Continuously variable transmission with uniform input-to-output ratio that is non-dependent on friction

An infinitely variable transmission comprising:

• A) at least one scotch yoke module comprising:
• a) a crank pin perpendicularly mounted on
• b) a crank pin collar having a non-circular orifice and sliding on
• c) a co-axial crank pin collar shaft having a matching non-circular cross-section, and the crank pin collar shaft is mounted perpendicularly on
• d) an auxiliary input shaft, such that a longitudinal axis of the crank pin is coplanar and parallel and at an offset distance to a longitudinal axis of the auxiliary input shaft, wherein the offset distance can be altered by displacing the crank pin by
• B) a crank pin displacement mechanism comprising:
• a. a sliding collar disposed co-axially with the auxiliary input shaft, with a feature preventing relative angular displacement between the sliding collar and the auxiliary input shaft while allowing relative translation,
• b. a link assembly comprising:
• i. a link having a first end and a second end, the first end connected to the crank pin collar by
• ii. a crank pin pivot pin, the second end connected to the sliding collar by
• iii. a sliding collar pivot pin, wherein an axial displacement of the sliding collar causes radial movement of the crank pin through the link assembly,
• c. at least one thrust bearing that is co-axially placed in contact with the sliding collar, such that an external force applied on the thrust bearing causes an axial displacement of the thrust bearing and the sliding collar with respect to the auxiliary input shaft, which alters the offset distance by moving the crank pin collar together with the crank pin along the crank pin collar shaft,
• d. a slotted rack holder comprising one or more racks, which is restricted to only move along a direction of a longitudinal axis of the one or more racks, and a crank pin slot for receiving the crank pin, with a longitudinal axis of the crank pin slot orthogonal to the one or more racks,
• B) an input shaft,
• C) at least one driving non-circular gear mounted on the input shaft and driving
• D) at least one driven non-circular gear mounted co-axially on the auxiliary input shaft, at a fixed orientation to the axis of the crank pin shaft and
• E) at least one rectifier module comprising:
• a. a pinion engaged with the one or more racks, and mounted on
• b. a pinion shaft through
• c. a computer-controlled clutch, a one-way bearing, or a ratchet mechanism;
• arranged such that a uniform rotation of the at least one driving non-circular gear via the input shaft, causes a non-uniform angular velocity of the auxiliary input shaft via the at least one driven non-circular gear, causing the crank pin to revolve around the auxiliary input shaft reciprocating the one or more racks substantially along a longitudinal direction of the one or more racks at a substantially constant velocity and slowing down briefly during direction reversal and accelerating to the constant velocity, where a magnitude of the reciprocation is proportional to the offset distance of the crank pin and the auxiliary input shaft, and the reciprocation of the rack causes an alternating rotation of the pinion and the rotation of the pinion is converted to a unidirectional rotation of an output gear, or output sprocket mounted on the pinion shaft via the computer controlled clutch, the one way bearing or the ratchet mechanism.
