Abstract:
1. A brake assembly, comprising: a motor including a drive shaft rotatable about an axis; a hub drivable via the drive shaft about the axis and attached to the drive shaft through a center aperture of the hub, a surface of the hub including a first plurality of teeth; a piston non-rotatably secured to a housing of the motor and having a second plurality of teeth that, in a braking mode, engage the first plurality of teeth, where the piston is adapted to move axially along the axis; a spring for biasing the piston axially away from the surface of the hub for causing disengagement of the second plurality of teeth with the first plurality of teeth; and an actuator adapted to rotate about the axis for moving the piston axially along the axis toward the surface of the hub to engage the second plurality of teeth with the first plurality of teeth.
