Abstract
A constant power mechanical transmission with seamless, ripple free, infinitely variable torque multiplying outputs comprises an input shaft and an output shaft. The input shaft is coupled to a pair of oscillating levers whereby rotation of the input shaft causes oscillation of the oscillating levers in opposite directions. The oscillating levers are linked to the output shaft with one-way clutches in order to cause rotation of the shaft upon movement of the oscillating levers. The rotational speed of the output shaft can be infinitely varied by changing the throw of the oscillating levers.
Claims65
A transmission, comprising:
- an input shaft;
- at least one camming device coupled to said input shaft;
- at least two levers coupled to said camming device in a manner that causes said at least two levers to pivot in an oscillating manner upon rotation of said input shaft;
- at least one one-way clutch coupled to said at least two levers where movement of said at least two levers causes rotational movement of said at least one one-way clutch;
- and
- an output shaft coupled to said at least one one-way clutch, said at least one one-way clutch capable of causing rotation of said output shaft.
A transmission, comprising:
- an input shaft;
- at least two oscillating members, each pivotable about an axis and coupled to said input shaft such that rotation of said input shaft causes oscillation of said oscillating members;
- at least one camming device coupled to said at least two oscillating members to provide ripple free power from said oscillating members;
- at least one one-way clutch coupled to said at least two oscillating members;
- and
- an output shaft coupled to said at least one one-way clutch, said output shaft being driven by oscillation of said at least two oscillating members which in turn drives said one-way clutch to rotate said output shaft.
A transmission, comprising:
- an input shaft;
- an output shaft;
- at least one oscillator driven by said input shaft;
- at least two oscillator followers moveable by said at least one oscillator;
- at least two levers, each coupled to one of said at least two oscillator followers for movement therewith and each pivotable about a fulcrum;
- and
- at least two slide members, each coupled to one of said at least two levers for back-and-forth movement of said at least two slide members along with the movement of said at least two levers, said at least two slide members driving said output shaft;
- whereby translation of said at least two levers relative to said slide members varies the rate of rotation of said output shaft relative to said input shaft.
A transmission, comprising:
- a housing having a first wall and a second wall;
- an input shaft journaled through said first wall of said housing;
- an out put shaft journaled through said second wall of said housing;
- a concentric shaft slidably splined on said input shaft;
- a control slide fixedly coupled to said concentric shaft and being slidably guidable relative to said housing;
- at least one cam defining a cam surface, said cam surface being substantially parallel to said concentric shaft and fixedly secured to said concentric shaft;
- at least one biased cam follower longitudinally fixed relative to said concentric shaft;
- at least one lever rotatably coupled to each said at least one cam follower;
- biasing means for biasing said at least one cam follower into contact with said cam surface of said at least one cam;
- at least one selectively locatable, self-locking power take-off on each said at least one lever;
- and
- connection means for interconnecting said power take-off to said output shaft.
