AUTOMOTIVE HYBRID TRANSMISSION Russian patent published in 2011 - IPC F16H3/44 B60K6/365 B60W20/00 B60W10/10 B60L11/14 

FIELD: transport.

SUBSTANCE: hybrid transmission comprises two planetary gear sets. Planetary gear set elements are coupled with drive engine via two all-purpose electrical machines and, via output links, with torque. Controlled friction couplings couple links of planetary gear sets with housing and between them. First universal electrical machine engages with crown gear of the first planetary gear set and, via first controlled coupling, with input shaft while, via second controlled coupling, it is engaged with pinion frame of secondary planetary gear set. Second planetary gear set crown gear is engaged via third controlled coupling with housing. Second all-purpose electrical machine is directly engaged with sun gear of both planetary gear sets and, via fourth controlled coupling, with housing.

EFFECT: improved kinematics.
