HIGH-TORQUE FRICTION CLUTCH Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: friction clutch includes drive and driven shafts connected through friction disks and plunger for transmission of pressure force to friction disks. Clutch is provided with pressure spring for forming pressure force and hydraulic positive-displacement transmission for reducing pressure force created by pressure spring and transmitting this force to friction disks. Hydraulic positive-displacement transmission includes plungers of different areas connected through cavity filled with working fluid. EFFECT: control of torque; reduced overall dimensions; ease in use and facilitated manufacture of clutch. 2 cl, 2 dwg
