VEHICLE GEARSHIFT AND STEERING GEAR Russian patent published in 2004 - IPC

FIELD: transport engineering; crawler vehicle transmissions.

SUBSTANCE: proposed gear contains two hydraulic machines 1, 2 which are hydraulic interconnected, one of machines being adjustable. Drive shaft 4, countershaft 5 and output shafts 6 and 7 are mechanically connected with hydraulic machines. Gearbox 10 has controllable clutches 11-14 and additionally shaft 48 with gears. Two planetary differentials 8, 9 are connected with driven 4 through gearbox 10. Sun gears 20, 21 are mechanically connected with hydraulic motor 1. Gear 20 is connected through additional gear 22. Epicyclic gears 23, 24 of planetary differentials are connected with countershaft 5, and carriers 18, 19, with output shafts 6, 7.

EFFECT: enlarged functional capabilities at small overall dimensions and mass, facilitated steering and high efficiency.
