ABSTRACT:
A mechanical assembly is operable as a variable speed transmission. The output shaft has a rotational force at speeds variable from an input applied to an input shaft. The mechanical assembly is a transmission device using a "positive traction" effect with a differential using a speed control (control shaft or hydraulic device) of relatively small controlling power to control transmission of power from the input shaft to the output shaft. Planetary gearing at a two-to-one ratio is used to convert the speed and direction supplied by the speed control to the output axle. The power input is applied to a differential carrier by a shaft mounted opposite of and collinear to the output axle. This eliminates the ring gear and pinion normally required. The carrier of a planetary gearing is used for speed control and is connected to the control shaft by a one-to-one ratio. The control shaft rotates in direct proportion to the output shaft and the output shaft maintains the same relative position of rotation as the control shaft. The speed of the output shaft can be varied or held at any speed from zero to the speed of the input power supply.
