6354089, Mar 12, 2002
Filed:
Mar 8, 2000
Appl. No.:
09/520464
Inventors:
Richard J. Lech - Burlington IA
Larry A. Johnson - Burlington IA
Assignee:
Case Corporation - Racine WI
International Classification:
F17C 300
US Classification:
62 502
Abstract:
A work vehicle is disclosed, the vehicle including first and second hydraulic circuits provided with first and second fluids, wherein the fluids are to be is kept apart; at least one fluid cooler for cooling at least one of the fluids; and a means for transferring heat from the hotter fluid to the cooler fluid. Also disclosed is a fluid cooling apparatus for a work vehicle, the work vehicle including a transmission with a first fluid and a hydraulic circuit with a second fluid. The cooling apparatus includes at least one fluid cooler for cooling at least one of the fluids, and an apparatus for transferring heat from the hotter fluid to the other fluid. Also disclosed is a method of cooling fluids of a work vehicle provided with a first hydraulic circuit including a first fluid and a second hydraulic circuit including a second fluid, the fluids to be kept separate. At least one of the hydraulic circuits includes a fluid cooler and a pump. The vehicle is further provided with a heat transfer apparatus for transferring heat from the hotter fluid to the other fluid.

Ride Control Apparatus And Method

View page
US Patent:
6398227, Jun 4, 2002
Filed:
Oct 13, 2000
Appl. No.:
09/687327
Inventors:
Richard J. Lech - Burlington IA
Alan D. Berger - Winfield IL
Danley C. K. Chan - Chicago IL
Dennis J. Heyne - Burlington IA
Assignee:
Case Corp. - Racine WI
International Classification:
B60G 1700
US Classification:
280 5515, 280 55, 280 5514, 280 6159
Abstract:
An apparatus for adjusting the ride of a load carrying vehicle is disclosed. The apparatus includes a sensor, a controller, and an adjustable accumulator assembly. The sensor measures a load on a load holding hydraulic circuit. The controller is operatively connected to the adjustable accumulator assembly. The controller is capable of adjusting the precharge pressure in the accumulator in response to the load measured by the sensor.

Hydraulic System And Method For Regulating Pressure Equalization To Suppress Oscillation In Heavy Equipment

View page
US Patent:
6474064, Nov 5, 2002
Filed:
Sep 14, 2000
Appl. No.:
09/661348
Inventors:
Dennis J. Heyne - Burlington IA
Richard J. Lech - Burlington IA
Eric Sharkness - Burlington IA
Assignee:
Case Corporation - Racine WI
International Classification:
F16D 3102
US Classification:
60468, 60469, 91 38
Abstract:
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.

System For Reducing Boom Swing Oscillation In A Backhoe Assembly

View page
US Patent:
6532738, Mar 18, 2003
Filed:
Sep 25, 2001
Appl. No.:
09/962893
Inventors:
Eric Sharkness - Troy MI
Dennis Heyne - Burlington IA
Richard J. Lech - Burlington IA
Assignee:
Case Corporation - Racine WI
International Classification:
F16B 3102
US Classification:
60468
Abstract:
A system for damping incipient oscillation in a linkage such as a backhoe assembly includes a crossover valve that connects the two supply lines that provide hydraulic fluid to a linkage actuator such as a boom swing hydraulic cylinder. The crossover valve is configured to open in response to the deceleration of the backhoe assembly.

Method For Retrofitting A Swing Damping Valve Circuit To A Work Vehicle

View page
US Patent:
6640409, Nov 4, 2003
Filed:
Sep 25, 2001
Appl. No.:
09/962818
Inventors:
Eric Sharkness - Troy MI
Dennis Heyne - Burlington IA
Richard J. Lech - Burlington IA
Assignee:
Case Corporation - Racine WI
International Classification:
B23P 2300
US Classification:
294011, 91420
Abstract:
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.

Hydraulic System For Suppressing Oscillation In Heavy Equipment

US Patent:
6647721, Nov 18, 2003
Filed:
Nov 7, 2001
Appl. No.:
10/039399

Hydraulic Swing Damping System

View page
US Patent:
6886278, May 3, 2005
Filed:
May 22, 2003
Appl. No.:
10/443309
Inventors:
Eric Sharkness - Troy MI, US
Dennis Heyne - Burlington IA, US
Richard J. Lech - Burlington IA, US
Assignee:
CNH America LLC - New Holland PA
International Classification:
E02F005/02
F15B011/08
US Classification:
37348, 60468, 91420
Abstract:
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.
