TRANSMISSION ASSEMBLY AND AGRICULTURAL VEHICLE WITH SUCH TRANSMISSION ASSEMBLY Russian patent published in 2018 - IPC F16H3/66 F16H37/04 

FIELD: agriculture; mechanical engineering.

SUBSTANCE: invention relates to transmission assembly (3) for an agricultural vehicle. Transmission assembly comprises three planetary gears (10, 20, 30) and coupling systems (11, 12, 21, 22, 31, 32), entering into multi-speed transmission mechanism (6) into seven power-shift stages (L₁…₇) that can be switched, and a transfer mechanism (7) connected thereto. To set the next lower or next higher gear ratio (i) of transmission assembly (3) in multi-speed transmission mechanism (6), no more than two coupling systems (11, 12, 21, 22, 31, 32) are required to actuate.

EFFECT: higher reliability.
