Abstract
간접적인 또는 직접적인 고정부를 가지는, 특히 진동 픽업을 위한 압축 부시가 제공되고, 이 간접적인 또는 직접적인 고정부는 중앙 리세스(12)를 통해 상기 압축 부시(2)에서 유도되고 그리고 지지면(3)을 가지는 압축 부시를 진동을 야기하는 부재, 예를 들어 내연 기관에 클램핑한다. 검출 수단(6), 특히 피에조 세라믹 디스크가 방사상 외부에 상기 압축 부시(2)에 동축의 예비 응력 하에 지지된다. 이 스프링을 위한 정지부는, 상기 압축 부시(2)의 (금속성) 재료의 코킹을 통해 만들어질 수 있는 압축 부시(2)의 외측 둘레에서 적어도 2개의 융기부(20), 바람직하게는 5개의 융기부로 이루어진다.
Description
