US Patent:

57343101, Mar 31, 1998

Filed:

Feb 15, 1996

Appl. No.:

8/601798

Inventors:

Darrell E. Ankney - Dixon IL
Joel F. Klein - Sterling IL
Curtis W. Fisher - Sterling IL

Assignee:

Borg-Warner Automotive, Inc. - Sterling Heights MI

International Classification:

H01F 708

US Classification:

335228

Abstract:

A magnetic latching solenoid assembly comprises a bobbin having a central aperture formed therethrough along a central axis and having a solenoid coil wrapped therearound, and a metal polepiece secured at least partially within the bobbin. An at least partially metal armature is slidably movable within the central aperture. The polepiece includes a depression formed therein with a first flat formed at the bottom of the depression. The depression has a first wall formed at a first angle with respect to the central axis. The armature has a protruding portion for cooperation with the depression, the protruding portion having a second flat formed thereon for metal-to-metal engagement with the first flat, and having a second wall formed at a second angle greater than the first angle so that the first and second walls do not contact each other when the first and second flats are in contact.

Darrell E. Ankney - Dixon IL, US

International Classification:

G01F 23/24
F16N 29/02
B64D 45/00

Abstract:

Disclosed is an actuator level detection system of an aircraft. The system includes an actuator containing fluid that defines a resistivity and including a first contact point and a second contact point. The system includes a first contactor disposed about the actuator cooperating with the first contact point to define a first contact resistance that includes the resistivity. The system includes sensor circuitry includes a conductive path defining a conductive path resistance, between the first contact point and the second contact point. The sensor circuitry has a total resistance that includes the first contact resistance and the conductive path resistance.

- Charlotte NC, US
Darrell E. Ankney - Dixon IL, US

International Classification:

F16D 65/18
F16D 55/38
B64C 9/16

Abstract:

A proportional brake is provided and includes first and second bodies, a spring element, a coil and a booster coil. The first body includes brake plates and the second body includes thrust plates. The second body is disposed such that the thrust plates are interleaved with the brake plates and is rotatable and movable with respect to the first body. The spring element urges the second body to move toward the first body such that the thrust plates are urged toward braking engagements with the brake plates. The coil is provided at a first side of the brake plates and, when energized, generates a first flux moment on the second body in opposition to the spring element. The booster coil is provided at a second side of the brake plates and, when energized, generates a second flux moment on the second body in support of the spring element.

B64D 45/00

Abstract:

A method for braking a motor in a high lift system of an aircraft, the high lift system comprising a central power drive unit for moving high lift surfaces arranged at a wing through providing rotational power by means of a transmission shaft to a plurality of drive stations operably coupled with the high lift surfaces; which power drive unit is operatively coupled to a controller and comprises at least one electric motor coupled therewith. The method includes determining a braking requirement for the at least one electric motor, measuring at least one of a current command to the motor and a current speed and direction of the at least one electric motor, based on the braking requirement, applying a braking command to the at least one electric motor, and reducing the braking command as the at least one electric motor comes to rest.
