  • Patent number: 7252615
    Abstract: This invention details a lubrication system for an automatic transmission, specifically the bearings of the planetary pinion gears. The planetary carriers have grooves formed in spider and flange sections thereof to carry the lubricating material from the inner diameter of the planetary carrier to the inner diameter of each pinion gear bearing mounted in the planetary carrier. The invention further includes two thrust washers that are assembled on opposing sides of each pinion gear that have axially and radially extending slots that further carry the oil between the inner diameter of the planetary carrier and the outer diameter of the planetary carrier. Lastly, the invention discloses a method for lubricating the pinion gears of the planetary carrier.

  • Publication number: 20040107922
    Abstract: A dual temperature control system as part of an engine cooling system. In one aspect, a valve is regulated as a function of engine load and disposed in a by-pass line between the radiator and the coolant pump. The valve is designed to normally block the by-pass line, but permits coolant to by-pass the thermostat and be conveyed from the radiator to the engine when the load of the engine approaches a wide-open-throttle condition. In another aspect, both high-temperature and low-temperature thermostats are employed and a normally closed valve is actuated when the load of the engine approaches a wide-open-throttle condition to permit coolant to be conveyed through the low-temperature thermostat and on to the engine.

  • Publication number: 20040103673
    Abstract: A method for detecting a low-charge state in an air conditioning system. In one aspect, the temperature/pressure of the discharge of the condenser is measured to determine whether a low-charge state exists in the refrigeration system by calculating the degrees of subcooling of the refrigerant and comparing that to a predetermined minimum value. In another aspect, the temperature/pressure of the discharge of the compressor is measured to determine whether a low-charge state is indicated by calculating the degrees of superheat of the refrigerant and comparing that value with a predetermined maximum value. An air conditioning checker is also disclosed.

  • Patent number: 6397112
    Abstract: A method is provided for updating an array of data point cells in a surface or table representation of memory. The three-dimensional surface array is modeled as a square bordered by four cells with one cell at each corner. Between each array corner cell, the array spacing is typically divided into three zones. As such, nine sub-regions of the array square are defined. Depending upon which of the nine sub-regions the calculated error point falls into when accessing the array, different cells are updated. In the case of a two-dimensional table array, typically three sub-regions are defined between adjacent cells. Depending upon which sub-region the calculated error point falls into, one or both of the table array cells is updated. As a further feature of the present invention, the amount of adaptive gain applied to each cell to be updated is adjusted depending upon which sub-region the calculated error point falls within.

  • Patent number: 6374700
    Abstract: A vehicle transmission housing or four-wheel drive transfer case housing which is shorter than previous arrangements, with the output shaft extending beyond the end thereof. As such, the drive shaft slip yoke or the output fixed yoke is mounted on the extended end of the shaft exterior of the seal at the exit end of the housing or transfer case, rather than extending through the seal into the housing or transfer case. The advantages include generally weight, part and machining reduction; reduced seal wear and performance requirements and, hence, minimized oil leakage; elimination of the usual grinding/polishing operations on the yoke; and consequent cost reduction.

  • Patent number: 6357226
    Abstract: A control system is described for optimizing the reduction of nitrogen oxides in exhaust gas produced by an internal combustion engine, especially those internal combustion engines that employ a lean air-fuel ratio. The control system employs a temperature control assembly that is capable of selectively heating the exhaust gas prior to introduction into the NOx catalyst system, thus rapidly bringing the temperature of the NOx catalyst system up to operating temperature.

  • Patent number: 6345837
    Abstract: An air bag module which includes a panel member having an integral reaction canister having a plurality of reaction walls and a manifold assembly having a manifold. The manifold includes at least one deployment door retaining channel and is operable for retaining an air bag cushion, an inflator, and a deployment door. The deployment door includes at least one retaining bead and a trim portion which are separated by a pliant spacing leg. As the reaction canister is incorporated into the panel member, the need for a separate reaction canister component is eliminated, thereby reducing cost, weight and overall size of the air bag module and allowing the manifold assembly to be used across a wider range of vehicles. The retaining bead and spacing leg flexibly couple the cover door to the manifold and allow the cover door to be repositioned during installation of the manifold assembly into the panel member so as to eliminate gaps, puckering and other defects in the appearance or the vehicle interior.

  • Patent number: 6314422
    Abstract: A method is provided for accessing files on a client node which is connected to a server node across a network channel. A first file is displayed on the client node, and context information indicative of this first document is stored. Rather than using a “hard” link which specifies a specific path/filename, a dynamic softlinking process is used to access a second file. A link, similar to a hyperlink, can be selected on the first displayed file to access a second file, where the link includes information indicative of the second file. To determine a file identifier for the second document, a data structure, having a plurality of file identifiers, is accessed using the context information and link information. The second file can then be retrieved from the server node via the network channel using the file identifer and displayed on the client node.

  • Patent number: 6295713
    Abstract: A method for attaching a soft top to a motor vehicle body tensions the soft top without a separate tensioning device. The method includes the general steps of attaching a support member to the motor vehicle for pivotal movement about a transverse pivot axis, supporting an upper rear corner of the top with the support member, and tensioning the top by upwardly and rearwardly biasing the upper rear corner of the top with the support member. The support member functions to provide a spring load for tensioning the top. In the preferred method, the support member is elastically deformed for tensioning the top.

  • Patent number: 6291807
    Abstract: A method and apparatus for in-situ induction tempering is provided in which an induction coil is used to temper a part in-situ at the location. The use of an induction coil in-situ at the heat treating location eliminates the need (and time and expense) of a multi-step process wherein in part to be tempered would otherwise have to be moved from the quenching location to the tempering location, such as at a tempering furnace. It also eliminates the need for the tempering furnace, which is a great space savings. In one form of the invention, the power supplied to the induction coil is controlled by a closed-loop temperature controller that is controlled by the temperature in the vicinity of the tempered part, as opposed to simply be controlling on time at temperature.
