Patent number: 6530426Abstract: A motor drive-control device drive-controls a plurality of auxiliary devices with a single motor while securing a necessary capacity of the auxiliary devices side in correspondence with usage conditions. As such, in an air-conditioning system, necessary speeds of auxiliary devices such as a compressor and a warm water pump are calculated based on a necessary cooling capacity and a necessary heating capacity. The higher of these two necessary speeds is set as the motor speed for driving the auxiliary devices. The motor is thus controlled to this speed. Therefore, even if the air-conditioning heat load varies greatly due to changes in the usage environment, cooling and heating capacities necessary for air-conditioning temperature control can be obtained at all times.Type: GrantFiled: April 12, 2000Date of Patent: March 11, 2003Assignee: DENSO CorporationInventors: Hiroshi Kishita, Yasuhiko Niimi, Yasushi Yamanaka

Patent number: 6241038Abstract: A remote drop box can be provided for tractor hydraulic drives; however, a system for providing lubrication to and cooling of the remote drop box is necessary. Maximum drawbar pull and maximum road speed capability are both desirable when a variable hydrostatic motor defines the working range. The hydrostatic motor must be operated very close to its maximum rated operating speed during roading, which leaves very little margin for overspeeding that occurs when the tractor is roading downhill. An improved overspeed control is also desirable. A problem encountered when a hydrostatic drive is used with a high torque engine in that, as the engine speed drops, the available charge pump flow also drops and eventually reaches a point where the required servo pressure to maintain the hydraulic pump in stroke cannot be maintained. Such a condition needs to be alleviated to provide an effectively operating hydrostatic drive system.Type: GrantFiled: November 2, 1999Date of Patent: June 5, 2001Assignee: New Holland North America, Inc.Inventors: David A. Young, Vladimir M. Kowalyk
