Abstract: The invention relates to a continuously variable transmission (CVT) system, governed by an inertial mechanism that provides an additional degree of freedom, conferring dynamic properties on the transmission. The complete system includes three distinct subsystems. The first subsystem transforms the rotating movement from the driving system into a movement with oscillating angular speed and regulates the amplitude of said movement. The oscillating rotation at the output of the first subsystem is used to drive the second subsystem, which acts as a regulating element by means of the inertial mechanism. In this manner, the second subsystem acts as a torque-regulating element, providing a signal representing the oscillating angular speed at the output shaft thereof. The oscillating rotation at the output of the second subsystem is rectified in the third subsystem, thereby providing a signal representing angular speed in a single direction of rotation at the output shaft.

Abstract: The present invention relates to transmission systems and changing gear ratios within power transmission systems. In particular, the present invention relates to a positive displacement variable speed transmission. The transmission includes one or more drive gears which orbit, rotate, and which translate radially to change the size of the orbital path. The change in the orbital path increases or decreases the linear velocity of the drive gears which engage one or more driven gears and transfer the changed linear velocity in the form of a gear ratio change. The driven gears are also radially movable and movement of the driven gears is synchronized with the radial movement of the drive gears to maintain substantially constant engagement between gear ratios change. Thus, as the drive and driven gears can slide or step radially to any location within a range of positions, gear ratio changes can be made in very small increments.

Abstract: The system is comprised of three sub-systems. The first sub-system has an actuation lever (P) which can rotate about an axis (E1) to displace excentrically the Second Sub-system with respect to the Third by a predetermined angle circumferentially about a toothed wheel (R1), a toothed fluted wheel (R2) or fluted cross or cross with sliding torkes, and gear carrying shafts passing therethrough. The grooved wheel (R2) rotates a fixed transmission relationship with respect to the rotation of the input shaft. The second sub-system transforms and divides the input power for the primary shaft into powers which are transmitted to various secondary shafts (E3, E4) characterized by oscillating angular speeds and torkes. The third sub-system composes the powers transmitted by the secondary shafts by means of a epicyclic train (T1) into an output power. The resulting output motion is proportional to the eccentricity angle of the first sub-system with respect to the third sub-system.

Abstract: A transmission utilizes oscillating torque to vary the mechanical power transmitted to a load. An arm assembly is rotatably coupled to a frame. At the ends of the arms are eccentric masses, rotatably coupled thereto. An input shaft rotates the masses about the ends of the arms. The rotating masses produce an oscillating torque that causes the arms to oscillate. The arms are coupled to an output assembly. The output assembly utilizes one way clutches, with one clutch reversed relative to the other clutch. The one way clutches convert the bidirectional rotation of the arms to unidirectional rotation for the load. The output speeds of the transmission are controlled by providing at least two side by side rotatable masses and varying the phase of one of the masses relative to the other mass. Varying the phase changes the center of gravity of the masses, thereby affecting the torque applied to the arms.

Within each planetary gear is mounted an over-rolling clutch. The planet gear is free to rotate about its raceway in one direction and is locked from rotation in the opposite direction. The shaft mountings for each planetary gear are suitably journalled in a carrier ring rotatably mounted within the housing. An internal gear, integrally mounted within the output housing, meshes with the planetary gears and is driven by them.

The eccentric system is continuously positionable so as to increase the rotation of the input sun gear from a one-to-one ratio up to the maximum designed output.
