20110056192 | TECHNIQUE FOR CONTROLLING PUMPS IN A HYDRAULIC SYSTEM - A hydraulic system includes a plurality of pumps that provide pressurized fluid to a plurality of hydraulic actuators some of which work more that others. That system is controlled by producing a usage value for each of the plurality of pumps which indicates an amount that the respective pump has worked. One of the pumps is assigned to each hydraulic actuator in response to the usage values. The pumps with lower usage values are assigned to hydraulic actuators which work more, so as to equalize the use of each pump. The assignment of pumps to hydraulic actuators changes with changes in the usage values for the plurality of pumps. When a given one of the plurality of hydraulic actuators is to operate, hydraulic fluid is routed from the assigned pump to that given one of the plurality of hydraulic actuators. | 03-10-2011 |
20110135502 | HYDRAULIC RESERVOIR FOR HYDRAULIC REGENERATIVE CIRCUIT - A hydraulic reservoir includes a container having an internal volume, an internal wall dividing the internal volume of the container into a first section and a second section for separately containing the hydraulic fluid, and two one-way valves. The first one-way valve allows the hydraulic fluid to be drawn out of the first section of the hydraulic reservoir and substantially prevents a flow of the hydraulic fluid back into the first section. The second one-way valve allows the hydraulic fluid to be returned to the second section of the hydraulic reservoir and substantially prevents a flow of the hydraulic fluid out of the second section. A cooling/filtering loop may connect the second section and the first section such that the used fluid in the second section may be processed and returned to the first section in a substantially unused condition. | 06-09-2011 |
20110233931 | ENERGY MANAGEMENT SYSTEM FOR HEAVY EQUIPMENT - Equipment having an energy management system includes an articulated arm, a work implement, an energy management system, and a hydraulic circuit. The articulated arm includes hydraulic actuators designed to maneuver the articulated arm, and the work implement is fastened to the articulated arm. The energy management system is adjustable between a first configuration and a second configuration, and includes a hydraulic rotating machine and an electric rotating machine coupled to the hydraulic rotating machine. When the energy management system is in the first configuration, the hydraulic rotating machine and the electric rotating machine function as an electric motor powering a hydraulic pump. When the energy management system is in the second configuration, the hydraulic rotating machine and the electric rotating machine function as a hydraulic motor powering an electric generator. The hydraulic circuit is designed to supply a hydraulic fluid to drive the hydraulic actuators when the energy management system is in the first configuration, and is further designed to recover the hydraulic fluid from the hydraulic actuators and to generate electrical power when the energy management system is in the second configuration. | 09-29-2011 |

20120089279 | ENERGY MANAGEMENT AND STORAGE SYSTEM - Heavy equipment is designed for operation in a substantially-repetitive work cycle that includes lifting, rotating, and lowering steps. The heavy equipment includes a generator, an electrical bus, an energy storage component, and working components. The generator provides a substantially constant electrical output to the electrical bus, which is communicated to the working components. As such, the working components of the heavy equipment are driven directly or indirectly by the electrical output of the generator. The controller selectively couples the energy storage component to the electrical bus, and the energy storage component is configured to store electricity provided by the generator, and to provide electricity to the working components by way of the electrical bus. The electrical output of the generator is less than the power used by the heavy equipment during a portion of the work cycle, and the controller couples the energy storage component to the electrical bus to supplement the electrical output of the generator during the portion of the work cycle in which the electrical output of the generator is less than the power used by the working components of the heavy equipment. | 04-12-2012 |
