Inc. (KTR) is a wholly owned Canadian company, whose main activities are
research, development and specialty manufacturing of Ker-Train
technology comprises two fundamental transmission concepts: the Geared Variator and the Binary Logic Incrementally Variable
The Geared Variator is an infinitely variable transmission
utilizing non-circular gears that can be classified as an all-gear CVT.
Infinitely variable speed ratios from 0 to 1 are achieved with a
mechanical efficiency between 94% and 97%.
The Binary Logic
Incremental Variable Transmission can be used as either a close-ratio CVT
or a wider ratio stepped transmission with partial and full load
efficiency higher then conventional transmissions.
This system uses a sequence of co-planar gear sets to achieve a number of
gear ratios from 2 to 64.
development work has led to several spin-off technologies such as open
differentials, locking differentials, limited acting differentials,
transfer cases, a new planetary co-planar gear system, bi-directional
overrunning clutches and couplings.
