SYSTEM FOR LUBRICATION AND CONTROL OF FRICTION CLUTCH Russian patent published in 2020 - IPC F16H57/04 F16H61/06 F16D48/02 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to friction clutch lubrication system. Lubrication and friction clutch control system includes oil pan, oil intake pipeline with which coarse filter is connected and gear pump. System also includes control unit, electrically driven shutoff-control valve, bypass valve, fine filter, oil cooler and pipelines. At that, gear pump consists of two sections. System is additionally equipped with a buffer device configured to set duration of smooth coupling clutch switching time by changing the volume of the buffer device and including two check valves. One of the valves connects the buffer device with the pipeline leading to the friction coupling, and the other one connects the buffer device to the oil pan. After each fine filter there are additional pipelines with bypass valves leading to oil pan. Friction clutch is configured to adjust the clamping force of the friction discs during the filling time of the buffer device.

EFFECT: enabling higher reliability.
