CASE HISTORY OF A DEVELOPMENT PROGRAM TO SAVE ENERGY BY USING CLUTCHES WITH HYDRAULIC PUMPS AND MOTORS

After hydraulic failsafe brakes proved successful in many applications, a program was undertaken to develop a companion convenience-packaged hydraulic clutch. The developed clutch, which has been used in numerous applications, has stimulated new equipment design ideas. These have resulted in energy and space savings; equipment cost, noise, and maintenance reductions; employee and equipment protection, and equipment versatility. Four basic clutch-component configurations solve a variety of mechanical problems: clutch mounted between gearbox and pump, permitting hydraulic activity as required, without interrupting mechanical drive; clutch mounted between motor and gearbox, providing auxiliary power control for secondary operations, e.g. front-wheel drive assists; clutch mounted between two motor and drive stations, allowing use of either or both motors for two-station drive (two smaller vs. one larger motor); and clutch mounted between a right angle drive and two gearboxes, permitting torque to be applied to either operation. Illustrative case histories are presented.
