This invention discloses uninterrupted shifting in transmissions with the use of controlled rotation to achieve desired profile for input to output ratio, thereby eliminating synchronized clutch. Controlled rotation achieved using non-circular gears or Geneva pin and slot wheel mechanism with a customized path for the slot, is used to achieve multiple speed/infinitely variable transmission ratios and/or to transition from one transmission ratio to another. The transition happens over multiple rotations of the input making it highly suited for high torque applications. Since it is not using sprag or one way bearing engine breaking can be achieved. Infinitely Variable Transmission offers steady and uniform output for a steady and uniform input. With co-axial input and output, using planetary gear system, the output can be made continuous from forward to reverse. Multi-Speed uninterrupted shifting is achieved without the need for synchronizers and using a dog clutch or similar device.

Provided is a support apparatus including a drive motor, a link mechanism that, by transmitting motive power output from the drive motor, is extendable and contractable in response to the motive power, and a pair of rotating bodies that act as a variable speed mechanism that outputs the motive power to the link mechanism by a reduction ratio according to an attitude of the link mechanism. At least part of the link mechanism forms a trapezoidal link mechanism.

This invention is an all gear continuously variable transmission that is non-dependent on friction. It can me be used in high torque applications. It offers a steady and uniform output for a steady and uniform input. It allows a co-axial input and output thereby by using a planetary gear system the output can be made continuous from forward to reverse. This uses a “scotch-yoke” mechanism to convert rotational motion to a linear reciprocating motion. The linear distance of this reciprocating motion-“stroke” is changed by altering the crankpin location of the scotch-yoke mechanism. This reciprocating motion is converted to a rocking motion by using a “rack and pinion” and later converted to a unidirectional motion via a One-Way-Bearing. A set of non-circular gears are used to achieve a steady and uniform output. It employs a very simple mechanism to change the ratio between the input and output of the transmission.
