Abstract
One of two input disks 62 is fixed to an input shaft 13, the other input disk 62 and an output disk 63 are supported so as to be movable in the axial direction thereof, and the other input disk 62 is energized toward one input disk 62 by a cylinder 71, and power rollers 66 respectively stored in a pair of cavities are contacted with the input and output disks 62 and 63. The input shaft 13 is allowed to shift in the axial direction thereof, whereas the output shaft 14 is prevented from shifting in the axial direction thereof. And, a drive gear 25 formed in the output disk 63 and a driven gear 23 formed in the output shaft 14 are respectively composed of double helical gears.
Claims6
A double cavity toroidal-type continuously variable transmission, comprising:
- an input shaft:
- a pair of input disks disposed on outer portions of said input shaft in an axial direction of said input shaft, one input disk being fixed to said input shaft, the other input disk being supported thereon so as to be movable in the axial direction thereof;
- a pair of output disks respectively supported on an inner portion of said input shaft in the axial direction thereof so as to be movable in the axial direction thereof, said output disks respectively including drive gears;
- an energizing unit energizing said other input disk toward said one input disk;
- power rollers respectively stored in a pair of cavities formed between said mutually opposing input disk and output disk, said power rollers being contacted with said input disk and said output disk;
- and,
- an output shaft having driven gears being meshingly engaged with said drive gear of said output disk,
- wherein said input shaft is allowed to shift in the axial direction thereof, said output shaft is prevented from shifting in the axial direction thereof, and said mutually meshingly-engaging drive and driven gears are respectively structured by double helical gears which are prevented from relatively rotating with respect to each other.
