20140323258 | EPICYCLIC ARRANGEMENTS AND RELATED SYSTEMS AND METHODS - System comprising an epicyclic arrangement. In some embodiments, the epicyclic arrangement can comprise: a first input element; a second input element fixed to an input drive shaft; a geared carrier that includes at least a portion that is disposed axially between the first and second input elements, the geared carrier being engaged with an output member; and planets associated with the geared carrier. Some embodiments of the present systems comprise a housing in which the epicyclic arrangement is disposed; and/or fluid contained within the housing. | 10-30-2014 |

20120220425 | METHOD OF CONTROLLING A CONTINUOUSLY VARIABLE TRANSMISSION - A method for controlling a continuously variable ratio transmission is described. The method may include controlling a continuously variable ratio unit (“variator”) having rotary input and output members through which the variator is coupled between an engine and a driven component, the variator receiving a primary control signal and being constructed and arranged to exert upon its input and output members torques which correspond directly to the control signal. The method may also include determining a target engine acceleration, determining settings of the variator's primary control signal and of an engine torque control for providing the required engine acceleration and adjusting the control signal and/or the engine torque control based on these settings, predicting a consequent engine speed change, allowing for engine and/or transmission characteristics, and correcting the settings of the control signal and engine torque based on a comparison of actual and predicted engine speeds. | 08-30-2012 |

20120142477 | CONTINUOUSLY VARIABLE RATIO TRANSMISSION - A multi-regime continuously variable ratio transmission has a transmission input shaft, a transmission output shaft, and a ratio varying unit having a rotating input and a rotating output, the rotational axes of the input and the output being coaxial. A shunt having first and second epicyclic gear sets is connected across the ratio varying unit. One gear set has an input driven by the input shaft and an input driven by one side of the ratio varying unit and the other gear set has an input from the first gear set and an input from one side of the ratio varying unit. The gear sets rotate about a common axis and are offset with respect to, and parallel to, the rotational axes of the input and output of the ratio varying unit. A clutch is operable to selectively connect the output of the second gear set to the output shaft. | 06-07-2012 |
