Patent number: 10890165Abstract: A vehicle includes a pump having a swash plate tiltable about a swashplate tilt axis, wherein rotation of the swashplate changes the title angle and effects a change in volumetric displacement of the pump. A controller is operatively coupled to the swashplate to effect rotation of the swashplate, the controller including a processor and memory, and logic stored in the memory and executable by the processor, the logic configured to automatically control at least one vehicle characteristic independent of a user input command.Type: GrantFiled: November 30, 2016Date of Patent: January 12, 2021Assignee: Parker-Hannifin CorporationInventors: David Mark Heathcoat, Kirk Ayres Lola, Roger Paul Gray, II, Kerry Brock, Michael T.

Patent number: 9908756Abstract: A constant pulling force winch control system includes a sensor that senses a degree of winding of a winch cable around a winch drum, and a control system configured to control a winch motor to achieve a constant pulling force on the winch cable based on the degree of winding sensed by the sensor. The sensor may be a position sensor that measures a position of the winch cable relative to a centerline of the winch drum as the degree of winding. The position sensor may sense an angular position of a tension plate relative to a tensioner shaft to measure the degree of winding. The winch motor may be a hydraulic winch motor or an electric motor, and the control system is configured to control the power applied to the hydraulic winch motor to achieve the constant pulling force based on the degree of winding sensed by the sensor.Type: GrantFiled: September 27, 2013Date of Patent: March 6, 2018Assignees: Parker-Hannifin Corporation, Warn Industries, Inc.Inventors: Oliver Heravi, Randy C. Karambelas, Roger Paul Gray, II, Alexander Milanese, Ronald P. Middendorf, Anthony J. Wroblewski, Kirk A. Lola, Mark D. Schuster, Thomas J. Larson

Publication number: 20160069404Abstract: A braking mechanism is provided for a hydraulic motor driven wheel utilizing a two-piece design of a hub that rotates by means of a drive shaft. A hydraulic chamber is created on the hub in which a piston resides. The piston is grounded (i.e., non-rotatable relative to the motor housing) in the sealed chamber. The piston face inside of the chamber has a radial set of face teeth. These face teeth are similar to the face teeth inside of the hydraulic chamber. When the chamber is pressurized, the piston face teeth are pushed away from the hub face teeth allowing the hub to freely rotate. When pressure is released from the chamber, a spring, or a number of springs, push the piston into the hub causing it to stop rotating relative to the piston.Type: ApplicationFiled: September 22, 2015Publication date: March 10, 2016Inventors: Craig FEUSSE, Roger Paul GRAY, II

Publication number: 20150292499Abstract: A hydrostatic transmission system includes a pump including a rotatable swash plate, wherein rotation of the swashplate effects a change in volumetric displacement of the pump. An actuator is coupled to the swashplate, the actuator operative to effect rotation of the swashplate to change the volumetric displacement of the pump. An electronic controller is operatively coupled to the actuator, the electronic controller configured to command the actuator to effect rotation of the swashplate.Type: ApplicationFiled: April 14, 2015Publication date: October 15, 2015Inventors: David Mark HEATHCOAT, JR., Roger Paul GRAY, II, Kirk Ayres LOLA, Kerry BROCK, Michael T.

Patent number: 8616528Abstract: Hydraulic powered assemblies 10 and 110 are disclosed. The assembly 10 includes a support unit 12, a hydraulic motor 14, and a driven member 16 that is integral with the hydraulic motor 14. The hydraulic motor 14 includes a power group 32 that includes six gerotor power units 34a-34f. Each gerotor power unit 34a-34f includes an inner rotor 40 that is fixed to a stationary through-shaft 24 and an outer rotor 42 that is mounted for hypocycloidal movement relative to the inner rotor 40. The driven member 16 includes segments 51 that support the outer rotors 40 within the segments 51. The segments 51 carry a winch cable receiving member 60 when the assembly 10 is used as a winch. The hydraulic powered assembly 110 is an alternative embodiment that includes two power groups 131 and 132. The power groups 131 and 133 may be symmetrical or asymmetrical.Type: GrantFiled: December 22, 2009Date of Patent: December 31, 2013Assignee: Parker Hannifin CorporationInventors: Roger Paul Gray, II, Mark Schuster, Richard Hynes, Jason Richardson, Jim McBurnett, Brook Cutshaw
