Abstract
A trunnion cross for connecting two yokes. The trunnion cross includes two pairs of trunnions, wherein each pair is located diametrically opposite each other and extends along an axis, wherein the two axes of the trunnion pairs extend perpendicularly to each other. Each trunnion is received in a roller bearing mounted in an eye of the yoke. The trunnion cross defines two throughbores extending perpendicularly to each other. Cylindrical throttle inserts are inserted in the throughbores for pressure redcution. A thread is formed on the outer circumference of each throttle insert defining a throttle passage. The throttle inserts ensure a uniform reduction of the lubricant pressure within the trunnion cross toward all four trunnion bearing. The danger of a clogging of a lubricant duct by dirt particles is reduced. Any plugs formed by hardening lubricant which cause clogging of a lubricant duct can be ejected.
