US 5,472,388 A · Rotary to stepless motion converter

Abstract

A rotary to stepless motion converter that functions as a vehicle linear transmission (1). The converter consists of an upper rotating disc (11A) and lower rotating disc (11B) that are horizontally displaced and enclosed by an upper disc cover (15A) and a lower disc cover (15B). Between the two discs is located a counter-rotating shaft (14) that has attached a front transferrer wheel (13A) and a back transferee wheel (13B). The shaft front is attached to a vehicle engine (7) and the back to a drive shaft (2). When the front wheel (13A) is rotated, and the discs (11a), (11B) are centered, the two wheels remain stationary. When the lower disc (11A) moves in a +Y direction and the upper disc (11B) in a -Y direction, the two wheels move in a +X direction. Conversely, when the discs move in opposite directions, the two wheels move in a -X direction. The converter allows speed changes that are not detectable because the changes are continuous without momentary reductions in speed.
