A brake actuator of the present invention is disclosed. According to one aspect of the present invention, a brake actuator may be provided which presses a piston toward a brake pad or releases the pressing, and is controlled by an electrical signal, the brake actuator comprising: a power generation unit for generating power by an electrical signal; a spindle member rotating by receiving the power from the power generation unit, and having a first screw part formed on the outer peripheral surface thereof; and a nut member for pressing a piston or releasing the pressing, and having a second screw part, engaging with the first screw part, formed on the inner peripheral surface thereof, wherein, for the first screw part, a pitch size between neighboring screw threads changes along the rotating direction according to a predetermined cycle.

    L'invention concerne un actionneur de frein. Selon un aspect de la présente invention, un actionneur de frein peut être fourni, qui presse un piston vers un patin de frein ou libère le pressage, et est commandé par un signal électrique, l'actionneur de frein comprenant : une unité de génération d'énergie pour générer de l'énergie par un signal électrique ; un élément broche tournant par réception de l'énergie provenant de l'unité de génération d'énergie et ayant une première partie vis formée sur sa surface périphérique externe ; et un élément écrou pour presser un piston ou libérer le pressage et ayant une seconde partie vis, venant en prise avec la première partie vis, formée sur sa surface périphérique interne, pour la première partie vis, une taille de pas entre des filetages de vis voisins changeant le long de la direction de rotation selon un cycle prédéterminé.

    본 발명의 브레이크 액츄에이터가 개시된다. 본 발명의 일 측면에 따르면, 피스톤을 브레이크 패드 측으로 가압 또는 가압해제하며, 전기적 신호에 의해 제어되는 브레이크 액츄에이터에 있어서, 전기적 신호에 의해 동력을 발생시키는 동력발생부; 동력발생부에서 동력을 전달받아 회전하고, 외주면에 제1 나사부가 형성되는 스핀들부재; 피스톤을 가압 또는 가압 해제하고, 내주면에 제1 나사부와 치합하는 제2 나사부가 형성되는 너트부재;를 포함하고, 제1 나사부는 이웃한 나사산 사이의 피치의 크기가 회전 방향을 따라서 일정한 주기로 변화하는 브레이크 액츄에이터가 제공될 수 있다.
