Abstract:
1. A swashplate-type pivot bearing, comprising: a housing section; a swashplate section; rolling bodies, with the swashplate section being pivotably mounted in the housing section by the rolling bodies, with the rolling bodies being arranged in at least one rolling body row in at least one of a full-roller configuration and a cage-free configuration, the at least one rolling body row having a first end and a second end opposite the first end; and a first follow-up device arranged at the first end of the at least one rolling body row and a second follow-up device arranged at the second end of the at least one rolling body row, each of the first and second follow-up devices being movable relative to each of the swashplate section and the housing section during a pivoting movement of the swashplate-type pivot bearing, wherein the first follow-up device is controlled by a slotted guide of the first follow-up device, the second follow-up device is controlled by a slotted guide of the second follow-up device, each of the first and second follow-up devices is configured as an end stop for the rolling bodies, the first follow-up device is moved by the slotted guide of the first follow-up device concomitantly with the rolling bodies during the pivoting movement of the swashplate-type pivot bearing, the second follow-up device is moved by the slotted guide of the second follow-up device concomitantly with the rolling bodies during the pivoting movement of the swashplate-type pivot bearing, wherein each slotted guide has a first guide slot, which is fixedly connected with the housing section, and a second guide slot, which is fixedly connected with the swashplate section, the first follow-up device has a first bolt that engages into the first guide slot and the second guide slot of the slotted guide of the first follow-up device, the second follow-up device has a second bolt that engages into the first guide slot and the second guide slot of the slotted guide of the second follow-up device, wherein the first guide slots are inserted on or in a raceway of the housing section, with a longitudinal extent of each of the first guide slots being inclined with respect to a longitudinal extent of the raceway of the housing section by a first acute angle, wherein the second guide slots are formed on or in a raceway of the swashplate section, with a longitudinal extent of each of the second guide slots being inclined with respect to a longitudinal extent of the raceway of the swashplate section by a second acute angle, the first acute angle and the second acute angle differing in magnitude from one another.
