Multispeed power transmission |
摘要 |
A multispeed transmission has a planetary gear arrangement (26) and two pair of countershaft gears (28-34). The countershaft gears are drivingly connectable between the output of the planetary gear arrangement and the output shaft (36) of the transmission. One pair (28,32) of the countershaft gears provides a rotating reaction for the planetary during one speed ratio and a reduction ratio during at least one other speed ratio. The other pair (30,34) of countershaft gears provides a reduction ratio from the planetary during the one speed ratio and a single reduction ratio between the transmission input and the transmission output in at least one other speed ratio. The planetary transmission is controlled by clutches (14-20) and brakes (22,23) to establish a reduction ratio, a direct drive and an overdrive ratio. |
