A variable automatic transmission for a motor vehicle comprising:
- a housing;
- a frusto-conical driven gear having a length and a plurality of spaced apart teeth on an exterior surface thereof and a hollow opening therein extending the length thereof and rotatably disposed within said housing;
- a first main power shaft having a plurality of sliding face gears slidably supported thereon wherein a first of said plurality of sliding face gears is adapted to engage an input gear from an engine and a second of said plurality of sliding face gears is a driving gear having a plurality of complimentary spaced apart teeth for engaging the plurality of spaced apart teeth of said frusto-conical gear;
- and
- wherein said plurality of spaced apart teeth on said frusto-conical gear includes a plurality of teeth having a first addendum and a plurality of spaced apart teeth having a larger addendum and wherein said teeth on said driving gear form a plurality of shallow teeth receiving openings for receiving and engaging said spaced apart teeth having a first addendum, and a plurality of relatively deep openings for receiving said spaced apart teeth having a larger addendum and separating said shallow teeth receiving openings.
A variable automatic transmission for a motor vehicle comprising:
- a housing;
- a first frusto-conical gear having a length, a plurality of teeth on an outer surface thereof and a hollow opening therein extending the length therein and rotatably disposed within said housing and said first frusto-conical gear having a plurality of spaced apart teeth on an inner surface thereof;
- a first main power shaft having a plurality of sliding face gears slidably supported thereon wherein a first of said plurality of sliding face gears engages an input gear from an engine and the last of said plurality of sliding face gears is a driving gear that engages the plurality of inner teeth of said frusto-conical gear;
- a second main power shaft and a second frusto-conical gear having a plurality of spaced teeth on an outer surface thereof and a plurality of teeth on an inner surface thereof and rotatably disposed within said housing on said second main power shaft;
- a second plurality of sliding face gears slidably supported on said second main power shaft and said second frusto-conical gear's plurality of outer teeth engaging the first frusto-conical gear's plurality of outer teeth;
- and
- wherein said plurality of spaced apart teeth on said frusto-conical gear includes a plurality of teeth having a first addendum and a plurality of spaced apart teeth having a larger addendum and wherein said teeth on said driving gear form a plurality of shallow teeth receiving openings for receiving and engaging said spaced apart teeth having a first addendum, and a plurality of relatively deep openings for receiving and engaging said spaced apart teeth having a larger addendum and for supporting said shallow teeth receiving openings.
