TRANSMISSION AND WORKING VEHICLE
Document Type and Number:
WIPO Patent Application WO/2015/072179
Kind Code:
A1
Abstract:
A first clutch is configured to switch between the connection and disconnection of a second carrier and a housing. The first clutch is disposed between a first planetary gear mechanism and a second planetary gear mechanism in the axial direction. A second clutch is disposed between the second planetary gear mechanism and the first planetary gear mechanism in the axial direction. The second clutch has a smaller outer diameter than the first clutch. A first piston is configured so as to engage the first clutch by pressing the first clutch. A return spring is disposed on the outside radially of the second clutch so as to be adjacent to the first clutch in the axial direction. The return spring presses the first piston so that the first piston moves away from the first clutch.
