Abstract

An apparatus for wear compensation for an actuator comprises: a linear actuator (110) for performing a linear actuation during normal operation; a preloading element (120) for providing a preloading force; and a coupling element (130) with a variable length (L) for coupling the linear actuator (110) with the preloading element (120) such that the linear actuation of the linear actuator (110) exerts a linear force on the preloading element (120). The coupling element (130) comprises a first chamber (134a), a second chamber (134b), and at least one passage (139) connecting the first chamber (134a) with second chamber (134b). The first chamber (134a) and the second chamber (134b) each comprises a variable volume to enable a change of the length (L), wherein the first chamber (134a) and/or the second chamber (134b) are filled with a shear-thickening fluid .
