Friction based ivts that don't require an epicyclic gear system.
Friction based ivts that don't require an epicyclic gear system.
(OP)
I have imagined an infinitely variable transmission (ivt) design and wish to clarify if it is something new.
It is a dynamic friction-based continuously variable transmission (cvt) that can go seamlessly to geared neutral without an epicyclic gear system and it is practical for larger torque, than conventional friction based cvts.
I have yet to find a patent for it after a few weeks of searching.
My preliminary internet research identifies the ivt types of: hydraulic, roller clutch, ratchet, and [a cvt + epicyclic gear system].
I am wondering if anyone is aware of friction based cvts that don't require an epicyclic gear system for the geared neutral?
Like everyone I don't want to re-develop something known.

IVT meaning " range of ratios of output shaft speed to input shaft speed includes a zero ratio that can be continuously approached from a defined "higher" ratio."

Without further details I think you will have trouble convincing people that a friction IVT can handle "larger torque".

Appreciate the feedback. I will proceed with its development.
Details are sparse because I have yet to file for patent protection.

There is a lot of information here - especially in the links.

I am looking forward to learning from its content.
