20100300797 | HYBRID TRANSMISSION HIGH VOLTAGE CONNECTOR AND TERMINAL BLOCK COOLING SYSTEM AND METHOD - A cooling system for an electrically variable transmission includes an electric motor having a plurality of connectors. The plurality of connectors are each assembled within a plurality of connector openings in a terminal block. Fluid from within a passageway is supplied by a pressurized fluid source, and an orifice for the passageway is located adjacent to one of the plurality of connector opening. The fluid flowing from the passageway is directed onto one of the plurality of connectors. | 12-02-2010 |
20110042159 | POWERTRAIN COOLING CIRCUIT - A vehicle, such as a loader, is disclosed. The vehicle includes a cooling system having a pump that communicates coolant to heat-generating components to be cooled by the coolant. | 02-24-2011 |
20110284309 | Transmission Fluid Warming and Cooling System - A system for heating and cooling the transmission fluid including a heat exchanger adapted to transfer heat between an engine coolant and a transmission fluid and a controller for controlling a valve to place the system into a select one of three modes including a heater core priority mode wherein no engine coolant flows to the heat exchanger, a heating mode wherein hot engine coolant flows directly to the heat exchanger from the engine and a cooling mode wherein cool engine coolant flows directly to the heat exchanger from the radiator, whereby the transmission fluid is heated in an efficient manner with minimal impact on passenger compartment heating. | 11-24-2011 |
20130087403 | Utility Vehicle - A utility vehicle is provided. The utility vehicle may include a transmission including a transmission mechanism and a transmission case assembly for accommodating the transmission mechanism; and an air discharge duct coupled to the transmission case assembly, to discharge air from inside the transmission case assembly; wherein the air discharge duct includes an upward extending portion extending substantially upward from the transmission case assembly, and a downward extending portion which is bent back at an upper end portion of the upward extending portion, and then extends substantially downward; and the upward extending portion and the downward extending portion partially overlap with each other in at least either a forward and rearward direction or a rightward and leftward direction. | 04-11-2013 |
20140291060 | Machine Bearing System Including Hard Thin Film And Method Of Using Same - A bearing system includes a sleeve bearing supported on a shaft and a gear supported on the sleeve bearing. The shaft has an outer diameter shaft surface, the sleeve bearing has an inner diameter bearing surface and an outer diameter bearing surface, and the gear has a gear bore surface. At least one of the outer diameter shaft surface, the inner diameter bearing surface, the outer diameter bearing surface, and the gear bore surface includes an isotropic surface finish and a hard thin film over the isotropic surface finish. During a break-in period of operation of the bearing system, the hard thin film over the isotropic surface finish breaks in a counter surface of the bearing system to extend a hydrodynamic lubrication period of operation of the bearing system. | 10-02-2014 |
