITS University. A blog version of the test results can also be viewed at: http://www.varibox.com/blog/posts/2017/november/prototype-tests-place-radialcvt-efficiency-ahead-of-existing-cvt-s/
Varibox CVT Technologies have also been presented with numerous awards from prestigious corporate specialists over the years. These include:
