Abstract
A torque fuse device having a bi-directional release mechanism that releases the torque carrying capability of the shafts upon torque overload is provided. The torque fuse device includes a sleeve, a hub positioned within the sleeve, and a hydraulic torque coupler. The sleeve and the hub are adapted to be coupled with two axially aligned shafts. The hub includes a feedback ring having at least one tooth formed therein. The hydraulic torque coupler includes a piston, a cylinder and a collet. The piston is positioned between the collet and the feedback ring and slides along an inclined surface of collet. One ore more fuse pins are selectively positioned between the tooth, the piston and the cylinder to frictionally engage the sleeve to the hub. Upon a torque overload condition, the pins release from the teeth thereby releasing the torque carrying capability of the shafts.
