  • Actuator for an electric parking brake system
    Patent number: 9835213
    Abstract: An actuator for an electric parking brake system includes an outer housing, a motor, a planetary gear mechanism and a belt-wheel mechanism that are received in the outer housing, and an isolation member. The belt-wheel mechanism includes a driving wheel, a follower wheel, and a transmission belt. The driving wheel is connected with the motor. The follower wheel is connected with the planetary gear mechanism. The isolation member has a first spacer fixed to the driving wheel via the motor, a second spacer fixed to the follower wheel, and a buffering element disposed between the second spacer and the outer housing. The second spacer is disposed above and assembled to the first spacer. The isolation member defines the center-to-center distance between the driving wheel and the follower wheel, and absorbs vibrations from the motor and the planetary gear mechanism.
