CATERPILLAR TRANSMISSION Russian patent published in 1994 - IPC

FIELD: transport engineering. SUBSTANCE: transmission connects a coupling engaged with an engine, the drive gear of a distributing reduction gear is mounted on the coupling shaft. Driven gears of the reduction gear are connected to toroidal gears which axles are made in parallel to the longitudinal axis of the caterpillar. The transmission has gear range reduction gears-doublers. The drive shafts of the reduction gears-doublers are connected to driven members of the toroidal gears. Each drive shaft has a freely mounted gear train, freely mounted forward and reverse movement gears connected to the shaft by a controllable gear clutch. Each driven shaft has a gear train and a gear freely mounted and connected by a controllable gear clutch, a brake and a main gear. The forward and reverse motion gears mate the gear train of the driven shaft. The gear train of the drive shaft mates the gear of the driven shaft. The transmission has a power take-off shaft. EFFECT: improved structure. 1 dwg
