ABSTRACT:
The invention relates to a swash plate swivel bearing for a hydraulic axial piston machine, in which roller-bearing segments are arranged between the hollow cylindrical bearing surface for the swash plate in the housing and the cylindrical bearing surface on the swash plate, which segments are held in curved cages with each of which is associated a tracker having a tracking mechanism guided by a guide member in a first guide, which mechanism is in drive connection with a carrier of the cage. It is the object of the invention to design a swash plate swivel bearing of the construction indicated above so that the guide member can cooperate directly with the carrier of the cage. This is achieved by forming the first guide (23) by two guides grooves (24, 25) that are opposed and, in particular, symmetrically inclined towards the direction of movement (29), the guide grooves crossing one another and being arranged on opposed and substantially parallel surfaces (26,27) on the housing side and on the swash plate side, the guide member (21) being guided in the guide grooves (24,25) always at their point of intersection (31).
