DOUBLE-FLOW FRICTION CLUTCH Russian patent published in 2009 - IPC F16D13/60 B60K17/02 

FIELD: machine building.

SUBSTANCE: invention is related to the field of machine building, in particular to double-flow friction clutches of disc type. Double-flow friction clutch comprises body, pressure plate and two slave discs, and also mechanism for connection of clutch, which is functionally combined by pressure mechanism with two disc springs and carriers that are rigidly connected to pressure plate. Clutch body is arranged in the form of shell, inside of which there are three lugs installed at the angle of 120° relative to each other. There are two cylinders with pistons arranged in every lug. In every cylinder there is trapezoidal groove for sealing ring, which also performs function of piston return. On external surface of body there is crown that is engaged with according internal crown arranged on flywheel body. Outside, on body of friction clutch there is sealing device arranged in the form of shell, on internal side of which there are four collars with three stop rings that form together with clutch body two cavities, to which working fluid is supplied through hoses. Inside body, opposite to pistons, there are master blocks installed, a pair for every piston. There are slave discs installed between master blocks.

EFFECT: increased efficiency of power plant due to reduction of losses in process of switching without interruption of power flow.
