GIMBAL JOINT AND METHOD OF ITS MAINTENANCE Russian patent published in 2012 - IPC F16D3/41 F16C11/06 F16D3/28 

FIELD: machine building.

SUBSTANCE: gimbal joint comprises forks, needle bearings 2 and cross 1 with pins and system of lube channels 4, 7 to communicate axial channels in said pins converging at the center of cross 1 with cross orifices receiving grease cup and discharge valve. Cross body channels are divided into two types: channels 7 with grease and channels 4 with filling agent.
