Abstract

Eine hydrostatische Maschine umfasst eine erste und eine zweite Axialkolbeneinheit (5, 6), die koaxial angeordnet sind und mit einer verstellbaren Steuerscheibe (13, 14) zusammenwirkende Kolben (9) aufweisen. Der ersten Axialkolbeneinheit (5) ist eine erste Steuerscheibe (13) und der zweiten Axialkolbeneinheit (6) eine zweite Steuerscheibe (14) zugeordnet. Die erste und zweite Steuerscheibe (13, 14) sind durch einen Kopplungsmechanismus (17-25; 26-28; 30-33) gemeinsam parallel zueinander verstellbar.
