ABSTRACT:
A planetary gear system has seven members rotatable relative to one another, one stationary member, and five selective engaging devices each disposed between two of the members. Each member contains one or more of elements which are input and output elements, a stationary element, and a plurality of active elements, such as sun gears, ring gears, and planet carriers, constituting a planetary gear arrangement connected between the input and output elements for providing a plurality of forward gear ratios and at least one reverse gear ratio. With the eight members and the five selective engaging devices, the planetary gear system makes it possible to attain desired gear ratio values for all the speeds.
