Patent number: 7856951Abstract: An invention relating to a control apparatus and a control method for a hydraulically driven cooling fan for reducing the peak pressure produced upon reversing the switch position of a switching valve, without stopping an engine, and without greatly modifying existing hydraulic circuitry or increasing the apparatus cost. In the invention, in the case that a reversing switch has been operated so as to output a reversal processing commencement instruction signal, control is carried out such that, under the condition that the rotational speed of the engine has decreased to not more than a stipulated rotational speed, capacity adjusting means is controlled, so as to reduce the capacity of a hydraulic pump, and thus reduce the fan rotational speed, and then the switch position of the switching valve is reversed.Type: GrantFiled: July 6, 2006Date of Patent: December 28, 2010Assignee: Komatsu, Ltd.Inventors: Mitsuhiko Kamado, Shigeru Yamamoto, Tomohiro Nakagawa

Patent number: 7841307Abstract: In a cooling fan drive system for a travel type working machine, the rotational speed of a cooling fan is controlled to the optimum rotational speed in accordance with temperature increase of the temperature of an engine cooling water, and the engine rotational speed is smoothly increased when the engine rotational speed is increased under travel acceleration. A fourth fan target rotational speed calculator 35e and a minimum value selector 35f are provided, and under non-operation, the fan target rotational speed is set to a low rotational speed irrespective of the temperature. When an acceleration pedal 12 is depressed to increase the rotational speed of the engine under travel acceleration, the increase of the drive pressure of a hydraulic motor 23 due to increase of the rotation of the cooling fan 9 is suppressed, and the load on the engine 1 is reduced.Type: GrantFiled: October 24, 2006Date of Patent: November 30, 2010Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Kentarou Itoga, Tsuyoshi Nakamura, Kazunori Nakamura

Patent number: 7814963Abstract: A cooling system for a work vehicle is disclosed that includes first and second heat exchangers disposed one above the other to create two discrete flow paths. The upper heat exchanger is an engine water cooler and the lower heat exchanger may be an intercooler, an oil cooler or a refrigerant condenser. The lower heat exchanger is disposed forward of the upper heat exchanger. Additional heat exchangers may be positioned in front of the first and second heat exchangers to provide additional cooling. The first and second heat exchanger may be cross-flow heat exchangers conducting the fluid to be cooled laterally through the core of the heat exchanger.Type: GrantFiled: December 7, 2007Date of Patent: October 19, 2010Assignee: CNH America LLCInventors: William H. Adamson, Stephen M. Balcom, Daniel A. Morey, Daniel M. Ruedinger

Patent number: 7778028Abstract: Electrical units are effectively cooled, even if the longitudinal length of the cover member in which the electrical units to be cooled are accommodated is short, by easily guiding a flow of air during operation toward the electrical units. A second cover member which constitutes at least a part of a body cover together with a first cover member is positioned ahead of the first cover member which accommodates an electrical unit to be cooled. Inlets which let a flow of air during operation into the second cover member are disposed in the second cover member. An outlet for discharging a flow of air during operation out of the first cover member is provided in the first cover member.Type: GrantFiled: September 8, 2009Date of Patent: August 17, 2010Assignee: Honda Motor Co., Ltd.Inventors: Gen Tanabe, Ryohei Kitamura, Yasuyuki Kadowaki, Takashi Arai
