Abstract

An apparatus is disclosed for producing a frictional and/or form-fitting connection between first and second components which are linearly or rotationally movable relative to one another for transmitting forces and/or force moments that act between the first and second components in a linear and/or rotational manner. The first component surrounds the second component, at least sectionally, with at least one inner wall that faces the second component. The second component features at least one active-face element that can be transferred in a force-loaded manner from a first position, in which the active-face element is spaced apart from the inner wall, into a second position, in which the active-face element produces the frictional and/or form-fitting connection with the inner wall. The invention includes at least one mechanical stressing element for exerting a restoring force upon the active-face element which holds the active-face element in a first position, and a kinematic system acts upon the active-face element opposite to the restoring force and is driven exclusively by a converter material, with the kinematic system transferring the active-face element into the second positi…
