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 201 having a first diameter portion 202 and a second diameter portion 203, the second diameter portion having a greater diameter than the first diameter portion. A park brake system may further comprise a spring 207 disposed at least partially around a circumference of the motor shaft, a wire coil 204 disposed at least partially around a circumference of a bobbin, a one-way clutch 210 disposed at least partially within the bobbin and coaxial to the motor shaft, an annular magnet 211 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.
