Voice coil linear activated park brake

A park brake system comprising:

• a tapered motor shaft having a first diameter and a second diameter, the second diameter being greater than the first diameter;
• a spring disposed at least partially around a circumference of the tapered motor shaft;
• a voice coil disposed at least partially around a circumference of a bobbin comprising a ferromagnetic insert;
• a first one-way clutch housed at least partially within the bobbin, the first one-way clutch disposed coaxial to the tapered motor shaft;
• and
• an annular magnet disposed coaxial to the tapered motor shaft and proximal to the first one-way clutch;
• wherein, in response to a first voltage applied to the voice coil, the first one-way clutch translates axially in a first direction with respect to the tapered motor shaft and engages with the second diameter, and
• wherein, in response to a second voltage applied to the voice coil, the first one-way clutch translates axially in a second direction and is disposed about the first diameter.
