MULTI-PURPOSE TRACKED UNDERCARRIAGE Russian patent published in 2011 - IPC B62D11/14 F41H7/00 

FIELD: transport.

SUBSTANCE: invention refers to transportation equipment. Multi-purpose tracked undercarriage includes housing, caterpillar drives, suspension with six lower track wheels, movement control compartment, engine compartment, internal combustion engine of liquid cooling with high speed shaft, input reduction gear, and the appropriate external final drives for each caterpillar drive. Internal combustion engine is installed with its longitudinal axis perpendicular to undercarriage longitudinal axis. One end of high speed shaft is kinematically connected to fan of cooling system the radiators of which are located on continued longitudinal axis of the engine. The other end of shaft is kinematically connected to the appropriate external final drives for each caterpillar drive so that transmission of rotary moment to each of those is performed in two flows. The first flow being the main electric flow consists of traction alternator and traction electric motor. Input shaft of alternator is connected through switching mechanism and input reduction gear to which mechanical energy accumulator can be selectively connected in its turn with remote control. The second flow is additional flow transmitting mechanical energy, composed of accumulator, central differential adder of rotary moments, to which there can be selectively connected is high speed shaft of internal combustion engine, transfer box and then to external differential adders. The main flow from traction electric motor is supplied to adders. Control as to connection of additional flow for reinforcement of rotary moment of each drive wheel of caterpillar drive remotely and selectively as to time.

EFFECT: creation of multi-purpose undercarriage allowing to use the engine with lower power and to reduce the volume of one-time fuel filling.
