GEAR FOR LONGITUDINAL POSITIONING OF TRANSPORT ROBOT Russian patent published in 1997 - IPC

FIELD: robotics, automatic transportation facilities. SUBSTANCE: proposed gear includes control unit, logic unit, speed master unit, module controlling drive connected to motors-wheels connected in series, unit of speed sensor of motors-wheels which output is linked to input of feedback of module controlling drive. Gear differs from other known devices by insertion of transmission unit kinematically coupled via controlled clutch to shaft of motors-wheels and via overrunning clutch to flywheel accumulator of mechanical energy. Logic unit is connected with one of its outputs to input of module controlling drive meant for commutation of power supply of motors-wheels and to controlling input of electromagnetic clutch. With switching of the latter transmission factor of transmission unit determining ratio of angular speed of shaft of flywheel accumulator to angular speed of shaft of motors-wheels changes from zero to infinity in specified dependence on angle of turn of driving shaft. It provides for smooth stoppage of transport robot with turn of shaft of motors-wheels through fixed angle under any magnitude of mass and starting speed of robot. EFFECT: enhanced functional reliability of gear. 2 dwg
