LUBRICATION SYSTEM OF PLANETARY GEAR OF HYBRID POWER UNIT OF VEHICLE (VERSIONS) Russian patent published in 2015 - IPC F01M1/02 F04C2/08 

FIELD: machine building.

SUBSTANCE: inventions can be used in vehicles, namely in lubrication systems of the hybrid power units (HPU). The lubrication system contains a crankcase (2), suction bell (3) with channel, channel (12), first and second pressure guns in the crankcase cavity (2). The movable part of the first pressure gun is created by pinion (15) and tooth-wheel (16) connected with the possibility to transfer the torque, with crown wheel (5). The tooth-wheel (16) of the movable part of the first pressure gun can be sleeve-like, with helical crown (17) engaged with the pinion (15). The fixed part of the first pressure gun can be made by the shaped casing (21) with collar (22). The movable part of the first pressure gun can be made by the eccentric (35) of the harmonic drive. The movable part of the second pressure gun is made by disk-like drive (23) and ring-like driven (24) rotors. Fixed part of the second pressure gun is made by through channel (25) and bore (26), and cover (27). The movable part of the second pressure gun is located in the cavity created by walls of the cylindrical bore (26) of the casing (21) of the fixed part of the first pressure gun. The movable part of the second pressure gun can have solenoid drive.

EFFECT: dense layout of the device.
