Abstract
Torque tools of the present invention include: a hydraulic cylinder assembly (); a drive assembly (); a flexible linkage connection, or force transfer, assembly formed between the hydraulic cylinder assembly () and the drive assembly (); all of which is formed within or adjacent to a housing assembly (). They provide large, accurate torque for limited clearance applications. The flexible linkage connection assembly () includes a rocker arm assembly () and a chain link-pin assembly. The flexible linkage connection assembly () maintains the relationship between the line of action of the linear force generated on the rocker arm assembly () by the hydraulic piston assembly ()(ies) and rotary force generated on the ratchet drive socket () by the rocker arm assembly () via the chain link-pin assembly at close to the optimized position throughout the entire travel of a drive plate assembly () of the drive assembly (). The resulting efficiency increase of converting linear force and displacement into rotary torque and angular displacement allows for generation of large and accurate torque in minimal cross-sections necessary to access hidden, limited clearance and/or inaccessible threaded fasteners.
