AUTOMOTIVE TRANSMISSION Russian patent published in 2012 - IPC F16H3/93 

FIELD: transport.

SUBSTANCE: invention relates to automated transmissions with gear shifting under load. Automatic transmission contains input shaft, output shaft parallel to input shaft, the first and the second transfer shaft, intermediate shaft each one of which is parallel to input shaft. Driveline also contains drive gears located on input, output. Transfer and intermediate shafts, the first, the second, the third and the fourth clutch couplings. Drive gears provide the first, the second, the third and the fourth front drive path from input shaft to output shaft. Gear ratio between input shaft and output shaft is increasing from the first to the fourth front drive path. The first clutch coupling connects input shaft and output shaft along the first or the third drive path through transfer shaft and drive gears located on the intermediate shaft. The second clutch coupling connects input shaft and output shaft along one of the second drive path through the second transfer shaft and drive gears located on the intermediate shaft and the forth front drive path. The third clutch coupling is for establishing the first or the third front drive path when the first coupling is working. The fourth clutch coupling is for establishing the second or the fourth front drive path when the second coupling is working.

EFFECT: compact design.
