Patent attributes
Vehicular transmission systems includes a frame, a wheel drive sprocket associated with a wheel, a main drive sprocket mounted on the frame, a transmission member rotationally coupling the drive sprockets, a pedal slider coupled to the frame and which swings forward and rearward, and a drive mechanism including an overrunning clutch system connected to the main drive sprocket. A power link is connected at a first end region to the pedal slider and at a second end region to the clutch system. Forward movement of the pedal slider causes movement of the power link and rotation of the clutch system which causes rotation of the main drive sprocket and the wheel drive sprocket resulting in rotation of the wheel. The clutch system includes a drum over which the power link passes, and which has a circular portion and a fin extending radially outward therefrom.
