Abstract

Elektrohydraulischer Aktuator mit einem Elektromotor (1), einem dem Elektromotor (1) wirkungsmäßig nachgeschalteten Rotations-Translationsgetriebe (2), das eine Gewindespindel (13) sowie eine Gewindemutter (14) aufweist, mit mindestens einem ersten Kolben (3a, 3b), der mindestens einen ersten hydraulischen Druckraum (4a, 4b) begrenzt, sowie mindestens einem zweiten Kolben (5a, 5b), der mindestens einen zweiten hydraulischen Druckraum (6a, 6b) begrenzt, wobei die Translationsbewegung des Rotations-Translationsgetriebes (2) auf die Kolben (3a, 3b, 5a, 5b) übertragen wird, wobei der Elektromotor (1) koaxial zur Gewindespindel (13) bzw. der Gewindemutter (14) und radial umgreifend zu den Kolben (3a, 3b, 5a, 5b) angeordnet ist, die um die Gewindespindel (13) gleichförmig verteilt angeordnet sind.
