Abstract:
The variable speed transmission uses multiple fluid couplings to provide a sturdy, durable variable output ratio transmission by using hydraulic fluid to vary the output. Each fluid coupling has an independent output shaft driven by the respective fluid coupling turbine. Output shafts drive alternate gears (i.e., first and third at a first fluid coupling and second and fourth at a second fluid coupling). This configuration alternates gear shifts between the fluid couplings allowing the next gear up or down to be engaged before disengaging the current gear, for uninterrupted gear changes in both up and down shifting. A fifth gear would be driven by a gear connected to the fluid coupling input shafts. Gears could be engaged with hydraulic clutches or syncromesh gears. This combined with variable slip fluid couplings allows for better torque and control.

Claim (Index 1):
A variable speed transmission using hydraulic fluid, the transmission comprising:\n an input shaft driven by an engine flywheel; a drive shaft for driving wheels of a vehicle; a first fluid coupling comprising:\n a first turbine and a first impeller, the first turbine configured to rotate in response to rotation of the first impeller, the first impeller controlled by the input shaft, the first turbine connected to and configured to drive a first output shaft, the first output shaft configured to drive a first set of alternating gears; \n a second fluid coupling comprising:\n a second turbine and a second impeller, the second turbine configured to rotate in response to rotation of the second impeller, the second impeller controlled by the input shaft, the second turbine connected to and configured to drive a second output shaft, the second output shaft configured to drive a second set of alternating gears, one of the first and second set of alternating gears transferring force from a corresponding turbine to the drive shaft to drive the wheels of the vehicle; and \n a control module, the control module configured to adjust a distance between the impeller and turbine in each of the fluid couplings.
