Abstract
The invention relates to a swashplate pivot bearing (10) in an adjustment unit of a hydraulic axial piston machine (1) with a timing/tracking mechanism (20) for the cage (14) of a roller bearing arrangement (11). The timing/tracking mechanism (20) is in this case distributed to the two end regions (16, 17, 18) of the roller bearing arrangement (11) in such a way that one part is active only during the pivoting of the swashplate (7) in one direction and the other part is active only during pivoting in the other direction. The timing/tracking mechanism (20) is preferably designed in the manner of a slotted-link control with guide tracks (24, 25, 26) and with a guide element (27, 28).
