COAXIAL GEARBOX WITH TWO CLUTCHES Russian patent published in 2020 - IPC F16H3/93 

FIELD: transport machinery.

SUBSTANCE: invention relates to automotive industry. Coaxial gearbox with two clutches comprises input and output shafts and parallel countershaft with six pairs of gears installed on them. Solid and tubular input shafts are located one inside the other, on the intermediate shaft there are two installed freely installed gears, which are combined into the unit, which can be connected to the intermediate shaft by means of the clutch, and one of them is engaged with freely installed gear of the integral input shaft, and other is engaged with freely installed on output shaft gear, which can be connected to it by means of clutch. On the output shaft of the latter there is a gear which can be connected to it by means of a clutch. On the integral input shaft there is a clutch engaged connecting two gears engaged with gears, which are combined into a unit and installed on an intermediate shaft. Coupling connecting with output shaft and gear fitted thereon is combined with reverse gear engagement coupling. Sun gear fixed on the output shaft and the last gear of the output shaft with the carrier of the planetary low-multiplier having the coupling of the higher or lower range connection, rigidly connects the clutch, which is installed separately.

EFFECT: simplified design of the gear box.
