OFFSET SHAFT- PLANETARY GEAR BOX Russian patent published in 2010 - IPC F16H37/08 

FIELD: machine building.

SUBSTANCE: eight step offset shaft- planetary gear box consists of 6 gears, of elementary three-link planetary mechanism, dual coupling and two clutches of gear shift. Input shaft (2) and primary shaft (3) are coaxially arranged in supports of case (1) of the gear box. Secondary shaft (4) is mounted parallel to coaxial shafts (2) and (3), while coaxially to shaft (4) there are located output shaft of carrier (5) and output shaft (6) of the assembly. Tubular shaft (7) with gear (8) engaging gear (9) is mounted of primary shaft (3). Block of gears (9) and (10) is freely assembled on secondary shaft (4) whereon there is also freely installed gear (11). Gear (10) of the block engages gear (12) secured on primary shaft (3). Gear (13) is also secured on primary shaft (3) and engages gear (11) of secondary shaft (4). Carrier (14) is fixed on output shaft (5), while sun gear (15) is fixed on secondary shaft (4). Epicyclical gear (16) with tubular shaft (17) is connected with tooth crown (18). Sun gear (15) engage satellites (19) arranged on axles of carrier (14); the satellites are engaged with epicyclical gear (16). Two-position tooth crown (20) of carrier (14) is secured on output shaft of carrier (5); while three-position tooth crown (21) is mounted on output shaft (6). Three-position clutch (22) is installed on tooth crown (21) and is movably connected with slider (23) with fork; double-sided tooth crowns (24) are assembled on the slider; with their external crown they engage tooth crown (25) of the assembly case (1). Three position clutch (26) is mounted on secondary shaft (4) between the second and the third row of gears. Driven disks (27) of left coupling are arranged on primary shaft (3), while driven disks (28) of the right coupling are arranged on tubular shaft (7).

EFFECT: expanded operational functionality of vehicle.
