Abstract
A swashplate type hydraulic axial piston machine whose swashplate is arranged on a rocker mounted to pivot in a segmental rolling contact bearing has a tracking device for the cage of the pivot bearing which comprises a rod-like guide element which is connected to said rocker in a first bearing in the rocker so that it can pivot parallel to the pivot plane (SE), is connected to said cage in a second bearing so that it can pivot parallel to the pivot plane (SE) and so that it can be displaced longitudinally, and is mounted to pivot parallel to the pivot plane (SE) in a third bearing. To make tracking by the cage possible without mounting the guide element on the housing, a rocker adjustment member is provided mounted so that it can be displaced transverse to the middle axis of the axial piston machine, and the third bearing is arranged on a guide member movably connected to the adjustment member and the rocker.
