VEHICLE TRANSMISSION Russian patent published in 1999 - IPC

FIELD: mechanical engineering; drive of vehicle driving wheels or steering mechanism. SUBSTANCE: transmission of wheeled-crawler vehicle has input reduction gear, clutch, controlled sleeves, gearbox, final drive, side step-down reduction gears, controlled hydraulic motor and hydraulic pump, and planetary gear trains. Driving bevel gear is connected by controlled sleeve with hydraulic motor and is in meshing with two driven bevel gears. One or both driven bevel gears can be connected with one of axle-shafts by second controlled sleeve. Planetary gear trains are installed between driven shaft of final driven and side step-down reduction gears. First members of planetary gear trains are installed on driven shaft of final driven, second members are connected through gear drive with axle-shafts of driven bevel gears, and third members are connected with driving shafts of side step-down reduction gears. EFFECT: increased utilization factor, enhanced reliability and longevity, increased power output of vehicle without use of special means. 1 dwg
