Filed:

Jan 20, 2017

Appl. No.:

16/070362

Inventors:

- Dublin 4, IE
Tyler Q. Curtis - Rockford MI, US

International Classification:

F16H 25/20
F16H 25/22
B64C 13/28

Abstract:

A ball screw assembly for use in an actuator is provided. The ball to screw assembly may include a ball screw supported for rotation by the actuator. A ball nut may be provided around the ball screw and may be held against rotation with the ball screw by said actuator. A primary load path may be provided between the ball screw and the ball nut for operatively coupling the ball nut with the ball screw. A secondary load path may be provided between the ball screw and the ball nut, wherein the secondary load path can be disengaged during a normal operating mode of the ball screw assembly and the secondary load path can be engaged during a second operating mode of the ball screw assembly.

- Dublin 4, IE
Sorin Gavriliuc - Caledonia MI, US
Christopher J. Jezewski - Coopersville MI, US
Tyler Q. Curtis - Rockford MI, US

International Classification:

F16H 25/24
F16H 25/22

Abstract:

A self-locking nut and screw assembly may include a screw and a first nut rotatable and linearly translatable with respect to each other. The assembly may also include a first motor configured to provide torque to one of the screw and the first nut. The assembly may further include a locking mechanism configured to lock the screw to prevent backdrive when the motor is not providing torque to the one of the screw and the first nut.

B64C 13/50

Abstract:

A device and system for monitoring a load or applied force includes a body having first and second ends, a plate, a force-providing member connected to the plate, a first biasing member, and a first sensor. In embodiments the first biasing member is disposed between a portion of the body at or about the first end and a portion of the plate, and is configured to substantially retain the plate in an initial position during normal operation of the device; the first sensor is configured to sense a displacement (e.g., displacement position) with respect to the plate; and the body includes a portion configured to connect to or apply a force to another component. A controller may selectively instruct and/or operate a component, such as a motor, in response to an output generated or provided by the sensor. If an excessive force is sensed, the device may mitigate resulting damage.
