  • Power split transmission system and vehicle
    Patent number: 11982341
    Abstract: A hydrostatic transmission mechanism of the power split transmission system is in driving connection to the sun gear of the first planetary gear train and the sun gear of the second planetary gear train. The planetary carrier of the first planetary gear train is connected to the planetary carrier of the second planetary gear train. The planetary carrier of the first planetary gear train is connected to the sun gear of a third planetary gear train. The driving plate of a third clutch is in transmission connection to the gear ring of the third planetary gear train. The driving plate of a fourth clutch is in transmission connection to the sun gear of the third planetary gear train. Each of the driven plate of the third clutch and the driven plate of the fourth clutch is connected to an output main shaft.
