Transmission structure

The invention provides a transmission structure. The transmission structure smoothly switches between a first HMT transmission state in which power from a drive source and an HST is input to first and third elements of a planet and output from a second element of the planet and a second HMT transmis...

Zusammenfassung:	The invention provides a transmission structure. The transmission structure smoothly switches between a first HMT transmission state in which power from a drive source and an HST is input to first and third elements of a planet and output from a second element of the planet and a second HMT transmission state in which power from the drive source is input to the second element and output from the first element. A transmission structure according to the present invention puts one of an input-side clutch mechanism and an output-side clutch mechanism into a dual transmission state during a period from a point in time at which a drive rotational power reaches a first/second upshift start speed to a point in time at which an upshift ends, and puts one of the input-side clutch mechanism and the output-side clutch mechanism into a dual transmission state during the upshift dual transmission state. A first clutch mechanism of the other of the input-side and output-side clutch mechanism pairs is shifted to a released s
