Title:
TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2009/092216
Kind Code:
A1
Abstract:
A transmission includes an input shaft(IP), an output shaft(OP),a single planetary
gearset(SP), a compound planetary gearset(CP), shifting elements(C1,C2,C3,B1,B2),
a central supporter(CS) and a housing(H). The single planetary gearset is arranged
before the compound planetary gearset, and all the shifting elements are positioned
between them, which has compact arrangements, and can reduce the power transmission
length. The transmission also includes an one-way clutch(OWC) acted on the compound
planetary gearset. When the transmission shifts to the first speed stage, the
first clutch (C1) and the one-way clutch are operated, and the power istransferred
from the input shaft to the output shaft via the single planetary gearset and the
compound planetary gearset, and when the first speed stage is shifted to the second
speed stage, only the first brake(B1) should be operated to engage, thereby it
can reduce the frequency of operating the shifting elements and the shifting
time in low speed stage.
