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 9):
A constantly variable speed transmission comprising:\n an input shaft driven by an engine flywheel; a drive shaft for driving the wheels of a vehicle; at least two fluid couplings, each fluid coupling comprising: an impeller and a turbine, each impeller and each turbine having vanes, each impeller controlled by the input shaft, each turbine configured to rotate in response to rotation of the respective impeller, each turbine connected to an output shaft, the output shaft configured to rotate with rotation of the respective turbine, each output shaft having odd and even output gears, the odd and even output gears placed in an alternating arrangement on the output shafts, the odd and even output gears transferring force from the respective fluid coupling to the drive shaft to drive the wheels of the vehicle; and a control module, the control module configured to adjust a distance between the impellers and turbines.
