Patent number: 9746005Abstract: A hydraulic drive system for an actuator uses a pair of pressure compensated hydraulic machines to control flow to and from the drive chambers of the actuator. The capacity of one of the machines is limited in a motoring mode to determine a maximum rate of efflux from one of the chambers. The pressure of fluid supplied to the other of said chambers is maintained at a predetermined level to provide motive force. The machines are mechanically coupled to permit energy recovery and charge an accumulator to store surplus energy.Type: GrantFiled: April 18, 2012Date of Patent: August 29, 2017Assignee: Concentric Rockford Inc.Inventors: George Kadlicko, John Gregorio, Tobin Gimber, Jeffrey Maney

Patent number: 9222486Abstract: A power distribution system includes a prime mover and a hydraulic drive system. The hydraulic drive system includes an accumulator to store energy and supplement that available from the prime mover. A control monitors torque imposed on the prime mover and utilizes energy stored in the accumulator to offload the prime mover when its operating conditions are to be changed. Effecting a change under reduced load conditions mitigates inefficient operation of the prime mover.Type: GrantFiled: April 18, 2012Date of Patent: December 29, 2015Assignee: Concentric Rockford Inc.Inventors: George Kadlicko, John Gregorio, Tobin Gimber, Jeffrey Maney

Patent number: 8596055Abstract: A hydraulic drive system for an actuator uses a pair of pressure compensated hydraulic machines to control flow to and from the drive chambers of the actuator by varying the controlled pressure of one of the machines. The machines are mechanically coupled to permit energy recovery and charge an accumulator to store supplies energy. The drive system may be combined with other services including a transmission for incorporation in a vehicle. The transmission uses a pressure compensated supply and torque control of the wheels.Type: GrantFiled: April 18, 2012Date of Patent: December 3, 2013Assignee: Concentric Rockford Inc.Inventor: George Kadlicko

Publication number: 20100300279Abstract: A hydraulic actuator system designed to inwardly contain major portions of its control system. The system includes a unique non-vented and air tight sealed reservoir with expandable bladder. This inward control system and non-vented reservoir optimize space saving advantages and eliminate the need for external elements typically used in a hydraulic system, while extending fluid life, reducing cavitation and fluid oxidation, and increasing performance in the hydraulic system. The system configurations can work for both a single or dual acting linear actuator and further can involve a motor, hydraulic pump, and electro-hydraulic valve circuit used to control fluid throughout the system.Type: ApplicationFiled: June 2, 2009Publication date: December 2, 2010Inventors: George Kadlicko, Wade Stone

Patent number: 7367257Abstract: An actuator has a position encoder provided by a helical groove formed in the piston rod. The groove is filled with a material of different magnetic characteristics to provide a smooth exterior surface and a varying discernible signal as the rod moves relative to the cylinder. An array of Hall effect sensors is provided around the rod to provide phase shifted signals as the rod moves so that the signal of one sensor may be correlated by the signals of other sensors.Type: GrantFiled: August 17, 2005Date of Patent: May 6, 2008Assignee: Haldex Hydraulics CorporationInventor: George Kadlicko
