Abstract:
1. A decoupling sleeve, comprising: a coaxial driven shaft assembly, including: a coaxial driving shaft; a set of dog clutch jaws, the dog clutch jaws configured to connect the driving shaft to the driven shaft, and to allow the driving shaft to transmit engine torque to the driven shaft in a forward direction of rotation; and a connecting member having a connecting member thread, the connecting member configured to be connected to the driving shaft, said connecting member adapted to be connected to the driven shaft via a threaded interface to the nut, the threaded interface configured to allow the connecting member to detach from the nut after an event of reverse torque beyond a threshold so that the driven and driving shafts become free in rotation relative to one another, the threaded interface including the nut thread and the connecting member thread, wherein the return spring is configured to exert an axial force on the threaded nut and the driven shaft, and the spring is configured to increase a distance between the nut thread and the connecting member thread when the nut and the connecting member detach after the reverse torque beyond the threshold.
