Abstract
A shiftable transmission drive with assured input-output relationship includes a drive motor-transmission mechanism wherein a drive motor drives an output shaft at different rates through a shiftable transmission, and wherein the output shaft is always connected with the drive motor through the shiftable transmission. The output shaft is thus always under control and its position precisely known. The shift position of the gears is known. Shifting is directed at predetermined positions by a microprocessor when the transmission is stopped or at low speeds of rotation. The drive is a direct drive or alternatively a gear ratioed drive.
