METHOD AND SYSTEM FOR CRAWLER CARRIER BODY STABILISATION Russian patent published in 2013 - IPC B60G17/04 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry. Proposed system comprises running gears with drive and road wheels, controlled hydraulic system, hydraulic pump, intake and delivery lines, hydropneumatic accumulator, hydraulic booster, actuator and control unit. System power part is composed by independent units arranged inside crawler machine road wheels and furnished with hydraulic radial piston pump. Pump body is built in balancer bulk shaft that doubles as road wheel support. Pump shaft engages via hub with road wheel rim. Hydraulic pump is furnished with flat hydraulic control valve with inlet line built-in balancer body and communicated with delivery line connected with hydropneumatic accumulator and actuator. Delivery line extends through two-position solenoid with hydraulic booster, switchboard connected with hydraulic line and safety valves. Said valves serve to contrail the system operation. Aforesaid actuator is composed by a controlled single-vane hydraulic actuator with its body accommodate inside carrier body. Proposed method consists in creation of stabilising forces to act on carrier body from suspension side in motion. Energy for creation of said forces results from road wheel rotation kinetic energy originated in interaction with caterpillar chains. Said energy is transformed in working fluid pressure energy. It is accumulated and used in cushioning system actuators.

EFFECT: better stabilisation, perfected design.
