SYSTEM FOR SWITCHING OF FRICTION CLUTCHES WITH HYDRAULIC CONTROL OF SHIP'S SUMMING REVERSIBLE GEARBOX Russian patent published in 2021 - IPC F16D48/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, in particular to systems for switching on friction clutches. The system for switching on friction clutches with hydraulic control of the ship’s summing reversible gearbox contains a control pump, oil pipelines, and a control oil line. The pump discharge is made in the form of spool devices and a block of branch pipes of three-way distribution valves of the control device. The control device is made in the form of three spool devices in a single housing. The first, second and third output ports of the control device are connected by oil passages with the including cavities of the first, second and third friction clutches with hydraulic control. The fourth output port of the control device is connected by an oil passage to the oil sump of the gear reducer. The inlet pipes of the first, second, third and fourth three-way distribution valves are connected by oil pipes to the input port of the control device.

EFFECT: invention achieves increased reliability.
