Title:
TRANSMISSION STRUCTURE
Document Type and Number:
Japanese Patent JP2023014983
Kind Code:
A
Abstract:
To provide a transmission structure which can smoothly switch a first HMT transmission state for inputting power from a drive source and an HST to planetary first and third elements, and outputting it from a planetary second element, and a second HMT transmission state for inputting the power from the drive source to the second element, and outputting it from the first element.SOLUTION: In a transmission structure of this invention, either of input-side/ output-side clutch mechanism pairs is brought into a dual transmission state after a time point at which a drive rotation force arrives at a first/second gear-stage shift-up start speed up to a time point of a finish of the shift-up, a first clutch mechanism of the other of the input-side/output-side clutch mechanism pairs is transited to a release state while making a friction plate slide during a shift-up dual transmission state, and a second clutch mechanism of the other of the clutch mechanism pairs is brought into an engagement state while making the friction part slide.SELECTED DRAWING: Figure 5
