Park brake apparatus for vehicle electric brake

A park brake apparatus for a vehicle electric brake comprising:

• an electric motor having a rotational output shaft;
• an armature on the electric motor rotational output shaft;
• a solenoid mounted proximate the motor;
• and
• a plunger for the solenoid, wherein the plunger has a first extended position and a second retracted position,
• wherein the rotational output shaft is coupled to a brake mechanism and causes application of brake force in the brake mechanism when rotated in a first direction and releases brake force in the brake mechanism when rotated in a second direction opposite the first direction,
• wherein the armature includes a plurality of radially extending armature arms, and
• wherein, in the first position, the plunger engages the radially extending armature arms, locking the armature and rotational output shaft in place and, in the second position, the plunger is free of the radially extending armature arms and the armature and rotational output shaft spin free of the plunger.
