The RADIALcvt, a new CVT (Continuously Variable Transmission) being developed by Varibox provides an excellent transmission solution to pure electric vehicles, because of its simplicity and fundamental advantages with very high mechanical efficiency.

The global demand for continuously variable transmissions(CVTs) in the passenger vehicle sector is enjoying an unprecedented growth rate intensifying competition to develop the most efficient CVTs among auto innovators. In this article, we take a look at how two CVT solutions from Dana and Varibox CVT Technologies fare against each other in terms of mechanical efficiency and cost effectiveness.

Current commercial CVT's in the passenger vehicle market face criticism for being laden with inherent deficiencies like hydraulic control losses, friction drive losses, high manufacturing costs, high contact stresses requiring special materials, as well as being heavy, which results in expensive and heavy CVT solutions which are not sufficiently viable in small vehicles below 50 kW. For this reason, Varibox CVT Technologies Pty (Ltd) developed the RADIALcvt, a multi-parallel power path type of CVT that consists of only one steel-on-steel lubricated friction drive interface in each power path.
