ABSTRACT:
A planetary gear transmission typically for use on automobiles has first, second, and third planetary gear trains arranged coaxially with each other and each having elements including a sun gear, a carrier, and a ring gear. Two of the elements of each of the first, second, and third planetary gear trains are directly or disengageably coupled to elements of the other planetary gear trains between input and output members. The elements of the first, second, and third planetary gear trains are corotatably coupled into first, second, third, fourth, and fifth rotational members the first, second, and fifth rotational members being coupled to the input member, the fourth rotational member being coupled to the output member. The planetary gear transmission also has a separating clutch disposed between the elements of the second rotational member, for disengageably connecting the elements of the second rotational member.
