| 20120072086 | Apparatus and Method For Increasing Transmission Line Fluid Pressure - A transmission system that includes a transmission, a pressure sensor, a pressure booster, and a controller. The pressure booster being capable of raising the pressure of transmission fluid inside a closed-loop transmission by lowering the sensed pressure coming from the pressures sensor and being sent to the controller, thereby initiating a response from the controller that results in higher fluid pressures. The pressure booster does not lower the sensed pressure when the vehicle, and therefore, the transmission, is not in operation. Additionally, the pressure booster also does not increase the electric current through the electrical components of the fluid control system. The result is a transmission with a “firmer” feel between shifts and the correction of weak shifting problems such as gear slip. | 03-22-2012 |
| 20120064981 | Apparatus and Method For Limiting Torque Transmitted by Elongate Driving and Driven Members - An apparatus and method for limiting torque transferred from an engine or motor to a drive shaft or other components. In some embodiments, the torque-limiting device has a spindle disposed within both coupling flanges to increase the resistance to radial forces and to maintain coaxial alignment of the flanges and attached drive shafts. In some embodiments, the axial spacing of bearings that enable rotation of the coupling flanges is based upon the diameter of the spindle. In another embodiment, torque-limiting devices that maintain coaxial alignment may be used to modify vehicle drive shafts to enable long distance towing for long durations at high speeds. | 03-15-2012 |
| 20110251015 | Axial Thrust Load Redistribution System and Method for an Automotive Transmission - A system and method for altering the axial thrust load path within an automobile transmission eliminates the component end play in the transmission's roller clutch inner race and induces component end play in the transmission's rear sun gear. The resulting configuration moves portions of the axial thrust load path to across the roller clutch inner race and away from at least the transmission's sun gear and the reaction shell splines of the reaction shell. The system may include a kit in which an axially shortened roller clutch inner race and an appropriately sized bearing are provided. Additional kit components may include an axially shortened reaction shell. Alternatively, the roller clutch inner race and/or reaction shell may be shortened manually. A method of altering a preexisting transmission to have a new axial thrust load path is also provided. | 10-13-2011 |
| 20110078885 | Low Clearance Machined Part Mating System - A device, system, and method for generating low clearance slidably mated parts. In an exemplary embodiment, the system includes a measurement device having a non-contact micrometer capable of coincidentally indicating opposing edge data, rotational and linear air bearing slides, and a holding device. The non-contact micrometer allows for measurement of a plurality of parameters of a first part including the diameter and the difference between an edge of the first part and a reference point. The coincidental measurements are used to determine the size and geometric errors associated with the first part after suitable error elimination. In an exemplary system, a processing machine may be instructed by the measurement device to remove material from a second part so that the first part and the second part when mated together have a very low clearance tolerance level, e.g., as little as 0.00005 inches or less. | 04-07-2011 |
| 20100224803 | Valve Body Fluid Rerouting System - There is provided a fluid rerouting system for valve bodies that use hydraulic pressure, via a balance pressure line, to move spools. In an exemplary embodiment, the system comprises a valve sleeve having a plurality of ports that are substantially aligned with a plurality of fluid connections in the mating bore, except that no valve sleeve port aligns with the balance pressure line. The system also includes a spool having a plurality of lands that are sized and configured to fit slidably in said valve sleeve. The combination of the valve sleeve and at least one of the lands form a chamber, fluid access to which is via an aperture traversing the land. Means for blocking the access of said balance pressure line to said valve sleeve are also included. | 09-09-2010 |
