CLUTCH-REDUCTION GEAR WITH HYDRAULIC RESILIENT MEMBER Russian patent published in 2011 - IPC B60K17/10 F15B1/02 B60K23/00 F16D43/28 

FIELD: transport.

SUBSTANCE: invention relates to machine building and can be used in drive lines of tractors and in road-building machines which work in transient modes of motion. Planetary clutch contains planetary gear group connected with engine, hydropneumatic accumulator, hydraulic pump mechanically connected with sun gear of the gear group, and hydraulic control valve. The clutch is equipped with additional hydraulic pump which is kinematically connected with crown gear. Both pumps are connected with hydropneumatic accumulator via hydraulic control valve, and carrier of the gear group is connected with engine.

EFFECT: enhancement of clutch kinematic capabilities, higher reliability and durability of powertrain parts operation, and improvement of vehicle characteristics by means of smooth variation of torsion torque transferred from engine to propellers.
