Filed:

Sep 12, 2003

Appl. No.:

10/661996

Inventors:

David R. Llewellyn - West Bloomfield MI, US
William G. Spadafora - Clarkston MI, US
Jason G. Kramer - Sterling Heights MI, US

Assignee:

Dana Corporation - Ottawa Lake MI

International Classification:

B62D006/00

US Classification:

701 43, 180 78

Abstract:

A fail-safe torque transducer, and automotive power steering system, utilizing a two-stage series coupled torsion bar system. A first stage torsion bar provides tuning of the steering system, and by reducing its diameter relative to the second stage, provides a lower torsional spring rate and higher operational stress level than that of the second stage. The second stage torsion bar provides the stress/strain indicia referenced by a torque-measuring device, and is stressed at a lower level than the first stage and therefore has a higher cycle life than that of the first stage bar. Hence, if stress related failure ever occurs, it will only occur in the first stage torsion bar, thereby preventing any torque from reaching the second stage, thereby causing a zero strain signal and thus rendering the system fail-safe and not subject to instability of vehicle steering if the torsion bar breaks.

International Classification:

F02M 61/00

US Classification:

123456, 123468, 123467, 123470

Abstract:

A fuel injection system includes a fuel supply rail, a fuel injector configured to control the delivery of fuel from the fuel supply rail, and a noise filtering device engaging an upstream end of the fuel injector and/or positioned at least partially within the fuel injector. The noise filtering device defines a fuel passage configured to direct fuel from the fuel supply rail into the fuel injector. The noise filtering device can include one or more of several features including a pocket, a wrap-around shape to conform to the inlet end of the fuel injector, a face-sealing portion, a compression section, and a plurality of parallel restriction passages.

International Classification:

F02M 59/46
F02M 55/02

US Classification:

123456, 123467, 123468

Abstract:

A fuel injection system includes a fuel supply rail having a supply opening. A fuel injector is coupled to the fuel supply rail and configured to control the delivery of fuel from the fuel supply rail through the supply opening. A noise filtering device engages an upstream end of the fuel injector. The noise filtering device has a projecting portion extending at least partially into the supply opening along an axis, and the noise filtering device defines a restriction passage for directing fuel from the supply rail into the fuel injector. A face seal is established at a transverse face adjacent the supply opening.

US Classification:

701 43, 701 1, 701 48, 701 53, 701 71, 340507

Abstract:

Systems and methods for mitigating failure mode effects in a steer-by-wire system. The system includes a controller configured to alter a direction of the vehicle when the controller is in a failure mode. A steering device is coupled to a detector. The detector is configured to detect a steering input from a driver and output a signal representative of the steering input. A first actuator is coupled to a first control device. The first control device is configured to generate a first control signal representative of the steering input when the controller is in the failure mode. The first actuator alters the direction of the vehicle by removing energy from the vehicle. A second actuator is coupled to a second control device. The second control device is configured to generate a second control signal representative of the steering input when the controller is in the failure mode. The second actuator alters the direction of the vehicle by adding energy to the vehicle.

International Classification:

B05B015/04

US Classification:

239/120000

Abstract:

A spray application system includes an enclosed spraybooth area in which airborne particles are generated and a scrubber system is located below the enclosed spraybooth area. The scrubber system includes an inlet receiving water and air from the spraybooth area along with airborne particles. The scrubber system transfers the airborne particles to the water for cleaning the air. A generally downwardly opening noise reflector is located directly over the inlet of the scrubber system and is configured to reflect sound generated by the scrubber system back into the inlet of the scrubber system. The reflector is spaced from the inlet of the scrubber system a distance equal to approximately the width of the inlet.
