Abstract
A charging mechanism charges a stored-energy spring of a stored-energy spring mechanism. The charging mechanism contains a charging gear coupled to the stored-energy spring, an intermediate shaft coupled to the charging gear, an idler gear driven by a charging motor, a freewheel coupled to the idler gear, and a dog clutch that couples the freewheel to the intermediate shaft to charge the stored-energy spring and uncouples same from the intermediate shaft in the charged state. The dog clutch contains a first clutch block that is non-rotatably coupled to the intermediate shaft, a second clutch block connected to the freewheel, and a synchronizer ring arranged between the clutch blocks and is non-rotatably coupled to the first clutch block. During a rotation relative to the second clutch block, the synchronizer ring couples in a form-fitting manner to the second clutch block in a first direction of rotation about the axis of rotation.
