  • Actuator and electromechanical disc brake having the same
    Patent number: 11098779
    Abstract: Disclosed is an electromechanical disc brake. The electromechanical disc brake includes a piston slidably disposed in a cylinder of a caliper housing to press a pad plate, an actuator including a motor and a speed reduction device for reducing a rotation speed of the motor, an output conversion device for converting a rotational motion from the speed reduction device into a linear motion and imparting a thrust to move the piston, an elastic member for moving the output conversion device to the original position when releasing braking, and a clutch device for releasing a torque acting on the speed reduction device such that the output conversion device is moved to the original position by the elastic member when releasing the braking.

  • Electric caliper brake with parking function
    Patent number: 9051982
    Abstract: Disclosed herein is a electric caliper brake with a parking function. The electric caliper brake includes a caliper submodule to apply pressure to a piston to press the disc by converting rotational motion into rectilinear motion through the received rotation power, an actuator submodule to produce braking force to perform the braking function and parking function, and a self-locking module to transfer the braking force by connecting the caliper submodule to the actuator submodule.
