HIGH-PERFORMANCE INDUSTRIAL TRANSMISSION Russian patent published in 2021 - IPC F16H3/66 

FIELD: mechanical engineering.

SUBSTANCE: group of inventions relates to the field of mechanical engineering. The high-performance transmission comprises a crankcase, primary shaft, secondary shaft, intermediate shaft, four-speed planetary gear, selectively transmitting power from the primary shaft to the intermediate shaft and from the intermediate shaft to the secondary shaft. The four-speed planetary transmission additionally comprises a front planetary section with a pair of front planetary gears designed to selectively transfer power from the primary shaft to the intermediate shaft, and a rear planetary section with a pair of rear planetary gears designed to selectively transfer power from the intermediate shaft to the secondary shaft. A pair of rear planetary gears contains a race that connects the planetary gear carrier of one of the pairs of rear planetary gears to a ring gear from the other pair of rear planetary gears. The second embodiment of the device includes front and rear sets of clutches, and a transmission control system.

EFFECT: improved performance and simplified transmission design.
