Title:
WORK VEHICLE
Document Type and Number:
Japanese Patent JP2021046904
Kind Code:
A
Abstract:
To smoothly transmit power of a continuously variable transmission during gear shifting, etc. in a work vehicle including the continuously variable transmission continuously shifting a driving force and a planetary gear shifting mechanism shifting the driving force shifted by the continuously variable transmission.SOLUTION: A work vehicle includes: a prime mover; a travelling device; a continuously variable transmission continuously shifting a driving force transmitted from the prime mover; a planetary gear shifting mechanism shifting the driving force shifted by the continuously variable transmission; a clutch mechanism that can be switched between a connection state of connecting to a travelling transmission shaft transmitting the driving force shifted by the planetary gear shifting mechanism to the travelling device and a disconnection state of preventing connection to the travelling transmission shaft; and an automatic transmission section starting a switching operation for switching the clutch mechanism from the connection state to the disconnection state before the driving force output from the continuously variable transmission reaches an automatic transmission condition.SELECTED DRAWING: Figure 2
