Abstract:

A mechanical linear actuator in an aircraft brake may include a ball nut, a ball screw, and an actuator drive unit housing. The ball screw may rotate to drive the ball nut axially. The ball screw and the actuator drive unit housing may form a series of annular raceways. The ball screw may have a first window corresponding to a first raceway and a second window corresponding to a second raceway. Balls may be inserted into the first raceway through the first window and into the second raceway through the second window.

International Classification:

F16H 25/24
F16H 25/22

Abstract:

The present disclosure provides an actuator assembly having a ball nut comprising a helical track and a ball screw. The ball screw of the actuator assembly includes a first translation bearing track having a first diameter, wherein the helical track and the first translation bearing track form a first translation bearing raceway in which a first translation bearing ball is disposed. The ball screw further includes a second translation bearing track having a second diameter, wherein the helical track and the second translation bearing track form a second translation bearing raceway in which a second translation bearing ball is disposed. The first diameter and the second diameter are not equal.

Abstract:

The present disclosure provides devices and methods related to park brake systems and methods. In various embodiments, a park brake system may comprise a motor shaft having a first diameter portion and a second diameter portion, the second diameter portion having a greater diameter than the first diameter portion. A park brake system may further comprise a spring disposed at least partially around a circumference of the motor shaft, a wire coil disposed at least partially around a circumference of a bobbin, a one-way clutch disposed at least partially within the bobbin and coaxial to the motor shaft, an annular magnet disposed coaxial to the motor shaft and distal to at least a portion of the bobbin, and a clutch release mechanism disposed coaxial to the motor shaft and around the first diameter portion. In response to a first voltage being applied to the wire coil, the one-way clutch may translate axially in a first direction relative to the motor shaft and engage with the second diameter portion; in response to a second voltage applied to the wire coil, the one-way clutch may translate axially in a second direction relative to the motor shaft and engage with the clutch release mechanism.
