摘要:
A multiple speed power transmission comprises: an epicyclic gearing assembly comprising first, second, third, and fourth rotating members with linearly related speeds; a double pinion planetary gear set with grounded carrier and input driven sun gear; two brakes; four clutches; and specified interconnections. The brakes and clutches are operated in combinations of two to produce eight forward speed ratios and at least one reverse speed ratio.
