hydraulic system operates between a first and a second marine powertrain

摘要

The present invention relates a hydraulic system (1) arranged between a first marine propulsion device (2, 42) and a second marine propulsion device (3, 43), which are each arranged so that they can rotate about a respective axis (6, 7, 46, 47) at a distance from one another. The system (1) comprises a first hydraulic piston-cylinder device (8, 50) and a second hydraulic piston-cylinder device (13, 55) arranged between said second propulsion device (2, 3, 42, 43) and an element (12, 17, 54, 59) fixed in relation to said axis (6, 7, 46, 47). Connecting the piston-cylinder devices (8, 13, 50, 55) to one another via a first hydraulic circuit (18, 60) and a second hydraulic circuit (19, 61) leads to that rotating of one propulsion device (2, 3, 42, 43) results in rotation of the other propulsion device (2, 3, 42, 43). This affords the function of a tie bar.
