摘要： A variable pitch screw-driven system includes a rotatable drive screw powered by a motor actuator. A cam sleeve includes a nut section and is disposed about the drive screw and is linearly translatable in response to rotation of the drive screw. The cam sleeve includes a cam track with a fixed cam follower positioned to travel within a cam track. Linear translation of the cam sleeve is altered by tracking of the cam follower within the cam track such that rotation of the cam sleeve is effected simultaneously with rotation of the drive screw resulting in an effective variable pitch of the variable pitch screw-driven system wherein linear translation of the cam sleeve results from both rotation of the drive screw and rotation of the cam sleeve.

摘要： A park brake apparatus for a vehicle electric brake comprises an electric motor having a rotational output shaft coupled to a brake mechanism. Rotational movement of the electric motor in a first direction causes application of brake force in the brake mechanism and rotational movement of the electric motor in a second direction opposite the first direction causes release of brake force in the brake mechanism. An armature for the electric motor includes a plurality of radially extending armature arms. A solenoid has a plunger movable between extended and retracted positions. In the retracted position, the plunger is free of the radially extending armature arms and the armature spins free of the plunger. In the extended position, the plunger engages the radially extending armature arms, locking the armature in place and maintaining a park brake state.
