FLUID-ACTUATED CLUTCH WITH ROTARY ABUTMENT PUMP Russian patent published in 1998 - IPC

FIELD: mechanical engineering; vehicle mechanical transmissions. SUBSTANCE: fluid-actuated clutch with rotary abutment pump has stator, rotor arranged inside stator and provided with spring-loaded vanes. Rotor is installed for rotation and forming high and low pressure zones of working fluid during the operation. Clutch has also spool with rod and piston installed for isolating above-indicated zones. Intermediate member is arranged with clearance between rotor and stator. Intermediate member has cylindrical inner surface and is installed for diametric displacement in stator guides. Clutch has at least two safety valves one of which is installed on intermediate member in high pressure zone, and the other, on stator for additionally placing the high and low pressure zones in communication with each other. Spool is located inside rotor and is provided with piston ring enclosing its rod and installed for displacement and fixing by means of dowels. Low pressure zone between stator and intermediate member is placed in communication with low pressure zone between intermediate member and rotor by means of channel. Clutch can be furnished with levers of the first kind secured on stator surface. Some ends of levers are hinge connected with tie-rod secured on intermediate member, and others are furnished with balance weights. EFFECT: enlarged operating capabilities. 3 dwg
