ABSTRACT:
A multi-range, dissipative, infinitely variable ratio transmission has a planetary gearset with at least four distinct gear components including an input gear, an output gear and a pair of independently rotatable gears; a first hydroviscous brake connected to one of the rotatable gears; a second hydroviscous brake connected to the other of said rotatable gears; and a circuit including brake operating units for selecting which of said brakes is operable and for controlling the amount of slip of the operable brake in order to cover all combinations of input and output speed within their respective ranges with minimal slip of a hydroviscous brake to maximize efficiency of the transmission.
