Abstract

특히 진동 픽업을 위한 압축 부시가 제공되고, 이것은 중앙리세스(12)를 통해 간접적인 또는 직접적인 고정부로 진동을 야기하는 부재, 예를 들어 내연 기관에 클램프될 수 있다. 검출 수단(6)이 외부에 상기 압축 부시(2)에 제공된 예비 응력 하에 설치되고, 이 경우 상기 예비 응력을 형성하는 스프링(8)을 위한 정지부가 존재한다. 이 정지부는 고정된 장소에서 클램핑가능한 고정부재(20;21;23)로 이루어지고, 이것은 상기 에워싸는 부재들(4, 5, 7)과 스프링(8)과 함께 상기 검출 수단(6)을 결합하여 외부에서 이 압축 부시(2)에 설치될 수 있고 이것을 동축 방향으로 클램핑할 수 있다. 이 고정 부재는 고정 디스크(20), 스냅링(21) 또는 수축가능한 링(23)이 될 수 있다.In particular, a compression bushing for the oscillating pick-up is provided, which can be clamped to a member, e.g. an internal combustion engine, which causes oscillation to an indirect or direct fixation via the central recess 12. A detecting means 6 is provided externally under the pre-stress provided on the compression bush 2, in which case there is a stop for the spring 8 which forms the pre-stress. This stop consists of a clamping member (20; 21; 23) which can be clamped in a fixed location, which combines the detection means (6) together with the surrounding members (4, 5, It can be installed externally on the compression bush 2 and clamped in the coaxial direction. The fixing member may be a fixed disk 20, a snap ring 21, or a shrinkable ring 23.
