WIPO Patent Application WO/2021/246828

A1

Disclosed are an electromechanical brake and an operating method therefor. The electromechanical brake according to the present embodiment may comprise: a piston that is provided to be able to move forward or backward so as to press a brake pad; a power conversion unit that receives driving force from an actuator, converts rotational motion into linear motion, and provides same to a piston; and a position adjusting unit that adjusts a relative position of the piston with respect to the power conversion unit, wherein the power conversion unit comprises: a spindle that receives driving force from the actuator and rotates; and a nut that is connected to the spindle and moves the piston forward or backward by moving forward or backward from the inside of the piston by means of rotation of the spindle in a first direction or a second direction, and the position adjusting unit comprises: a first screw thread formed on the outer circumferential surface of the nut; a second screw thread that is formed on the inner circumferential surface of the piston and meshes with the first screw thread; and an adjuster that is provided between the spindle and the nut and rotates the nut in the first direction or the second direction by means of the rotation of the spindle so as to move forward or backward a relative position of the piston.
