摘要：A coupling device suitable for connecting an externally splined power take-offstub shaft to a corresponding internally splined yoke with a universal joint. The couplingmechanism includes an automatic release to the locked position and locks axially ontothe shaft by way of locking balls. A collar with flexible tabs is manually rotatable to theunlocked position and is triggered to rotate to the locked position by the locking balls.When the externally splined shaft is inserted into the internally splined yoke, the end ofthe shaft trips the balls causing the flexible tabs in the collar to move radially outward,releasing the collar which rotates to the locked position. The collar rotates camming theballs on a formed metal ring inside the plastic collar to the locked position. Rotation isproduced by a fully enclosed torsional spring connected to the collar and the yoke andprevents over-rotation in either direction. When the coupling device is in the lockedposition the flexible tabs rest in recesses on the sides of the yoke in the relaxed mode.
