Publication number: 20060237958Abstract: A system for automatically moving a stabilizer of a work vehicle is disclosed. A joystick is connected to an electronic controller, which in turn, is connected to valve drivers to drive stabilizer raising and lowering valves. In one mode of operation, the controller is programmed to move the stabilizers up or down at a rate that is proportional to the deflection of the joystick from a neutral position. If the operator holds the joystick in a certain position or range of positions, the controller enters a second mode in which it automatically raises the stabilizers even if the joystick is released. The stabilizer can be placed in a third mode of operation by moving the joystick rapidly back and forth. When the operator does this, the controller is configured to reduce the ramp rate or damping of its response to joystick movement.Type: ApplicationFiled: June 21, 2006Publication date: October 26, 2006Inventors: Peter Dix, Dennis Heyne

Patent number: 7032332Abstract: An electronic control for damping oscillation of a swinging backhoe assembly includes a crossover valve that connects the hydraulic lines that supply hydraulic fluid to the boom swing cylinders to each other whenever an electronic controller senses incipient oscillation or swinging of the backhoe assembly. The electronic controller senses such parameters as pressure in the conduits and the position of the operator controls or the position of the boom swing control valve that the operator controls to determine incipient oscillation when the backhoe assembly is stopped. The crossover valve may remain open for a predetermined period of time.Type: GrantFiled: May 22, 2003Date of Patent: April 25, 2006Assignee: CNH America LLCInventors: Eric Sharkness, Dennis Heyne, Richard J.

Patent number: 6647721Abstract: The invention provides a system for regulating pressure equalization in hydraulic mechanisms to suppress oscillation in heavy equipment. The system includes a first and second hydraulic lines, a crossover valve in communication with each of the first and second hydraulic lines, a timing system in communication with the crossover valve, and a motion detector in communication with a heavy equipment component. The motion detector senses a linkage motion and operatively opens the crossover valve, which remains open as directed by the timing system.Type: GrantFiled: November 7, 2001Date of Patent: November 18, 2003Assignee: Case, LLCInventors: Dennis Heyne, Richard J. Lech, Eric Sharkness, David W. Swaim, Guy T. Stoever, Ian MacLeod

Patent number: 6640409Abstract: A method for retrofitting a swing damping circuit to a work vehicle such as a backhoe includes disconnecting a boom swing valve from a boom swing cylinder, and coupling the swing damping circuit to the boom swing valve. Alternatively, it may include replacing a boom swing valve with a combined boom swing valve and swing damping circuit that form a unitary valve body.Type: GrantFiled: September 25, 2001Date of Patent: November 4, 2003Assignee: Case CorporationInventors: Eric Sharkness, Dennis Heyne, Richard J.
