Multi-Speed Tranmission

摘要

A multiple speed power transmission including: an input shaft, an output shaft, a first gearing assembly imposing a fixed linear speed relationship among five shafts, a second gearing assembly imposing a fixed linear speed relationship among three shafts, two clutches, and four brakes capable of producing nine forward speed ratios and one reverse speed ratio when clutches and brakes are applied in combinations of two.

1. A transmission comprising:
a first gearset selectively establishing a reverse speed relationship between an input and a first shaft; a second gearset selectively establishing a proportional speed relationship between the first shaft and a second shaft; a third gearset fixedly establishing a linear speed relationship among the input, the second shaft, and the first shaft; and a fourth gearset fixedly establishing a linear speed relationship among the first shaft, a third shaft, and an output.
