SHAFT-PLANETARY HYBRID TRANSMISSION Russian patent published in 2023 - IPC F16H3/00 B60K17/12 B60K6/547 F16H3/72 F16H37/04 

FIELD: mechanical engineering.

SUBSTANCE: shaft-planetary hybrid transmission contains a multi-mode shaft gearbox, including an input shaft, with the possibility of its connection with the engine. It also has at least two intermediate shafts parallel to the input shaft, an output gear mechanism, a gearbox output shaft parallel to the intermediate shafts, gears and gear shift clutches, and disc friction controls. A simple summing planetary gear mechanism with clutch function is installed at the entrance to the gearbox. Its sun gear is connected to the input shaft of the gearbox. The carrier is equipped with brake T₀ and is configured to communicate with the said engine. The epicycle is equipped with brake T₁ and is configured to communicate with an additional motor. At the gearbox output, an additional gearbox is installed in the form of a controlled stepped planetary mechanism based on simple planetary gear sets, the sun gears of which are combined and connected to the gearbox output shaft. The epicycle of the first row and the carrier of the subsequent rows are combined and brought out as output shaft X. The carrier of the first row is equipped with brake T_R. The epicycle of each subsequent row is equipped with brake - T₂, T₃,…, and the epicycle of the last row is connected with output shaft X indirectly through clutch - C₃ or C₄.

EFFECT: improved performance of the transmission and the vehicle as a whole.
