FLOATING VEHICLE TRANSMISSION Russian patent published in 2004 - IPC

FIELD: transport engineering.

SUBSTANCE: invention relates to amphibian vehicles and rafting equipment, and it can be used for designing floating crawler amphibian vehicles. Proposed transmission contains gear reduction unit, planetary final drives of crawler propulsion unit and transfer case. The latter includes bevel gear train, hydraulically-controlled normally-open friction clutches and output shafts connected with propeller shafts of drives of water propulsion unit propellers. To provide alternate or simultaneous transmission of torque to final drives of crawler propulsion unit drive and drive of water propulsion unit propellers, input shaft f transfer case is installed in parallel to rear output shaft of gear reduction unit. Said shaft is arranged at other side of longitudinal axis of vehicle at a distance providing angle of tilting of propeller shaft connecting said shafts within o and 20^o. Output shafts of transfer case are made square to output shaft of gear reduction unit. Transfer case in made in two-body casing. First casing detachably mounted on second one, accommodates input shaft with bevel train and second casing accommodates output shafts with drive.

EFFECT: provision of minimum overall dimensions of seta and transmission as a whole.
