Abstract
A locking mechanism for a caliper assembly of an electromechanical brake for a wheel rotor includes a motor gear of a motor. A pawl is pivotable relative to the motor gear and extends from a first end to a second end. The first end includes a pair of arms and the second end includes a locking tab. The pawl has a first position in which the locking tab is spaced from the motor gear to permit torque transfer between the motor gear and the gear train and a second position in which the locking tab engages the motor gear to prevent torque transfer between the motor gear and the gear train. First and second permanent magnets are provided on the respective arms. An electromagnet cooperates with the first and second permanent magnets to place the pawl in the first position or the second position.
