FIELD: mechanical engineering.
SUBSTANCE: hydrostatic power split transmission mechanism is in drive connection with the sun gear of the first planetary gear and the sun gear of the second planetary gear. The carrier of the first planetary gear is connected to the carrier of the second planetary gear. The carrier of the first planetary gear is connected to the sun gear of the third planetary gear. The carrier of the third planetary gear is in transmission connection with the input main shaft. The first clutch may couple the input main shaft to the gear of the second planetary gear for forward rotation. The second clutch may couple the input main shaft to the gear of the second planetary gear for reverse rotation. The brake may block the gear of the first planetary gear. The drive disk of the third clutch is in transmission connection with the gear wheel of the third planetary gear. The drive plate of the fourth clutch is in transmission connection with the sun gear of the third planetary gear. The third clutch driven disk and the fourth clutch driven disk are connected to the output main shaft.
EFFECT: wide range of speed adjustment is achieved, reducing gear shift time.
