Abstract
Abstract Power is transmitted by a planetary and hydraulic assembly which has one input shaft, two output means, and two reactions. While one output means is increasing its speed, the other output means is simultaneously decreasing its speed, and the ratio of the maximum speed of one output means to its minimum speed is substantially the same as the ratio of the maximum speed of the other output means to its minimum speed. This characteristic of speeding up one output means while the other slows down is used over and over again by shifting the final output from the point where one of the output means is going at maximum speed to the other output means when it is going at minimum speed, thus going through this cycle again and again. The power transmission therefore connects successively the final output drive to one output member of the planetary assembly and then to the other output member of the planetary assembly, and then back to the first output member of the planetary assembly at a different ratio from the previous connection, and so on, and this can be done because these output means continually increase and decrease their speeds.

A method of operating a transmission of the type having a planetary gear assembly with a rotary input member, a pair of rotary reaction members, and a pair of rotary output members, said transmission also having first and second fluid pump-motors hydraulically connected together, each able to serve as a pump at some times and as a motor at other times, one serving as a pump while the other serves as a motor and vice versa, said first pump-motor being kept at constant stroke and being connectable in alternation through first and second reaction gear trains to each of said rotary reaction members, said second pump-motor always being connected operatively to said rotary input member, and a series of output gear trains of overlapping ratios, a plurality for each said rotary output member, a main output shaft, and clutch means for connecting said main output shaft to each said rotary output member through a said gear train, comprising the steps of:
Claim 491
Dependent Claim
29 words
The method of claim 90 characterized by a constant ratio between the maximum and minimum speeds of said main output shaft for every one of said output gear trains.
Claim 492
