Positioning and damper device with the use of a shearing force of a cyclic differential compressive stress of a crosslinked thermoplastic

摘要

A positioning device comprises a first (22), a second (24) and a third (28) element. The first element (22) comprises a crosslinked thermoplastics and the second element (24) is not circular and adjacent to a first side of the first element (22) are formed, and for a relative rotation to the first element about an axis. The third element is adjacent to a second side of the first element, formed. The first, second and third element are designed in such a way that a first compressive stress quantity to the first element is induced, whereas no relative rotation between the first and the second element is present, and a second compressive stress quantity to the first element is induced, while a relative rotation between the first element and the second element is present. The second compressive stress quantity is at least three times higher than the first compressive stress quantity.
