Abstract

The invention relates to an articulation with rotating hydraulic connection, in particular for mobile work machines. In a very compact structure a hollow internal body (4) and an external body (1) are rotatingly coupled, with their respective cylindrical surfaces (3) and (5) placed in contact. The hydraulic rotating connection is realised by means of the coupling between the annular channels (2) envisaged in the external body (1) and the open ends (6) arranged in the hollow internal body (4). A motor (8), solidly mounted to the hollow internal body (4), activates a shaft (9), which is the drive shaft of an epicyclic reduction gear (16), (20), which latter is coaxial and reciprocally connects the hollow internal body (4) with the external body (1). A clutch (10) is interposed to operate between the shaft (9) and the hollow internal body (4). <IMAGE>
