PNEUMATIC AND TORSION BAR SUSPENSION OF TRACK-TYPE VEHICLE Russian patent published in 2015 - IPC B60G17/00 

FIELD: machine building.

SUBSTANCE: system comprises torsion bars and pneumo-hydraulic springs of track rollers, and the related control system. The control system is fitted with the positional switch, connected through manifolds with the compressed air source and with pneumohydraulic springs. The manifolds to springs are designed with reduction valves with different levels of control pressure conversion. Air cavities of springs are connected to atmosphere by manifold with a throttle and pressure recorder. Backpressure cavities of the springs are connected by manifolds to hydraulic cavities of high pressure of pneumohydraulic converters of pressure. The air cavities of converters are connected to the compressed air source by a manifold with shutoff valve connected with atmosphere.

EFFECT: increase of clearance and improvement of smoothness of motion.
