Abstract: The clutch control reversible transmission wheel system with bidirectional input and one-way output relates to a transmission structure, wherein the drive rotary direction of the input shaft of the wheel system with bidirectional input and one-way output is changed to make the direction of the output of the output shaft to be constant, which is characterized by releasing the connectable or releasable clutch device installed between transmissions of the wheel system with bidirectional input and one-way output, the output shaft is moved reversely when reversely driven.

Abstract: A foot-pedaling device with bidirectional pedaling for constantly driving a loading wheel train in the same direction, wherein the pedaling direction is selected by the riding pedaler according to the operating status of his/her muscles and joints, or through the different driving directional input, to provide different-speed-change- ratio output.

Abstract: An assembled transmission device with bi-rotating directional input and constant rotating directional output can be directly installed in pipe holes of a basic through hole pipe of a vehicle, so that a vehicle to be driven that is installed with the basic through hole pipe is easy to assemble and maintain.

Abstract: The torque transmission system for an aircraft engine permits a starter-generator to drive the engine on starting at a speed reducing ratio. Once the engine is running, the engine then drives the starter-generator also at a speed reducing ratio.

Abstract: A command assembly for controlling a splitter in a transmission allows shifting between first and reverse-low gears while the splitter is engaged without requiring the splitter to cycle during the shift. The command assembly creates a signal path for a split enable signal that keeps the transmission in the split mode as long as the transmission engages a low rail of a main drive box. By creating a separate signal path for the split enable signal when the transmission is operating in split mode, the splitter does not need to be cycled when the driver shifts between first and reverse-low gears.
