POWER TRANSMISSION SYSTEM Russian patent published in 2018 - IPC B60K6/445 B60K6/547 F16H48/00 

FIELD: machine building.

SUBSTANCE: invention relates to hybrid vehicle transmission systems. Power transmission system (TM1) includes first differential mechanism (10) connected to the engine and second differential mechanism (20). First differential mechanism includes a first rotating member coupled to the motor, a second and a third rotating member. Second differential mechanism includes a fourth rotating member coupled to the second rotating member, a fifth rotating member connected to the first rotating electric machine (MG1), a sixth rotating element, which is an output element of the second differential mechanism. Power transmission system further includes first clutch (CL1), brake (BL1) and second clutch (CLr). First clutch is configured to form a pair for releasably connecting two elements from the first, second and third rotating members. Brake is configured to form a pair for releasably connecting the third rotating member to the fixed member. Second clutch is configured to form a pair for releasably connecting the third rotating member to the fifth or sixth rotating members.

EFFECT: increase in economy and reliability is achieved.
