CRAWLER VEHICLE TRANSMISSION Russian patent published in 2007 - IPC B62D11/10 

FIELD: transport engineering.

SUBSTANCE: invention relates to single-flow transmissions of transport and traction crawler vehicles with final drives. Transmission contains two main planetary final drives whose input shafts are coupled with engine through auxiliary gearbox and matching reduction unit, and output shafts are coupled with driving wheels of vehicle through two similar final drives. Transmission contains two auxiliary planetary gearboxes coupling driven gear wheel of matching reduction unit with driving shafts of main final drives. Each auxiliary gearbox consists of three-member planetary mixed-engagement mechanism in which epicyclic gear wheel is rigidly connected with driven gear wheel of matching reduction unit. Carrier is rigidly connected with driving shaft of main final driven. Sun gear is furnished with independently controlled normally open friction brake. Two main members of three-member planetary mechanism, for instance, epicyclic and sun gears, are intercoupled by normally open friction clutch.

EFFECT: provision of turning in any direction at minimum radius, enlarged speed and power ratings of vehicle.
