Patent ID: 8490507

Claim:
A rotary swash plate continuously variable transmission, comprising: a driving mechanism, an output mechanism and a casing ( 24 ), said casing having a slide stem holder including at least three spline holes, said driving mechanism comprising a rotational swash plate ( 9 ) and at least three slide stems, said swash plate having a periphery, said slide stems disposed parallel to each other in said spline holes and spaced equiangularly relative to the periphery of said swash plate, a spring disposed in each said spline hole biasing said slide stems toward said swash plate, said swash plate having a variable angle of inclination relative to said slide stems, each slide stem equipped at one end with a one-directional rotary helical gear ( 13 ), said one-directional rotary helical gear rotatable about said slide stem in only one direction, the other end of said slide stem contacting and sliding on the surface of said swash plate causing said slide stem to reciprocate axially, said output mechanism comprising a one-way rotational output shaft ( 16 ) and a center helical gear ( 14 ) disposed on said output shaft ( 16 ), each of said one-directional rotary helical gears in direct sliding engagement with said center helical gear, such that when each said slide stem moves in one direction said one-directional rotary helical gear does not rotate and thereby causes said center helical gear to rotate, and when said slide stem moves in the opposite direction said one-directional rotary helical gear rotates.
