Abstract

본 발명은 전기로 작동되는 차량 브레이크용 작동기에 관한 것이다. 전기로 작동되는 차량 브레이크에서는 제동에 필요한 힘이 스핀들 구동부에 의해 부가의 변속기단(들) 또는 부가의 부품없이 얻어져야 한다.The present invention relates to an electrically operated actuator for vehicle brakes. In electrically operated vehicle brakes, the force required for braking must be obtained by the spindle drive without additional transmission stage (s) or additional components.

이것은 브레이크 블록이 전기 구동부로서 사용되는 전동기(4)에 의해 브레이크 디스크에 매칭되고, 전동기(4)는 브레이크 블록의 이동방향으로 배치된 스핀들을 통해 브레이크 블록에 작용하는, 축방향으로 이동가능하게 지지된 브레이크 피스톤(32)에 연결되도록 구성되, 브레이크 작동기(2)에서 이루어진다. 여기서, 전동기(4)의 축의 연장부는 스핀들 로드(18)로서 사용된다. 브레이크 피스톤(32)은 비틀림으로부터 보호되고 스핀들너트(20)와 함께 하나의 넌포지티브 유니트를 형성한다.This is because the brake block is matched to the brake disc by the electric motor 4 used as the electric drive part and the electric motor 4 is supported on the brake block via the spindle arranged in the moving direction of the brake block, And is made to be connected to the brake piston (32), and is made in the brake actuator (2). Here, the extension of the shaft of the electric motor 4 is used as the spindle rod 18. The brake piston 32 is protected from twisting and forms one non-positive unit with the spindle nut 20. [

대체 실시예에 따르면, 전동기(4)의 회전자(8)가 스핀들 너트(20)에 비틀림없이 연결된다. 그것의 중공축은 스핀들 로드(18')의 수용을 가중하게 한다. 본 발명은 "브레이크-바이-와이어" 타입의 전기로 작동되는 브레이크에 적용된다.According to an alternative embodiment, the rotor 8 of the electric motor 4 is connected to the spindle nut 20 without twisting. Its hollow axis will increase the acceptance of the spindle rod 18 '. The present invention is applied to electrically operated brakes of the "brake-by-wire" type.
